Summary: This study aimed to modify soy protein isolate (SPI) using dielectric barrier discharge (DBD) plasma and investigate the effects on its structural and physicochemical properties. Results showed that plasma treatment enhanced the emulsifying properties, solubility, water holding capacity, and foaming activity of SPI, with the best results obtained at 18 kV for 15 minutes. Exposure to DBD plasma at 18 kV led to an increase in free and reactive sulfhydryl and free carbonyl contents. FTIR and CD results indicated partial denaturation and unfolding of alpha-helix structure of SPI followed by the formation of protein aggregates.

Summary: The exceptional mechanical properties of aramid fibers make them a popular choice for high-performance materials, but their potential is limited due to their surface properties and interfacial bonding strength. Supercritical carbon dioxide (scCO(2) )-assisted techniques show great potential in enhancing the surface modification of aramid fibers with functional groups and nanoparticles. This article reviews the advancements and challenges in using scCO(2)-assisted techniques for aramid fiber modification and explores the future prospects of this technology.

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.
