Friedrich Paneth
Friedrich Adolf Paneth (31 August 1887 – 17 September 1958) was an Austrian-born British chemist. Fleeing the Nazis, he escaped to Britain. He became a naturalized British citizen in 1939. After the war, Paneth returned to Germany to become director of the Max Planck Institute for Chemistry in 1953. He was considered the greatest authority of his time on volatile hydrides and also made important contributions to the study of the stratosphere. Paneth's conception of ″chemical element″ functions as the official definition adopted by the IUPAC Biography Friedrich (Fritz) Paneth was born as son of the physiologist Joseph Paneth. He and his three brothers were brought up in Protestant faith although both parents were of Jewish descent. He was educated at the Schottengymnasium a renowned school in Vienna. He studied chemistry at the University of Vienna and after working with Adolf von Baeyer at the University of Munich he received his PhD with Zdenko Hans Skraup at t ...

Joseph Paneth
Joseph Paneth (6 October 1857 – 4 January 1890) was an Austrian physiologist born in Vienna. Paneth is remembered for his description of "Paneth cells", which are cells that provide host defense against microbes in the mucosa of the small intestine. He studied at the Universities of Heidelberg and Vienna, where he worked with physiologist Ernst Wilhelm von Brücke (1819–1892). After a short stay at the University of Breslau, he returned to Vienna, where in 1886 he became a lecturer at the university. In 1883 and 1884 he worked at the zoological station at Villefranche, near Nice. He was a good friend of psychologist Sigmund Freud, who made a posthumous reference of Paneth in ''The Interpretation of Dreams''. Paneth is also remembered for his correspondence with [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

International Union Of Pure And Applied Chemistry
The International Union of Pure and Applied Chemistry (IUPAC ) is an international federation of National Adhering Organizations working for the advancement of the chemical sciences, especially by developing nomenclature and terminology. It is a member of the International Science Council (ISC). IUPAC is registered in Zürich, Switzerland, and the administrative office, known as the "IUPAC Secretariat", is in Research Triangle Park, North Carolina, United States. This administrative office is headed by IUPAC's executive director, currently Lynn Soby. IUPAC was established in 1919 as the successor of the International Congress of Applied Chemistry for the advancement of chemistry. Its members, the National Adhering Organizations, can be national chemistry societies, national academies of sciences, or other bodies representing chemists. There are fifty-four National Adhering Organizations and three Associate National Adhering Organizations. IUPAC's Inter-divisional Committee ...

Chemical Element
A chemical element is a species of atoms that have a given number of protons in their nuclei, including the pure substance consisting only of that species. Unlike chemical compounds, chemical elements cannot be broken down into simpler substances by any chemical reaction. The number of protons in the nucleus is the defining property of an element, and is referred to as its atomic number (represented by the symbol ''Z'') – all atoms with the same atomic number are atoms of the same element. Almost all of the baryonic matter of the universe is composed of chemical elements (among rare exceptions are neutron stars). When different elements undergo chemical reactions, atoms are rearranged into new compounds held together by chemical bonds. Only a minority of elements, such as silver and gold, are found uncombined as relatively pure native element minerals. Nearly all other naturally occurring elements occur in the Earth as compounds or mixtures. Air is primarily a mixture ...

Harry Julius Emeléus
Harry Julius Emeléus CBE, FRS (22 June 1903 – 2 December 1993) was a leading English inorganic chemist and a professor in the department of chemistry, Cambridge University. Early life Emeléus was born in Poplar, London on 22 June 1903, the son of Karl Henry Emeléus (1869–1948), a pharmacist who was born in Vaasa, Finland. The family moved to the Old Pharmacy in Battle, Sussex shortly after Emeléus was born. His elder brother Karl George Emeléus (1901–1989) went on to become professor of physics at the Queen's University of Belfast. Emeléus was educated at St Leonards Collegiate School, Hastings, and Hastings Grammar School followed by the Royal College of Science, Imperial College, London, graduating in 1923. He gained his PhD in 1926 and a DSc three years later.

Stratosphere
The stratosphere () is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. The stratosphere is an atmospheric layer composed of stratified temperature layers, with the warm layers of air high in the sky and the cool layers of air in the low sky, close to the planetary surface of the Earth. The increase of temperature with altitude is a result of the absorption of the Sun's ultraviolet (UV) radiation by the ozone layer. The temperature inversion is in contrast to the troposphere, near the Earth's surface, where temperature decreases with altitude. Between the troposphere and stratosphere is the tropopause border that demarcates the beginning of the temperature inversion. Near the equator, the lower edge of the stratosphere is as high as , at midlatitudes around , and at the poles about . Temperatures range from an average of near the tropopause to an average of near the mesosphere. Stratospheric temperatures also vary ...

Hydride
In chemistry, a hydride is formally the anion of hydrogen( H−). The term is applied loosely. At one extreme, all compounds containing covalently bound H atoms are called hydrides: water (H2O) is a hydride of oxygen, ammonia is a hydride of nitrogen, etc. For inorganic chemists, hydrides refer to compounds and ions in which hydrogen is covalently attached to a less electronegative element. In such cases, the H centre has nucleophilic character, which contrasts with the protic character of acids. The hydride anion is very rarely observed. Almost all of the elements form binary compounds with hydrogen, the exceptions being He, Ne, Ar, Kr, Pm, Os, Ir, Rn, Fr, and Ra. Exotic molecules such as positronium hydride have also been made. Bonds Bonds between hydrogen and the other elements range from highly to somewhat covalent. Some hydrides, e.g. boron hydrides, do not conform to classical electron-counting rules and the bonding is described in terms of multi-ce ...

Max Planck Institute For Chemistry
The Max Planck Institute for Chemistry (Otto Hahn Institute; german: Max Planck Institut für Chemie - Otto Hahn Institut) is a non-university research institute under the auspices of the Max Planck Society (German: Max-Planck-Gesellschaft) in Mainz, Germany. It was created as the Kaiser Wilhelm Institute for Chemistry in 1911 in Berlin. In 2016 research at the Max Planck Institute for Chemistry in Mainz aims at an integral understanding of chemical processes in the Earth system, particularly in the atmosphere and biosphere. Investigations address a wide range of interactions between air, water, soil, life and climate in the course of Earth history up to today's human-driven epoch, the Anthropocene. The institute consists of five scientific departments (Atmospheric Chemistry, Climate Geochemistry, Biogeochemistry, Multiphase Chemistry, and Particle Chemistry) and additional research groups. The departments are independently led by their directors. Research The institute consi ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Nazi Party
The Nazi Party, officially the National Socialist German Workers' Party (german: Nationalsozialistische Deutsche Arbeiterpartei or NSDAP), was a far-right political party in Germany active between 1920 and 1945 that created and supported the ideology of Nazism. Its precursor, the German Workers' Party (; DAP), existed from 1919 to 1920. The Nazi Party emerged from the extremist German nationalist, racist and populist paramilitary culture, which fought against the communist uprisings in post– World War I Germany. The party was created to draw workers away from communism and into nationalism. Initially, Nazi political strategy focused on anti– big business, anti- bourgeois, and anti-capitalist rhetoric. This was later downplayed to gain the support of business leaders, and in the 1930s, the party's main focus shifted to antisemitic and anti-Marxist themes. The party had little popular support until the Great Depression. Pseudoscientific racist theories were ...
