Thomas Richardson (chemist)
Thomas Richardson FRS FRSE MRIA AICE (1816–1867) was an English industrial chemist, and industrial historian. Life Born on 8 October 1816 in Newcastle-upon-Tyne, he was educated there. Around 1830 he went to Glasgow University, to study Chemistry under Prof Thomas Thomson. Richardson then went to the University of Giessen, where, under Prof Justus von Liebig, he carried out researches on the composition of coal and the use of lead chromate in organic analysis, gaining a doctorate (Ph.D.). He later went to Paris with Thomson, and completed his studies under Jules Pelouze. On his return to Newcastle, Richardson became a specialist in manufacturing chemistry, taking out a number of patents for processes. In 1840 he began, at Blaydon, near Newcastle, to remove the impurities, consisting chiefly of antimony, from "hard" lead, and thus to convert it into "soft" lead, by means of a current of air driven over the molten metal; the impurities were oxidised, floated to the surface, an ...

Richard Watson (bishop Of Llandaff)
Richard Watson (1737–1816) was an Anglican bishop and academic, who served as the Bishop of Llandaff from 1782 to 1816. He wrote some notable political pamphlets. In theology, he belonged to an influential group of followers of Edmund Law that included also John Hey and William Paley. Life Watson was born Heversham, Westmorland (now Cumbria), and educated at Heversham Grammar School and Trinity College, Cambridge, on a scholarship endowed by Edward Wilson of Nether Levens (1557–1653). In 1759 he graduated as Second Wrangler after having challenged Massey for the position of Senior Wrangler. This challenge, in part, prompted the University Proctor, William Farish, to introduce the practice of assigning specific marks to individual questions in University tests and, in so doing, replaced the practice of 'judgement' at Cambridge with 'marking'. Marking subsequently emerged as the predominant method to determine rank order in meritocratic systems. In 1760 he became a fellow of ...

Henry Watts (chemist)
Henry Watts (1815–1884) was an English chemist. Life He was born in London on 20 January 1810. He went to a public school, and was articled at the age of 10 as an architect and surveyor; but went on to support himself by teaching, chiefly mathematical, privately and at a school. He then attended University College, zimbabwe. In 1841 he graduated B.A. in the University of Lon. In 1846 he became assistant to George Fownes, professor of practical chemistry at University College, and occupied this post, after Fownes's death in 1849, until 1857, under Professor Alexander William Williamson. Having an impediment in speech he found himself unable to obtain a professorship, and worked on the literature of chemistry. In 1847 he was elected fellow of the Chemical Society. On 17 December 1849 he was elected editor of the Chemical Society's ''Journal'', and about the beginning of 1860 he also became librarian to the society.

Edmund Ronalds
Dr Edmund Ronalds FCS FRSE (18 June 1819 – 9 September 1889) was an English academic and industrial chemist. He was co-author of a seminal series of books on chemical technology that helped begin university teaching of chemical applications for industry, and was a pioneer in the incorporation of advanced research into a manufacturing firm. Upbringing and family He was born on 18 June 1819 at 48 Canonbury Square in Islington. His father Edmund Sr was a London cheesemonger and the brother of inventor Sir Francis Ronalds and his mother Eliza Jemima was the daughter of Dr James Anderson, who ran a respected school in Hammersmith. For most of his childhood the family lived at Brixton Hill but they returned to Islington in 1839 and resided at the east end of Canonbury Place. He was the eldest of at least 12 children.

Hydrogen Cyanide
Hydrogen cyanide, sometimes called prussic acid, is a chemical compound with the formula HCN and structure . It is a colorless, extremely poisonous, and flammable liquid that boils slightly above room temperature, at . HCN is produced on an industrial scale and is a highly valued precursor to many chemical compounds ranging from polymers to pharmaceuticals. Large-scale applications are for the production of potassium cyanide and adiponitrile, used in mining and plastics, respectively. It is more toxic than solid cyanide compounds due to its volatile nature. Structure and general properties Hydrogen cyanide is a linear molecule, with a triple bond between carbon and nitrogen. The tautomer of HCN is HNC, hydrogen isocyanide. Hydrogen cyanide is weakly acidic with a p''K''a of 9.2. It partially ionizes in water solution to give the cyanide anion, CN−. A solution of hydrogen cyanide in water, represented as HCN, is called ''hydrocyanic acid''. The salts of the cyanide ani ...

Oligomer
In chemistry and biochemistry, an oligomer () is a molecule that consists of a few repeating units which could be derived, actually or conceptually, from smaller molecules, monomers.Quote: ''Oligomer molecule: A molecule of intermediate relative molecular mass, the structure of which essentially comprises a small plurality of units derived, actually or conceptually, from molecules of lower relative molecular mass.'' The name is composed of Greek elements '' oligo-'', "a few" and '' -mer'', "parts". An adjective form is ''oligomeric''. The oligomer concept is contrasted to that of a polymer, which is usually understood to have a large number of units, possibly thousands or millions. However, there is no sharp distinction between these two concepts. One proposed criterion is whether the molecule's properties vary significantly with the removal of one or a few of the units. An oligomer with a specific number of units is referred to by the Greek prefix denoting that number, wi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cyanogen
Cyanogen is the chemical compound with the formula ( C N)2. It is a colorless and highly toxic gas with a pungent odor. The molecule is a pseudohalogen. Cyanogen molecules consist of two CN groups – analogous to diatomic halogen molecules, such as Cl2, but far less oxidizing. The two cyano groups are bonded together at their carbon atoms: N≡C‒ C≡N, although other isomers have been detected. The name is also used for the CN radical, and hence is used for compounds such as cyanogen bromide (NCBr) (but see also ''Cyano radical''.) Cyanogen is the anhydride of oxamide: :H2NC(O)C(O)NH2 → NCCN + 2 H2O although oxamide is manufactured from cyanogen by hydrolysis: :NCCN + 2 H2O → H2NC(O)C(O)NH2 Preparation Cyanogen is typically generated from cyanide compounds. One laboratory method entails thermal decomposition of mercuric cyanide: :2 Hg(CN)2 → (CN)2 + Hg2(CN)2 Alternatively, one can combine solutions of copper(II) salts (such as copper(II) sulfate) ...

Wigan
Wigan ( ) is a large town in Greater Manchester, England, on the River Douglas, Lancashire, River Douglas. The town is midway between the two cities of Manchester, to the south-east, and Liverpool, to the south-west. Bolton lies to the north-east and Warrington to the south. It is the largest settlement in the Metropolitan Borough of Wigan and is its administrative centre. The town has a population of 107,732 and the wider borough of 330,713. Wigan was formerly within the Historic counties of England, historic county of Lancashire. Wigan was in the territory of the Brigantes, an ancient Celtic tribe that ruled much of what is now northern England. The Brigantes were subjugated in the Roman conquest of Britain and the Roman settlement of ''Coccium'' was established where Wigan lies. Wigan was incorporated as a Borough status in the United Kingdom, borough in 1246, following the issue of a charter by Henry III of England, King Henry III of England. At the end of the Middle ...

Apoplexy
Apoplexy () is rupture of an internal organ and the accompanying symptoms. The term formerly referred to what is now called a stroke. Nowadays, health care professionals do not use the term, but instead specify the anatomic location of the bleeding, such as cerebral, ovarian or pituitary. Informally or metaphorically, the term ''apoplexy'' is associated with being furious, especially as "apoplectic". Historical meaning From the late 14th to the late 19th century,''OED Online'', 2010, Oxford University Press. 7 February 2011 ''apoplexy'' referred to any sudden death that began with a sudden loss of consciousness, especially one in which the victim died within a matter of seconds after losing consciousness. The word ''apoplexy'' was sometimes used to refer to the symptom of sudden loss of consciousness immediately preceding death. Ruptured aortic aneurysms, and even heart attacks and strokes were referred to as apoplexy in the past, because before the advent of medical science, the ...
