Packaging waste makes up more than 10% of the landfilled waste in the United States. While consumers often want to make environmentally friendly product choices, we find that their perceptions of the environmental friendliness of product packaging may systematically deviate from its objective environmental friendliness. Eight studies (N = 4,103) document the perceived environmental friendliness (PEF) bias whereby consumers judge plastic packaging with additional paper to be more environmentally friendly than identical plastic packaging without the paper. The PEF bias is driven by consumers' "paper = good, plastic = bad" beliefs and by proportional reasoning, wherein packaging with a greater paper-to-plastic proportion is judged as more environmentally friendly. We further show that the PEF bias impacts consumers' willingness to pay and product choice. Importantly, this bias can be mitigated by a "minimal packaging sticker" intervention, which increases the environmental friendliness perceptions of plastic-only packaging, rendering plastic-packaged products to be preferable to their plastic-plus-paper-packaged counterparts. This research contributes to the packaging literature in marketing and to research on sustainability while offering practical implications for managers and public policy officials.

The production of paper–polymer composite materials based on polystyrene and plant extracts of coniferous trees is described. The resulting bioplastics have increased resistance to biodegradation and are a promising basis for use as reinforcing polymer systems of cellulose-containing materials used for the production of packaging materials and special-purpose papers as part of electrical devices for various purposes. It has been shown that the inclusion of plant extracts makes it possible to improve the physical and mechanical properties of paper composites and ensure their resistance to biocorrosion. The conducted research makes it possible to expand the areas of application of paper materials and products based on them. [ABSTRACT FROM AUTHOR]

Cellulosic material is considered to be excellent for food packaging due to its low cost, easy degradability, and high recyclability rates. However, its application is still limited due to its porous structure and high hydrophilicity, which provide high permeabilities to grease, gas and water vapor. One solution to fix these issues and to bring new functionalities that can also extend food shelf life is to coat the paper substrate with biopolymers containing nanoparticles and/or components with antioxidant and/or antimicrobial activities. In this regard, the aim of this study was to review some aspects of the current knowledge critically and didactically on applications of biopolymer-based coatings incorporated with active components and/or nanoparticles on paper/paperboard materials usually applied as primary cellulosic active packaging. Studies have shown that this combination can positively improve the physical, mechanical, and barrier properties of cellulosic packaging, along with the enhancement of antioxidant and antimicrobial activities. A better understanding of these aspects enables the use of other active compounds to develop more functionality to the packaging itself as well as to apply it to food packaging in general.

The article provides a history of Renaissance cartapesta or papier mâaché and explores its use in 15th- and 16th-century Italy and Germany. Topics discussed include earlier Italian recipe for cartapesta, Don Alessio Piemontese's cartapesta recipe collection, papier mâaché recipe in a female convent in Nuremberg, Germany, papier mâaché reliefs at the Cistercian monastery of Wienhausen and papier mâaché production in the context of the Lutheran Reformation.

In the late 18th and first half of the 19th century, print gained a permanent foothold in the Middle East and enabled the mass production of books in Arabic, Turkish, and Persian. As a consequence, handwriting gradually ceased to be the primary technology for making books. This article, the second of two, examines the materiality of a selection of Arabic manuscripts mostly made between 1870 and 1930 CE. It shows how scribes not only adapted to the availability of new types of pens or stationery when making their manuscripts, but also that some of them adopted layout choices and paracontent typical of printed books. Tradition and change are both visible in the objects that were analysed, and it is especially against the backdrop of a growing print industry in the Middle East that Arabic manuscript culture's strengths and its ability to adapt emerge.

In the realm of food waste recycling, industrial suberoligneous by‐products like cork and peels, pose a challenge for value‐added conversion, primarily due to their intricate structures. This study introduces an innovative approach by utilizing recycled cork as a prime example of repurposing food waste to create a reusable and durable packaging paper. Notably, the manufacturing process of this cork‐based paper avoids the generation of waste liquids from lignin removal, effectively alleviating concerns related to liquid waste pollution. The resulting packaging paper demonstrates remarkable printability, readability, and erasability while offering reusability. Its performance can be fine‐tuned through pH value adjustments. Moreover, this packaging paper exhibits outstanding antioxidative properties and barrier properties, seamlessly integrating superb UV‐blocking proficiency and heightened visible transparency, rendering it highly appealing for sustainable food packaging applications.

Excessive copper (Cu2+) causes adverse effects on human health and the ecological environment. Traditional methods for detecting Cu2+ have drawbacks such as high detection costs, complex operating conditions, and being time consuming. Therefore, there is an urgent need to develop simple detection methods to better meet specific health and environment quality needs. In this work, a paper-based fluorescence sensor was prepared (herein referred to as the as-prepared method) by immersing filter paper in aqueous polyethyleneimine (PEI) solution, and its potential use in Cu2+ detection was investigated. The results showed that the as-prepared paper samples, with fluorescence properties obtained by aggregation-induced luminescence of PEI, have selective recognition of Cu2+ based on the internal filtration effect, and the lowest detection limit is 0.03 μM. In addition, the relative error of this method is in the range of 1.80~2.23%, which is relatively comparable to the national standard method (0.63~630 μM), demonstrating high accuracy. Therefore, paper-based sensors with a simple preparation method have potential applications in the detection of Cu2+ in water. [ABSTRACT FROM AUTHOR]

The fines fraction in mechanical pulp, produced during wood processing can impact the mechanical properties of the resulting paper positively or negatively, making them potential additives for paper strength improvement at the right loading level. To enhance fines' effectiveness as paper strength additives that have heterogeneous surface chemistries, this work employed a regioselective surface esterification method conducted under mild conditions in acetone, with the addition of succinic anhydride and imidazole. This approach converted surface hydroxyl groups of fines into carboxylic acid groups, resulting in a final content of near 0.5 mmol g−1. This modification increased fines' hydrophilicity, as evidenced by enhanced moisture absorption capacity in dynamic vapor sorption analysis. These fines with additional functionality strengthened intermolecular bonding, leading to over 150% enhancement in tensile strength and Young's modulus when cast into thin films. Fines were substituted at 10–20 wt.% concentration to the fiber fraction of softwood thermomechanical pulp (TMP) and bleached chemi-thermomechanical pulp (BCTMP) forming handsheets. It was observed that fines modified with succinic anhydride and imidazole were more effective in enhancing paper strength, including tensile (up to 30%), burst (up to 39%) and tear (up to 4%) indices. This improvement was likely due to enhanced intermolecular bonding between modified fines and the fiber surfaces. By modifying mechanical pulp fines with succinic anhydride and imidazole, we have converted a potential heterogeneous waste product from the industry into a valuable by-product to enhance paper performance.

The primary heat transfer source in the conventional multi-cylinder drying of paper and board is conduction. Conduction is facilitated by high-tension contact with steam-heated cylinders, while convective drying, the main mass transfer source, operates as heated air flows over the article web in the pockets. This conduction process occurs at elevated temperatures and contact pressures to ensure effective contact between the wet paper web and the heated cylinders. The contact pressures and temperatures of the hot surface significantly influence the conductive drying characteristics. This research paper presents an experimental study that involves designing a simple lab-scale setup with in-situ and continuous sensing capabilities for various commercially available grades of paper and board. Embedded thermocouples measure the temperatures of the heated platen and the sheet, allowing the collection of flux data to determine heat transfer characteristics. The goal of this study is to ascertain the instantaneous contact coefficients for different basis weights as a function of moisture content. The acquired data will provide valuable insights and information toward process development, design, and simulation of the article drying process. [ABSTRACT FROM AUTHOR]

Thin coating layers of cross-linked polydimethylsiloxane (PDMS) and inorganic particles including glass spheres (GS), colloidal and fumed silica (aero and N20), montmorillonite (MMT), and kaolin (K) were attached onto Grade 1 Whatman filter paper (WFP) substrates using the spraycoating procedure to achieve superhydrophobic hybrid paper sheets. Coating formulations were varied in terms of their PDMS molecular masses and inorganic particles to prepare different samples. The effect of PDMS molecular weight and change in inorganic particle composition on the optical properties, surface roughness, barrier properties, surface chemistry, and topography was investigated. Hybrid paper sheets with ΔE00 values lower than 1 could be achieved, the surface roughness of which could be decreased by increasing the PDMS molecular weight in the coating formulation. Scanning electron microscopy studies revealed a homogeneous coating distribution, resulting in significant improvements in both the air and water barrier properties of the hybrid paper sheets. Spectroscopic investigations revealed the presence of interactions between the coating layer and the underlying paper substrate. Moreover, the distribution behavior of the inorganic particles on the spraycoated surfaces using the proposed method was also investigated using model compounds. [ABSTRACT FROM AUTHOR]

The potential of paper and paperboard as fiber-based materials capable of replacing conventional polymer-based materials has been widely investigated and evaluated. Due to paper's limited extensibility and inherent heterogeneity, local structural variations lead to unpredictable local mechanical behavior and instability during processing, such as mechanical forming. To gain a deeper understanding of the impact of mechanical behavior and heterogeneity on the paper forming process, the Finite Element Method (FEM) coupled with continuum modeling is being explored as a potential approach to enhance comprehension. To achieve this goal, utilizing experimentally derived material parameters alongside stochastic finite element methods allows for more precise modeling of material behavior, considering the local material properties. This work first introduces the approach of modeling heterogeneity or local material structure within continuum models, such as the Stochastic Finite Element Method (SFEM). A fundamental challenge lies in accurately measuring these local material properties. Experimental investigations are being conducted to numerically simulate mechanical behavior. An overview is provided of experimental methods for material characterization, as found in literature, with a specific focus on measuring local mechanical material structure. By doing so, it enables the characterization of the global material structure and mechanical behavior of paper and paperboard. [ABSTRACT FROM AUTHOR]

This research investigated the influence of the layered structure of paper on its selected strength properties. Two types of cellulose pulp were used: unbleached kraft pine pulp (UBSK) and unrefined bleached birch kraft pulp (BHK). Multi-ply papers were obtained from layers of appropriate grammage formed separately and bonded in a wet state. Paper layers were formed from primary pulps (UBSK and BHK) or their mixtures (threeply UBSK-BHK paper and three-ply UBSK-BHK-UBSK paper), from which various variants of laboratory paper samples were made. This work focused on three-layer papers. The obtained laboratory sheets were analysed for changes in tear resistance, tensile strength, bursting strength, short span compression strength (SCT), and corrugating medium test (CMT). In most cases, three-layer structures were characterised by higher strength parameters than single-layer papers. The tear strength and SCT of papers consisting of three layers formed from both mixed pulps were slightly lower than those of solid papers. The results demonstrate the feasibility of producing three-ply paper with significantly reduced variability in parameters such as elongation and bursting strength, which are inherently subject to high variability.

The primary aim of this research was to explore the feasibility of producing environmentally friendly composite materials by employing diverse hybrid matrices consisting of dammar natural resin, supplemented with small proportions of two synthetic resins: one epoxy and the other acrylic. A blend of paper and chicken feathers served as the reinforcing elements. The fabrication of these composite materials utilized a hand layup technique. Targeted for applications in the furniture industry or interior design, their mechanical properties were assessed through various tests. Specimens were obtained from the manufactured samples and subjected to evaluations for tensile strength, compression, flexure, vibrations, Shore hardness, and water absorption. Results indicated that irrespective of the testing method employed, the mechanical strength properties exhibited a decline with an increase in the percentage of dammar in the hybrid resins, whereas the elasticity properties demonstrated an increase with this percentage.

This article discusses the Arabic illuminated manuscripts produced in 14th- and 15th-century Egypt and Bilād al-Shām identified in this institution and aims to highlight their production context and material characteristics. The study of these manuscripts also gives an insight into the main phases and codicological features of the arts of the book during the Mamluk period. [ABSTRACT FROM AUTHOR]

Atmospheric pressure plasma polymerization represents a promising coating technology, addressing drawbacks of traditional processes (solvent use, multistep procedures, etc.) while enabling deposition of thin cross‐linked polymer layers with high contour fidelity. We address technological challenges with a novel plasma device that integrates multiple plasma source benefits and investigate the suitability of two plant‐based precursors, chia and tung oil, for plasma polymerization to hydrophobize glass and paper. Chia oil enables the deposition of thin, covalently bonded hydrophobic polymer layers. Such coatings have diverse applications especially inside the paper industry, where water repellents in the form of internal and surface sizing have always been an essential functionalization step. Using bio‐based precursors and reducing extra chemicals contributes to substituting fossil‐based or harmful substances. [ABSTRACT FROM AUTHOR]

This paper discusses three large, almost identical oval breverls from the eighteenth century burial contexts in present-day Republic of Croatia. Two of them were discovered during archaeological excavations in Žuberak and Prozorje, while the third one from Ližnjan had not been defined as breverl until now. Breverls are the rarest and most enigmatic devotional objects but the three analysed in this paper have a common link other than their appearance. They all contained religious medals from pilgrim sites and papers with the prayer against all evils and demonic attacks on one side and the blessings of saints, the prayer for the identification of those tortured by evil spirits, and the Prologue to John's Gospel on the other. This article compares the papers discovered in them, studies the motifs from the mentioned breverls and analyses other finds from them to provide answers to the questions of their place of production, the identity of the people who wore them and why. Tentative correlation of different bioarchaeological factors, such as age, sex, and health condition of the deceased can give us much information on who breverl bearers were. Apparently, they were the vulnerable members of society, such as pregnant women, people suffering from poor health, or, as prayers from the breverls suggest, individuals believed to be tortured by demons or evil spirits. Taking that into account, breverls were devotional objects believed to provide universal protection, a sort of medicine case for both physical and spiritual problems. [ABSTRACT FROM AUTHOR]

Paper manufacturers have long used silicone as the coating agent for release liners. However, silicone‐based release paper is very difficult to recycle due to covalent bonds between silicone and fibers. The most suitable solution to overcome this problem is to use alternative coating materials with adequate release properties, provided that they can be easily repulped in typical paper recycling facilities. We proposed a coating agent composed of phosphate esters and dimethylacetamide in order to manufacture a recyclable and efficient release paper. Analyses carried out on coated sheets showed that phosphate esters allowed the formation of a surface with adequate release properties (low peeling force and surface free energy). In addition, the residual adhesion values obtained with phosphate esters confirmed that they are well anchored on the backing paper surface, thus limiting the mass transfer to the adhesive tape.

In this research work, a coated paper was prepared with poly (butylene adipate-co-terephthalate) (PBAT) film to explore its use in eco-friendly food packaging. The paper was coated with PBAT film for packaging using hot pressing, a production method currently employed in the packaging industry. The coated papers were evaluated for their structural, mechanical, thermal, and barrier properties. The structural morphology and chemical analysis of the coated paper confirmed the consistent formation of PBAT bi-layered on paper surfaces. Surface coating with PBAT film increased the water resistance of the paper samples, as demonstrated by tests of barrier characteristics, including the water vapor transmission rate (WVTR), oxygen transmission rate (OTR), and water contact angle (WCA) of water drops. The transmission rate of the clean paper was 2010.40 cc m−2 per 24 h for OTR and 110.24 g m−2 per 24 h for WVTR. If the PBAT-film was coated, the value decreased to 91.79 g m−2 per 24 h and 992.86 cc m−2 per 24 h. The hydrophobic nature of PBAT, confirmed by WCA measurements, contributed to the enhanced water resistance of PBAT-coated paper. This result presents an improved PBAT-coated paper material, eliminating the need for adhesives and allowing for the fabrication of bi-layered packaging. [ABSTRACT FROM AUTHOR]

Cellulose nanocrystals (CNCs) and chitosan (Cht) have been studied extensively for oxygen and water vapour barrier coatings in biodegradable, compostable or recyclable paper packaging. However, rare studies have been performed by using scalable, inexpensive, and fast continuous slot-die coating processes, and none yet in combination with fast' and high-throughput near-infrared (NIR) light energy drying. In this frame, we studied the feasibility of a moderately concentrated (11 wt%) anionic CNC and (2 wt%) cationic Cht coating (both containing 20 wt% sorbitol related to the weight of CNC/Cht), by using plain and pigment pre-treated papers. The effect of coating parameters (injection speed, dry thickness settings) were investigated on coating quantity (dry weight, thickness) and homogeneity (coverage), papers' structure (thickness, grammage, density), whiteness, surface wettability, barrier (air, oxygen and water vapour) properties and adhesion (surface strength). The coating homogeneity was dependent primarily on the suspensions' viscosity, and secondarily on the applied coating parameters, whereby CNCs could be applied at 1–2 times higher injection speeds (up to 80 mL/min) and versatile coating weights, but required a relatively longer time to dry. The CNCs thus exhibited outstanding air (4.2–1.5 nm/Pa s) and oxygen (2.7–1.1 cm3 mm/m2 d kPa) barrier performance at 50% RH and 22–33 g/m2 deposition, whereas on top deposited Cht (3–4 g/m2) reduced its wetting time and improved the water vapour barrier (0.23–0.28 g mm/m2 d Pa). The balanced barrier properties were achieved due to the polar characteristic of CNCs, the hydrophobic nature of Cht and the quantity of the applied bilayer coating that can provide sustainable paper-based packaging.

This article presents a history and stylistic analysis of the avant-garde furnished apartment-studio of the Italian Futurist Giacomo Balla (1871-1958), commonly known as Casa Balla. The decor and the painterly interior design of the flat portray the utopian premise of 1920s Futurism, which aimed at a modern synthesis of the arts and their complete integration into reality, in an intimate way. The author of the essay describes the current state of the "Balla House", which, after many years of oblivion, has been restored and opened to the public in a new arrangement in 2021.

Accurately assessing the color quality of printed products becomes intricate when optical brightening agents (OBAs) are introduced in papers, as diverse interactions occur among different ink pigments and papers containing OBAs due to variations in ink formulation chemistries. Specifically, alkali‐based pigments, commonly used as spot colors, are carefully formulated to ensure consistency across production batches. The presence of OBAs, which absorb ultraviolet light and emit it in the visible spectrum, significantly affects color perception and accuracy on paper when interacting with these inks. This research marks an initial investigation into how OBAs in paper influence the color accuracy of five distinct alkali‐based spot color paste inks using a Little Joe ink proofer. The research examines the physical, optical, and colorimetric characteristics of two paper samples‐one with OBA and one without‐ and analyzes the colorimetric changes occurring during the ink drying process. The results indicate that reflex blue, purple, and violet spot colors achieved acceptable delta E (ΔE00) value of below 3 on non‐OBA paper, with rubine red being on the borderline at 3.1 after 48 h. In contrast, purple, rhodamine red and violet achieved acceptable ΔE00 below 3 on high OBA paper. The distinct behavior exhibited by certain inks led to the conclusion that achieving a consistent proofing procedure across diverse alkali‐based ink formulations is impractical.

Flexible and small-scale energy storage technologies are critical for future applications such as wearable electronics. In this context, paper has emerged as a lightweight, low-cost, and ecologically friendly flexible substrate for energy storage devices. This paper presents a simple method for fabricating a micro-supercapacitor (MSC) using a wax printing approach that can achieve high resolution without requiring complex processes. In addition, the developed MnO2–Au-paper (MAP) microelectrodes with high porosity exhibit enhanced charge and ion transfer while maintaining a stable flexibility. The solid-state micro-supercapacitor delivers a very large areal capacitance of 624.32 mF cm−2 at 0.2 mA cm−2 and is stable under external stress. The highest energy and power densities obtained for the present MSCs (55.5 μWh cm−2 and 1.59 mW cm−2, respectively), are much larger than those previously reported for pseudocapacitive MSCs, including flexible ones.

Phosphorylated fibers offer a broad range of applications, particularly in thermal insulation, notably with wood fibers, provided they exhibit improved mechanical characteristics. Despite encountering challenges in applying traditional papermaking methods, the creation of paper or board sheets with phosphorylated pulp fibers remains a challenge. Findings suggest that phosphorylation-modified fibers show increased roughness. Moreover, in comparison with unbeaten kraft sheets (KF) and thermomechanical pulp sheets (TMP), those made from phosphorylated kraft fibers (PKF), using a cationic coagulant and a flocculant, demonstrate significant enhancements in burst index, break index, and tensile energy absorption by 2.12 times, 1.7 times, and 2.77 times, respectively. Similarly, phosphorylated TMP sheets, prepared with a dual polymeric system (coagulant/flocculant), exhibit improvements of 1.42 times, 1.33 times, and 1.82 times, respectively, in these properties. The study emphasizes the ameliorating effect of cationic polymeric agents on the charge impact of phosphorylated fibers on overall sheet quality, while also highlighting the substantial influence of hot-pressing lignin-containing paper on all determined physical properties.

Enhancing paper hydrophobicity is of key importance for many paper-based applications. Fatty acids or vegetable oils and their derivatives replace environmentally harmful conventional coating materials but still require challenging chemical reactions for covalent attachment onto paper. Here, we show that simple storage of olive oil-coated cotton linter paper at 70 °C and subsequent Soxhlet extraction is able to endow paper with hydrophobic properties, reaching water contact angles above 130°. In-depth chemical and morphological analytics show the relevance of temperature and air accessibility during the aging process compared with aging at ambient temperature and under the exclusion of oxygen, underlining the importance of assessing a coating's long-term performance and stability under diverse storage conditions. Simple storage of vegetable oil-coated paper at elevated temperatures followed by extraction proves to be an easy way to produce stable covalently attached hydrophobic paper coatings with exceptionally low coating amounts.

At the beginning of the 20th century, the eclectic artist Mariano Fortuny y Madrazo patented two innovative methods for polychrome printing on fabrics and textiles, giving life to Fortuny fabric production in Venice. The first patent was related to colour application, while the second to a special machine that allows continuous printing using cylindrical rollers. Despite the descriptions, the methodology and materials used remain a secret. In collaboration with the Fortuny Museum in Venice, this research aimed at studying and identifying the different steps of Fortuny printing methodologies. Printing matrices, fabrics and raw materials found in the artist's studio were analysed in a multi-analytical campaign through digital microscopy, X-ray fluorescence (XRF), Fourier-transform infrared spectroscopy in attenuated total reflectance (FTIR-ATR), μ-Raman spectroscopy and gas chromatography–mass spectrometry (GC–MS). Three main pigments were identified in paper samples: ivory black, a copper-based pigment, and a carbon black pigment with ultramarine for blues. The pigments were bound with linseed oil and colophony in varying proportions. Polychrome silk fabrics were dyed with a base colour, and then the coloured patterns were superimposed by continuous printing. Prussian blue was identified as one of the textile inks. Results provided a better understanding of printing methodology. [ABSTRACT FROM AUTHOR]

The paper and pulp industry stands out to be one of the industries that are growing at a fast pace. Besides their characteristics such as high water consumption of 695.7 million m3 per year and subsequent high energy consumption, there are plenty of environmental impacts arising from this industry. Approximately 300 different types of harmful organic pollutants such as phenols, dioxins, and other organic substances are the significant effluents of the paper and pulp industry. As per the regulations set by the world health organization (WHO), the permissible limit of such pollutants is less than 1 ppm. Since the complete degradation of these pollutants is difficult to achieve using conventional techniques, advanced oxidation processes (AOPs) are widely being used as promising alternatives. On the other hand, depleting non-renewable energy resources are forcing industries to look for energy-efficient technologies. Photocatalysis is one such AOPs, which has the potential to solve the energy-wastewater nexus and is the primary focus of this review in terms of waste treatment from the paper and pulp industry. The photocatalytic materials induce photoreactions by receiving photon energy from light. However, harnessing light energy to the fullest is a challenge owing to the limited share of UV spectrum in sunlight. Different composite photocatalysts at different loadings, pollutant concentrations, and contact time along with their respective efficiencies are reported. The enhancement in thermodynamic driving force due to shift in Fermi energy levels with a suitable example is explained. The dependence of photocatalysis on various factors such as organic species, temperature, and light intensity makes it tough to predict the precise kinetic model in real-life experiments. The hydrogen production from the degradation of organic pollutants was discussed vividly and by optimization of the processes, an estimated amount of 0.45% of the total world's energy could be produced from the paper and pulp industry alone.

Cellulosic-based materials such as hemp fabric and paper have combined characteristics of renewability, biodegradability, flexibility, and recyclability. However, regular products are not suitable for use in unconventional applications due to inherent limitations, and accordingly, enabling new capabilities is a necessity. To this end, the conversion of regular hemp fabric and paper into high-strength products with hydrophobic function via surface engineering was explored. The fluorinated waterborne polyurethane (FWPU) emulsions were first synthesized as functional coatings by in-situ polymerization. The structure and properties of the FWPU emulsion and film were characterized by FTIR, XRD, SEM, TG, and XPS. The results showed that the grafting of perfluorooctanol imparts WPU film excellent hydrophobicity, and the water contact angle increases from 71.2° to 105.9°. After the FWPU coating, the water contact angles of the hemp fabric and paper increase from 0° to 117.1° and 112.8°, respectively. Quite encouragingly, the coating generation of waterborne polyurethane-derived functional additives led to the increase of mechanical strength by more than 23% and 82%, in the case of qualitative filter paper and hemp fabric. Meanwhile, the folding strength of filter paper is increased by 132 times. Overall, this functionalized waterborne polyurethane coating would direct paper and hemp fabric toward diversified applications. [ABSTRACT FROM AUTHOR]

This article asks whether the slow process of divesting Indian native schoolteachers of their traditional authority was only about new concepts and representations of education and knowledge. Following the methodological idea of constellations of affordances, emphasising a relational ontology, the article discusses whether changes in the shape and the relations of objects in Indian classrooms together with the arrival of new objects may have played a silent role in the process of erosion of schoolteachers' authority. Based on a wide range of official and missionary sources, but also referring to individual native voices, the article reconstructs more pervasive and subtle transformations of native elementary classrooms, focusing on surfaces for writing and on "books". The article argues that shifts in the materialities of elementary native schooling took place that repositioned old "gurus" in an unfavourable light before the take-off of teacher training institutions would provide for new definitions of their role as schoolmasters.

The forest products industries play a vital role in the economic, social, and environmental well-being of the Lake States in the United States. While various economic contribution analyses of forest products industries have been conducted to highlight the importance of such industries to regional economies, little effort has yet been made to parse out the contribution of activities in the value chain. The value chain is a series of steps involved in producing goods or services. This study used a matrix decomposition approach to estimate the economic contribution along the value chain through multiple pathways of four forest resource-based industries using wood as inputs: biomass power generation, sawmills, paper mills, and the construction of new single-family residential structures in the Lake States. The direct and indirect economic output values in 2017 resulting from the construction of new single-family residential structures were $19.1 billion, sawmills were $2.5 billion, paper mills were $17.6 billion, and the biomass power generation industry was $759 million. Of the direct and indirect economic output contributed by each industry, the highest percentage of output attributable to the logging industry was observed from the sawmills industry (12%), followed by biomass power generation (9%), paper mills (1.4%), and the construction of new single-family residential structures (<1%), respectively. The percentage of total economic output attributable to the stumpage industry in the region followed a similar trend as commercial logging for all value-chain industries. The relative economic contribution of the value-chain industries to the total economic contribution of the final industry varied based on whether the industry was a primary or secondary forest products industry and the pathways used for sourcing wood inputs.

This study explores the efficacy of 1-hexyl-3-methylimidazolium bis(trifluoromethylsulfonyl)imide and 1-hexyl-3-methylimidazolium chloride as cleaning agents for aged cellulosic artifacts. A 10% v/v acetone solution of these ionic liquids (ILs) effectively removes the brownish-yellow color of aged paper in a 10 min immersion treatment. Colorimetric analysis shows a remarkable increase in lightness (L*) by up to 40% and a decrease in red/brownish tones (b*) after IL treatment. The cleaning process also deacidifies the paper, shifting the pH to neutral-slightly basic levels and enhancing its long-term stability. Optimal pH outcomes are achieved, with ionic liquid consumption values of 0.4–0.6 g/g of paper. The FTIR analysis revealed structural changes in cellulose induced by the washing step, which is mainly due to the reorganization effect imparted by the ionic liquids. Furthermore, ILs mobilized degraded compounds and acidic species, aiding in their extraction during the restoration process. Mechanical testing indicated an enhancement in the overall tensile strength and strain at break values for IL-treated papers by up to 33%. This study demonstrates the multiple benefits of alkylimidazolium ionic liquids for preserving and restoring cultural heritage artifacts made of cellulosic materials. [ABSTRACT FROM AUTHOR]

The terahertz spectrum of paper has been measured from room temperature to cryogenic temperatures. As the paper is cooled, the main absorption lines move to higher frequencies. The same behaviour is observed for two types of paper. The spectrum at base temperature provides the most direct comparison yet with calculations made using density functional theory, which assume the studied material to be at absolute zero temperature. These unique experiments should spur the development of better theoretical models of cellulose and cognate materials. [ABSTRACT FROM AUTHOR]

The global overabundance of electronic waste and ever‐increasing concerns regarding the energy‐and material‐intensive manufacturing processes associated with traditional electronics are driving the development of solution‐processed, degradable electronics. Of note, the industry‐dominating prevalence of harmful lead‐based materials in sensing and actuating devices drives the push for more eco‐friendly solution‐processed piezoelectric systems. Yet current ecofriendly multi‐material printing processes are limited by both the conventional challenges of multilayer processes as well as the low‐temperature thermal constraints of biodegradable materials. Herein, a novel approach for fabricating fully printed, sustainable piezoelectric transducers on paper substrates is presented. Low‐temperature screen‐printing processes are used to integrate non‐toxic KNbO3 layers with degradable carbon‐ or zinc‐based conductive inks into devices. The influence of electrode material on device characteristics is assessed, with effective piezoelectric coefficients reported as high as 4.6 pC N−1 and 5.1 pC N−1 for devices with carbon and zinc electrodes respectively. The potential of the developed technology is then demonstrated through the first‐ever instance of fully printed piezoelectric force sensors and acoustic speakers comprised entirely of green materials. By demonstrating entirely printable green piezoelectric devices compatible with various electrode materials, this work serves as a step towards developing more complex sustainable piezoelectric technologies in the future.

The main objective of the paper was to establish the effectiveness of paper waste added to a growth medium, avoiding waste management processes, which require time and energy, but providing an efficient solution for using paper waste as a nutrient substrate for plants cultivated in containers. It was specifically aimed to evaluate the percentage of peat that could be replaced by waste paper for the ornamental plant Ficus benjamina cv. 'Golden King' in an experiment with 4 variants in 3 repetitions (V1 - 100% peat, V2 - 80% peat+20 % paper waste, V3 - 70% peat+30% paper waste, V4 -50% peat+50% paper waste) in 2023. In conclusion, based on the research carried out, it can be stated that paper waste mixed with peat in a proportion of 30% can be used as an alternative substrate. [ABSTRACT FROM AUTHOR]

This article explores the assortment and primary methods of waste collection within the Reichskommissariat Ukraine during the occupation by Nazi forces. The Ukrainian occupational press serves as the primary source for this article. It demonstrates that the extraction of various resources and the plundering of material valuables were directed towards supporting the economic and military power of the Third Reich, with waste collection policies being one of its facets. To facilitate this activity in this realm, the Nazis utilized existing infrastructure within the territory of Ukraine, including warehouses, factories, and offices of Soyuzutyl, established on the eve of the Second World War, as well as the infrastructure of the consumer cooperative system. It is shown that the specificity of Ukraine lies in assigning waste collection duties to consumer cooperatives, which transformed into the primary suppliers of various raw materials for the needs of the Third Reich. Local administrations and individual cooperatives actively participated in this endeavor, and special associations were also established. Additionally, the occupying authorities sought to involve schoolchildren and the broader population, developing various incentive systems for this purpose, although the participation of these actors was minimal. The article examines the peculiarities of waste collection propaganda within the territory of the Reichskommissariat Ukraine, which was based on ideological motives such as gratitude for liberation from Soviet rule, as well as economic motives related to the need for waste to produce consumer goods for the local population by enterprises of the Nazi regime. It is argued that primary attention was given to collecting scrap black and colored metals, as well as bones, paper, and rags. The author suggests that the scale of economic plundering of Ukraine was much larger than commonly believed, yet acknowledges that this requires further in-depth research involving a wide range of archival sources.

In recent years, due to environmental awareness regarding the harmfulness of polymeric materials, there has been a growing interest in using papers, especially those from alternative raw materials. The importance of using all available raw materials is imperative today. Raw materials that were once viewed as waste are now of great importance because they have the ability to replace raw materials that are used irrationally or are lacking. Cereal straw is a lignocellulosic material that could be used in the paper industry and in the production of increasingly prevalent paper packaging. The aim of this research was to analyze the relationships between the qualitative parameters of straw-based printed papers containing 30% agricultural residues (wheat, barley, or triticale). The influence of two qualitative parameters (ink penetration depth and optical ink density) on the print-through was observed using multiple regression analysis on straw-based papers produced at the laboratory level. Throughout the research, 100% recycled wood paper was used as a reference sample. The results of the regression analysis showed that none of the variables individually make a statistically significant contribution to the prediction of the dependent variable in a linear context, that is, they indicate a non-linear interaction between the variables and the specific conditions under which the dependent variable reaches local extremes and changes in the gradient. Considering the results of the regression analysis and the visualization of the relationship, the model was additionally tested with other independent variables (paper type). From the results obtained, it can be concluded that the alternative straw-based paper with 30% barley pulp has the best interaction between ink and paper, which is the most similar to the reference sample in terms of printability, while the alternative straw-based paper with 30% wheat generally differs significantly from the reference paper when all three prints are considered.

Identifying the factors that influence the citation of articles helps authors improve the impact and reach of their research. Analysis of publications in the Journal of Fish Biology between 2008 and 2021 revealed that variables such as the number of keywords, abstract length, number of authors, and page length were associated with higher impact papers. These trends applied to both review and regular papers. These findings suggest that papers that are more informative, have higher numbers of authors, and have more keywords are more likely to be cited. Adoption of some simple "best‐practice" behaviors can improve the likelihood that a paper is cited. [ABSTRACT FROM AUTHOR]

Hemp hurd fiber, a low-value waste stream from the hemp industry, has potential downstream applications as an alternative to non-renewable plastics for single-use food service ware and packaging applications. Packaging paper substrates made from chemically pulped hemp hurd, mixed in varying ratios with bleached thermomechanical radiata pine pulp were developed and tested. Handsheets were characterized using several mechanical property tests including tensile strength, tearing resistance, burst strength, short-span compression, ring crush, together with Gurley air resistance, contact angle, and Cobb60 tests. Generally, addition of hemp hurd fibers significantly improved handsheet mechanical properties. Hot-pressing of the handsheets so as to approximate molded fiber thermoforming further enhanced their performance, with pure hemp hurd handsheets having the highest mechanical properties and barrier performance. A prototype was successfully thermoformed from hemp fiber, demonstrating overall feasibility of this fibre source for molded fibre objects. [ABSTRACT FROM AUTHOR]

Flow and spontaneous imbibition phenomena in porous media are important for various industrial applications, including printing and medical lateral flow assays. Their quantitative characterization is important to better understand and select the appropriate raw materials. However, standard methods often require time-consuming tests, and/or expensive equipment. Different time scales must be considered, limiting the range of possible characterization tools. A novel experimental approach based on image analysis for characterizing spontaneous imbibition processes is presented. Hence, ultra-fast diffusion may be quantitatively characterized. Models are issued from the literature to consider physical phenomena at small (milliseconds) and medium range (seconds) of time scales. The obtained experimental data fit with theoretical results, providing valuable insights into the understanding of fluid flow behavior at different time scales. Furthermore, the identification of some physical properties for either the fluid, or the substrate, based on the theoretical models are possible, as the contact angle, which remains to be otherwise challenging. This study contributes to bridging the gap between spontaneous imbibition and capillary phenomena at different time scales, their modeling, and a characterization of material and/or fluid properties paving the way for enhanced understanding and control of fluid behavior in porous media. Different papers are considered to illustrate the method. [ABSTRACT FROM AUTHOR]

This work presents the results of a transdisciplinary analysis performed on Harward's Almanac (Dublin, 1666), an extremely rare volume currently housed in the National Library of Ireland. The uniqueness and historical value of the Almanac is related to the presence of nineteen handwritten poems, entered by an anonymous scribe. These record textually important English clandestine satire circulating anonymously in Dublin in the late seventeenth and early eighteenth century. Following a comprehensive historical assessment, it appeared evident that the current order of leaves was incorrect. To reconstruct the correct order of the leaves, and hence the likely sequence in which the manuscript poems were inscribed, this study employed a codicological/paleographic analysis complemented by analytical (X-ray fluorescence, XRF) and statistical (Self Organizing Map, SOM) investigation. Specifically, point XRF analysis was carried out for each handwritten page of the Almanac, allowing identification of ink elemental compositions (iron-based ink) and successfully supporting the validity of historical hypotheses on the poems' order of inscription. The statistical organization of XRF data by SOMs allowed easy bi-dimensional visualization of the data set (54 points) and identification of ink similarities, once more validating the historical assessment.

Due to the surface hydrophobicity, the absorbing effect of the tobacco extract droplets on the reconstituted tobacco paper is unsatisfactory. Therefore, the surface property regulation of the tobacco paper has gained increasing attention. This work reports a novel argon (Ar) plasma treatment technique for improving the surface hydrophilicity and bacteriostatic effect of the paper. Firstly, Ar plasma was selected as the treatment gas and its improving effect was demonstrated through studying the contact angle changes of water droplet on the A4 paper. Then, the capillary fibers on the paper were bombarded by Ar plasma jet. The extract droplet contact angle on the reconstituted tobacco paper-15 s surface is only 14.6° within 1 s. In comparison to the pristine paper (5.9°/s), the absorption dynamic of the droplet increased to as high as 62.5°/s, which indicated the hydrophilicity was greatly improved by the Ar plasma method. The mechanism for improving the surface hydrophilicity of the cellulose in the tobacco paper also contributed to the generation of holes by Ar plasma jet, which increased the surface permeability of cellulose. At last, Ar plasma treatment showed excellent bacteriostatic effect, which could effectively inhibit the propagation and growth of fungi, Escherichia coli, and Staphylococcus aureus on the tobacco paper.
