Paul Kogerman
Paul Nikolai Kogerman ( in Tallinn – 27 July 1951 in Tallinn) was an Estonian chemist and founder of modern research in oil shale. Paul Kogerman was born into a family of gas factory worker (and former sailor). He went to an elementary school in 1901–1904 and a town school in 1904–1908. After town school Kogerman earned a living by teaching in church manors near Tallinn. In 1913, he was graduated from the Alexander Gymnasium in Tallinn (Reval) as an extern. Starting in 1913, he studied at the University of Tartu, graduating from its Department of Chemistry in 1918. In the Estonian War of Independence he fought in a unit of Tallinn teachers. In 1919–1920 he got a state scholarship to study at the Imperial College London. In May 1921 he was given a qualification of chemical technologist by the University of London and in 1922 he received the degree of Master of Sciences. Career From 1921 to 1936, Kogerman was active at the University of Tartu. After the defence of his ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tallinn
Tallinn () is the most populous and capital city of Estonia. Situated on a bay in north Estonia, on the shore of the Gulf of Finland of the Baltic Sea, Tallinn has a population of 437,811 (as of 2022) and administratively lies in the Harju ''maakond'' (county). Tallinn is the main financial, industrial, and cultural centre of Estonia. It is located northwest of the country's second largest city Tartu, however only south of Helsinki, Finland, also west of Saint Petersburg, Russia, north of Riga, Latvia, and east of Stockholm, Sweden. From the 13th century until the first half of the 20th century, Tallinn was known in most of the world by variants of its other historical name Reval. Tallinn received Lübeck city rights in 1248,, however the earliest evidence of human population in the area dates back nearly 5,000 years. The medieval indigenous population of what is now Tallinn and northern Estonia was one of the last " pagan" civilisations in Europe to adopt Christianit ...

Master Of Science
A Master of Science ( la, Magisterii Scientiae; abbreviated MS, M.S., MSc, M.Sc., SM, S.M., ScM or Sc.M.) is a master's degree in the field of science awarded by universities in many countries or a person holding such a degree. In contrast to the Master of Arts degree, the Master of Science degree is typically granted for studies in sciences, engineering and medicine and is usually for programs that are more focused on scientific and mathematical subjects; however, different universities have different conventions and may also offer the degree for fields typically considered within the humanities and social sciences. While it ultimately depends upon the specific program, earning a Master of Science degree typically includes writing a thesis. The Master of Science degree was first introduced at the University of Michigan in 1858. One of the first recipients of the degree was De Volson Wood, who was conferred a Master of Science degree at the University of Michigan in 1859. Al ...

Institute Of Petroleum
The Institute of Petroleum (IP) was a UK-based professional organisation founded in 1913 as the Institute of Petroleum Technologists. It changed its name to the Institute of Petroleum in 1938. The institute became defunct when it merged with the Institute of Energy in 2003 to form the Energy Institute. Background The Institute of Petroleum Technologists was established in 1913 by the consulting chemist and engineer Sir (Thomas) Redwood baronets, Boverton Redwood (1846–1919) and Arthur Eastlake. At the institute's inaugural meeting in 1914 Sir Thomas stated that the aim of the institute was to determine a “hallmark of proficiency in connection with our profession". He emphasised the need to amalgamate the diverse knowledge and interests of the various branches of the oil industry. In 1938 the institute changed its name to the Institute of Petroleum and membership was opened to all professions associated with the oil and gas industries.

Diene
In organic chemistry a diene ( ) (diolefin ( ) or alkadiene) is a covalent compound that contains two double bonds, usually among carbon atoms. They thus contain two alk''ene'' units, with the standard prefix ''di'' of systematic nomenclature. As a subunit of more complex molecules, dienes occur in naturally occurring and synthetic chemicals and are used in organic synthesis. Conjugated dienes are widely used as monomers in the polymer industry. Polyunsaturated fats are of interest to nutrition. Classes Dienes can be divided into three classes, depending on the relative location of the double bonds: #Cumulated dienes have the double bonds sharing a common atom. The result is more specifically called an allene. #Conjugated dienes have conjugated double bonds separated by one single bond. Conjugated dienes are more stable than other dienes because of resonance. #Unconjugated dienes have the double bonds separated by two or more single bonds. They are usually less stable tha ...

Covalent Bond
A covalent bond is a chemical bond that involves the sharing of electrons to form electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs. The stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding. For many molecules, the sharing of electrons allows each atom to attain the equivalent of a full valence shell, corresponding to a stable electronic configuration. In organic chemistry, covalent bonding is much more common than ionic bonding. Covalent bonding also includes many kinds of interactions, including σ-bonding, π-bonding, metal-to-metal bonding, agostic interactions, bent bonds, three-center two-electron bonds and three-center four-electron bonds. The term ''covalent bond'' dates from 1939. The prefix ''co-'' means ''jointly, associated in action, partnered to a lesser degree, '' etc.; thus a "co-valent bond", in essence, means that the atoms share " valence", such a ...

Polymerization
In polymer chemistry, polymerization (American English), or polymerisation (British English), is a process of reacting monomer, 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 free-radical reaction, radical reactions; in contrast, reactions involving substitution at a carbonyl group require more complex synthesis due to the way in which reactants polymerize. Alkanes can also be polymerized, but only with the help of strong acids. As alkenes can polymerize in somewhat straightforward radical reactions, they form useful compounds such as polyethylene and p ...
