John H. Beynon
John H. Beynon FRS (29 December 1923 – 24 August 2015) was a Welsh chemist and physicist known for his work in mass spectrometry. Education and military service Beynon was born in the Welsh coal-mining town of Ystalyfera and was the older of two brothers. He went on to attend the University of Wales at Swansea (now Swansea University) in the early 1940s at the start of World War II. He received a B.S. in physics in 1943. He did not attend graduate school, instead deciding to join the Fighting Vehicles Research Establishment where he served between 1943 and 1947 developing tank fire-control systems. Career in industry Between the year 1947 and 1969, Beynon was Manager of Physics and Physical, Polymer and Analytical Chemistry at Imperial Chemical Industries. Between 1947 and 1950, Beynon constructed what was to become the first mass spectrometer designed to study organic compounds unrelated to petroleum. He subsequently collaborated with Metropolitan-Vickers to produce th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ystalyfera
Ystalyfera is a former industrial village and community in the upper Swansea Valley, on the River Tawe, about northeast of Swansea. It is an electoral ward and a community in the unitary authority of Neath Port Talbot, Wales, comprising a resident population of just over 3,000 people, approximately 60% of whom speak Welsh. National Cycle Route 43 passes through the village. History The history of Ystalyfera begins with a small farming family who shared the land. This is reflected in the village's name, composed from the Welsh words, ynys (meaning island), tal (meaning tall) and berran (a composite of ber and rhan, indicating a land-share – a short piece of shared land, probably between agricultural labourers). The history of the name can be seen as it evolved through the ages: - *1582 Ynys Tal y Feran *1604 Tir Ynystalferran *1797 Stalyfera Issa, Ycha, Genol *1831 Ystalyfera Ystalyfera grew as a village with the advent of coal mining and iron working which, together wit ...

Metropolitan-Vickers
Metropolitan-Vickers, Metrovick, or Metrovicks, was a British heavy electrical engineering company of the early-to-mid 20th century formerly known as British Westinghouse. Highly diversified, it was particularly well known for its industrial electrical equipment such as generators, steam turbines, switchgear, transformers, electronics and railway traction equipment. Metrovick holds a place in history as the builders of the first commercial transistor computer, the Metrovick 950, and the first British axial-flow jet engine, the Metropolitan-Vickers F.2. Its factory in Trafford Park, Manchester, was for most of the 20th century one of the biggest and most important heavy engineering facilities in Britain and the world. History Metrovick started as a way to separate the existing British Westinghouse Electrical and Manufacturing Company factories from United States control, which had proven to be a hindrance to gaining government contracts during the First World War. In 1917 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Mass Spectrometrists
Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a physical body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses. An object on the Moon would weigh l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Unimolecular Ion Decomposition
Unimolecular ion decomposition is the fragmentation of a gas phase ion in a reaction with a molecularity of one. Ions with sufficient internal energy may fragment in a mass spectrometer, which in some cases may degrade the mass spectrometer performance, but in other cases, such as tandem mass spectrometry, the fragmentation can reveal information about the structure of the ion. Wahrhaftig diagram A Wahrhaftig diagram (named after Austin L. Wahrhaftig) illustrates the relative contributions in unimolecular ion decomposition of direct fragmentation and fragmentation following rearrangement. The x-axis of the diagram represents the internal energy of the ion. The lower part of the diagram shows the logarithm of the rate constant ''k'' for unimolecular dissociation whereas the upper portion of the diagram indicates the probability of forming a particular product ion. The green trace in the lower part of the diagram indicates the rate of the rearrangement reaction given by :ABCD+ -> + ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mass-analyzed Ion-kinetic-energy Spectrometry
Mass-analyzed ion kinetic-energy spectrometry (MIKES) is a mass spectrometry technique by which mass spectra are obtained from a sector instrument that incorporates at least one magnetic sector plus one electric sector in reverse geometry (the beam first enters the magnetic sector). The accelerating voltage ''V'', and the magnetic field ''B'', are set to select the precursor ions of a particular ''m/z''. The precursor ions then dissociate or react in an electric field-free region between the two sectors. The ratio of the kinetic energy to charge of the product ions are analyzed by scanning the electric sector field ''E''. The width of the product ion spectrum peaks is related to the kinetic energy release distribution for the dissociation process. History MIKES was developed at Purdue University in 1973 by Beynon, Cooks, J. W. Amy, W. E. Baitinger, and T. Y. Ridley."MIKES: History and Significance .ASMS, Web. .

Jozef Stefan
Josef Stefan ( sl, Jožef Štefan; 24 March 1835 – 7 January 1893) was an ethnic Carinthian Slovene physicist, mathematician, and poet of the Austrian Empire. Life and work Stefan was born in an outskirt village of St. Peter (Slovene: ; today a district of Klagenfurt) in the Austrian Empire (now in Austria) to father Aleš (Aleksander) Stefan, born in 1805, and mother Marija Startinik, born 1815. His parents, both ethnic Slovenes, married when Josef was eleven. The Stefans were a modest family. His father was a milling assistant and his mother served as a maidservant. Stefan's mother died in 1863 and his father in 1872. Josef was their only child. Stefan attended elementary school in Klagenfurt, where he showed his talent. They recommended to him to continue his schooling, so in 1845, he went to . As a thirteen-year-old boy, he experienced the revolutionary year of 1848, which inspired him to be sympathetic toward Slovene literary production. After having graduated top o ...
