Colmar
Colmar (, ; Alsatian: ' ; German during 1871–1918 and 1940–1945: ') is a city and commune in the Haut-Rhin department and Grand Est region of north-eastern France. The third-largest commune in Alsace (after Strasbourg and Mulhouse), it is the seat of the prefecture of the Haut-Rhin department and of the subprefecture of the Colmar-Ribeauvillé arrondissement. The city is renowned for its well-preserved old town, its numerous architectural landmarks, and its museums, among which is the Unterlinden Museum, which houses the ''Isenheim Altarpiece''. Colmar is situated on the Alsatian Wine Route and considers itself to be the "capital of Alsatian wine" ('). History Colmar was first mentioned by Charlemagne in his chronicle about Saxon wars. This was the location where the Carolingian Emperor Charles the Fat held a diet in 884. Colmar was granted the status of a free imperial city by Emperor Frederick II in 1226. In 1354 it joined the Décapole city league.G. Köbler, ''H ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Chemist
A chemist (from Greek ''chÄ“m(Ãa)'' alchemy; replacing ''chymist'' from Medieval Latin ''alchemist'') is a scientist trained in the study of chemistry. Chemists study the composition of matter and its properties. Chemists carefully describe the properties they study in terms of quantities, with detail on the level of molecules and their component atoms. Chemists carefully measure substance proportions, chemical reaction rates, and other chemical properties. In Commonwealth English, pharmacists are often called chemists. Chemists use their knowledge to learn the composition and properties of unfamiliar substances, as well as to reproduce and synthesize large quantities of useful naturally occurring substances and create new artificial substances and useful processes. Chemists may specialize in any number of subdisciplines of chemistry. Materials scientists and metallurgists share much of the same education and skills with chemists. The work of chemists is often related to the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Université Lille Nord De France
The Community of Universities and Institutions (COMUE) Lille Nord de France (formerly Université Lille Nord de France) was a French Groups of Universities and Institutions ( COMUE) spread over multiple campuses and centered in Lille (North - Hauts-de-France). It included a European Doctoral College and federated universities, engineering schools and research centers. With more than one hundred thousand students, it was one of the largest university federations in France. The University of Lille, with nearly 70,000 students, was its main component. The COMUE stopped its activity in 2019 and its activities were transferred to its founding institutions. History Founded as University of Douai in 1562, the university was renamed ''Université impériale de Douai-Lille'' in 1808, then as ''Université de Lille'' with faculty expansion in the Lille region from mid-19th century onwards. * The roots of the faculties in law and humanities date back from the 16th century; * The school of ...

Ostwald Process
The Ostwald process is a chemical process used for making nitric acid (HNO3). Wilhelm Ostwald developed the process, and he patented it in 1902. The Ostwald process is a mainstay of the modern chemical industry, and it provides the main raw material for the most common type of fertilizer production. Historically and practically, the Ostwald process is closely associated with the Haber process, which provides the requisite raw material, ammonia (NH3). Description Stage 1 Ammonia is converted to nitric acid in 2 stages. It is oxidized by heating with oxygen in the presence of a catalyst such as platinum with 10% rhodium, platinum metal on fused silica wool, copper or nickel, to form nitric oxide (nitrogen(II) oxide) and water (as steam). This reaction is strongly exothermic, making it a useful heat source once initiated: :4 NH3 (g) + 5 O2 (g) -> 4 NO (g) + 6 H2O (g) (Δ''H'' = −905.2 kJ/mol) Stage 2 Stage two encompasses two reactions and is carried out in an absorption a ...

Pechiney
Pechiney SA was a major aluminium conglomerate based in France. The company was acquired in 2003 by the Alcan Corporation, headquartered in Canada. In 2007, Alcan itself was taken over by mining giant Rio Tinto Alcan. Prior to its acquisition, Pechiney grew to be the world's 4th largest producer and developer of aluminium products, employing 34,000 people and operating 320 manufacturing and sales facilities in 50 countries at the time it was purchased by Alcan. The group operated in all facets of the aluminium industry from bauxite mining to the development of sophisticated applications of metal products in addition to international commodities trading and brokerage of the metal on the London Metal Exchange (LME). Pechiney gained worldwide recognition for its use of electrolysis technology, and was a leader in specialty packaging and aerospace applications.

People From Colmar
A person ( : people) is a being that has certain capacities or attributes such as reason, morality, consciousness or self-consciousness, and being a part of a culturally established form of social relations such as kinship, ownership of property, or legal responsibility. The defining features of personhood and, consequently, what makes a person count as a person, differ widely among cultures and contexts. In addition to the question of personhood, of what makes a being count as a person to begin with, there are further questions about personal identity and self: both about what makes any particular person that particular person instead of another, and about what makes a person at one time the same person as they were or will be at another time despite any intervening changes. The plural form "people" is often used to refer to an entire nation or ethnic group (as in "a people"), and this was the original meaning of the word; it subsequently acquired its use as a plural form of per ...

19th-century French Chemists
The 19th (nineteenth) century began on 1 January 1801 ( MDCCCI), and ended on 31 December 1900 ( MCM). The 19th century was the ninth century of the 2nd millennium. The 19th century was characterized by vast social upheaval. Slavery was abolished in much of Europe and the Americas. The First Industrial Revolution, though it began in the late 18th century, expanding beyond its British homeland for the first time during this century, particularly remaking the economies and societies of the Low Countries, the Rhineland, Northern Italy, and the Northeastern United States. A few decades later, the Second Industrial Revolution led to ever more massive urbanization and much higher levels of productivity, profit, and prosperity, a pattern that continued into the 20th century. The Islamic gunpowder empires fell into decline and European imperialism brought much of South Asia, Southeast Asia, and almost all of Africa under colonial rule. It was also marked by the collapse of the large S ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
