Humphrey Owen Jones
Humphrey Owen Jones (20 February 1878 – 15 August 1912) was a Welsh chemist and mountaineer. Life Jones was born at Goginan, Cardiganshire, and educated at Lewis School, Pengam, and the University College of Wales, Aberystwyth. He subsequently studied natural sciences at Clare College, Cambridge, graduating BA in 1899 and MA in 1903. In 1904 he was admitted to D. Sc. of University of London. On 1 August 1912 Jones married a colleague, Muriel Gwendolen Edwards, a keen climber and the first woman to be elected a Fellow of the University of Wales. Chemist In 1901 he obtained an official appointment of demonstrator to the Jacksonian Professor of Natural Philosophy, Sir James Dewar, which he held up to the time of his death. He was elected in due course (1902) to a Fellowship at Clare College where he subsequently became lecturer. For eleven years Jones devoted most of his time to teaching in the university laboratory and to the supervision of the science students of his college. ...

Annie Homer
Annie Homer (1882 - 1953) was a biochemist at Newnham College, Cambridge, University of Toronto and the Lister Institute. She developed improved methods for large-scale production of antitoxin sera during World War I. Personal life and education Annie Homer was born at West Bromwich, London, UK, on 3 December 1882. Her parents were Joseph and Keziah (née Skidmore) Homer. After attending King Edward VI High School for Girls in Birmingham, Homer went in 1905 to Newnham College of the University of Cambridge to study chemistry. She took the Natural Sciences Tripos in 1904 and 1905, gaining Class I, chemistry, Part II but women were not awarded degrees by this university at that time. However, she was able to obtain an MA degree from Trinity College, Dublin based on her Cambridge studies. She was awarded a DSc by Trinity College in 1913 based on research she undertook at Newnham College. She died 1 January 1953.

Goginan
Goginan is a small village in Ceredigion, about 7 miles outside Aberystwyth on the A44 between Ponterwyd and Capel Bangor. The Afon Melindwr runs through the village, and is a tributary of the Afon Rheidol. The village originally grew around farms in the area, but increased with the development of local mines. To the east of the villages lies a Grade II Listed 19th century house thought to be associated with the lead mines in the area; it is probably the Goginan mine manager's house.

Stereochemistry
Stereochemistry, a subdiscipline of chemistry, involves the study of the relative spatial arrangement of atoms that form the structure of molecules and their manipulation. The study of stereochemistry focuses on the relationships between stereoisomers, which by definition have the same molecular formula and sequence of bonded atoms (constitution), but differ in structural formula (the three-dimensional orientations of their atoms in space). For this reason, it is also known as 3D chemistry—the prefix "stereo-" means "three-dimensionality". Stereochemistry spans the entire spectrum of organic, inorganic, biological, physical and especially supramolecular chemistry. Stereochemistry includes methods for determining and describing these relationships; the effect on the physical or biological properties these relationships impart upon the molecules in question, and the manner in which these relationships influence the reactivity of the molecules in question ( dynamic stereochemis ...

Karl Blodig
Karl Blodig (16 October 1859 – 7 September 1956) was an Austrian Mountaineering, mountaineer, optician, and writer. Blodig was the first to successfully climb List of Alpine four-thousanders, all Alpine peaks of over 4000 meters, completing his final summit around 1911. He wrote about these climbs in his book ''Die Viertausender der Alpen'' (''The Four-Thousanders of the Alps''), first published in 1923. Mountaineering Life Born in Vienna, Blodig spent his early years in Graz, climbing Mount Triglav while still in his teens. At the age of twenty he climbed Monte Rosa, guided by Christian Ranggetiner, and by twenty-three he had made non-guided ascents of the Dufourspitze, Zumsteinspitze, and Weisshorn. Between 1890 and 1911 he succeeded in climbing the remaining peaks to achieve all those summits that were at that time listed as being over 4,000 m in height. These achievements included first ascents of the Mont Brouillard, Brouillard Ridge on Mont Blanc as well as the first traver ...

Lliwedd
Y Lliwedd is a mountain, connected to Snowdon in the Snowdonia National Park, North Wales. Its summit lies above sea level. The eastern flanks are steep cliffs rising above Glaslyn and Llyn Llydaw. Y Lliwedd is the most conspicuous of the peaks for those who approach Snowdon via the Miners' and Pyg tracks. Few that summit Snowdon continue over to Y Lliwedd as the challenge of Wales' highest peak is enough, leaving Y Lliwedd quiet and peaceful even when queues are forming at the summit of Snowdon. Hikers and mountaineers often pass over Y Lliwedd when walking the Snowdon Horseshoe. The noted British climber George Mallory undertook many of his early climbs here. It was also the site of considerable training activity for the 1953 British Everest Expedition. The north face of Y Lliwedd was explored in the late 19th century and in 1909 was the subject of the first British climbing guide, ''The Climbs on Lliwedd'' by J. M. A. Thomson and A. W. Andrews.

Snowdonia
Snowdonia or Eryri (), is a mountainous region in northwestern Wales and a national park of in area. It was the first to be designated of the three national parks in Wales, in 1951. Name and extent It was a commonly held belief that the name is derived from ("eagle"), and thus means "the abode/land of eagles", but recent evidence is that it means ''highlands'', and is related to the Latin (to rise) as leading Welsh scholar Sir proved. The term first appeared in a manuscript in the 9th-century , in an account of the downfall of the semi-legendary 5th-century king (Vortigern). In the Middle Ages, the title ''Prince of Wales and Lord of Snowdonia'' () was used by ; his grandfather used the title ''Prince of north Wales and Lord of Snowdonia.'' The name ''Snowdonia'' derives from '' Snowdon'', the highest mountain in the area and the highest mountain in Wales at . Before the boundaries of the national park were designated, "Snowdonia" was generally used to refer to a sm ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Royal Commission On Fuel And Engines
The British Royal Commission on Fuel and Engines was established in the United Kingdom on 31 July 1912, and its remit was " report on the means of supply and storage of Liquid Fuel in peace and war, and its application to warship engines, whether indirectly or by internal combustion." Established by Winston Churchill, First Lord of the Admiralty from 1911 to 1915, its commissioners were John Fisher, George Lambert, Thomas Boverton Redwood, Philip Watts, Henry John Oram, John Jellicoe, William Matthews, Thomas Henry Holland, Thomas Edward Thorpe, Alexander Gracie, Humphrey Owen Jones and Alfred Yarrow. Oil integration Fisher's "quest" as First Sea Lord from 1904 to early 1910 was to modernise the Navy, and, as an "oil maniac", this included changing to the use of fuel oil instead of coal for propulsion: the benefits and availability of the technology were proven, for example through "vitally important" tests involving in 1904, but the supply of oil was as yet unreliable.

Oxalate
Oxalate (IUPAC: ethanedioate) is an anion with the formula C2O42−. This dianion is colorless. It occurs naturally, including in some foods. It forms a variety of salts, for example sodium oxalate (Na2C2O4), and several esters such as dimethyl oxalate (C2O4(CH3)2). It is a conjugate base of oxalic acid. At neutral pH in aqueous solution, oxalic acid converts completely to oxalate. Relationship to oxalic acid The dissociation of protons from oxalic acid proceeds in a stepwise manner; as for other polyprotic acids, loss of a single proton results in the monovalent hydrogenoxalate anion . A salt with this anion is sometimes called an acid oxalate, monobasic oxalate, or hydrogen oxalate. The equilibrium constant ( ''K''a) for loss of the first proton is (p''K''a = 1.27). The loss of the second proton, which yields the oxalate ion, has an equilibrium constant of (p''K''a = 4.28). These values imply, in solutions with neutral pH, no oxalic acid and only trace am ...

Thiol
In organic chemistry, a thiol (; ), or thiol derivative, is any organosulfur compound of the form , where R represents an alkyl or other organic substituent. The functional group itself is referred to as either a thiol group or a sulfhydryl group, or a sulfanyl group. Thiols are the sulfur analogue of alcohols (that is, sulfur takes the place of oxygen in the hydroxyl () group of an alcohol), and the word is a blend of "''thio-''" with "alcohol". Many thiols have strong odors resembling that of garlic or rotten eggs. Thiols are used as odorants to assist in the detection of natural gas (which in pure form is odorless), and the "smell of natural gas" is due to the smell of the thiol used as the odorant. Thiols are sometimes referred to as mercaptans () or mercapto compounds, a term introduced in 1832 by William Christopher Zeise and is derived from the Latin ('capturing mercury')''Oxford American Dictionaries'' (Mac OS X Leopard). because the thiolate group () bonds very strong ...

Carbon Monosulfide
Carbon monosulfide is a chemical compound with the formula CS. This diatomic molecule is the sulfur analogue of carbon monoxide, and is unstable as a solid or a liquid, but it has been observed as a gas both in the laboratory and in the interstellar medium. The molecule resembles carbon monoxide with a triple bond between carbon and sulfur. The molecule is not intrinsically unstable, but it tends to polymerize. This tendency reflects the greater stability of C–S single bonds. Polymers with the formula (CS)''n'' have been reported. Also, CS has been observed as a ligand in some transition metal complex A coordination complex consists of a central atom or ion, which is usually metallic and is called the ''coordination centre'', and a surrounding array of bound molecules or ions, that are in turn known as ''ligands'' or complexing agents.

Carbonyl
In organic chemistry, a carbonyl group is a functional group composed of a carbon atom double-bonded to an oxygen atom: C=O. It is common to several classes of organic compounds, as part of many larger functional groups. A compound containing a carbonyl group is often referred to as a carbonyl compound. The term carbonyl can also refer to carbon monoxide as a ligand in an inorganic or organometallic complex (a metal carbonyl, e.g. nickel carbonyl). The remainder of this article concerns itself with the organic chemistry definition of carbonyl, where carbon and oxygen share a double bond. Carbonyl compounds In organic chemistry, a carbonyl group characterizes the following types of compounds: Other organic carbonyls are urea and the carbamates, the derivatives of acyl chlorides chloroformates and phosgene, carbonate esters, thioesters, lactones, lactams, hydroxamates, and isocyanates. Examples of inorganic carbonyl compounds are carbon dioxide and carbonyl sulfide. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
