Chemical and Resistive Switching Properties of Extract-Carboxymethyl Cellulose Composite: A Potential Active Layer for Biodegradable Memory Devices.

Biodegradable electronic devices play a crucial role in addressing the escalating issue of electronic waste accumulation, which poses significant environmental threats. In this study, we explore the utilization of a methanol-based extract of the plant blended with a carboxymethyl cellulose biopolymer to produce a biodegradable and environmentally friendly functional material for a resistive switching memory system using silver and tungsten electrodes. Our analyses revealed that these two materials chemically interact to generate a perfect composite with near semiconducting optical bandgap (4.

Acid-activated corn silk as a promising phytosorbent for uptake of Malachite green and Cd (II) ion from simulated wastewater: equilibrium, kinetic and thermodynamic studies.

Malachite green (MG) dye and cadmium metal ion are toxic pollutants that should be removed from aqueous environment. The recent study aimed to examine the adsorption behavior of MG dye and Cd (II) from wastewater onto low-cost adsorbent prepared by activating corn silk with nitric acid (ACS) and characterized by SEM, FTIR, XRD, BET and TGA. The optimum MG and Cd (II) adsorption was observed at pH 7 and pH 9 and maximum uptake of both pollutants was at 0.

Using visible light to activate antiviral and antimicrobial properties of TiO nanoparticles in paints and coatings: focus on new developments for frequent-touch surfaces in hospitals.

Unlabelled: The COVID-19 pandemic refocused scientists the world over to produce technologies that will be able to prevent the spread of such diseases in the future. One area that deservedly receives much attention is the disinfection of health facilities like hospitals, public areas like bathrooms and train stations, and cleaning areas in the food industry. Microorganisms and viruses can attach to and survive on surfaces for a long time in most cases, increasing the risk for infection.

Perceptions of Retired Nurses on Factors Preventing Younger Professional Nurses from Applying the Ethos of Ubuntu in Professional Care.

Introduction: Younger professional nurses are the future of the nursing profession and they receive the baton from older and retired nurses to continue the profession in good light. Ubuntu is an African philosophy that is embedded in caring ethics and it is viewed as a core value of the nursing profession and is highly valued by older nurses.

Objective: We explored the perceptions of retired nurses on factors that prevent younger professional nurses from applying the ethos of Ubuntu in professional care.

Kinetic Study of Azobenzene-4,4'-dicarboxylic Acid and Aluminium and Zirconium Based Azobenzene-4,4'-dicarboxylate MOFs.

Metal organic frameworks (MOFs) are porous hybrid crystalline materials that consist of organic linkers coordinated to metal centres. The - isomerisation kinetics of the azobenzene-4,4'-dicarboxylic acid (AZB(COOH)) precursor, as well as the Al (Al-AZB)- and Zr (Zr-AZB)-based MOFs with azobenzene-4,4'-dicarboxylate linkers, are presented. The photo-isomerization in the MOFs originates from singly bound azobenzene moieties on the surface of the MOF.
