Available in PDF, EPUB and Kindle. Book excerpt: Proton Transfer Reaction Mass Spectrometry (PTR-MS) is a rapidly growing analytical technique for detecting and identifying very small quantities of chemical compounds in air. It has seen widespread use in atmospheric monitoring and food science and shows increasing promise in applications such as industrial process monitoring, medical science and in crime and security scenarios. Written by leading researchers, this is the first book devoted to PTR-MS and it provides a comprehensive account of the basic principles, the experimental technique and various applications, thus making this book essential reading for researchers, technicians, postgraduate students and professionals in industry. The book contains nine chapters and is divided into two parts. The first part describes the underlying principles of the PTR-MS technique, including • the relevant ion-molecule chemistry • thermodynamics and reaction kinetics • a discussion of ion sources, drift tubes and mass spectrometers • practical aspects of PTR-MS, including calibration. The second part of the book turns its attention to some of the many applications of PTR-MS, demonstrating the scope and benefits, as well as the limitations, of the technique. The chapters that make up the second part of the book build upon the material presented in the first part and are essentially self-contained reviews focusing on the following topics: • environmental science • food science • medicine • homeland security, and • applications of PTR-MS in liquid analysis.

This book was released on 2012-12-06 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: Charge transport through the transfer of protons between molecules has long been recognized as a fundamental process, which plays an important role in many chemical reactions. In particular, proton transfer through Hydrogen (H-) bonds has been identified as the main mechanism, via which many bio logical functions are performed and many properties of such basic substances as proteins and ice can be understood. In this volume, several of these important aspects of the H-bond are rep resented. As the division in different sections already indicates, present day research in proton teansfer in biochemistry, biology, and the physics of water and ice remains highly active and very exciting. Nearly a decade ago, a novel approach to the study of collective proton motion in H-bonded systems was proposed, in which this phenomenon was explained by the propagation of certain coherent structures called solitons. In the years that followed, the approach ofsoliton dynamics was further extended and developed by many researchers around the world, into a legitimate and useful method for the analysis of proton transfer in H-bonded systems. Dr. Stephanos Pnevmatikos, the original Director of this ARW, was one of the pioneers in the application ofsoliton ideas to the study ofcharge transport through H-bonds. Having used similar concepts himself in his research on 2D lattices) he was convinced energy transfer through molecular chains (and that solitons can play an important role in enhancing our understanding of protonic conductivity.

Download or read book Molecular Mechanisms of Proton coupled Electron Transfer and Water Oxidation in Photosystem II written by Shin Nakamura and published by Springer Nature. This book was released on 2020-01-03 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book reviews photosynthetic water oxidation and proton-coupled electron transfer in photosystem, focusing on the molecular vibrations of amino acid residues and water molecules. Photosynthetic water oxidation performed by plants and cyanobacteria is essential for the sustenance of life on Earth, not only as an electron source for synthesizing sugars from CO2, but also as an O2 source in the atmosphere. Water oxidation takes place at the Mn4CaO5 cluster in photosystem II, where a series of electron transfer reactions coupled with proton transfer occur using light energy. The author addresses the unresolved mechanisms of photosynthetic water oxidation and relevant proton-coupled electron transfer reactions using a combined approach of experimental and computational methods such as Fourier transform infrared difference spectroscopy and quantum chemical calculations. The results show that protonation and hydrogen-bond structures of water molecules and amino acid residues in the protein play important roles in regulation of the electron and proton transfer reactions. These findings and the methodology make a significant contribution to our understanding the molecular mechanism of photosynthetic water oxidation.

Download or read book The Proton in Chemistry written by R.P. Bell and published by Springer Science & Business Media. This book was released on 2013-11-11 with total page 316 pages. Available in PDF, EPUB and Kindle. Book excerpt: The first edition of this book was based on the lectures which I gave at Cornell University during 1958 as George Fisher Baker Lecturer, and I would like to repeat my warmest thanks to Professor F. A. Long and the other members of the Department of Chemistry for their kindness and helpful advice. The present edition was largely written during the tenure of a Visiting Professorship awarded by the Royal Society and the Israeli Academy of Sciences. I am deeply indebted to both of these bodies and also to the hospitality of the Weizmann Institute of Science, in particular to Professor David Samuel and Professor F. S. Klein of the Isotopes Research Department. The subject as a whole has expanded greatly since 1959, especially in two fields, namely, the direct study of fast proton-transfer reactions (notably by the relaxation methods pioneered by Eigen), and the experi mental and theoretical study of hydrogen isotope effects. In order to keep the size of the book within reasonable bounds it has been necessary to adopt a selective policy, and this is particularly the case in Chapter 9 where I have chosen to treat a few types of reaction in some detail rather than to attempt a more complete coverage.
Download or read book Hydrogen Transfer Reactions written by Gabriela Guillena and published by Springer. This book was released on 2016-09-27 with total page 387 pages. Available in PDF, EPUB and Kindle. Book excerpt: The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience. Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.
