Book Description
Self-assembly monolayer (SAM) structures of lipids and macromolecules have been found to play an important role in many industrial and biological phenomena. This book describes two procedures, namely the STM and AFM, that are used to study SAMs at solid surfaces. K.S. Birdi examines the SAMs at both liquid and solid surfaces by using the Langmuir monolayer method. This book is intended for researchers, academics and professionals.

Book Description
This book focuses on photoswitches. The objective of the book is to introduce researchers and graduate course students who are interested in "photon-working switches" not only to the fundamentals but also to the latest research being carried out in this field. Light can reach a target substrate without any physical contact to deliver energy. The energy can induce changes in the structure of the molecules included in the substrate so that its properties and functions are made switchable by light irradiation. When a substrate is able to revert to its original state, this system can be regarded as a "photon-working switch". The terms "photon-working switches" or "photoswitches" are almost equivalent in meaning to "photochromism"; however, they focus on the "switching of functions" of chemical species rather than their "reversible transformation". Most of the authors of this volume are members of PHENICS, an international research group on organic molecular photoswitches composed of research institutions from France, Japan, Russia, China and Germany. Since its inception in 2008, PHENICS has promoted active research to develop the field. This book commemorates the group's eighth year of collaborative research.

Book Description
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.

Book Description
Very thin film materials have emerged as a highly interesting and useful quasi 2D-state functionality. They have given rise to numerous applications ranging from protective and smart coatings to electronics, sensors and display technology as well as serving biological, analytical and medical purposes. The tailoring of polymer film properties and functions has become a major research field. As opposed to the traditional treatise on polymer and resin-based coatings, this one-stop reference is the first to give readers a comprehensive view of the latest macromolecular and supramolecular film-based nanotechnology. Bringing together all the important facets and state-of-the-art research, the two well-structured volumes cover film assembly and depostion, functionality and patterning, and analysis and characterization. The result is an in-depth understanding of the phenomena, ordering, scale effects, fabrication, and analysis of polymer ultrathin films. This book will be a valuable addition for Materials Scientists, Polymer Chemists, Surface Scientists, Bioengineers, Coatings Specialists, Chemical Engineers, and Scientists working in this important research field and industry.
