Screen printing enables the production of very thin magnetic sheet laminations in near net shape geometry. This minimizes material waste in production and simultaneously reduces losses during machine operation and in-creases geometric design freedom. The subsequent sintering process step is particularly relevant, since the geometrical and magnetic properties are defined, and relevant process costs are caused by the heat treatment. This paper presents the requirements of the debinding and sintering process for magnetic sheets and identifies relevant influencing factors to achieve defined product specifications in multiple iterations, using design of experiments. It focuses on the influencing factors furnace atmosphere, sintering temperature, holding time and stacking height and their impact on the magnetic and geometric properties of sintered magnetic sheets.

AbstractField effect transistors (FETs)-based detection probes are powerful platforms for quantification in biological media due to their sensitivity, ease of miniaturization, and ability to function in biological media. Especially, FET-based platforms have been utilized as promising probes for label-free detections with the potential for use in real-time monitoring. The integration of new materials in the FET-based probe enhances the analytical performance of the developed probes by increasing the active surface area, rejecting interfering agents, and providing the possibility for surface modification. Furthermore, the use of new materials eliminates the need for traditional labeling techniques, providing rapid and cost-effective detection of biological analytes. This review discusses the application of materials in the development of FET-based label-free systems for point-of-care (POC) analysis of different biomedical analytes from 2018 to 2024. The mechanism of action of the reported probes is discussed, as well as their pros and cons were also investigated. Also, the possible challenges and potential for the fabrication of commercial devices or methods for use in clinics were discussed. [ABSTRACT FROM AUTHOR]

Nanozymes represent a novel class of artificial enzymes and biocatalysts, possessing both the physical and chemical properties of nanomaterials along with unique enzyme-like catalytic activities, which breaks the boundary between inorganic materials and organic life. Unlike natural enzymes, traditional enzyme mimics and chemical catalysts, nanozymes exhibit catalytic activity that can be regulated by their nanoscale physical and chemical properties. They are characterized by good stability, high- and lowtemperature resistance, acid and alkali resistance, adjustable activity, and multifunctionality. As a result, nanozymes have garnered widespread attention in the fields of biomedicine, environment treatment, green agriculture, new energy resources, and have begun to establish a disciplinary framework. This review aims to provide an overview of the discovery, disciplinary characteristics, and framework of nanozymes, as well as their applications and future development prospects, in order to advance our understanding and promote further development in this field.

In the current context regarding energy sources’ problems, it is estimated that a high percentage of waste will be produced from photovoltaic panels, that will put pressure on the environment. Thus, the study focuses on downcycling them by incorporating them into mortars by six new recipes (R1, R2, R3, R4, R5 and R6) that replace the sand by integrating photovoltaic panels’ dust (PVd) and pieces of photovoltaic panels (PVp) (1/3 to 100% of the total amount). All samples were subjected to tensile bending, compression and an economic analysis and were compared with the control sample (R0). As a result of the experimental research, a change in the apparent density of the proposed samples was found, and a general improvement in all areas of testing. The obtained results show that used photovoltaic panels can constitute raw material for the creation of new construction materials. [ABSTRACT FROM AUTHOR]

Electrical machines play a major role in achieving a more sustainable economy by driving the further electrification of industry and transportation. To enhance the electric motor productivity during production and the efficiency during operation, it is essential to maximize the material yield rate during the production of stator and rotor sheet stacks and reduce iron losses during operation. Screen-printing technology can help to achieve these goals by producing thin magnetic sheet laminations in near-net-shape geometry, resulting in minimum material waste during production. Moreover, reducing the sheet thickness decreases the eddy current losses and avoids mechanical stress during manufacturing, leading to improved motor efficiency. Additionally, screen printing facilitates the production of multi-material components and variable alloy compositions. This study aims to identify the relevant factors and printing parameters so that screen-printed magnetic sheets can achieve product specifications. A method involving the statistical design of experiments is performed in several iterations to investigate the target parameters of the print cycle time, green part weight, shape integrity and layer thickness, and to analyze the main interdependencies. The results of this study provide valuable insights into optimizing the screen-printing process for soft magnetic sheets, enabling the production of efficient electric motors while reducing material scrap.

Since the 1980s, research on Sinographic literature has made significant strides. From the standpoint of academic history, this research has undergone three broad stages, which are represented respectively by new materials, new questions, and new methods. These have been the overall trends, which necessarily overlap each other. Research on Sinographic literature has diverged from a focus on new material toward the refinement of new questions and the exploration of new methodologies. One such exploratory approach is "the Sinosphere as methodology," which addresses the shortcomings of four previous research models and seeks to put this new methodological concept into practice, to contain the expansionist impulses of cultural imperialism, and to prise apart nationalist parochialism.

Here, a new class of high-performance composites, called "Lightweight Flexible Nonlinear Composites (LFNLC)", has been briefly introduced. This class of composites has its own structural and functional characteristics as Nonlinear behavior in bending and porous or porous-like texture. - Cementitious LFNLC is termed "Elastic Composite, Reinforced Lightweight Concrete (ECRLC)". The ECRLC provides lightweight beams with substantial strain capability, resilience modulus and toughness in bending, resulting in a considerable increase in bearing capacity while weighing significantly less. The failure mode in low-height and ultra-lightweight beams made of the ECRLC is not compressive and brittle. - This lightweight, flexible composite is a non-monopolistic, versatile and comparatively low-price material. Likewise, the virtues such as resilience and flexibility, workability, lightness, durability, and high formability are important in architecture. - In general, lightweight and integrated construction has a key importance in earthquake resistance. Therefore, the ECRLC can be especially beneficial in earthquake-prone regions. - Considering the flexibility and resilience of this formable system, it can also be used to build non-brittle reinforced ultra-lightweight and insulation sandwich panels, safe and lightweight guards, and shock-resistant structures. Likewise, they are utilizable in some infrastructures and explosion-proof pieces with suitable behavior, resilience, and toughness. - This work presents a practical method for converting a rigid solid into a flexible material with lower density or increasing the elasticity of a flexible material while decreasing the density. Essentially, this method entails creating a porous or porous-like texture in the material, reinforcing appropriately, and providing it with the necessary integrity. (For example, properly dispersing lightweight aggregates all over the reinforced, conjoined matrix can produce a porous-like texture.) By this process, the resilience modulus and toughness in bending rise and the density reduces. - This paper briefly discusses the functional and structural characteristics of LFNLCs, some applications, and Reproducible examples of the ECRLC.

Materials with magnetic properties are essential in various electric sector technologies. However, the generation of pollutants is of concern, increasing the interest in developing new sustainable, low-cost magnetic materials. These materials have notable applications in protecting against electromagnetic interference (EMI), which can lead to health problems as well as environmental pollution. Therefore, the aims of the present study were to produce a sustainable magnetic polymer using different methods of magnetite incorporation, investigate its magnetic properties, and determine its EMI shielding potential. The magnetic BC materials were obtained via in situ and ex situ magnetic incorporation in processed BC membranes and BC hydrogels. Analyses were carried out using XRD, FTIR, SEM, and VSM, and tests were performed to assess electromagnetic interference shielding effectiveness (EMI SE). The results revealed that the magnetite incorporation method influences the final size of nanoparticles, the arrangement among BC fibers, and the magnetic properties. Materials produced from processed BC had a higher percentage of incorporated magnetite and greater magnetic saturation, whereas those containing nanoparticles with a larger diameter had a stronger coercive field. Although samples did not have high EMI SE, magnetite increased the wave reflection and absorption of the material. This biomaterial can drive important innovations in the energy sector, particularly in efficient and ecological electrical infrastructure.

The rapid development of key technologies for the intelligent research and development (R&D) of new materials has significantly promoted the R&D efficiency and industrialization of materials and attracted global attention. China’s development in this field lags behind the advanced international level in terms of key technologies and infrastructures, which has restricted the original innovation and industrial development of the material sector. This study summarizes the key technologies involving the intelligent R&D of new materials, explores the developing status of these key technologies in China and abroad, and analyzes the challenges faced by China. Moreover, the intelligent R&D technology system is summarized including intelligent computing and design technologies and software, autonomous/intelligent experiment technologies and equipment, artificial-intelligence-driven basic algorithms and technologies, digital twins, intelligent R&D platforms and collaborative innovation networks. Furthermore,countermeasures are proposed from the aspects of innovative ecology construction, industrial environment improvement, standards system establishment, talent training, and international cooperation.

With the rapid development of world’s technological level and the urgent demand of national economic construction for high-performance alloy materials, traditional single-component alloys gradually fail to satisfy the increasing service requirements. Owing to their unique physical, chemical, and mechanical properties, high-entropy alloys are expected to play an important role in major engineering fields such as national defense, aviation, aerospace, marine, nuclear energy, medical care, and new energy, greatly expanding the design range of metal material compositions. In this paper, based on the specific demands of advanced high-entropy alloy materials in various fields, the characteristics and connotations of high-entropy alloy materials are summarized, and the overall situation and prospects of high-entropy alloy material development are analyzed, as well as the current status of high-entropy alloy development in China and abroad. On this basis, the gaps and deficiencies in the field of high-entropy alloys in China are pointed out. First, some basic raw materials of the high-entropy alloys still rely on imports, which severely threatens the security of the industrial chain. Second, the research and development investment in industrial application of high-entropy alloys needs to be increased, and the industrial–academia–research–application system of high-entropy alloys is not yet sound. Regarding the above-mentioned issues, this study proposes the following policies and measures: strengthening the top-level design of high-entropy alloy material research and development while improving industrial policies; strengthening the connection and communication between enterprises and research institutes; improving the standardization, testing, characterization, and evaluation systems of high-entropy alloy materials; advancing the construction of talent teams; and reducing material costs and creating high value-added products, to promote the systematic, green, high-end, and intelligent development of China’s advanced high-entropy alloy material industry.

Food analysis is critical for ensuring human health and safety, as it involves the detection of contaminants such as pesticides, heavy metals, mycotoxins, allergens, and microbial contaminants. Effective extraction and pre-concentration of these analytes are crucial to achieve accurate analysis and comply with regulatory standards. However, food matrices are complex, including solid, semi-solid, and liquid components, fats, proteins, carbohydrates, vitamins, minerals, and other organic and inorganic compounds. Therefore, isolation of target analytes is a challenging task. Developing efficient sample preparation techniques is essential to overcome such a downside. Exploring new and improved sorbent materials is one of the advanced strategies for developing selective and greener sample preparation approaches. Cyclodextrins (CDs) play a significant role in this topic. CDs can interact with various compounds with their external hydrophilic structure and central hydrophobic cavity. The functionalization of CDs' external hydroxyl groups allows for modifications in solubility, cavity opening, and bonding with other sorbent materials. This review discusses the current status of CDs as a robust sorbent material in food- and nutraceutical analysis. It covers the principles of CD-based sorbent preparation. It explores combining them with other materials, creating customized sorbents for solid-phase extraction techniques, including dispersive, packed devices-based, and coated devices-based methods. Moreover, we offer insights into relevant applications focusing on food surveillance and nutraceutical analysis.

This article reports a new approach toward fabrication and directed assembly of nanoparticulate reactive system (Nanofoils) on patterned substrates. Different from current state‐of‐the‐art, gas phase electrodeposition uses nanoparticles instead of atoms to form densely packed multilayered thin films at room temperature‐pressure. On ignition, the multilayer system undergoes an exothermic self‐propagating reaction. The numerous contact points between two metallic nanoparticulate layers aid in high heat release. Sub‐10‐nm Platinum (Pt) and Aluminum (Al) particles are synthesized through cathode erosion of metal electrodes in a flow of pure nitrogen gas (spark ablation). Pt/Al bilayer stacks with total thickness of 3–8 µm undergo self‐propagating reaction with a 10.3 mm s−1 wavefront velocity on local ignition. The reaction wavefront is captured using high speed videography. Calorimetry studies reveal two exothermic peaks suggesting Pt/Al alloy formation. The peak at 135 °C has a higher calorific value of 150 mW g−1 while the peak at 400 °C has a 12 mW g−1 exothermic peak. X‐ray diffraction study shows reaction‐products are cubic Al2Pt with small quantities of orthorhombic Al6Pt and orthorhombic AlPt2. Electron microscopy studies help draw a correlation between film morphology, bimetallic interface, nanoparticle oxidation, and self‐propagating reaction kinetics that is significant in broadening our understanding towards nanoparticulate reactive systems.

Bionic skin can simulate human skin with the ability to perceive a variety of stimuli, and has a wide range of applications in medical monitoring, artificial intelligence and other fields. However, traditional electronic skin materials usually have problems such as low mechanical strength, poor adhesion performance, and loss of facility due to easy water loss, which limits its application in the field of electronics. In this paper, a polymer of dopamine-modified carboxymethyl cellulose (CMC-DA) was prepared based on mussel adhesin and sodium carboxymethyl cellulose, a derivative of natural polymer cellulose, and introduced into a zwitterion polycarboxybetaine (PCB) hydrogel. When the substitution degree of CMC-DA catechol group as 6.8%, CD- PCB hydrogel has good adhesion performance, and can be adjusted by different CMC-DA substitution degrees. The mechanical properties of the hydrogel are greatly improved. On this bass, natural polymer material silk protein s added to enhance the moisturizing performance of hydrogel. CDP-SILK hydroids are ate bacteriostatic, and obtain good electrical conductivity under the penetrating network of metal ions. In general, the material has developed a well-biocompatible zwitterion biomimetic skin, which has high moisturizing, high adhesion, good biodescriptablity and high electrical conductivity, showing good prospects for flexible wearable devices in bioelectronics applications.

In order to solve the global problem of bridge head jumping caused by the insufficient compaction of the roadbed in the transition section of highways and bridges, a desulfurization gypsum–fly ash flowable lightweight soil without vibration, capable of self-compaction, low bulk density, and economic and environmental protection, has been developed. This study selected low-grade cement, industrial waste (fly ash and desulfurization gypsum), and Yellow River silt as the raw materials for the design of the mix ratio of a desulfurization gypsum–fly ash flow-state lightweight soil mix. Through multiple indoor experiments, the influence of cement content, silt content, and the fly ash/desulfurization gypsum quality ratio on its fluidity and mechanical properties was systematically studied. The stress–strain relationship under uniaxial compression was analyzed and the strength formation mechanism was revealed through scanning electron microscopy (SEM). The results show that the mechanical properties of the prepared desulfurization gypsum–fly ash flowable lightweight soil meet the engineering requirements. Increasing both the cement and fly ash content results in the decreased fluidity of the desulfurization gypsum and fluidized fly ash. However, as the mass ratio of fly ash to desulfurization gypsum increases, the fluidity reaches its maximum when the mass ratio of fly ash to desulfurization gypsum is 2:1. Based on the stress–strain relationship test results, a uniaxial compressive constitutive model of the desulfurization gypsum–fly ash flowable lightweight soil was proposed. The model was fitted and analyzed with the test results, and the correlation was greater than 0.96. The high degree of agreement showed that desulfurization gypsum can promote the disintegration of fly ash, thereby increasing the specific surface area. This provides more contact points, promotes the hardening process, and enhances the interlocking force between particles and the formation of cementitious substances, further enhancing strength.

Iron oxide nanoparticles have been investigated due to their suitable characteristics for diverse applications in the fields of biomedicine, electronics, water or wastewater treatment and sensors. Maghemite, magnetite and hematite are the most widely studied iron oxide particles and have ferrimagnetic characteristics. When very small, however, these particles have superparamagnetic properties and are called superparamagnetic iron oxide nanoparticles (SPIONs). Several methods are used for the production of these particles, such as coprecipitation, thermal decomposition and microemulsion. However, the variables of the different types of synthesis must be assessed to achieve greater control over the particles produced. In some studies, it is possible to compare the influence of variations in the factors for production with each of these methods. Thus, researchers use different adaptations of synthesis based on each objective and type of application. With coprecipitation, it is possible to obtain smaller, more uniform particles with adjustments in temperature, pH and the types of reagents used in the process. With thermal decomposition, greater control is needed over the time, temperature and proportion of surfactants and organic and aqueous phases in order to produce smaller particles and a narrower size distribution. With the microemulsion process, the control of the confinement of the micelles formed during synthesis through the proportions of surfactant and oil makes the final particles smaller and less dispersed. These nanoparticles can be used as additives for the creation of new materials, such as magnetic bacterial cellulose, which has different innovative applications. Composites that have SPIONs, which are produced with greater rigour with regards to their size and distribution, have superparamagnetic properties and can be used in medical applications, whereas materials containing larger particles have ferromagnetic applications. To arrive at a particular particle with specific characteristics, researchers must be attentive to both the mechanism selected and the production variables to ensure greater quality and control of the materials produced.

Methods for preparation of solid solutions (hetero- and homosubstituted) in the systems InP‒CdTe and CdS–CdTe have been worked out. The prepared solid solutions have been attested, on the basis of the X-ray diffraction, microscopic, electron microscopic, and optical studies results, as the substituted solid solutions with the structure of sphalerite and wurtzite, respectively; average dimensions (dav) and average numbers (nav) for the most representative particles of components and values of the band gap (ΔE) for the solid solutions have been determined. Acid–base properties of the surfaces for the systems components have been studied; their weak acidic character at relatively increased acidity of the solid solution surfaces of the InP–CdTe system has been demonstrated. Dependences of the volume and surface properties on the composition have been established. The found similarity and differences in behavior of the systems solid solutions have been explained by predominant influence of either the common component (CdTe) or the components (InP, CdS) differing in values of the band gap, difference in electronegativities difference, and ionic bonding contribution. Considerations concerning the possibilities of looking for new adsorbents—materials for semiconducting gas analysis—have been proposed. [ABSTRACT FROM AUTHOR]

The chemical composition of the surfaces of solid solutions and binary components of the InP‒ZnS system exposed in air and after thermal and vacuum treatment has been studied using the IR MDTIR spectroscopy method. The acid–base properties of the surfaces for the components of the system assigned to the weak acidic area (pHiso < 7) have been studied by the methods of hydrolytic adsorption, nonaqueous conductometric titration, and mechanochemistry. The possibility of application of the prepared materials for manufacturing sensors for the impurities of basic gases has been demonstrated. A conclusion concerning the nature of active centers and mechanisms of acid–base interactions has been derived. Predominantly statistical regularities in the composition dependences of the acid–base properties have been found. Influence of the degree of difference in the basic volumetric properties, in particular, band gap (ΔE) for the initial binary compounds (InP, ZnS), has been confirmed. On the basis of the derived correlation between regularities in variation of surface and volumetric properties, a less labor-consuming and expensive direction based on the known volumetric properties for searching for new materials for sensory technology has been substantiated. Practical patented recommendations for application of the prepared materials in sensory technology have been given and realized. [ABSTRACT FROM AUTHOR]

The structures and mechanical properties of a new alloyed (0.2 wt % Ag and 0.5 wt % Ti) corrosion-resistant steel 03Kh17N10M2 (0.023 C–17 Cr–10 Ni) were studied. The structure was studied by light optical microscopy and X-ray diffractometry. The mechanical properties were studied by stretching the samples on a tensile testing machine according to GOST 1497-84. The effect of homogenizing annealing and ingot rolling on the structure of alloyed corrosion-resistant steel is shown. Plates after rolling have a fine-grained structure. Normalization at 900°C and 1000°C reduces the proportion of ferrite in the structure, reduces the anisotropy of mechanical properties, and increases the steel ductility. [ABSTRACT FROM AUTHOR]

Existing commercial powders for laser additive manufacturing (LAM) are designed for traditional manufacturing methods requiring post heat treatments (PHT). LAM's unique cyclic thermal history induces intrinsic heat treatment (IHT) on materials during deposition, which offers an opportunity to develop LAM‐customized new materials. This work customized a novel Fe–Ni–Ti–Al maraging steel assisted by machine learning to leverage the IHT effect for in situ forming massive precipitates during LAM without PHT. Fast precipitation kinetics in steel, tailored intermittent deposition strategy, and the IHT effect facilitate the in situ Ni3Ti precipitation in the martensitic matrix via heterogeneous nucleation on high‐density dislocations. The as‐built steel achieves a tensile strength of 1538 MPa and a uniform elongation of 8.1%, which is superior to a wide range of as‐LAM‐processed high‐strength steel. In the current mainstream ex situ 4D printing, the time‐dependent evolutions (i.e., property or functionality changes) of a 3D printed structure occur after part formation. This work highlights in situ 4D printing via the synchronous integration of time‐dependent precipitation hardening with 3D geometry shaping, which shows high energy efficiency and sustainability. The findings provide insight into developing LAM‐customized materials by understanding and utilizing the IHT‐materials interaction. [ABSTRACT FROM AUTHOR]

In this paper, we focus on optimizing the solar performance of a CZTSSe-based solar cell by adjusting the zinc and sulfur concentrations in the CdZnS buffer layer and the quinary absorber CZTSSe. The state-of-the-art work is to combine the ZnS and CdS binaries into CdZnS ternary used as a buffer layer in both CZTS- and CZTSSe-based solar cells. An overall study of its properties is carried out taking into account the strain present at the heterointerface, defect density, bandgap energy and the interface state density. As a result, the highest efficiency η = 14.59% was achieved with a sulfur content of 0.55 and a zinc content of 0.70 to bandgap energies of 1.25 and 3.12 eV for CZTSSe and CdZnS materials, respectively. Our simulation is validated by the reproducibility of solar cell performance under the same conditions, and an enhancement of the conversion efficiency of about Δη = 5.55% will be achieved when the CdS layer is replaced by CdZnS in the ZnO/CdS/CZTSSe/Mo/Glass solar device.

The findings provide insight into developing LAM‐customized materials by understanding and utilizing the IHT‐materials interaction.

Electrical machines play a major role in achieving a more sustainable economy by driving the further electrification of industry and transportation. To enhance the electric motor productivity during production and the efficiency during operation, it is essential to maximize the material yield rate during the production of stator and rotor sheet stacks and reduce iron losses during operation. Screen-printing technology can help to achieve these goals by producing thin magnetic sheet laminations in near-net-shape geometry, resulting in minimum material waste during production. Moreover, reducing the sheet thickness decreases the eddy current losses and avoids mechanical stress during manufacturing, leading to improved motor efficiency. Additionally, screen printing facilitates the production of multi-material components and variable alloy compositions. This study aims to identify the relevant factors and printing parameters so that screen-printed magnetic sheets can achieve product specifications. A method involving the statistical design of experiments is performed in several iterations to investigate the target parameters of the print cycle time, green part weight, shape integrity and layer thickness, and to analyze the main interdependencies. The results of this study provide valuable insights into optimizing the screen-printing process for soft magnetic sheets, enabling the production of efficient electric motors while reducing material scrap.
