In this work, graphene layers on SiO2/Si substrate have been chemically decorated by radio frequency hydrogen plasma. Hydrogen coverage investigation Raman spectroscopy and micro-X-ray photoelectron characterization demonstrates that the hydrogenation of single layer is much less feasible than bilayer multilayer graphene. Both dehydrogenation process are controlled corresponding energy barriers, which show significant dependence number layers. The extent carbon atoms in can be manipulated...

Abstract Cutaneous wound healing, especially diabetic is a common clinical challenge. Reactive oxygen species (ROS) and bacterial infection are two major detrimental states that induce oxidative stress inflammatory responses impede angiogenesis healing. A derivative of the metabolite itaconate, 4‐octyl itaconate (4OI) has attracted increasing research interest in recent years due to its antioxidant anti‐inflammatory properties. In this study, 4OI‐modified black phosphorus (BP) nanosheets...
