The fIrst edition of the Science 0/ Photobiology edited by Kendric C. Smith (plenum Press, 1977) was a comprehensive textbook of photobiology, devoting a chapter to each of the subdisciplines of the fIeld. At the end of many of these chapters there were brief descriptions of simple experiments that students could perform to demonstrate the principles discussed. In the succeeding years some photobiologists felt that a more complete publica tion of experiments in photobiology would be a useful teaching tool. Thus, in the 1980s the American Society for Photobiology (ASP) attempted to produce a laboratory manual in photobiology. Cognizant of these efforts, Kendric Smith elected to publish the se...
Offers a thorough overview of the important agricultural applications of both natural products and synthetic compounds derived from natural products, presenting detailed information on the isolation, structural studies, biological activity and toxicology of these compounds. The expanding area of insecticidal natural products is highlighted.
Electroactive oligomers form an important class of advanced materials for the development of new devices such as thin-film, flexible batteries; semiconductors; large-area optical displays; and sensors. In addition, the study of oligomeric model compounds is an essential prerequisite for understanding and developing polymers for electronics and optoelectronics applications. Written and edited by leading scientists in the field, this applications-oriented handbook represents the first comprehensive, systematic study of electroactive oligomeric materials. Special emphasis is placed on a critical review of the literature; relevant materials and technical data are collected in tables throughout. Includes - materials synthesis - structure--property relationship as a function of chain-length - applications in optics and electronics - oligomers as models for polymers - the role of oligomers in tomorrow's technology? Electronic Materials - The Oligomer Approach offers a stimulating combination of basic concepts and practical applications. It is sure to become a standard reference source that no-one working in the field can do without.
This first concise handbook on this important new class of organic conducting materials gives a broad survey over this emerging field of research. The physical background is covered as well as the synthesis, electronic and nonlinear optical properties and applications of these advanced materials. This information will be of high value for graduate students, researchers and practitioners working in the interdisciplinary field of materials science, polymer and organic chemistry and applied physics.
For millennia, plants and their habitats have been fundamental to the lives of Indigenous Peoples - as sources of food and nutrition, medicines, and technological materials - and central to ceremonial traditions, spiritual beliefs, narratives, and language. While the First Peoples of Canada and other parts of the world have developed deep cultural understandings of plants and their environments, this knowledge is often underrecognized in debates about land rights and title, reconciliation, treaty negotiations, and traditional territories. Plants, People, and Places argues that the time is long past due to recognize and accommodate Indigenous Peoples' relationships with plants and their ecosy...

Echinacea has emerged from the realm of folklore medicine and into the territory of valued and potentially fundamental therapy. While an understanding of the promising medicinal applications of Echinacea is important, knowledge of the herb's chemistry, cultivation, and analytical profiles is equally as significant. Echinacea: The genus Echin
This volume is a compilation of plenary lectures presented at the IOCD/CYTED Symposium held in Panama City, Panama in 1997, and covers different aspects of research into plants from North, South and Central America. The topics treated all revolve around the chemistry, pharmacology, and biology of these plants. The importance of pharmaceuticals derived from plant sources is described, together with the potential of ethnomedicine for providing new leads in the search for bioactive constituents. The biodiversity of the Americas is underlined and an idea is given of the urgency with which the flora must be studied.
Stevia rebaudiana is a remarkable South American plant that has become widely used in certain parts of the world as a natural sweetening agent and dietary supplement. Purified extracts of S. rebaudiana have been used as sweeteners and flavor enhancers in the food industry in Japan for over a quarter of a century, and have been found to be up to 300 times sweeter than sucrose. This comprehensive volume provides reviews on the botany, ethnobotany, and chemical constituents of the genus Stevia and examines the chemical synthesis of such compounds as steviol and stevioside. The perceived safety of these compounds has become somewhat controversial in recent years, and a thorough consideration of ...
This book provides an up-to-date treatment of antioxidant and biocidal compounds mainly from Latin American plants. New antimicrobials, insecticides and antioxidants are compiled in a single source for the first time based on the research and knowledge of several internationally renowned research groups. This book is organized in three sections: Part I provides a general overview and perspectives on antioxidant, medicinal and biocidal plant compounds; Part II provides information on plant antioxidants isolated from a wide range of species; and Part III describes insecticidal, antimicrobial and other biocidal activities based on peptides, phytoecdysteroids, alkaloids, polyphenols, terpenoids and other allelochemicals.
