As the most important liquid in our life and one of the most abundant molecules in the universe, water is the least understood substance with a very rich phase diagram (at least 18 crystalline forms and two liquids) and more that 60 dynamical/thermodynamic anomalies whose origins are still under debate. Properties of Water from Numerical and Experimental Perspectives gathers together leading scientists and experts in the field of water. By merging the theoretical/computational point of view with experimental approaches, it presents a state-of-the-art description of the properties of water, enlightening the source of the anomalies of water and describing how such anomalies actively affect the functioning of biological substances.
In recent times, physicists have come to appreciate information’s central role in the universe’s grand plan. That and the fact that an explicit understanding of the informational relationships involved may well be key to unlocking many of the universe’s deepest secrets. That makes the birth of both Computer and Information Science not only essential to the explosion of modern technological success, but also to our understanding of reality itself. In recognizing that, what unfolds is a story not only about Alan Turing and his pioneering colleagues, but also great thinkers like Albert Einstein, Michael Faraday, Ludwig Wittgenstein and others. It therefore pulls in much of modern history ...
Due to recent advancements in the development of numerical algorithms and computational hardware, computer simulations of biological membranes, often requiring use of substantial computational resources, are now reaching a mature stage. Since molecular processes in membranes occur on a multitude of spatial and time scales, molecular simulations of membranes can also serve as a testing ground for use of multi-scale simulation techniques. This book addresses some of the important issues related to understanding properties and behavior of model biological membranes and it Shows how simulations improve our understanding of biological membranes and makes connections with experimental results.

This book discusses the interaction of strongly basic anion exchangers with some metal cations. These polymers are a high tonnage production of the chemical industry, and are widely used in various chemical and technical operations, particularly in the treatment of water at thermal and atomic power stations. Their interaction with metal cations, especially with iron, an unpredictable and uncontrollable process, leads to their intoxication and rapid exhaustion. However, if the interaction of these polymers with cations is controlled, then in the polymer phase, ultra-fine particles of the compounds are formed, which radically change their physical and chemical properties. These composites become selective sorbents and catalysts with good hydro and aerodynamic properties to carry out processes in flow, an important factor in technology. This is demonstrated by patents on water purification from chromates, nitrate/nitrite, sulphides and air purification from iodine and hydrogen sulfide. The book also shows, for the first time, that cations Fe3+, Cr3+, Al3+, Ga3+, In3+, lanthanide (III) in the phase of strongly basic anion exchangers form compounds of the jarosite mineral type.
De 29 de setembro a 6 de outubro de 2008, o jornalista Gustavo Queiroz tornou-se um caminhoneiro para reportar, in loco, a vida desses profissionais que “carregam o Brasil nas costas, não deixam faltar produtos nas gôndolas e prateleiras das lojas”. A vida dos caminhoneiros é esperar, e para produzir este livro Gustavo Queiroz esperou com eles, com rara sensibilidade, disposição e o apoio logístico da IVECO, fabricante do caminhão conduzido por Gilson Furlanetto, ao lado de quem o jornalista viajou.
This volume contains invited and contributed papers presented at the conference on ‘Microscopy of Semiconducting Materials’ held at the University of Cambridge on 2-5 April 2007. The event was organised under the auspices of the Electron Microscopy and Analysis Group of the Institute of Physics, the Royal Microscopical Society and the Materials Research Society. This international conference was the fifteenth in the series that focuses on the most recent world-wide advances in semiconductor studies carried out by all forms of microscopy and it attracted delegates from more than 20 countries. With the relentless evolution of advanced electronic devices into ever smaller nanoscale structur...
