Researchers and practitioners who need a solid foundation or reference will find this work invaluable.

This second of two volumes covers the incorporation of periodic structures in waveguides to exploit the Bragg phenomenon, optical fiber sensors, hollow waveguides and micro-resonators as well as a review of the tremendous expansion of terahertz technology for sensing applications.

Analytical Ultracentrifugation of Polymers and Nanoparticles (Hardcover, 2006 ed.): Walter Maechtle, Lars Boerger Analytical Ultracentrifugation of Polymers and Nanoparticles (Hardcover, 2006 ed.)
Walter Maechtle, Lars Boerger
R2,670 Discovery Miles 26 700 Ships in 18 - 22 working days

Analytical ultracentrifugation (AUC) is a powerful method for the characterization of polymers, biopolymers, polyelectrolytes, nanoparticles, dispersions, and other colloidal systems. The method is able to determine the molar mass, the particle size, the particle density and interaction parameters like virial coefficients and association constants. Because AUC is also a fractionation method, the determination of the molar mass distribution, the particle size distribution, and the particle density distribution is possible. A special technique, the density gradient method, allows fractionating heterogeneous samples according to their chemical nature that means being able to detect chemical heterogeneity. The book is divided into chapters concerning instrumentation, sedimentation velocity runs, density gradient runs, application examples and future developments. In particular, the detailed application chapter demonstrates the versatility and power of AUC by means of many interesting and important industrial examples. Thus the book concentrates on practical aspects rather than details of centrifugation theory.

Both authors have many years of experience in an industrial AUC research laboratory of a world leading chemical company.

Gelled Bicontinuous Microemulsions - A New Type of Orthogonal Self-Assembled Systems (Hardcover, 2014 ed.): Michaela Laupheimer Gelled Bicontinuous Microemulsions - A New Type of Orthogonal Self-Assembled Systems (Hardcover, 2014 ed.)
Michaela Laupheimer

Microemulsions and gels are well-known systems, which play a major role in colloidal and interfacial science. In contrast, the concept of gel microemulsions is still quite new. Gelled microemulsions are highly promising for microemulsion applications in which low viscosity is undesirable, such as administering a drug-delivering microemulsion to a certain area of the skin. It is essential to understand the properties of and structures formed in a system combining microemulsion components and a gelator. This PhD thesis by Michaela Laupheimer provides an in-depth discussion of the phase behavior and sol-gel transition of a microemulsion gelled by a low molecular weight gelator as well as the rheological behavior of a gelled bicontinuous microemulsion. Moreover, the microstructure of the gelled bicontinuous system is fully clarified using techniques like self-diffusion NMR and small angle neutron scattering (SANS). By comparing gelled bicontinuous microemulsions with corresponding non-gelled microemulsions and binary gels, it is demonstrated that bicontinuous microemulsion domains coexist with a gelator network and that the coexisting structures possess no fundamental mutual influence. Hence, gelled bicontinuous microemulsions have been identified as a new type of orthogonal self-assembled system.

Progress in Food Contaminant Analysis (Hardcover, 1996 ed.): James Gilbert Progress in Food Contaminant Analysis (Hardcover, 1996 ed.)
James Gilbert
R4,250 Discovery Miles 42 500 Ships in 18 - 22 working days

'Analysis of Food Contaminants' was published in 1984 by Elsevier Applied Science Publishers and 10 years later I was asked to consider producing an updated second edition. Surprisingly little has really changed in a decade in terms of the public interest in food safety and the continued vigilance of Government in monitoring the food supply for contaminants. This means that food contamination in itself is still a very relevant topic. However, much has changed in terms of the techniques now employed in trace analysis. The 1984 book used a combination of an analytical technique and a specific food contaminant problem area per chapter (each written by a specialist) which resulted in a multi-authored text which was mostly application based but provided a good introduction to the 'how' in terms of applying techniques to real problems. Rather than producing a second edition of this text, it seemed on reflection more sensible to produce a new and complementary book, using the same formula as before of application plus technique, but to concentrate on contaminant areas of current interest and to highlight recent advances in techniques. Thus, the present book 'Progress in Food Contaminant Analysis' has originated as a follow-up to 'Analysis of Food Contaminants'.

CRC Handbook of Fundamental Spectroscopic Correlation Charts (Paperback): Thomas J. Bruno, Paris D.N. Svoronos CRC Handbook of Fundamental Spectroscopic Correlation Charts (Paperback)
Thomas J. Bruno, Paris D.N. Svoronos
R4,063 Discovery Miles 40 630 Ships in 10 - 15 working days

From forensics and security to pharmaceuticals and environmental applications, spectroscopic detection is one of the most cost-effective methods for identifying chemical compounds in a wide range of disciplines. For spectroscopic information, correlation charts are far more easily used than tables, especially for scientists and students whose own areas of specialization may lie elsewhere. The CRC Handbook of Fundamental Spectroscopic Correlation Charts provides a collection of spectroscopic information and unique correlation charts for use in the interpretation of spectroscopic measurements. The handbook presents useful analysis and assignment of spectra and structural elucidation of organic and organometallic molecules. The correlation charts are compiled from an extensive search of spectroscopic literature and contain current, detailed information that includes new results for many compounds. The handbook includes graphical data charts for nuclear magnetic resonance spectroscopy of the most useful nuclei, as well as infrared and ultraviolet spectrophotometry. Because mass spectrometry data is not best represented graphically, the data are presented in tabular form, where mass spectrometry can be used for analyses and structural determinations in tandem with other techniques. In addition to presenting absorption bands and intensities for a variety of important functional groups and chemical families, the book also discusses instrument calibration, diagnostics, common solvents, fragmentation patterns, several practical conversion tables, and laboratory safety. Not intended to replace reference works that provide exhaustive spectral charts on specific compound classes, this book fillsthe need for fundamental charts that are needed on a general, day-to-day basis. The CRC Handbook of Fundamental Spectroscopic Correlation Charts is an ideal laboratory companion for students and professionals in academic, industrial, and government labs.

R3,964 Discovery Miles 39 640 Ships in 18 - 22 working days

The contributions in this volume were first presented at a symposium organized by the editors and held at the 214th National Meeting of the American Chemical Society in Las Vegas in September, 1997. The symposium was sponsored by the ACS Division of Agricultural and Food Chemistry and covered recent developments of interest in food analysis. Many changes have occurred since the standard textbooks on food analysis were published: E. coli 0 157: H7 has leaped into prominence, requiring new and rapid methods of detection; MALDI-MS was developed and used in food analysis for the first time; elec tron microscopy, fluorescence spectroscopy, and electrorheology have been applied to cheese, bread, meat, and chocolate, new methods for monitoring and predicting shelf life have been introduced; new techniques for determining the composition of food have evolved. This book includes many emerging approaches which food scientists may find useful and probably will not find in a textbook. The editors thank the authors whose work is presented in these chapters, the Divi sion of Agricultural and Food Chemistry for agreeing to hold the symposium, and our edi tors at Kluwer Academic I Plenum Publishers whose assistance made our task easier.

R2,663 Discovery Miles 26 630 Ships in 18 - 22 working days

The thesis by Merce Pacios exploits properties of carbon nanotubes to design novel nanodevices. The prominent electrochemical properties of carbon nanotubes are used to design diverse electrode configurations. In combination with the chemical properties and (bio)functionalization versatility, these materials prove to be very appropriate for the development of electrochemical biosensors. Furthermore, this work also evaluates the semiconductor character of carbon nanotubes (CNT) for sensor technology by using a field effect transistor configuration (FET). The CNT-FET device has been optimized for operating in liquid environments. These electrochemical and electronic CNT devices are highly promising for biomolecule sensing and for the monitoring of biological processes, which can in the future lead to applications for rapid and simple diagnostics in fields such as biotechnology, clinical and environmental research.

Yin Sun, Kwok Y. Ong
R6,753 Discovery Miles 67 530 Ships in 10 - 15 working days

While it is not possible to predict - or necessarily prevent - terrorist incidents in which chemical warfare agents (CWAs) and toxic industrial chemicals (TICs) are deployed, correctly chosen, fast, and reliable detection equipment will allow prepared rescue workers to respond quickly and minimize potential casualties.

Detection Technologies for Chemical Warfare Agents and Toxic Vapors discusses the principles, instrumentation, and context for applying technologies such as ion mobility spectrometry, infrared spectroscopy, colorimetric chemistry, and flame ionization to the detection of TICs and lethal CWAs. It conveys techniques - some of which have been patented by the authors - developed for generating vapors and closely imitating potential environmental effects in a laboratory setting, specifically for the testing and evaluation of hand-held, portable, and remote devices. This book also provides a comprehensive list of toxic industrial chemicals classified in terms of hazardousness and their physical, chemical, and toxicological properties. Following a brief historical overview, the text also includes a review of federal detection requirements and the government's rationale for preparedness and response.

By providing insight on the behavior of toxic chemicals, the authors hope to minimize the fear and chaotic effect in a potential event involving chemical agents. Well written and accessible to technical and non-technical audiences, no other book focuses on analytical methods and explains current detection devices for chemical warfare agents.

Raghaw Saran
R5,258 Discovery Miles 52 580 Ships in 18 - 22 working days

Trace element analysis plays a prominent role in various fields, from mineralogy and geology to semiconductor manufacture and foods. In geochemical exploration, the analysis of trace elements assumes high significance due to the multifaceted role played by them. The analyte is at the detection limit of many instrumental techniques. This makes their determination difficult This book covers a wide spectrum of destructive and non-destructive analytical techniques and recent developments in them used all over the world, including developing countries, for quantitation of trace elements. With revolutionary progress in the last three to four decades in analytical techniques, several ICP-based techniques like ICP-OES and ICP-MS and other nuclear analytical techniques have enabled determination of trace elements at the ppb level. However, these methods require expensive instrumentation and cannot be made available everywhere. The quality of analytical data is dependent on valid reference standards. The book contains detailed sample preparation in varying matrices and an important chapter on statistical treatment of analytical data for the purpose of quality control and quality assurance. Pulling together, the book, containing the work carried out by the author's group in India, will be useful to analysts involved in geochemical explorations.

Ice Microfluidics - Ice as Size-Tunable Separation Field and Physicochemical Nature of Freeze Concentrated Solutions... Ice Microfluidics - Ice as Size-Tunable Separation Field and Physicochemical Nature of Freeze Concentrated Solutions (Hardcover, 1st ed. 2019)
Arinori Inagawa
R2,653 Discovery Miles 26 530 Ships in 18 - 22 working days

This book explores the possibility of using micro/nanostructures formed on the doped ice surface as a novel separation platform. In addition, it provides comprehensive information on the nature of freeze-concentrated solutions (FCSs) and the ice/FCS interface, which play important roles in the natural environment and industrial processes alike. The book proposes a novel size-selective separation approach using channels formed on the doped ice surface. The separation is based on the physical interaction of analytes with channel walls, which is controlled by varying the channel width through temperature and dopant concentration changes. It also shows the precise control of the channel width to be in a range of 200 nm-4 m and demonstrates the size-selective separation of microspheres, cells, and DNA. The physicochemical properties of FCSs are measured to reveal the nature of the ice/FCS interface, and the zeta potentials of ice are measured by determining EOF rates in a microchannel fabricated in the ice. The deprotonation at OH dangling bonds and adsorption of ions are also discussed. The viscosities of FCSs confined in micro/nanospaces are evaluated by means of two spectroscopic methods. When an FCS is confined in small spaces surrounded by ice, the viscosity increases compared to that in a bulk solution. Interestingly, this viscosity enhancement occurs even though its size is on the micrometer scale. These parameters are essential to discussing the unique phenomena occurring in FCSs. This book provides an explanation of the scientific processes taking place in FCSs, and reveals the potential that frozen solutions hold as innovative micro/nanofluidic devices and reaction platforms.

This thesis presents new methods for the characterization of vegetable oils, with focus in olive oil, according to geographical and botanical origin, genetic variety and other issues influencing product quality. A wide variety of analytical techniques have been employed, such as various chromatographic techniques (different gas and liquid chromatography methods), an electronic nose, infrared spectroscopy and expert-panel evaluation. Several families of minor compounds, with interest as adulteration markers, have been used for method development, including tocopherols, sterols, phenolics, alcohols, proteins and others. Most methods have been enhanced by the application of multivariate chemometrics. The proposed analytical techniques are of interest to investigate fraudulent actions and practices which are detrimental to product quality.
