Kazuki Yoshimura, Energy Control Thin Film Group, the Materials Research Institute for Sustainable Development of the National Institute of Advanced Industrial Science and Technology, has developed a switchable mirror that uses a new switching method.

Space-Time Physics - Particles, fields & forces derived from 4 dimensional space-Switchable mirrors can be switched between a transparent state and a mirror state. Their use can yield energy-saving window glass that substantially reduces cooling loads by effectively blocking sunlight. The developed switchable mirror sheet uses new gasochromic switching that is completely different from conventional gasochromic switching methods. It can control the reflection of visible to near-infrared light at a switching speed about 20 times faster than that of conventional electrochromic switchable glass. The present development can solve the issues involved in bringing gasochromic switchable mirrors into practical use. Because the thickness of the thin film that controls light is about 1/10 that of conventional films, substantial reduction in production cost is expected. Details of this technology were exhibited and presented at Nano tech 2013, the 12th International Nanotechnology Exhibition and Conference, held from January 30 to February 1 at Tokyo Big Site in Koto-ku, Tokyo. Air conditioning accounts for about 30% of energy consumption at home and at work. A window is a building component that significantly affects energy consumption. Normal window glass transmits visible light as well as heat and reduces the effectiveness of insulation. Increasing the insulation value of windows is very effective in saving energy, and double-pane glass and low-e (low-emissivity) glass with high insulation values are becoming widely used. Switchable glass can control incoming and outgoing light and heat to increase energy-saving effects by insulating heat and blocking sunlight. Electrically controllable electrochromic glass is a typical type of switchable glass. Recently, in the United States, electrochromic glass with a tungsten oxide thin film as the switchable layer has been commercialized for building applications. However, inexpensive switchable glass is required to promote the widespread use.

Glass Inspection Systems - Industry proven solutions to reduce costs in flat glass manufacturing. All conventional electrochromic glass absorbs light to control light and therefore has a drawback; the temperature of the thin film rises and the film re-radiate heat into the room. If light could be controlled by reflection, then sunlight could be blocked more efficiently. Therefore switchable mirrors that can be switched between the transparent state and the mirror state are awaited. Since 2001, AIST has been conducting research and development of thin-film materials for switchable mirrors. It has installed actual-size window glass in a real building and has demonstrated that the glass can reduce the cooling load by more than 30% compared with conventional transparent double-pane window glass.

2012 County, Jiangxi tungsten industry realized main business income of 6.62 billion yuan, a year-on-year growth of 26.9%, the tungsten industry driving large-scale industrial growth by 7.5 percentage points, the tungsten industry has become the leading force to promote the county's economic development.

County tungsten mines is bigger and stronger tungsten industry further, first unified integration planning and promotion, to achieve the optimal allocation of resources, focus on strengthening of large enterprise groups with Jiangxi University of Science and Technology, the National Center for tungsten seized, city technology innovation center cooperation and scientific research institutes, and strive to improve the value-added products, to extend the industrial chain. Followed the growth of leading enterprises, World Rui focus on new materials, new materials Yuanchi Jiangxi Tungsten tungsten alloy strength leading enterprises have the potential to give support in the capital, water and electricity supply, policy, personnel. Give priority to the supply of raw materials, implement county optimal allocation of resources, and guide resources gathered to leading enterprises, and promote the industry bigger and stronger. At the same time, speed up scientific and technological innovation, the role of fiscal skillfully deflected to support enterprises to expand their reproduction and technology updates, transforming technological achievements, guide enterprises from the rough to the development of deep processing, take the science and technology, saving, environmentally friendly way of development. Currently, there are 10 million tungsten processing enterprises in the county the main business income tax exceeds four million.

Ganzhou, Jiangxi, the birthplace of China’s tungsten industry, which is known as “the capital of tungsten”.

In 1907, a German cleric found tungsten deposit in Huaxi Shan Mountain of Dayu county. The history of exploiting tungsten in China started in 1914 when people found large deposits of tungsten one after another in Zhongshao, Chongyi, and Daji shan Mountain in Quannan county. In 1931,Mao Zedong who was then the bank president and general manager of “ Chinese Tungsten Ore Enterprise” of Chinese-Soviet Republic, during his term of office, the mining quantity reached near to 8000 ton, creating a wealth worth of 6.2 million yuan, by which he was able to exchange large volume of drug, salt and arms. Tungsten has played an important role in breaking through the beleaguer and economic blockade arranged by KMT.

After the establishment of the People’s Republic of China, nine state-own mines, 16 local mines and over 20 collective mines were established in Ganzhou, Ganzhou became one of the most important producing areas of raw tungsten in China even the whole world. During which time, geologists ascertained that there were 106 tungsten mines with a storage of 1.17million tons, the producing area ranks No.2 in China in terms of reserve volume, but ranks top in term of the reserves of wolframite , the area accounts for 70% of like product in China and 60% in the world.  

According to the head of Geological Exploration Bureau of Ministry of Land and Resources, our country has made an unexpected achievement since we have launched the strategic action in prospecting, a batch of mineral deposits of world-scale storage have been found and ascertained.

It is reported that the strategic action of prospecting aiming at strengthening the energy security domestically is a national strategy. Two years after the action was enforced, our country has ascertained a super large sandstone-type uranium deposit in E'erduosi Basin(Known as Daying uranium deposit), and large mineral deposit of tungsten, molybdenum, nickel, while large deposits of new energy sources have been found in areas like Gansu, Xinjia.
