Geoffrey Eglinton
Geoffrey Eglinton, FRS (1 November 1927 – 11 March 2016) was a British chemist and emeritus professor and senior research fellow in earth sciences at the University of Bristol. Education Eglinton was educated at Sale Grammar School and the University of Manchester where he was awarded Bachelor of Science, Doctor of Philosophy and Doctor of Science degrees. Research and career Eglinton's insights into the geological fate of organic compounds have made him an internationally respected biogeochemist. In addition to the significance of his research on molecular biomarkers (‘chemical fossils’), he was responsible for developing numerous experimental techniques that remain in widespread use. One of the first researchers to illustrate the potential of coupled gas chromatography–mass spectrometry in organic geochemistry, Eglinton also pioneered the use of infrared spectroscopy to characterise both inter- and intra-molecular hydrogen bonding. These innovative techniques impro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cardiff
Cardiff (; cy, Caerdydd ) is the capital city, capital and List of urban areas in the United Kingdom, largest city of Wales. It forms a Principal areas of Wales, principal area, officially known as the City and County of Cardiff ( cy, Dinas a Sir Caerdydd, links=no), and the city is the List of cities in the United Kingdom, eleventh-largest in the United Kingdom. Located in the South East Wales, south-east of Wales and in the Cardiff Capital Region, Cardiff is the county town of the Historic counties of Wales, historic county of Glamorgan and in 1974–1996 of South Glamorgan. It belongs to the Eurocities network of the largest European cities. A small town until the early 19th century, its prominence as a port for coal when mining began in the region helped its expansion. In 1905, it was ranked as a city and in 1955 proclaimed capital of Wales. Cardiff Urban Area, Cardiff Built-up Area covers a larger area outside the county boundary, including the towns of Dinas Powys and Pena ...

Gas Chromatography–mass Spectrometry
Gas chromatography–mass spectrometry (GC-MS) is an analytical method that combines the features of gas-chromatography and mass spectrometry to identify different substances within a test sample. Applications of GC-MS include drug detection, fire investigation, environmental analysis, explosives investigation, and identification of unknown samples, including that of material samples obtained from planet Mars during probe missions as early as the 1970s. GC-MS can also be used in airport security to detect substances in luggage or on human beings. Additionally, it can identify trace elements in materials that were previously thought to have disintegrated beyond identification. Like liquid chromatography–mass spectrometry, it allows analysis and detection even of tiny amounts of a substance. GC-MS has been regarded as a "gold standard" for forensic substance identification because it is used to perform a 100% specific test, which positively identifies the presence of a particula ...

Eglinton Reaction
The Glaser coupling is a type of coupling reaction. It is by far the oldest acetylenic coupling and is based on cuprous salts like copper(I) chloride or copper(I) bromide and an additional oxidant like oxygen. The base in its original scope is ammonia. The solvent is water or an alcohol. The reaction was first reported by in 1869. He suggested the following process for his way to diphenylbutadiyne: :CuCl + PhC2H + NH3 → PhC2Cu + NH4Cl :2PhC2Cu + O → PhC2C2Ph + Cu2O Modifications Eglinton reaction In the related Eglinton reaction two terminal alkynes are coupled by a copper(II) salt such as cupric acetate. :2R-\!\!-H -> ce\ce] R-\!\!-\!\!-R The oxidative coupling of alkynes has been used to synthesize a number of fungal antibiotics. The stoichiometry is represented by this highly simplified scheme: : Such reactions proceed via metal-alkyne complex, copper(I)-alkyne complexes. This methodology was used in the synthesis of cyclooctadecanonaene. Another example is the synt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dan David Prize
The Dan David Prize is a major international award that recognizes and supports outstanding contributions to the study of history and other disciplines that shed light on the human past. It awards nine prizes of $300,000 each year to outstanding early- and mid-career scholars and practitioners in the historical disciplines. The Prize has an annual purse of $3 million, making it the largest history award in the world, with the remaining $300,000 funding an international postdoctoral fellowship program at Tel Aviv University, where the Prize is headquartered. The Prize is endowed by the Dan David Foundation. Until 2021 the Prize awarded 3 annual prizes of $1 million for innovative and interdisciplinary research in three time dimensions: Past, Present and Future. Prize laureates donated 10 percent of their prize money to doctoral scholarships for outstanding Ph.D. students and postdoctoral scholarships in their own field from around the world.
