Sequestration of Cr(VI) onto polyethyleneimine-derivatized cellulose and its effect on the enzymatic degradation and microbiome viability.

The extremely hazardous nature of Cr(VI) necessitates its sequestration in a sustainable and effective manner. Cellulose-derived materials, known for their eco-friendly properties, are widely employed in environmental remediation. To improve its adsorption capabilities for heavy metals, cellulose is often derivatized with moieties like amine, thiol, carboxylic acid, etc.

Recent Progress on Ligand-Protected Metal Nanoclusters in Photocatalysis.

The reckless use of non-replenishable fuels by the growing population for energy and the resultant incessant emissions of hazardous gases and waste products into the atmosphere have insisted that scientists fabricate materials capable of managing these global threats at once. In recent studies, photocatalysis has been employed to focus on utilizing renewable solar energy to initiate chemical processes with the aid of semiconductors and highly selective catalysts. A wide range of nanoparticles has showcased promising photocatalytic properties.
