Найти книгу: "Wood Modification"

This book is exclusively concerned with wood modification, although many of these processes are generic and can be applied to other lignocellulosic materials. There have been many rapid developments in wood modification over the past decade and, in particular, there has been considerable progress made in the commercialisation of technologies. Topics covered include: The use of timber in the 21st century Modifying the properties of wood Chemical modification of wood: Acetic Anhydride Modification and reaction with other chemicals Thermal modification of wood Surface modification Impregnation modification Commercialisation of wood modification Environmental consideration and future developments This is the first time that a book has covered all wood modification technologies in one text. Although the book covers the main research developments in wood modification, it also puts wood modification into context and additionally deals with aspects of commercialisation and environmental impact. This book is very timely, because wood modification is undergoing huge developments at the present time, driven in part by environmental concerns regarding the use of wood treated with certain preservatives. There has been considerable commercial interest shown in wood modification over the past decade, with products based upon thermal modification, and furfurylation now being actively being marketed. The next few years will see the commercialisation of acetylation and impregnation modification. This is a new industry, but one that has enormous potential. This book will prove useful to all those with an interest in wood modification including researchers, technologists and professionals working in wood science and timber engineering, wood preservation, and well as professionals in the paper and pulp industries, and those with an interest in the development of renewable materials.

An update to the Elliot Wave Principle that corrects a fundamental error The Elliot Wave Principle has been widely adopted as a tool for traders analyzing market cycles, but Ian Copsey has unearthed a fundamental error in the way it defines the structural development of price behavior. Harmonic Elliott Wave: The Case for Modification of R. N. Elliott's Impulsive Wave Structure explains what's wrong with the Principle, outlining a modification that allows for more accurate trading predictions. Revealing the methodology that led to this discovery, the common ratios that link different parts of the wave structure, and providing a wealth of practical examples to explain his findings, Copsey shows how waves really develop, dispelling the misconceptions that have been practiced by Elliotticians for years. Supporting his methods by consistently ensuring that waves are related by common ratios, Copsey helps the reader apply the revised version of the Principle with greater understanding and accuracy. Reveals a fundamental error in the popular Elliot Wave Principle Outlines a tried and tested modification that fixes this mistake and allows for more accurate analysis Offers essential information on applying the new model to the markets With far-reaching implications for traders everywhere, Harmonic Elliott Wave is a must-read for anyone who puts their faith in the Elliot Wave Principle.

The book series «Polymer Nano-, Micro- and Macrocomposites» provides complete and comprehensive information on all important aspects of polymer composite research and development, including, but not limited to, synthesis, filler modification, modeling, characterization as well as application and commercialization issues. Each book focuses on a particular topic and gives a balanced in-depth overview of the respective subfield of polymer composite science and its relation to industrial applications. With the books the readers obtain dedicated resources with infomation relevant to their research, thereby helping to save time and money. In this first volume in the series, authors from leading academic institutions and companies share their first-hand knowledge of nanotube-surface enhancements for use in polymer composites. All the important methods for the functionalization of nanotube fillers, including polymer wrapping, non-covalent modification with nanoparticles, silica layers or entrapped micelles, chemically induced growth of multilayers, techniques based on covalent bonding, such as polmer or quantum dot attachment, and direct polymerization approaches are covered.

A review of the various methodologies for the surface treatment of different types of inorganic spherical and fibrous fillers, describing ball milling, cationic polymerization, vapor phase grafting, plasma treatment and UV irradiation in detail. In addition, the book connects the resulting composite properties to the modified filler surface properties, thus allowing for a purposeful, application-oriented composite design.

The book provides a unique overview on laser techniques and applications for the purpose of improving adhesion by altering surface chemistry and topography/morphology of the substrate. It details laser surface modification techniques for a wide range of industrially relevant materials (plastics, metals, ceramics, composites) with the aim to improve and enhance their adhesion to other materials. The joining of different materials is of critical importance in the fabrication of many and varied products.

n modern polymer science a variety of polymerization methods for the direct synthesis of polymers bearing functional groups are known. However, there is still a large number of functional groups that may either completely prevent polymerization or lead to side reactions. Post-polymerization modification, also known as polymer-analogous modification, is an alternative approach to overcome these limitations. It is based on the polymerization of monomers with functional groups that are inert towards the polymerization conditions but allow a quantitative conversion in a subsequent reaction step yielding a broad range of other functional groups. Thus, diverse libraries of functional polymers with identical average degrees of polymerization but variable side chain functionality may easily be generated. Filling the gap for a book dealing with synthetic strategies and recent developments, this volume provides a comprehensive and up-to-date overview of the field of post-polymerization modification. As such, the international team of expert authors covers a wide range of topics, including new synthetic techniques utilizing different reactive groups for post-polymerization modifications with examples ranging from modification of biomimetic and biological polymers to modification of surfaces. With its guidelines this is an indispensable and interdisciplinary reference for scientists working in both academic and industrial polymer research.
