Copper oxide, primarily referred to as CuO, is a black or brownish-black solid that belongs to the family of transition metal oxides. Its chemical formula signifies a one-to-one ratio of copper (Cu) and oxygen (O) atoms, forming a crystalline structure characterized by a monoclinic lattice system. This arrangement allows for unique electronic and optical properties, which are pivotal ... https://www.nanotrun.com/blog/exploring-the-versatile-world-of-copper-oxide-a-deep-dive-into-its-properties-applications-and-future-prospects_b1480.html
