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 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.
"I don't suppose you have a friend who is a warthog. You probably don't have a friend who is a professional detective, either. So it's very unlikely that you have a friend who's both. But I do."So begins the adventures of Nixk Sayga and his friend Bill, a warthog detective, in Full Metal Trench Coat, the first book in the new Bill the Warthog Mysteries series. As Bill fights kid's "crimes," such as investigating celebrity soccer shoes and broken skateboard helmets, he also teaches Nick and his friends about the Armour of God. Kids will love trying to figure out each chapter's mystery as they enjoy the zany antics of Bill, Nick and their friends. And they will laugh at Bill's crazy attempts to fit in with kids, even putting tennis balls on his tusks so he can join the soccer team without risk of injuring the palyers! Bill the Warthog Mysteries: Full Metal Trench Coat will bring laughter and learning to preteens, and kids of all ages!
