Published: April 15, 2023

Abstract Due to global aging problems, the rising number of patients suffering from chronic or hard‐to‐heal acute wounds imposes a significant burden on healthcare systems. Wound healing is complicated and dynamic physiological process with distinct molecular cellular levels at each phase. Despite numerous strategies advanced wound dressings being developed, successful management through smart dressing materials that can adapt changing microenvironments address needs different stages remains big challenge. Over last decade, hydrogel‐based have emerged as one most potent biomaterials for treatment favorable biological characteristics high potential active intervention during wound‐curing process. In current contribution, we present recent progress in hydrogel regulate release therapeutics response external stimuli (such light) well endogenous changes environments (e.g., temperature, pH, glucose, reactive oxygen species) facilitate healing. We also introduce cutting‐edge technologies intelligent “sense‐and‐treat” combination built‐in sensors sensing molecules responsive hydrogels, which enable real‐time monitoring conditions prompt on‐demand therapy.

Recent advances in graphene-based phase change composites for thermal energy storage and management

Nano Materials Science, Journal Year: 2023, Volume and Issue: 6(2), P. 115 - 138

Published: Sept. 11, 2023

Energy storage and conservation are receiving increased attention due to rising global energy demands. Therefore, the development of materials is crucial. Thermal (TES) systems based on phase change (PCMs) have in prominence over past two decades, not only because their outstanding heat capacities but also superior thermal regulation capability. However, issues such as leakage low conductivity limit applicability a variety settings. Carbon-based graphene its derivatives can be utilized surmount these obstacles. This study examines recent advancements graphene-based composites (PCCs), where nanostructures graphene, oxide (GO), functionalized graphene/GO, aerogel (GA) incorporated into PCMs substantially enhance shape stability that could translated better capacity, durability, temperature response, thus boosting attractiveness for TES systems. In addition, applications PCCs various disciplines, buildings, solar utilization, battery management, discussed summarized.
