Cyril Stanley Smith
Cyril Stanley Smith (4 October 1903 – 25 August 1992) was a British metallurgist and historian of science. He is most famous for his work on the Manhattan Project where he was responsible for the production of fissionable metals. A graduate of the University of Birmingham and Massachusetts Institute of Technology (MIT), Smith worked for many years as a research metallurgist at the American Brass Company. During World War II he worked in the Chemical-Metallurgical Division of the Los Alamos Laboratory, where he purified, cast and shaped uranium-235 and plutonium, a metal hitherto available only in microgram amounts, and whose properties were largely unknown. After the war he served on the Atomic Energy Commission's influential General Advisory Committee, and the President's Science Advisory Committee. Smith founded the Institute for the Study of Metals at the University of Chicago, the first interdisciplinary academic organization devoted to the study of metals in the Unite ...

Uranium-235
Uranium-235 (235U or U-235) is an isotope of uranium making up about 0.72% of natural uranium. Unlike the predominant isotope uranium-238, it is fissile, i.e., it can sustain a nuclear chain reaction. It is the only fissile isotope that exists in nature as a primordial nuclide. Uranium-235 has a half-life of 703.8 million years. It was discovered in 1935 by Arthur Jeffrey Dempster. Its fission cross section for slow thermal neutrons is about 584.3±1 barns. For fast neutrons it is on the order of 1 barn. Most but not all neutron absorptions result in fission; a minority result in neutron capture forming uranium-236. Natural decay chain :\begin \ce \begin \ce \\ \ce \end \ce \\ \ce \begin \ce \\ \ce \end \ce \end Fission properties The fission of one atom of uranium-235 releases () inside the reactor. That corresponds to 19.54 TJ/ mol, or 83.14 TJ/kg. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Yale University
Yale University is a private research university in New Haven, Connecticut. Established in 1701 as the Collegiate School, it is the third-oldest institution of higher education in the United States and among the most prestigious in the world. It is a member of the Ivy League. Chartered by the Connecticut Colony, the Collegiate School was established in 1701 by clergy to educate Congregational ministers before moving to New Haven in 1716. Originally restricted to theology and sacred languages, the curriculum began to incorporate humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded into graduate and professional instruction, awarding the first PhD in the United States in 1861 and organizing as a university in 1887. Yale's faculty and student populations grew after 1890 with rapid expansion of the physical campus and scientific research. Yale is organized into fourteen constituent schools: the original undergraduate col ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copper Alloys
Copper alloys are metal alloys that have copper as their principal component. They have high resistance against corrosion. The best known traditional types are bronze, where tin is a significant addition, and brass, using zinc instead. Both of these are imprecise terms, having both been commonly referred to as lattens in the past. Today the term ''copper alloy'' tends to be substituted, especially by museums. Composition The similarity in external appearance of the various alloys, along with the different combinations of elements used when making each alloy, can lead to confusion when categorizing the different compositions. There are as many as 400 different copper and copper alloy compositions loosely grouped into the categories: copper, high copper alloy, brasses, bronzes, copper nickels, copper–nickel–zinc (nickel silver), leaded copper, and special alloys. The following table lists the principal alloying element for four of the more common types used in modern i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sutton Coldfield
Sutton Coldfield or the Royal Town of Sutton Coldfield, known locally as Sutton ( ), is a town and civil parish in the City of Birmingham, West Midlands, England. The town lies around 8 miles northeast of Birmingham city centre, 9 miles south of Lichfield, 7 miles southwest of Tamworth and 7 miles east of Walsall. Sutton Coldfield and its surrounding suburbs are governed under Birmingham City Council for local government purposes but the town has its own town council which governs the town and its surrounding areas by running local services and electing a mayor to the council. It is in the Historic county of Warwickshire, and in 1974 it became part of Birmingham and the West Midlands metropolitan county under the Local Government Act 1972. History Etymology The etymology of the name Sutton appears to be from "South Town". The name "Sutton Coldfield" appears to come from this time, being the "south town" (i.e. south of Tamworth and/or Lichfield) on the edge of the "col f ...

Camp Coffee
Camp Coffee is a concentrated syrup which is flavoured with coffee and chicory, first produced in 1876 by Paterson & Sons Ltd, in Glasgow. In 1974, Dennis Jenks merged his business with Paterson to form Paterson Jenks plc. In 1984, Paterson Jenks plc was bought by McCormick & Company. McCormick UK Ltd assimilated Paterson Jenks into the Schwartz brand. Camp is now produced in Paisley, Renfrewshire. Description The current ingredients of Camp Chicory & Coffee are sugar, water, chicory extract (25%) and dried coffee extract (4%). Camp is a dark brown, syrupy liquid. It has a smooth flavour of chicory and coffee but with a very sweet, predominantly chicory aftertaste. Camp is generally used by mixing with hot water or with warm milk in much the same way as cocoa, or added to cold milk and ice to make iced coffee. It is commonly found in the baking aisles of supermarkets because it is also used as an ingredient in coffee cakes and other confectionery. History Camp Coffee w ...

Samurai Sword
A is a Japanese sword characterized by a curved, single-edged blade with a circular or squared guard and long grip to accommodate two hands. Developed later than the ''tachi'', it was used by samurai in feudal Japan and worn with the edge facing upward. Since the Muromachi period, many old ''tachi'' were cut from the root and shortened, and the blade at the root was crushed and converted into ''katana''. The specific term for ''katana'' in Japan is ''uchigatana'' (打刀) and the term ''katana'' (刀) often refers to single-edged swords from around the world. Etymology and loanwords The word ''katana'' first appears in Japanese in the ''Nihon Shoki'' of 720. The term is a compound of ''kata'' ("one side, one-sided") + ''na'' ("blade"),1995, (''w:Daijisen, Daijisen'') (in Japanese), w:Tōkyō, Tōkyō: w:Shogakukan, Shogakukan, , entry available onlinhere/span> in contrast to the double-sided ''Tsurugi (sword), tsurugi''.

Grain Boundaries
In materials science, a grain boundary is the interface between two grains, or crystallites, in a polycrystalline material. Grain boundaries are two-dimensional crystallographic defect, defects in the crystal structure, and tend to decrease the electrical conductivity, electrical and thermal conductivity of the material. Most grain boundaries are preferred sites for the onset of corrosion and for the precipitation (chemistry), precipitation of new Phase (matter), phases from the solid. They are also important to many of the mechanisms of Creep (deformation), creep. On the other hand, grain boundaries disrupt the motion of dislocations through a material, so reducing crystallite size is a common way to improve mechanical strength, as described by the Hall–Petch relationship. High and low angle boundaries It is convenient to categorize grain boundaries according to the extent of misorientation between the two grains. ''Low-angle grain boundaries'' (''LAGB'') or ''subgrain boun ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
