Synthetic Dyes in Biology, Medicine and Chemistry is a guide in selecting dyes for special purposes in biology, medicine, chemistry, and other related fields. It aims to help professionals including histologists, cytologists, and other biology and medicine experts, such as chemists and general scientists. The dyes discussed in this book are categorized in 17 different classes according to the nature of their salt-forming sidechains, the colligators. This book also presents the uses of each dye. The spectral curve, which is the ionic and/or molecular weight of each dye, is also covered in this book. Likewise, this text provides the structural and empirical formulae of the spectral curve. Part I tackles various groups of dyes. These groups are the non-ionic, anionic, and cationic dyes. The anionic dyes are further grouped as wholly acid, weakly amphoteric, and moderately or strongly amphoteric. The subsequent part deals with the examples of dyes that do not fit the categories mentioned in Part I. These miscellaneous dyes are vat, reactive, disperse, and ingrain dyes. Part III presents the dyes in different tables according to wavelength of maximum absorption and ionic or molecular weight. This book also covers the stabilized diazonium salts and substituted napthols.

In this introduction to each of the major sectors of the chemical industry the authors cover the important chemistry, products, processes and relevant statistics. Each contributor draws on his/her extensive industrial experience to give a balanced coverage which is both easy to read and authoritative. New chapters on quality and safety issues, environmental issues and an extended chapter on chlor-alkali, sulphur and nitrogen industries, reflect the importance of these subjects today.

The Chemistry of Synthetic Dyes, Volume VII covers the synthesis and application of dyes, fluorescent brightening agents, color and electronic states of organic molecules, photochemistry of dyes, and physical chemistry of dyeing. This book is organized into five chapters—sulfur dyes; Bunte salt dyes; state of dye in dyebath and substrate; kinetics, equilibrium, dye-fiber affinity, and mechanisms; and applications of synthetic dyes to biological problems. This compilation specifically discusses the sulfur dyes of known constitution, analysis of sulfur dyes, and chemistry of Bunte salts. The chemical modification of proteins and dyes as antibacterial and therapeutic agents is also treated. This volume is recommended for organic chemists and technologists interested in the synthesis of dyes and their applications.

Fluorescence Microscopy is a precise and widely employed technique in many research and clinical areas nowadays. Fluorescence Microscopy In Life Sciences introduces readers to both the fundamentals and the applications of fluorescence microscopy in the biomedical field as well as biological research. Readers will learn about physical and chemical mechanisms giving rise to the phenomenon of luminescence and fluorescence in a comprehensive way. Also, the different processes that modulate fluorescence efficiency and fluorescence features are explored and explained.

First multi-year cumulation covers six years: 1965-70.

This book presents some of the latest technologies in waste management, and emphasizes the benefits that can be gained from the use of recycled products. Divided into four sections, it deals with phytoremediation, acquatic weed management and the treatment of solid- and water-based wastes, such as those arising from agricultural, industrial and medical activities. With its special emphasis on the utilization of recycled products, this volume will be of interest to students, academicians, policy makers and others who have a practical and academic interest in dealing with the waste society generates.

Worldwide concern in scientific, industrial, and governmental com munities over traces of toxic chemicals in foodstuffs and in both abiotic and biotic environments has justified the present triumvirate of specialized publications in this field: comprehensive reviews, rapidly published progress reports, and archival documentations. These three publications are integrated and scheduled to provide in international communication the coherency essential for nonduplicative and current progress in a field as dynamic and complex as environmental contamination and toxicology. Until now there has been no journal or other publication series reserved exclusively for the diversified literature on "toxic" chemicals in our foods, our feeds, our geographical surroundings, our domestic animals, our wild life, and ourselves. Around the world immense efforts and many talents have been mobilized to technical and other evaluations of natures, locales, magnitudes, fates, and toxicology of the persisting residues of these chemicals loosed upon the world. Among the sequelae of this broad new emphasis has been an inescapable need for an articulated set of authorita tive publications where one could expect to find the latest important world literature produced by this emerging area of science together with documentation of pertinent ancillary legislation.

The increasing world population, competition for arable land and rich fishing grounds, and environmental concerns mandate that we exploit in a sustainable way the earth's available plant and animal resources for human consumption. To that end, food chemists, technologists, and nutritionists engage in a vast number of tasks related to food availabil

Although studies on synthetic dyes have been performed for more than 100 years, their detailed elucidation requires further extensive research. The discovery of novel high polymers, the necessity of supplying a whole range of shades and increasing require ments for dyestuffs of high fastness properties give rise to a permanent search for new dyes. Extensive investigations on dyes were also occasioned by various applications in the field of spectral sensitization and of staining of biological specimens. Another more recent development concerns the lasing properties of some organic dyes. Most of the progress, however, was only achieved by time-consuming, purely empirical approaches and theoretical understanding of the dye properties is only at its very beginnings. The color is the sine qua non of every dye. For this reason organic chemists and color chemists have looked for relations between the "color and constitution" of dye molecules for a long time. This knowlege as a whole is known as "theory of color". The classic theory of color was established abou t 100 years ago by Witt and was signi ficantly extended 50 years later by W. Konig.
