The degradable nature of high-performance, wood-based materials is an attractive advantage when considering environmental factors such as sustainability, recycling, and energy/resource conservation. The Handbook of Wood Chemistry and Wood Composites provides an excellent guide to the latest concepts and technologies in wood chemistry and bio-based composites. The book analyzes the chemical composition and physical properties of wood cellulose and its response to natural processes of degradation. It describes safe and effective chemical modifications to strengthen wood against biological, chemical, and mechanical degradation without using toxic, leachable, or corrosive chemicals. Expert researchers provide insightful analyses of the types of chemical modifications applied to polymer cell walls in wood, emphasizing the mechanisms of reaction involved and resulting changes in performance properties. These include modifications that increase water repellency, fire retardancy, and resistance to ultraviolet light, heat, moisture, mold, and other biological organisms. The text also explores modifications that increase mechanical strength, such as lumen fill, monomer polymer penetration, and plasticization. The Handbook of Wood Chemistry and Wood Composites concludes with the latest applications, such as adhesives, geotextiles, and sorbents, and future trends in the use of wood-based composites in terms of sustainable agriculture, biodegradability and recycling, and economics. Incorporating over 30 years of teaching experience, the esteemed editor of this handbook is well-attuned to educational demands as well as industry standards and research trends.
Vols. 39-214 (1874/75-1921/22) have a section 2 containing "Other selected papers"; issued separately, 1923-35, as the institution's Selected engineering papers.
Botanical, a new series from Reaktion, is the first to integrate horticultural writing with a broader account of the cultural and social impact of plants. Oak, one of the first two books in the series, narrates the biography of the tree that since time immemorial has been a symbol of loyalty, strength, generosity, and renewal. Peter Young explores how the oak, native to the northern hemisphere and found in locations as diverse as the Americas and tropical Asia, has played an important role in state-building, art, folk tales, poems, and songs. Starting with the pagan societies that venerated the oak, Young examines how the tree was used in other religions, revealing how it was believed to be a gateway between worlds in Celtic mythology and later became sacred to Thor in Norse mythology. He follows the oak as it was adopted by many Western European countries as a national symbol, including England, France, and Germany. The United States Congress designated the oak as America’s national tree in 2004, and it is the state tree of Iowa, Connecticut, Illinois, Maryland, New Jersey, and Georgia. Individual oak trees have also gained historical importance, such as the Charter Oak in Hartford, Connecticut, which became a symbol of American independence. In addition to tracing the history of the tree itself, Young investigates oak as a wood used to make furniture, bridges, wine casks, homes, ships, weapons, and even the electric chair, and he describes how the tree has been used as a food source—its fruit, the acorn, was eaten in ancient Greece, ancient Iberia, and Korea, and it was a traditional food of Native Americans. Packed with information and beautiful illustrations, Oak tells the fascinating tale of this stately, durable member of the natural world.
