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.
"Turkish Metal" journeys deep into the heart of the Turkish heavy metal scene, uncovering the emergence, evolution, and especially the social implications of this controversial musical genre in a Muslim society. The book applies the approach of 'thick description' in order to study social and cultural change in a Muslim society that is stricken with conflict over the, by turns, religious or secular nature of the state. "Turkish Metal" explores how Turkish metalheads, against all odds, manage to successfully claim public spaces of their own, thereby transforming the public face of the city. The book raises the question of how and why the young dare to rebel against the prevalent social and moral restrictions in Turkish society; and it examines whether they succeed in asserting their individual freedom in a society that is still well-known for sanctioning any kind of behaviour deviating from the norm. Above all, the book investigates the Turkish metal scene's potential for contesting Islamic concepts of morality, its relevance within the field of female emancipation, and its capacity to foster social relations that cut across national, religious and ethnic boundaries.
