In the quantitative determination of new structures, micro-/nano-crystalline materials pose significant challenges. The different properties of materials are structure-dependent. Traditionally, X-ray crystallography has been used for the analysis of these materials. Electron diffraction is a technique that complements other techniques; for example, single crystal X-ray diffraction and powder X-ray diffraction for determination of structure. Electron diffraction plays a very important role when crystals are very small using single crystal X-ray diffraction or very complex for structure solution by powder X-ray diffraction. With the introduction of advanced methodologies, important methods for crystal structural analysis in the field of electron crystallography have been discovered, such as rotation electron diffraction (RED) and automated electron diffraction tomography (ADT). In recent years, large numbers of crystal structures have been solved using electron crystallography.
The present volume of the Gmelin thorium series describes the solid thorium-carbon compounds with the exception of the carbides and coordination compounds of the type 4 ThAn· X B, where B is a neutral ligand. The complex equilibria of the Th + ion with C-containing complexing agents are treated in the ThD1 volume. A first look into this volume demonstrates that a very large number of ThlV complexes has 4 been prepared. This may be explained by the fact that the Th + ion is the largest tetravalent ion of the periodic table. Therefore, the preparation of complexes with, e. g. , multidentate ligands can give a well-established picture of the coordination number as a function of charge and ioni...

This new book provides a comprehensive overview of the health benefits of various natural sources such as fruits, vegetables, herbs, and spices. It covers multiple topics, including the history of nutraceuticals, their advantages and disadvantages, and the various nutrients found in natural food sources. The book also provides detailed advice on how to incorporate nutraceuticals into a healthy diet and helpful tips on identifying and purchasing nutraceuticals. This book examines the current state of nutraceuticals, including their development and use in the medical and commercial fields. It also looks at the potential for developing new nutraceuticals in the future. It covers nanotechnology-based nutraceuticals, role of nanotechnology in nutraceuticals, and the use of nanoparticulate delivery system in nutraceuticals.
Quantum Mechanics has wide applications in experimental physics and theoretical physics, and this book aims at presenting the fundamentals of quantum mechanics in a clear and concise manner. Primarily intended as a textbook for the postgraduate students of physics, it provides a discussion of the physical concepts to introduce the readers to quantum mechanics. The text begins with the formulation of Schrödinger wave mechanics. Then it moves on to give insights into Heisenberg matrix formulation, Dirac notations, Pauli theory of spin and semi-classical theory of radiation. It concludes with the relativistic theory of a single particle and elements of second quantisation including the interaction of radiation with matter. Key Features Comprehensive and lucid discussion on the fundamentals of quantum mechanics. Chapter-end exercises enable to test the conceptual understanding and analytical skills of the students.
The term "metallic glasses" is widely used to denote the amorphous alloys obtained by rapid quenching techniques. These materials are characterized by short range atom ordering without translational periodicity of the structure. Kinetic and thermodynamic metastability is one of the main characteristics generally related to metallic glasses, while their thermally induced microstructural transformations could result in deterioration or improvement of the functional properties. Due to their favorable magnetic, electrical, mechanical, and anti-corrosion properties, metallic glasses as new and attractive materials have found application in many areas of modern industries - electronics, construction industry, aerospace industry; as well as chemistry, biomedicine, and surgery.
