Описание: Introduction to Adsorption: Basics, Analysis, and Applications presents adsorption basics that are relevant and essential to its application, including data analysis, interpretation and design calculations. The book deliberately keeps background information to a minimum, instead comprehensively covering adsorption of liquid solutions, the difference between equilibrium individual solute uptake and surface excess, a general discussion of adsorbate uptake mechanisms and uptake rate expression, uptake steps, performance models and their generalizations, application of performance models, and design methods based on the constant behavior assumption and unused bed length concept.

Описание: The declared objective of this book is to provide an introductory review of the various theoretical and practical aspects of adsorption by powders and porous solids with particular reference to materials of technological importance. The primary aim is to meet the needs of students and non-specialists who are new to surface science or who wish to use the advanced techniques now available for the determination of surface area, pore size and surface characterization. In addition, a critical account is given of recent work on the adsorptive properties of activated carbons, oxides, clays and zeolites.

Описание: The author illustrates why the rather weak hydrogen bond is so essential for our everyday life in a lively and entertaining way. The chemical and physical fundamentals are explained with examples ranging from the nature of water over the secret of DNA to adhesives and modern detergents. The interdisciplinary science is easy to understand and hence a great introduction for chemists, biologists and physicists.

Classification based on the structure of the system. General instability problems with emulsions : creaming/sedimentation, flocculation, Ostwald ripening, coalescence and phase inversion. Importance of emulsions in various industrial applications. Chapter 2 Thermodynamics of Emulsion Formation and BreakdownApplication of the second law of thermodynamics for emulsion formation : Balance of energy and entropy and non-spontaneous formation of emulsions. Breakdown of the emulsion by flocculation and coalescence in the absence of an emulsifier. Role of the emulsifier in preventing flocculation and coalescence by creating an energy barrier resulting from the repulsive energies between the droplets. Chapter 3 Interaction Forces between Emulsion DropletsVan der Waals attraction and its dependence on droplet size, Hamaker constant and separation distance between the droplets. Electrostatic repulsion resulting from the presence of electrical double layers and its dependence on surface (or zeta) potential and electrolyte concentration and valency. Combination of the van der Waals attraction with double layer repulsion and the theory of colloid stability. Steric repulsion resulting from the presence of adsorbed non-ionic surfactants and polymers. Combination of van der Waals attraction with steric repulsion and the theory of steric stabilisation. Chapter 4 Adsorption of Surfactants at the Oil/Water InterfaceThermodynamic analysis of surfactant adsorption and the Gibbs adsorption isotherm. Calculation of the amount of surfactant adsorption and area per surfactant molecule at the interface. Experimental techniques for measuring the interfacial tension. Chapter 5 Mechanism of Emulsification and the Role of the EmulsifierDescription of the factors responsible for droplet deformation and its break-up. Role of surfactant in preventing coalescence during emulsification. Definition of the Gibbs dilational elasticity and the Marangoni effect in preventing coalescence. Chapter 6 Methods of EmulsificationPipe flow, static mixers and high speed stirrers (rotor-stator mixer). Laminar and turbulent flow. Membrane emulsification. High pressure homogenisers and ultrasonic methods. Chapter 7 Selection of EmulsifiersThe hydrophilic-lipophilic-balance (HLB) and its application in surfactant selection.

Описание: Recent advances in nanofabrication and subwavelength optical characterisation have led to significant new advances in plasmonics. In addition to traditional top-down nanofabrication techniques, chemical-based fabrication has emerged as an inexpensive and viable alternative with electrochemical and self-organisation methods for fabrication of plasmonic nanoparticles and extended plasmonic structures. This volume aims to highlight the most recent breakthroughs in this multidisciplinary field and hear from the different perspectives of physicists, chemists and biologists. It connects the various subdisciplines in the field and defines the most challenging problems for the future. This volume is focused on areas where progress is expected to have a most significant impact on a whole area of nanoplasmonics and on commercial exploitation. In this volume the topics covered include:Plasmonic nanoparticles and metamaterials with designed optical propertiesSurface plasmon enhanced spectroscopiesQuantum plasmonics, gain and spasersBiosensing and biomedical applications of plasmonics
