Download or read book A One dimensional Analysis of Sol gel Film coating Drying written by and published by . This book was released on 1998 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Highly porous sol-gel films have potential applications as electrical and thermal insulators, catalyst supports, sensors, and membranes for gas separations. Pore dimensions in these sol-gel films are usually small e.g., on the order of tens of nanometers or less. Their successful fabrications, however, greatly depend on the fundamental understanding of mechanisms that underlie the phenomena of pore evolution, network shrinkage, and stress development since the final microstructure of a solid gel film is strongly affected by composition of its starting sol and its processing conditions. This report documents a simplified one-dimensional analysis of drying a solidifying sol-gel thin film coating supported by an impermeable solid substrate. Portions of this work were presented at the 1994 Annual Joint Meeting of the New Mexico Section of the American Ceramic Society and Materials Research Society in Albuquerque. The authors considered the solid/liquid two phase coexistent regime during the drying solidifying process in which solvent is removed continuously via evaporation, the solid phase grows significantly in mechanical strength, and pore space shrinks appreciably. From overall and differential mass balances and a force balance at equilibrium, coupled with empirical correlations of solid phase modulus and permeability to strain or deformation, the authors followed the evolution of pore space, solid phase elastic stress, and liquid phase hydrodynamic pressure; they also determined their respective values at equilibrium. By assuming microscopic pore shape models, they estimated and compared the predicted mean pore radii. Their simplified one-dimensional analysis shows that the final mean pore radius is controlled by four parameters: pore-liquid surface tension, solid phase modulus, mean pore radius, and porosity at the initial stress-free state. The one-dimensional model can be employed to guide process design and optimization in sol-gel film fabrications.

Download or read book Immobilized Biomolecules in Analysis written by Tony Cass and published by Oxford University Press. This book was released on 1999-01-28 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biomolecules and cells are critical components of biosensors and biomaterials, but in order to function in an artificial environment, they must be immobilized in a manner that does not affect their interaction with target analytes. Biosensors demonstrate that we can harness the incredible functions of living molecules and cells for our own purposes and are therefore at the forefront of technology. Moreover the applications of immobilized biomolecules and cells are expected to expand far beyond biosensor applications and indeed are already used for pharmaceutical production and testing. Biomaterials will become increasing common as they are being developed into toxic filters, artificial organs, and even silicon chips. This book provides a selection of methods for the immobilization of biomolecules and cells on a variety of surface with different geometries and chemistries so that they retain their function and guidelines on which method to use. Also included are the analytical techniques to measure the functionality of immobilized biomolecules. All the protocols have been tried and validated by the authors. Immobilized Biomolecules in Analysis: A Practical Approach is an invaluable guide to all researchers in the fields of biosensors and biomaterials. Research in biosensors is carried out in a wide variety of fields including biochemistry, chemistry, engineering, laboratory medicine, environmental and defence research. The protocols are written so that an extensive prior knowledge of biochemistry is not required to use them.

Book excerpt: Sol-Gel processing methods, first used historically for decorative and constructional materials, were extensively developed in the last century for applications such as glasses, ceramics, catalysts, coatings, composites and fibres. Today they are reaching their full potential, enabling the preparation of new generations of advanced materials not easily accessible by other methods yet using mild, low-energy conditions. The topic is therefore increasingly included in advanced undergraduate, MSc and PhD programmes in the areas of chemistry, physics and materials science. This concise introductory text, written at the advanced undergraduate/first-year postgraduate level, is also suitable as an introduction to the development, mechanisms, chemistry, characterisation methods and applications of the technique. It provides readers with an extensive yet concise grounding in the theory of each area of the subject and details the real and potential applications and the future prospects of sol-gel chemistry.
