The series ‘The Chemistry of Functional Groups’ was originally planned to cover in each volume all aspects of the chemistry of one of the important functional groups in organic chemistry. The emphasis is laid on the preparation, properties and reactions of the functional group treated and on the effects which it exerts both in the immediate vicinity of the group in question and in the whole molecule. A voluntary restriction on the treatment of the various functional groups in these volumes is that material included in easily and generally available secondary or tertiary sources, such as Chemical Reviews, Quarterly Reviews, Organic Reactions, various ‘Advances’ and ‘Progress’ series and in textbooks (i.e. in books which are usually found in the chemical libraries of most universities and research institutes), should not, as a rule, be repeated in detail, unless it is necessary for the balanced treatment of the topic. Therefore each of the authors is asked not to give an encyclopaedic coverage of his subject, but to concentrate on the most important recent developments and mainly on material that has not been adequately covered by reviews or other secondary sources by the time of writing of the chapter, and to address himself to a reader who is assumed to be at a fairly advanced postgraduate level. |

Изложены современные представления о стехиометрии, термохимии, эргохимии, основах химической кинетики и начала учения о строении атомов молекул, жидкостей, кристаллов и соединений с невалентными связями в свете фундаментальных законов естествознания: сохранения массы-энергии, сохранения заряда и периодического закона элементов Д. И. Менделеева.

Sixty-five years have passed since the publication of Basil Luyet’s Life and Death at Low Temperature , the first organized attempt to summarize past observations of freezing injury in living organisms and to infer from them the mechanisms of injury. Not surprisingly, attention at that time was focused primarily on mechanical damage from ice, although, as evidence of the immaturity of the science, Luyet considered five other possible mechanisms: the withdrawal of energy, attainment of a minimal temperature, too-rapid thawing, dehydration, and “various physiological, physical, or chemical alterations.” One might have expected that the subsequent years would have led to a clear and functional understanding of freezing injury and, as a result, have enabled efficient cryopreservation of almost anything. But it wasn’t that easy. |

Although the use of bioactive natural products as herbal drug preparations dates back hundreds, even thousands, of years ago, their application as isolated and characterized compounds to modern drug discovery and development only started in the 19th century, the dawn of the chemotherapy era. It has been well documented that natural products played critical roles in modern drug development, especially for antibacterial and antitumor agents.1 More importantly, natural products presented scientists with unique chemical structures, which are beyond human imagination most of the time, and inspired scientists to pursue new chemical entities with completely different structures from known drugs. Medicinal chemistry has evolved from the chemistry of bioactive compounds in early days to works at the interface of chemistry and biology nowadays. Medicinal chemistry of bioactive natural products spans a wide range of fields, including isolation and characterization of bioactive compounds from natural sources, structure modification for optimization of their activity and other physical properties, and total and semi-synthesis for a thorough scrutiny of structure activity relationship (SAR). In addition, synthesis of natural products also provides a powerful means in solving supply problems in clinical trails and marketing of the drug, for obtaining natural products in bulk amounts is often very difficult. |

When I was asked by Timber Press to write a new book on resins, including amber—Howes’s 1949 Vegetable Gums and Resins was the most recent such effort—the breadth of interdisciplinary coverage seemed too ambitious for an individual person. There have been so many advances in resin research in the past half century, including the development of new fields of research such as chemical ecology, and the exploration of other interesting facets about resins made possible by new chemical, molecular, and microscopic techniques. With a little thought, however, I realized that my years of resin research had prepared me to accept the challenge enthusiastically, a challenge that has been stimulating and rewarding. |

This is the first monograph of its kind, where a comprehensive and systematic description of modeling and simulation of the smart polymer hydrogels in BioMEMS environment is provided. It will cover the development of the models in form of nonlinear coupled partial differential governing equations for the smart hydrogels. Further, benchmark results, for simulation and prediction of responsive behaviour of the smart hydrogels to solution pH, externally applied electric voltage, environmental temperature, glucose/carbohydrates and salt concentration/ionic strength that are basic stimuli in common BioMEMS devices, are also documented. Finally, it is written in as simple a manner as possible, such that it will make informative and easy reading for the expert, and concurrently it can serve as a rich reference source for a graduate student intending to work in this area. |

The pH electrode offers by far the greatest sensitivity and rangeability of any industrial process measurement. To realize the full potential of this opportunity requires extrao rd inary performance of mixing equipment, contro l valves, reagent delivery systems, flow meters, control system design, and controller tuning. This book is designed to cover all of the bases but not get the user lost in the details. Since each of these topics could be a book in itself, the emphasis here is on cutting straight to the chase of concepts critical for a successful pH system. Key insights and rules of thumb a rc inserted to congeal principles and practices that address the essential requirements of pH applications. The book should appeal to both the generalist and the specialist. This book is designed to bring togethe r the chemist, control engineer, instrument technician, process engineer, and project manager to literally and figuratively put them on the same page. |
