The fuel cell is a proton exchange membrane fuel cell. It directly uses methanol aqueous solution or hydrogen as a fuel supply source to generate electricity. It has the characteristics of quick start at low temperature, environmental friendliness, and simple battery structure. It is an efficient green energy source.

Cadmium selenide nanocrystal is the most widely studied and most promising II-VI semiconductor nanocrystals. Due to its important nonlinear optical properties, luminescent properties and other physicochemical properties, it is considered as a material with great and widely application in the future.

Probably the most well-known outlet for tungsten alloys is the aerospace industry, where weights and counterweights are often required to be housed in restricted areas. With significant reductions in size possible, this in turn, leads to greater control of weight distribution. 

In some situation, we need some special things to add weight in sailboat. But the space for the special things usually very small. For example, the sailboats, if the sailboats weight is not enough, it can turn turtle easily, especially when moving in a wind weather. So, we need add some tungsten alloy counterweights into the sailboats to against the yawing when sailing forward.

Cesium tungsten bronze (Cs0.33 WO3) nano powder is a new functional materials, which has strong absorption and high transmittance ability in near infrared region (800-1200nm wavelength) and the visible region (380-780nm wavelength). It can be used as infrared transparent barrier.

Tungsten carbide alloy has special corrosion resistance, high hardness and compressive strength. It is called modern industrial teeth and plays an extremely important role in machinery, metallurgy, precision instruments and military industries.

Biomass is a renewable resource with abundant reserves, wide distribution, low price and carbon fixation function. It has the potential to replace fossil resources to produce hydrocarbon fuels and chemical products. In recent years, studies have found that biomass such as lignocellulose is mainly composed of cellulose, hemicellulose and lignin. After pretreatment, carbohydrate raw materials such as cellulose and glucose can be obtained, which can be used to produce high value-added chemicals and organisms’ oil.

According to Bloomberg News, Tesla CEO Elon Musk said in a conference call: Tesla has mastered the technology to reduce the amount of cobalt metal in lithium-ion batteries. The original words are: We think we can get Cobalt to almost nothing. Tesla is currently mass producing the Model 3, which is powered by a lithium-ion battery pack.

With the upcoming construction of the International Thermonuclear Experimental Reactor (ITER), the study of plasma-facing materials (PFM) used in ITER has become a popular and frontier research direction, as it is a key component of fusion reactor.

For many years, tungsten alloy has been the best choice for engineers and doctors regarding nuclear medicine. One key reason for this is the high density of tungsten alloy. In fact, it is more than 60% denser than lead, providing superior attenuation characteristics for x-ray and gamma radiation.
