Available in PDF, EPUB and Kindle. Book excerpt: This book covers the physical side of colloidal science from the individual forces acting between particles smaller than a micrometer that are suspended in a liquid, through the resulting equilibrium and dynamic properties. A variety of internal forces both attractive and repulsive act in conjunction with Brownian motion and the balance between them all decides the phase behaviour. On top of this various external fields, such as gravity or electromagnetic fields, diffusion and non-Newtonian rheology produce complex effects, each of which is of important scientific and technological interest. The authors aim to impart a sound, quantitative understanding based on fundamental theory and experiments with well-characterised model systems. This broad grasp of the fundamentals lends insight and helps to develop the intuitive sense needed to isolate essential features of the technological problems and design critical experiments. The main prerequisites for understanding the book are basic fluid mechanics, statistical mechanics and electromagnetism, though self contained reviews of each subject are provided at appropriate points. Some facility with differential equations is also necessary. Exercises are included at the end of each chapter, making the work suitable as a textbook for graduate courses in chemical engineering or applied mathematics. It will also be useful as a reference for individuals in academia or industry undertaking research in colloid science.

Book excerpt: This volume offers a comprehensive guide on the theory and practice of amorphous solid dispersions (ASD) for handling challenges associated with poorly soluble drugs. In twenty-three inclusive chapters, the book examines thermodynamics and kinetics of the amorphous state and amorphous solid dispersions, ASD technologies, excipients for stabilizing amorphous solid dispersions such as polymers, and ASD manufacturing technologies, including spray drying, hot melt extrusion, fluid bed layering and solvent-controlled micro-precipitation technology (MBP). Each technology is illustrated by specific case studies. In addition, dedicated sections cover analytical tools and technologies for characterization of amorphous solid dispersions, the prediction of long-term stability, and the development of suitable dissolution methods and regulatory aspects. The book also highlights future technologies on the horizon, such as supercritical fluid processing, mesoporous silica, KinetiSol®, and the use of non-salt-forming organic acids and amino acids for the stabilization of amorphous systems. Amorphous Solid Dispersions: Theory and Practice is a valuable reference to pharmaceutical scientists interested in developing bioavailable and therapeutically effective formulations of poorly soluble molecules in order to advance these technologies and develop better medicines for the future.

Available in PDF, EPUB and Kindle. Book excerpt: A dispersion is a system of unmixable phases in which one phase is continuous and at least one is finely distributed. Examples are found in many industrial applications, including emulsions, suspensions, foams, and geld. The control of their flow characteristics - rheology - is essential in their preparation, long-term physical stability and application. Filling the need for a practical, up-to-date book connecting the stability/instability of the dispersion to its rheological behavior, this title aids in understanding the principles of rheology and the techniques that can be applied. From the contents: * General Introduction * Interparticle Interactions and Their Combination * Principles of Viscoelastic Behavior * Rheology of Suspensions * Rheology of Emulsions * Rheology of Modifiers, Thickeners, and Gels * Use of Rheological Measurements for Assessment and Prediction of the Long-Term Physical Stability of Formulations (Creaming and Sedimentation)

This book was released on 2017-08-08 with total page 592 pages. Available in PDF, EPUB and Kindle. Book excerpt: Characterization of Liquids, Dispersions, Emulsions and Porous Materials Using Ultrasound, Third Edition, presents a scientific background for novel methods of characterizing homogeneous and heterogeneous liquids (dispersions, emulsions, and gels) as well as porous materials. Homogeneous liquids are characterized in rheological terms, whereas particle-size distribution and zeta potential are parameters of heterogeneous liquids. For porous materials, porosity, pore size, and zeta potential are output characteristics. These methods are based on ultrasound, which opens an opportunity for simplifying the sample preparation by eliminating dilution. This in turn, makes measurements faster, easier, precise, suitable for accurate quality control, PAT, and formulation of complex systems. This book provides theoretical background of acoustics, rheology, colloid science, electrochemistry, and other relevant scientific fields, describing principles of existing instrumentation and, in particular, commercially available instruments. Finally, the book features an extensive list of existing applications. Presents a theoretical multi-disciplinary background of several new ultrasound analytical techniques in one place Validates the theoretical basis of several new analytical techniques Compares the efficiency and applications of various ultrasound techniques Lists many ultrasound applications in colloid chemistry Contains an extensive bibliography on this multidisciplinary topic

Available in PDF, EPUB and Kindle. Book excerpt: The 8th Smithers Rapra conference on Latex and Synthetic Polymer Dispersions gave a very broad picture of the industry. These proceedings cover all the presentations from the two day event which included: The scientific principles underlying latex dipping were described by Professor C. C. Ho, and Dr, Aik Hwee Eng of Ansell spoke about a modern result of dipping - the antimicrobial glove. Very interesting observations about the allergenic potential of synthetic latex gloves compared to those dipped from natural rubber were made by Hardi Tamm of Korymbos. The use of gamma radiation from the very start of the process, as a means of prevulcanization, to the end of the production process, in sterilization, was described by Dr. Rosamma Alex of the Rubber Research Institute of India and Eric Beers of Nordion respectively. The versatility of natural latex was demonstrated in a paper by Dr. Azura of Universiti Sains Malaysia, who showed us how it can be used for the cleaning of compression moulds. Innovative polymer synthesis in the manufacture of latex dispersions was presented by Dr. Joachim Storsberg of the Fraunhofer Institute, and Dr. Soeren Butz of Synthomer told how more clever chemistry could be used to "e;tailor-make"e; pressure sensitive adhesives. The environmental side of the industry was not forgotten, with two presentations from the Malaysian Rubber Board - Muhammad D Syraarani describing an environmentally friendly method for the analysis of magnesium in latex and Dr. Devaraj Veerasamy presenting the use of ultrafiltration to process latex. In a similar vein, Prof. Khairah Haji Badri, of the Universiti Tun Abdul Rahman showed how natural resources such as palm oil can be used to create useful polymers. David Hill of David Hill and Associates described how to carry out Process Validation of dipped condoms and gloves, and the delegates were told how the newest latex for dipping - synthetic polyiosprene - compares with the oldest - natural rubber - by Dr. Bert Krutzer of Kraton. The conference ended with Dr. Siby Varghese of the Rubber Research Institute of India, and Prof. Sabu Thomas of the Mahatma Gandhi University describing recent advances and applications in the field of nanotechnology.

This book was released on 2024-03-06 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The book describes the results of research dealing with two types of petroleum dispersions: water in petroleum fractions and fuels as well as asphaltenes in crude oil. Such industrial research is aimed at acquiring new knowledge useful for improving processes and products. The main goal of the research carried out was to solve problems of refining technology and the exploitation of petroleum products. Some of the developed solutions have been patented and applied in industry. The problem of solubilizing a small technological amount of water in gasoline and diesel fuels with the aid of surfactant compositions has been successfully resolved. This solution has been used in business practice; it also increases the water tolerance of gasoline with 5% ethanol and allows for the effective use of LPG. The coalescence on fibrous barriers for dewatering fractions from the atmospheric distillation of crude oil allowed for the economic removal of dispersed water and additionally - the removal from diesel distillates of a significant part of the mineral contaminations. A coalescing method of removing sodium lye dispersed in heavy gasoline from the FCC process was successfully used in an industrial plant, replacing the sand filter used in Merox technology. The deep dehydration of the hydrotreated kerosene fraction by evaporating water into an inert gas, a nitrogen blanket, was developed. The product was additionally protected against the aging processes. The influence of pyrolysis oil, a waste product of the pyrolysis process, on the physical structure of crude oil was investigated. The results of the laboratory tests were verified in industrial trials in the AVD plant. Positive test results made it possible to use pyrolysis oil on an industrial scale changing the dispersion structure and properties of crude oil as well as distillation results.

Available in PDF, EPUB and Kindle. Book excerpt: Nanocomposite Structures and Dispersions deals with the preparation of gelled, branched and crosslinked nanostructured polymers in the solution free radical polymerization and controlled/living radical polymerization and polymer and composite nanoparticles and nanostructures in disperse systems, the kinetics of direct and inverse disperse polymerizations (microemulsion, miniemulsion, emulsion, dispersion and suspension polymerization), the bottom-up approach building of functionalized nanoparticles, modelling of radical microemulsion polymerization, the characterization of traditional and non-traditional polymer dispersions, the collective properties of nanomaterials and their (bio)applications. This book is designed to bridge that gap and offers several unique features. First, it is written as an introduction to and survey of nanomaterials with a careful balance between basics and advanced topics. Thus, it is suitable for both beginners and experts, including graduate and upper-level undergraduate students. Second, it strives to balance the colloidal aspects of nanomaterials with physical principles. Third, the book highlights nanomaterial based architectures including composite or hybrid conjugates rather than only isolated nanoparticles. A number of ligands have been utilized to biodecorate the polymer and composite nanocarriers. Finally, the book provides an in depth discussion of important examples of reaction mechanisms of bottom-up building of functionalized nanoparticles, or potential applications of nanoarchitectures, ranging from physical to chemical and biological systems.
