Cyril N. Hinshelwood
Sir Cyril Norman Hinshelwood (19 June 1897 – 9 October 1967) was a British physical chemist and expert in chemical kinetics. His work in reaction mechanisms earned the 1956 Nobel Prize in chemistry. Education Born in London, his parents were Norman Macmillan Hinshelwood, a chartered accountant, and Ethel Frances née Smith. He was educated first in Canada, returning in 1905 on the death of his father to a small flat in Chelsea where he lived for the rest of his life. He then studied at Westminster City School and Balliol College, Oxford. Career During the First World War, Hinshelwood was a chemist in an explosives factory. He was a tutor at Trinity College, Oxford, from 1921 to 1937 and was Dr Lee's Professor of Chemistry at the University of Oxford from 1937. He served on several advisory councils on scientific matters to the British Government. His early studies of molecular kinetics led to the publication of ''Thermodynamics for Students of Chemistry'' and ''The Kinet ...

Physical Chemistry
Physical chemistry is the study of macroscopic and microscopic phenomena in chemical systems in terms of the principles, practices, and concepts of physics such as motion, energy, force, time, thermodynamics, quantum chemistry, statistical mechanics, analytical dynamics and chemical equilibria. Physical chemistry, in contrast to chemical physics, is predominantly (but not always) a supra-molecular science, as the majority of the principles on which it was founded relate to the bulk rather than the molecular or atomic structure alone (for example, chemical equilibrium and colloids). Some of the relationships that physical chemistry strives to understand include the effects of: # Intermolecular forces that act upon the physical properties of materials ( plasticity, tensile strength, surface tension in liquids). # Reaction kinetics on the rate of a reaction. # The identity of ions and the electrical conductivity of materials. # Surface science and electrochemistry of cell m ...

Chelsea, London
Chelsea is an area in West London, England, due south-west of Kilometre zero#Great Britain, Charing Cross by approximately . It lies on the north bank of the River Thames and for postal purposes is part of the SW postcode area, south-western postal area. Chelsea historically formed a manor and parish in the Ossulstone hundred of Middlesex, which became the Metropolitan Borough of Chelsea in 1900. It merged with the Metropolitan Borough of Kensington, forming the Royal Borough of Kensington and Chelsea upon the creation of Greater London in 1965. The exclusivity of Chelsea as a result of its high property prices historically resulted in the coining of the term "Sloane Ranger" in the 1970s to describe some of its residents, and some of those of nearby areas. Chelsea is home to one of the largest communities of Americans living outside the United States, with 6.53% of Chelsea residents having been born in the U.S. History Early history The word ''Chelsea'' (also formerly ' ...

Chemistry
Chemistry is the scientific study of the properties and behavior of matter. It is a physical science within the natural sciences that studies the chemical elements that make up matter and chemical compound, compounds made of atoms, molecules and ions: their composition, structure, properties, behavior and the changes they undergo during chemical reaction, reactions with other chemical substance, substances. Chemistry also addresses the nature of chemical bonds in chemical compounds. In the scope of its subject, chemistry occupies an intermediate position between physics and biology. It is sometimes called the central science because it provides a foundation for understanding both Basic research, basic and Applied science, applied scientific disciplines at a fundamental level. For example, chemistry explains aspects of plant growth (botany), the formation of igneous rocks (geology), how atmospheric ozone is formed and how environmental pollutants are degraded (ecology), the prop ...

Nobel Prize
The Nobel Prizes ( ; ; ) are awards administered by the Nobel Foundation and granted in accordance with the principle of "for the greatest benefit to humankind". The prizes were first awarded in 1901, marking the fifth anniversary of Alfred Nobel, Alfred Nobel's death. The original Nobel Prizes covered five fields: Nobel Prize in Physics, physics, Nobel Prize in Chemistry, chemistry, Nobel Prize in Physiology or Medicine, physiology or medicine, Nobel Prize in Literature, literature, and Nobel Peace Prize, peace, specified in Nobel's will. A sixth prize, the Nobel Memorial Prize in Economic Sciences, Prize in Economic Sciences, was established in 1968 by Sveriges Riksbank (Sweden's central bank) in memory of Alfred Nobel. The Nobel Prizes are widely regarded as the most prestigious awards available in their respective fields.Nobel Prize#Shalev69, Shalev, p. 8.

Chemical Kinetics
Chemical kinetics, also known as reaction kinetics, is the branch of physical chemistry that is concerned with understanding the rates of chemical reactions. It is different from chemical thermodynamics, which deals with the direction in which a reaction occurs but in itself tells nothing about its rate. Chemical kinetics includes investigations of how experimental conditions influence the speed of a chemical reaction and yield information about the reaction's mechanism and transition states, as well as the construction of mathematical models that also can describe the characteristics of a chemical reaction. History The pioneering work of chemical kinetics was done by German chemist Ludwig Wilhelmy in 1850. He experimentally studied the rate of inversion of sucrose and he used integrated rate law for the determination of the reaction kinetics of this reaction. His work was noticed 34 years later by Wilhelm Ostwald. In 1864, Peter Waage and Cato Guldberg published the law ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Dalton Medal
The Manchester Literary and Philosophical Society, popularly known as the Lit. & Phil., is one of the oldest learned societies in the United Kingdom and second oldest provincial learned society (after the Spalding Gentlemen's Society). Prominent members have included Robert Owen, John Dalton, James Prescott Joule, Sir William Fairbairn, Tom Kilburn, Peter Mark Roget, Sir Ernest Rutherford, Alan Turing, Sir Joseph Whitworth and Dorothy Hodgkin.

The first formal meeting of the society took place on 14 March 1781. Meetings were held in a back room of Cross Street Chapel until December 1799, after which the society moved into its own premises in George Street. John Dalton conducted his experiments at these premises. The Society's original premises on George Street were destroye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Copley Medal
The Copley Medal is the most prestigious award of the Royal Society of the United Kingdom, conferred "for sustained, outstanding achievements in any field of science". The award alternates between the physical sciences or mathematics and the biological sciences. It is arguably the highest United Kingdom, British and Commonwealth of Nations, Commonwealth award for scientific achievement, and has often been included among the most distinguished international scientific awards. Given annually, the medal is the oldest Royal Society medal awarded and the oldest surviving scientific award in the world, having first been given in 1731 to Stephen Gray (scientist), Stephen Gray, for "his new Electrical Experiments: – as an encouragement to him for the readiness he has always shown in obliging the Society with his discoveries and improvements in this part of Natural Knowledge". The medal is made of silver-gilt and awarded with a £25,000 prize. It is awarded to "senior scientists" irres ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
