Not only is there a frightening epidemic in 2020, but it is also the first year of commercial 5G. 5G commercial use attracted more attention in 2019. The 5G technology led by the Huawei Group has made breakthroughs in multiple technical issu
Cupric oxide (CuO), having a narrow bandgap of 1.2 eV and various thermophysical properties, is recently attractive in many fields, such as energy conversion, optoelectronic devices, and catalysts. Compared with bulk material, the advanced properties of CuO nanostructures have been demonstrated; however, the fact that these materials cannot yet be produced on a large scale is an obstacle to realizing the potential applications of this material. In this respect, chemical methods are efficient syn
Micro-powders come in many forms. Bismuth Oxide Powder One of the most flexible and practical. This oxide can be used to synthesize many compounds, such as those found in pharmaceuticals and biotechnology. It is a micro-powder with a high purity that can be used in analytical procedures. It is also useful in industry as a pigment filler. Because of its high granularity, it is possible to control the particle size and distribution in a wide range of industrial applications. Properties of the
Niobium carbide powder is a dark gray-brown powder with a cubic crystal structure and metallic luster. It is stable at a temperature of 1000 to 1100°C and rapidly oxidized to niobium pentoxide at a temperature above 1100°C.
