Ray Wendland
Ray Theodore Wendland (July 11, 1911 – November 30, 1986) was an American experimental chemist and academician. Education Wendland was born in Minneapolis, Minnesota in July, 1911, and educated at Carleton College in Northfield, Minnesota, receiving a B.A. degree in chemistry in 1933. From there, he matriculated to Iowa State University, Ames, Iowa, to pursue graduate studies. He was awarded a Ph.D. from that institution in 1937. Postdoctoral appointments followed at Carnegie Technical Institute (now Carnegie Mellon University) in Pittsburgh, Pennsylvania, and the University of Minnesota in Minneapolis, centering on the refinement of rubber production under the auspices of the U.S. War Production Board. This work continued through World War II and contributed to the effectiveness of the war effort on the homefront. Academic career Between 1945 and 1955, Wendland served on the faculties of Coe College in Cedar Rapids, Iowa; Lehigh University in Bethlehem, Pennsylvania; an ...

Academician
An academician is a full member of an artistic, literary, engineering, or scientific academy. In many countries, it is an honorific title used to denote a full member of an academy that has a strong influence on national scientific life. Accordingly, within systems such as the Academy of Sciences of the USSR, the title grants privileges and administrative responsibilities for funding allocation and research priorities. History Historically, the meaning for the title of ''Academician'' follows the traditions of the two most successful early scientific societies: either the Royal Society, where it was an honorary recognition by an independent body of peer reviewers and was meant to distinguish a person, while giving relatively little formal power, or the model of the French Academy of Sciences, which was much closer integrated with the government, provided with more state funding as an organization, and where the title of ''Academician'' implied in a lot more rights when it came ...

Organic Chemistry
Organic chemistry is a subdiscipline within chemistry involving the science, scientific study of the structure, properties, and reactions of organic compounds and organic matter, organic materials, i.e., matter in its various forms that contain carbon atoms.Clayden, J.; Greeves, N. and Warren, S. (2012) ''Organic Chemistry''. Oxford University Press. pp. 1–15. . Study of structure determines their structural formula. Study of properties includes Physical property, physical and Chemical property, chemical properties, and evaluation of Reactivity (chemistry), chemical reactivity to understand their behavior. The study of organic reactions includes the organic synthesis, chemical synthesis of natural products, drugs, and polymers, and study of individual organic molecules in the laboratory and via theoretical (in silico) study. The range of chemicals studied chemistry includes hydrocarbons (compounds containing only carbon and hydrogen) as well as compounds based on carbon, but a ...

Petrochemical
Petrochemicals (sometimes abbreviated as petchems) are the chemical products obtained from petroleum by refining. Some chemical compounds made from petroleum are also obtained from other fossil fuels, such as coal or natural gas, or renewable sources such as maize, palm fruit or sugar cane. The two most common petrochemical classes are olefins (including ethylene and propylene) and aromatics (including benzene, toluene and xylene isomers). Oil refineries produce olefins and aromatics by fluid catalytic cracking of petroleum fractions. Chemical plants produce olefins by steam cracking of natural gas liquids like ethane and propane. Aromatics are produced by catalytic reforming of naphtha. Olefins and aromatics are the building-blocks for a wide range of materials such as solvents, detergents, and adhesives. Olefins are the basis for polymers and oligomers used in plastics, resins, fibers, elastomers, lubricants, and gels. Global ethylene production was 190 milli ...

War Production Board
The War Production Board (WPB) was an agency of the United States government that supervised war production during World War II. President Franklin D. Roosevelt established it in January 1942, with Executive Order 9024. The WPB replaced the Supply Priorities and Allocations Board and the Office of Production Management. The WPB directed conversion of companies engaged in activities relevant to war from peacetime work to war needs, allocated scarce materials, established priorities in the distribution of materials and services, and prohibited nonessential production. It rationed such commodities as gasoline, heating oil, metals, rubber, paper, and plastics. It was dissolved almost exactly two months after the defeat of Japan in 1945 and was replaced by the Civilian Production Administration in late 1945. In 1942–1945, WPB supervised the production of $183 billion (equivalent to $ in ) worth of weapons and supplies, about 40 percent of the world output of munitions ...

Rubber
Rubber, also called India rubber, latex, Amazonian rubber, ''caucho'', or ''caoutchouc'', as initially produced, consists of polymers of the organic compound isoprene, with minor impurities of other organic compounds. Types of polyisoprene that are used as natural rubbers are classified as elastomers. Currently, rubber is harvested mainly in the form of the latex from the Hevea brasiliensis, Pará rubber tree (''Hevea brasiliensis'') or others. The latex is a sticky, milky and white colloid drawn off by making incisions in the bark and collecting the fluid in vessels in a process called "tapping". Manufacturers refine this latex into the rubber that is ready for commercial processing. Natural rubber is used extensively in many applications and products, either alone or in combination with other materials. In most of its useful forms, it has a large stretch ratio and high resilience and also is buoyant and water-proof. Industrial demand for rubber-like materials began to out ...
