Institute For Radium Research, Vienna
The Institute for Radium Research is an Austrian research institute associated with the Austrian Academy of Sciences, Vienna. The Institute's researchers won multiple Nobel Prizes. Due to the gradual change of interests, "nuclear physics" was added to the institute's name in 1956. Since 2004, it is called the ''Stefan-Meyer-Institute for subatomic physics''. History The Sankt Joachimsthal mines were located within the Austria-Hungary monarchy, and were the largest producers of uranium containing ore at the end of the 19th century. Eduard Suess sent the first samples of pitchblende to Pierre and Marie Curie for their research on radioactive materials. This action was taken after the advice of Franz Serafin Exner. After the discovery of radium, the Austrian industrial Karl Kupelwieser donated 500,000 Austrian kronen to found an institute for research on radium in 1908. After constructing the building for the institute in 1909–1910, the institute was opened on 28 October 191 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Research Institute
A research institute, research centre, or research organization is an establishment founded for doing research. Research institutes may specialize in basic research or may be oriented to applied research. Although the term often implies natural science research, there are also many research institutes in the social science as well, especially for sociological and historical research purposes. Famous research institutes In the early medieval period, several astronomical observatories were built in the Islamic world. The first of these was the 9th-century Baghdad observatory built during the time of the Abbasid caliph al-Ma'mun, though the most famous were the 13th-century Maragheh observatory, and the 15th-century Ulugh Beg Observatory. The Kerala School of Astronomy and Mathematics was a school of mathematics and astronomy founded by Madhava of Sangamagrama in Kerala, India. The school flourished between the 14th and 16th centuries and the original discoveries of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rare-earth Element
The rare-earth elements (REE), also called the rare-earth metals or rare earths, and sometimes the lanthanides or lanthanoids (although scandium and yttrium, which do not belong to this series, are usually included as rare earths), are a set of 17 nearly indistinguishable lustrous silvery-white soft heavy metals. Compounds containing rare earths have diverse applications in electrical and electronic components, lasers, glass, magnetic materials, and industrial processes. The term "rare-earth" is a misnomer because they are not actually scarce, but historically it took a long time to isolate these elements. They are relatively plentiful in the entire Earth's crust (cerium being the 25th-most-abundant element at 68 parts per million, more abundant than copper), but in practice they are spread thinly as trace impurities, so to obtain rare earths at usable purity requires processing enormous amounts of raw ore at great expense; thus the name "rare" earths. Scandium and yttrium are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
University Of Vienna
The University of Vienna (, ) is a public university, public research university in Vienna, Austria. Founded by Rudolf IV, Duke of Austria, Duke Rudolph IV in 1365, it is the oldest university in the German-speaking world and among the largest institutions of higher learning in Europe. The university is associated with 17 List of Nobel laureates, Nobel Prize winners and has been the home to many scholars of historical and academic importance. History Middle Ages to the Enlightenment The university was founded on March 12, 1365, by Rudolf IV, Duke of Austria, hence the name "Alma Mater Rudolphina". After the Charles University in Prague (1347) and Jagiellonian University in Kraków (1364), the University of Vienna is the third oldest university in Central Europe and the oldest university in the contemporary German-speaking world; it remains a question of definition as the Charles University in Prague was German-speaking when founded, too. However, Pope Urban V did not ratify th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marietta Blau
Marietta Blau (29 April 1894 – 27 January 1970) was a Jewish Austrian physicist of the 20th century who pioneered developments of photographic nuclear emulsions to image and accurately measure high-energy nuclear particles and events, significantly advancing the field of particle physics in her time. For this, she was awarded the Lieben Prize by the Österreichische Akademie der Wissenschaften (ÖAW). As a Jew, she became an émigré from Austria because of the 1938 Nazi ''Anschluss'' (annexe), her research continuing from Oslo, onto Mexico and the United States of America before eventually returning to Austria in 1960 where she was awarded the ÖAW Erwin Schrödinger Prize. Blau discovered astronomically originating energy had a disintegrating effect to nuclei. Biography Blau was born on 29 April 1894, in Vienna, to Mayer (Markus) Blau (1854–1919), a k.k. Gerichts advokaten and music publisher, and his wife Florentine Goldzweig. Markus' brother-in-law was the music p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Berta Karlik
Berta Karlik (24 January 1904 – 4 February 1990) was an Austrian physicist. She worked for the University of Vienna, eventually becoming the first female professor at the institution. While working with Ernst Foyn, she published a paper on the radioactivity of seawater. She discovered that the chemical element 85 astatine is a product of natural decay processes. The element was first synthesized in 1940 by Dale R. Corson, K. R. MacKenzie, and Emilio Segrè after several scientists in vain searched for it in radioactive minerals. Biography Early life and education Berta Karlik was born in Vienna to an upper-class family and was home-taught for her elementary education. While being taught at home, she learned to play the piano and speak and write French, Dutch, and English. From 1919 to 1923, she attended the Reform-Realgymnasium. Upon graduating in 1923, she was accepted as a regular student to the Philosophical Faculty at the University of Vienna until 1928, when she received ...

Radioactive Tracer
A radioactive tracer, radiotracer, or radioactive label is a synthetic derivative of a natural compound in which one or more atoms have been replaced by a radionuclide (a radioactive atom). By virtue of its radioactive decay, it can be used to explore the mechanism of chemical reactions by tracing the path that the radioisotope follows from reactants to products. Radiolabeling or radiotracing is thus the radioactive form of isotopic labeling. In biological contexts, experiments that use radioisotope tracers are sometimes called radioisotope feeding experiments. Radioisotopes of hydrogen, carbon, phosphorus, sulfur, and iodine have been used extensively to trace the path of biochemical reactions. A radioactive tracer can also be used to track the distribution of a substance within a natural system such as a cell or tissue, or as a flow tracer to track fluid flow. Radioactive tracers are also used to determine the location of fractures created by hydraulic fracturing in nat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nobel Prize
The Nobel Prizes ( ; ; ) are awards administered by the Nobel Foundation and granted in accordance with the principle of "for the greatest benefit to humankind". The prizes were first awarded in 1901, marking the fifth anniversary of Alfred Nobel, Alfred Nobel's death. The original Nobel Prizes covered five fields: Nobel Prize in Physics, physics, Nobel Prize in Chemistry, chemistry, Nobel Prize in Physiology or Medicine, physiology or medicine, Nobel Prize in Literature, literature, and Nobel Peace Prize, peace, specified in Nobel's will. A sixth prize, the Nobel Memorial Prize in Economic Sciences, Prize in Economic Sciences, was established in 1968 by Sveriges Riksbank (Sweden's central bank) in memory of Alfred Nobel. The Nobel Prizes are widely regarded as the most prestigious awards available in their respective fields.Nobel Prize#Shalev69, Shalev, p. 8. Except in extraordinary circumstances, such as war, all six prizes are given annually. Each recipient, known as a laur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cosmic Ray
Cosmic rays or astroparticles are high-energy particles or clusters of particles (primarily represented by protons or atomic nuclei) that move through space at nearly the speed of light. They originate from the Sun, from outside of the Solar System in our own galaxy, and from distant galaxies. Upon impact with Earth's atmosphere, cosmic rays produce showers of secondary particles, some of which reach the surface, although the bulk are deflected off into space by the magnetosphere or the heliosphere. Cosmic rays were discovered by Victor Hess in 1912 in balloon experiments, for which he was awarded the 1936 Nobel Prize in Physics. Direct measurement of cosmic rays, especially at lower energies, has been possible since the launch of the first satellites in the late 1950s. Particle detectors similar to those used in nuclear and high-energy physics are used on satellites and space probes for research into cosmic rays. Data from the Fermi Space Telescope (2013) have ...

Atmosphere
An atmosphere () is a layer of gases that envelop an astronomical object, held in place by the gravity of the object. A planet retains an atmosphere when the gravity is great and the temperature of the atmosphere is low. A stellar atmosphere is the outer region of a star, which includes the layers above the opaque photosphere; stars of low temperature might have outer atmospheres containing compound molecules. The atmosphere of Earth is composed of nitrogen (78%), oxygen (21%), argon (0.9%), carbon dioxide (0.04%) and trace gases. Most organisms use oxygen for respiration; lightning and bacteria perform nitrogen fixation which produces ammonia that is used to make nucleotides and amino acids; plants, algae, and cyanobacteria use carbon dioxide for photosynthesis. The layered composition of the atmosphere minimises the harmful effects of sunlight, ultraviolet radiation, solar wind, and cosmic rays and thus protects the organisms from genetic damage.

Gamma Ray
A gamma ray, also known as gamma radiation (symbol ), is a penetrating form of electromagnetic radiation arising from high energy interactions like the radioactive decay of atomic nuclei or astronomical events like solar flares. It consists of the shortest wavelength electromagnetic waves, typically shorter than those of X-rays. With frequencies above 30 exahertz () and wavelengths less than 10 picometers (), gamma ray photons have the highest photon energy of any form of electromagnetic radiation. Paul Villard, a French chemist and physicist, discovered gamma radiation in 1900 while studying radiation emitted by radium. In 1903, Ernest Rutherford named this radiation ''gamma rays'' based on their relatively strong penetration of matter; in 1900, he had already named two less penetrating types of decay radiation (discovered by Henri Becquerel) alpha rays and beta rays in ascending order of penetrating power. Gamma rays from radioactive decay are in the energy range ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
