Aoyama Aoyama, a visiting professor at the University of Tsukuba, Japan, recently released the results of his research at an international seminar hosted by Fukushima University. Said that the radioactive substance cesium 137 that entered the ocean in the 2011 Tokyo Electric Power Company’s Fukushima Daiichi nuclear power plant accident arrived on the west coast of the United States and traveled northward, passing by the Bering Sea, the northernmost part of the Pacific Ocean, returns to the northeastern coast of Japan in about 7 to 8 years.


Is Cesium Tungsten Bronze a Radioactive Substance?

Tungsten, also known as Wolfram, is a rare metal known for its highest melting point of all elements. In addition to excellent temperature resistance, the material also has strong abrasion resistance and chemical resistance. These good properties make it an ideal material for components that operate at extreme temperatures.


What Is the Best Material for X-ray Collimation – Tungsten Metal or Tungsten Alloy?

A collimator is a device used to transform the divergent light or other radiation from a point light source into a parallel beam, and also is an absorber device used to limit X-rays, gamma rays, or nuclear particle beams to the size and angular spread required for a specific application. Normally, special measurements in spectroscopy and geometric and physical optics require this kind of light collimation.

In recent years, photoelectrochemical (PEC) water splitting has attracted people's attention, and it is considered to have potential applications in solar energy conversion. The effectiveness of solar energy conversion mainly depends on the structure of the photoelectrode. In addition, nanostructured photoelectrodes and surface porosity have additional advantages in in improving the efficiency since they exhibit unique properties of light-harvesting, chemical stability, active surface area, and charge separation.


Nano-sized Tungsten Carbide Fabricated Using Violet Tungsten Oxide

Cemented carbide is a kind of composite material prepared with tungsten carbide (WC) powder, which is widely used in cutting tools, drilling, and other technical fields due to its high hardness, high wear resistance, high strength and good toughness. In recent years, nano tungsten carbide powder is more required than ever due to the development of nanocrystalline cemented carbide.


Sodium Tungsten Bronze in Energy-Saving Glass

Electrochromic devices such as smart windows have received extensive attention from researchers in related fields in the materials industry. Tungsten trioxide (WO3) is an n-type semiconductor and a promising material due to its high transparency, good coloration efficiency, and low response times. The electrochromic performance of WO3 depends strongly on its particle size, morphology, and structure. However, low electrical conductivity of WO3 can give rise to poor electrochromic performance of the device. 


Synthesis of Micro-Spherical Tungsten-Molybdenum Alloy

In recent years, tungsten-molybdenum (W-Mo) alloys have attracted great interest as high-temperature materials for various applications. W-Mo alloy has excellent performance in preventing corrosion of molten zinc, and can be used at higher temperatures than molybdenum or molybdenum alloys. It is used for zinc liquid temperature measuring tube, zinc liquid pump rotor, and some corrosion-resistant parts of zinc smelting furnace. Because of its high melting point, ablation resistance, and flame retardancy to solid particles. tungsten-molybdenum alloy can also be used for the air rudder and protective cover of solid rocket motors. In addition, it is also used in the production of stirring tools in the glass industry, the manufacture of thin film transistors, the sputtering target for flat screen coating and the treatment of molten metal.
