The development of sustainable fiber-reinforced polymers (FRP) to substitute non-renewable plastics from fossil fuels with more abundant biomass-based materials remains a big challenge. Bioresource-based FRP composites produced using 2,5-Furandicarboxylic acid (FDCA) as a green platform chemical and natural fibers as reinforcement are of growing interest in solving the issues of global sustainability. This paper aims at the development of natural fiber reinforced FDCA-derived poly(ester-urethane–acrylate) (PEUA) oligomer as a matrix resin for composite fabrication using flax, jute, ramie, and cotton reinforcements. Water uptake, mechanical and thermal properties of the obtained composites have been investigated. The cotton reinforced PEUA displayed higher tensile (61.6 MPa) and flexural (75.2 MPa) strengths and smaller moisture diffusion coefficient when compared to the other composites. The mechanical properties of the untreated FRP composites were not significantly improved after the permanganate and alkaline chemical treatments due to their higher fiber-matrix interaction as compared with modified ones. The overall results confirmed the suitability of the natural fiber-reinforced FDCA-derived PEUA composites to be employed as lightweight materials for different applications including the automotive engineering.

Green architecture, engineering, and construction (AEC) projects are deemed more complicated compared with their traditional counterparts. They have been reported to have relatively more frequent delays and higher cost growth. The AEC literature has repeatedly highlighted the importance of leadership for sustainable design and construction and the need for team integration for optimal outcomes. However, studies exploring leadership in the context of green AEC projects are limited. Transformational leadership is a highly regarded theory that is known for its potential to effectively facilitate team integration. This empirical study tests the role of shared transformational leadership received by team members in improving team performance through team integration for green AEC project teams. We collected data from 103 individuals working in nine Leadership in Energy and Environmental Design (LEED) projects in the US. We analyzed the data using structural equation modeling (SEM). Our findings suggest that transformational leadership received by team members is positively related with perceived team performance, and this relationship is mediated through perceived team integration. The study is a pioneer in examining leadership for sustainability and mediation effects of team integration in the AEC literature. The outcomes urge for a change in green AEC project teams to think beyond project delivery systems and practices and incorporate transformational leadership across organizational and communicational tiers of project teams through team procurement, project management, and skill development and training.

The past two decades have witnessed rapid advances in engineering individual microbial strains to produce biochemicals and biomaterials. However, engineering microbial consortia has been relatively slow. Using systems and synthetic biology approaches, researchers have been developing tools for engineering complex microbiota. In this opinion article, I discuss future directions and visions regarding developing microbiota as a biomanufacturing host. Specifically, I propose that we can develop the soil microbial community itself as a huge bioreactor. Ultimately, researchers will provide a generalizable system that enables us to understand a microbial consortium's interaction and metabolism on diverse temporal and spatial scales to address global problems, including the climate crisis, food inequality, the issue of waste, and sustainable bioproduction. Recent technological advances enable microbiota engineering for sustainable biomanufacturing. Soil can be viewed as a huge bioreactor to capture carbon dioxide and provide nutrients (e.g., fixed nitrogen) and high-value chemicals and materials. Soil communities are complex, making them a challenge to understand and engineer. This opinion article provides a generalized approach to understanding and engineering the interactions and metabolism in microbial consortia on diverse temporal and spatial scales to address global problems, including the climate crisis, food inequality, waste issues, and sustainable bioproduction.

Chemical engineers play an important and irreplaceable role in addressing all, if not most, of the grand challenges mankind faces. Chemical engineering knowledge has been crucial in advancing the current industrial sectors. This perspective paper attempts to outline the contributions of chemical engineering knowledge to the oil palm biomass industry, a green industry that converts waste into value-added products (e.g. energy, fuel, and chemicals). Several examples are presented to show how the three core chemical engineering knowledge subjects (i.e. (i) reaction engineering, (ii) multi-component/multi-phase separation, and (iii) process systems engineering (PSE)) have been applied in the industry. Apart from that, specific perspectives on the industry's future outlook are also given in this work. Generally, the illustrated potential areas in all three aspects (i.e. micro-scale, meso-scale, and macro-scale) have been discussed with several illustrative examples. This perspective paper aims to capture the state-of-the-art applications of chemical engineering knowledge in the oil palm biomass industry. It serves as a short note to recognise the importance of the chemical engineering domain and offer insights for future and current chemical engineers in advancing the oil palm biomass industry. [Display omitted] • Significant contributions of chemical engineering to the oil palm biomass industry. • State-of-the-art applications of core chemical engineering knowledge. • Perspective on future industrial advancement from micro, meso and macro scale.

Distillation has held a very strong position in the chemical process industries for well over a century, and has, as a separation method, been around for millennia. The process can be designed directly without the need for experimentation unlike other novel separation processes, and distillation is a standard part of any undergraduate curriculum. So why the ongoing interest in this separation dinosaur? Due to distillation's significant importance in industry, and its associated high energy requirements and thereby contribution to global warming, considerable effort is still needed to make the process more energy efficient, as well as to consider other heating sources beyond traditional fossil fuels. In this work, we will outline the most significant methods currently considered for energy efficiency of distillation, and provide an overview of where we may be heading as a discipline in our quest for a more sustainable chemical engineering future. We will argue that significant improvements have already been made, but more is still required by both industry and legislators. We need to consider a future without the use of fossil fuel-based feedstock or energy sources and switch towards renewable sources, and our future graduates need to be adequately prepared for such a future. • Distillation remains the most important separation method in the chemical industries. • Distillation is energy intensive and there is a need for better energy efficiency. • Intensified processes incl. reactive, hybrid or dividing wall columns, are needed. • Electrification can, with incentives, be an alternative energy source to fossil fuel. • Advanced distillation methods must be part of undergraduate degree programmes.

In this study, a microstrip patch antenna design with a U-shaped patch and a paper-based substrate is presented. Metallic parts such as the patch, ground plane and microstrip line feed are designed in aluminum. Utilization of recyclable paper and aluminum yields a sustainable and environmentally friendly design. The dual-band antenna operates between 1.950-2.125 GHz and 2.650-2.825 GHz with a bandwidth of 0.175 GHz for both frequency ranges. It is suitable for multipoint distribution systems (2.076-2.111 GHz) and WiMAX application (2.700--2.800 GHz). Monopolar radiation patterns are obtained for the operation frequencies of both frequency ranges. Maximum gain values are 5.009 dBi and 5.413 dBi for the operation frequencies of multipoint distribution systems and WiMAX application, respectively. While the antenna can be used indoors and outdoors, radome design is not considered in the structure. No parasitic elements or slots are included in the antenna. All simulations are carried out by using ANSYS HFSS software package. [ABSTRACT FROM AUTHOR]

Seasonal or degradational thaw subsidence of permafrost terrain affects the landscape, hydrology, and sustainability of permafrost as an engineering substrate. We perform permafrost thaw sensitivity prediction via supervised classification of a feature set consisting of geological, topographic, and multispectral variables over continuous permafrost near Rankin Inlet, Nunavut, Canada. We build a reference classification of thaw sensitivity using process-based categorization of seasonal subsidence as measured from differential interferometric synthetic aperture radar whereby categories of thaw sensitivity are reflective of ground ice conditions. Classification is performed using a neural network trained on both dispersed and parcel-based reference data. For Low, Medium, High, and Very High thaw sensitivity categories, generalized classification accuracy is 70.8% for 20.6 km2 of dispersed training data. In all cases, the majority classes of Low and Medium thaw sensitivity are predicted with higher accuracy and more certainty, while the minority classes of High and Very High thaw sensitivity are underpredicted. Minority classes can be combined to improve accuracy at the expense of a reduced level of discrimination. The two-class problem can be classified with an accuracy of 81.8%, thereby effectively distinguishing between stable and unstable ground. The method is applicable to similar Low-Arctic permafrost terrain with geological and topographical controls on thaw sensitivity. However, generalized accuracy is reduced for parcel-based training, indicating that reference samples are not totally representative for inference beyond the parcel, and any deployment of the network to other geographical regions would benefit from full or partial retraining with local data.

Purpose: This paper aims to analyze how a tangram activity improved students' abilities to explain sustainability, articulate a positive perception of sustainable design and relate sustainability with innovation in engineering design. Design/methodology/approach: The concept of paradigm shift was introduced in the classroom by using a tangram activity to help students understand that sustainable design requires out-of-the-box thinking. Instructors from three institutions teaching various levels of sustainability courses to engineering majors used the activity to introduce sustainable design, then measured the understanding and appreciation of the concepts introduced through the tangram activity with pre- and post-activity surveys. Findings: Findings from the study indicate that students' perceptions of sustainability significantly improved due to the activity, without regard to the institution. The activity also significantly improved students understanding of the connection between sustainability and innovation, across all three institutions, across all majors and across all years of study except second-year students. Improving engineering students' views on sustainability may lead, over time, to changes in the industry, in which environmental performance is incorporated into the engineering design process. Originality/value: Active learning approaches are needed for affective-domain learning objectives in the sustainability field for students to learn the necessary attitudes, values and motivations to implement sustainability in engineering design. Simple, easily implemented active learning techniques, such as the tangram activity presented here, can be implemented across the curriculum or to the public to introduce the paradigm shift necessary with sustainable design.

Purpose: This paper aims to explore the differences in first-year and senior engineering students' engineering agency beliefs and career goals related to sustainable development. The authors also sought to understand how topics related to sustainable development in engineering courses affect senior engineering students' goals to address these issues in their careers. This work provides evidence of how students' agency beliefs may be shaped by higher education, which is essential to workforce development. Design/methodology/approach: Findings stem from two national surveys of engineering first-year (Sustainability and Gender in Engineering, n = 7,709) and senior students (Student Survey about Career Goals, College Experiences, n = 4,605). The authors compared both groups using pairwise testing by class standing. Findings: The results indicate that undergraduate studies tend to reinforce students' engineering agency beliefs to improve their quality of life and preserve the environment. Significantly more senior students selected career goals to address environmental issues compared to first-year students. In general, students undervalue their roles as engineers in addressing issues related to social inequities. Those topics are rarely addressed in engineering courses. Findings from this work suggest discussing sustainability in courses positively impact setting career goals to address such challenges. Research limitations/implications: The study compares results from two distinct surveys, conveyed at different periods. Nonetheless, the sample size and national spread of respondents across US colleges and universities are robust to offer relevant insights on sustainable development in engineering education. Practical implications: Adapting engineering curriculum by ensuring that engineering students are prepared to confront global problems related to sustainable development in their careers will have a positive societal impact. Social implications: This study highlights shortcomings of engineering education in promoting social and economic sustainability as related to the engineering field. Educational programs would benefit from emphasizing the interconnectedness of environmental, social and economic dimensions of sustainable development. This approach could increase diversity in engineering education and the industry, and by ripple effect, benefit the communities and local governance. Originality/value: This work is a first step toward understanding how undergraduate experiences impact students' engineering agency beliefs and career goals related to sustainability. It explores potential factors that could increase students' engineering agency and goals to make a change through engineering. [ABSTRACT FROM AUTHOR]

Insulating polymeric foams have an important role to play in increasing energy efficiency and therefore contributing to combating climate change. Their development in recent years has been driven towards the reduction of thermal conductivity and achievement of the required mechanical properties as main targets towards sustainability. This perception of sustainability has overseen the choice of raw materials, which are often toxic, or has placed research efforts on optimizing one constituent while the other necessary reactants remain hazardous. The transition to the circular economy requires a holistic understanding of sustainability and a shift in design methodology and the resulting research focus. This paper identifies research needs and possible strategies for polymeric foam development compatible with Circular Product Design and Green Engineering, based on an extensive literature review. Identified research needs include material characterization of a broader spectrum of polymer melt–gas solutions, ageing behavior, tailoring of the polymer chains, detailed understanding and modeling of the effects of shear on cell nucleation, and the upscaling of processing tools allowing for high and defined pressure drop rates.

Single-use, disposable, point-of-care diagnostic devices carry great promise for global health, including meeting urgent needs for testing and diagnosis in places with limited laboratory facilities. Unfortunately, the production and disposal of single-use devices, whether in lateral flow assay, cartridges, cassettes, or lab-on-chip microfluidic format, also poses significant challenges for environmental and human health. Point-of-care devices are commonly manufactured from unsustainable polymeric materials derived from fossil sources. Their disposal often necessitates incineration to reduce infection risk, thereby creating additional release of CO2. Many devices also contain toxic chemicals, such as cyanide derivatives, that are damaging to environmental and human health if not disposed of safely. Yet, in the absence of government regulatory frameworks, safe and sustainable waste management for these novel medical devices is often left unaddressed. There is an urgent need to find novel solutions to avert environmental and human harm from these devices, especially in low- and middle-income countries where waste management infrastructure is often weak and where the use of point-of-care tests is projected to rise in coming years. We review here common materials used in the manufacture of single-use point-of-care diagnostic tests, examine the risks they pose to environmental and human health, and investigate replacement materials that can potentially reduce the impact of microfluidic devices on the production of harmful waste. We propose solutions available to point-of-care test developers to start embedding sustainability at an early stage in their design, and to reduce their non-renewable plastic consumption in research and product development.

Diterpenoids display a large and structurally diverse class of natural compounds mainly found as specialized plant metabolites. Due to their diverse biological functions they represent an essential source for various industrially relevant applications as biopharmaceuticals, nutraceuticals, and fragrances. However, commercial production utilizing their native hosts is inhibited by low abundances, limited cultivability, and challenging extraction, while the precise stereochemistry displays a particular challenge for chemical synthesis. Due to a high carbon flux through their native 2-C-methyl-D-erythritol 4-phosphate (MEP) pathway towards photosynthetically active pigments, green microalgae hold great potential as efficient and sustainable heterologous chassis for sustainable biosynthesis of plant-derived diterpenoids. In this study, innovative synthetic biology and efficient metabolic engineering strategies were systematically combined to re-direct the metabolic flux through the MEP pathway for efficient heterologous diterpenoid synthesis in C. reinhardtii. Engineering of the 1-Deoxy-D-xylulose 5-phosphate synthase (DXS) as the main rate-limiting enzyme of the MEP pathway and overexpression of diterpene synthase fusion proteins increased the production of high-value diterpenoids. Applying fully photoautotrophic high cell density cultivations demonstrate potent and sustainable production of the high-value diterpenoid sclareol up to 656 mg L−1 with a maximal productivity of 78 mg L−1 day−1 in a 2.5 L scale photobioreactor, which is comparable to sclareol titers reached by highly engineered yeast. Consequently, this work represents a breakthrough in establishing a powerful phototrophic green cell factory for the competetive use in industrial biotechnology. • Systematic identification of bottlenecks from the MEP pathway in C. reinhardtii. • Enzymatic fusion channels improved flux through MEP pathway towards diterpenoids. • Potent toolkit for diterpenoid production in microalgae established. • Photoautotrophic high cell density cultivation improves diterpenoid production. • Combined engineering strategies enable sclareol production up to 656 mg L−1.

Summary: Kesterite Cu2ZnSnS4(CZTS) thin‐film technology has been comprehensively investigated over the last decade as a promising candidate in the field of photovoltaic technologies. However, despite numerous strategies to improve the performance, the efficiencies remain stagnant at around 11%. Poorly optimized absorber/buffer interface, non‐absorption of higher wavelength photons, and non‐ohmic back contact are the primary reasons for the poor performance of the CZTS solar cell. The authors of this paper propose a cadmium‐free buffer layer, multiple quantum wells (MQWs) structure, and a back surface field (BSF) layer to overcome these issues, respectively. In this study, the buffer layer, zinc oxysulfide (Zn[O1−xSx]) is considered as an alternative to toxic Cadmium Sulfide (CdS) for better band alignment with the CZTS absorber layer. Cu2ZnSn(SxSe1−x)4 (CZTSSe) is used as a quantum well material in MQWs to increase photon absorption in CZTS solar cells. Tin selenide (SnSe) is used as the BSF layer to reduce the effect of non‐ohmic back contact and to improve the open‐circuit voltage (Voc) of MQW incorporated CZTS solar cells. Detailed analysis and optimization of the modified structure with higher performance are presented. The simulation results obtained provide imperative guidelines for the fabrication of high‐efficiency CZTS solar cells using non‐toxic and earth‐abundant materials. [ABSTRACT FROM AUTHOR]

Applications of ultra-low-pressure filtration systems are increasing as they offer enhanced sustainability due to lower energy input, almost no use of chemicals, and minimum operational expenditure. In many cases, they operate as a decentralized system using a gravity-driven membrane (GDM) filtration process. These applications are relatively new; hence, the fundamental knowledge of the process is still limited. In this study, we investigated the phenomenon of polymeric membrane compaction under an ultra-low-pressure system. The compaction phenomenon is well-recognized in the traditional pressure-driven system operating at high transmembrane pressures (ΔPs > 200 kPa), but it is less documented in ultra-low-pressure systems (ΔP < 10 kPa). A simple GDM filtration setup operated under a constant-pressure system was employed to investigate the compaction phenomena in a polymeric hollow fiber membrane for clean water filtration. Firstly, a short-term pressure stepping test was performed to investigate the occurrence of instantaneous compaction in the ΔP range of 1–10 kPa. The slow compaction was later investigated. Finally, the compaction dynamic was assessed under alternating high and low ΔP and relaxation in between the filtrations. The findings demonstrated the prominence of membrane compaction, as shown by the decreasing trend in clean water permeability at higher ΔPs (i.e., 3240 and 2401 L m−2 h−1 bar−1 at ΔPs of 1 and 10 kPa, respectively). We also found that the intrinsic permeability of the applied polymeric membrane was significantly higher than the apparent one (4351 vs. 2401 L m−2 h−1 bar−1), demonstrating >50% loss due to compaction. The compaction was mainly instantaneous, which occurred when the ΔP was changed, whereas only minor changes in permeability occurred over time when operating at a constant ΔP. The compaction was highly reversible and could be restored (i.e., decompaction) through relaxation by temporarily stopping the filtration. A small fraction of irreversible compaction could be detected by operating alternating filtrations under ΔPs of 1 and 10 kPa. The overall findings are essential to support emerging GDM filtration applications, in which membrane compaction has been ignored and confounded with membrane fouling. The role of compaction is more prominent for high-flux GDM filtration systems treating less-fouling-prone feed (i.e., rainwater, river water) and involving membrane cleaning (i.e., relaxation) in which both reversible and irreversible compaction occurred simultaneously.

Photothermal therapy (PTT) has brought hope for cancer treatments, with hyperthermiainduced immunogenic cell death (ICD), which is a critical part of therapeutically induced antitumor immune responses. Limited immune stimulation response in PTT is the primary reason for incomplete tumor ablation, therefore demonstrating urgent requirements for ICD amplifier. Herein, a sub-10 nm supramolecular nanoassembly was formed by coassembly of clinically approved aluminum adjuvant and commonly used indocyanine green (ICG) under the assistance of lignosulfonate (LS, a green and sustainable multifunctional lignin derivative) for localized photothermal-immunotherapy of breast cancer. The overall results revealed that LS-Al-ICG is capable of inducing amplified ICD, efficiently eliciting solid immune responses through dendritic cells (DCs) activation and cytotoxic T-cell responses initiation for tumor killing. Moreover, anti-PD-1 therapy blocked the PD-1 pathway and led to remarkable anti-tumor efficacy against laser-irradiated primary tumors and distant tumors by potentiating systemic tumor specific T cell immunity. The results of this study demonstrate a handy and extensible approach for engineering green natural lignin nanoparticles for cancer immunotherapy, which shows promise for delivering other therapeutics in biomedical applications.

This work demonstrates how to apply the Theory of Inventive Problem Solving (Russian acronym TRIZ) on two industrial‐scale case studies. The first case study addresses processing of mineral metal carbonates, which is characterized by high CO2 emissions and high energy demand. As solver strategy a novel reductive pathway is suggested. The second case study refers to biobased industrial processes, which discharge aqueous effluents with unexploited carboxylic acid loads. Reactive separations are proposed to isolate the carboxylic acids. In both solver strategies, chemical reactions adopt a central role. [ABSTRACT FROM AUTHOR]

Industrial production, military applications, and environmental monitoring all require corresponding positioning functions as science and technology advance. The location information service has gradually grown in popularity. However, large-scale applications will consume a lot of energy and cause environmental issues.

The improvement of triangular location algorithm is used in this paper to realize the research of low-power Bluetooth indoor location using the intelligent control project of green low-carbon buildings as the research object. The results show that the improved algorithm significantly improves the accuracy. The daily monitoring of the elderly and the alarm processing in an emergency are experimentally practiced and analyzed through the research of low-power Bluetooth indoor location algorithm.

More specifically, the findings presented consolidated information that professors and coordinators can use to align materials selection courses with the SDGs better. [ABSTRACT FROM AUTHOR]

Bamboo, as a renewable bioresource, exhibits advantages of fast growth cycle and high strength. Bamboo-based composite materials are a promising alternative to load-bearing structural materials. It is urgent to develop high-performance glued-bamboo composite materials. This study focused on the chemical bonding interface to achieve high bonding strength and water resistance between bamboo and dialdehyde cellulose–polyamine (DAC-PA 4N) adhesive by activating the bamboo surface. The bamboo surface was initially modified in a directional manner to create an epoxy-bamboo interface using GPTES. The epoxy groups on the interface were then chemically crosslinked with the amino groups of the DAC-PA 4N adhesive, forming covalent bonds within the adhesive layer. The results demonstrated that the hot water strength of the modified bamboo was improved by 75.8 % (from 5.17 to 9.09 MPa), and the boiling water strength was enhanced by 232 % (from 2.10 to 6.99 MPa). The bonding and flexural properties of this work are comparable to those of commercial phenolic resin. The activation modification of the bamboo surface offers a novel approach to the development of low-carbon, environmentally friendly, and sustainable bamboo engineering composites.

Natural hazards foster the need for resilience in the built environment, but resilient structures must not interfere with sustainability. The potential trade-offs are increasingly being investigated using performance-based assessments combined with life cycle assessments (LCA) to translate probable building or bridge damage into environmental losses. Leveraging 102 publications intersecting sustainability and resilience in the built environment, this review sheds light on the current methodological challenges and opportunities for integrating natural hazard-induced damage with environmental losses in the built environment. The reviewed literature primarily focused on buildings exposed to seismic hazards, deriving their losses using the best-known LCA mode, attributional LCA. Building and bridge frameworks showed notable methodological distinctions, along with a near absence of consideration of the interactions between climate change and natural hazards or structural vulnerabilities. Based on the findings, 22 opportunities for future research were synthesized. Future research should seek to better assess the total life cycle sustainability of resilient structures by exploring advanced modes of LCA, widening the scope of their assessments, and better integrating uncertainty and sensitivity. Achieving a more sustainable and resilient built environment also requires upcoming research to investigate the practicalities of aligning modeling frameworks, tools, data, and case studies. Addressing these research gaps will assist in anticipating how the built environment can be adapted and shaped to positively contribute to a resilient and sustainable future.

[Display omitted] • Carrier-free delivery systems of pyrimethanil (PYR) were constructed through supramolecular self-assembly. • PYR nano cocrystal suspensions (NCSs) exhibited excellent photostability, thermal stability, and volatile stability. • PYR NCS demonstrated sustained-release properties and exhibited excellent long-term antifungal activity against Botrytis cinerea. The adverse effects resulting from off-target pesticide application pose significant risks to both ecosystems and public health. Therefore, developing a pesticide delivery system that is straightforward, effective, and devoid of secondary pollution is crucial for environmental safety. Herein, self-assembled crystalline materials involved pyrimethanil (PYR) and organic acids were constructed by crystal engineering. These materials allowed for direct manipulation of the physicochemical properties and environmental fate of PYR by the building modules. The melting point of PYR was increased from 96.19 °C to 206.69 °C. The photostability and volatile stability were improved by 3.85-fold and 297-fold, respectively. Afterwards, these crystalline materials were prepared as nano cocrystal suspensions (NCSs) in water by the one-pot method. The PYR NCSs exhibited potent bioactivity against Botrytis cinerea and demonstrated slow-release behavior. Upon foliar spraying, the PYR NCSs exhibited desirable foliar wettability with a contact angle lower than 36°. By limiting leaching into the soil and reducing environmental pesticide exposure, PYR NCS ensured the safety of both earthworms and plants. The structure–property relationships of PYR NCSs were elucidated through intermolecular interaction analysis and theoretical calculations. Overall, the NCSs constructed by the supramolecular chemistry strategy are characterized by the simple preparation, high bioactivity, stability, no carrier, slow-release, and minimal environmental risk, which offers insight for improving the utilization and sustainable management of pesticides.

The efficiency of the perovskite layer generally determines the performance of perovskite solar cells (PSCs). Perovskite solar cells (PSCs) depend highly on the layer's morphology, crystalline structure, and surface defect of their power conversion efficiency (PCE), and long-term stability. Introducing appropriate solvent additives to the perovskite precursor solution effectively controls the film structure, defect passivation, and grain boundaries. In this work, alcohols such as isopropyl alcohol (IPA), ethanol, and methanol (a nontoxic, sustainable, and low-cost alcohol) are used as green solvent additives to enhance the quality and morphology of perovskite films and to control nonradiative recombination in the PSCs. The alcohol adducts containing OH groups have interacted with organic cations and Pb ions to produce PbO, which reduces the concentration of halide vacancies, enhances charge transfer, and decreases nonradiative recombination. Alcohol additives can produce homogeneous, highly crystalline perovskite films with improved charge transfer and reduced recombination. Using the best alcohol additive, IPA, provides power conversion efficiency (PCE) of 20.41% and greater ambient air stability, as it keeps more than 82% of its original PCE after 1000 h. Furthermore, IPA additive-based PSCs retain 81% and 80% of their original efficiencies after 500 and 350 h of continuous light irradiation and heating at 85 °C. [Display omitted] • Alcoholic is introduced as a functional green organic additive for perovskites. • Alcohol additives with OH groups interacted with organic cations and the Pb ion to form PbO. • Additives improve the perovskite film structure, defect passivation, and grain boundaries. • Additives promote charge transportation/extraction capabilities and reduce nonradioactive recombination. • IPA additive-based PSCs show a higher cell-efficiency and better stability.

Nanostructured materials are fascinating since they are promising for intensely enhancing materials' performance, and they can offer multifunctional features. Creating such high-performance nanocomposites via effective and mild approaches is an inevitable requirement for sustainable materials engineering. Nanocomposites, which combine two-star nanomaterials, namely, cellulose nanofibrils (CNFs) and graphene derivatives (GNMs), have recently revealed interesting physicochemical properties and excellent performance. Despite numerous studies on the production and application of such systems, there is still a lack of concise information on their practical uses. In this review, recent progress in the production, modification, properties, and emerging uses of CNFs/GNMs hybrid-based nanocomposites in various fields such as flexible energy harvesting and storage, sensors, adsorbents, packaging, and thermal management, among others, are comprehensively examined and described based on recent investigations. Nevertheless, numerous challenges and gaps need to be addressed to successfully introduce such nanomaterials in large-scale industrial applications. This review will certainly help readers understand the design approaches and potential applications of CNFs/GNMs hybrid-based nanocomposites for which new research directions in this emerging topic are discussed.

[Display omitted] • LOHC materials play a crucial role for H 2 dis/charging performance and reversibility. • Molecular engineering of commercial LOHC, DBT led to a novel LOHC material, BMB. • BMB outperforms DBT in de/hydrogenation performance. • Commercial DBT contains high-performing BMB under 27 %. • Engineered and sustainable synthetic method achieves high BMB ratio (>70 %). Liquid organic hydrogen carrier (LOHC) technology enables the safe, easy, and cost-effective storage and transportation of large quantities of hydrogen using inexpensive and mass-produced compounds. The LOHC materials play a crucial role in hydrogen storage capacity, reaction kinetics, reaction temperature, and reversibility. However, the development and optimization of LOHC materials is limited due to using of mass-produced materials for bulk hydrogen logistics. Herein, we propose a molecular engineering approach to overcome the limitations of commercial dibenzyltoluene (DBT)-based LOHC systems, considered one of the most promising LOHC materials based on the heat transfer oil, Marlotherm SH (MSH), owing to its superior physical properties (wide liquid range, and non-flammable properties), low price, and low toxicity. We devised a new chemical structure, benzyl-methylbenzyl-benzene (BMB), with highly improved dehydrogenation/hydrogenation performance achieved by rearranging the methyl group of DBT to overcome the limitations of slow reaction kinetics in terms of its chemical structure. The BMB exhibits a 150 % faster hydrogenation than MSH at 150 °C, and it releases 170 % more hydrogen compared to DBT at 270 °C. In addition, we analyzed the dehydrogenation/hydrogenation pathways according to the structures of DBT and BMB. Furthermore, we found that BMB (27 %) is inevitably generated in the MSH synthesis process alongside DBT (73 %).

This study investigates the performance of Pervious Concrete (PC) with varying quantities of Natural Coarse Aggregate (NCA) replaced by Waste Tire Rubber (WTR) (5%, 10% and 15% by weight) whereas Silica Fume (SF) (5%, 10% and 15%) and Fly Ash (FA) (10% constant) were employed as substitute for cement. This research aims at optimizing the mix of High Strength Rubberized Pervious Concrete (HSRPC) using Supplementary Cementitious Materials (SCMs), comparing experimental stress-strain graphs with the developed constitutive models and conducting a Life Cycle Assessment (LCA). Physical and mechanical performance of PC were examined using permeability and strength indices. X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) observed microstructural variations and Interfacial Transition Zone (ITZ) development. The use of WTR increased the permeability and decreased the strength indices. The permeability of mixes with 5, 10 and 15% WTR was found to be 4.00, 4.21 and 4.49 mm/s, which were more than control mix permeability. The compressive strength of PC with 5%, 10%, and 15% WTR was determined to be 32.48, 29.29, and 26.94 MPa, respectively, which were lower than control PC compressive strength which was 35.41 MPa. However, the addition of SF and FA enhanced the mechanical properties while causing a decrease in the permeability. Increasing SF content from 0% to 15% enhanced the compressive strength of PC containing 5% WTR, from 32.48 to 40.71 MPa. Developed constitutive models compared the stress-strain response of PC. Life cycle assessment showed that WTR, SF, and FA-based PC reduced the global warming.

Pharmaceutical active compound (PhAC) residues are considered an emerging micropollutant that enters the aquatic environment and causes harmful ecotoxicity. The significant sources of PhACs in the environment include the pharmaceutical industry, hospital streams, and agricultural wastes (animal husbandry). Recent investigations demonstrated that wastewater treatment plants (WWTPs) are an important source of PhACs discharging ecosystems. Several commonly reported that PhACs are detected in a range level from ng L−1 to μg L−1 concentration in WWTP effluents. These compounds can have acute and chronic adverse impacts on natural wildlife, including flora and fauna. The approaches for PhAC removals in WWTPs include bioremediation, adsorption (e.g., biochar, chitosan, and graphene), and advanced oxidation processes (AOPs). Overall, adsorption and AOPs can effectively remove PhACs from wastewater aided by oxidizing radicals. Heterogeneous photocatalysis has also proved to be a sustainable solution. Bioremediation approaches such as membrane bioreactors (MBRs), constructed wetlands (CWs), and microalgal-based systems were applied to minimize pharmaceutical pollution. Noteworthy, applying MBRs has illustrated high removal efficiencies of up to 99%, promising prospective future. However, WWTPs should be combined with advanced solutions, e.g., AOPs/photodegradation, microalgae–bacteria consortia, etc., to treat and minimize their accumulation. More effective and novel technologies (e.g., new generation bioremediation) for PhAC degradation must be investigated and specially designed for a low-cost and full-scale. Investigating green and eco-friendly PhACs with advantages, e.g., low persistence, no bioaccumulation, less or non-toxicity, and environmentally friendly, is also necessary. [Display omitted] • PhACs are found in the range from ng to μg L−1 concentration in WWTPs effluents • Pharmaceuticals have both acute and chronic harmful impacts • AOPs reach high effective removal of pharmaceuticals from wastewater owing to oxidizing radicals • The high removal efficiency of up to 99% and MBRs indicate prospective treatment • Microalgal-based technologies were applied to minimize pharmaceuticals effectively [ABSTRACT FROM AUTHOR]

The increased awareness of sustainability and concerns about global warming have prompted the construction industry to explore green sustainable materials such as geopolymer composites as an eco-friendly alternative to ordinary Portland cement (OPC). This study developed ambient-cured lightweight geopolymer composites (LWGPCs) by incorporating different volume fractions of expanded clay (EC). The physical and quasi-static characteristics of LWGPCs with various EC contents were investigated. Empirical formulae for the quasi-static compressive and splitting tensile strength, as well as the elastic modulus of LWGPCs were proposed. A Ø 100-mm split Hopkinson pressure bar (SHPB) system was employed to investigate the dynamic compressive and splitting tensile properties of LWGPCs. The failure processes and failure patterns of LWGPCs, as well as the stress–strain curves and the energy absorption capacities under different strain rates were compared. Based on the testing results, empirical formulae of the DIF (dynamic increase factor) for LWGPCs compressive and split tensile strength as well as the energy absorption capacities were proposed. This study offers valuable insights into the material performance of ambient-cured LWGPCs with EC as sustainable materials under quasi-static and dynamic loading, paving the way for further developing and application of lightweight and sustainable engineering materials in construction. • New ambient-cured geopolymer composites with expanded clay was developed. • Its physical and mechanical properties were investigated. • Its dynamic properties and energy absorption capacities were revealed. • Empirical formulae were proposed for dynamic properties and energy absorption.

[Display omitted] • Advanced bibliometric analysis of ionic liquids in lipase-catalyzed reactions literature. • China, USA, Spain, France lead in IL-lipase use. • The software VOSViewer, CiteSpace, ArcMap, Excel and Google Sheets were used for analysis. • Analysis of the most used ionic liquids in recent years and their applications. • Ionic liquids and enzymes replace harmful chemicals with eco-friendly methods. Ionic liquids (ILs) are widely used in many applications. Still, their use in enzyme engineering is particularly notable due to their environmentally friendly nature and efficient replacement of conventional organic solvents. Recently, lipase has emerged as an environmentally friendly catalyst. Nevertheless, using Lipases in the presence of ILs has led to a remarkable activity enhancement, making it a sustainable and non-harmful approach. This study conducted a bibliometric review of research articles published between 2010 and 2022 concerning the use of ILs in lipase-catalyzed reactions. The analysis was based on 206 publications retrieved from the Web of Science Core Collection (WoS) database., which were analyzed using different software tools, such as VOSviewer, CiteSpace, and ArcGIS. Key findings included that over half of the publications originated from other countries, notably China (around 36.4%), the United States, Spain, and France. As a result of this bibliometric analysis, four emerging trends were identified: namely: i) lipase-catalyzed synthesis, ii) the use of deep eutectic solvent, iii) the application of ILs in secondary alcohol reactions, iv) the use of ILs as green solvents, and iv) the enzymatic ring-opening polymerization. The study also evaluated the most prominent authors, articles, and institutions that provide comprehensive data on up-to-date research on ILs and lipases. It is noted that the studies identify significant advantages in this field, showing a positive trend of promising results, especially with the development of improved and environmentally friendly processes.

This study characterizes the spatio-temporal wave variability along Southwestern Nigerian coastal and shelf areas in the Gulf of Guinea. This is to provide further insight into the hydrodynamic factors that influence geomorphologic changes on the low-lying coast. Reanalysis wind-field datasets are employed to generate hourly wind forcing for an unstructured WAVEWATCH III model to simulate some bulk wave parameters. The model is validated against data from offshore buoys and satellite altimetry at selected locations near the coast. Results show that the waves have an annual average of significant wave height (H s), peak period (T p), and wind speed (u) of ∼0.5 m, 4.1 s, and 3.9 m/s, respectively. They exhibit seasonal spatial variability that is highest in the peak rainy season from July to September (Av. H s : 0.56–0.79 m; Av. T p : 4.68–5.18 s; Av. u : 4.30–5.22 m/s) and lowest in the early dry season from November to January (Av. H s : 0.26–0.34 m; Av. T p : 3.37–3.80 s; Av. u : 3.25–3.50 m/s). Also, the monthly averaged wave power varies from 0.2 to 2.8 kW/m annually. However, a maximum H s of 2.2 m that generated power of 9.4 kW/m for 11.1 s was recorded during the peak of the rainy season in August. Overall, waves with relatively low intensity, which can be classified as smooth to moderate, propagate from the southwest direction and decrease towards the coast. The higher H s and T p recorded during the peak of rainy and end of dry seasons are attributed to the influence of far-away swells. A comparative assessment indicates that the Barrier-Lagoon coast is highly controlled by waves, while the Mahin mud coast, which witnesses frequent flooding events that degrade its shoreline, has little wave influence. Thus, local subsidence that increases the relative sea level is suggested to be taking place at sections of the muddy coast. This information is crucial for the sustainable engineering design and management of low-lying coasts. • The SW Nigerian coastal and shelf area is characterized by smooth to moderate waves. • The waves exhibit seasonal variations that are strongest at the peak of rainy seasons. • The Barrier-Lagoon shelf has relatively stronger waves that can be harnessed. • Complex hydrodynamic interactions control geomorphological changes in the area. • Mahin coastal degradation is aggravated by alterations in local geomorphology.

The increasing role of biocatalysis in the green and sustainable manufacture of chemicals is discussed. In the last two decades the breadth and scope of biocatalysis has increased enormously as a result of remarkable advances in metagenomics, protein engineering and bioinformatics. Moreover, the use of enzymes has become more cost-effective through advances in immobilization technologies and the application of the immobilized enzymes in continuous flow operation in packed bed reactors. Consequently, biocatalysis is already the method of choice for the synthesis of enantiopure chiral products for the pharmaceutical and fine chemical industries. Further applications in commodity chemicals manufacture are currently being stimulated by the increasing maturity of biocatalysis and the ongoing transition to a bio-based circular economy based on the valorization of organic waste on the road to net zero manufacturing. • Biocatalysis is green and sustainable. • Biocatalysis is the method of choice for producing enantiomerically pure products. • Biocatalysis the appropriatetechnology for waste valorization. • Biocatalysis is an ideal tool for a circular bio-based economy. • Biocatalysis shows the way on the road to net zero.

A teaching approach of programming experiment courses with a new education process is proposed in this study to improve the sustainability of engineering education and extend the accessibility of lab experiments across experiment courses, with the goal of encouraging innovative and scientific thinking among students. The Millikan Oil-Drop experiment combined with Java object-oriented programming is demonstrated as a case study to validate the feasibility and advantages of this teaching approach. The new education process of the experiment course is designed based on Jean Piaget's cognitive development theory, which has high practical potential for popularization among tertiary institutions without additional cost. Additionally, this work discussed the relevance of the general criterion of the Accreditation Board for Engineering and Technology on student outcomes to educational accreditation, further indicating that introducing programming into experiment education can improve students' all-round ability and strengthen the triangular relationship among the three main subjects in tertiary education, namely, students, faculty, and higher educational institutions. This study may serve as an educational guide for teachers and tertiary institutions to pursue innovative and sustainable education. [Display omitted] • Introducing programming to course can enhance sustainability for education. • Programming can help students facilitate the data-processing of experiments. • Introducing programming can better ignite students' interest in the course. • The innovation-oriented approach can help improve the teaching quality. • The approach can make for clean production and sustainable development.

This article reassesses the concept of a house from a non-human perspective. The two worlds that collide in this article are philosophical analyses that are "beyond the human" and sustainable engineering house design. By analyzing the houses of ten animal species for shelter/skin properties, life pedagogy (how to live), materials and resources, thermal dynamics, and structural elements, we speculate on the future of housing. The premise of this article is that "beyond the human" philosophy opens a new visage to comprehend and conceptualize what a house could be. Beyond the human theorizing is defined by philosophy that has gone beyond framing an exploration internally to the benefit of themselves, as human subject(s). This article speculates that considering animal house construction is a way forward for thought in a changing climate. [ABSTRACT FROM AUTHOR]

Industrial ecology and sustainability education have evolved over time, as this relatively new discipline has emerged and has been refined. Courses engaging with these topics are often found in engineering departments, and feature project or problem‐based learning (PBL) commonly with an industrial partner. This provides students the opportunity to apply the topics that they have learned in class in a real‐world situation, complete with the constraints and uncertainties inherent in practice. Community‐based learning (CBL), a combination of service learning and PBL, allows students to not only apply the material from a sustainability course, but also to do so in service of a community partner. This work presents an analysis of a multi‐year effort in teaching a CBL course on the topic of industrial ecology and sustainability in a North American context. Knowledge probes are utilized to quantify student preparation for the course and confidence in knowledge gained during the course in a longitudinal manner. Meanwhile, evolving student reflection is utilized to assess the impact of how the CBL element of the course influenced student thinking about the role of sustainability and industrial ecology within engineering education. The findings suggest that applying CBL to industrial ecology education has the potential to further enhance student learning experiences, while also providing a valuable service experience.

Perovskite light‐emitting diodes (PeLEDs) have garnered considerable interest in recent years owing to their unique optoelectronic properties. However, the performance of PeLEDs is limited by their low quantum efficiency and unbalanced charge injection. In this study, to address these issues, a novel co‐hole transport layer (HTL) of 4,4′‐bis(N‐carbazolyl)‐1,1′‐biphenyl (CBP) and poly(9‐vinylcarbazole) (PVK) is introduced into PeLEDs. By optimizing the composition ratio of CBP and PVK, the performance of CsPbBr3‐based PeLEDs is significantly improved via efficient Förster resonant energy transfer and an enhanced charge transfer owing to the well‐aligned energy levels of the HTLs with the emission layers. The PeLED with an optimized composition ratio of the PVK0.5–CBP0.5 HTL exhibits the best device performance with a luminance of 31641 cd∙m−2, current efficiency of 39.2 cd∙A−1, and external quantum efficiency of 15.4%. Thus, the proposed strategy engineering dual transfer of energy and charge is expected to be revolutionary in the field of PeLED research. [ABSTRACT FROM AUTHOR]

Household water insecurity (HWI) can have far‐reaching consequences for human health and well‐being, yet little is known about how environmental seasonality contributes to HWI variation. Using a systematic literature review, we examined the following questions: (1) How does environmental seasonality affect HWI? and (2) How do the effects vary over time? We also highlighted strategic areas for future research. We conducted the search using Scopus, Web of Science, PubMed, ProQuest, and EBSCO Academic Search Complete, with an end search date of February 3, 2021; only English‐language studies were included. Articles were included in the review if analysis studied seasonal temperature, precipitation, or freshwater variation and individual or household experiences with household water adequacy, water reliability, water affordability, or water safety. Bias was evaluated via hand assessment, and articles of poor quality were excluded. Studies that focused on extreme weather events or water insecurity at community or watershed levels were omitted. We identified 67 articles, the majority of which were cross‐sectional (n = 46, 68.7%). Among longitudinal studies (n = 21, 31.3%), only one used a quantitative HWI scale, while the rest relied on proxies (n = 20, 95.2%). Our review also revealed literature gaps related to unequal coverage of freshwater ecosystem habitat types and forms of environmental seasonality. There is a need for more attention to extreme climate events, such as a prolonged multiyear drought. With changing climate expected to exacerbate weather patterns with serious implications, especially for vulnerable populations, understanding seasonality in HWI is important for crafting sustainable engineering and policy responses to water insecurity.
