  540 Chemistry and allied sciences

Chemistry (BUBL)
Chemistry (Yahoo)
Chemistry (WWWVL)
Internet chemistry resources (Rensselaer Polytech.) - very comprehensive resources, classified by type (e.g. software) and subject. Look especially at "teaching"
World Lecture Hall - CHEMISTRY section (Univ. of Austin Texas) - a collection of university courses from around the world, organised by subject. In some cases actual lecture notes, images etc are provided online, often in concise form. Can be very useful aid to the student .
Web Elements (Mark Winter, Univ. of Sheffield, UK) - online interactive Periodic Table.

• 548 Crystallography

  Crystallography (WWWVL) - distr. from Geneva
  

  • 548.3 Chemical crystallography
    Crystal structure (John C Russ, N Carolina S. Univ.) - this is part of their Visualizations in Materials Science online interactive courseware. Deals with atomic arrangements, coordinate systems, interstitial sites, ionic crystals,covalent crystals and other materials . Quicktime movies of crystal structures.
  • Minerals by Chemical Compostion (David Barthelmy ) - an interactive Periodic table which gives the names and information about minerals which contain the element.

• 548.8 Physical and structural crystallography
  
  • 548.81 Structural crystallography
    Making Matter - The atomic structure of materials (Hewatt-Institut Laue Langevin, Grenoble, Sviss) - account of structural crystallography building to large extent on VRML images.  Stunning and effective 3-D realism.  You will need Cosmo Player for this.  Nothing will increase your understanding of crystal structure as well as this.

    Silicate Structure Types (Kurt L. Bartelmehs, Univ. of Texas) - very useful one page summary of the main silicate classes, with quick loading structural images (including sylised tetrahedral type).  You won´t get a faster, clearer account than this.

    Surface explorer - a WWW oriented tool to display netplanes and surfaces in crystal lattices from Fritz Rammer (FHI)

• 549 Mineralogy (see also 553.8)
  ATHENA - Mineralogy (Pierre Perroud) - comprehensive pages on all aspects of mineralogy.   Includes searchable database of mineral names and a very good image collection.

  The Mineral Gallery (Amethyst Galleries Inc.)- mineral descriptions, images and specimens. The minerals are arranged by class and/or alphabetically. Additional information also.
  The Natural History Museum - MINERALOGY (UK) - brief but useful explanations online of a few projects: caves, Electron microscopy + analysis, environmental minerals, meteorites and black smokers (ocean ridge hydrothermal minerals).
  Smithsonian Institute mineral collection. - thumbnail pictures and short descriptions of the chief minerals, arranged by type. The thumbnails open to larger format high quality pictures.
