Book Synopsis Molecular Design of Interfacial Modifications to Alter Adsorption/desorption Equilibria at Fluid-adjoining Interfaces by : Nicholas J. Musolino
Download or read book Molecular Design of Interfacial Modifications to Alter Adsorption/desorption Equilibria at Fluid-adjoining Interfaces written by Nicholas J. Musolino and published by . This book was released on 2013 with total page 229 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thermodynamics and mass transfer kinetics of adsorption and desporption at interfaces play vital roles in chemical analysis, separation processes, and many natural phenomena. In this work, computer simulations were used to design interfacial modifications to alter the physical processes of adsorption and desorption, using two different approaches to molecular design. In the first application, the finite-temperature string method was used to elucidate the mechanism of water's evaporation at its liquid/vapor interface, with the goal of designing a soluble additive that could impede evaporation there. These simulations used the SPC/E water model, and identified a minimum free energy path for this process in terms of 10 descriptive order parameters. The measured free energy change was 7.4 kcal/mol at 298 K, in reasonable agreement with the experimental value of 6.3 kcal/mol, and the mean first-passage time was 1375 ns for a single molecule, corresponding to an evaporation coefficient of 0.25. In the observed minimum free energy process, the water molecule diffuses to the surface, and tends to rotate so that its dipole and one 0-H bond are oriented outward as it crosses the Gibbs dividing surface. As the molecule moves further outwards through the interfacial region, a local solvation shell tends to protrudes from the interface. The water molecule loses donor and acceptor hydrogen bonds, and then, with its dipole nearly normal to the interface, stops donating its remaining donor hydrogen bond. After the final, accepted hydrogen bond is broken, the water molecule is free. An analysis of reactive trajectories showed that the relative orientation of nearby water molecules, and the number of accepted hydrogen bonds, were important variables in a kinetic description of the process. In the second application, we developed an in silico screening process to design organic ligands which, when chemically bound to a solid surface, would constitute an effective adsorption for a pharmaceutically relevant mixture of reaction products. This procedure employs automated molecular dynamics simulations to evaluate potential ligands, by measuring the difference in adsorption energy of two solutes which differed by one functional group. Then, a genetic algorithm was used to iteratively improve a population of ligands through selection and reproduction steps. This procedure identified chemical designs of the surface-bound ligands that were outside the set considered using chemical intuition. The ligand designs achieved selectivity by exploiting phenyl-phenyl stacking which was sterically hindered in the case of one solution component. The ligand designs had selectivity energies of 0.8 to 1.6 kcal/mol in single-ligand, solvent-free simulations, if entropic contributions to the relative selectivity are neglected. This molecular evolution technique presents a useful method for the directed exploration of chemical space or for molecular design.

Available in PDF, EPUB and Kindle. Book excerpt: As the first of its kind, this book provides a valuable introduction for scientists and engineers interested in liquid/fluid interfaces and disperse systems to the rapidly developing area of adsorption dynamics. It is the first extensive review available on the subject of dynamics of adsorption and gives a general summary of the current state of adsorption kinetics theory and experiments. Current progress in recently designed set-ups and improved and generalised known methods for studying interfacial relaxations is reviewed. In addition, the role of the electric charge of surfactants in the adsorption process is discussed in terms of a non-equilibrium distribution of adsorbing ions in the diffuse layer. Present theories of the effect of dynamic adsorption layers on mobile surfaces, such as moving drops and bubbles, based on both diffusion and kinetic controlled adsorption models are described and efficient approximate analytical methods to solve the mathematical problem of coupling surfactant transport and hydrodynamics are introduced. The role of a dynamic adsorption layer in bubble rising, film drainage and film stabilisation and in complex processes such as flotation and microflotation is discussed. Containing more than 1100 references, the book is essential reading for industrial scientists and graduate and post-graduate students in physical, surface and colloid chemistry, physico-chemical hydrodynamics, water purification and mineral processing.

Book Synopsis Electrokinetics Across Disciplines and Continents by : Alexandra B. Ribeiro
Download or read book Electrokinetics Across Disciplines and Continents written by Alexandra B. Ribeiro and published by Springer. This book was released on 2015-08-25 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: The socio-economic activities due to world development are promoting increasing pressures on land, creating competition and conflicts, resulting in suboptimal use of resources. Integrated planning and management of land resources is a top subject of Agenda 21 (managed by FAO), which deals with the cross-sectoral aspects of decision-making for the sustainable use and development of natural resources. This is essential for life-support systems and its productive capacity. In this context, there is a need to find new strategies for sustainable development that links social and economic progress with environmental protection and enhancement. Electrokinetic transport processes (EK) uses a low-level direct current as the “cleaning agent”. EK has been applied to the remediation of polluted soils and other contaminated matrices. It also shows a great potential to be used in different fields, as in saline soil restoration, nutrients recovery from wastes or repair and maintenance of building structures. EK may be an integrated approach for new strategies aiming at sustainable development and to support waste strategies, with worldwide interest. EK can also be coupled with phytoremediation and integrated with nanotechnology, enlarging the scope of its application. The conciliation of the EK in the recovery of secondary resources, remediation and conservation is a multidisciplinary novel approach that opens new technical possibilities for waste minimization, through upgrading of particulate waste products and the recovery of secondary resources for industrial, agricultural or social use.

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.
