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.
Mounting Rareness takes a look at seven characteristics of growing Christians that will enable your journey of faith. I chose these two words: mounting and rareness, because we are on a faith journey that will lead us higher and higher - much as mounting the summit of a mountain. Rareness was chosen because these characteristics are rare, very rare indeed, in the current climate of Christianity - more like churchianity. Even though the times I am writing in seems to have a high religious and spiritual fervor, much seems to be based on me, my and mine instead of God the Father, Son and Holy Spirit. It is my desire to have you grow in your spiritual walk with God the Heavenly Father as revealed in the Holy Bible, which I believe is inerrant, inspired, and infallible. I believe God's Holy Word reveals the nature and character along with the great love and desire of God Almighty as He reveals Himself to you as you seek meaning and purpose in your life. Mounting Rareness has grown out of my own spiritual journey and the journeys of others around me. As you read this call to greater, may your life be filled with a MOUNTING RARENESS among so many that chooses to live at the bottom of the hill with only a longing for more.
This book provides a solid overview of the important metallurgical concepts related to the microstructures of irons and steels, and it provides detailed guidelines for the proper metallographic techniques used to reveal, capture, and understand microstructures. This book provides clearly written explanations of important concepts, and step-by-step instructions for equipment selection and use, microscopy techniques, specimen preparation, and etching. Dozens of concise and helpful 'metallographic tips' are included in the chapters on laboratory practices and specimen preparation. The book features over 500 representative microstructures, with discussions of how the structures can be altered by heat treatment and other means. A handy index to these images is provided, so the book can also be used as an atlas of iron and steel microstructures. Contents include: Introduction to steels and cast irons; Origin of microstructure; Alteration of microstructure; The metallographer and the metallographic laboratory; The metallurgical microscope; The expanded metallographic laboratory; Metallographic specimen preparation; The art of revealing microstructure; Appendices; Index.
