To use the jPOWD applet, your browser must have the JAVA Virtual Machine (JVM) enabled. The jpowdjpx.jar© MDI, Inc. is a web browser JAVA applet that can be integrated into web pages and uses .jpx files from jPOWD program for viewing crystallographic structure data in .jpx format.
| jPOWD Applet |
Click on mineral name in the Index of Mineral Structures for a large interactive display (jpowdjpx.jar Applet) of the chemical structure. This applet requires Java and Specifically the SUN Java Virtual Machine installed/enabled on the client browser. If you have Java installed but no crystal structure appears in the window on the left, you probably have the obsolete MicroSoft Java Virtual Machine installed on your computer. See www.java.com for the proper Java plug-in required to view the interactive structural data. Follow this link for a discussion on mineral structures. |
Warning: This applet runs in your browser (client side application) and is very compute intensive. It may not run on older computers.
Major new addition to Webmineral. View interactive crystal structure diagrams using jPOWD Applet. This applet is replacing the jMOL applet because it is smaller in size and it specializes in mineral and material structure files. The structure files are now integrated-with and viewable-by the species pages for each mineral that has published structural data.
jPOWD from Materials Data, Inc. generates x-ray pattern and structure simulation 'by reading crystallographic structure files, such as *.cif and generates a simulated x-ray diffraction pattern from the atomic positions. The output of binary crystal files (*.jpx) from the jPOWD program and the jpowdjpx applet allows web display of crystal structures.
Mineral Structures - Thanks to the tireless effort of Dr Robert Downs and his associates at the University of Arizona for their crystal structure database. This database contains every structure ever published in the American Mineralogist, The Canadian Mineralogist, European Journal of Mineralogy and Physics and Chemistry of Minerals as well as other selected journals. These structure files contain over 12,000 entries. All of them have been downloaded, converted to .jpx files, and uploaded to webmineral.com.Help file image instructions for jpowdjpx.jar.
There are some caveats to mention. These are:
All binary crystal structure files (.jpx) on this website are the property of Webmineral.com. The applet used for the web display of those structure files (jpowdjpx.jar) is copyrighted by Materials Data, Inc and is used with permission on webmineral.com.
In keeping with the "fair use" copyright doctrine, webmineral will allow the reproduction of a limited number of .jpx files from this website for educational use as long as credit is given to webmineral.com as the source of the .jpx files and credit is given to Materials Data, Inc. for the jpowdjpx.jar file.
Any other use (no citation given, large numbers of files being reproduced, commercial work, etc.) will be considered an infringement of copyright if prior arrangements have not been made with webmineral.com or Materials Data, Inc.
