Description : This book examines the current state of the art, new challenges, opportunities, and applications in the area of polymer nanocomposites. Special attention has been paid to the processing-morphology-structure-property relationship of the system. Various unresolved issues and new challenges in the field of polymer nanocompostes are discussed. The influence of preparation techniques (processing) on the generation of morphologies and the dependence of these morphologies on the properties of the system are treated in detail. This book also illustrates different techniques used for the characterization of polymer nanocomposites. The handpicked selection of topics and expert contributors across the globe make this survey an outstanding resource reference for anyone involved in the field of polymer nanocompostes for advanced technologies.
Description : Filling the gap for a reference dedicated to the characterization of polymer blends and their micro and nano morphologies, this book provides comprehensive, systematic coverage in a one-stop, two-volume resource for all those working in the field. Leading researchers from industry and academia, as well as from government and private research institutions around the world summarize recent technical advances in chapters devoted to their individual contributions. In so doing, they examine a wide range of modern characterization techniques, from microscopy and spectroscopy to diffraction, thermal analysis, rheology, mechanical measurements and chromatography. These methods are compared with each other to assist in determining the best solution for both fundamental and applied problems, paying attention to the characterization of nanoscale miscibility and interfaces, both in blends involving copolymers and in immiscible blends. The thermodynamics, miscibility, phase separation, morphology and interfaces in polymer blends are also discussed in light of new insights involving the nanoscopic scale. Finally, the authors detail the processing-morphology-property relationships of polymer blends, as well as the influence of processing on the generation of micro and nano morphologies, and the dependence of these morphologies on the properties of blends. Hot topics such as compatibilization through nanoparticles, miscibility of new biopolymers and nanoscale investigations of interfaces in blends are also addressed. With its application-oriented approach, handpicked selection of topics and expert contributors, this is an outstanding survey for anyone involved in the field of polymer blends for advanced technologies.
Description : The most popular class of dark matter candidates is the class of weakly-interacting massive particles (WIMPs). The Fermi Large Area Telescope has the possibility of indirectly detecting WIMPs by the flux from their annihilation/decay products. When a WIMP annihilates or decays directly into a photon gamma and another particle Y the photons are monochromatic. Detection of the resulting spectral line(s) would provide convincing evidence for particulate dark matter and could provide the WIMP mass. In the case of no detection, knowledge of the dark matter distribution can be used to place limits on the annihilation cross section and lifetime for the WIMP(s) to Y-gamma channel. We present the spectrum from 4.8 to 264 GeV and spectral line flux upper limits, obtained from a subset of this spectrum, from 7 to 200 GeV. The spatial region of the dataset covers a large portion of the sky, the high latitudes plus the Galactic Center. We report upper limits on the WIMP cross sections for annihilation to gamma-gamma and Z-gamma and lower limits on the WIMP lifetime for decay to gamma-neutrino. We discuss the implications of the spectrum and line flux limits for several dark matter models with optimistic branching ratios for photon channels.
Description : Ghetto, forced labor camp, concentration camp: All of the elements of the National Socialists' policies of annihilation were to be found in Riga. This first analysis of the Riga ghetto and the nearby camps of Salaspils and Jungfernhof addresses all aspects of German occupation policy during the Second World War. Drawing upon a broad array of sources that includes previously inaccessible Soviet archives, postwar criminal investigations, and trial records of alleged perpetrators, and the records of the Society of Survivors of the Riga Ghetto, the authors have produced an in-depth study of the Riga ghetto that never loses sight of the Latvian capital's place within the overall design of Nazi policy and the all-of-Europe dimension of the Holocaust.
Description : Describes the 12th expedition to “Area X,” a region cut off from the continent for decades, by a group of intrepid women scientists who try to ignore the high mortality rates of those on the previous 11 missions. Original. 75,000 first printing.
