Étienne Roth
Étienne Georges Alfred Roth (born 5 June 1922 in Strasbourg, died 19 March 2009 in Sèvres) was a French nuclear chemist, son of Professor George Roth and Marguerite Neymarck. From 1980-87 Roth served as the Director of Research for the separations and isotopic studies of Physical Chemistry Division (1980–87) at the Atomic Energy and Alternative Energies Commission. During his scientific career he was a visiting Scientist at US Brookhaven National Laboratory (1957-1958), Chairman of the Atomic Weights Commission (1976-1979). In his career, Roth has authored more than one hundred and fifty scientific articles and several books on applied nuclear chemistry, and has invented several methods for industrial separation of isotopes. The Prix Étienne Roth was established in his honour. [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nuclear Chemistry
Nuclear chemistry is the sub-field of chemistry dealing with radioactivity, nuclear processes, and transformations in the nuclei of atoms, such as nuclear transmutation and nuclear properties. It is the chemistry of radioactive elements such as the actinides, radium and radon together with the chemistry associated with equipment (such as nuclear reactors) which are designed to perform nuclear processes. This includes the corrosion of surfaces and the behavior under conditions of both normal and abnormal operation (such as during an accident). An important area is the behavior of objects and materials after being placed into a nuclear waste storage or disposal site. It includes the study of the chemical effects resulting from the absorption of radiation within living animals, plants, and other materials. The radiation chemistry controls much of radiation biology as radiation has an effect on living things at the molecular scale. To explain it another way, the radiation alters th ...

Commissariat à L'énergie Atomique Et Aux énergies Alternatives
The French Alternative Energies and Atomic Energy Commission, or CEA ( French: Commissariat à l'énergie atomique et aux énergies alternatives), is a French public government-funded research organisation in the areas of energy, defense and security, information technologies and health technologies. The CEA maintains a cross-disciplinary culture of engineers and researchers, building on the synergies between fundamental and technological research. CEA is headed by a board headed by the general administrator (currently François Jacq since 20 April 2018), advised by the high-commissioner for atomic energy (currently ). Its yearly budget amounts to €5.8 billion and its permanent staff is slightly over 21,000 persons. History CEA was created in 1945; since then, the successive high-commissioners have been Frédéric Joliot-Curie, Francis Perrin, , , Raoul Dautry, René Pellat, Bernard Bigot, Catherine Cesarsky, , and François Jacq. In December 2009, French President Ni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
École Polytechnique
(, ; also known as Polytechnique or l'X ) is a ''grande école'' located in Palaiseau, France. It specializes in science and engineering and is a founding member of the Polytechnic Institute of Paris. The school was founded in 1794 by mathematician Gaspard Monge during the French Revolution and was militarized under Napoleon I in 1804. It is still supervised by the Ministry of Armed Forces (France), French Ministry of Armed Forces. Originally located in the Latin Quarter, Paris, Latin Quarter in central Paris, the institution moved to Palaiseau in 1976, in the Paris-Saclay, Paris-Saclay technology cluster. French engineering students undergo initial military training and have the status of paid Aspirant, officer cadets. The school has also been awarding doctorates since 1985, masters since 2005 and bachelors since 2017. Most Polytechnique engineering graduates go on to become top executives in companies, senior civil servants, military officers, or researchers. List of É ...

Legion Of Honour
The National Order of the Legion of Honour ( ), formerly the Imperial Order of the Legion of Honour (), is the highest and most prestigious French national order of merit, both military and Civil society, civil. Currently consisting of five classes, it was originally established in 1802 by Napoleon, Napoleon Bonaparte, and it has been retained (with occasional slight alterations) by all later French governments and regimes. The order's motto is ' ("Honour and Fatherland"); its Seat (legal entity), seat is the Palais de la Légion d'Honneur next to the Musée d'Orsay, on the left bank of the Seine in Paris. Since 1 February 2023, the Order's grand chancellor has been retired General François Lecointre, who succeeded fellow retired General Benoît Puga in office. The order is divided into five degrees of increasing distinction: ' (Knight), ' (Officer), ' (Commander (order), Commander), ' (Grand Officer) and ' (Grand Cross).

Ordre Des Palmes Académiques
A suite, in Western classical music, is an ordered set of instrumental or orchestral/concert band pieces. It originated in the late 14th century as a pairing of dance tunes; and grew in scope so that by the early 17th century it comprised up to five dances, sometimes with a prelude. The separate movements were often thematically and tonally linked. The term can also be used to refer to similar forms in other musical traditions, such as the Turkish fasıl and the Arab nuubaat. In the Baroque era, the suite was an important musical form, also known as ''Suite de danses'', ''Ordre'' (the term favored by François Couperin), ''Partita'', or ''Ouverture'' (after the theatrical "overture" which often included a series of dances) as with the orchestral suites of Christoph Graupner, Telemann and J.S. Bach. During the 18th century, the suite fell out of favour as a cyclical form, giving way to the symphony, sonata and concerto. It was revived in the later 19th century, but in a d ...

Commission On Isotopic Abundances And Atomic Weights
The Commission on Isotopic Abundances and Atomic Weights (CIAAW) is an international scientific committee of the International Union of Pure and Applied Chemistry (IUPAC) under its IUPAC Inorganic Chemistry Division, Division of Inorganic Chemistry. Since 1899, it is entrusted with periodic critical evaluation of atomic weights of chemical elements and other cognate data, such as the Isotope, isotopic composition of elements. The biennial CIAAW Standard atomic weight, Standard Atomic Weights are accepted as the authoritative source in science and appear worldwide on the periodic table wall charts. The use of CIAAW Standard Atomic Weights is also required legally, for example, in calculation of calorific value of natural gas (ISO 6976:1995), or in gravimetric preparation of primary reference standards in gas analysis (ISO 6142:2006). In addition, until 2019 the definition of the Kelvin, the SI unit for thermodynamic temperature, made direct reference to the isotopic composition of ...

Knights Of The Legion Of Honour
A knight is a person granted an honorary title of a knighthood by a head of state (including the pope) or representative for service to the monarch, the church, or the country, especially in a military capacity. The concept of a knighthood may have been inspired by the ancient Greek ''hippeis'' (ἱππεῖς) and Roman ''equites''. In the Early Middle Ages in Western Christian Europe, knighthoods were conferred upon mounted warriors. During the High Middle Ages, a knighthood was considered a class of petty nobility. By the Late Middle Ages, the rank had become associated with the ideals of chivalry, a code of conduct for the perfect Royal court, courtly Christian warrior. Often, a knight was a vassal who served as an elite fighter or a bodyguard for a lord, with payment in the form of land holdings. The lords trusted the knights, who were skilled in Horses in warfare, battle on horseback. In the Middle Ages, a knighthood was closely linked with horsemanship (and especially ...
