Walter Kaminsky
Walter Kaminsky (7 May 1941 – 23 November 2024) was a German chemist who specialised in olefin polymerization and plastic recycling. He discovered the high activity of Group 4 metallocene/ methylaluminoxane (MAO) mixtures (later named the Kaminsky catalyst) as catalysts for olefin polymerization in 1980. Life and career Kaminsky was born in Hamburg, Germany on 7 May 1941. He studied chemistry at the University of Hamburg. He received his PhD under Hansjörg Sinn in 1978 and obtained his habilitation in 1982, both at the University of Hamburg. He was a faculty member at the University of Hamburg The University of Hamburg (, also referred to as UHH) is a public university, public research university in Hamburg, Germany.

Olefin
In organic chemistry, an alkene, or olefin, is a hydrocarbon containing a carbon–carbon double bond. The double bond may be internal or at the terminal position. Terminal alkenes are also known as α-olefins. The International Union of Pure and Applied Chemistry (IUPAC) recommends using the name "alkene" only for acyclic hydrocarbons with just one double bond; alkadiene, alkatriene, etc., or polyene for acyclic hydrocarbons with two or more double bonds; cycloalkene, cycloalkadiene, etc. for cyclic ones; and "olefin" for the general class – cyclic or acyclic, with one or more double bonds. Acyclic alkenes, with only one double bond and no other functional groups (also known as mono-enes) form a homologous series of hydrocarbons with the general formula with ''n'' being a >1 natural number (which is two hydrogens less than the corresponding alkane). When ''n'' is four or more, isomers are possible, distinguished by the position and conformation of the double bond. A ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The Franklin Institute Awards
The Franklin Institute Awards (or Benjamin Franklin Medal) is an American science and engineering award presented by the Franklin Institute, a science museum in Philadelphia. The Franklin Institute awards comprises the Benjamin Franklin Medals in seven areas of science and engineering, the Bower Awards and Prize for Achievement in Science, and the Bower Award for Business Leadership.

Academic Staff Of The University Of Hamburg
An academy (Attic Greek: Ἀκαδήμεια; Koine Greek Ἀκαδημία) is an institution of tertiary education. The name traces back to Plato's school of philosophy, founded approximately 386 BC at Akademia, a sanctuary of Athena, the goddess of wisdom and Skills, skill, north of Ancient Athens, Athens, Greece. The Royal Spanish Academy defines academy as scientific, literary or artistic society established with public authority and as a teaching establishment, public or private, of a professional, artistic, technical or simply practical nature. Etymology The word comes from the ''Academy'' in ancient Greece, which derives from the Athenian hero, ''Akademos''. Outside the city walls of Athens, the Gymnasium (ancient Greece), gymnasium was made famous by Plato as a center of learning. The sacred space, dedicated to the goddess of wisdom, Athena, had formerly been an olive Grove (nature), grove, hence the expression "the groves of Academe". In these gardens, the philos ...

Scientists From Hamburg
A scientist is a person who researches 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 ( 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. History The roles of "scientists", and their predecessors before the emergence of modern scientific disciplines, have evolved considerably over time. Scientists of different eras (and before them, natural philosophers, mathematicians, natur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

1941 Births
The Correlates of War project estimates this to be the deadliest year in human history in terms of conflict deaths, placing the death toll at 3.49 million. However, the Uppsala Conflict Data Program estimates that the subsequent year, 1942, was the deadliest such year. Death toll estimates for both 1941 and 1942 range from 2.28 to 7.71 million each.

Körber European Science Prize
The Körber European Science Prize is a science and technology award, presented annually by the Körber Foundation in Hamburg, honoring outstanding scientists working in Europe for their promising research projects. The prize is endowed with 1 million euro (until 2018: 750,000 euro) and promotes research projects in the life sciences and physical sciences. History The prize was initiated by the entrepreneur Kurt A. Körber with the help of Reimar Lüst, the president of the Max Planck Society. The first award was in 1985. At first, European research teams were honored, but since 2005, only individuals qualify. Selection process Candidates for the prize need not be from Europe, but they must be living in Europe. Renowned scientists from all over Europe, grouped into two Search Committees, select promising candidates. The awards are annual and alternate between the life and physical sciences. Those who are shortlisted are then asked to submit a detailed proposal for a research pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Polymerization
In polymer chemistry, polymerization (American English), or polymerisation (British English), is a process of reacting monomer molecules together in a chemical reaction to form polymer chains or three-dimensional networks. There are many forms of polymerization and different systems exist to categorize them. In chemical compounds, polymerization can occur via a variety of reaction mechanisms that vary in complexity due to the functional groups present in the reactants and their inherent steric effects. In more straightforward polymerizations, alkenes form polymers through relatively simple radical reactions; in contrast, reactions involving substitution at a carbonyl group require more complex synthesis due to the way in which reactants polymerize. As alkenes can polymerize in somewhat straightforward radical reactions, they form useful compounds such as polyethylene and polyvinyl chloride (PVC), which are produced in high tonnages each year due to their usefulnes ...
