Particle size analysis
TOOLS & TECHNIQUES UPDATE
Two million articles ScienceDirect® announces two million articles are now live on its platform for scientific, technical, and medical information. This milestone has been passed as ScienceDirect continues to build a comprehensive research resource, offering immediate access to abstracts, journal, and reference work articles. The two million articles from over 1200 journals are available on-line, alongside a growing number of backfiles and access to bibliographic databases. Contact: www.sciencedirect.com

Cracking ceramics Fracture Mechanics of Ceramics, Volume 13 consists of the Proceedings of the 7th International Symposium on the fracture mechanics of ceramics, which was held in Moscow in July 1999. Edited by R.C. Bradt, D. Munz, M. Sakai, V. Shevchenko, and K.W. White, the latest series volume focuses on environmental effects in fracture and crackmicrostructure interactions in advanced ceramics. Novel methods for testing the mechanics of fracture and standardization are also included.

Properties of materials The Physics and Chemistry of Materials by Joel I. Gersten and Frederick W. Smith provides a comprehensive introduction to the structure and properties of materials. Beginning with the fundamentals of local chemical bonding and atomic order, the book emphasizes the physical and chemical origins of material properties. The use and development of technologically important materials is included, along with a section on synthesis and processing. Intended for use in advanced materials courses, and as a reference for scientists and engineers, the book is complemented by web-based supplementary material, problems, and illustrations. Publisher: John Wiley & Sons, Ltd. ISBN: 0-471-05794-0 Publication: July 2001 Hardback, pp. 856 Price: £81.50 / $110 / 129.50
