The story of one citizen's fight to preserve a US stake in the future of clean energy and the elements essential to high tech industries and national defense. American technological prowess used to be unrivaled. But because of globalization, and with the blessing of the U.S. government, once proprietary materials, components and technologies are increasingly commercialized outside the U.S. Nowhere is this more dangerous than in China's monopoly of rare earth elements-materials that are essential for nearly all modern consumer goods, gadgets and weapons systems. Jim Kennedy is a retired securities portfolio manager who bought a bankrupt mining operation. The mine was rich in rare earth elements, but he soon discovered that China owned the entire global supply and manufacturing chain. Worse, no one in the federal government cared. Dismayed by this discovery, Jim made a plan to restore America's rare earth industry. His plan also allowed technology companies to manufacture rare earth dependent technologies in the United States again and develop safe, clean nuclear energy. For years, Jim lobbied Congress, the Pentagon, the White House Office of Science and Technology, and traveled the globe to gain support. Exhausted, down hundreds of thousands of dollars, and with his wife at her wits' end, at the start of 2017, Jim sat on the edge of victory, held his breath and bet it all that his government would finally do the right thing. Like Beth Macy's Factory Man, this is the story of one man's efforts to stem the dehumanizing tide of globalization and Washington's reckless inaction. Jim's is a fight we need to join.

All metallic materials are prepared from the liquid state as their parent phase. Solidification is therefore one of the most important phase transformation in daily human life. Solidification is the transition from liquid to solid state of matter. The conditions under which material is transformed determines the physical and chemical properties of the as-solidified body. The processes involved, like nucleation and crystal growth, are governed by heat and mass transport. Convection and undercooling provide additional processing parameters to tune the solidification process and to control solid material performance from the very beginning of the production chain. To develop a predictive capability for efficient materials production the processes involved in solidification have to be understood in detail. This book provides a comprehensive overview of the solidification of metallic melts processed and undercooled in a containerless manner by drop tube, electromagnetic and electrostatic levitation, and experiments in reduced gravity. The experiments are accompanied by model calculations on the influence of thermodynamic and hydrodynamic conditions that control selection of nucleation mechanisms and modify crystal growth development throughout the solidification process.
