The classical phenomenon of light scattering is one of the most studied t- ics in light-matter interaction and, even today, involves some controversial issues. A present focus of interest for many researchers is the possibility of obtaining information about microstructures, for example surface roughness, and the size, shape and optical properties of particles by means of a n- invasive technique such as the illumination of these objects with light. One of their main tasks is to extract the relevant information from a detailed study of the scattered radiation. This includes: measurement of the light intensity in di erent directions, analysis of its polarization, determination of its stat- tics,etc. Contributionstoresolvingthisproblemareimportantnotonlyfrom the point of view of increasing basic knowledge but also in their applications to several elds of industry and technology. Consider, for example, the pos- bility of distinguishing between di erent types of atmospheric contaminants, biological contaminants in our blood, the detection of microdefects in the manufacturing of semiconductors, magnetic discs and optical components, or the development of biological sensors. During the period September 11-13, 1998, we brought together a group of international experts on light scattering at the Summer School of Laredo at the University of Cantabria. In a series of one-hour lectures, they discussed currentaspectsoflightscatteringfrommicrostructureswithspecialemphasis on recent applications. The present book condenses those lectures into ve parts.

The development of high-quality foods with desirable properties for both consumers and the food industry requires a comprehensive understanding of food systems and the control and rational design of food microstructures. Food microstructures reviews best practice and new developments in the determination of food microstructure.After a general introduction, chapters in part one review the principles and applications of various spectroscopy, tomography and microscopy techniques for revealing food microstructure, including nuclear magnetic resonance (NMR) methods, environmental scanning electron, probe, photonic force, acoustic, light, confocal and infrared microscopies. Part two explores the measurement, analysis and modelling of food microstructures. Chapters focus on rheology, tribology and methods for modelling and simulating the molecular, cellular and granular microstructure of foods, and for developing relationships between microstructure and mechanical and rheological properties of food structures. The book concludes with a useful case study on electron microscopy.Written by leading professionals and academics in the field, Food microstructures is an essential reference work for researchers and professionals in the processed foods and nutraceutical industries concerned with complex structures, the delivery and controlled release of nutrients, and the generation of improved foods. The book will also be of value to academics working in food science and the emerging field of soft matter.

This thesis explores the dispersion stability, microstructure and phase transitions involved in the nanoclay system. It describes the recently discovered formation of colloidal gels via two routes: the first is through phase separation and second is by equilibrium gelation and includes the first reported experimental observation of a system with high aspect ratio nanodiscs. The phase behavior of anisotropic nanodiscs of different aspect ratio in their individual and mixed states in aqueous and hydrophobic media is investigated. Distinct phase separation, equilibrium fluid and equilibrium gel phases are observed in nanoclay dispersions with extensive aging. The work then explores solution behavior, gelation kinetics, aging dynamics and temperature-induced ordering in the individual and mixed states of these discotic colloids. Anisotropic ordering dynamics induced by a water-air interface, waiting time and temperature in these dispersions were studied in great detail along with aggregation behavior of nanoplatelets in hydrophobic environment of alcohol solutions.

It is widely accepted that the creation of novel foods or improvement of existing foods largely depends on a strong understanding and awareness of the intricate interrelationship between the nanoscopic, microscopic and macroscopic features of foods and their bulk physiochemical properties, sensory attributes and healthfulness. With its distinguished editor and array of international contributors, Understanding and controlling the microstructure of complex foods provides a review of current understanding of significant aspects of food structure and methods for its control.Part one focuses on the fundamental structural elements present in foods such as polysaccharides, proteins and fats and the forces which hold them together. Part two discusses novel analytical techniques which can provide information on the morphology and behaviour of food materials. Chapters cover atomic force microscopy, image analysis, scattering techniques and computer analysis. Chapters in part three examine how the principles of structural design can be employed to improve performance and functionality of foods. The final part of the book discusses how knowledge of structural and physicochemical properties can be implemented to improve properties of specific foods such as ice-cream, spreads, protein-based drinks, chocolate and bread dough.Understanding and controlling the microstructure of complex foods is an essential reference for industry professionals and scientists concerned with improving the performance of existing food products and inventing novel food products.

Der Einsatz vernetzungsfähiger Enzyme wurde am Beispiel einer Laccase bzw. Transglutaminase zur Stabilisierung und Modifizierung neuer Verkapselungssysteme untersucht. Ziel der Studien war es insbesondere den Wirkmechanismus der vernetzenden Enzyme in komplexen Lebensmittelmatrizen zu klären. Im Fokus der Forschung stand die Wirkung der Oxidase Laccase auf eine Fischgelatine-Zuckerrübenpektin-stabilisierte Öl-in-Wasser-Emulsion. Die Ergebnisse belegen, dass ausschließlich Biopolymere, die an der unmittelbar zur kontinuierlichen Phase hin zugänglichen Grenzfläche der Öl-in-Wasser Emulsionen durch die Laccase vernetzt werden konnten. In konzentrierten Emulsionssystemen können vernetzende Enzyme neben der Katalyse kovalenter Bindungen innerhalb der Grenzflächenmembran auch Tropfen-Tropfen-Netzwerke induzieren. Die Ausbildung partikulärer Emulsionsgele hängt dabei wesentlich vom mittleren Abstand der Emulsionstropfen ab. Diese Dissertation hat gezeigt, dass vernetzende Enzyme wie Laccase oder Transglutaminase in der Lage sind, die Struktur und Eigenschaften von Lebensmitteldispersion zu modifizieren.

Where conventional testing and inspection techniques fail at the micro-scale, optical techniques provide a fast, robust, and relatively inexpensive alternative for investigating the properties and quality of microsystems. Speed, reliability, and cost are critical factors in the continued scale-up of microsystems technology across many industries, and optical techniques are in a unique position to satisfy modern commercial and industrial demands. Optical Inspection of Microsystems is the first comprehensive, up-to-date survey of the most important and widely used full-field optical metrology and inspection technologies. Under the guidance of accomplished researcher Wolfgang Osten, expert contributors from industrial and academic institutions around the world share their expertise and experience with techniques such as image correlation, light scattering, scanning probe microscopy, confocal microscopy, fringe projection, grid and moiré techniques, interference microscopy, laser Doppler vibrometry, holography, speckle metrology, and spectroscopy. They also examine modern approaches to data acquisition and processing. The book emphasizes the evaluation of various properties to increase reliability and promote a consistent approach to optical testing. Numerous practical examples and illustrations reinforce the concepts. Supplying advanced tools for microsystem manufacturing and characterization, Optical Inspection of Microsystems enables you to reach toward a higher level of quality and reliability in modern micro-scale applications.

Following the Semi-solid Microstructure Workshop sponsored by BASF and hosted by the Rutgers Center for Dermal Research, a pharmaceutical product development working group was formed. The group, known as the Q3 Working Group, selected the following five areas of focus: Particle/Globule Size and Distribution, Viscosity/Rheology/Spreadability, In Vitro Testing, State of API, State of Excipients. A committee was appointed for each of these five areas. The committees were tasked to review the literature, identify best practices, list experimental details required for an independent lab to duplicate the test, and propose scientific studies that may meaningfully advance this specific area of focus. Each committee has a chair (or co-chairs) that are the lead author(s) of the chapter. The Q3 Working Group members serve as the critical reviewers of each chapter, making suggestions that improve the quality of the document and that make each of the five chapters uniform in scope and content.Pharmaceutical development scientists that formulate topical products (creams, lotions, gels suspensions, foams, etc) and all the allied raw material suppliers, packaging suppliers, contract laboratories including CROs, CMOs and regulators need access to this book. Overall, the topic of semisolid microstructure is of equal importance to the generic pharmaceutical companies (filing Abbreviated New Drug Applications or ANDAs) and pharmaceutical companies filing New Drug Applications (NDAs). In addition to products applied to the skin, hair, and nails, The Role of Microstructure in Topical Drug Product Development’ crosses over and is essential reading to developers of oral suspensions, ophthalmic ointments and gels, otic suspension, vaginal semisolids and retention enemas.
