Yuri A. Barbanel
Yuri A. Barbanel (also Yuri A. Barbanel’, Yury Abramovich Barbanel) (8 April 1935 – 2 August 2016) was a distinguished Russians, Russian chemist born in 1935 in Leningrad (now St. Petersburg). He obtained a Master of Science in chemistry from A. A. Zhdanov Leningrad State University, now Saint Petersburg State University, in 1958 and his Doctor of Philosophy, Ph.D. in 1964 and his Doctor of Science, D.Sc. in 1991. Barbanel was a scientist in the fundamental radiochemistry branch of the V.G. Khlopin Radium Institute in St. Petersburg until his retirement in 2011. His research interests included Visible spectrum, optical spectra induced by radioluminescence and Complex (chemistry), coordination chemistry of the actinides, and absorption spectra of the actinides in molten salts.

Leningrad
Saint Petersburg ( rus, links=no, Санкт-Петербург, a=Ru-Sankt Peterburg Leningrad Petrograd Piter.ogg, r=Sankt-Peterburg, p=ˈsankt pʲɪtʲɪrˈburk), formerly known as Petrograd (1914–1924) and later Leningrad (1924–1991), is the second-largest city in Russia. It is situated on the Neva River, at the head of the Gulf of Finland on the Baltic Sea, with a population of roughly 5.4 million residents. Saint Petersburg is the fourth-most populous city in Europe after Istanbul, Moscow and London, the most populous city on the Baltic Sea, and the world's northernmost city of more than 1 million residents. As Russia's Imperial capital, and a historically strategic port, it is governed as a federal city. The city was founded by Tsar Peter the Great on 27 May 1703 on the site of a captured Swedish fortress, and was named after apostle Saint Peter. In Russia, Saint Petersburg is historically and culturally associated with ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Radioluminescence
Radioluminescence is the phenomenon by which light is produced in a material by bombardment with ionizing radiation such as alpha particles, beta particles, or gamma rays. Radioluminescence is used as a low level light source for night illumination of instruments or signage. Radioluminescent paint is occasionally used for clock hands and instrument dials, enabling them to be read in the dark. Radioluminescence is also sometimes seen around high-power radiation sources, such as nuclear reactors and radioisotopes. Mechanism Radioluminescence occurs when an incoming particle of ionizing radiation collides with an atom or molecule, exciting an orbital electron to a higher energy level. The particle usually comes from the radioactive decay of an atom of a radioisotope, an isotope of an element which is radioactive. The electron then returns to its ground energy level by emitting the extra energy as a photon of light. A chemical that releases light of a particular color when ...

Abravanel Family
The Abravanel family ( he, ''ʾAbravanʾēl'' or ''ʾAbarbənəʾēl''), also spelled as ''Abarbanel'', ''Abrabanel'', ''Avravanel'', ''Barbernell'', or ''Barbanel'' – literally meaning ''Ab'' ("father") ''rabban'' ("priest") ''el'' ("of God") – is one of the oldest and most distinguished Jewish families. It first achieved prominence on the Iberian peninsula during the Middle Ages. Its members claim to trace their origin to the biblical King David. Members of this family lived in Seville, Córdoba (Spanish province), Castile-Leon, and Calatayud. Seville is where its most prominent representative, Don Judah Abravanel, once dwelt. Don Judah Abravanel was treasurer and tax-collector under Sancho IV (1284–95) and Ferdinand IV (1295–1312). In 1310 he and other Jews guaranteed the loans made to the crown of Castile to finance the siege of Algeciras. It is probable that he was almoxarife ("collector of revenues") of Castile. Don Judah Abravanel and his family later fled to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Soviet Jews
The history of the Jews in the Soviet Union is inextricably linked to much earlier expansionist policies of the Russian Empire conquering and ruling the eastern half of the European continent already before the Bolshevik Revolution of 1917. "For two centuries – wrote Zvi Gitelman – millions of Jews had lived under one entity, the Russian Empire and its successor state the USSR. They had now come under the jurisdiction of fifteen states, some of which had never existed and others that had passed out of existence in 1939." Before the revolutions of 1989 which resulted in the end of communist rule in Central and Eastern Europe, a number of these now sovereign countries constituted the component republics of the Soviet Union. Armenia The history of the Jews in Armenia dates back more than 2,000 years. After Eastern Armenia came under Russian rule in the early 19th century, Jews began arriving from Poland and Iran, creating Ashkenazic and Mizrahi communities in Yerevan. More Jews ...

Scientists From Saint Petersburg
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 Terminal degree, advanced degrees in an area of science and pursue careers in various Sector (economic), sectors of the economy such as Academy, academia, Private industry, industry, Government sci ...

Absorption Spectra
Absorption spectroscopy refers to spectroscopic techniques that measure the absorption of radiation, as a function of frequency or wavelength, due to its interaction with a sample. The sample absorbs energy, i.e., photons, from the radiating field. The intensity of the absorption varies as a function of frequency, and this variation is the absorption spectrum. Absorption spectroscopy is performed across the electromagnetic spectrum. Absorption spectroscopy is employed as an analytical chemistry tool to determine the presence of a particular substance in a sample and, in many cases, to quantify the amount of the substance present. Infrared and ultraviolet–visible spectroscopy are particularly common in analytical applications. Absorption spectroscopy is also employed in studies of molecular and atomic physics, astronomical spectroscopy and remote sensing. There is a wide range of experimental approaches for measuring absorption spectra. The most common arrangement is to direct ...

Actinide
The actinide () or actinoid () series encompasses the 15 metallic chemical elements with atomic numbers from 89 to 103, actinium through lawrencium. The actinide series derives its name from the first element in the series, actinium. The informal chemical symbol An is used in general discussions of actinide chemistry to refer to any actinide. The 1985 IUPAC ''Red Book'' recommends that ''actinoid'' be used rather than ''actinide'', since the suffix ''-ide'' normally indicates a negative ion. However, owing to widespread current use, ''actinide'' is still allowed. Since ''actinoid'' literally means ''actinium-like'' (cf. ''humanoid'' or ''android''), it has been argued for semantic reasons that actinium cannot logically be an actinoid, but IUPAC acknowledges its inclusion based on common usage. All the actinides are f-block elements, except the final one (lawrencium) which is a d-block element. Actinium has sometimes been considered d-block instead of lawrencium, but the class ...
