Since its commercial introduction in 2004, UHPLC (Ultra-High Performance Liquid Chromatography) has begun to replace conventional HPLC in academia and industry and interest in this technique continues to grow. Both the increases in speed and resolution make this an attractive method; particularly to the life sciences and more than 1500 papers have been written on this strongly-evolving topic to date. This book provides a solid background on how to work with UHPLC and its application to the life sciences. The first part of the book covers the basics of this approach and the specifics of a UHPLC system, providing the reader with a solid background to working properly with such a system. The second part examines the application of UHPLC to the life sciences, with a focus on drug analysis strategies. UHPLC-MS, a key technique in pharmaceutical and toxicological analyses, is also examined in detail. The editors (Davy Guillarme and Jean-Luc Veuthey) were some of the earliest adopters of UHPLC and have published and lectured extensively on this topic. Between them they have brought together an excellent team of contributors from Europe and the United States, presenting a wealth of expertise and knowledge. This book is an essential handbook for anyone wishing to adopt an UHPLC system in either an academic or industrial setting and will benefit postgraduate students and experienced workers alike.

This book, now in its second edition, introduces readers to quantum rings as a special class of modern high-tech material structures at the nanoscale. It deals, in particular, with their formation by means of molecular beam epitaxy and droplet epitaxy of semiconductors, and their topology-driven electronic, optical and magnetic properties. A highly complex theoretical model is developed to adequately represent the specific features of quantum rings. The results presented here are intended to facilitate the development of low-cost high-performance electronic, spintronic, optoelectronic and information processing devices based on quantum rings. This second edition includes both new and significantly revised chapters. It provides extensive information on recent advances in the physics of quantum rings related to the spin-orbit interaction and spin dynamics (spin interference in Rashba rings, tunable exciton topology on type II InAs/GaAsSb quantum nanostructures), the electron-phonon interaction in ring-like structures, quantum interference manifestations in novel materials (graphene nanoribbons, MoS2), and the effects of electrical field and THz radiation on the optical properties of quantum rings. The new edition also shares insights into the properties of various novel architectures, including coupled quantum ring-quantum dot chains and concentric quantum rings, topologic states of light in self-assembled ring-like cavities, and optical and plasmon m.odes in Moebius-shaped resonators.
For the research scientist without formal training in optics and spectroscopy, learning how to make multichannel spectroscopic measurements can be a toilsome, piecemeal affair, requiring extensive reading in original literature and specialized works outside his or her area of expertise. To add to the difficulties, such an undertaking, without proper guidance, invariably leads to countless hours wasted puzzling through a maze of unnecessary mathematics and technical dead ends. Thus, the enterprising analytical chemist or research scientist is often daunted in his or her efforts to learn how to choose and develop the right tools for the job, only to fall back on "leaving it up to the experts." Now, Multielement Detection Systems for Spectrochemical Analysis makes it possible for readers to rapidly develop the knowledge and skills they need to select, use, and tailor appropriate instrumentation for their spectroscopic analyses. One way it achieves those aims is through its unique, step-by-step format. Offering clear, concise explanations, it begins with basic concepts and principles, such as diffraction, interference, and multiplexing, and advances to more complex considerations in optics, transform techniques, solid-state physics, television technology, electron optics, and array-detector technology. And just as importantly, while other works in the field cover either fundamental principles or instrumentation, Multielement Detection Systems for Spectrochemical Analysis offers a balanced, unified treatment of both. It is both an excellent introduction to spectrographic fundamentals, and a comprehensive guide to image detection technology. Requiring only an undergraduate familiarity withelectronics and the principles of atomic absorption and emission spectrochemical instrumental analysis, this in-depth introduction and comprehensive guide follows a consistently clear, succinct style. Throughout, the level of mathematical complexity is kept to a minimum. Multielement Detection Systems for Spectrochemical Analysis is an essential tool for analytical chemists, as well as physicists, engineers, and anyone engaged in research in which optical spectroscopy is used.
