Research on optically sensitive chromophores containing polymeric films (photoreactive organic thin films, POTF) has exploded during the past decade, and it is continuing to be a very active area of science. Several important phenomena have been discovered, especially at the contact of photochemistry (photoisomerization) and nonlinear optics by the photoisomerization of nonlinear optical molecules in polymers. The material published in the book covers photoreactivity in organic films from the most elementary to the most sophisticated backgrounds, and discusses possible technological uses in views of applications for fast electro-optic modulation, optical data storage, and holography. This book is a comprehensive volume that encompasses the known knowledge on ЗЩЕА research and appllications. |

Plastics and rubbers are two very different, important materials in this modern age that are needed and used a great deal in our everyday life, both in the indoors and the outdoors of our living spaces. However, there is still, controversy almost all the time, about the use of certain ones and hence there is somewhat of a misconception surrounding the use of these materials, with certain beliefs and scare stories about their possible negative effects on human health; i.e., the belief that any form of PVC use can cause cancer. However, today, it is known that it is not PVC itself, but its monomer, vinyl chloride, and certain special additives incorporated with it (i.e., certain phthalates used as plasticisers), which are responsible for these negative effects. And the reality is such that, PVC is being used as blood bags in medical applications successfully, with no problems. Hence, the separation line of ‘whether something is toxic and harmful to health’ or ‘not’, (and if it is, under which conditions) is a very critical issue and therefore, |

Nanoscience and technology has emerged as a frontier area of research today. A great deal of stimulating progress is being made in the world of nanoscience every other day. Research in “Nanochemistry,” chemistry of nanomaterials, has resulted in the developments of newer methods of synthesis of materials with desired structure, composition, and properties of nanomaterials and their related applications.With this rich array of knowledge available, the question arises as to how does a student, a researcher, or materials scientist get an actual feel of nanopowders and get down to the science and art of making them? Chemistry deals with the synthesis and analysis both being complementary are equally important. Prof KC Patil with his training in Inorganic Synthesis and Propellant Chemistry has found a novel and simple method of tailormaking oxide materials. Prof Patil’s method is distinctly different from the other known methods. I am particularly impressed by the simplicity of the process and the choice of the reactants to prepare a variety of oxide materials from alumina to zirconia and their composites. |

The first edition of this book appeared over fifteen years ago. It was the first chemical engineering textbook to combine modeling, simulation, and control. It also was the first chemical engineering book to present sampled-data control. This choice of subjects proved to be popular with both students and teachers and of considerable practical utility. During the ten-year period following publication, I resisted suggestions from the publisher to produce a second edition because I felt there were really very few useful new developments in the field. The control hardware had changed drastically, but the basic concepts and strategies of process control had undergone little change. Most of the new books that have appeared during the last fifteen years are very similar in their scope and content to the first edition. Basic classical control is still the major subject. |

While the estate agent may chant ‘location, location, location!’, and the stock exchange trader shout ‘‘Buy, sell, buy!’’, the editor of a book devoted to hair has to engage in a little bit of buying, selling and unmasking of the hair follicle as the dream location for unrivalled access to myriad processes underlying much of modern and ancient human life and lifestyle. This book, entitled Hair in Toxicology – An Important Bio-Monitor, is part of a new book series Issues in Toxicology from The Royal Society of Chemistry. It is the first book of this kind to be devoted exclusively to the hair follicle and its shaft as an important tool in modern toxicology. This multi-author book will serve as both a reference and a guide to investigations in the biomedical, biochemical and pharmaceutical sciences. Written by investigators from the fields of chemistry, biochemistry and biology, the authors have first-hand knowledge from their chosen sub-specialities and are active contributors to the peer-reviewed scientific literature. |

Aromatic and medicinal plants arc used in the food. flavour, perfumery. pharmaceutical and healthcarc industries. The ir usc is expected to increase every year due to a consumer-led trend towards natura l foods. food and cosmetic additives and complimentary med icine including aromathcrapy. Many branches of industry are searching for alternative. cleaner antimicrobial, antibiot ic. antioxidant and crop-protection agents. The possibility of utilising volatile oils is being investigated as it has been known since antiquity that they possess biological activities. During the last decade many books have been written about herbs and spices. chemical constituents found in various plant families and the ir uses. |

Written by one of the most significant contributors to the progress of protein crystallography, this practical guide contains case studies, a troubleshooting section and pointers on data interpretation. It covers the theory, practice and latest achievements in x-ray crystallography, such that any researcher in structural biology will benefit from this extremely clearly written book. Part A covers the theoretical basis and such experimental techniques as principles of x-ray diffraction, solutions for the phase problem and time-resolved x-ray crystallography. Part B includes case studies for different kinds of x-ray crystal structure determination, such as the MIRAS and MAD techniques, molecular replacement, and the difference Fourier technique. |

Polarised light microscopy is perhaps the most widely applied analytical technique currently used for the identification of historical pigments. Despite the advent of newer methods, polarised light microscopy has maintained a place in this field as a routine and effective approach to the determination of the compounds to be found on painted artefacts. Consequently it may be surprising that no dedicated atlas of pigments has ever been published to support the researcher wishing to carry out such work. |
