Lorin B. Sebrell
Lorin Beryl Sebrell (19 November 1894 – 5 August 1984) was an American scientist at the Goodyear Tire and Rubber Co. noted for identifying mercaptobenzothiazole as a vulcanization accelerator. In 1942, Sebrell received the Charles Goodyear Medal. Biography Sebrell was born on 19 November 1894 in Alliance, Ohio. In 1918, he married Ruth Ellen Tullis. He received his B.S. in chemistry from Mount Union College. After completing his M.S., he served in the Chemical Warfare Service during World War I. He obtained his Ph.D. in 1922 from Ohio State University after starting work at Goodyear in 1919. In 1920 Sebrell isolated mercaptobenzothiazole, an important rubber vulcanization accelerator from various reactions. Although well known since the 1880s, Sebrell's insight was that it is generated in situ during the zinc-catalyzed vulcanization of rubber. He devised ways of producing mercaptothiazole on a commercial scale. The new accelerator was named Captax. Captax, which was vital ...

Director Of Research And Development
Research and development (R&D or R+D), known in Europe as research and technological development (RTD), is the set of innovative activities undertaken by corporations or governments in developing new services or products, and improving existing ones. Research and development constitutes the first stage of development of a potential new service or the production process. R&D activities differ from institution to institution, with two primary models of an R&D department either staffed by engineers and tasked with directly developing new products, or staffed with industrial scientists and tasked with applied research in scientific or technological fields, which may facilitate future product development. R&D differs from the vast majority of corporate activities in that it is not intended to yield immediate profit, and generally carries greater risk and an uncertain return on investment. However R&D is crucial for acquiring larger shares of the market through the marketisation o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Polymer Scientists And Engineers
A polymer (; Greek ''wikt:poly-, poly-'', "many" + ''wikt:-mer, -mer'', "part") is a Chemical substance, substance or material consisting of very large molecules called macromolecules, composed of many Repeat unit, repeating subunits. Due to their broad spectrum of properties, both synthetic and natural polymers play essential and ubiquitous roles in everyday life. Polymers range from familiar synthetic plastics such as polystyrene to natural biopolymers such as DNA and proteins that are fundamental to biological structure and function. Polymers, both natural and synthetic, are created via polymerization of many small molecules, known as monomers. Their consequently large molecular mass, relative to small molecule compound (chemistry), compounds, produces unique physical property, physical properties including toughness, high rubber elasticity, elasticity, viscoelasticity, and a tendency to form glass, amorphous and crystallization of polymers, semicrystalline structures rather ...

The News Journal
''The News Journal'' is the main newspaper for Wilmington, Delaware, and the surrounding area. It is headquartered in unincorporated New Castle County, Delaware, near New Castle, and is owned by Gannett. History The ancestry of the News Journal reflects the mergers of several newspapers. It is dated to Oct. 1, 1866 when Howard M. Jenkins and Wilmer Atkinson started the afternoon publication ''Daily Commercial''. In 1877, that paper was absorbed into a rival, the ''Every Evening'', founded by Georgetown native William T. Croasdale. The ''Evening Journal'', later owned by the Du Pont family, was founded in 1888 as a competitor to the Every Evening. The two papers merged in 1933. Another predecessor to the News Journal was the ''Morning Herald'', founded in 1876 by Philadelphia lawyer John O'Byrne. It later became the Daily Morning News, bought by Alfred I. Du Pont in 1911. For most of the 20th century, the Du Pont family owned these two Delaware newspapers, ''The Morning News' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

International Latex Corporation
Playtex is an American brand name for undergarments, baby products, gloves, feminine hygiene products, and sunscreen. The brand began in 1947 when International Latex Corporation (ILC) created a division named Playtex to produce and sell latex products. Playtex was the first to advertise undergarments on national television in 1955, written by Howard Shavelson at Olgilvie and Mather, and the first to show a woman wearing only a bra from the waist-up in a commercial in 1977. They developed space suits for the Apollo program. Playtex-branded tampons were introduced in the 1960s and became the primary competition to incumbent Tampax. Playtex invented the plastic tampon applicator in 1973. It was one of the tampon manufacturers that were sued for aggressively advertising over-absorbent tampons that led to toxic shock syndrome. Playtex was acquired by Esmark in 1975, and then by Beatrice Foods in 1985. A year later, it was acquired for $1.25 billion, and its cosmetics brands were so ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mercaptobenzothiazole
2-Mercaptobenzothiazole is an organosulfur compound with the formula . It is used in the sulfur vulcanization of rubber. Structure The molecule is planar with a C=S double bond, so the name ''mercapto''benzothiazole is a misnomer. It is not a thiol, but instead is a thioamide, in the solid state, gas-phase, and in solution. A more appropriate name is benzothiazoline-2-thione. Solution measurements by NMR spectroscopy reveal no evidence for the thiol tautomer. Theory also indicates that the thiol tautomer is about 39 kJ/mol higher in energy than the thioamide. Synthesis and reactions The compound has been produced by many methods. The industrial route entails the high temperature reaction of aniline and carbon disulfide in the presence of sulfur, which proceeds by this idealized equation: : The traditional route is the reaction of 2-aminothiophenol and carbon disulfide: : This method was developed by the discoverer of the compound, A. W. Hoffmann. Other routes developed by H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ohio State University
The Ohio State University, commonly called Ohio State or OSU, is a public land-grant research university in Columbus, Ohio. A member of the University System of Ohio, it has been ranked by major institutional rankings among the best public universities in the United States. Founded in 1870 as the state's land-grant university and the ninth university in Ohio with the Morrill Act of 1862, Ohio State was originally known as the Ohio Agricultural and Mechanical College and focused on various agricultural and mechanical disciplines, but it developed into a comprehensive university under the direction of then-Governor and later U.S. president Rutherford B. Hayes, and in 1878, the Ohio General Assembly passed a law changing the name to "the Ohio State University" and broadening the scope of the university. Admission standards tightened and became greatly more selective throughout the 2000s and 2010s. Ohio State's political science department and faculty have greatly contri ...

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
