This book was released on 1997-05-30 with total page 386 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the 1950s and 1960s, the U.S. Army conducted atmospheric dispersion tests in many American cities using fluorescent particles of zinc cadmium sulfide (ZnCdS) to develop and verify meteorological models to estimate the dispersal of aerosols. Upon learning of the tests, many citizens and some public health officials in the affected cities raised concerns about the health consequences of the tests. This book assesses the public health effects of the Army's tests, including the toxicity of ZnCdS, the toxicity of surrogate cadmium compounds, the environmental fate of ZnCdS, the extent of public exposures from the dispersion tests, and the risks of such exposures.

Book excerpt: The Pigment Compendium Dictionary is a comprehensive information source for scientists, art historians, conservators and forensic specialists. Drawn together from extensive analystical research into the physical and chemical properties of pigments, this essential reference to pigment names and synonyms describes the inter-relationship of different names and terms. The Dictionary covers the field worldwide from pre-history to the present day, from rock art to interior decoration, from ethnography to contemporary art. Drawing on hundreds of hard-to-obtain documentary sources as well as modern scientific data each term is discussed in detail, giving both its context and composition. * Comprehensive list of pigment names and synonyms * Pigments used worldwide from pre-history to the present day * Contains information from hundreds of hard-to-obtain documentary sources

Available in PDF, EPUB and Kindle. Book excerpt: This book presents and analyzes the influence of small size particles of lead, cadmium and silver sulfide on the properties of nonstoichiometric semiconductors. Important nonstoichiometry aspects in nanostructures are discussed, such as the distribution of sulfur atoms in nanofilms, a non-periodic distribution of the atomic planes in nanoparticles, interdependent changes in crystal structure of nanocrystalline material. Tuning the stoichiometry allows to obtain superionic conductivity and catalytic activity under visible light. The wavelength of the luminescence of nanoparticles changes with the size of the nanoparticles. Various methods to prepare nanostructured sulfides are described. Special attention is given to the hydrochemical bath deposition as a universal method for the synthesis of sulfides as nanofilms, stable colloidal solutions, quantum dots, isolated nanoparticles with a protective shell and heteronanostructures. The effect of nanoparticle size and nonstoichiometry on the band gap, optical and thermal properties of nanostructured sulfides is also considered. The novel applications of sulfide nanoparticles in nanoelectronics, catalysis, nanobiology and nanomedicine are sketched.

This book was released on 1997-06-14 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report begins by providing an overview of demographic modeling, including the strengths and weaknesses of this technique. Then the elements of the model are developed (e.g., workforce inflows and outflows are defined) and the data set used for estimation of the model--the Survey of Doctorate Recipients (SDR)--is described. Next, the calculation of transition rates for various life changes (e.g., retirement, changing profession) is described. At this point, the model is used to make retroactive projections that are tested against real data from the SDR. Finally, the panel presents recommendations for further work that is needed to develop the model so that it can be used to project the needs for biomedical and behavioral scientists. The report evaluates whether exposure to zinc cadmium sulfide caused adverse health effects in exposed people. This summary report was prepared to give information to concerned citizens about zinc cadmium sulfide, especially about the human health effects that might result from exposure to it. It supplements the technical document and provides answers to commonly asked questions.

This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: CdTe/CdS solar cell is one of the promising low cost high efficiency thin film solar cells. In this work, thin film CdS properties and the effect of CdS surface conditions on CdTe growth and performance of polycrystalline CdTe/CdS thin film solar cells are investigated. Thin film CdS optical, structural and chemical properties both as deposited and after CdCl 2 heat treatment are measured. CdS surface chemical state is studied by analyzing its surface chemistry after different surface treatments. Qualitative and quantitative measurements indicate sulfate and sulfite phases on thin film CdS surfaces as well as single crystal CdS, caused by oxidation in the air. The degree of CdS oxidation is highly dependent on thermal treatment ambient, temperature and time. Results indicate reduction in grain size and smoother morphology for CdTe deposited on heavily oxidized CdS compared to chemically reduced CdS surface. Solar cell open circuit voltage is much lower on cells with heavily oxidized CdS surface.
