Download or read book Laser-induced Separation of Hydrogen Isotopes in the Liquid Phase written by and published by . This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen isotope separation is achieved by either (a) dissolving a hydrogen-bearing feedstock compound in a liquid solvent, or (b) liquefying a hydrogen-bearing feedstock compound, the liquid phase thus resulting being kept at a temperature at which spectral features of the feedstock relating to a particular hydrogen isotope are resolved, i.e., a clear-cut isotope shift is delineated, irradiating the liquid phase with monochromatic radiation of a wavelength which at least preferentially excites those molecules of the feedstock containing a first hydrogen isotope, inducing photochemical reaction in the excited molecules, and separating the reaction product containing the first isotope from the liquid phase.

Available in PDF, EPUB and Kindle. Book excerpt: Written by leading Russian scientists, including Nobel laureate, A.M. Prokhorov (1916-2002), this first book on this important technology allows an understanding of the physics of atomic vapor laser isotope separation and new photochemical methods of laser isotope separation. One entire chapter is devoted to chemical reactions of atoms in excited states, while further chapters deal with the separation of isotopes by one photon isotope-selective and coherent isotope-selective two photon excitation of atoms. A final chapter looks at the prospects for the industrial production of isotope products by laser isotope separation. The whole is rounded off by six appendices.

This book was released on 2006-12-01 with total page 317 pages. Available in PDF, EPUB and Kindle. Book excerpt: Separation of Isotopes of Biogenic Elements provides a detailed overview of this area of research covering all aspects from the value of isotope effects to their practical use (equilibrium single-stage isotope effect - kinetics and mass transfer – multiplication of the single-stage isotope separation factor - technological peculiarity of processes) with the purpose of extraction from the natural mixture of the enriched and highly concentrated isotopes. In contrast to traditional books on the theory of isotope separation, the theoretical part of the book describes separation in two-phase processes in counter-flow columns. The experimental part of the book presents systematic analysis of specialists in the field of isotope separation in counter-flow columns. This book will be of interest to scientists, engineers and technical workers engaged in isotope separation processes and isotope application in nuclear physics, medicine, agro-chemistry, biology and other areas. This book may also be used in teaching theory and practical aspects in courses on physical chemistry and Isotope separation of light elements by physicochemical methods. * summarises current state of isotope research, especially biogenic elements* covering all aspects from the value of isotope effects to their practical use* of interest to scientists, engineers and technical workers engaged in isotope separation processes and isotope application

Book Synopsis Helium and Hydrogen Isotope Adsorption and Separation in Metal-Organic Frameworks by : Ingrid Zaiser
Download or read book Helium and Hydrogen Isotope Adsorption and Separation in Metal-Organic Frameworks written by Ingrid Zaiser and published by Cuvillier Verlag. This book was released on 2016-10-31 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: The separation of isotopes has always been a challenge because of their identical size, shape and thermodynamic properties. Nowadays, the extraction of deuterium is performed e.g. by the Girdler Sulfid process or cryogenic distillation, which lead to low separation factors (below 2.5) in combination with high energy costs. The standard way to produce helium-3 is to skim it as a byproduct of the radioactive tritium decay. In this thesis, two alternative approaches have been investigated for the separation of light isotopes, Quantum Sieving and Chemical Affinity Sieving . While Quantum Sieving is based on confinement in small pores, Chemical Affinity Sieving relies on strong adsorption sites. Both methods use the mass difference of the isotopes, which is related to their zero-point energy. The microporous metal-organic frameworks are excellent candidates for studying these quantum effects due to their well-defined pore structure and the possibility to introduce strong adsorption sites directly into the framework. The samples have been exposed to an isotope mixture and the adsorbed quantity of each isotope was detected by low-temperature thermal desorption spectroscopy (TDS). The ratio of the desorbed amount of the isotopes leads directly to the selectivity (separation factor). The selectivity is determined as a function of exposure time and temperature and exhibits the highest value of 25 observed for hydrogen isotopes at temperatures well above the boiling point of liquid nitrogen.
Book Synopsis Isotope Separation with the CW Hydrogen Fluoride Laser by : Stanley W. Mayer
Download or read book Isotope Separation with the CW Hydrogen Fluoride Laser written by Stanley W. Mayer and published by . This book was released on 1971 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: A CW hydrogen fluoride laser has been used successfully to separate deuterium from hydrogen by specific photocatalysis of the reaction of methanol with bromine. The strong absorption of H3COH was demonstrated for the HF laser lines P1(5), P1(6), and P1(7). No absorption by deutero-methanol of the HF beam was observed. Excitation of H2COH by the absorbed beam increased the rate of H3COH removal by reaction with bromine. Irradiation of a 1:1 H3COH:D3COD gas mixture in the presence of bromine for a period of 1 min with the 90-W CW hydrogen fluoride laser beam produced isotope enrichment to greater than 95 percent D3COD.

Book Synopsis Laser Isotope Separation and the Future of Nuclear Proliferation by : Ruben M. Serrato
Download or read book Laser Isotope Separation and the Future of Nuclear Proliferation written by Ruben M. Serrato and published by Universal-Publishers. This book was released on 2010-10 with total page 137 pages. Available in PDF, EPUB and Kindle. Book excerpt: Laser isotope separation (LIS) is an emerging technology that uses relatively small, widely-available lasers to achieve civilian or weapons grade concentration of fissile material to fuel nuclear reactions. To date only a few, limited proliferation risk analyses of LIS technology have been conducted. This paper provides a historically and technically informed update on the current state of LIS technology and it explains the high likelihood of increased global LIS adoption. The paper also explains how international rules governing nuclear energy are ill-equipped to handle such new technology. It traces the current limitations to broader issues in international relations theory, especially the incomplete accounts of the role of technology in the proliferation dynamic in the dominant neorealism and social construction of technology approaches. The paper introduces the concept of "international technology development structure," a framework for understanding how technology-related opportunities and constraints at the international system-level influence state nuclear weapons choices. The paper provides a thorough update of recent international laser innovations relevant to laser isotope separation and it explains how the spread of laser-related knowledge expands state nuclear options and influences their choices. The paper also provides a country-by-country update on LIS programs and it uses the example of Iran's laser isotope separation program to show how existing International Atomic Energy Agency efforts and export control approaches will be inadequate to addressing dual-use technologies such as LIS. It concludes by proposing a new course that links good standing in nuclear non-proliferation agreements to participation in the World Trade Organization, global conferences, and fundamental university research. Ultimately, the paper attempts to provide a comprehensive account of how emerging laser isotope separation technology presents non-proliferation challenges and it attempts to explore options for addressing this new period in technological achievement and change.
