The growth and development witnessed today in modern science, engineering, and technology owes a heavy debt to the rare, refractory, and reactive metals group, of which niobium is a member. Extractive Metallurgy of Niobium presents a vivid account of the metal through its comprehensive discussions of properties and applications, resources and resource processing, chemical processing and compound preparation, metal extraction, and refining and consolidation. Typical flow sheets adopted in some leading niobium-producing countries for the beneficiation of various niobium sources are presented, and various chemical processes for producing pure forms of niobium intermediates such as chloride, fluoride, and oxide are discussed. The book also explains how to liberate the metal from its intermediates and describes the physico-chemical principles involved. It is an excellent reference for chemical metallurgists, hydrometallurgists, extraction and process metallurgists, and minerals processors. It is also valuable to a wide variety of scientists, engineers, technologists, and students interested in the topic.

Investigations into how technologies became peculiar forms of politics in an expanded geography of the Cold War. The Cold War was not simply a duel of superpowers. It took place not just in Washington and Moscow but also in the social and political arenas of geographically far-flung countries emerging from colonial rule. Moreover, Cold War tensions were manifest not only in global political disputes but also in struggles over technology. Technological systems and expertise offered a powerful way to shape countries politically, economically, socially, and culturally. Entangled Geographies explores how Cold War politics, imperialism, and postcolonial nation building became entangled in technologies and considers the legacies of those entanglements for today's globalized world. The essays address such topics as the islands and atolls taken over for military and technological purposes by the supposedly non-imperial United States, apartheid-era South Africa's efforts to achieve international legitimacy as a nuclear nation, international technical assistance and Cold War politics, the Saudi irrigation system that spurred a Shi'i rebellion, and the momentary technopolitics of emergency as practiced by Medecins sans Frontières. The contributors to Entangled Geographies offer insights from the anthropology and history of development, from diplomatic history, and from science and technology studies. The book represents a unique synthesis of these three disciplines, providing new perspectives on the global Cold War.

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.

In order to use rare earths successfully in various applications, a good understanding of the chemistry of these elements is of paramount importance. Nearly three to four decades have passed since titles such as The Rare Earths edited by F.H. Spedding and A.H. Daane, The chemistry of the Rare Earth Elements by N.E. Topp and Complexes of the Rare Earths by S.P. Sinha were published. There have been many international conferences and symposia on rare earths, as well as the series of volumes entitled Handbook of Physics and Chemistry of Rare Earths edited by K.A. Gschneidner and L. Eyring. Thus, there is a need for a new title covering modern aspects of rare earth complexes along with the applications. The present title consists of twelve chapters. 1. Introduction2. General aspects3. Stability of complexes4. Lanthanide complexes5. Structural chemistry of lanthanide compounds6. Organometallic complexes7. Kinetics and mechanisms of rare earths complexation8. Spectroscopy of lanthanide complexes9. Photoelectron spectroscopy of rare earths10. Lanthanide NMR shift reagents11. Environmental ecological biological aspects12. Applications The authors studied in schools headed by pioneers in rare earth chemistry, have a combined experience of one hundred and fifty years in inorganic chemistry, rare earth complex chemistry, nuclear and radiochemistry of rare earths and supramolecular chemistry. The present monograph is a product of this rich experience.
