Shitagau Noguchi
was a Japanese entrepreneur who founded the Nichitsu ''zaibatsu''. Known as the father of electrochemical engineering in Japan, he invested heavily in the development of Korea and Manchukou in cooperation with the Imperial Japanese Army and Navy.Tokyo Shimbun, Aug. 9, 1999, p. 22 His company was dissolved under the American occupation after World War II, and its successor companies include the Chisso Corporation, and portions of Asahi Kasei, Sekisui Chemical Company, and Shin-Etsu Chemical. Biography Noguchi was born to a samurai class family in Kanazawa, Ishikawa Prefecture, Japan. He studied electrical engineering at the Tokyo Imperial University and was hired by Siemens in 1898. He designed Japan's first commercial production plant for Calcium carbide in Sendai in 1903. In 1906, two Germans, A.Frank and N. Caro, invented a new method to produce calcium cyanamide to be used a fertilizer. Noguchi learnt of this invention in a newspaper and realized that the method could be used ...

Electrical Engineering
Electrical engineering is an engineering discipline concerned with the study, design, and application of equipment, devices, and systems which use electricity, electronics, and electromagnetism. It emerged as an identifiable occupation in the latter half of the 19th century after commercialization of the electric telegraph, the telephone, and electrical power generation, distribution, and use. Electrical engineering is now divided into a wide range of different fields, including computer engineering, systems engineering, power engineering, telecommunications, radio-frequency engineering, signal processing, instrumentation, photovoltaic cells, electronics, and optics and photonics. Many of these disciplines overlap with other engineering branches, spanning a huge number of specializations including hardware engineering, power electronics, electromagnetics and waves, microwave engineering, nanotechnology, electrochemistry, renewable energies, mechatronics/control, and electrical m ...

Chugoku Electric Power
, trading as (Latin for "energy") is an electric utility with its exclusive operational area of Chūgoku region of Japan. It is the sixth largest by electricity sales among Japan's ten regional power utilities. It operates the Shimane Nuclear Power Plant. In 1982, Chugoku Electric Power Company proposed building a nuclear power plant near the island of Iwaishima, but many residents opposed the idea, and the island's fishing cooperative voted overwhelmingly against the plans. In January 1983, almost 400 islanders staged a protest march, which was the first of more than 1,000 protests the islanders carried out. Since the Fukushima nuclear disaster in March 2011 there has been wider opposition to construction plans for the plant.

Ammonium Sulphate
Ammonium sulfate (American English and international scientific usage; ammonium sulphate in British English); (NH4)2SO4, is an inorganic salt with a number of commercial uses. The most common use is as a soil fertilizer. It contains 21% nitrogen and 24% sulfur. Uses The primary use of ammonium sulfate is as a fertilizer for alkaline soils. In the soil the ammonium ion is released and forms a small amount of acid, lowering the pH balance of the soil, while contributing essential nitrogen for plant growth. The main disadvantage to the use of ammonium sulfate is its low nitrogen content relative to ammonium nitrate, which elevates transportation costs.Karl-Heinz Zapp "Ammonium Compounds" in ''Ullmann's Encyclopedia of Industrial Chemistry'', 2012, Wiley-VCH, Weinheim. It is also used as an agricultural spray adjuvant for water-soluble insecticides, herbicides, and fungicides. There, it functions to bind iron and calcium cations that are present in both well water and plant cells. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mitsubishi
The is a group of autonomous Japanese multinational companies in a variety of industries. Founded by Yatarō Iwasaki in 1870, the Mitsubishi Group historically descended from the Mitsubishi zaibatsu, a unified company which existed from 1870 to 1946. The company was disbanded during the occupation of Japan following World War II. The former constituents of the company continue to share the Mitsubishi brand and trademark. Although the group of companies participate in limited business cooperation, most famously through monthly "Friday Conference" executive meetings, they are formally independent and are not under common control. The four main companies in the group are MUFG Bank (the largest bank in Japan), Mitsubishi Corporation (a general trading company), Mitsubishi Electric and Mitsubishi Heavy Industries (both diversified manufacturing companies). History The Mitsubishi company was established as a shipping firm by Iwasaki Yatarō (1834–1885) in 1870 under the name ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Minamata, Kumamoto
is a city located in Kumamoto Prefecture, Japan. It is on the west coast of Kyūshū and faces Amakusa islands. Minamata was established as a village in 1889, re-designated as a town in 1912 and grew into a city in 1949. As of March 2017, the city has an estimated population of 25,310 and a population density of 160 persons per km². The total area is 162.88 km².

A local chemical plant was blamed for causing the disease by emitting untreated wastewater into Minamata Bay. Lately, Minamata has focused on becoming a model environmental city. In 1999, the city obtained the ISO 14001 certification for Environmental Management. In 2001, Minamata became an official Japanese Eco-town. In 2004 and 2005, Minamata won the Japanese Top Eco-City contest. Minamata environmental disaster History The city is best known as the former site of an environm ...

Hydroelectric Power
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Calcium Cyanamide
Calcium cyanamide is the inorganic compound with the formula CaCN2. It is the calcium salt of the cyanamide () anion. This chemical is used as fertilizer and is commercially known as nitrolime. It was first synthesized in 1898 by Adolph Frank and Nikodem Caro (Frank–Caro process). History In their search for a new process for producing cyanides for cyanide leaching of gold, Frank and Caro discovered the ability of alkaline earth carbides to absorb atmospheric nitrogen at high temperatures. Fritz Rothe, a colleague of Frank and Caro, succeeded in 1898 in overcoming problems with the use of calcium carbide and clarified that at around 1,100 °C not calcium cyanide but calcium cyanamide is formed in the reaction. In fact, the initial target product sodium cyanide can also be obtained from calcium cyanamide by melting it with sodium chloride in the presence of carbon: : CaCN2 + 2 NaCl + C → 2 NaCN + CaCl2 Frank and Caro developed this reaction for a large-scale ...
