Summary: The current study focuses on developing an active hybrid bio-nanocomposite material by embedding TiO2 and silver nanoparticles into the biopolymer alginate. The Alginate/TiO2 bio-nanocomposite beads were obtained by mixing a fixed amount of TiO2 nanodispersion with alginate solution and crosslinking with CaCl2 solution. The Alginate/TiO2 beads in the wet state were then loaded with silver ions and reduced to silver nanoparticles through irradiation technique. The morphology and catalytic ability of the prepared bio-nanocomposite beads were studied, and it was found that the embedding of Ag nanoparticles greatly improved the catalytic hydrogenation performance in the reduction of 2-NP to 2-AP.

Summary: In this study, AA6082 aluminium alloy matrix composites with various weight fractions of titanium diboride were successfully prepared using an in situ casting technique. The SEM and XRD analyses confirmed the dispersion of TiB2 particles in the matrix alloy and the presence of TiB2 phases. The mechanical and tribological properties of the AAMCs were significantly improved with the addition of TiB2 particles, leading to a decrease in wear rate and an increase in flexural and compression strength compared to the base AA6082 alloy.

Summary: Phytoremediation of metals from water and nutrient media exposed to waste metal cutting fluid was tested using Azolla imbricata. Results showed that biomass was higher in nutrient media than in water media without waste metal cutting fluid. However, growth failed when exposed to high concentrations of waste metal cutting fluid. Correlation analysis revealed that biomass was positively affected by temperature and negatively affected by humidity and metal accumulation. The average accumulations of Al, Cd, Cr, Fe, Pb, and Zn were observed and the bioconcentration factor indicated Azolla imbricata acts as a hyperaccumulator of Zn and as an accumulator or excluder of other metals. Overall, the phytoremediation performance of Azolla imbricata in multi-metal-contaminated waste metal cutting fluid was high in water media under all environmental conditions. The use of water media was determined to be an economically feasible approach for the removal of metals from waste metal cutting fluid.
