Download or read book Physical Properties of Polymers written by A.A. Askadski and published by CRC Press. This book was released on 1996-12-17 with total page 360 pages. Available in PDF, EPUB and Kindle. Book excerpt: New polymeric substances and materials with new, often unusual properties arise frequently. This volume presents a problem in determining the physical properties of polymers and thus makes it difficult to tackle the question of the synthesis of polymers with desired properties. The author has approached this problem in a semi-empirical manner, which like van Krevelen's empirical method is based on the principle of increment and deriving calculations from it, but in Askadskii's approach each equation for the calculation of properties is physically based, and its parameters are connected with characteristics of atoms (Van-der-Waals volume, dispersonic interaction) which compose the reoccurring unit of polymer, as well as with characteristics of energy of intermolecular interaction. Particular attention is paid to the relaxation of properties of polymers, which determine the mechanical serviceability of materials.

Download or read book Adhesion Aspects of Thin Films written by K. L. Mittal and published by VSP. This book was released on 2001-04-03 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book chronicles the proceedings of the First International Symposium on Adhesion Aspects of Thin Films, held in Newark, New Jersey, October 28-29, 1999. Films and coatings are used for a variety of purposes – decorative, protective, functional, etc. – in a host of applications. Irrespective of the intended function or application of a film or a coating, their adequate adhesion to the underlying substrates is of cardinal importance. Concomitantly, the need to understand the factors controlling adhesion and to tailor adhesion to a desired level is quite patent. This book contains a total of 16 papers, which were presented by researchers from academia, industry and other laboratories, and have been rigorously peer reviewed, suitably revised and properly edited before inclusion. The topics covered include: mechanisms, origin, evolution and measurement of stresses in thin films; surface stress effects on the intrinsic stress; various factors affecting stresses in thin films; delamination of coatings caused by residual stress; effects of surface treatments on the adhesion of metallic films; adhesion of CVD diamond to carbide cutting inserts; effect of carbon contaminant on adhesion of aluminum films; effect of interlayers on adhesion of ceramic coatings; effect of residual stress on adhesion and wear resistance of hard coatings; tribological properties of ceramic films; oxide layers as barrier coatings on a plastic substrate; adhesion aspects of organic coatings to metals; and adhesion of thin plasma polymerized fluorocarbon films.This book, providing a commentary on the current state of knowledge of adhesion of thin films, will be useful to anyone interested in thin films and will provide ideas on how to improve or tailor adhesion of a film or a coating for a given situation.

Download or read book Controlled Release written by Liang-tseng Fan and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of controlled release has attracted increasing attention over the last two decades, with the applications of this technology proliferating in diverse fields in cluding medicine, agriculture and biotechnology. Research and developmental efforts related to controlled release are multiplying in both industry and academia. The reason for this phenomenal growth is obvious. The use of a variety of biologically active agents, such as drugs, fertilizers and pesticides, has become an integral part of modern society. Along with the use of these reagents has evolved an awareness that their uncontrolled application almost inevitably induces harmful effects on the health of humans and their surrounding environments. To eliminate or minimize these harmful effects necessitates the controlled release of these chemicals. Moreover, the controlled release of substances, not usually considered toxic or hazardous, e.g., some catalysts and nutrients, can enhance their effectiveness. The number and variety of controlled release systems, differing in their physical and chemical makeup, are increasing rapidly. Proliferation almost always demands correlation, generalization and unification; it requires both the development of underlying theories of their behavior and the mechanistic interpretation of their performance. This, in turn, requires a statistical and mathematical (quantitative) treatment of the scientific information and technical data pertaining to them. A quantitative treatment can also facilitate the formulation of procedures for computer-aided design of these systems through a priori prediction of their per formance for a variety of design parameters.
