Benjamin S. Garvey
Dr. Benjamin St. John Garvey (1900–1973) was a chemist at BF Goodrich who worked under Waldo L. Semon on the development of synthetic rubber, contributed to understanding of vulcanization, and developed early techniques for small scale evaluation of rubbers. In particular, he was the inventor of the Garvey die for evaluating the extrusion quality of rubber compounds. Garvey was born in Cambridge, Massachusetts. He obtained his BS in chemistry at University of Illinois 1921, taught chemistry at Episcopalian Boone University in Wuchang China for 3 years, then returned to complete his MS in 1925. He completed his PhD in organic chemistry under James Bryant Conant at Harvard and then joined BF Goodrich in 1927. In 1958, Garvey was chairman of the ACS Rubber Division. Garvey was the 1965 recipient of the Charles Goodyear Medal The Charles Goodyear Medal is the highest honor conferred by the American Chemical Society, Rubber Division.

Vulcanization
Vulcanization (British: Vulcanisation) is a range of processes for hardening rubbers. The term originally referred exclusively to the treatment of natural rubber with sulfur, which remains the most common practice. It has also grown to include the hardening of other (synthetic) rubbers via various means. Examples include silicone rubber via room temperature vulcanizing and chloroprene rubber (neoprene) using metal oxides. Vulcanization can be defined as the curing of elastomers, with the terms 'vulcanization' and 'curing' sometimes used interchangeably in this context. It works by forming cross-links between sections of polymer chain which results in increased rigidity and durability, as well as other changes in the mechanical and electrical properties of the material. Vulcanization, in common with the curing of other thermosetting polymers, is generally irreversible. The word vulcanization is derived from Vulcan, the Roman god of fire and forge.

Garvey Die
Garvey and O'Garvey are Irish surnames, derived from the Gaelic ''Ó Gairbhith'', also spelt ''Ó Gairbheith'', meaning "descendant of Gairbhith". ''Gairbhith'' itself means "rough peace". There are three distinct Ó Gairbhith septs in Ireland: * A sept of the over-kingdom of Ulaid, who were kin of the '' Mac Aonghusa''. They were located in present-day County Down, Northern Ireland. * A sept of the over-kingdom of Airgíalla, who were kin of the ''Ó hAnluain''. They at one time ruled ''Uí Bresail'', also known as ''Clann Breasail'' (Clanbrassil), located in the present-day barony of Oneilland East in County Armagh, Northern Ireland. At an early stage they were disposed of their territory by the ''Mac Cana'' sept of the neighbouring ''Clan Cana'' (Clancann). * A sept of the '' Uí Ceinnselaig'', who were at one time chiefs of ''Uí Feilmeadha Thuaidh'', located in present-day barony of Rathvilly in County Carlow, Republic of Ireland.

Boone University
Huachung University () was a Christian university in Wuhan, in China's Yangtze valley, originally called Boone University, was founded by the union of several Christian universities in 1924 and renamed Huachung in 1929. The university expanded until it was forced to retreat during the Second Sino-Japanese War, but returned to Wuhan in 1945. It was incorporated into the national university system in 1951.Peter Tze Ming Ng, Boone College The Bishop Boone Memorial School, a boarding school, opened in Wuchang in Sept., 1871, with three students. It was named after Bishop William Jones Boone, the first Episcopal Bishop of China. It became Boone College (文華書院 ''Wenhua shuyuan'') in 1905, graduated its first class in 1906, and was incorporated as a university in 1909. It comprised preparatory and college departments, a theological school, and a medical school.

Wuchang
Wuchang forms part of the urban core of and is one of 13 urban districts of the prefecture-level city of Wuhan, the capital of Hubei Province, China. It is the oldest of the three cities that merged into modern-day Wuhan, and stood on the right (southeastern) bank of the Yangtze River, opposite the mouth of the Han River. The two other cities, Hanyang and Hankou, were on the left (northwestern) bank, separated from each other by the Han River. The name "Wuchang" remains in common use for the part of urban Wuhan south of the Yangtze River. Administratively, however, it is split between several districts of the City of Wuhan. The historic center of Wuchang lies within the modern Wuchang District, which has an area of and a population of 1,003,400. Other parts of what is colloquially known as Wuchang are within Hongshan District (south and south-east) and Qingshan District (north-east). Presently, on the right bank of the Yangtze, it borders the districts of Qingshan (for a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
James Bryant Conant
James Bryant Conant (March 26, 1893 – February 11, 1978) was an American chemist, a transformative President of Harvard University, and the first U.S. Ambassador to West Germany. Conant obtained a Ph.D. in Chemistry from Harvard in 1916. During World War I he served in the U.S. Army, working on the development of poison gases, especially Lewisite. He became an assistant professor of chemistry at Harvard in 1919 and the Sheldon Emery Professor of Organic Chemistry in 1929. He researched the physical structures of natural products, particularly chlorophyll, and he was one of the first to explore the sometimes complex relationship between chemical equilibrium and the reaction rate of chemical processes. He studied the biochemistry of oxyhemoglobin providing insight into the disease methemoglobinemia, helped to explain the structure of chlorophyll, and contributed important insights that underlie modern theories of acid-base chemistry. In 1933, Conant became the Pres ... [...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 ...
