Book Synopsis Characterization of Liquids, Dispersions, Emulsions, and Porous Materials Using Ultrasound by : Andrei S. Dukhin
Download or read book Characterization of Liquids, Dispersions, Emulsions, and Porous Materials Using Ultrasound written by Andrei S. Dukhin and published by Elsevier. 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

Book Synopsis Complex Plasmas And Colloidal Dispersions: Particle-resolved Studies Of Classical Liquids And Solids by : Alexei Ivlev
Download or read book Complex Plasmas And Colloidal Dispersions: Particle-resolved Studies Of Classical Liquids And Solids written by Alexei Ivlev and published by World Scientific Publishing Company. This book was released on 2012-05-30 with total page 337 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many fundamental issues in classical condensed matter physics can be addressed experimentally using systems of individually visible mesoscopic particles playing the role of “proxy atoms”. The interaction between such “atoms” is determined by the properties of the surrounding medium and/or by external tuning. The best-known examples of such experimental model systems are two different domains of soft matter — complex plasmas and colloidal dispersions.The major goal of this book — written by scientists representing both complex plasmas and colloidal dispersions — is to bring the two fields together. In the first part of the book the basic properties of the two systems are summarized, demonstrating huge conceptual and methodological overlap of the fields and emphasizing numerous cross-connections between them and their essential complementarity. This “introductory part” should serve to help each community in understanding the other field better. Simultaneously, this provides the necessary basis for the second part focused on particle-resolved studies of diverse generic phenomena in liquids and solids — all performed with complex plasmas and/or colloidal dispersions. The book is concluded with the discussion of critical open issues and fascinating perspectives of such interdisciplinary research.

Book Synopsis Characterization of Liquids, Nano- and Microparticulates, and Porous Bodies using Ultrasound by : Andrei S. Dukhin
Download or read book Characterization of Liquids, Nano- and Microparticulates, and Porous Bodies using Ultrasound written by Andrei S. Dukhin and published by Elsevier. This book was released on 2010-06-03 with total page 518 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two key words define the scope of this book: 'ultrasound' and 'colloids'. Historically, there has been little real communication between practitioners in these two fields. Although there is a large body of literature devoted to ultrasound phenomenon in colloids, there is little recognition that such phenomena may be of real importance for both the development and applications of colloid science. On the other side, colloid scientists have not embraced acoustics as an important tool for characterizing colloids. The lack of any serious dialogue between these scientific fields is the biggest motivation behind this book. - Covers in detail this multidisciplinary field combining acoustics, electroacoustics, colloid science, analytical chemistry and rheology - Provides a bibliography with more than 1,000 references - Presents theories and their experimental verification, as well as analysis of the methods and hardware pertaining to applications such as pharmaceuticals, ceramics, and polymers
Book Synopsis Amorphous Solid Dispersions by : Navnit Shah
Download or read book Amorphous Solid Dispersions written by Navnit Shah and published by Springer. This book was released on 2014-11-21 with total page 702 pages. Available in PDF, EPUB and Kindle. 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.
