Facile synthesis of copper oxide nanoparticles (CuONPs) using green method to promote photocatalytic and biocidal applications

Facile Microwave-Assisted Hydrothermal Synthesis of Copper Oxide Nanoneedle Arrays for Practical Biomedical Applications

“…The in-vitro anti-inflammatory efficacy (inhibition of protein denaturation) was evaluated based on previous reports [ 14 , 15 ]. Typically, 50 μL of as-prepared CuO NAs solution was diluted with 450 μL of 5% weight/volume bovine serum albumin (BSA) protein before being incubated at 37 °C for 20 minutes and then heated at 60 °C for 3 minutes.…”

Composite membranes based on polyvinyl alcohol and lamellar solids for water decontamination

“…Composite or matrix membranes have been recently shown to produce interesting results in removing environmental pollutants. 28,29 In order to find new solutions in the field of water purification, we have developed low cost and ecofriendly composite membranes based on PVA and lamellar solids by a solution casting method. The lamellar solids chosen were: layered double hydroxides (LDHs) and zirconium phosphate (a-ZrP); the idea was to combine their abilities in order to remove from water both the most dangerous heavy metals (Pb 2+ , Cr 3+ , and Ni 2+ ) and DS as a model drug.…”

Nanofibers Loaded with Nonthermal Nitrogen Plasma-Treated g-C3N4 for Efficient Visible Light-Driven Photodegradation of Omethoate

“…Photocatalytic degradation methods, which can be directly driven by sunlight, are gaining more and more attention compared to physical adsorption methods with higher costs and time-consuming microbial degradation methods. − Some transition metal compounds with good photocatalytic activity have been used for the photocatalytic degradation of pesticides. − However, these photocatalysts often only utilize a relatively small portion of the ultraviolet spectrum in sunlight, and there is also a risk of causing secondary metal contamination of agricultural products. , In recent years, as a visible light-induced metal-free semiconductor material, graphitic carbon nitride (g-C 3 N 4 ) and its derivatives have received increasing attention in the field of photocatalytic degradation of organic pesticides due to their many advantages. , g-C 3 N 4 is considered a nontoxic and biocompatible material that can be easily synthesized from readily available urea at low cost, which means it can be safely used for postharvest processing of agricultural products without posing a threat to human health and the environment. , The band gap of g-C 3 N 4 is 2.7 eV, which has a high capacity for absorbing visible light (44%) as the main part of solar energy and separating/transferring photogenerated electron–hole pairs . At the same time, g-C 3 N 4 provides a photocatalysis active site that can effectively trigger the photocatalysis reaction in the process of photocatalysis, which is conducive to achieving enhanced photocatalysis efficiency. − …”
