Scanning electron microscope images of four samples of zinc oxide nanoparticles from different vendors, showing differences in size and shape. Zinc oxide nanoparticles are nanoparticles of zinc oxide (ZnO) that have diameters less than 100 nanometers. They have a large surface area relative to their size and high catalytic activity.
Zinc oxide is an inorganic compound with the formula Zn O.It is a white powder which is insoluble in water. ZnO is used as an additive in numerous materials and products including cosmetics, food supplements, rubbers, plastics, ceramics, glass, cement, lubricants, [12] paints, sunscreens, ointments, adhesives, sealants, pigments, foods, batteries, ferrites, fire retardants, semi conductors ...
ZnO is strongly oxidative, chemically stable, with enhanced photocatalytic activity, and has a large free-exciton binding energy. It is non-toxic, abundant, biocompatible, biodegradable, environmentally friendly, low cost, and compatible with simple chemical synthesis. ZnO faces limits to its widespread use in photocatalysis under solar radiation.

The optical bandgap of ZnO nanorod can be tuned by changing the morphology, composition, size etc. Recent years, [when?] ZnO nanorods have been intensely used to fabricate nano-scale electronic devices, including field effect transistor, ultraviolet photodetector, Schottky diode, and ultra-bright light-emitting diode (LED).
The NWS Bay Area said the warning was over for San Francisco at 6:07 a.m. And let the tornado warning expire at 6:15 a.m. The warning led to a flurry of social media posts from residents who were ...
