Drug release potential of polyacrylamide grafted-Assam Bora rice polysaccharide graft copolymer (ABRS-g-PAM) as effective controlled release polymer.

The research focuses on the characterization and evaluation of drug delivery efficiency of a microwave-assisted, free-radical synthesized polyacrylamide-grafted Assam Bora rice starch (ABRS) graft copolymer (ABRS-g-PAM). Percentage grafting efficiency (% GE) and intrinsic viscosity were chosen as the optimization parameters. The optimized ABRS-g-PAM Grade Formulation 4 (GF4) was found to be the best grade.

Control of proton transport and hydrogenation in double-gated graphene.

The basal plane of graphene can function as a selective barrier that is permeable to protons but impermeable to all ions and gases, stimulating its use in applications such as membranes, catalysis and isotope separation. Protons can chemically adsorb on graphene and hydrogenate it, inducing a conductor-insulator transition that has been explored intensively in graphene electronic devices. However, both processes face energy barriers and various strategies have been proposed to accelerate proton transport, for example by introducing vacancies, incorporating catalytic metals or chemically functionalizing the lattice.

Understanding the charge transfer dynamics of the CuWS-CNT-FeOOH ternary composite for photo-electrochemical studies.

Ternary transition metal chalcogenide (CuWS) is a semiconductor with a band gap of 2.1 eV and could be a promising candidate for photoelectrochemical water splitting and solar energy conversion applications. Despite numerous reports on ternary transition metal chalcogenides, this semiconductor's ultrafast charge transfer dynamics remain unknown.
