Dr Joseph George Davidson FRSE (February 7, 1892 – October 9, 1969) was an American chemist and inventor. Life Davidson was born February 7, 1892, in New York City, a son of John Wellington and Theresa (Gahan) Davidson. The family moved to California when he was an infant. He received his bachelor of arts degree in chemistry in 1911 from the University of Southern California, and subsequently a master of arts in chemistry in 1912. He subsequently received a doctorate (PhD) in chemistry from Columbia University in 1918. During World War I he was commissioned in the US Army as a 2nd Lieutenant in the Chemical Warfare Service (largely connected with the development of mustard gas), but with his role being connected more closely to mines, in the Bureau of Mines in Pittsburg. During World War II, he headed Union Carbide's subcontract to carry out the gaseous diffusion separation of uranium in Oak Ridge, Tennessee, which produced the fissile material for the first atomic bomb.

Atomic Bomb
A nuclear weapon is an explosive device that derives its destructive force from nuclear reactions, either fission (fission bomb) or a combination of fission and fusion reactions (thermonuclear bomb), producing a nuclear explosion. Both bomb types release large quantities of energy from relatively small amounts of matter. The first test of a fission ("atomic") bomb released an amount of energy approximately equal to . The first thermonuclear ("hydrogen") bomb test released energy approximately equal to . Nuclear bombs have had yields between 10 tons TNT (the W54) and 50 megatons for the Tsar Bomba (see TNT equivalent). A thermonuclear weapon weighing as little as can release energy equal to more than . A nuclear device no larger than a conventional bomb can devastate an entire city by blast, fire, and radiation. Since they are weapons of mass destruction, the proliferation of nuclear weapons is a focus of international relations policy. Nuclear weapons have been deployed ...

Carthusians
The Carthusians, also known as the Order of Carthusians ( la, Ordo Cartusiensis), are a Latin enclosed religious order of the Catholic Church. The order was founded by Bruno of Cologne in 1084 and includes both monks and nuns. The order has its own rule, called the ''Statutes'', and their life combines both eremitical and cenobitic monasticism. The motto of the Carthusians is , Latin for "The Cross is steady while the world turns." The Carthusians retain a unique form of liturgy known as the Carthusian Rite. The name ''Carthusian'' is derived from the Chartreuse Mountains in the French Prealps: Bruno built his first hermitage in a valley of these mountains. These names were adapted to the English ''charterhouse'', meaning a Carthusian monastery.; french: Chartreuse; german: Kartause; it, Certosa; pl, Kartuzja; es, Cartuja Today, there are 23 charterhouses, 18 for monks and 5 for nuns. The alcoholic cordial Chartreuse has been produced by the monks of Grande Chartreuse sinc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Arlington, Vermont
Arlington is a town in Bennington County, Vermont, United States. The population was 2,457 at the 2020 census. History The town of Arlington was chartered July 28, 1761, by New Hampshire Governor Benning Wentworth, as part of the New Hampshire Grants. In 1777, Arlington became the first capital of the Vermont Republic. Among the first settlers in Arlington were Captain Jehiel Hawley and his family, who had settled there by 1764. They were Anglicans and had fled Roxbury, Connecticut, because of the oppressive requirements of the established Congregational church. At a Proprietor's meeting in 1764, the town voted to give of land to any man who would set up a gristmill in what is now East Arlington. This offer was accepted by Remember Baker (first cousin of Ethan Allen), who built a grist and sawmill. In the years leading up to the American Revolution, both New York and New Hampshire laid claim to lands comprising current-day Vermont. The Province of New York began to grant la ...

Safety Glass
Safety glass is glass with additional safety features that make it less likely to break, or less likely to pose a threat when broken. Common designs include toughened glass (also known as tempered glass), laminated glass, and wire mesh glass (also known as wired glass). Wire mesh glass was invented by Frank Shuman. Laminated glass was invented in 1903 by the French chemist Édouard Bénédictus (1878–1930). These three approaches can easily be combined, allowing for the creation of glass that is at the same time toughened, laminated, and contains a wire mesh. However, combination of a wire mesh with other techniques is unusual, as it typically betrays their individual qualities. In many developed countries safety glass is part of the building regulations making properties safer. Toughened glass Toughened glass is processed by controlled thermal or chemical treatments to increase its strength compared with normal glass. Tempering, by design, creates balanced internal stre ...

Pickling Inhibitors
Pickling is the process of preserving or extending the shelf life of food by either anaerobic fermentation in brine or immersion in vinegar. The pickling procedure typically affects the food's texture and flavor. The resulting food is called a ''pickle'', or, to prevent ambiguity, prefaced with ''pickled''. Foods that are pickled include vegetables, fruits, meats, fish, dairy and eggs. Pickling solutions that are typically highly acidic, with a pH of 4.6 or lower, and high in salt, prevent enzymes from working and micro-organisms from multiplying. Pickling can preserve perishable foods for months. Antimicrobial herbs and spices, such as mustard seed, garlic, cinnamon or cloves, are often added. If the food contains sufficient moisture, a pickling brine may be produced simply by adding dry salt. For example, sauerkraut and Korean kimchi are produced by salting the vegetables to draw out excess water. Natural fermentation at room temperature, by lactic acid bacteria, produc ...

Antiknock Agent
An antiknock agent is a gasoline additive used to reduce engine knocking and increase the fuel's octane rating by raising the temperature and pressure at which auto-ignition occurs. The mixture known as gasoline or petrol, when used in high compression internal combustion engines, has a tendency to knock (also called "pinging" or "pinking") and/or to ignite early before the correctly timed spark occurs (''pre-ignition'', refer to engine knocking). Notable early antiknock agents, especially Tetraethyllead, added to gasoline included large amounts of toxic lead. The chemical was responsible for global negative impacts on health, and the phase out of leaded gasoline from the 1970s onward was reported by the UN to be responsible for $2.4 trillion in annual benefits, 1.2 million fewer premature deaths, higher overall intelligence and 58 million fewer crimes," the United Nations Environmental Programme said. Some other chemicals used as gasoline additives are thought to be less toxic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lacquers
Lacquer is a type of hard and usually shiny coating or finish applied to materials such as wood or metal. It is most often made from resin extracted from trees and waxes and has been in use since antiquity. Asian lacquerware, which may be called "true lacquer", are objects coated with the treated, dyed and dried sap of ''Toxicodendron vernicifluum'' or related trees, applied in several coats to a base that is usually wood. This dries to a very hard and smooth surface layer which is durable, waterproof, and attractive in feel and look. Asian lacquer is sometimes painted with pictures, inlaid with shell and other materials, or carved, as well as dusted with gold and given other further decorative treatments. In modern techniques, lacquer means a range of clear or pigmented coatings that dry by solvent evaporation to produce a hard, durable finish. The finish can be of any sheen level from ultra matte to high gloss, and it can be further polished as required. Lacquer finishes ...

Leo Baekeland
Leo Hendrik Baekeland (November 14, 1863 – February 23, 1944) was a Belgian chemist. He is best known for the inventions of Velox photographic paper in 1893, and Bakelite in 1907. He has been called "The Father of the Plastics Industry" for his invention of Bakelite, an inexpensive, non-flammable and versatile plastic, which marked the beginning of the modern plastics industry. Early life Leo Baekeland was born in Ghent, Belgium, on November 14, 1863, the son of a cobbler, Charles Baekeland, and a house maid, Rosalia Merchie. His siblings were: Elodia Maria Baekeland; Melonia Leonia Baekeland; Edmundus Baekeland; Rachel Helena Baekeland and Delphina Baekeland. He told ''The Literary Digest'': "The name is a Dutch word meaning 'Land of Beacons.'" He spent much of his early life in Ghent, Belgium. Proudly, he graduated with honours from the Ghent Municipal Technical School and was awarded a scholarship by the City of Ghent to study chemistry at the Ghent University, whi ...
