Book Description
The thesis provides the necessary experimental and analytical tools to unambiguously observe the atomically resolved chemical reactions. A great challenge of modern science has been to directly observe atomic motions during structural transitions, and while this was first achieved through a major advance in electron source brightness, the information content was still limited and new methods for image reconstruction using femtosecond electron diffraction methods were needed. One particular challenge lay in reconciling the innumerable possible nuclear configurations with the observation of chemical reaction mechanisms that reproducibly give the same kind of chemistry for large classes of molecules. The author shows that there is a simple solution that occurs during barrier crossing in which the highly anharmonic potential at that point in nuclear rearrangements couples high- and low-frequency vibrational modes to give highly localized nuclear motions, reducing hundreds of potential degrees of freedom to just a few key modes. Specific examples are given in this thesis, including two photoinduced phase transitions in an organic system, a ring closure reaction, and two direct observations of nuclear reorganization driven by spin transitions. The emerging field of structural dynamics promises to change the way we think about the physics of chemistry and this thesis provides tools to make it happen.

Chaos-based Cryptography
Author: Ljupco Kocarev
Publisher: Springer Science & Business Media
ISBN: 3642205410
Category : Computers
Languages : en
Pages : 400
Book Description
Chaos-based cryptography, attracting many researchers in the past decade, is a research field across two fields, i.e., chaos (nonlinear dynamic system) and cryptography (computer and data security). It Chaos' properties, such as randomness and ergodicity, have been proved to be suitable for designing the means for data protection. The book gives a thorough description of chaos-based cryptography, which consists of chaos basic theory, chaos properties suitable for cryptography, chaos-based cryptographic techniques, and various secure applications based on chaos. Additionally, it covers both the latest research results and some open issues or hot topics. The book creates a collection of high-quality chapters contributed by leading experts in the related fields. It embraces a wide variety of aspects of the related subject areas and provide a scientifically and scholarly sound treatment of state-of-the-art techniques to students, researchers, academics, personnel of law enforcement and IT practitioners who are interested or involved in the study, research, use, design and development of techniques related to chaos-based cryptography.

An Introduction to Coal Technology
Author: N. Berkowitz
Publisher: Elsevier
ISBN: 0323138381
Category : Technology & Engineering
Languages : en
Pages : 362
Book Description
An Introduction to Coal Technology provides an overview explaining what coal is, how it came into being, what its principal physical and chemical properties are, and how it is handled or processed for particular end uses. This book is divided into two parts; the first of which focuses on coal science and the second on technology. This volume is organized into 15 chapters and begins with a brief account of the origin, formation, and distribution of coal, along with its composition, classification, and most important properties. It then turns to beneficiation and handling; combustion; and various partial or complete conversion technologies. The final chapter deals with some aspects of pollution and pollution control. This book provides fairly detailed discussions on coal chemistry, including the molecular structure of coal. The challenges and limitations of coal technology are also considered. This book is intended for scientists and engineers who are active in other fields, but who might want to bring coal within the orbit of their interests, and to advanced students of chemical and mineral engineering who are contemplating careers in coal-related endeavors.
