In this study, zinc oxide (ZnO) nanoparticles were prepared and modified using a wet chemical method with different concentrations of Ag and Cu nanoparticles. The objective was to improve the mechanical, optical, and antibacterial properties of the coated paper by using the prepared pigments. The long-term antimicrobial effects of the coated paper were evaluated over 25 years.

Article Synopsis
  • Microbial combating, particularly through innovative strategies, is a crucial area of research, leading to the development of a new combined chemo- and photodynamic delivery system using zinc oxide nanoparticles (ZnO NPs) and other agents.
  • The engineered nanoformulation, ZnO@ALG-POR/BER, showcased significantly better loading capacity and antimicrobial effectiveness when paired with laser treatment compared to traditional methods, achieving complete suppression of bacterial and fungal growth.
  • Additionally, the cytotoxicity study indicated that these nanoformulations, especially ZnOBER@ALG-POR, demonstrated moderate biocompatibility with human retinal cells, paving the way for potential applications in medical treatments.

Designing highly adsorptive materials for wastewater treatment via facile approaches is still challenging. To boost the recovery of heavy metals from wastewater, surface and structure modification are considered a successful route. Herein, we report the design of ZnO nanoparticles by a simple thermal decomposition method followed by grafting Cu nanoparticles (Cu NPs) over the ZnO surface.

Electrocatalytic CO reduction reaction (CO RR) to multi-carbon products (C ) in acidic electrolyte is one of the most advanced routes for tackling our current climate and energy crisis. However, the competing hydrogen evolution reaction (HER) and the poor selectivity towards the valuable C products are the major obstacles for the upscaling of these technologies. High local potassium ions (K ) concentration at the cathode's surface can inhibit proton-diffusion and accelerate the desirable carbon-carbon (C-C) coupling process.
