Alsace
Alsace (, ; ; Low Alemannic German/ gsw-FR, Elsàss ; german: Elsass ; la, Alsatia) is a cultural region and a territorial collectivity in eastern France, on the west bank of the upper Rhine next to Germany and Switzerland. In 2020, it had a population of 1,898,533. Alsatian culture is characterized by a blend of Germanic and French influences. Until 1871, Alsace included the area now known as the Territoire de Belfort, which formed its southernmost part. From 1982 to 2016, Alsace was the smallest administrative ''région'' in metropolitan France, consisting of the Bas-Rhin and Haut-Rhin departments. Territorial reform passed by the French Parliament in 2014 resulted in the merger of the Alsace administrative region with Champagne-Ardenne and Lorraine to form Grand Est. On 1 January 2021, the departments of Bas-Rhin and Haut-Rhin merged into the new European Collectivity of Alsace but remained part of the region Grand Est. Alsatian is an Alemannic dialect closely related ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Buchenwald Concentration Camp
Buchenwald (; literally 'beech forest') was a Nazi concentration camp established on hill near Weimar, Germany, in July 1937. It was one of the first and the largest of the concentration camps within Germany's 1937 borders. Many actual or suspected communists were among the first internees. Prisoners came from all over Europe and the Soviet Union—Jews, Poles and other Slavs, the mentally ill and physically disabled, political prisoners, Romani people, Freemasons, and prisoners of war. There were also ordinary criminals and sexual "deviants". All prisoners worked primarily as forced labor in local armaments factories. The insufficient food and poor conditions, as well as deliberate executions, led to 56,545 deaths at Buchenwald of the 280,000 prisoners who passed through the camp and its 139 subcamps. The camp gained notoriety when it was liberated by the United States Army in April 1945; Allied commander Dwight D. Eisenhower visited one of its subcamps. From August 194 ...

Legion Of Honour
The National Order of the Legion of Honour (french: Ordre national de la Légion d'honneur), formerly the Royal Order of the Legion of Honour ('), is the highest French order of merit, both military and civil. Established in 1802 by Napoleon, Napoleon Bonaparte, 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. The order is divided into five degrees of increasing distinction: ' (Knight), ' (Officer), ' (Commander (order), Commander), ' (Grand Officer) and ' (Grand Cross). History Consulate During the French Revolution, all of the French Order of chivalry, orders of chivalry were abolished and replaced with Weapons of Honour.

Bundesverdienstkreuz
The Order of Merit of the Federal Republic of Germany (german: Verdienstorden der Bundesrepublik Deutschland, or , BVO) is the only federal decoration of Germany. It is awarded for special achievements in political, economic, cultural, intellectual or honorary fields. It was created by the first President of the Federal Republic of Germany, Theodor Heuss, on 7 September 1951. Colloquially, the decorations of the different classes of the Order are also known as the Federal Cross of Merit (). It has been awarded to over 200,000 individuals in total, both Germans and foreigners. Since the 1990s, the number of annual awards has declined from over 4,000, first to around 2,300–2,500 per year, and now under 2,000, with a low of 1752 in 2011. Since 2013, women have made up a steady 30–35% of recipients. Most of the German federal states (''Länder'') have each their own order of merit as well, with the exception of the Free and Hanseatic Cities of Bremen and Hamburg, which reject ...

Croix De Guerre 1939–1945
The ''Croix de Guerre 1939–1945'' (English: War Cross 1939–1945) is a French military decoration, a version of the ''Croix de Guerre'' created on 26 September 1939 to honour people who fought with the Allies against the Axis forces at any time during World War II. After Germany invaded and overran mainland France in the Battle of France in May and June 1940, this ''Croix de Guerre'' was replaced by the pro-Axis Vichy French government with another ''Croix'' with a black-and-green ribbon, while the original was upheld by Free France. Since the triumph of the Free French side in World War II, this version is the only one officially recognized by the French government. Award statute Due to the large extent of the war zone, recipients included those who fought during, with, at, or in the following: * Battle of France * French Forces of the Interior * Free French Forces * Western Front * Middle East Theater * Mediterranean Theater * African campaigns Award description Medal ...

Sodium-ion Battery
The sodium-ion battery (NIB or SIB) is a type of rechargeable battery that uses sodium ions (Na+) as its charge carriers. Its working principle and cell construction are almost identical with those of lithium-ion battery (LIB) types, but replace lithium with sodium. Sodium-ion batteries are a potential alternative to lithium-based battery technologies, largely due to sodium's lower cost and greater availability. Since SIBs use abundant and cheap materials, they are expected to be less expensive than LIBs. The environmental impacts of SIBs are also lower. Although SIBs are heavier and larger than LIBs, they are feasible for stationary energy storage systems where the weight and volume are less crucial. SIBs received academic and commercial interest in the 2010s and 2020s, largely due to the uneven geographic distribution, high environmental impact and high cost of many of the materials required for lithium-ion batteries. Chief among these are lithium, cobalt, copper and nickel, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fluoride
Fluoride (). According to this source, is a possible pronunciation in British English. is an inorganic, monatomic anion of fluorine, with the chemical formula (also written ), whose salts are typically white or colorless. Fluoride salts typically have distinctive bitter tastes, and are odorless. Its salts and minerals are important chemical reagents and industrial chemicals, mainly used in the production of hydrogen fluoride for fluorocarbons. Fluoride is classified as a weak base since it only partially associates in solution, but concentrated fluoride is corrosive and can attack the skin. Fluoride is the simplest fluorine anion. In terms of charge and size, the fluoride ion resembles the hydroxide ion. Fluoride ions occur on Earth in several minerals, particularly fluorite, but are present only in trace quantities in bodies of water in nature. Nomenclature Fluorides include compounds that contain ionic fluoride and those in which fluoride does not dissociate. The nom ...

Neil Bartlett (chemist)
Neil Bartlett (15 September 1932 – 5 August 2008) was a chemist who specialized in fluorine and compounds containing fluorine, and became famous for creating the first noble gas compounds. He taught chemistry at the University of British Columbia and the University of California, Berkeley. Biography Neil Bartlett was born on 15 September 1932 in Newcastle-upon-Tyne, England. Bartlett's interest in chemistry dated back to an experiment at Heaton Grammar School when he was only eleven years old, in which he prepared "beautiful, well-formed" crystals by reaction of aqueous ammonia with copper sulfate. He explored chemistry by constructing a makeshift lab in his parents' home using chemicals and glassware he purchased from a local supply store. He went on to attend King's College, University of Durham (which went on to become Newcastle University) in the United Kingdom where he obtained a Bachelor of Science (1954) and then a doctorate (1958). In 1958, Bartlett's career began up ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nevill Francis Mott
Sir Nevill Francis Mott (30 September 1905 – 8 August 1996) was a British physicist who won the Nobel Prize for Physics in 1977 for his work on the electronic structure of magnetic and disordered systems, especially amorphous semiconductors. The award was shared with Philip W. Anderson and J. H. Van Vleck. The three had conducted loosely related research. Mott and Anderson clarified the reasons why magnetic or amorphous materials can sometimes be metallic and sometimes insulating. Education and early life Mott was born in Leeds to Lilian Mary Reynolds and Charles Francis Mott and grew up first in the village of Giggleswick, in the West Riding of Yorkshire, where his father was Senior Science Master at Giggleswick School. His mother also taught Maths at the School. The family moved (due to his father's jobs) first to Staffordshire, then to Chester and finally Liverpool, where his father had been appointed Director of Education. Mott was at first educated at home by his mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
