Vanadium dioxide — a revolutionary material for the future electronics industry

Because of its unique properties, vanadium dioxide has become an ideal choice to replace silicon for a new generation of low-power electronic devices. Swiss researchers recently demonstrated the application of vanadium dioxide to aerospace communications (600677) systems to achieve programmable rf electronics, highlighting the oxide’s potential. Vanadium dioxide has phase transition characteristics and forms that can be converted between an insulator and a metal, acting as an insulator at room temperature and as a metal conductor above 68 degrees Celsius. [...]

Hydroxyapatite-“Stand-in” for New Century Bone

Due to the effects of diseases, aging, and frequent traffic accidents, the number of cases of bone injury has increased year by year. According to statistics, there are 3 million orthopedic cases in China every year, so the demand for bone substitute materials is increasing. In recent years, bone substitute materials represented by hydroxyapatite have gradually become the darlings of clinical application. Hydroxyapatite is the main component of vertebrate bones and teeth, and has good biological activity and biocompatibility. Compared [...]

The technology of industrialized production of nanometer copper powder has developed by Chinese manufacturer

The bulk application of nanometer copper powder in the market is based on the cost. At present, the high cost cannot realize the mass application, and the reason for the high cost is that the industrial production of ordinary equipment cannot be realized. Therefore, the first problem we solved is to use ordinary conventional equipment to realize the industrial production of nanometer copper powder. If the cost problem is not solved, even the preparation of high purity, ultra-fineness, narrow [...]

Laser technology opens up a new way to synthesize quantum dots

Recently, professor duhiwen’s team developed a new process for synthesizing monodisperse quantum dots, which is environmentally friendly and efficient. The results were published in Nature Communications, which is the world’s first report on synthesizing monodisperse quantum dots by physical method. Quantum dots, also known as semiconductor nanocrystals, are nanoparticles made up of ii-vi or iii-v elements. Quantum dot size, generally between 1 ~ 10 nm, due to the electrons and holes is strongly restricted in small volume, the quantum dot [...]
