The semiconductor used here is zinc oxide (zincite), which is obtained by taking a strip of zinc and heating it with a blow torch. This creates spots of zinc oxide on the strip, which can then be ...

On the shelves of makeup counters and drugstores sits an array of foundations in various olive, ivory, and fair shades. But ...

Metal oxide nanoparticles, such as titanium dioxide (TiO2), zinc oxide (ZnO), and cerium oxide (CeO2), are widely used as catalysts for various chemical reactions, including photocatalysis, water ...

chemical reactions are often needed to remove other elements that might contaminate it. Zinc mostly occurs as sulfide ores, which are heated in air to convert them to zinc oxide. Molten close ...
