This study presents, for the first time, the comparison of behavior between two commonly found plant species, their extracts, and their major constituents (glucose and sucrose constituting over 70% of their dried extract) to synthesize zinc oxide (ZnO) nanoparticles (NPs) from zinc nitrate hexahydrate. The findings underscore the critical role of sugars as key constituents in facilitating this synthesis. This research demonstrates that the process can occur at relatively low temperatures (120°C). However, it necessitates a specific ratio of reactants to produce "clean" ZnO NPs. These findings offer significant insights into the optimization and control of the nanoparticle synthesis process.

The development of an efficient coating with comprehensive antimicrobial and anticorrosion properties for metals is crucial. The present study used a one-pot strategy to fabricate a high-performance nanocomposite coating of carboxylated nitrile butadiene rubber/cellulose nanofibers/zinc oxide (XNBR/CNF-ZnO), demonstrating excellent potential for application in the protection against metal corrosion. Eco-friendly CNF-ZnO nanomaterials, prepared using the in-situ generation method, were used as reinforcing fillers, while XNBR was used as the matrix material.

Analysis of glass-based artworks is important for authentication purposes. In recent years, there have been rapid advancements and improvements in the characterization of glass objects using different analytical approaches. The present study presents an interdisciplinary and multi-analytical authentication approach that provides useful tools and markers to unmask possible imitations, counterfeiting, and forgeries in Cultural Heritage glass beads by comparing the composition of historical and modern glass beads.

The crosstalk of transition metal ions between the metal oxide cathode and Zn anode restricts the practical applications of aqueous zinc-ion batteries (ZIBs). Herein, we propose a decoupled electrolyte (DCE) consisting of a nonaqueous-phase (N-phase) anolyte and an aqueous-phase (A-phase) catholyte to prevent the crosstalk of Mn2+, thus extending the lifespan of MnO2-based ZIBs. Experimental measurements and theoretical modelling verify that trimethyl phosphate (TMP) not only synergistically works with NH4Cl in the N-phase anolyte to enable fast Zn2+ conduction while block Mn2+ diffusion toward anode, but also modifies the Zn2+ solvation structure to suppress the dendrite formation and corrosion on Zn anode.
