Iridium metal proved to destroy cancer cells

Recently, the Physicists Network reported that an international collaborative study between the University of Warwick and Sun Yat-sen University in China showed that cancer cells can be targeted and destroyed by metal iridium. The heavyweight study was published in the latest issue of Willie Applied Chemistry. Iridium was first discovered in 1803 and, like the platinum group, it is the most corrosion-resistant metal in the world. Its melting point exceeds 2400 ° C and is uncommon on Earth, but abundant [...]

Three-dimensional covalently attached sp2 hybrid graphite micropipes enhance the cycling stability of lithium metal negative

Lithium metal is considered as the most ideal lithium battery anode material due to its extremely high capacity (theoretical specific capacity of 3860 mA h g-1) and low potential (-3.040 V vs. standard hydrogen electrode). However, unlike graphite or silicon negative electrodes that achieve energy storage by forming lithium-based compounds, metallic lithium negative electrodes store energy by deposition / delamination of lithium at the electrode / electrolyte interface, which causes the lithium metal to react electrochemically Almost infinite volume [...]

The study found that vanadium dioxide ultra low thermal conductivity, “break” the laws of physics

Recently, a scientific study led by Wu Junqiao of the American Chinese Science Prize found that vanadium dioxide material in the conductive, the heat generated is very small, much lower than the Weidmann – Franz law is expected to break the classic laws of physics. The scientific discovery, published in the January 27 issue of Science, will bring a wider range of applications, such as a thermoelectric system that converts waste heat from engines and equipment into electrical energy. Weidman [...]

Research status of strontium titanate

Currently, various electronic instruments, home audio and video equipment and microcomputer, etc., in order to prevent the equipment from the external power supply cord, transmission of noise and signal lines or air surge voltage, as well as the human body electrostatic factors lead to wrong operation or semiconductor devices are broken down, is the use of ZnO varistor for protection. However ZnO varistor is purely resistive element, although has good pressure sensitive features, but because of the small dielectric constant, [...]

Preparation and properties of lanthanum zirconate and thermal barrier coatings

Thermal barrier coating is the most advanced high temperature alloy surface protective coating technology. It is widely used in aviation, aerospace, automobile and large thermal power generation industries. Especially with the gas turbine/aircraft engine towards the direction of high efficient development, on the performance of the ceramic material demand is higher and higher, traditional Y2O3 stable ZrO2 (YSZ) material is hard to meet the demand of high performance, study can replace YSZ used in high temperature thermal barrier coating [...]

Material Properties and Application of Gallium Nitride

Material properties GaN is a very stable compound, but also a hard high melting point material, the melting point of about 1700 ℃, GaN has a high degree of ionization, in the Ⅲ-Ⅴ compounds is the highest (0.5 or 0.43). At atmospheric pressure, GaN crystals are generally hexagonal wurtzite structures. It has 4 atoms in a cell, and the atomic volume is about half that of GaAs. Because of its high hardness, but also a good coating protection materials. Chemical properties At [...]

Morita Chemical plans to build a new lithium hexafluorophosphate plant in China

Recently, Japan’s Morita Chemical said the company plans to 2018 its factory in China’s lithium hexafluorophosphate production capacity increased to 7,500 tons / year, an increase of 5 percent. In addition, Morita Chemical also plans to build a new plant for lithium hexafluorophosphate in Taixing City, Jiangsu Province. Matsuda New Energy Materials (Zhangjiagang) Co., Ltd. is located in Zhangjiagang City, Jiangsu Province. It is jointly funded by Sumitomo Chemical Co., Ltd. and Sumitomo Corporation and Sumitomo Corporation (China) Co., Ltd. [...]

Ternary battery consumption in 2018 full beyond the lithium iron phosphate battery

The development of new energy electric vehicles to promote the demand for electric vehicles in the Tesla-based electric car after the rise of the international traditional car prices have joined the new energy vehicles in the field, according to the manufacturers planning, the global new energy vehicles in 2020 Production will reach 12 million, corresponding to the global demand for power 360GWh, the annual compound growth rate of 67.9%. In this context, the power battery business expansion speed, structural [...]

The mystery of vanadium dioxide is revealed

As an insulator, the vanadium dioxide material presents many competing phenomena when it is used as an insulator in relatively low temperature. However, since the study of vanadium dioxide has been studied since the 1960s, this strange phase behavior has not been mastered. Scientists have uncovered a mystery that has puzzled the academic world for decades by studying the system of the vanadium dioxide (metal to insulator), the us scientist said Wednesday. University of Tennessee, a research associate, Alexander’s low [...]
