This book covers the full spectrum of activity in the GaN and related materials arena. These semiconductors are finding applications in full-color displays, high-density information storage, white lighting for outdoor or backlit displays, solar-blind UV detectors, high-power/high-temperature electronics, and covert undersea communications. Progress is been reported in the growth of thick layers on patterned substrates by various methods, leading to lower overall defect concentrations and improved current-voltage and reliability characteristics. The rapidly increasing market for blue/green LEDs is also noted by the entry of a number of new companies to the field. While these emitter technologies continue to be dominated by MOCVD material, there are exciting reports of UV detectors and HFET structures grown by MBE with device performance at least as good as by MOCVD. Topics include: GaN electronic and photonic devices; laser diodes and spectroscopy; electronic devices and processing; quantum dots and processing; novel growth, doping and processing and rare-earth doping and optical emission.

Bridging the fields of conservation, art history, and museum curating, this volume contains the principal papers from an international symposium titled "Historical Painting Techniques, Materials, and Studio Practice" at the University of Leiden in Amsterdam, Netherlands, from June 26 to 29, 1995. The symposium—designed for art historians, conservators, conservation scientists, and museum curators worldwide—was organized by the Department of Art History at the University of Leiden and the Art History Department of the Central Research Laboratory for Objects of Art and Science in Amsterdam. Twenty-five contributors representing museums and conservation institutions throughout the world provide recent research on historical painting techniques, including wall painting and polychrome sculpture. Topics cover the latest art historical research and scientific analyses of original techniques and materials, as well as historical sources, such as medieval treatises and descriptions of painting techniques in historical literature. Chapters include the painting methods of Rembrandt and Vermeer, Dutch 17th-century landscape painting, wall paintings in English churches, Chinese paintings on paper and canvas, and Tibetan thangkas. Color plates and black-and-white photographs illustrate works from the Middle Ages to the 20th century.

The idea of The Fingerprint Sourcebook originated during a meeting in April 2002. Individuals representing the fingerprint, academic, and scientific communities met in Chicago, Illinois, for a day and a half to discuss the state of fingerprint identification with a view toward the challenges raised by Daubert issues. The meeting was a joint project between the International Association for Identification (IAI) and West Virginia University (WVU). One recommendation that came out of that meeting was a suggestion to create a sourcebook for friction ridge examiners, that is, a single source of researched information regarding the subject. This sourcebook would provide educational, training, and research information for the international scientific community.
