Abstract A Shape Memory Polymer Composite (SMPC) is developed by reinforcing an epoxy-based polymer with randomly oriented short glass fibers. Diverging from previous research, which primarily focused on the hot programming of short glass fiber-based SMPCs, this work explores the potential for programming below the glass transition temperature (Tg) for epoxy-based SMPCs. To mitigate the inherent brittleness of the SMPC during deformation, a linear polymer is incorporated, and a temperature between room temperature and Tg is chosen as the deformation temperature to study the shape memory properties. The findings demonstrate an enhancement in shape fixity and More >

Abstract PU, or polyurethane, features a repeating urethane group (-NH-COO-) in its molecular structure. Traditionally, PUs are synthesized from isocyanate and polyol compounds derived from fossil resources through polymerization reactions. The depletion of fossil fuels and the increasing climate problems call for the expansion of more renewable sources of chemicals, such as modern biomass. However, the conversion of biomass into chemicals is challenging due to the inherent molecular complexity of its composition. In recent years, advances in green chemistry have led researchers to focus on developing bio-based polyurethanes by sourcing polyols, isocyanates, and chain extender precursors More >

Abstract The food industry prioritizes food safety throughout the entire production process. This involves closely monitoring and evaluating all potential sources of biological or chemical contamination, starting from entering raw materials into the production chain and continuing to the final product. Biofilms on food surfaces or containers can harbor dangerous pathogens, such as Listeria monocytogenes. Therefore, it is essential to continuously manage microbial contamination on food contact surfaces to prevent foodborne infections. Recently, there has been increasing interest in using nanomaterials as surface coatings with antimicrobial properties in the food industry, especially since traditional disinfectants or antibiotics… More >

Abstract The global scarcity of clean water is an escalating issue due to climate change, population growth, and pollution. Traditional water purification technologies, while effective, often require significant energy input and complex infrastructure, limiting their accessibility. This review explores the use of conjugated polymer hydrogels as a promising solution for solar water purification. Conjugated polymer hydrogels offer unique advantages, including high photothermal conversion efficiency, effective heat management, and rapid water transport, which are crucial for efficient solar-driven water evaporation. By leveraging the properties of these hydrogels, it is possible to significantly reduce the energy required for More >
