Hans Falkenhagen
Hans Falkenhagen (13 May 1895 – 26 June 1971) was a German physicist and electrochemist best known for eponymous Debye–Falkenhagen effect. 1955 he became a regular member of the German Academy of Sciences at Berlin and in 1962 a member of the German Academy of Sciences Leopoldina The German National Academy of Sciences Leopoldina (german: Deutsche Akademie der Naturforscher Leopoldina – Nationale Akademie der Wissenschaften), short Leopoldina, is the national academy of Germany, and is located in Halle (Saale).

Debye–Falkenhagen Effect
The increase in the conductivity of an electrolyte solution when the applied voltage has a very high frequency is known as Debye–Falkenhagen effect. Impedance measurements on water-p-dioxane and the methanol-toluene systems have confirmed Falkenhagen's predictions made in 1929. See also *Peter Debye *Debye length *Hans Falkenhagen *Wien effect The Wien effect is the experimentally-observed increase in ionic mobility or conductivity of electrolytes at very high gradient of electrical potential. A theoretical explanation has been proposed by Lars Onsager. A related phenomenon is known as ... References Electrochemical concepts Peter Debye {{Electrochem-stub ...

German Academy Of Sciences At Berlin
The German Academy of Sciences at Berlin, german: Deutsche Akademie der Wissenschaften zu Berlin (DAW), in 1972 renamed the Academy of Sciences of the GDR (''Akademie der Wissenschaften der DDR (AdW)''), was the most eminent research institution of East Germany (German Democratic Republic, GDR). The academy was established in 1946 in an attempt to continue the tradition of the Prussian Academy of Sciences and the Brandenburg Society of Sciences, founded in 1700 by Gottfried Wilhelm Leibniz. The academy was a learned society (scholarship society), in which awarded membership via election constituted scientific recognition. Unlike other academies of science, the DAW was also the host organization of a scientific community of non-academic research institutes. Upon German reunification, the Academy's learned society was dissociated from its research institutes and any other affiliates and eventually dissolved in 1992. Since 1993, activities of the AdW's members and college have been ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Academy Of Sciences Leopoldina
The German National Academy of Sciences Leopoldina (german: Deutsche Akademie der Naturforscher Leopoldina – Nationale Akademie der Wissenschaften), short Leopoldina, is the national academy of Germany, and is located in Halle (Saale). Founded on January 1, 1652, based on academic models in Italy, it was originally named the ''Academia Naturae Curiosorum'' until 1687 when Emperor Leopold I raised it to an academy and named it after himself. It was since known under the German name ''Deutsche Akademie der Naturforscher Leopoldina'' until 2007, when it was declared to be Germany's National Academy of Sciences. History ' The Leopoldina was founded in the imperial city of Schweinfurt on 1 January 1652 under the Latin name sometimes translated into English as "Academy of the Curious as to Nature." It was founded by four local physicians- Johann Laurentius Bausch, the first president of the society, Johann Michael Fehr, Georg Balthasar Metzger, and Georg Balthasar Wohlfarth; and ...

Saxon State Library
The Saxon State and University Library Dresden (full name in german: Sächsische Landesbibliothek – Staats- und Universitätsbibliothek Dresden), abbreviated SLUB Dresden, is located in Dresden, Germany. It is both the regional library (german: Landesbibliothek) for the German State of Saxony as well as the academic library for the Dresden University of Technology (german: Technische Universität Dresden). It was created in 1996 through the merger of the Saxon State Library (SLB) and the University Library Dresden (UB). The seemingly redundant name is to show that the library brings both these institutional traditions together. The SLUB moved into a large new building in 2002 to bring together the inventories of both its predecessors. Its collection numbers nearly nine million, making it one of the largest public archival centers in the Federal Republic of Germany. It holds significant treasures, including the Codex Dresdensis, an octagonal Koran from 1184 and a copy of the Pete ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
