Book Description :

This book was developed from the proceedings of the 2nd North American Tan nin Conference held in Houghton, Michigan, June, 1991. The objective of this con ference was to bring together people with a common interest in plant polyphenols and to promote interdisciplinary interactions that will lead to a bet ter understand ing of the importance of these substances. Another objective of this conference was to extend the 'tannin family' by making special efforts to encourage participation by scientists outside the United States, obtain more coverage of the hydrolyzable tannins, and further broaden the scope of coverage from the initial concentration on forestry and forest products. Com parison of the contents of this book with 'Chemistry and Significance of Condensed Tannins' that resulted from the proceedings of the 1st North American Tannin Conference shows the degree that these objectives were met. In developing the second conference, care was taken to assure that this book extends rather than duplicates the coverage of the first conference. Therefore, the two books should be taken together to obtain an up to date coverage of the broad area of chemistry and significance of plant polyphenols. Our thanks go to the authors who so kindly contributed chapters and so pa tiently responded to our requests. We thank the Conference Assistance Staff of Michigan Technological University for their help in planning and conducting the conference.

Book Description :

The book is a comprehensive treatment of the subject covering a wide range of subjects uniquely available in a single source for the first time. A material science approach has been adopted in dealing with wood adhesion and adhesives. The approach of the authors was to bring out hierarchical cellular and porous characteristics of wood with polymeric cell wall structure, along with the associated non-cell wall extractives, which greatly influence the interaction of wood substrate with polymeric adhesives in a very unique manner not existent in the case of other adherends. Environmental aspects, in particular formaldehyde emission from adhesive bonded wood products, has been included. A significant feature of the book is the inclusion of polymeric matrix materials for wood polymer composites.

Book Description :

Today, mainly man-made materials, such as carbon and glass fibers, are used to produce composite parts in aviation. Renewable materials, such as natural fibers or bio-sourced resin systems, have not yet found their way into aviation. The project ECO-COMPASS aims to evaluate the potential applications of ecologically improved composite materials in the aviation sector in an international collaboration of Chinese and European partners. Natural fibers such as flax and ramie will be used for different types of reinforcements and sandwich cores. Furthermore, bio-based epoxy resins to substitute bisphenol-A based epoxy resins in secondary structures are under investigation. Adapted material protection technologies to reduce environmental influence and to improve fire resistance are needed to fulfil the demanding safety requirements in aviation. Modelling and simulation of chosen eco-composites aims for an optimized use of materials while a Life Cycle Assessment aims to prove the ecological advantages compared to synthetic state-of-the-art materials. This Special Issue provides selected papers from the project consortium partners.

Book Description :

Wood Extractives and their Significance to the Pulp and Paper Industries focuses on the promotion of the study of the biochemistry of wood extractives and to elaborate on the effects these materials may pose to the manufacture of pulp and paper. The publication first elaborates on wood, distribution and formation of polyphenols within the tree, and the simple polyphenolic constituents of plants. Discussions focus on the factors affecting the amounts of polyphenols present in living tissues, glycosidic combination, flavonols, anthocyanins, and leucoanthocyanins, formation of carbohydrates in the tree, types of polyphenols in different tissues of uninjured trees, and variation in structure and properties of wood. The text then examines lignans and condensed and hydrolyzable tannins. The manuscript takes a look at the alicyclic acid precursors of polyphenols, biosynthesis of polyphenols, and tropolones. Topics include tropolones occurring in wood, polymeric polyphenols, synthesis of pre-aromatic compounds, shikimic acid, and quinic acid. The book then ponders on the influence of extractives on the pulping of wood and the influence of extractives on the color of ground wood and newsprint. The publication is a valuable reference for researchers interested in the processes and methodologies involved in the manufacture of pulp and paper.

Book Description :

This book includes papers on polymeric materials from renewable resources known as `Biorelated Polymers and Plastics', and issues are bound to their utilization and environmental impact in their production, conversions to manufacts and ultimate disposal of post-costume manufacts. Modern industrial developments inspired by the new concepts of sustainability and ecocompatibility require a deeper attention to renewable resources as a new-old source of raw material and feedback. This new trend, occurring not only in industrialized countries but also in emerging countries and countries in transition, thoroughly permeates the polymer and plastic industry, due to the big impact that those materials have on the modern way of life. Plastic waste, specifically that stemming from segments of packaging, containers for solids and liquids and single use items, is attracting much effort from municipality officers, producers and converters, aimed at finding a harmonized solution among the various options available for their appropriate management. In this respect, polymeric materials of natural origin (biopolymers), as well as materials from renewable resources useable for the production of monomeric precursors, or semi-synthetic polymeric materials, constitute a focal point for future industrial development in the production of polymers and plastics. The present book contains much valuable information and scientific hints on a modern approach aimed at designing processes and products with minimal negative environmental impact.

Book Description :

Wood as found in trees and bushes was of primary importance to ancient humans in their struggle to control their environment. Subsequent evolution through the Bronze and Iron Ages up to our present technologically advanced society has hardly diminished the importance of wood. Today, its role as a source of paper products, furniture, building materials, and fuel is still of major significance. Wood consists of a mixture of polymers, often referred to as lignocellulose. The cellulose micro fibrils consist of an immensely strong, linear polymer of glucose. They are associated with smaller, more complex polymers composed of various sugars called hemicelluloses. These polysaccharides are embedded in an amorphous phenylpropane polymer, lignin, creating a remarkably strong com posite structure, the lignocellulosic cell wall. Wood also contains materials that are largely extraneous to this lignocellulosic cell wall. These extracellular substances can range from less than 1070 to about 35% of the dry weight of the wood, but the usual range is 2% -10%. Among these components are the mineral constituents, salts of calcium, potassium, sodium, and other metals, particularly those present in the soil where the tree is growing. Some of the extraneous components of wood are too insoluble to be ex tracted by inert solvents and remain to give extractive-free wood its color; very often these are high-molecular-weight polyphenolics.
