At the beginning of this series of volumes on Color Chemistry, the editors pointed to a number of events that have served as stimuli for techno logical advances in the field, thus preventing dyestuff manufacturing from becoming what might otherwise be viewed by now as a ‘sunset industry’. The volumes which followed have provided ample evidence for our belief that the field of colour chemistry is very much alive, though arguably in need of further stimulus. For instance, a viable approach to the design of new chromophores and to the design of metal-free acid, direct, and reactive dyes having fastness properties comparable to their metallized counterparts represent the kind of breakthroughs that would help ensure the continued success of this important field. While it must be acknowledged that serendipity ‘smiled’ on our discipline at its inception and has repeated the favor from time to time since then, few would argue against the proposition that most of the significant advances in the technology associated with any scientific discipline result from research designed to enhance our understanding of the fundamental causes for experimental observations, many of which are pursued because they are unexpected, intriguing and intellectually stimulating. Little reflection is required for one who knows the history of the dyestuff industry to realize that this is certainly true in the colour chemistry arena, as it was basic research that led to fiber-reactive dyes, dyes for high technology, and modern synthetic organic pigments.

Exposure and Risk Assessment of Chemical Pollution – Contemporary Methodology


Free Download Exposure and Risk Assessment of Chemical Pollution – Contemporary Methodology By Mahmoud A. Hassanien (auth.), Lubomir I. Simeonov, Mahmoud A. Hassanien (eds.)
2009 | 526 Pages | ISBN: 9048123348 | PDF | 20 MB
The book contains the contributions at the NATO Study Institute on Exposure and Risk Assessment of Chemical Pollution – Contemporary Methodology, which took place in Sofia – Borovetz, Bulgaria, July 1-10, 2008. Rapid advances in mathematics, computer science and molecular biology and chemistry have lead to the development in of a new branch of toxicology called Computational Toxicology. This emerging field is addressing the estimation and prediction of exposure risk and effects of chemicals based on experimental data, measured concentration and biological mechanisms and computational models of biological systems. Mathematical models are also being used to predict the fate and transport of substances in the environment. Because this area is still in its infancy, there has been limited application from governmental agencies to regulating controllable processes, such as registration of new chemicals, determination of estimated exposure and risk based limits and maximum acceptable concentrations in different compartments of the environment – ambient air, waters, soil and food products. However, this is soon to change as the ability to collect, analyze and interpret the required information is becoming increasingly more efficient and cost effective. Full implementation of the new processes have to involve education on both part of the experimentalists who are generating the data and the models, and the risk assessors who will use them to better protect human health and the environment.

Chemical Nomenclature


Free Download Chemical Nomenclature By E. W. Godly (auth.), K. J. Thurlow (eds.)
1998 | 247 Pages | ISBN: 9401060819 | PDF | 5 MB
Chemical nomenclature can be a complicated subject. As a result, most works on the subject are rather dry textbooks and primarily consist of sets of instructions on how to name chemicals. This practical book proves that chemical nomenclature can be interesting, not just a `necessary evil’. Written in a lively and engaging style by experts in their particular fields, this new book provides a general discussion on why good, clear nomenclature is needed. It introduces the reader to the various forms of nomenclature without reading like a textbook. Both `systematic’ and `trivial’ nomenclature systems are used widely (and interchangeably) in chemistry and this new book covers both areas. For example, systematic nomenclature in both the CAS and IUPAC styles is introduced. These systems have many similarities but important differences which the chemist should be aware of. Specialized naming systems are needed for polymers and natural products and these areas are covered in separate chapters. The naming of elements is a very topical subject at the moment and so this is included to ensure a comprehensive coverage. Covering a wide range of topics in the area of nomenclature and acting as an introduction to a varied field, this book will be of interest to industrial chemists as well as students at senior undergraduate and postgraduate level.

Chemical Rocket Propulsion A Comprehensive Survey of Energetic Materials (2024)


Free Download Chemical Rocket Propulsion: A Comprehensive Survey of Energetic Materials by Luigi T. De Luca, Toru Shimada, Valery P. Sinditskii, Max Calabro
English | PDF (True) | 2017 | 1069 Pages | ISBN : 3319277464 | 33.1 MB
Developed and expanded from the work presented at the New Energetic Materials and Propulsion Techniques for Space Exploration workshop in June 2014, this book contains new scientific results, up-to-date reviews, and inspiring perspectives in a number of areas related to the energetic aspects of chemical rocket propulsion. This collection covers the entire life of energetic materials from their conceptual formulation to practical manufacturing; it includes coverage of theoretical and experimental ballistics, performance properties, as well as laboratory-scale and full system-scale, handling, hazards, environment, ageing, and disposal.
