Summary: In this study, CuO nanoparticles were synthesized via hydrothermal synthesis and then modified with different polymers to optimize bacteriostatic effects. Among them, PDA-modified CuO NPs showed excellent antibacterial activity with a bacteriostatic rate of 85.8%. Their superior performance can be attributed to their smaller size, surface charge, and favorable van der Waals interactions at pH 7.4, which increased their affinity for the lipopolysaccharide-containing outer membrane of E. coli.

Summary: The study found that both copper and copper oxide particles on ceramic surfaces exhibited similar antibacterial activity, which was mainly dependent on phase crystallization. The slightly higher amount of tenorite phase in copper-modified surfaces compared to copper oxide resulted in a slightly more pronounced bactericidal effect.

Summary: A simple and cost-effective approach was used to synthesize biocompatible nanocomposites of graphene oxide, glucose, and copper oxide. The synthesized nanocomposites were characterized for their physical properties and studied for their antibacterial properties. The results showed that the nanocomposites synthesized at 35 degrees C exhibited better antibacterial activity compared to other nanocomposites and graphene oxide. The Cu/Glu/GO nanocomposites demonstrated significant antibacterial properties due to the synergistic effect of copper, glucose, and graphene oxide.

Summary: This study investigates the effects of 2 MeV Ni+ ion beam irradiation on the surface, structural, and mechanical characteristics of titanium. Various characterization tools were used to analyze the modifications in the ion beam irradiated targets. The results show that the increase in ion fluence leads to surface and structural changes, such as expansion, sputtering, and localized melting. The mechanical testing results indicate an increase in hardness, yield stress, and ultimate tensile strength with the increase in ion fluence.

Summary: The reversible controlled exchange bias effect in Co/NiO heterostructures is achieved at room temperature using all-solid-state Li-ion redox capacitors. The nonvolatile and reversible control of exchange bias is obtained through the intercalation and deintercalation of Li-ion in antiferromagnetic NiO via galvanostatic charge and discharge process. The ion migration-controlled exchange bias mechanism in Co/NiO heterostructures is studied using various structural, electrochemical, and magnetic characterizations.
