Summary: A novel aerogel-like wound dressing capable of sensing the progress of wound healing was developed. Anthocyanins extracted from red-cabbage were integrated into a carboxymethyl cellulose/polyvinyl alcohol composite to create a water-soluble direct dye. The resulting composite was freeze-dried to obtain the aerogel-like smart wound dressing, which demonstrated antibacterial and biochromic properties for monitoring wound healing. Colorimetric changes and UV-Vis absorption spectra were used to measure the effects of anthocyanin content on the diagnostic assay. The morphology, stiffness, air-permeability, and mechanical behavior of the wound dressing were analyzed using various methods.

Summary: Visible-light-driven photocatalytic water splitting is a promising approach for hydrogen generation. Onion-like carbon nano particles (OCNPs) isolated from diesel engine exhaust soot have shown strong capability for visible-light promoted hydrogen evolution. The high hydrogen evolution rate of OCNPs under visible light irradiation, comparable with literature values without dopants or co-catalysts, is attributed to the presence of optically active centers and a high sp(3)/sp(2) interface on the OCNPs surface, promoting the process of visible-light assisted photocatalytic water splitting. These waste derived OCNPs can serve as high-performance photocatalytic materials for visible light-to-hydrogen production, contributing to the goal of achieving clean energy.

Summary: In light of accelerated industrialization and the crisis of clean water, the treatment of wastewater, particularly the elimination of nitrophenols, is significant. In this study, low-cost and green carbon nano-onions (CNOs) synthesized from low-quality flaxseed oil showed high efficiency in removing nitrophenols from contaminated water. The adsorption of nitrophenols onto CNOs followed a Langmuir adsorption isotherm and pseudo-second-order kinetics, and the process was found to be spontaneous and exothermic. Furthermore, the CNOs demonstrated good recyclability and easy separation, making them highly applicable in wastewater treatment.
