˜The œmaillard reaction : chemistry, biology and implications / par Nursten, H.E. Publication : [S.l.] : Royal Society of Chemistry, 2005 . 214 p. ; , Research in the field of the Maillard reaction has developed rapidly in recent years, not only as a result of the application of improved analytical techniques but also the realisation that that the Maillard reaction plays an important role in some human diseases and in the ageing process. The Maillard Reaction : Chemistry, Biochemistry and Implications provides a comprehensive treatise on the Maillard reaction. This single-author volume covers all aspects of the Maillard reaction in a uniform, co-ordinated, and up-to-date manner. The book encompasses: the chemistry of non-enzymic browning; recent advances; colour formation in non-enzymic browning; flavour and off-flavour formation in non-enzymic browning; toxicological aspects; nutritional aspects; other physiological aspects; other consequences of technological significance; implications for other fields; non-enzymic browning due mainly to ascorbic acid; caramelisation; inhibition of non-enzymic browning in foods; and inhibition of the Maillard reaction in vivo. 24 cm.

Analysis of seawater : a guide for the analytical and environmental chemist / par Crompton, T.R. Publication : [S.l.] : Springer, 2006 . 510 p. ; , It is only in the past few years that methods of adequate sensitivity have become available for true ultra-trace metal determinations in water. In the case of organics in seawater it has now become possible to resolve the complex mixtures of organics in seawater and achieve the required very low detection limits. Fortunately, the interest in micro-constituents in the seawater both from the environmental and the nutrient balance points of view has coincided with the availability of advanced instrumentation capable of meeting the analytical needs. This complete and up-to-date compilation of the currently employed proven methods for the chemical analysis of seawaters includes 45 tables and 48 figures. The author presents the methods in a logical manner so that the reader can readily learn how to perform them and understand the types of instrumentation available. It helps the practitioner to implement these methods successfully into his laboratory and to apply them quickly and reliably. In addition, the detailed description of each method enables the analyst to set up new analytical methods meeting the needs for the detection of new analytes. The volume covers all aspects of the analysis of seawater using both classical and the most advanced recently introduced physical techniques. It is an invaluable source for the analysts, oceanographers, fisheries experts, politicians and decision maker engaged in seawater environmental protection. 24 cm.

Binding and dissociation kinetics for different biosensor applications using fractals par Sadana, Ajit. Publication : [S.l.] Elsevier Science 2006 . 384 p. , The application of biosensors is expanding in different areas. These are portable and convenient devices that permit the rapid, accurate, and reliable detection of analytes of interest present either in the atmosphere or in aqueous or in liquid phases. The detection of glucose levels in blood for the effective management of diabetes is one. Though different biosensors have been designed for an increasing number of applications, the kinetics of binding (and dissociation) of analytes by the receptors on the biosensor surfaces has not been given enough attention in the open literature. This is a very important area of investigation since it significantly impacts biosensor performance parameters such as stability, sensitivity, selectivity, response time, regenerability, etc. Binding and Dissociation Kinetics for Different Biosensor Applications Using Fractals addresses this critical need besides helping to correct or demonstrate the need to modify the present software available with commercial biosensors that determines the kinetics of analyte-receptor reactions on biosensor surfaces. * first book to provide detailed kinetic analysis of the binding and dissociation reactions that are occuring on the biosensor surface * addresses the area of analyte-receptor binding and dissociation kinetics occurring on biosensor surfaces * provides physical insights into reactions occuring on biosensor surfaces. 24 cm.

Bioactive natural products Part E par Rahman, Atta-ur Publication : Amsterdam Elsevier Science 2000 . 1156 p. , Natural products play an integral and ongoing role in promoting numerous aspects of scientific advancement, and many aspects of basic research programs are intimately related to natural products. The significance, therefore, of the Studies in Natural Product Chemistry series, edited by Professor Atta-ur-Rahman, cannot be overestimated. This volume, in accordance with previous volumes, presents us with cutting-edge contributions of great importance. 25 cm.

Biotransformations in organic chemistry : a textbook / par Faber, Kurt. Publication : [S.l.] : Springer, 2004 . 454 p. ; , The use of biocatalysts, employed either as isolated enzymes or whole microbial cells, offers a remarkable arsenal of highly selective transformations for state-of-the-art synthetic organic chemistry. Over the last two decades, this methodology has become an indispensable tool for asymmetric synthesis, not only at the academic level, but also on an industrial scale. This well-established textbook on biocatalysis provides a basis for undergraduate and graduate courses in modern organic chemistry, as well as a condensed introduction into this field. After a basic introduction into the use of biocatalysts ? principles of stereoselective transformations, kinetics and enzyme properties ? the different types of reactions are explained according to the 'reaction principle', such as hydrolysis, reduction, oxidation, C-C bond formation, etc. Special techniques, such as the use of enzymes in organic solvents, immobilization techniques and the use of modified enzymes, are treated in a separate section. A final chapter deals with the basic rules for the safe and practical handling of biocatalysts. In this revised and corrected 5th edition, emphasis has been given to an improved didactic style in order to facilitate a deeper understanding of the underlying principles. New developments, such as dynamic resolution, stereo-inversion and enantio-convergent processes are included. 23 cm.

Physical chemistry of polymer rheology / par Furukawa, Junji. Publication : [S.l.] : Springer, 2003 . 280 p. ; , Rheology is the science and technology that deals with the deformation of polymeric or plastic materials. In this monograph the field of polymer rheology is explained with emphasis on the chemical theory. The book provides basic information on rheology for nonspecialists and gives clear explanations of the various phenomena. The author has developed a new theory of thermodynamics and kinetics using a model of multi-size pseudo crosslinks that provides a comprehensive principle to show how links in chain molecules affect the melting temperatures and determine polymer properties such as viscoelasticity, melt viscosity and elastic and plastic behaviour of bulk polymers. The theory can be extended to include the strength of rubber and plastics, active fillers and adhesion, friction and abrasion. 24 cm.

The theory of classes of groups / par Wenbin, Guo. Publication : [S.l.] : Springer, 2001 . 264 p. ; , This book gives a systematic introduction to the theory of classes of groups, including research subjects, major (recent) research achievements, and directions for future research.
