Buch. Condizione: Neu. Neuware - Incidents in the past have made scientists aware of the need for accurate methods of radionuclide analyses in order to estimate the risk to the public from released radioactivity .This book is an authoritative, up-to-date collection of research contributions presented at the 12th International Symposium on Environmental Radiochemical Analysis. Representing the work of leading scientists from across the globe it presents information on analytical radiochemistry, the behaviour of radionuclides in the environment, radioactively contaminated land, fate of radionuclides in natural and engineered environments and behaviour and analysis of nuclear and radionuclides in radioactive wastes. This essential work will be a key reference for graduates and professionals who work across fields involving analytical chemistry, environmental science and technology, and hazards and waste research and disposal.…

Buch. Condizione: Neu. Neuware - Almost 100 years have passed since Trautz and Lewis put forward their collision theory of molecular processes. Today, knowledge of molecular collisions forms a key part of predicting and understanding chemical reactions. This book begins by setting out the classical and quantum theories of atom-atom collisions. Experimentally observable aspects of the scattering processes; their relationship to reaction rate constants and the experimental methods used to determine them are described. The quantum mechanical theory of reactive scattering is presented and related to experimental observables. The role of lasers in the measurement and analysis of reactive molecular collisions is also discussed. Written with postgraduates and newcomers to the field in mind, mathematics is kept to a minimum, and readers are guided to appendices and further reading to gain a deeper understanding of the mathematics involved.…

Buch. Condizione: Neu. Neuware - There is great interest in metallosupramolecular materials because of their use in magnetic, photonic and electronic materials. Functional Metallosupramolecular Materials focuses on the applications of these materials covering the chemistry underlying the synthesis of a variety of ligands to coordinate various metal ions and the generation of 2D and 3D materials based on these constructs.The book starts by looking at different metallosupramolecular systems including naturally occurring functional metallosupramolecular materials; DNA-based metallosupramolecular materials; metallopolymers; metallogels as well as functional materials based on MOFs. Subsequent chapters then systematically cover the different applications such as molecular computation, spin-crossover, light harvesting and as photocatalysts for the production of solar fuels.The book provides an overview of functional metallosupramolecular materials that will be of interest to graduate students, academics and industrial chemists interested in supramolecular chemistry, materials science and the materials applications.…

Buch. Condizione: Neu. Neuware - The crystallisation phase transformation process and the resulting creation of crystalline materials from liquid phase precursors are central to the science and process engineering of materials in their broadest sense. Crystallisation involves two distinct stages: nucleation and growth. Due to the nano-scale size domain within which the nucleation process functions it is a much less understood process compared to the growth process. As a result, elucidating the fundamental physics and chemistry that govern the formation and structure of the nucleation supra-molecular transition state remains one of the truly unresolved 'grand challenges' of the physical sciences. Following the Nucleation - A Transition State to the Directed Assembly of Materials: Faraday Discussion (April 2015), this book brings together the growing body of theoretical and experimental work. It assesses recent progress in this field, highlights on-going challenges, and discusses future work still needed. …

Buch. Condizione: Neu. Neuware - Smart materials stimulated by chemical or biological signals are of interest for many applications as new sensors and actuators, environmental monitoring, process and food control, agriculture and in particular drug targeting. Whilst many books cover responsive materials, this book will concentrate on materials which are stimulated by chemical or biological signals. Written by an experienced editor with contributions from leading experts, each chapter will detail a different material system appealing to graduate students and researchers in academia and interested working in materials science, materials chemistry.…
