Download or read book Helium Three written by Roland Dobbs and published by . This book was released on 2000 with total page 1088 pages. Available in PDF, EPUB and Kindle. Book excerpt: The condensed phases of helium three provide an exciting laboratory for many fundamental questions in condensed matter physics. Due to its light mass and weak interatomic potential, the condensed phases of helium display quantum effects more dramatically than any other atomic system. Intuitionbased on classical experience is often misleading in these phases: the solid phase for instance is less ordered at low temperature than the liquid phase. The present book is unique in covering all the low temperature properties of helium three as liquid, superfluid, and solid. It provides anintroduction to the extensive literature on helium three from the point of view of an experimentalist, and includes the analogy of its properties with the cosmological 'big bang'. Graduate students, researchers, and professionals in condensed matter physics and low temperature physics will findthis the standard reference work for the decade to come.

Book Synopsis The Impact of Selling the Federal Helium Reserve by : National Research Council
Download or read book The Impact of Selling the Federal Helium Reserve written by National Research Council and published by National Academies Press. This book was released on 2000-06-18 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Helium Privatization Act of 1996 (P.L. 104-273) directs the Department of the Interior to begin liquidating the U.S. Federal Helium Reserve by 2005 in a manner consistent with "minimum market disruption" and at a price given by a formula specified in the act. It also mandates that the Department of the Interior "enter into appropriate arrangements with the National Academy of Sciences to study and report on whether such disposal of helium reserves will have a substantial adverse effect on U.S. scientific, technical, biomedical, or national security interests." This report is the product of that mandate. To provide context, the committee has examined the helium market and the helium industry as a whole to determine how helium users would be affected under various scenarios for selling the reserve within the act's constraints. The Federal Helium Reserve, the Bush Dome reservoir, and the Cliffside facility are mentioned throughout this report. It is important to recognize that they are distinct entities. The Federal Helium Reserve is federally owned crude helium gas that currently resides in the Bush Dome reservoir. The Cliffside facility includes the storage facility on the Bush Dome reservoir and the associated buildings pipeline.
Download or read book Crescent written by Homer Hickam and published by Thomas Nelson. This book was released on 2013-06-04 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: She was born to kill, born to die. Crescent is a crowhopper—a genetically modified mercenary programmed for ruthless warfare. When she’s taken prisoner by Crater Trueblood instead of being killed in battle, she thinks it’s a disaster. Crater is weary of war. He’s a miner, not a soldier. He’d rather be mining Helium-3 than battling the infernal crowhoppers. But after he captures Crescent and brings her to Moontown, he’s surprised how much he enjoys her company. When she’s falsely accused of murder, he becomes an outlaw to help her escape. The unlikely pair escapes into the “big suck” and wind up trekking with a caravan of mining pioneers toward a lunar ghost town called Endless Dust. To survive, they must do more than navigate the beautiful, desolate moonscape and battle a persistent band of crowhoppers sent to capture or kill them. They must decide what—and who—is truly worth fighting for. “Expertly blending space opera and hard sci-fi, romance, and even mystery . . . this is fast-paced, packed with intriguing ideas . . .” —Peter Gutierrez, Booklist Review “Classic Golden Age science fiction high-adventure. It brought back memories of reading Asimov . . . that same sense of wonder. I absolutely loved it.” —Michael Scott, New York Times Best-selling Author, The Secrets of the Immortal Nicholas Flamel series
Book Synopsis Exotic Properties of Superfluid Helium 3 by : G E Volovik
Download or read book Exotic Properties of Superfluid Helium 3 written by G E Volovik and published by World Scientific. This book was released on 1992-03-31 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses the unique properties of superfluid phases of 3He, the condensed matter with the outmost broken symmetry, which combine in a surprising way the properties of ordered magnets, liquid crystals and superfluids. The complicated vacuum state of these phases with a large number of fermionic and bosonic quasiparticles and topological objects remains the vacuum in modern quantum field theories. Some of the objects and physical phenomena in 3He have strong analogy with the neutrino, W-bosons, weak interactions, gravity, chiral anomaly, Quantum Hall Effect and fractional statistics. As an example of topological objects, the quantized vortices in 3He phases are discussed in detail, including singular and continuous vortices, half-quantum vortices, broken symmetry in the vortex core and phase transitions between the vortex states with different symmetry and topology.

Book Synopsis Tritium and Helium-3 in Metals by : Rainer Lässer
Download or read book Tritium and Helium-3 in Metals written by Rainer Lässer and published by Springer Science & Business Media. This book was released on 2013-03-13 with total page 167 pages. Available in PDF, EPUB and Kindle. Book excerpt: Hydrogen can behave as an alkaline metal or a halogen and can react with nearly all elements of the periodic table. This explains the large number of metal hydrides. Since T. Graham's first observation of the absorption of hydrogen in palladium in 1866 the behaviour of hydrogen in metals has been studied very extensively. The interest was motivated by the possible application of metal-hydrogen systems in new technologies (e.g., moderator material in nuclear fission reactors, reversible storage material for thermal energy and large amounts of hydrogen) and by the fact that metal hydrides show very exciting physical properties (e.g., superconductivity, quantum diffusion, order-disorder transitions, phase diagrams, etc.). Many of these properties have been determined for the stable hydrogen isotopes Hand D in various metals. In comparison, very little is known about the behaviour of the ra dioactive isotope tritium in metals. This book is a first attempt to summarize part of the knowledge of tritium gained in the last few years. In addition to the task of presenting the properties of tritium in metals, I have tried to compare these data with those of protium and deuterium. Furthermore, helium-3 is connected inse parably with tritium via the tritium decay. Therefore one chapter of this book is solely devoted to the curious properties of helium in metals caused mainly by its negligible solubility.

Book Synopsis Solid Helium Three by : Roland Dobbs
Download or read book Solid Helium Three written by Roland Dobbs and published by . This book was released on 1994 with total page 232 pages. Available in PDF, EPUB and Kindle. Book excerpt: The discovery of the astonishing properties of helium three crystals has been one of the hottest topics in low temperature physics over the last two decades. This book provides the first complete account of those properties, including descriptions and interpretations of critical experimental measurements. Beginning with the phase diagram and thermal properties of this uniquely quantum crystal, the author skillfully introduces current theories of solid helium and compares their predictions with measurements of the ground state, elastic and thermal properties, and phonon spectra. The extraordinary magnetic properties are described and discussed in chapters devoted to the paramagnetism, antiferromagnetism, and ferromagnetism of the different phases of solid helium. The text concludes with chapters on crystal growth and defects, and sections on monolayers, bilayers, and multilayers grown on a variety of substrates. Students and researchers in condensed matter physics, physical chemistry, and applied mathematics will welcome this exceptional new book.

Book Synopsis Selling the Nation's Helium Reserve by : National Research Council
Download or read book Selling the Nation's Helium Reserve written by National Research Council and published by National Academies Press. This book was released on 2010-06-30 with total page 157 pages. Available in PDF, EPUB and Kindle. Book excerpt: Helium has long been the subject of public policy deliberation and management, largely because of its many strategic uses and its unusual source-it is a derived product of natural gas and its market has several anomalous characteristics. Shortly after sources of helium were discovered at the beginning of the last century, the U.S. government recognized helium's potential importance to the nation's interests and placed its production and availability under strict governmental control. In the 1960s, helium's strategic value in cold war efforts was reflected in policies that resulted in the accumulation of a large reserve of helium owned by the federal government. The latest manifestation of public policy is expressed in the Helium Privatization Act of 1996 (1996 12 Act), which directs that substantially all of the helium accumulated as a result of those earlier policies be sold off by 2015 at prices sufficient to repay the federal government for its outlays associated with the helium program. The present volume assesses whether the interests of the United States have been well served by the 1996 Act and, in particular, whether selling off the helium reserve has had any adverse effect on U.S. scientific, technical, biomedical, and national security users of helium.

Book Synopsis Helium by : Wheeler M. "Bo" Sears, Jr.
Download or read book Helium written by Wheeler M. "Bo" Sears, Jr. and published by Springer. This book was released on 2015-02-19 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject of the book is helium, the element, and its use in myriad applications including MRI machines, particle accelerators, space telescopes, and of course balloons and blimps. It was at the birth of our Universe, or the Big Bang, where the majority of cosmic helium was created; and stellar helium production continues. Although helium is the second most abundant element in the Universe, it is actually quite rare here on Earth and only exists because of radioactive elements deep within the Earth. This book includes a detailed history of the discovery of helium, of the commercial industry built around it, how the helium we actually encounter is produced within the Earth, and the state of the helium industry today. The gas that most people associate with birthday party balloons is running out. “Who cares?” you might ask. Well, without helium, MRI machines could not function, rockets could not go into space, particle accelerators such as those used by CERN could not operate, fiber optic cables would not exist, and semiconductor chips could not be made...the list goes on and on.
Book Synopsis Studying Complex Surface Dynamical Systems Using Helium-3 Spin-Echo Spectroscopy by : Barbara A. J. Lechner
Download or read book Studying Complex Surface Dynamical Systems Using Helium-3 Spin-Echo Spectroscopy written by Barbara A. J. Lechner and published by Springer Science & Business. This book was released on 2014-04-23 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: Chemical reactions and growth processes on surfaces depend on the diffusion and re-orientation of the adsorbate molecules. A fundamental understanding of the forces guiding surface motion is thus of utmost importance for the advancement of many fields of science and technology. To date, our understanding of the principles underlying surface dynamics remains extremely limited, due to the difficulties involved in measuring these processes experimentally. The helium-3 spin-echo (HeSE) technique is uniquely capable of probing such surface dynamical phenomena. The present thesis extends the field of application of HeSE from atomic and small molecular systems to more complex systems. Improvements to the supersonic helium beam source, a key component of the spectrometer, as well as a detailed investigation of a range of five-membered aromatic adsorbate species are presented. The thesis provides a comprehensive description of many aspects of the HeSE method - instrumentation, measurement and data analysis - and as such offers a valuable introduction for newcomers to the field.
