Book Synopsis Interfacial Phenomena and the Marangoni Effect by : M. G. Velarde
Download or read book Interfacial Phenomena and the Marangoni Effect written by M. G. Velarde and published by Springer. This book was released on 2014-05-04 with total page 287 pages. Available in PDF, EPUB and Kindle. Book excerpt: Marangoni (1878), provided a wealth of detailed information on the effects of variations of the potential energy of liquid surfaces and, in particular, flow arising from variations in temperature and surfactant composition. One aspect of this science is seen today to bear on important phenomena associated with the processing of modern materials. The role of the basic effect in technology was probably first demonstrated by chemical engineers in the field of liquid-liquid extraction. Indeed, phenomena attributable to Marangoni flows have been reported in innumerable instances relevant to modern technologies, such as in hot salt corrosion in aeroturbine blades; the drying of solvent-containing paints; the drying of silicon wafers used in electronics; in materials processing, particularly in metallic systems which have been suspected to demonstrate Marangoni flows.

Download or read book Solid-Liquid Two Phase Flow written by Sümer M. Peker and published by Elsevier. This book was released on 2011-04-18 with total page 535 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an undertaking of a pioneering work of uniting three vast fields of interfacial phenomena, rheology and fluid mechanics within the framework of solid-liquid two phase flow. No wonder, much finer books will be written in the future as the visionary aims of many nations in combining molecular chemistry, biology, transport and interfacial phenomena for the fundamental understanding of processes and capabilities of new materials will be achieved. Solid-liquid systems where solid particles with a wide range of physical properties, sizes ranging from nano- to macro- scale and concentrations varying from very dilute to highly concentrated, are suspended in liquids of different rheological behavior flowing in various regimes are taken up in this book. Interactions among solid particles in molecular scale are extended to aggregations in the macro scale and related to settling, flow and rheological behavior of the suspensions in a coherent, sequential manner. The classical concept of solid particles is extended to include nanoparticles, colloids, microorganisms and cellular materials. The flow of these systems is investigated under pressure, electrical, magnetic and chemical driving forces in channels ranging from macro-scale pipes to micro channels. Complementary separation and mixing processes are also taken under consideration with micro- and macro-scale counterparts.- Up-to-date including emerging technologies- Coherent, sequential approach- Wide scope: microorganisms, nanoparticles, polymer solutions, minerals, wastewater sludge, etc- All flow conditions, settling and non-settling particles, non-Newtonian flow, etc- Processes accompanying conveying in channels, such as sedimentation, separation, mixing
Book Synopsis Understanding the Adsorption at Solid-Liquid Interface and Its Consequences on Interfacial Phenomena by : Nishad Dhopatkar
Download or read book Understanding the Adsorption at Solid-Liquid Interface and Its Consequences on Interfacial Phenomena written by Nishad Dhopatkar and published by . 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.
