This book highlights the basics of crystal optics methods and refractive index (RI) measurement techniques in various solids, as well as their scientific and technological applications. In addition to new techniques for cases when traditional techniques are impractical, such as for highly refracting powders, anomalous dispersion of light in the studied solid, or for colloids, it also describes conventional methods of RI measurement.

This book (Nanomaterials: Science and Technology) includes11 chapters cover an introduction, methods of preparation, characterization techniques, physical properties, and applications of nanomaterials for students of faculty of Science, engineers, and researchers. The first chapter covers a brief introduction, definition, classification, and properties of nanomaterials. Chapter two focused on the trends of synthesis routes of nanomaterials using various chemical and physical methods. Chapter three presents the latest techniques used in the characterization of different types of nanomaterials. Optical, electrical, magnetic, mechanical, and thermal properties of nanomaterials are explained in chapters four to nine. Chapter nine present an overview of the introduction, structure, properties, production, and applications of carbon nanotubes. Introduction, preparation, application, advantages and disadvantages and future applications in different fields of nano-biomaterials are mentioned in chapter ten. The last chapter highlights the advantages and disadvantages, applications of nanomaterials and their impacts on the environment.
A concise description of models and quantitative parameters in structural chemistry and their interrelations, with 280 tables and >3000 references giving the most up-to-date experimental data on energy characteristics of atoms, molecules and crystals (ionisation potentials, electron affinities, bond energies, heats of phase transitions, band and lattice energies), optical properties (refractive index, polarisability), spectroscopic characteristics and geometrical parameters (bond distances and angles, coordination numbers) of substances in gaseous, liquid and solid states, in glasses and melts, for various thermodynamic conditions. Systems of metallic, covalent, ionic and van der Waals radii, effective atomic charges and other empirical and semi-empirical models are critically revised. Special attention is given to new and growing areas: structural studies of solids under high pressures and van der Waals molecules in gases. The book is addressed to researchers, academics, postgraduates and advanced-course students in crystallography, materials science, physical chemistry of solids.
Controlling national borders has once again become a key concern of contemporary states and a highly contentious issue in social and political life. But controlling borders is about much more than patrolling territorial boundaries at the edges of states: it now comprises a multitude of practices that take place at different levels, some at the edges of states and some in the local contexts of everyday life – in workplaces, in hospitals, in schools – which, taken together, construct, reproduce and contest borders and the rights and obligations associated with belonging to a nation-state. This book is a systematic exploration of the practices and processes that now define state bordering and the role it plays in national and global governance. Based on original research, it goes well beyond traditional approaches to the study of migration and racism, showing how these processes affect all members of society, not just the marginalized others. The uncertainties arising from these processes mean that more and more people find themselves living in grey zones, excluded from any form of protection and often denied basic human rights.
This eBook is a collection of articles from a Frontiers Research Topic. Frontiers Research Topics are very popular trademarks of the Frontiers Journals Series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area! Find out more on how to host your own Frontiers Research Topic or contribute to one as an author by contacting the Frontiers Editorial Office: frontiersin.org/about/contact.
In the 1950s explosives began to be used to generate ultrahigh pressures in condensed substances in order to modify their properties and structure. Notwithstanding the short duration of an explosion, its energy proved to be high enough to perform physical-chemical transformations of substances, and the new method gained wide industrial applications. It has both advan tages and drawbacks in comparison with the traditional method of static compression. The latter method, notorious for its cumbersome and expensive machin ery, allows one to maintain high pressure as long as one pleases and to regu late the temperature of the sample arbitrarily. But, the pressure available is rather limited and f...
