School Of Chemistry, University Of Edinburgh
The School of Chemistry is a school of the University of Edinburgh, in Scotland. In the 2008 Research Assessment Exercise (RAE) the school was ranked sixth in the UK. History and alumni The teaching of Chemistry at Edinburgh began in 1713 when James Crawford was appointed to the 'Chair of Physik and Chymistry' (where 'physik' = natural science/art of medicine). The department has occupied many sites in its history, from a house at the top of Robertson's Close in the city centre, to purpose-built facilities in the central campus at Old College through to its current location at King's Buildings. Each move has brought with it expansions in size and status until the department occupied the position it does now, as one of the world's leading Chemistry teaching and research establishments. The department also hosts the oldest student-run Chemistry society in the world which was created in 1785 and is still active today. Today the department carries on the traditions of Chemistry at ...

Carbon Dioxide
Carbon dioxide (chemical formula ) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas. It is a trace gas in Earth's atmosphere at 421 parts per million (ppm), or about 0.04% by volume (as of May 2022), having risen from pre-industrial levels of 280 ppm. Burning fossil fuels is the primary cause of these increased CO2 concentrations and also the primary cause of climate change.IPCC (2022Summary for policy makersiClimate Change 2022: Mitigation of Climate Change.

BNCT
Neutron capture therapy (NCT) is a type of radiotherapy for treating locally invasive malignant tumors such as primary brain tumors, recurrent cancers of the head and neck region, and cutaneous and extracutaneous melanomas. It is a two-step process: ''first'', the patient is injected with a tumor-localizing drug containing the stable isotope boron-10 (B), which has a high propensity to capture low energy "thermal" neutrons. The neutron cross section of B (3,837 barns) is 1,000 times more than that of other elements, such as nitrogen, hydrogen, or oxygen, that occur in tissue. In the ''second'' step, the patient is radiated with epithermal neutrons, the sources of which in the past have been nuclear reactors and now are accelerators that produce higher energy epithermal neutrons. After losing energy as they penetrate tissue, the resultant low energy "thermal" neutrons are captured by the B atoms. The resulting decay reaction yields high-energy alpha particles that kill the cancer c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dewar Flask
A vacuum flask (also known as a Dewar flask, Dewar bottle or thermos) is an insulating storage vessel that greatly lengthens the time over which its contents remain hotter or cooler than the flask's surroundings. Invented by Sir James Dewar in 1892, the vacuum flask consists of two flasks, placed one within the other and joined at the neck. The gap between the two flasks is partially evacuated of air, creating a near-vacuum which significantly reduces heat transfer by conduction or convection. When used to hold cold liquids, this also virtually eliminates condensation on the outside of the flask. Vacuum flasks are used domestically to keep beverages hot or cold for extended periods of time, and for keeping cooked food hot. They are also used for thermal cooking. Vacuum flasks are also used for many purposes in industry. History The vacuum flask was designed and invented by Scottish scientist Sir James Dewar in 1892 as a result of his research in the field of cryogenics ...

James Dewar
Sir James Dewar (20 September 1842 – 27 March 1923) was a British chemist and physicist. He is best known for his invention of the vacuum flask, which he used in conjunction with research into the liquefaction of gases. He also studied atomic and molecular spectroscopy, working in these fields for more than 25 years. Early life James Dewar was born in Kincardine, Perthshire (now in Fife) in 1842, the youngest of six boys of Ann Dewar and Thomas Dewar, a vintner. He was educated at Kincardine Parish School and then Dollar Academy. His parents died when he was 15. He attended the University of Edinburgh where he studied chemistry under Lyon Playfair (later Baron Playfair), becoming Playfair's personal assistant. Dewar also studied under August Kekulé at Ghent. Career In 1875, Dewar was elected Jacksonian professor of natural experimental philosophy at the University of Cambridge, becoming a member of Peterhouse. He became a member of the Royal Institution and later, in 18 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Phosgene
Phosgene is the organic chemical compound with the formula COCl2. It is a toxic, colorless gas; in low concentrations, its musty odor resembles that of freshly cut hay or grass. Phosgene is a valued and important industrial building block, especially for the production of precursors of polyurethanes and polycarbonate plastics. Phosgene is extremely poisonous and was used as a chemical weapon during World War I, where it was responsible for 85,000 deaths. It was a highly potent pulmonary irritant and quickly filled enemy trenches due to it being a heavy gas. It is classified as a Schedule 3 substance under the Chemical Weapons Convention. In addition to its industrial production, small amounts occur from the breakdown and the combustion of organochlorine compounds, such as chloroform. Structure and basic properties Phosgene is a planar molecule as predicted by VSEPR theory. The C=O distance is 1.18 Å, the C−Cl distance is 1.74 Å and the Cl−C−Cl angle is 111 ...

John Davy (chemist)
John Davy FRS FRSE (24 May 1790 – 24 January 1868) was a Cornish doctor, amateur chemist, brother of the noted chemist Sir Humphry Davy, and cousin of Edmund Davy. During his career, Davy discovered phosgene, silicon tetrafluoride, and concluded that chlorine was an element. Life John Davy was born in Penzance, Cornwall, on 24 May 1790, the son of Robert Davy and his wife, Grace Millet. He assisted his older brother Humphry at the Royal Institution of Great Britain for two years before heading to Edinburgh University, where he earned his degree in medicine in 1814. In 1812, Davy discovered phosgene, a compound he also named. At the same time, he concluded that chlorine was an element. He also discovered silicon tetrafluoride Silicon tetrafluoride or tetrafluorosilane is a chemical compound with the formula Si F4. This colorless gas is notable for having a narrow liquid range: its boiling point is only 4 °C above its melting point. It was first prepared in 1771 ...

Archibald Scott Couper
Archibald Scott Couper (; 31 March 1831 – 11 March 1892) was a Scottish chemist who proposed an early theory of chemical structure and bonding. He developed the concepts of tetravalent carbon atoms linking together to form large molecules, and that the bonding order of the atoms in a molecule can be determined from chemical evidence. Life and work Couper was the only surviving son of a wealthy textile mill owner near Glasgow. He studied at the universities of Glasgow and Edinburgh and intermittently in Germany during the years 1851-54. He began the formal study of chemistry at the University of Berlin in the autumn of 1854, then in 1856 entered Charles Adolphe Wurtz's private laboratory at the Faculty of Medicine in Paris (now the University of Paris V: René Descartes). Couper published his "New Chemical Theory" in French in a condensed form on 14 June 1858, then in detailed papers simultaneously in French and English in August 1858. Couper's idea that carbon atoms ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
