According to the "Asahi Shimbun," Japan reported on August 2, the Shibaura University of Technology Professor Shirayuki Yamashita and others have recently developed a technology that uses microorganisms to recover rare metals selenium contained in industrial wastewater. Because the collected selenium will be available as a resource, these technologies will be able to be commercialized. It is reported that selenium is a rare metal contained in a small amount of copper ore, which can be used as a raw material for solar panels, and can also be used for the coloring and decoloring of glass. Once dissolved in water, it will be toxic, and excessive intake can cause symptoms such as neurological disorders. According to reports, Prof. Yamashita et al. found microorganisms that can convert selenate and selenite into selenium in the sludge near the selenium-refining plant. If such microorganisms are cultivated in industrial wastewater, 78.8% of selenium can be recovered. (Internship compilation: Yang Jie reviewer: Wang Huan)
We can manufacture various shape and special material optical lens.The coating for lenses not only the normal BBAR coating,but also including dichroic coating and super broad band antireflective coating.
Plano-Convex (PCX) Lenses have a positive focal length, making them ideal for collecting and focusing light in imaging applications. They are also useful in a variety of applications involving emitters, detectors, lasers, and fiber optics. Coated versions have optimum light transmission. Available in a wide variety of diameters and focal lengths.
The coated lenses can be utilized in a host of optics and photonics applications, including biotech instruments such as DNA sequencers and polymerase chain reaction (PCR) testing platforms.
