Summary: The characteristics of improved poly (vinyl chloride) (PVC)/ZnO nanocomposites are evaluated by dispersing 0, 2, 4, and 6 phr of ZnO nanoparticles in the polymer matrix and compressing them into circular disks. The dispersion properties, as well as the electrical, optical, thermal, and dielectric properties of the PVC, are studied. The hydrophobicity of the nanocomposites decreases with the increase in filler content, and the thermal properties show enhancement. In addition, the optical band gap energy decreases and the melting temperature increases with the addition of ZnO nanoparticles. The structural stability of the materials under hydrothermal stresses is also analyzed.

Summary: This study investigated the effects of refining methods (roller ball milling, vertical stirring milling, and high-pressure micro jet homogenization) on the suspension, microstructure, and electrical properties of ZnO varistors through comparison. For the first time, a high-pressure micro jet homogenizer was employed to improve the homogeneity of the varistor ceramics' microstructure. When the homogenization process was carried out for 5 minutes after vertical stirring milling, the particle size distribution range of the suspension became narrower, resulting in more uniform grain size of the sintered ZnO varistors and excellent electrical comprehensive performance.

Summary: Hygroscopic biopolymers like proteins and polysaccharides have unstable mechanical properties due to humidity variations. Thicker samples of wheat gluten, a highly hygroscopic biopolymer, exhibit greater mechanical stability than thinner samples, which is attributed to slow water diffusion caused by the rigid polymer structure. Moisture uptake in glycerol-plasticized wheat gluten is significantly slower in thicker plates, taking more than a year to reach saturation compared to one day in thinner plates. The moisture-induced changes in mechanical properties are also affected by swelling-induced mechanical effects.

Summary: The functionalization of keratin from poultry feathers was evaluated using one- versus two-stage processes with two functionalization agents (succinic anhydride-SA and ethylene dianhydride-EDTAD). The functionalization improved liquid swelling capacities of keratin, with up to 400% water, 300% saline, and 85% blood uptake compared to non-functionalized keratin. One-stage functionalization with EDTAD showed better performance and resource-saving advantages over two-stage processes, making it a potential liquid absorbent material.

Summary: Polyethylene based ionomers have been synthesized with thermo-mechanical and dielectric properties comparable to cross-linked polyethylene (XLPE), making them a promising alternative for high voltage insulation in future HVDC power cables. The ionomers feature similar crystallinity, melting temperature, rubber plateau modulus, and thermal conductivity as XLPE, while remaining melt-processable. Their production process is free of byproducts, resulting in a highly insulating material with low dielectric loss and DC electrical conductivity.

Summary: The development of wood-based thermoplastic polymers that can replace synthetic plastics is environmentally important. This study used molecular dynamics simulations and experiments to investigate the influence of ring opening on the properties of dialcohol cellulose and how temperature and water affect these properties. The simulations showed that ring opening had a higher impact on providing molecular mobility at high temperatures, which was also observed in experiments. This opening had the strongest effect on processability above the glass transition temperature and in wet conditions, and it also lowered the glass transition temperature. The results demonstrate the valuable use of molecular dynamics in developing wood-based materials with optimal thermoplastic properties.

Summary: Ultrasonication was used to incorporate glycerol or urea into paper films, increasing their ductility to 35%. This study aimed to enhance the ductility of cellulose-rich materials by adding low molecular weight plasticizers such as glycerol, urea, citric acid, and tannic acid. Ultrasonication was employed to mechanically disintegrate the fibers and aid in plasticizer absorption. Glycerol or urea combined with ultrasonication resulted in both internal and external fibrillation of the fibers, significantly increasing ductility, while citric or tannic acid reduced ductility due to the formation of covalent cross-links in the fibers.

Summary: Global warming and environmental concerns drive the search for alternative fuels in international shipping. A life-cycle analysis (LCA) is used to assess the environmental impact of different fuels to find the most sustainable alternative. However, most LCA studies do not consider marginal emissions, which are important when predicting large-scale fuel transitions. This study aims to assess the marginal emissions of several currently available marine fuels to identify the most promising option. The results show that, despite lower average emissions, biofuels exhibit equally or higher marginal greenhouse gas emissions due to limited availability of climate-efficient biofuels. Additional measures are needed to significantly reduce the climate footprint of shipping.
