Available in PDF, EPUB and Kindle. Book excerpt: Although the title of this book is Paper Chemistry, it should be considered as a text about the chemistry of the formation of paper from aqueous suspensions of fibre and other additives, rather than as a book about the chemistry of the raw material itself. It is the subject of what papermakers call wet-end chemistry. There are many other excellent texts on the chemistry of cellulose and apart from one chapter on the accessibility of cellulose, the subject is not addressed here. Neither does the book deal with the chemistry of pulp preparation (from wood, from other plant sources or from recycled fibres), for there are also many excellent texts on this subject. The first edition of this book was a great success and soon became established as one of the Bibles of the industry. Its achievement then was to collect the considerable advances in understanding which had been made in the chemistry of papermaking in previous years, and provide, for the first time, a sound physico chemical basis of the subject. This new edition has been thoroughly updated with much new material added. The formation of paper is a continuous filtration process in which cellulosic fibres are formed into a network which is then pressed and dried. The important chemistry involved in this process is firstly the retention of col loidal material during filtration and secondly the modification of fibre and sheet properties so as to widen the scope for the use of paper and board products.

Download or read book Tailoring Surfaces written by Nicholas D. Spencer and published by World Scientific. This book was released on 2011 with total page 690 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of the book is the modification of surfaces to tailor them for a specific purpose. Using this method of surface modification, materials chosen for their bulk properties (tensile strength, temperature stability, density, price can be optimized for any particular application, which can lead to improved hardness, biological inertness or activity, corrosion resistance, low or high friction or adhesion, water repellency or wettability, or catalytic activity. The works of the author — many of his crucial papers are included — touches upon these surface properties and spans fields including catalysis, analytical surface science, self-assembled monolayers, tribology, biomaterials, superhydrophobicity and polymer coatings.

Download or read book Adsorption of Polyelectrolyte on Colloidal Silica written by YongWoo Shin and published by . This book was released on 2001 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: The adsorbed amounts and interfacial conformations of weak cationic polyelectrolytes (2.5 k and 31 k of poly (dimethylaminoethyl methacrylate), DMAEMA) on colloidal silica were examined in the context of the influence of chain conformation, and the roles of ionization and counterions. The mobility of the polymer in solution is altered at the Bjerrum length, indicating counterion condensation and a conformation change. Variations in pH altered the backbone and surface charge densities, changing the density of contact points for adsorption. Variations in ionic strength screened repulsions among adsorbed oligomers, an effect most apparent at low ionic strengths. NMR solvent relaxation data provided substantial evidence for differences in the anchoring of DMAEMA oligomers and adsorbed trains of a nonionic homopolymer such as polyethylene oxide. DMAEMA adsorbs at a small number of discrete points on side chains while for polyethylene oxide, every monomer on the main backbone can potentially adhere to the surface, giving a less mobile interface from the perspective of the solvent. The other important feature of this model system was that the polycation charge density was greater than that of the substrate. We demonstrate, quantitatively, that the charge overcompensation observed on the isotherm plateau can be directly attributed to the denser positive charge on the adsorbing polycation, and that the ultimate coverage obtained corresponds to the adsorption of one oligomer onto each underlying negative silica charge, when the silica charge is most sparse, at pH 6. This limiting behavior breaks down at higher pHs where the greater silica charge density accommodates single chains adsorbing onto multiple negative sites. Ultimately at the highest pH's, a regime is approached where coil size, not charge distribution, limits the ultimate coverage. Surface charge enhancement is not a cause for charge overcompensation, but a consequence. High affinity adsorption isotherms at dilute concentration were found for high molecular weight DMAEMA. As pH increases, the bound mass decreases more rapidly than the adsorbed amount, suggesting that the DMAEMA layers may contain loops and tails of higher mobility, before adsorption disappears altogether.

This is a critical topic for new materials and devices particularly those built at the nanoscale. This newest volume will address tribological properties of cutting fluids, lubricant performance related to steel surfaces, biolubricants, and novel materials and ways to reduce friction and wear. Scientists from industrial research and development (R&D) organizations and academic research teams in Asia, Europe, the Middle East and North America will participate in the work.
Download or read book Colloidal Dispersions written by William Bailey Russel and published by Cambridge University Press. This book was released on 1991 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book covers the physical side of colloidal science from the individual forces acting between particles smaller than a micrometer that are suspended in a liquid, through the resulting equilibrium and dynamic properties. A variety of internal forces both attractive and repulsive act in conjunction with Brownian motion and the balance between them all decides the phase behaviour. On top of this various external fields, such as gravity or electromagnetic fields, diffusion and non-Newtonian rheology produce complex effects, each of which is of important scientific and technological interest. The authors aim to impart a sound, quantitative understanding based on fundamental theory and experiments with well-characterised model systems. This broad grasp of the fundamentals lends insight and helps to develop the intuitive sense needed to isolate essential features of the technological problems and design critical experiments. The main prerequisites for understanding the book are basic fluid mechanics, statistical mechanics and electromagnetism, though self contained reviews of each subject are provided at appropriate points. Some facility with differential equations is also necessary. Exercises are included at the end of each chapter, making the work suitable as a textbook for graduate courses in chemical engineering or applied mathematics. It will also be useful as a reference for individuals in academia or industry undertaking research in colloid science.

Download or read book Ceramic Processing written by Mohamed N. Rahaman and published by CRC Press. This book was released on 2017-06-27 with total page 526 pages. Available in PDF, EPUB and Kindle. Book excerpt: Many of the properties critical to the engineering applications of ceramics are strongly dependent on their microstructure which, in turn, is dependent on the processing methods used to produce the ceramic material. Ceramic Processing, Second Edition provides a comprehensive treatment of the principles and practical methods used in producing ceramics with controlled microstructure. Covering the main steps in the production of ceramics from powders, the book also provides succinct coverage of other methods for fabricating ceramics, such as sol−gel processing, reaction bonding, chemical vapor deposition and polymer pyrolysis. While maintaining the objectives of the successful first edition, this new edition has been revised and updated to include recent developments and expanded to feature new chapters on additives used in ceramic processing; rheological properties of suspensions, slurries, and pastes; granulation, mixing, and packing of particles; and sintering theory and principles. Intended as a textbook for undergraduate and graduate courses in ceramic processing, the book also provides an indispensable resource for research and development engineers in industry who are involved in the production of ceramics or who would like to develop a background in the processing of ceramics.
