This book was released on 2018-09-14 with total page 388 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanomaterials in Plants, Algae and Microorganisms: Concepts and Controversies: Volume 2 not only covers all the new technologies used in the synthesis of nanoparticles, it also tests their response on plants, algae and micro-organisms in aquatic ecosystems. Unlike most works in the field, the book doesn't focus exclusively on the higher organisms. Instead, it explores the smaller life forms on which they feed. Topics include the impacts of plant development, how different nanoparticles are absorbed by biota, the impact different metals—including silver and rare earth metals—have on living organisms, and the effects nanoparticles have on aquatic ecosystems as a whole. As nanotechnology based products have become a trillion-dollar industry, there is a need to understand the implications to the health of our biota and ecosystems as the earth is increasingly inundated with these materials. - Covers the issues of nanoparticles on more simple organisms and their ecosystems - Draws upon global experts to help increase understanding of the interface mechanisms at the physiological, biochemical, molecular, and even genomic and proteomic level between ENPs and biological systems - Provides a critical assessment of the progress taking place on this topic - Sheds light on future research needs and scientific challenges that still exist in nanoparticle and living organism interactions

Download or read book Investigation of Oxygen Evolution Reaction Catalysts written by Guangyao Gao and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sustainable energy is an important topic with increasing energy demands, worldwide. Hydrogen energy is one of the promising directions in developing new energy resources. One of the promising methods for hydrogen generation is oxygen evolution reaction (OER) process. However, because of the high energy barrier associated with oxygen evolution reaction, novel catalysts are desired to promote catalytic activity. Among others, transition metal oxides have been one of the optimal materials for oxygen evolution reaction. Recent experimental studies have evaluated the catalytic performance of cobalt oxide structures. However, the fundamental details into the mechanism of OER is largely unknown, this study is focused on providing such insights of OER using first-principle calculation with density functional theory. To overcome the underestimation of the band gap, Hubbard correction (Hubbard values U = 3.3 eV for Co, 3.7 eV for Cr) is applied to the PBE functional throughout the calculation. The Hubbard correction values are validated by comparing to the experimental band gap values and the lattice parameters.The electronic properties of pristine and Cr-substituted cobalt oxides structures were investigated by computing their band structures, density of states, and projected density of states. This study clearly reports a strong correlation between the band gap and the concentration of Cr substituted in the substrate framework. The computed band gap stays relatively constant and was consistent with the experimental values of Co3O4 for Cr concentration less than 1.25.

Book excerpt: In this book the author presents an up-to-date summary of existing information on the structure, electronic properties, chemistry and catalytic properties of transition metal oxides.The subjects covered in the book can be divided into three sections. The first (chapters 1 to 3) covers the structural, physical, magnetic, and electronic properties of transition metal oxides. Although the emphasis is on surface properties, relevant bulk properties are also discussed. The second section (chapters 4 to 7) covers surface chemical properties. It includes topics that describe the importance of surface coordinative unsaturation in adsorption, the formation of surface acidity and the role of acidity in determining surface chemical properties, the nature and reactivities of adsorbed oxygen, and the surface chemistry in the reduction of oxides. The third section (chapters 8 to 14) is on the catalytic properties. Various catalytic reactions including decomposition, hydrogenation, isomerization, metathesis, selective oxidation, and reactions involving carbon oxides are discussed. Emphasis is placed more on reaction mechanisms and the role of catalysts than on kinetics and processes. Chapters on the preparation of oxide catalysts and on photo-assisted processes are also included. Whenever appropriate, relationships between various topics are indicated.Written for surface physicists, chemists, and catalytic engineers, the book will serve as a useful source of information for investigators and as a comprehensive overview of the subject for graduate students.

This book was released on 2013-03-09 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is now time for a comprehensive treatise to look at the whole field of electrochemistry. The present treatise was conceived in 1974, and the earliest invitations to authors for contributions were made in 1975. The completion of the early volumes has been delayed by various factors. There has been no attempt to make each article emphasize the most recent situation at the expense of an overall statement of the modern view. This treatise is not a collection of articles from Recent Advances in Electrochemistry or Modern Aspects of Electrochemistry. It is an attempt at making a mature statement about the present position in the vast area of what is best looked at as a new interdisciplinary field. Texas A & M University J. O'M. Bockris University of Ottawa B. E. Conway Case Western Reserve University Ernest Yeager & M University Texas A Ralph E. White Preface to Volume 2 This volume brings together some dozen processes well known to the electro chemist and treats them according to their various degrees of importance. The production of hydrogen is one of the more important processes, particularly with respect to the prospects of a hydrogen economy. No one would doubt, however, that the most commercially important electrochemical processes at the present time are the production of aluminum and of chlorine. Each of these processes has a separate chapter devoted to it.
