DOWNLOAD EBOOKIn what is an extremely practical and applicable new work, experts provide concise explanations, with examples and illustrations, of the key techniques in this important field. In each case, after basic principles have been reviewed, applications of the experimental techniques are discussed and illustrated with specific examples. Scientists and engineers in research and development will benefit from an application-oriented book that helps them to find solutions to both fundamental and applied problems. They will know that the surfaces and interfaces of polymers play an important role in most of the application areas of polymers, from moulds, foils, and composites, to biomaterials and applications in micro- and nanotechnology.

However in gas-solid chromatography, a considerable quantity of the mobile phase may be adsorbed on the surface of the stationary adsorbent which diminishes the column's effective length and ability to retain solutes. In this respect helium has been found to be preferable to most other gases (GREENE and Roy, 1957) because it is adsorbed to the least extent. 3. Packed columns offer a considerable resistance to flow, which may create a pressure differential between inlet and outlet of sufficient magnitude to cause an unfavorable flow rate through a significant length of the column. A reduced inlet/outlet pressure ratio can be obtained by using light molecular weight gases toward which the column packing shows the greatest permeability. The flow rate of the mobile phase is normally adjusted by altering the column inlet pressure, for which purpose commercial pressure regulators of sufficient accuracy are available. Quantitative measurements of the flow rate can be made by a number of methods, including rotameters, orifice meters, soapfilm flow meters and displacement of water. The former two methods are the most con venient but the least accurate; moreover they create a back pressure and are temperature dependent whereas although the moving soap bubble is cumbersome to employ and unusable for continuous readings, it is preferred when the highest accuracy is required.

DOWNLOAD EBOOKNatural fiber composites have experienced a renaissance over the last two decades as a response to societal demands for developing eco-friendly, biodegradable and recyclable materials. They are now being extensively used in everyday products as well as in automotive, packaging, sports and the construction industries. These fibers require surface treatments in order to improve their properties and interfacial bonding with polymer matrices, and to reduce their hydrophilic character. These methods can be grouped into three major categories: chemical, physical and biological. Chemical methods use chemical reagents to reduce fibers' hydrophilic tendency and thus improve compatibility with the matrix. They also expose more reactive groups on the fibre surface to facilitate efficient coupling with the matrix. Physical methods change structural and surface properties of the fiber and thereby influence the interfacial bonding with matrices, without extensively changing the chemical composition of the fibers. They are cleaner and simpler than the chemical methods. Biological methods use biological agents like fungi, enzymes and bacteria to modify the fiber surface properties. These methods are not toxic like chemical methods and are not energy-intensive like physical methods.Surface Treatment Methods of Natural Fibers and their Effects on Biocomposites presents an overview and recent developments of these methods. All the major methods are reviewed, explaining the science and methodology behind each method. The effects of these methods on various properties of fibers and the biocomposites made from these fibers are analyzed in detail.The book will be an essential reference for academic researchers, materials scientists and engineers, postgraduate students and industrial researchers and development scientists and engineers working on natural fibers and biocomposites. - Extensive coverage of all the surface modification methods (chemical, physical, biological) of natural fibers and its effect on properties of produced composites - The chemical mechanisms which are utilized in surface treatments are discussed in detail and how these affect the interfacial properties and characteristics - Systematic and comprehensive review on surface modifications of natural fibres, and explains how the effect of the surface treatment can be characterized and measured, as well as the effect on properties

DOWNLOAD EBOOKFundamentals of Interface and Colloid Science (FICS) is a standard reference work with an educational nature. The emphasis is on the basic facts and phenomena, which are systematically explained. FICS aims to make interface and colloid science accessible to a wide audience. Interface and colloid science is an important and fascinating field, but one that is often overlooked and undervalued. It has applications as diverse as agriculture, mineral dressing, oil recovery, industrial chemistry, medical science and biotechnology.A deductive approach is followed, with systems of growing complexity being treated as the book progresses. Volume I: Fundamentals (1st ed. 1991, 2nd ed. 1993) reviews the physical chemistry required to understand current literature on interfacial and colloid science. The volume starts from first principles and gradually increases the level. Volume II: Solid-Liquid Interfaces (1995) treats the subject systematically for the first time, including adsorption, double layers and electronkinetics. Volume III: Interface Tension covers interfacial tensions, monolayers and wetting. - Accessible to a wide audience without a detailed knowledge of physics and chemistry - Complex mathematical derivations are kept to a minimum - Treats interfacial and colloidal phenomena from first principles (advanced command of physics and chemistry not required) - Takes the reader from elementary to expert level - Acts as a reference and a textbook - Contains extensive and detailed cumulative subject index

DOWNLOAD EBOOKThis book presents the latest advances in mechanical and materials engineering applied to the machining, joining and modification of modern engineering materials. The contributions cover the classical fields of casting, forming and injection moulding as representative manufacturing methods, whereas additive manufacturing methods (rapid prototyping and laser sintering) are treated as more innovative and recent technologies that are paving the way for the manufacturing of shapes and features that traditional methods are unable to deliver. The book also explores water jet cutting as an innovative cutting technology that avoids the heat build-up typical of classical mechanical cutting. It introduces readers to laser cutting as an alternative technology for the separation of materials, and to classical bonding and friction stir welding approaches in the context of joining technologies. In many cases, forming and machining technologies require additional post-treatment to achieve the required level of surface quality or to furnish a protective layer. Accordingly, sections on laser treatment, shot peening and the production of protective layers round out the book’s coverage.

DOWNLOAD EBOOKMineral additives are widespread in industrial manufacturing processes. So-called mineral fillers are used to extend raw materials and cut costs. Recently minerals and associated inorganics have frequently been used for their functionality and other mineral-specific qualities. The emergence of nanoscale minerals parallels the global pursuit of nanotechnology. The use of these minerals plays an important role in low-cost, high-performance application of nanotechnology. This 21-chapter compilation is for mineral suppliers, industrial users of mineral fillers, and those concerned with new trends in mineral processing and nanotechnology. Contributions by leading international researchers highlight the emerging markets and applications of functional fillers and nanoscale minerals.
