Theodore Swann
Theodore Swann (September 6, 1886 – February 5, 1955) was an American industrialist and early leader of the chemical industry. He was described by one historian as "a flamboyant Birmingham mogul and New South industrialist." Hailing from east Tennessee, in his early working years, Swann was a power salesman for the Alabama Power Company. He established the Federal Phosphorus Company to produce concentrated phosphoric acid, mainly for use as a concentrated fertilizer, using a novel method to produce the acid from phosphate rock by heat treatment in an electric furnace. He later established the Swann Chemical Company, focused on production of PCBs for the emergent electrical industry. Swann Chemical Company operated a chemical manufacturing plant in Anniston, Alabama where PCBs were first made on an industrial scale after development of a new process under Swann's leadership. In 1920, Swann gave his engineers the challenge of creating a process by which PCBs, up to that time ver ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polychlorinated Biphenyl
Polychlorinated biphenyls (PCBs) are highly carcinogenic chemical compounds, formerly used in industrial and consumer products, whose production was banned in the United States by the Toxic Substances Control Act in 1979 and internationally by the Stockholm Convention on Persistent Organic Pollutants in 2001. They are organic chlorine compounds with the formula C12 H10−''x'' Cl''x''; they were once widely used in the manufacture of carbonless copy paper, as heat transfer fluids, and as dielectric and coolant fluids for electrical equipment. Because of their longevity, PCBs are still widely in use, even though their manufacture has declined drastically since the 1960s, when a host of problems were identified. With the discovery of PCBs' environmental toxicity, and classification as persistent organic pollutants, their production was banned by United States federal law in 1978, and by the Stockholm Convention on Persistent Organic Pollutants in 2001.

Fulgencio Batista
Fulgencio Batista y Zaldívar (; ; born Rubén Zaldívar, January 16, 1901 – August 6, 1973) was a Cuban military officer and politician who served as the elected president of Cuba from 1940 to 1944 and as its U.S.-backed military dictator from 1952 to 1959, when he was overthrown by the Cuban Revolution. Batista initially rose to power as part of the 1933 Revolt of the Sergeants, which overthrew the provisional government of Carlos Manuel de Céspedes y Quesada. Batista then appointed himself chief of the armed forces, with the rank of colonel, and effectively controlled the five-member "pentarchy" that functioned as the collective head of state. He maintained control through a string of puppet presidents until 1940, when he was elected president on a populist platform. He then instated the 1940 Constitution of Cuba and served until 1944. After finishing his term, Batista moved to Florida, returning to Cuba to run for president in 1952. Facing certain electoral defeat, ...

Monsanto
The Monsanto Company () was an American agrochemical and agricultural biotechnology corporation founded in 1901 and headquartered in Creve Coeur, Missouri. Monsanto's best known product is Roundup, a glyphosate-based herbicide, developed in the 1970s. Later the company became a major producer of genetically engineered crops. In 2018, the company ranked 199th on the Fortune 500 of the largest United States corporations by revenue. Monsanto was one of four groups to introduce genes into plants in 1983, and was among the first to conduct field trials of genetically modified crops in 1987. It was one of the top 10 US chemical companies until it divested most of its chemical businesses between 1997 and 2002, through a process of mergers and spin-offs that focused the company on biotechnology. Monsanto was one of the first companies to apply the biotechnology industry business model to agriculture, using techniques developed by biotech drug companies. In this business model, ...

Heat Treating
Heat treating (or heat treatment) is a group of industrial, thermal and metalworking processes used to alter the physical, and sometimes chemical, properties of a material. The most common application is metallurgical. Heat treatments are also used in the manufacture of many other materials, such as glass. Heat treatment involves the use of heating or chilling, normally to extreme temperatures, to achieve the desired result such as hardening or softening of a material. Heat treatment techniques include annealing, case hardening, precipitation strengthening, tempering, carburizing, normalizing and quenching. Although the term ''heat treatment'' applies only to processes where the heating and cooling are done for the specific purpose of altering properties intentionally, heating and cooling often occur incidentally during other manufacturing processes such as hot forming or welding. Physical processes Metallic materials consist of a microstructure of small crystals called ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Phosphate
In chemistry, a phosphate is an anion, salt, functional group or ester derived from a phosphoric acid. It most commonly means orthophosphate, a derivative of orthophosphoric acid . The phosphate or orthophosphate ion is derived from phosphoric acid by the removal of three protons . Removal of one or two protons gives the dihydrogen phosphate ion and the hydrogen phosphate ion ion, respectively. These names are also used for salts of those anions, such as ammonium dihydrogen phosphate and trisodium phosphate.
