Book excerpt: Adsorption From Solution discusses the significance of adsorption behavior in thermodynamic terms, with emphasis on the interplay between enthalpic and entropic contributions to the free energy. This book examines the role of simple models and of elementary thermodynamic and statistical mechanical arguments in relation to the concept of surface phase. Organized into 22 chapters, this book starts with an overview of the theoretical model for the solid/liquid interface. This text then proceeds with a discussion of the general thermodynamic treatment of adsorption from mixed solvents, which is designed to apply in situations where adsorbed species may be regarded as distinct from their bulk counterparts. Other chapters discuss the adsorption from solutions of various interfaces of liquid/gas, liquid/liquid, or liquid/solid. The final chapter deals with the roles of adsorption from solution in controlling other phenomena, such as liquid–liquid displacement, wetting, and the forces between colloidal particles. Physicists, chemists, and materials scientists will find this book extremely useful.

Available in PDF, EPUB and Kindle. Book excerpt: Adsorption from Solutions of Non-Electrolytes provides a general discussion of the subject, which has so far been given little or no attention in current textbooks of physical chemistry. A general view of the subject is particularly needed at a time when we wish to see how far it will be possible to use theories of solutions to explain the phenomena of adsorption. The book opens with an introductory chapter on the types of interface, aspects of adsorption from solution, types of adsorption, and classification of systems. This is followed by separate chapters on experimental methods, adsorption at the liquid-solid interface, adsorption from completely miscible and partially liquids, adsorption of gases and solids from solution, adsorption of polymers, and adsorption in multicomponent systems. Subsequent chapters deal with factors influencing competitive adsorption at the liquid-solid interface. adsorption at the liquid-vapor and liquid-liquid interface, kinetics and thermodynamics of adsorption from the liquid phase, the use of columns in adsorption, and use of adsorption from solution to measure surface area.

Available in PDF, EPUB and Kindle. Book excerpt: Interface and colloid science is an important, though often under-valued, branch of science. It has applications and ramifications in domains as disparate as agriculture, mineral dressing, oil recovery, chemical industry, biotechnology, medical science, and many more. Proper application of interface and colloid science requires factual knowledge and insight into the many basic laws of physics and chemistry upon which it is based. Fundamentals of Interface and Colloid Science is the first book to cover this field in the depth neccessary to be a valuable reference and an excellent textbook.From the beginning to the end of the book, systems of growing complexity are treated gradually. The presentation is particularly suited to emphasize that interfaces are not autonomous phases. As a rule, interfacial properties can be varied only by changing the adjoining phases, so that the properties of these bulk phases must be understood first. The text also recognizes common principles behind a variety of phenomena, and helps the reader to understand them and to develop and improve processes. The systematic treatment of the material in the book makes this clear, and makes the text itself an important contribution to the field. Systematic treatment of information An excellent addition to volume I Two chapters contributed by other experts in the field Uses a deductive approach to increase the order of complexity Written by a leading expert in the field Two chapters contributed by other outstanding scientists Uses a systematic and deductive approach First comprehensive review of the topic

This book was released on 2012-12-06 with total page 478 pages. Available in PDF, EPUB and Kindle. Book excerpt: The subject matter of this book is not entirely new in that much has been written about the state of the interfacial chemistry in other textbooks. However, the authors have found that there is really a need for a book which can lead an investigator, a student, or a beginn er through the in-depth understanding and descriptions involved in the derivations and usage of the adsorption equations based on the unified concept of the Gibbs surface excess. The derivation of the original Gibbs equation for the liquid interface has been amplified with reformulations and criticisms. Attempts have been frequently made to relate the surface excess quantities with the thermodynamic properties of the physically defined interfacial phase. In the last two decades, useful applications of the Gibbs equations have been made for the study of adsorption at solid-liquid as weIl as liquid-gas interfaces formed in the presence of the multicomponent solutions in the bulk. These recent treatments become useful for the experimental studies of the adsorption of electrolytes and interfacial properties related to neutral and charged monolayers. The consistency of the experimental results with those to be expected from the theories of the electrical double layer needs careful examination. An attempt has been made to present in a single volume all these developments based on the unified concept of the Gibbs surface excess. The study of the adsorption from solution is of considerable importance in the field of biology and in many other branches of applied science.

This book was released on 2006-09-28 with total page 341 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book opens with a description of fundamental aspects of protein adsorption to surfaces, a phenomenon that plays a key role in biotechnological applications, especially at solid-liquid interfaces. Presented here are methods for studying adsorption kinetics and conformational changes such as optical waveguide lightmode spectroscopy (OWLS). Also described are sensitive bench techniques for measuring the orientation and structure of proteins at solid-liquid interfaces, including total internal reflection ellipsometry (TIRE), dual polarisation interferometry (DPI) and time of flight - secondary ion mass spectrometry (TOF–SIMS). A model study of fibronectin at polymer surfaces is included, as are studies using microporous membranes and textiles with immobilized enzymes for large-scale applications. Biocompatibility, anti-fouling properties and surface modification to modulate the adsorption and activity of biomolecules are among the other topics addressed in this invaluable book.

This book was released on 2017 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Physical adsorption at solid-liquid interface is an effective way to dynamically alter the surface properties text/italics{in-situ} and is prevalent in biology, geoscience, biotechnology, catalysis, food processing, agriculture, textiles, coatings, adhesives and lubricants, and cosmetics Over the last century an extensive framework of the thermodynamics and kinetics of adsorption as well as the intermolecular forces that govern the physical interactions between the substrate, solute, and solvent has been established, helping elucidate the structure of adsorbates. However, there lacks an understanding of the connection between the local conformation of the adsorbed molecules and its influence on the macroscopic interfacial phenomena. In this research we have employed vibrational spectroscopy techniques namely the interface-selective non-linear sum frequency generation (SFG) and linear attenuated total reflectance Fourier transform infrared (ATR-FTIR) in conjugation with contact mechanics to develop the molecular level insights into macroscopic phenomena of wetting, adhesion, and sliding friction. We study the interfacial structure of small molecules (surfactants and solvents) as well as macromolecules adsorbed on model surfaces of sapphire (aluminum oxide) and silicone dioxide. Using SFG, we discovered a strongly coordinated ice-like water layer confined between two charged surfaces, under hydration pressures, formed by the adsorption of a cationic surfactant (cetyl trimethyl ammonium bromide, CTAB) on dissimilar hydrophobic surfaces (phenylethyl trichlorosilane, PETS self-assembled monolayer, and polydimethylsiloxane elastomer, PDMS). This strongly coordinated water structure forms past the surfactant concentration needed for a monolayer surface coverage and is observed to reduce the sliding friction. Correlating interface-selective spectroscopy with hydration forces, and their macroscopic manifestation on adhesion and friction requires us to reconsider how we understand water under confinement and its significance in more complicated interfacial processes prevalent in biology, chemistry, and engineering. To investigate the adsorption of a basic polymer (PMMA) on acidic surfaces in carbon tetrachloride (neutral), Chloroform (acidic), and acetone (basic) solvents, we used SFG and ATR-FTIR to build on to the established concept of acid-base interactions that explains limited adsorption from basic and acidic solutions compared to neutral solution due to competitive interactions. We show that besides the differences in adsorbed amount, chains adsorbed from an acidic solvent adopt a flat conformation with a much smaller ratio of segments of loops and tails to trains compared to those adsorbed from a neutral solvent. Surface interaction parameters alone cannot predict the differences in conformation of chains adsorbed from acidic or neutral solvents. Such differences in the static and dynamic conformations have consequences in understanding the exchange kinetics, colloidal stabilization, chromatographic separations, adhesion and friction, and stabilization of nanocomposites. The adsorption of polyelectrolytes driven by Coulombic interactions becomes complicated when mixed with oppositely charged surfactant which modulates the net charge and solubility of polyelectrolytes in water resulting in a characteristic bulk phase diagram. We have investigated the adsorption from pre-mixed solutions of a cationic polysaccharide (PQ10) and the anionic surfactant sodium dodecyl sulfate (SDS), on an amphoteric alumina surface using quartz crystal microbalance with dissipation (QCMD). By tuning the surface charge of the amphoteric alumina, we confirmed the importance of electrostatic interactions on the adsorption on a hydrophilic charged surface, a suggestion that was made earlier solely based on the measurements on negatively charged surfaces. We also directly correlate the bulk phase transitions at the interface adsorption by observing a maximum extent of adsorption on both negatively and positively charged surfaces from a solution corresponding to the maximum turbidity. Using the Voight based viscoelastic model, QCMD also provided information on the viscosity, shear modulus, and thickness of the adsorbed polymeric complex, findings of which were corroborated by underwater atomic force microscopy (AFM) measurements. Shifting gears from adsorption to understanding the polymer thin films surface structure in different environments, we used SFG to observe the surface restructuring of an amphiphilic glassy homopolymer poly(alpha-hydroxy-n-butyl acrylate, PHNB) from hydrophobic to aqueous environment. We observed relative changes in ordering of hydrophobic and hydroxyl pendant groups upon going from air to water at different temperatures showing their impact on wetting of the polymer surface observed by means of dynamic contact angles measurement.

Download or read book Study of Adsorption of Biological and Nanoparticle Solutions at the Solid liquid Interface written by and published by . This book was released on 2007 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: With advances in micromechanical machining and nanotechnology, the sample volume needed for biological research and other analysis decreases. With small volume, sample-surface interactions including adsorption must be considered. These adsorption effects can be observed by analyzing light reflected from the solid-liquid interface, and the contact angle of a solution on the surface. Presented is the design and construction of an ellipsometer, a device used to analyze light reflected off of a solid-liquid interface to find interfacial properties, including thickness of a thin film formed by adsorption. The taq enzyme is shown to have a large change in contact angle from seventy degrees to about ten degrees over a short (ten minute) time period when placed on an SU-8 substrate, indicating a change in energy at the interface and a large amount of adsorption. Silane substrates are found to produce similar results. Ellipticity of a colloidal gold nanoparticle solution on a glass substrate is also observed, whose results are difficult to interpret due to bulk shifts in the sample. With the ellipsometer running correctly, it can be used for a number of experiments, including spectroscopic ellipsometry and Brewster angle microscopy, with some modifications.
