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.
This book is compiled of 26 old, rare and forgotten Fairy Tales and stories taken from books in Abela Publishing's series "Folk-Lore, Fairy Tales, Myths and Legends from Around the World". A series created to raise funds for the education of underprivileged individuals. Keeping true to our vision, the intent behind this compendium is to raise funds for UK's Children in Need Appeal of 2009. GBP1.60 from the sale of every book will be donated. In buying this book you will be giving in more than one way. Once to the Children in Need appeal and again, to yourself, as you read and enjoy stories not read for many a year. But should you perchance happen to read these stories to your children, nieces and nephews or grand-children, you will be giving yet again. The words 'Fairy Tales' must accordingly be taken to include tales in which something 'fairy', something extraordinary occurs -- fairies, giants, dwarfs, speaking animals. One cannot imagine a child saying, 'Tell me a folk-tale', or 'Another nursery tale, please, grandma'. It must also be taken to cover tales in which something magical happens. Mostly it is the comical stupidity of some of the actors, as is so common in moral tales. So take some time out and travel back to a period before television, or even radio for that matter, when families would gather around a crackling and spitting hearth and granddad or grandma or an uncle or aunt would delight and captivate their audience with stories passed on to them from their mothers, fathers and grandparents.
Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry.
