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.
A follow-up to O'Hara's steamy and provocative book Autopornography: A Memoir of Life in the Lust Lane, Rarely Pure and Never Simple: Selected Essays of Scott O'Hara shares with you more intimate stories from former porn star Scott O'Hara. You'll gain an even deeper sense of the man behind the "Biggest Dick in San Francisco" and come to understand his take on porn, sex, life, and loss. Discussing his ventures as a writer, playwright, and editor of the popular but short-lived journal Steam, Rarely Pure and Never Simple includes poems and stories by O'Hara that express his opinions and feelings about monogamy, safe sex, male beauty, morality, social politics, and "being queer." O'Hara also relates his childhood experiences to his adult life and uses many examples to link the past to his actions and thoughts concerning his sexuality.Bold, personal, and honest, Rarely Pure and Never Simple gives you an inside look into the life of this controversial author, who died in February 1998 of AIDS-related complications. O'Hara challenges the "norms" of society as he discloses intimate thoughts and details about his sex life and fantasies that are guaranteed to arouse your . . . curiosity.
Metals in Surface Waters presents state-of-the-art research and applications on the full range of subjects, including toxicity to aquatic organisms as well as humans with an emphasis on metals speciation. The book explores metals contamination of surface waters from several different disciplines, such as analytical chemistry, aquatic chemistry and toxicology, environmental engineering, and oceanography.
