Boris Mamyrin
Boris Aleksandrovich Mamyrin (russian: Борис Александрович Мамырин; 25 May 1919 5 March 2007) was a Soviet scientist best known for his invention of the electrostatic ion mirror mass spectrometer known as the reflectron. Biography Mamyrin was born in 1919 in Lipetsk, Soviet Russia during Russian civil war. Both of his parents were medical doctors and his early aim was to follow in their footsteps. However, shortly after he obtained his M.S. degree in physics from the Leningrad Polytechnic Institute, World War II cut his studies short. He served in the army throughout the war, finally discharging from military service in 1948. He returned to the Polytechnic Institute and obtained his doctoral degree within a year. He was the head and leading research scientist of the laboratory for mass spectrometry at Ioffe Physico-Technical Institute of the Russian Academy of Sciences. He was a corresponding member of the Russian Academy of Sciences and a full member of t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lipetsk, Russia
Lipetsk ( rus, links=no, Липецк, p=ˈlʲipʲɪtsk), also romanized as Lipeck, is a city and the administrative center of Lipetsk Oblast, Russia, located on the banks of the Voronezh River in the Don basin, southeast of Moscow. Population: History Lipetsk was first mentioned in the 13th century chronicles. The name means " Linden city" and is cognate with Leipzig and Liepāja. In 1284, the city was destroyed by the Mongols. The foundation of the modern city dates back to 1703,Charter of Lipetsk, Article 1 when Peter the Great ordered construction of a cast iron factory in Lipetsk near the iron ore deposits for making artillery shells. On September 27, 1779, Lipetsk was granted town status. It became one of the principal towns of Tambov Governorate. In 1879, Lipetsk hosted a congress of members of Land and Liberty. After the Treaty of Rapallo (1922) until 1933, the much-reduced German Army (''Reichswehr'') of the Weimar Republic secretly contracted with S ...

Mass Spectrometrists
Mass is an intrinsic property of a body. It was traditionally believed to be related to the quantity of matter in a physical body, until the discovery of the atom and particle physics. It was found that different atoms and different elementary particles, theoretically with the same amount of matter, have nonetheless different masses. Mass in modern physics has multiple definitions which are conceptually distinct, but physically equivalent. Mass can be experimentally defined as a measure of the body's inertia, meaning the resistance to acceleration (change of velocity) when a net force is applied. The object's mass also determines the strength of its gravitational attraction to other bodies. The SI base unit of mass is the kilogram (kg). In physics, mass is not the same as weight, even though mass is often determined by measuring the object's weight using a spring scale, rather than balance scale comparing it directly with known masses. An object on the Moon would weigh l ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Time-of-flight Mass Spectrometry
Time-of-flight mass spectrometry (TOFMS) is a method of mass spectrometry in which an ion's mass-to-charge ratio is determined by a time of flight measurement. Ions are accelerated by an electric field of known strength. This acceleration results in an ion having the same kinetic energy as any other ion that has the same charge. The velocity of the ion depends on the mass-to-charge ratio (heavier ions of the same charge reach lower speeds, although ions with higher charge will also increase in velocity). The time that it subsequently takes for the ion to reach a detector at a known distance is measured. This time will depend on the velocity of the ion, and therefore is a measure of its mass-to-charge ratio. From this ratio and known experimental parameters, one can identify the ion. Theory The potential energy of a charged particle in an electric field is related to the charge of the particle and to the strength of the electric field: where ''E''p is potential energy, ''q'' ...

Russian Academy Of Natural Sciences
The Russian Academy of Natural Sciences (Russian: Российская академия естественных наук) is a Russian non-governmental organization founded on August 31 1990 in Moscow in the former Soviet Union, following a decree by the Supreme Soviet of Russia. , the Academy operates under the Federal Law of August 23, 1996 No. 127-FZ "On Science and State Scientific-Technical Politics". The academy states that it seeks to unite scholars in different fields for the betterment of Russia. As of 2020, its president is Oleg Leonidovich Kuznetsov and its Vice President and Chief Secretary is Lida Vladimirovna Ivanitskaya. The academy is not associated with the Russian Academy of Sciences. It has been criticised because many members lack scientific credentials and some espouse pseudoscientific theories such as Aušra Augustinavičiūtė's socionics and Anatoly Fomenko's " New Chronology".Опасность лженауки("Danger of Pseudoscience") Currently, the ...

Russian Academy Of Sciences
The Russian Academy of Sciences (RAS; russian: Росси́йская акаде́мия нау́к (РАН) ''Rossíyskaya akadémiya naúk'') consists of the national academy of Russia; a network of scientific research institutes from across the Russian Federation; and additional scientific and social units such as libraries, publishing units, and hospitals. Peter the Great established the Academy (then the St. Petersburg Academy of Sciences) in 1724 with guidance from Gottfried Leibniz. From its establishment, the Academy benefitted from a slate of foreign scholars as professors; the Academy then gained its first clear set of goals from the 1747 Charter. The Academy functioned as a university and research center throughout the mid-18th century until the university was dissolved, leaving research as the main pillar of the institution. The rest of the 18th century continuing on through the 19th century consisted of many published academic works from Academy scholars and a few Ac ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mass Spectrometry
Mass spectrometry (MS) is an analytical technique that is used to measure the mass-to-charge ratio of ions. The results are presented as a ''mass spectrum'', a plot of intensity as a function of the mass-to-charge ratio. Mass spectrometry is used in many different fields and is applied to pure samples as well as complex mixtures. A mass spectrum is a type of plot of the ion signal as a function of the mass-to-charge ratio. These spectra are used to determine the elemental or isotopic signature of a sample, the masses of particles and of molecules, and to elucidate the chemical identity or structure of molecules and other chemical compounds. In a typical MS procedure, a sample, which may be solid, liquid, or gaseous, is ionized, for example by bombarding it with a beam of electrons. This may cause some of the sample's molecules to break up into positively charged fragments or simply become positively charged without fragmenting. These ions (fragments) are then separated accordin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
