Correlation between organic residuals of green synthesized nanoparticles and resistive switching behavior.

In this work, ZnO nanoparticles (NPs) are synthesized using avocado seed extract and annealed at different annealing temperatures from 400 to 800 °C. The morphology of the nanoparticles changes from poly shapes at 400 °C to spherical ones at 800 °C, and particle sizes increase from ∼42 nm to ∼128 nm. The Ag/ZnO@400/FTO memory device exhibits stable resistive switching over 100 cycles and a resistance window of approximately 150.

Promoted Hydrogen Peroxide Production from Pure Water on g-CN with Nitrogen Defects Constructed through Solvent-Precursor Interactions: Exploring a Complex Story in Piezo-Photocatalysis.

Hydrogen peroxide (HO) production via oxygen (O) reduction reaction (ORR) in pure water (HO) through graphitic carbon nitrides (g-CN)-based piezo-photocatalysts is an exciting approach in many current studies. However, the low Lewis-acid properties of g-CN limited the catalytic performance because of the low O adsorption efficacy. To overcome this challenge, the interaction of g-CN precursors with various solvents are utilized to synthesize g-CN, possessing multiple nitrogen-vacant species via thermal shocking polymerization.

Simultaneously Utilizing Excited Holes and Electrons for Piezoelectric-Enhanced Photoproduction of HO from S-Scheme 2D S-Doped VO/g-CN Nanostructures.

2D/2D step-scheme (S-scheme) piezo-photocatalysts for the production of fine chemicals, such as hydrogen peroxide (HO), have attracted significant attention of global scientists owing to the efficiency in utilizing surface piezoelectric effects from 2D materials to overcome rapid charge recombination in photocatalytic processes. In this research, we reported the fabrication of 2D S-doped VO deposited on 2D g-CN to produce HO via the piezo-photocatalytic process with high production yields at 20.19 mmol g h, which was 1.

Enhancement of antibacterial activities of green synthesized-CuO/ZnO nanocomposites using Boehmeria nivea leaf extract.

This study investigated CuO and ZnO nanoparticles and CuO/ZnO nanocomposites in a friendly environment with a low-cost and renewable biosynthesis method. This approach involved using Boehmeria nivea leaf extract to facilitate the growth and formation of nanocomposites with performance-enhancing phytochemicals released during the co-precipitation process.
