This collection presents the papers presented in the symposium on extraction of rare metals as well as rare extraction processing techniques used in metal production. Paper topics include the extraction and processing of elements like antimony, arsenic, calcium, chromium, hafnium, gold, indium, lithium, molybdenum, niobium, rare earth metals, rhenium, scandium, selenium, silver, strontium, tantalum, tellurium, tin, tungsten, vanadium, and zirconium. Rare processing techniques presented include bio leaching, molecular recognition technology, recovery of valuable components of commodity metals such as magnesium from laterite process wastes, titanium from ilmenites, and rare metals from wastes such as phosphors and LCD monitors.
Metal-semiconductor nanostructures represent an important new class of materials employed in designing advanced optoelectronic and nanophotonic devices, such as plasmonic nanolasers, plasmon-enhanced light-emitting diodes and solar cells, plasmonic emitters of single photons, and quantum devices operating in infrared and terahertz domains. The combination of surface plasmon resonances in conducting structures, providing strong concentration of an electromagnetic optical field nearby, with sharp optical resonances in semiconductors, which are highly sensitive to external electromagnetic fields, creates a platform to control light on the nanoscale. The design of the composite metal-semiconductor system imposes the consideration of both the plasmonic resonances in metal and the optical transitions in semiconductors - a key issue being their resonant interaction providing a coupling regime.
This volume deals with rare earth elements, applying basic research data on neodymium used in permanent magnets.
Metal A Treasure Hunt Dr. Frank Lally, a retired Navy podiatrist, is a family man and metal detector hobbyist. His wife is being treated for Alzheimer's disease at an expensive lifecare center. His step-daughter needs to divorce her cheating husband and move back home. His step-son is losing his job, his place to live, and he has hardly written a word of his great American novel. Frank wonders how he will keep it all together when, one day, he takes a long walk with his dogs ...
