Summary: This study developed a cost-effective method to increase the surface hydrophobicity of silicone rubber through electron beam irradiation in the presence of glycerol. It was found that the network structure formed on the silicone rubber surface was responsible for the increased hydrophobicity. This method has the advantages of cost-effectiveness, easy operation, and non-toxicity of glycerol, making it applicable for large-scale industrial production and modification of silicone rubber.

Summary: The study investigated using waste wool fibers as alternative reinforcing agents for silicone elastomers, finding significant improvement in physical properties when chemically modified wool fibers were incorporated. The efficiency of reinforcement depended on the loading of wool in the silicone elastomer and fiber length. Surprisingly, naked short wool fibers showed excellent reinforcement in silicone elastomers, surpassing the performance of fumed silica at the same loading.

Summary: In order to enhance the mechanical and anticorrosion ability of carbon nanotubes (CNT), CNT were dispersed into homemade silicone-polyurethane (SPU) resin, but before mixing with SPU, CNT were modified using four different approaches. The modified CNT with SiO2-TiO2 nanoparticles exhibited the best mechanical properties and chemical resistance, with a significantly lower corrosion current density compared to unmodified CNT. This may be attributed to the increased roughness of the CNT surface caused by the covered SiO2-TiO2 nanoparticles, which improves their dispersion in SPU resin.

Summary: Polyurethane (PU) sponge is widely used but not bio-degradable, causing environmental pollution. Existing PU recycling techniques face problems, which are being addressed globally. We propose a scalable and eco-friendly technique for converting scrap PU sponge into superabsorbent for wastewater treatment. The conversion involves modifying the surface energy and roughness of the PU sponge using electron beam radiation. The recycled PU shows superhydrophobicity and effectively removes toxic solvents, oily liquids, and dyes from water media.

Summary: Refractory metal based alloys have great potential as structural materials for high-temperature applications due to their high melting points. However, they are prone to catastrophic oxidation at around 700 degrees C. This study investigated the effect of aluminium diffusion coatings on the oxidation resistance of pure molybdenum, niobium, tantalum, and tungsten. The results showed that the aluminization improved the oxidation behavior and decreased the oxide growth rate for molybdenum and tantalum.
