for Mac OS X is an application for visualizing and understanding x-ray and neutron powder diffraction patterns: the diffraction "fingerprint" routinely used to identify and characterize crystalline materials. It can be used to compare measured and real diffraction patterns for quick phase identification and detection of impurities. A new interface features a Structures Drawer, into which files and folders can be dropped for rapid cataloging, browsing, etc. Other key features include tools for moving, arranging and customizing individual patterns - and on-the-fly simulation of multi-phase mixtures. It is available for $190 (single-user academic version).
CrystalDiffract is designed to work with CrystalMaker 6, a crystal structures visualization program. Users can display a crystal structure in CrystalMaker, then with a single menu command, display the corresponding x-ray or neutron powder diffraction pattern in CrystalDiffract. The program can also be used as a stand-alone application, reading from CrystalMaker binary files. The company is bundling several with the demo version of CrystalDiffract.
CrystalDiffract 5 is a "Mach-O" application, which is fully-optimized to run natively on Mac OS X 10.2 and later. The free demo version allows users to calculate diffraction patterns for any crystal, simulate x-ray or neutron diffraction, visualize diffraction as films or graphs, measure and index a diffraction profile, and interactively edit structural and other data. The full version also adds the ability to visualize multiple diffraction patterns in the same window, simulate multi-phase mixtures, time-of-flight and energy-dispersive diffraction, compare observed experimental data with simulated data, and more.
