This book covers the most important results of studying liquid crystal microlasers for the last decade although the pioneering works on this type lasers have been made much earlier (for the history see Chapter 1). In fact, it is the first book on the subject. The main part of the book deals with low-threshold distributed feedback lasers on dye-doped cholesteric liquid crystals. These are helical materials that possess intrinsic periodicity and manifest optical ...
In crystal growth from the liquid phase, convective flows occurring in the melt or solution play a significant role in many aspects of the growth processes. This includes concentration distribution in the liquid phase, crystal composition, microstructures in the grown crystals, and the shape and evolution of the melting/growing interfaces. All these parameters affect the quality of grown crystals. To this end, convection in the liquid phase must be controlled.The ...
Foreword During the recent years a large number of fascinating books appeared covering the ever growing area of zeolites, zeotypes and mesoporous molecular sieves even including the emerging field of metal organic frameworks. In contrast, we decided to prepare this book focused exclusively on zeolites and zeotypes, defined as crystalline microporous materials, to show that they are still one of the most important groups of inorganic materials serving as very well ...
