This book was released on 2012-12-06 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: During its short 20 year history High Performance Liquid Chro matography (HPLC) has won itself a firm place amongst the instrumental methods of analysis. HPLC has caused a revolution in biological and pharmaceutical chemistry. Approximately two thirds of the publications on HPLC are concerned with problems from this area of life science. Biotechnology, where it is necessary to isolate substances from complicated mixtures, is likely to give further impetus to the dissemination of modern liquid chromatog raphy in columns, particularly on the preparative scale. This book presents, by means of examples, the application of HPLC to various fields, as well as fundamental discussions of chromatographic methods. The quality of the analytical result is decisively dependent on the qualities of the equipment employed (by Colin, Guiochon, and Martin). Especially the demands are discussed that are placed on the components of the instrument including those for data acquisition and processing. The section on "quantitative analy sis" (by ABhauer, Ullner) covers besides the principles also the problems of ensuring the quality of the data in detail. The basic problems arising by enlarging the sample size to preparative di mensions and the requirements put on the aparatus are discussed in the section on "preparative applications" (by Wehrli).

Available in PDF, EPUB and Kindle. Book excerpt: Recent years have seen a growing interest in the application of chalcogenide nanoparticles (NPs), e.g. Se, Te, CdSe and CdTe NPs, in various industrial sectors including energy, petroleum refining and in the field of biology and medicine. Moreover, due to the high toxicity of chalcogen oxyanions, their release into the environment is of great concern. Thus, emphasis was given in this study on the development of a novel microbial synthesis process of chalcogenide NPs by combining biological treatment of Se/Te containing wastewaters with biorecovery in the form of Se NPs, Te NPs and CdSe NPs. Enrichment of Se-oxyanion reducing microorganisms was carried out to simultaneously remove selenite (Se(IV)) and cadmium (Cd(II)) from wastewaters by combining bioremediation of toxic Se-rich wastewater with the biorecovery of Se as CdSe NPs. The results showed compositional changes in the extracellular polymeric substances (EPS) matrix of the anaerobic granular sludge upon exposure to Cd(II) and Se(IV) and identified the roles of EPS fractions in the biogenesis of CdSe NPs. Besides, it was found that the EPS on the surface of the biogenic Se NPs play a major role in lowering the bioavailability and toxicity of biogenic Se(0) compared to chemogenic Se(0) NPs. An upflow anaerobic sludge blanket (UASB) reactor was used for the first time to continuously remove tellurite from wastewater and recover biogenic Te(0).

Available in PDF, EPUB and Kindle. Book excerpt: This book explores oxygen-free chalcogenide glasses, the only commercial transparent vitreous materials used for long-wave infrared radiation. The chalcogenides have been the subject of study around the world for many years, and continue to be an important area of research and development in infrared optics. Written by a renowned glass specialist with extensive experience working with chalcogenide glasses, Glasses for Infrared Optics includes discussions of: Chalcogenide glasses - a unique class of vitreous substances Optical properties of chalcogenide glasses Elaboration of commercial glasses Technological basics for manufacturing optical chalcogenide glasses The material presented in Glasses for Infrared Optics is based on research performed at the Vavilov State Optical Institute in Russia. This is the first and only work that reviews every aspect of chalcogenide glasses. The scope of this comprehensive book is unique, and the major portion of this work has never been published before in English.

Download or read book Chalcogenadiazoles written by Zory Vlad Todres and published by CRC Press. This book was released on 2011-08-24 with total page 313 pages. Available in PDF, EPUB and Kindle. Book excerpt: A timely and authoritative treatise on the chemistry and diverse applications of chalcogenadiazoles — the five-membered rings containing two carbons, two nitrogens, and one chalcogen (an member of group 16, the oxygen family). The number of different chalcogenadiazoles and their structural diversity make it difficult to gain a clear understanding of the subject by studying an individual system in isolation. Chalcogenadiazoles: Chemistry and Applications emphasizes general features of this class of heterocyclic compounds. It concentrates on properties of each class of chalcogenadiazoles and their cycle-fused derivatives, considering chemical reactions of functional groups only in cases when these reactions permit to characterize the heterocycles as substituents or in respect of its aromaticity. Covering an important and rapidly developing branch of heterocyclic chemistry, this book is an essential resource for students, young professionals and experienced specialists in adjacent fields who are interested in: Trends in the search for compounds with established bioactivity or use in medicine, as agrochemicals, or as reagents for environmental and biochemical analysis Differences in classes of chalcogenadiazoles with respect to their degree of aromaticity and similar general concepts helpful to the nonspecialist The effects of the chalcogen nature and the alternation manner of all atomic constituents on properties of these heterocyclic compounds Combining data from organic, biological, medicinal, materials science, and supramolecular chemistry, Chalcogenadiazoles: Chemistry and Applications is an important source of information not only for chemists in the fields of organic, inorganic, and organometallic chemistry, but also for anyone interested in the research and development of chalcogenadiazoles and related species.

Download or read book Nanolubricants written by Jean Michel Martin and published by John Wiley & Sons. This book was released on 2008-04-30 with total page 246 pages. Available in PDF, EPUB and Kindle. Book excerpt: The technology involved in lubrication by nanoparticles is a rapidly developing scientific area and one that has been watched with interest for the past ten years. Nanolubrication offers a solution to many problems associated with traditional lubricants that contain sulphur and phosphorus; and though for some time the production of nanoparticles was restricted by the technologies available, today synthesis methods have been improved to such a level that it is possible to produce large quantities relatively cheaply and efficiently. Nanolubricants develops a new concept of lubrication, based on these nanoparticles, and along with the authors’ own research it synthesises the information available on the topic of nanolubrication from existing literature and presents it in a concise form. Describes the many advantages and potential applications of nanotechnology in the tribological field. Offers a full review of the state-of-the-art as well as much original research that is yet unpublished. Includes sections on boundary lubrication by colloïdal systems, nanolubricants made of metal dichalcogenides, carbon-based nanolubricants, overbased detergent salts, nanolubricants made of metals and boron-based solid nanolubricants and lubrication additives. Authored by highly regarded experts in the field with contributions from leading international academics. Nanolubricants will appeal to postgraduate students, academics and researchers in mechanical engineering, chemical engineering and materials science. It should also be of interest to practising engineers with petroleum companies and mechanical manufacturers.
