This volume aims at bringing together the results of extensive research done during the last fifteen years on the interfacial photoelectronic properties of the inorganic layered semiconducting materials, mainly in relation to solar energy conversion. Significant contributions have been made both on the fundamental aspects of interface characteristics and on the suitability of the layered materials in photoelectrochemical (semiconductor/electrolyte junctions) and in solid state photovoltaic(Schot...

Cream Quantitative Structure -- Activity or Property Relationships (QSAR/QSPR) to explain the observed activities or properties of compounds then predict them for new compounds. SciQSAR makes this job easy with its use of 2D and 3D molecular descriptors and fast statistical routines. It's a timesaving software tool for researchers working in materials or life sciences.

Aline Leon In the last years, public attention was increasingly shifted by the media and world governmentsto the conceptsof saving energy,reducingpollution,protectingthe - vironment, and developing long-term energy supply solutions. In parallel, research funding relating to alternative fuels and energy carriers is increasing on both - tional and international levels. Why has future energy supply become such a matter of concern? The reasons are the problems created by the world's current energy...

Das Wissensgebiet der Physikalischen Chemie hat sich so stark ausgeweitet und vertieft, daB man berechtigterweise die Frage stellen kann, ob man heute ein Buch vom Umfang des hier vorliegenden iiberhaupt noch schreiben diirfe. leh habe diese Frage mit meinem Mitarbeiter Herm Dr. Gerhard Greiner, dem an dieser Stelle flir seine kritische Unterstiitzung herzlich gedankt sei, lange diskutiert mit dem Ergebnis, daB man der Physikalischen Chemie wissen- schaftlich nur beschrankt gerecht werden k6nne,...

This book reviews the most significant advances in concepts, methods, and applications of quantum systems in a broad variety of problems in modern chemistry, physics, and biology. In particular, it discusses atomic, molecular, and solid structure, dynamics and spectroscopy, relativistic and correlation effects in quantum chemistry, topics of computational chemistry, physics and biology, as well as applications of theoretical chemistry and physics in advanced molecular and nano-materials and bioc...

There can be few elements with a biochemistry as coherent as that of sulfur. This important element is crucial to myriad aspects of metabo lism, catalysis, and structure. The plurality of functions in which sulfur is involved derives squarely from the numerous oxidation states in which it may exist, some having great stability, some being capable of ready redox interconversions, and yet others having great instability. As a result, the flux of sulfur from the geosphere through the various kingd...

This volume documents the proceedings of the Symposium on Polymers in Information Storage Technology held as a part of the American Chemical Society meeting in Los Angeles, September 25-30, 1988. It should be recorded here that this symposium was cosponsored by the Division of Polymeric Materials: Science and Engineering, and the Division of Polymer Chemistry. Polymers are used for a variety of purposes in both optical and magnetic information storage technologies. For example, polymers find app...

The declared objective of this book is to provide an introductory review of the various theoretical and practical aspects of adsorption by powders and porous solids with particular reference to materials of technological importance. The primary aim is to meet the needs of students and non-specialists, who are new to surface science or who wish to use the advanced techniques now available for the determination of surface area, pore size and surface characterization. In addition, a critical accoun...

This book presents the fundamental principles of thermodynamics for geosciences, based on the author's own courses over a number of years. Many examples help to understand how mineralogical problems can be solved by applying thermodynamic principles.

With the development of science and technology,more and more complex materials such as porous materials, ion liquid, liquid crystals, thin ?lms and colloids etc. are being developed in laboratories. However, it is dif?cult to prepare these advanced materials and use them on a large scale without some experience. Therefore, mo- cular thermodynamics, a method that laid emphasis on correlating and interpreting the thermodynamic properties of a variety of ?uids in the past, has been recently employe...

The design and the realisation of well defined polymer architectures has become an important goal in macromolecular science. The prerequisite for achieving this goal is the availability of controlled polymerisation reactions. Living anionic polymerisation was the first reaction fulfilling these requirements. Cationic polymerisation only came into play when it was realised that it was possible to create an equilibrium between active and dormant species with the fraction of the dormant species bei...

While there are many excellent textbooks and reference books covering the chemistry, physics, rheology, processing, and characterization of polymers, this textbook is the first treatment in one place of the modeling and simulation of polymerization reactions. This is the very model of a textbook; not only is it single-authored, but also it comes with chapter introductions, chapter summaries, worked examples, exercises, and many references to the literature. In addition, this book will serve as...

This handbook documents engineering methodologies for the development of standardized, statistically -based material property data for polymer matrix composite materials. Also provided are data summaries for a number of relevant composite material systems for which available data meets specific MIL-HNBK-17 requirements for publication. Additionall
