This book was released on 2005-11-21 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: Through innovative design, creation, processing, use, and disposal of substances, the chemical industry plays a major role in advancing applications to support sustainability in a way that will allow humanity to meet current environmental, economic, and societal needs without compromising the progress and success of future generations. Based on a workshop held in February 2005 that brought together a broad cross section of disciplines and organizations in the chemical industry, this report identifies a set of overarching Grand Challenges for Sustainability research in chemistry and chemical engineering to assist the chemical industry in defining a sustainability agenda. These Grand Challenges include life cycle analysis, renewable chemical feedstocks, and education, among others.

Download or read book Polymers and Multicomponent Polymeric Systems written by Jose James and published by CRC Press. This book was released on 2019-12-06 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, multicomponent polymers have generated much interest due to their excellent properties, unique morphology and high-end applications. Book focusses on thermal, thermo-mechanical and dielectric analysis of polymers and multicomponent polymeric systems like blends, interpenetrating polymeric networks (IPNs), gels, polymer composites, nanocomposites. Through these analyses, it provides an insight into the stability of polymer systems as a function of time, processing and usage. Aimed at polymer chemists, physicists and engineers, it also covers ASTM /ISO and other standards of various measurement techniques for systematic analysis in materials science.

This book was released on 2018-07-13 with total page 50 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this study was on the autoxidation kinetics of deposit precursor formation in jet fuels. The objectives were: (1) to demonstrate that laser-induced fluorescence is a viable kinetic tool for measuring rates of deposit precursor formation in jet fuels; (2) to determine global rate expressions for the formation of thermal deposit precursors in jet fuels; and (3) to better understand the chemical mechanism of thermal stability. The fuels were isothermally stressed in small glass ampules in the 120 to 180 C range. Concentrations of deposit precursor, hydroperoxide and oxygen consumption were measured over time in the thermally stressed fuels. Deposit precursors were measured using laser-induced fluorescence (LIF), hydroperoxides using a spectrophotometric technique, and oxygen consumption by the pressure loss in the ampule. The expressions, I.P. = 1.278 x 10(exp -11)exp(28,517.9/RT) and R(sub dp) = 2.382 x 10(exp 17)exp(-34,369.2/RT) for the induction period, I.P. and rate of deposit precursor formation R(sub dp), were determined for Jet A fuel. The results of the study support a new theory of deposit formation in jet fuels, which suggest that acid catalyzed ionic reactions compete with free radical reactions to form deposit precursors. The results indicate that deposit precursors form only when aromatics are present in the fuel. Traces of sulfur reduce the rate of autoxidation but increase the yield of deposit precursor. Free radical chemistry is responsible for hydroperoxide formation and the oxidation of sulfur compounds to sulfonic acids. Phenols are then formed by the acid catalyzed decomposition of benzylic hydroperoxides, and deposit precursors are produced by the reaction of phenols with aldehydes, which forms a polymer similar to Bakelite. Deposit precursors appear to have a phenolic resin-like structure because the LIF spectra of the deposit precursors were similar to that of phenolic resin dissolved in TAM. Naegeli, David W.
