Download or read book Synthesis and Characterization of 14 1 11 Ytterbium Manganese Antimonide Derivatives for Thermoelectric Applications written by Kurt Star and published by . This book was released on 2013 with total page 109 pages. Available in PDF, EPUB and Kindle. Book excerpt: Yb14MnSb11 is a promising thermoelectric material for high temperature applications with values of the non-dimensional figure of merit ZT peaking at 1.4 above 1200 K. Yb14MnSb11 exhibits low lattice thermal conductivity values and a p-type semimetallic behavior. This compound is a member of a large family of Zintl phases with a "14-1-11" A14MPn11 stoichiometry (Pn = As, Sb, Bi; A = Ca, La, Sr, Yb, Eu; M = Mn, Al, Cd, Ga, In, Nb, Zn). There is significant interest in investigating how substitutions on any of the atomic sites impact the band gap, lattice thermal conductivity and charge carrier concentration and mobility. High energy ball milling is shown here to be a convenient method of synthesis to prepare Yb14MnSb11 and solid solution systems derived from this compound by substitution of elements. Here compositions in the Yb14Mn1-xAlxSb11-yBiy, Yb14MnSb11-yAsy, Yb14-xCaxMnSb11, Yb14-xLaxMnSb11 and Yb14-xNaxAlSb11 systems are considered. Characterization of the synthesized compositions was done by X-ray diffraction, electron microprobe. High temperature measurements of the electrical and thermal transport properties were carried out up to 1275 K. The experimental results on solid solution samples are compared to that of pure Yb14MnSb11 samples prepared by the same synthesis technique. A single parabolic band degenerate Fermi statistical model was used to estimate various properties such as effective mass. Calculated lattice thermal conductivity in solid solutions was also compared to various models. Though some increase in ZT was calculated below 900K, none of the derivatives studied were calculated to have a averge ZT significantly higher than Yb14MnSb11.

Download or read book Frontiers in Crystalline Matter written by National Research Council and published by National Academies Press. This book was released on 2009-10-27 with total page 193 pages. Available in PDF, EPUB and Kindle. Book excerpt: For much of the past 60 years, the U.S. research community dominated the discovery of new crystalline materials and the growth of large single crystals, placing the country at the forefront of fundamental advances in condensed-matter sciences and fueling the development of many of the new technologies at the core of U.S. economic growth. The opportunities offered by future developments in this field remain as promising as the achievements of the past. However, the past 20 years have seen a substantial deterioration in the United States' capability to pursue those opportunities at a time when several European and Asian countries have significantly increased investments in developing their own capacities in these areas. This book seeks both to set out the challenges and opportunities facing those who discover new crystalline materials and grow large crystals and to chart a way for the United States to reinvigorate its efforts and thereby return to a position of leadership in this field.

Download or read book Modern Perspectives in Inorganic Crystal Chemistry written by Erwin Parthé and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 283 pages. Available in PDF, EPUB and Kindle. Book excerpt: The study of crystal structures has had an ever increasing impact on many fields of science such as physics, chemistry, biology, materials science, medicine, pharmacy, metallurgy, mineralogy and geology. Particularly, with the advent of direct methods of structure determination, the data on crystal structures are accumulating at an unbelievable pace and it becomes more and more difficult to oversee this wealth of data. A crude rationalization of the structures of organic compounds and the atom coordinations can be made with the well-known Kekule model, however, no such generally applicable model exists for the structures of inorganiC and particularly intermetallic compounds. There is a need to rationalize the inorganic crystal structures, to find better ways of describing them, of denoting the geometrical relationships between them, of elucidating the electronic factors and of explaining the bonding between the atoms with the aim of not only having a better understanding of the known structures, but also of predicting structural features of new compounds.

Download or read book Critical Mineral Resources of the United States written by K. J. Schulz and published by Geological Survey. This book was released on 2017 with total page 868 pages. Available in PDF, EPUB and Kindle. Book excerpt: As the importance and dependence of specific mineral commodities increase, so does concern about their supply. The United States is currently 100 percent reliant on foreign sources for 20 mineral commodities and imports the majority of its supply of more than 50 mineral commodities. Mineral commodities that have important uses and face potential supply disruption are critical to American economic and national security. However, a mineral commodity's importance and the nature of its supply chain can change with time; a mineral commodity that may not have been considered critical 25 years ago may be critical today, and one considered critical today may not be so in the future. The U.S. Geological Survey has produced this volume to describe a select group of mineral commodities currently critical to our economy and security. For each mineral commodity covered, the authors provide a comprehensive look at (1) the commodity's use; (2) the geology and global distribution of the mineral deposit types that account for the present and possible future supply of the commodity; (3) the current status of production, reserves, and resources in the United States and globally; and (4) environmental considerations related to the commodity's production from different types of mineral deposits. The volume describes U.S. critical mineral resources in a global context, for no country can be self-sufficient for all its mineral commodity needs, and the United States will always rely on global mineral commodity supply chains. This volume provides the scientific understanding of critical mineral resources required for informed decisionmaking by those responsible for ensuring that the United States has a secure and sustainable supply of mineral commodities.

Download or read book X ray Nanochemistry written by Ting Guo and published by Springer. This book was released on 2018-06-01 with total page 521 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the latest developments in the new research discipline of X-ray nanochemistry, which uses nanomaterials to enhance the effectiveness of X-ray irradiation. Nanomaterials now can be synthesized in such a way as to meet the demand for complex functions that enhance the X-ray effect. Innovative methods of delivering the X-rays, which can interact with those nanomaterials much more strongly than energetic electrons and gamma rays, also create new opportunities to enhance the X-ray effect. As a result, new concepts are conceived and new developments are made in the last decade, which are discussed and summarized in this book. This book will help define the discipline and encourage more students and scientists to work in this discipline. These efforts will eventually lead to formation of a full set of physical, chemical and materials principles for this new research field.
