Beneath the roots of an ancient tree lies a crystal that keeps the dimensions apart. Jade and Liam unwittingly fall through a tear and end up in a strange and dangerous new world. The fairy realm where mythical creatures are real. To save both their worlds they must find ‘The Crystal Singer’ who dwells in the deepest part of the Pacific Ocean. But their adventure doesn’t end there. They are transported to a planet that is a landscape of bog and black water ponds. Jade finds herself kidnapped with a group of abducted earthlings held prisoner by abandoned robots in a mine beneath the surface. There she must use her wits to help them all escape and reunite with Liam. Then there is Serenity / Renee who exists in two worlds at the same time. How is that possible, and what is her role in this great adventure. And… why has Liam turned blue? Another fast-paced adventure with Jade and Liam and their Alien friends Isa and Zayden. A sequel to ‘The Moon Crystal’. Come along for the ride.

This clear and self-contained review of the last four decades of research highlights in the hot field of nonlinear optical (NLO) crystals, particularly of borate-based ultraviolet and deep-ultraviolet NLO crystals, covers three major subjects: the structure-property relationship in borate crystals, the structural and optical characteristics of various promising borate crystals, and their fruitful applications in a wide range of scientific and technological fields. Edited by the discoverers and users of these optical borate crystals, this is a readily accessible reading for semiconductor, applied and solid state physicists, materials scientists, solid state chemists, manufacturers of optoelectronic devices, and those working in the optical industry.

A fresh new treatment written by industry insiders, this work gives readers a remarkably clear view into the world of chemical separation. The authors review distillation, extraction, adsorption, crystallization, and the use of membranes – providing historical perspective, explaining key features, and offering insights from personal experience. The book is for engineers and chemists with current or future responsibility for chemical separation on a commercial scale – in its design, operation, or improvement – or for anyone wanting to learn more about chemical separation from an industrial point of view. The result is a compelling survey of popular technologies and the profession, one that brings the art and craft of chemical separation to life. Ever wonder how popular separation technologies came about, how a particular process functions, or how mass transfer units differ from theoretical stages? Or perhaps you want some pointers on how to begin solving a separation problem. You will find clear explanations and valuable insights into these and other aspects of industrial practice in this refreshing new survey.

Nanoporous Materials IV contains the invited lectures and peer-reviewed oral and poster contributions to be presented at the 4th International Symposium on Nanoporous Materials, which will be hosted in Niagara Falls, Ontario, Canada, June 7-10, 2005. This volume covers complementary approaches to and recent advances in the field of nanostructured materials with pore sizes larger than 1nm, such as periodic mesoporous molecular sieves (e.g., MCM-41 and SBA-15) and related materials including clays, ordered mesoporous carbons, colloidal crystal templated materials, porous polymers and sol gels. The broad range of topics covered in relation to the synthesis and characterization of ordered mesoporous materials are of great importance for advanced adsorption, catalytic, separation and environmental processes as well as for the development of nanotechnology. This volume contains over 120 contributions related to the synthesis of ordered mesoporous silicas, organosilicas, nonsiliceous inorganic materials, carbons, polymers and related materials, their characterization and applications in adsorption, catalysis and environmental clean up.* Unique contributions brings readers up-to-date on new research and application developments* Figures and tables supplement comprehensive topics * Extensive author and subject index

In this book top experts treat general thermodynamic aspects of crystal fabrication; numerical simulation of industrial growth processes; commercial production of bulk silicon, compound semiconductors, scintillation and oxide crystals; X-ray characterization; and crystal machining. Also, the role of crystal technology for renewable energy and for saving energy is discussed. It will be useful for scientists and engineers involved in crystal and epilayer fabrication as well as for teachers and graduate students in material science, chemical and metallurgical engineering, and micro- and optoelectronics, including nanotechnology.

As different laser technologies continue to make it possible to change laser parameters and improve beam quality and performance, a multidisciplinary theoretical knowledge and grasp of cutting-edge technological developments also become increasingly important. The revised and updated Laser Technology, Second Edition reviews the principles and basic

This text will be replaced by the correThis book is aimed to a broad audience of researchers and students who are interested in questions of structure formation in complex systems in nature and society. When we think of synergetics, impressive images of complex structures immediately come to mind. Such images serve us as starting point and guide for understanding structure formation in chemical, biological, physical, geological, and social systems. Many fascinating pictures of new experimental results illustrate the imagery of synergetics and at the same time enable precise statements about the underlying laws based on precise and discussed measurements. In this way, for example, the famous Runge pictures are accessible to a physico-chemical description, and it turns out that the well-known disintegration of the beer foam satisfies a consecutive kinetics with feedback. The modeling by means of cellular automata and iterated function systems enables us to study the cooperative character of pattern formation on sea shells on the one hand but also to show that creativity is a cooperative effect.ct back cover text / information text as soon as we get it.

This series of books, which is published at the rate of about one per year, addresses fundamental problems in materials science. The contents cover a broad range of topics from small clusters of atoms to engineering materials and involve chemistry, physics, materials science and engineering, with length scales ranging from Ångstroms up to millimeters. The emphasis is on basic science rather than on applications. Each book focuses on a single area of current interest and brings together leading experts to give an up-to-date discussion of their work and the work of others. Each article contains enough references that the interested reader can access the relevant literature. Thanks are given to the Center for Fundamental Materials Research at Michigan State University for supporting this series. M.F. Thorpe, Series Editor E-mail: thorpe @ pa.msu.edu East Lansing, Michigan PREFACE One of the most challenging problems in the study of structure is to characterize the atomic short-range order in materials. Long-range order can be determined with a high degree of accuracy by analyzing Bragg peak positions and intensities in data from single crystals or powders. However, information about short-range order is contained in the diffuse scattering intensity. This is difficult to analyze because it is low in absolute intensity (though the integrated intensity may be significant) and widely spread in reciprocal space.
