The crystal material called perovskite can be used to make ultra-efficient photovoltaic cells. Researchers are also exploring the potential of this material in transistors and LED lighting. The most promising one may be an X-ray detector. Dozens of research groups around the world are exploring this field, and major X-ray imaging manufacturers including Samsung and Siemens are considering using perovskite as the next generation machine. Compared to existing X-ray imagers, detectors based on perovskite compounds are more sensitive and consume less power. A laboratory prototype using perovskite demonstrates that its efficiency is at least 100 times that of traditional equipment. Jinsong Huang of Chapel Hill University in North Carolina predicts that perovskite detectors will open up new applications for X-rays, such as portable machines that work on batteries.
Nickel-based alloy wire owns good resistance to high reactive gases, caustic resistance medium and acid corrosion performance, and also owns high strength, good capability of shaping, hot and cold forming and welding deformation. Therefore it is widely used in petroleum chemical industry, metallurgy, atomic energy, ocean development, aviation, aerospace to solve the problem that general industry, stainless steel and other metals, non-metallic materials engineering corrosion problems could not be solved,it is a very important kind of corrosion resistant metal materials. Nickel based alloys are nickel based alloys that contain alloy elements and which can be resistant to corrosion in a number of media. To classify the chemical composition characteristics, mainly nickel, nickel copper alloy, nickel alloy, nickel chromium molybdenum (Nie Mutie) (iron nickel alloy), nickel chromium molybdenum (including Ni Cr Mo alloy and Ni Cr Mo Cu alloy) and nickel iron chromium (both iron nickel alloy) and other types of. Pure nickel welding wire ERNi-1 for welding of 200, 201 nickel alloy and nickel plated steel plate; steel and nickel dissimilar materials welding; steel surface surfacing.
