Summary: This study investigates the antibacterial activity of cotton containing silver nanocapsules prepared by atmospheric pressure plasma (APP) deposition. The nanocapsules consist of a shell and a silver nanoparticle (AgNP) core, which is responsible for the antibacterial activity while the shell suppresses the potential toxicity of AgNPs. The surface morphology and elements of the samples were analyzed using scanning electron microscopy (SEM), energy dispersive x-ray (EDX), and x-ray photoelectron spectroscopy (XPS). The results show that the skin of the cotton fibers gradually falls off after 3 minutes of APP treatment, and the Ag content rises to 1.6% after 10 minutes of APP deposition. In addition, antimicrobial activity tests demonstrate that the reduction rates of Escherichia coli and Staphylococcus aureus can reach 100% after 10 minutes of treatment, indicating excellent antibacterial activity. Furthermore, the UV absorption properties of the cotton are also improved, providing broader application prospects for antibacterial cotton.

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.
