Manfred T. Reetz
Manfred Theodor Reetz (born 13 August 1943) is a German chemist and professor of organic chemistry, who served as director of the Max Planck Institute for Coal Research from 1991 until 2011. His research focuses on directed evolution, enzymes in organic chemistry, and stereoselective biocatalysis. Biography Reetz was born in Hirschberg, Lower Silesia, in 1943 and immigrated to the US in 1952. After studying chemistry at Washington University in St. Louis and the University of Michigan, he returned to Germany to obtain his Ph.D. under Ulrich Schöllkopf at the University of Göttingen. He subsequently worked as a postdoctoral researcher at the University of Marburg where he completed his habilitation in 1978. After two years at the University of Bonn, he returned to Marburg as full professor in 1980. In 1991 he was appointed director of the Max Planck Institute for Coal Research in Mülheim, a position that he held until 2011. Honors and awards Among the awards that Reetz has r ...

Jelenia Góra
Jelenia Góra (pron. ; Polish: ; german: Hirschberg im Riesengebirge; Exonym: ''Deer Mountain''; szl, Jelyniŏ Gōra) is a historic city in southwestern Poland, within the historical region of Lower Silesia. Jelenia Góra is situated in the Lower Silesian Voivodeship, close to the Karkonosze mountain range running along the Polish- Czech border – ski resorts such as Karpacz and Szklarska Poręba are situated from the city. Jelenia Góra constitutes a separate urban gmina as well as being the seat of surrounding Karkonosze County (formerly Jelenia Góra County). In 2021 the population of Jelenia Góra was 77,366. The area, including the oldest spa district of Cieplice Śląskie-Zdrój, is one of the most valued recreational and leisure spots in Poland. The city's history dates back to as early as the 10th century, but the settlement was granted town rights under Polish rule in 1288. Jelenia Góra was founded on important trade routes linking the Holy Roman Empire and Boh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stereoselective
In chemistry, stereoselectivity is the property of a chemical reaction in which a single reactant forms an unequal mixture of stereoisomers during a non- stereospecific creation of a new stereocenter or during a non-stereospecific transformation of a pre-existing one. The selectivity arises from differences in steric and electronic effects in the mechanistic pathways leading to the different products. Stereoselectivity can vary in degree but it can never be total since the activation energy difference between the two pathways is finite. Both products are at least possible and merely differ in amount. However, in favorable cases, the minor stereoisomer may not be detectable by the analytic methods used. An enantioselective reaction is one in which one enantiomer is formed in preference to the other, in a reaction that creates an optically active product from an achiral starting material, using either a chiral catalyst, an enzyme or a chiral reagent. The degree of selectivity is me ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

21st-century German Chemists
The 1st century was the century spanning AD 1 ( I) through AD 100 ( C) according to the Julian calendar. It is often written as the or to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The 1st century also saw the appearance of Christianity. During this period, Europe, North Africa and the Near East fell under increasing domination by the Roman Empire, which continued expanding, most notably conquering Britain under the emperor Claudius (AD 43). The reforms introduced by Augustus during his long reign stabilized the empire after the turmoil of the previous century's civil wars. Later in the century the Julio-Claudian dynasty, which had been founded by Augustus, came to an end with the suicide of Nero in AD 68. There followed the famous Year of Four Emperors, a brief period of civil war and instability, which was finally brought to an end by Vespasian, ninth Roman emperor, ...

Scientists From The Province Of Silesia
A scientist is a person who conducts scientific research to advance knowledge in an area of the natural sciences. In classical antiquity, there was no real ancient analog of a modern scientist. Instead, philosophers engaged in the philosophical study of nature called natural philosophy, a precursor of natural science. Though Thales (circa 624-545 BC) was arguably the first scientist for describing how cosmic events may be seen as natural, not necessarily caused by gods,Frank N. Magill''The Ancient World: Dictionary of World Biography'', Volume 1 Routledge, 2003 it was not until the 19th century that the term ''scientist'' came into regular use after it was coined by the theologian, philosopher, and historian of science William Whewell in 1833. In modern times, many scientists have advanced degrees in an area of science and pursue careers in various sectors of the economy such as academia, industry, government, and nonprofit environments.''''

People From Jelenia Góra
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 p ...

German Academy Of Sciences Leopoldina
The German National Academy of Sciences Leopoldina (german: link=no, 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 1 January 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 Wo ...
