Bill Price (physicist)
Professor William Charles Price FRS (1 April 1909 – 10 March 1993) was a British physicist (spectroscopy). Brought up in Swansea, he spent his career at the universities of Cambridge and London. His work was important for identifying the hydrogen bond structure of DNA base pairs. Early life and studies William Charles Price was born on 1 April 1909. He went to the Bishop Gore School in Swansea, where his contemporaries included the young poet Dylan Thomas, whose father taught English at the school. He failed to get a state scholarship to Oxford in 1927. He gained a BSc in Physics from Swansea University in 1930. Price then spent three years as a Fellow at Johns Hopkins University in Baltimore, Maryland, USA. He was appointed to the University of Cambridge on a 1851 Research Fellowship in 1935, at the university's Physical Chemical Laboratory - working with Martin Lowry until 1936, then with Ronald George Wreyford Norrish. In 1937 he became university demonstrator; and from ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hydrogen Bond
In chemistry, a hydrogen bond (or H-bond) is a primarily electrostatic force of attraction between a hydrogen (H) atom which is covalently bound to a more electronegative "donor" atom or group (Dn), and another electronegative atom bearing a lone pair of electrons—the hydrogen bond acceptor (Ac). Such an interacting system is generally denoted , where the solid line denotes a polar covalent bond, and the dotted or dashed line indicates the hydrogen bond. The most frequent donor and acceptor atoms are the second-row elements nitrogen (N), oxygen (O), and fluorine (F). Hydrogen bonds can be intermolecular (occurring between separate molecules) or intramolecular (occurring among parts of the same molecule). The energy of a hydrogen bond depends on the geometry, the environment, and the nature of the specific donor and acceptor atoms and can vary between 1 and 40 kcal/mol. This makes them somewhat stronger than a van der Waals interaction, and weaker than fully covalent ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Meldola Medal And Prize
The Meldola Medal and Prize was awarded annually from 1921 to 1979 by the Chemical Society and from 1980 to 2008 by the Royal Society of Chemistry to a British chemist who was under 32 years of age for promising original investigations in chemistry (which had been published). It commemorated Raphael Meldola, President of the Maccabaeans and the Institute of Chemistry. The prize was the sum of £500 and a bronze medal. The prize was modified in 2008 and joined the Edward Harrison Memorial Prize to become the Harrison-Meldola Memorial Prizes.

Infrared Spectroscopy
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used to characterize new materials or identify and verify known and unknown samples. The method or technique of infrared spectroscopy is conducted with an instrument called an infrared spectrometer (or spectrophotometer) which produces an infrared spectrum. An IR spectrum can be visualized in a graph of infrared light absorbance (or transmittance) on the vertical axis vs. frequency, wavenumber or wavelength on the horizontal axis. Typical units of wavenumber used in IR spectra are reciprocal centimeters, with the symbol cm−1. Units of IR wavelength are commonly given in micrometers (formerly called "microns"), symbol μm, which are related to the wavenumber in a reciprocal way. A com ...

Rydberg Formula
In atomic physics, the Rydberg formula calculates the wavelengths of a spectral line in many chemical elements. The formula was primarily presented as a generalization of the Balmer series for all atomic electron transitions of hydrogen. It was first empirically stated in 1888 by the Swedish physicist Johannes Rydberg, then theoretically by Niels Bohr in 1913, who used a primitive form of quantum mechanics. The formula directly generalizes the equations used to calculate the wavelengths of the hydrogen spectral series. History In 1880, Rydberg worked on a formula describing the relation between the wavelengths in spectral lines of alkali metals. He noticed that lines came in series and he found that he could simplify his calculations using the wavenumber (the number of waves occupying the unit length, equal to 1/''λ'', the inverse of the wavelength) as his unit of measurement. He plotted the wavenumbers (''n'') of successive lines in each series against consecutive integers w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

King's College London
King's College London (informally King's or KCL) is a public research university located in London, England. King's was established by royal charter in 1829 under the patronage of King George IV and the Duke of Wellington. In 1836, King's became one of the two founding colleges of the University of London. It is one of the oldest university-level institutions in England. In the late 20th century, King's grew through a series of mergers, including with Queen Elizabeth College and Chelsea College of Science and Technology (in 1985), the Institute of Psychiatry (in 1997), the United Medical and Dental Schools of Guy's and St Thomas' Hospitals and the Florence Nightingale School of Nursing and Midwifery (in 1998). King's has five campuses: its historic Strand Campus in central London, three other Thames-side campuses (Guy's, St Thomas' and Waterloo) nearby and one in Denmark Hill in south London. It also has a presence in Shrivenham, Oxfordshire, for its professional mi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Billingham Manufacturing Plant
The Billingham Manufacturing Plant is a large chemical works based in the Borough of Stockton-on-Tees, England. In agricultural terms, it is one of the most important factories in Britain. History Brunner Mond Ammonia had first been made in Germany in 1913 by BASF at Oppau, near Ludwigshafen (the plant was destroyed in 1921 by the Oppau explosion). Ammonium compounds are used not only for fertilisers, but also explosives. Billingham-on-Tees was a small village in 1917, when its Grange Farm was chosen to be the site of a large chemical works. On 22 March 1918, the Minister of Munitions approved the site to be developed as a factory that would make ammonium nitrate. It was initially known as the Government Nitrogen Factory – it fixed atmospheric nitrogen. Brunner Mond took over the works on 22 April 1920, in an agreement with the Minister of Munitions, Andrew Weir, 1st Baron Inverforth. The site was developed (copied) from knowledge of the ammonia plant at Oppau in Germany, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Imperial Chemical Industries
Imperial Chemical Industries (ICI) was a British chemical company. It was, for much of its history, the largest manufacturer in Britain. It was formed by the merger of four leading British chemical companies in 1926. Its headquarters were at Millbank in London. ICI was a constituent of the FT 30 and later the FTSE 100 indices. ICI made general chemicals, plastics, paints, pharmaceuticals and speciality products, including food ingredients, speciality polymers, electronic materials, fragrances and flavourings. In 2008, it was acquired by AkzoNobel, which immediately sold parts of ICI to Henkel and integrated ICI's remaining operations within its existing organisation. History Development of the business (1926–1944) The company was founded in December 1926 from the merger of four companies: Brunner Mond, Nobel Explosives, the United Alkali Company, and British Dyestuffs Corporation. It established its head office at Millbank in London in 1928. Competing with DuPont a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
