Rare-Earth Metal Recovery for Green Technologies: Methods and Applications
by Rajesh Kumar JyothiThis book examines the development, use, extraction, and recovery of rare earth metals. Rare earth elements (REEs) occupy a key role in daily life in industrial applications. They are one of the critical elements for energy and sustainable growth. REEs are utilized in many modern electrical and electronic devices such as smart phones, computers, LED lights etc. Recovery of the REEs from secondary resources represents a way to meet the growing demand for electronic devices. Because of their rarity, utility, and importance, the recovery, utilization and recycling of rare earth metals is of utmost importance. This book presents both current methods of processing rare earths from primary and secondary sources and new, green routes for their isolation and purification. The book also addresses their utilization, re-use, reduction, and recycling policies that exist globally. Applications in metallurgy, magnets, ceramics, electronics, and chemical, optical, and nuclear technologies are discussed.
Rare-Earths and Actinides in High Energy Spectroscopy
by Christiane Bonnelle Nissan SpectorThis unique monograph covers recent theoretical and experimental results on the complex character of f electrons in materials containing lanthanides (rare earths) or actinides, such as alpha-cerium and delta-plutonium. It answers the urgent need for a general presentation of the body of experimental and theoretical results presently available in this challenging domain. Some of the fast developing applications of lanthanide and actinide materials are mentioned. Materials containing atoms with an open f shell have electronic and crystalline properties that are controlled by the localized or delocalized character of the f electrons. This book gives a theoretical discussion of the various spectroscopic methods that shed light on the character of the f electrons and on the connection between their localization and the properties of these materials. Part 1 covers the characteristics of the f electrons in atoms and solids and includes a discussion of the properties of lanthanides and actinides in connection with the f electrons. Part 2 describes the various spectroscopic methods that are used to establish the electronic distributions and energies of the states. Examples involve the determination of f electron distributions by high energy spectroscopy methods with separate treatment of the valence and core electrons. Part 3 concentrates on the theoretical treatment of electronic transitions involving f electrons and simulations of the lanthanide spectra, including comparison with the available experimental data. Part 4 discusses the localized or delocalized character of the f electrons in actinides and their compounds, including comparison (analogies & differences) between the 4f and 5f electron materials. This monograph should be of great value for researchers, academics and engineers working in the fields of high energy spectroscopy, electronic and nuclear science and technology, as well as materials involving rare earths and radio-elements.

Raspberry: Breeding, Challenges and Advances
by Julie Graham Rex BrennanRaspberry is a globally-significant soft fruit crop, with increasing interest to consumers due to its versatility and health-related constituents. In this background context, it is therefore timely to consider the present and future status of the raspberry crop, particularly with the advances in the use of molecular tools and plant phenotyping to improve our understanding of improving crop quality and fruit yields. Since the 1980s a wealth of fundamental genomics and metabolomics resources have been developed for soft fruits including linkage maps, physical maps, QTLs and expression tools. However, a number of serious and emerging challenges exist for the raspberry industry, including the plants’ ability to resist major pest and disease burdens and the impact of climate change on crop production, specifically water use and water availability for soft fruit crops.This book aims to address some of these challenges by updating the information known about this important crop, its health value, the major pest and diseases which affect raspberry and approaches for their control, and the speed and precision offered by selective breeding programs by the deployment of molecular tools and linkage maps for germplasm assessment. Understanding the genetic control of commercially and nutritionally important traits and the linkage of these characteristics to molecular markers on chromosomes is the future basis of plant breeding. We will also introduce the opportunity to fast track breeding by improving the speed of phenotypic selection by utilizing imaging sensor technologies, thereby reducing the cost of years of field assessment through developing this knowledge into markers linked to key fruit traits. The chapters of this book will span the knowledge gained from the collaborations between growers, plant breeders, plant physiologists, soil scientists, geneticists, agronomists and physicists which is essential to achieve progress in improving productivity and a sustainable industry.
Rat City: Overcrowding and Urban Derangement in the Rodent Universes of John B. Calhoun
by Jon Adams Edmund Ramsden"Entertaining, phenomenally weird . . . Rat City may well be the world&’s first-ever work of socio-biographical-scientific pop history. . . .a freaky romp down a peculiar passage in the history of ideas, full of oddball cameos (Aldous Huxley! Buckminster Fuller!) and some very sharp science writing."—The New York TimesBehind the internet's viral "Universe 25" experiment and Robert C. O'Brien's iconic novel, Mrs. Frisby and the Secret of NIMH, was one scientist who set out to change the way we view our fellow man — using rats . . .After the Civil War and throughout the twentieth century, cities in northern American states absorbed a huge increase in populations, particularly of immigrants and African Americans from southern states. City governments responded by creating new regulations that were often segregationist — corralling black Americans, for example, into small, increasingly overcrowded neighborhoods, or into high-rise &“projects.&”The situation intensified after World War II, as rising crime and racial unrest swept the nation, and blame fell on the crowded conditions of city life. The hardest-hit populations were left marginalized and voiceless. Enter John B. Calhoun, an ecologist employed by the National Institute of Mental Health to study the effects of overcrowding on rats. From 1947 to 1977, Calhoun built a series of sprawling habitats in which a rat&’s every need was met—except space. The results were cataclysmic. Did a similar fate await our own teeming cities?Rat City is the first book to tell the story of Calhoun&’s experiments, and their extraordinary influence — an enthralling record of urban design and dystopian science. Meticulously researched, it follows Calhoun&’s struggle to solve the problem of crowding before America&’s cities drain into the behavioral sink. And as the &“war on rats&” continues around the world, and our post-pandemic society reevaluates the necessity of urban living, the riveting story of Rat City is more relevant than ever.

Rate Constant Calculation for Thermal Reactions
by Herbert Dacosta Maohong FanProviding an overview of the latest computational approaches to estimate rate constants for thermal reactions, this book addresses the theories behind various first-principle and approximation methods that have emerged in the last twenty years with validation examples. It presents in-depth applications of those theories to a wide range of basic and applied research areas. When doing modeling and simulation of chemical reactions (as in many other cases), one often has to compromise between higher-accuracy/higher-precision approaches (which are usually time-consuming) and approximate/lower-precision approaches (which often has the advantage of speed in providing results). This book covers both approaches. It is augmented by a wide-range of applications of the above methods to fuel combustion, unimolecular and bimolecular reactions, isomerization, polymerization, and to emission control of nitrogen oxides. An excellent resource for academics and industry members in physical chemistry, chemical engineering, and related fields.

Rates of Evolution (Routledge Library Editions: Evolution #2)
by K. S. W. Campbell M. F. DayOriginally published in 1987 Rates of Evolution is an edited collection drawn from a symposium convened to bring together palaeontologists, geneticists, molecular biologists and developmental biologists to examine some aspects of the problem of evolutionary rates. The book asks questions surrounding the study of evolution, such as did large morphological changes really occur rapidly at various times in the geological past, or is the fossil record too imperfect to be of value in assessing rates of morphological change? What is the measure of ‘rapid’ change? Is stasis at any taxonomic level established? Is it possible to relate genomic and morphological change? What is the role of regulatory and executive genes in controlling evolutionary change? Does the transfer of genetic material between different taxa provide the possibility of increasing evolutionary rates? Featuring contributions from leading researchers, this book will interest anthropologists, palaeontology and scientists of evolution and genetics.
