January 25, Solar-driven photoelectrochemical PEC water splitting is an attractive approach to convert solar energy into chemical energy. Among many photoelectrode materials, crystalline silicon c-Si has drawn considerable attention because of its earth abundance, narrow bandgap, and suitable band edge position for hydrogen evolution reaction HER. However, c-Si suffers from low photovoltage generated from the solid-liquid junction. Various strategies, such as the construction of p-n homojunctions, metal-insulator-semiconductor MIS junctions and p-n heterojunctions, have been adopted to obtain high photovoltage. The MIS junctions have been the focus of attention in PEC water splitting due to their simple fabrication and the potential to achieve higher efficiencies than p-n junctions.
8.2. Absorption Cooling
Skin absorption is a route by which substances can enter the body through the skin. Along with inhalation , ingestion and injection , dermal absorption is a route of exposure for toxic substances and route of administration for medication. Absorption of substances through the skin depends on a number of factors, the most important of which are concentration , duration of contact, solubility of medication, and physical condition of the skin and part of the body exposed. Skin percutaneous, dermal absorption is the transport of chemicals from the outer surface of the skin both into the skin and into circulation.
Active absorption refers to the absorption of water by roots with the help of adenosine triphosphate , generated by the root respiration : as the root cells actively take part in the process, it is called active absorption. The active absorption is carried out by two theories; active osmotic water absorption and Active non-osmotic water absorption. In this process, energy is not required. Active absorption is important for the plants.
