Abstract Lithium-ion batteries, with their advantages of high energy density, no memory effect, and long cycle life, are widely used in new energy vehicles and emerging energy storage applications. Among these processes, electrode coating is one of the crucial manufacturing techniques for lithium-ion battery electrodes, with slot-die coating being widely adopted in practical engineering applications due to its advantages of high coating speed, wide coating width, and high precision, though the uniformity of coating slurry is affected by multiple factors and remains a focal point of research for both engineers and academic researchers.

Abstract The application of different coatings on solar photovoltaic (PV) panels can be an efficient solution to increase performance and further mitigate the emission of greenhouse gases. This study uses the Life Cycle Assessment (LCA) methodology and the environmental payback concept to analyze the effects of the application of a nano-silica coating on a solar PV system installed in the Brazilian Northeast. Firstly, an uncoated reference 16.4 MW PV system is designed, and the detailed inventory is presented (PV panels, supporting structure, inverters, junction boxes, cables, transportation, maintenance and operation—including the replacement of equipment). The results… More > Graphic Abstract

Abstract The main objective of the study was to prepare a highly active antimicrobial remedy by combining active agents such as tannic acid and silver nanoparticles, which are usually used separately. This was achieved by applying a coating of 11 alternating layers of an insoluble complex of tannic acid with polyvinyl alcohol on paper by the layer-by-layer approach, on the surface of which uniformly distributed spherical silver nanoparticles of uniform size, mainly 20–30 nm, were synthesized by in situ reduction using tannic acid, which also acts as a stabilizer, or an external reducing agent, which prevented polyphenol More > Graphic Abstract

Abstract Food packaging is becoming popular as the consumption of ready-to-eat food products rises. Easy-to-use, non-biodegradable plastic packaging is commonly used in food packaging, contributing to the deteriorating environmental situation. This issue increases the concern for the environment and encourages the usage of alternative materials. Cellulose nanofibrils (CNF) are abundant and biodegradable, which makes them ideal candidates to replace plastic coatings. The ability to form H-bonds between the hydroxyl groups makes coated paper with CNF have good strength, but poor barrier properties. The barrier properties can be improved by grafting DMAEMA or HEMA onto CNF (CNF-g-PDMAEMA… More > Graphic Abstract

Abstract The thermal stability of lithium-ion battery separators is a critical determinant of battery safety and performance, especially in the context of rapidly expanding applications in electric vehicles and energy storage systems. While traditional polyolefin separators (PP/PE) dominate the market due to their cost-effectiveness and mechanical robustness, their inherent poor thermal stability poses significant safety risks under high-temperature conditions. This review provides a comprehensive analysis of recent advancements in enhancing separator thermal stability through coating materials (metal, ceramic, inorganic) and novel high-temperature-resistant polymers (e.g., PVDF copolymers, PI, PAN). Notably, we critically evaluate the trade-offs between thermal… More >

Abstract Proton exchange membrane fuel cells (PEMFCs) have gained increasing interests as promising power sources due to their ability to convert hydrogen and oxygen directly into electricity with high efficiency and zero greenhouse gas emissions. Bipolar plates (BPs) are considered as a critical component of PEMFCs, serving to collect current, separate gases, distribute the flow field, and conduct heat. This paper reviews the technical status and advancements in BP materials, with special focus on strategies for enhancing interfacial contact resistance (ICR) and corrosion resistance through conductive polymer (CP) coatings. First, commonly used BP materials in PEMFCs More >

Abstract Konjac is an ideal candidate for edible coatings on fruits due to its hydrophilic properties, film-forming ability, barrier properties, safety, and biodegradability. Meanwhile, the high market demand for strawberries necessitates post-harvest treatment to extend their shelf life and preserve their quality, as strawberries are known for their fragile skin and soft texture. To fully utilize konjac and develop high-quality coating films, native konjac flour (NKF) and konjac glucomannan (KGM) were extracted from its corm and used as a coating film for strawberries in the present study. Therefore, this study aimed to compare the physical properties… More > Graphic Abstract

Abstract A Ni/C-MoS₂ coating was electrospark deposited by using an electrode made of sinered Ni-C-MoS₂ composite on a CrNi3MoVA steel substrate, and its nano-mechanical properties and tribological properties were obtained by utilizing nano-indenter and friction-abrasion testing machine. The results showed that the phase constitution of the as-deposited Ni/C-MoS₂ coating mainly includes graphite, MoS₂, γ-Ni, MoO₂, NixS and MoC. Compared with the CrNi3MoVA steel and Ni/MoS2 coating, the Ni/C-MoS₂ coating exhibits better tribological properties due to the matrix strengthened by MoO₂ and MoC, and the synergistic lubrication effect of graphite and MoS₂ in the Ni/C-MoS₂ coating.

Abstract Catheters are among the most frequently used medical tools in modern therapies. Several diseases are treated by catheters (e.g. hydrocephalus) in cardiovascular, urological, gastrointestinal neurovascular, and ophthalmic diseases. Approximately 150 million intravascular catheters are implanted annually in the United States alone. However, although very efficient, following their insertion, catheters are subjected to numerous complications, including resistance to flow, blockage, and mechanical malfunctions, and being subjected to host-immune response and microbial infection. To overcome these complications, we proposed to develop the next generation of catheters with improved functionality and liquid flowability. We assume that polymeric coating More >
