Buch. Condizione: Neu. Neuware - Noting a marked lack of comprehensiveness and/or contemporaneity among typical reference works on chemical etymology, as well as a somewhat spotty coverage of chemical terms and their etymology in comprehensive dictionaries and textbooks the author decided to write an up-to-date desk reference on chemical etymology which would satisfy the needs of casual readers as well as those of more demanding users of etymological lore. Characteristic user-friendly features of the present work include avoidance of cumbersome abbreviations, avoidance of entries in foreign alphabets, and a broad coverage of all chemical disciplines including mineralogy. Biological, medical, geological, physical and mathematical terms are only considered where they appear of interest to mainstream chemists.This book does not provide definitions of terms (unless required in the etymological context) nor guidance as to the timeliness of different nomenclature systems. The typical user will from the outset be well aware of the exact meaning of the terms he or she focuses on and only require the etymological background to be used. Examples of sources which have been drawn upon in the preparation of this book, apart from the extremely useful Internet resource Google, are listed, but an exhausting enumeration would be tiresome and impractical.…

Buch. Condizione: Neu. Neuware - Separation of Isotopes of Biogenic Elements provides a detailed overview of this area of research covering all aspects from the value of isotope effects to their practical use (equilibrium single-stage isotope effect - kinetics and mass transfer - multiplication of the single-stage isotope separation factor - technological peculiarity of processes) with the purpose of extraction from the natural mixture of the enriched and highly concentrated isotopes. In contrast to traditional books on the theory of isotope separation, the theoretical part of the book describes separation in two-phase processes in counter-flow columns. The experimental part of the book presents systematic analysis of specialists in the field of isotope separation in counter-flow columns. This book will be of interest to scientists, engineers and technical workers engaged in isotope separation processes and isotope application in nuclear physics, medicine, agro-chemistry, biology and other areas. This book may also be used in teaching theory and practical aspects in courses on physical chemistry and Isotope separation of light elements by physicochemical methods.…

Buch. Condizione: Neu. Neuware - Chemical Product Design: Towards a Perspective through Case Studies provides a framework for chemical product design problems which are clearly defined together with different solution approaches. This book covers the latest methods and tools currently available in the field and discusses future challenges that the chemical industry is faced with. It focuses on important issues of chemical product design and provides a good overview on industrial chemical product design problems through case studies supplied by leading experts. The editors of Chemical Product Design teach chemical product design at graduate level courses and also serve as consultants for various chemical companies. They have also developed experimental techniques for chemical product design as well as computer-aided design methods and tools.…

Buch. Condizione: Neu. Neuware - Ultrasound is an energy source that has the potential for enhancing many stages of experimental analysis, but analytical chemists generally have limited knowledge of this technique. Analytical Applications of Ultrasound lays the foundations for practicing analytical chemists to consider ways of exploiting ultrasound energy in their research. This timely and unique book covers a broad range of information about ultrasound, providing advances in ultrasound equipment and demonstrations of how this energy has been used to enhance various steps of analysis. Given the limited literature on analytical applications of ultrasound, the authors provide information from other sources that suggest ways in which we can use it in the analytical laboratory. The authors discuss the principles of ultrasound and the variables we must consider in adapting ultrasound to different problems.…

Buch. Condizione: Neu. Neuware - Chemical Kinetics bridges the gap between beginner and specialist with a path that leads the reader from the phenomenological approach to the rates of chemical reactions to the state-of-the-art calculation of the rate constants of the most prevalent reactions: atom transfers, catalysis, proton transfers, substitution reactions, energy transfers and electron transfers. For the beginner provides the basics: the simplest concepts, the fundamental experiments, and the underlying theories. For the specialist shows where sophisticated experimental and theoretical methods combine to offer a panorama of time-dependent molecular phenomena connected by a new rational. Chemical Kinetics goes far beyond the qualitative description: with the guidance of theory, the path becomes a reaction path that can actually be inspected and calculated. But Chemical Kinetics is more about structure and reactivity than numbers and calculations. A great emphasis in the clarity of the concepts is achieved by illustrating all the theories and mechanisms with recent examples, some of them described with sufficient detail and simplicity to be used in general chemistry and lab courses.…
