This paper is dedicated to the 300th anniversary of Michail Vasil'evič Lomonosov, Russiás first world‐renowned scholar. He was educated in Russia and Germany and founded the first chemical laboratory in the Academy of St. Petersburg. There he carried out many quantitative experiments especially in the field of melting glasses. He argued in favor of a corpuscular structure of matter and explained physical and chemical phenomena on the basis of his theory. He also contributed to the humanities by writing numerous papers about the history of the Russian nation and the grammar and the poetics of the Russian language. In his personal life he also wrote himself poems and odes.  相似文献

The state-of-the-art of transition of the chemical sector producing ozone-depleting substances (ODS) in Russia to non-ozone-depleting substances (NODS) is considered. The review summarizes the studies conducted by the Russian Scientific Center Applied Chemistry (St. Petersburg) and a number of Russian Academy Institutes including substantiation for the production methods of non-ozone-depleting hydrofluorocarbons; the most probable chemical mechanisms of their synthesis; the basis for standard process flow diagrams to be used in their full-scale manufacture; and the information on actual and newly created NODS production facilities in the Russian Federation.__________Published in Russian in Izvestiya Akademii Nauk. Seriya Khimicheskaya, No. 11, pp. 2364–2371, November, 2004.  相似文献

The Russian Federation in January 1993 signed the Parisian “Convention about the prohibition of development, production, accumulation and application of chemical weaponry and about its destruction.” In 1996 Federal target program “The destruction of the reserves of chemical weaponry in the Russian Federation” that has status of presidential was approuved for purposes of the realization of the Convention. The convention came into force on April 29, 1997.  相似文献

Today the term ‘perovskite’ is used to designate the crystalline structure of a wide variety of ABX3 ionic compounds. However, historically this name was used for a specific material, having been coined for a mineral, calcium titanate (CaTiO3). This mineral was discovered in the Ural Mountains, Russia. The first sample of the mineral was transferred from Saint Petersburg to Berlin in 1839 by the Russian mineralogist Alexander Kämmerer, who gave the sample for further investigation to the German mineralogist and crystallographer Gustav Rose. Rose determined its properties and chemical composition and named the mineral after the Russian politician and mineralogist Lev Perovski. The present essay describes the background of this discovery as well as the life stories of the personalities involved.  相似文献

This is the first part of two closely related reviews dealing with the computation of phosphorus-31 nuclear magnetic resonance chemical shifts in a wide series of organophosphorus compounds including complexes, clusters, and bioorganic phosphorus compounds. In particular, the analysis of the accuracy factors, such as substitution effects, solvent effects, vibrational corrections, and relativistic effects, is presented. This review is dedicated to the Full Member of the Russian Academy of Sciences Professor Boris A. Trofimov in view of his invaluable contribution to the field of synthesis, nuclear magnetic resonance, and computation studies of organophosphorus compounds.  相似文献

The analytical laboratories accreditation system (SAAL) began its work in 1992. At first, SAAL was created for laboratories performing quantitative chemical analysis, but its activities have constantly expanded. SAAL presently covers laboratories determining oil and petroleum properties, properties of construction materials, parameters of dangerous and harmful industrial goods, precious stones, rubber, plastic, metals etc. Today, SAAL comprises over 3,000 accredited laboratories, 34 accreditation bodies and over 200 assessors united under the Federal Agency on Technical Regulating and Metrology. Within the Russian Federation, SAAL is recognized by various bodies and organizations as a reliable tool in the demonstration of technical competence of laboratories. This report is devoted to the history of SAAL, describing the separate stages of its development, evolution of its requirements for laboratories and accreditation procedures, the principles on which SAAL was based, and conformity of these principles to the legal requirements of the Russian Federation. Presented at the 3rd International Conference on Metrology, November 2006, Tel Aviv, Israel.  相似文献
