Summary: In this study, a series of bagasse-derived N-doped carbon catalysts were synthesized with the assistance of different activators to understand the relationship between activators, physicochemical properties, and electrocatalytic performance for the CO2RR. The properties of N-doped carbon catalysts, such as N-doping content, microstructure, and degree of graphitization, were found to be highly dependent on the type of activator used. Furthermore, the overall CO2RR performance of the synthesized electrocatalysts was determined by the overall surface chemistry, where the porosity and the degree of graphitization played significant roles.

Summary: In this study, samarium nanoparticles were synthesized and anchored onto the surface of a CuO:CoO nanostructure. The resulting nanostructures were characterized and investigated for their electrical and supercapacitive behavior. The exceptional properties of the Sm-x CuO:CoO nanostructures were attributed to the synergy of high charge mobility of the samarium nanoparticles, leading to significant variation in dielectric permittivity, current-voltage response, and capacitance-voltage behavior.

Summary: It was discovered that the addition of a chiral photochromic azo dopant to an achiral liquid crystal leads to a reversal of spontaneous and induced polarization in the tilted smectic C* phase and the orthogonal smectic A phase, respectively, under UV light illumination. This sign reversal effect, attributed to the different dipole moment components of the trans- and cis-isomers of the photochromic azo dopant, shows promising potential for applications in light-controlled photonic liquid crystal devices.

Summary: The study evaluated the wound healing efficacy of sandalwood bark-derived carbon nanospheres loaded with curcumin-embedded polyvinyl alcohol (PVA) nanofiber membranes. Carbon nanospheres (CNS) were prepared by pyrolyzing sandal wood bark powder, with field emission scanning electron micrographs and energy dispersive X-ray technique confirming the morphology and carbon content. Curcumin was loaded onto synthesized CNS and anchored in a PVA matrix via electrospun nanofiber fabrication. The prepared PVA/CNS-curcumin nanofiber membranes showed efficient wound closure and better antimicrobial activity than control membranes.
