1.  Jonah Erlebacher's really cool (but huge, 93 Meg) movie of dealloying.  This is ongoing work being done in collaboration with Jonah (now at Johns Hopkins), Karl Sieradzki (Arizona State) and Alain Karma (Northeastern) and described in our publication in Nature.  Research description   Download movie (.avi format)

2.  Yuechao Zhao et al.'s Sm:YAG high-T pressure calibration spectra for Diamond Anvil Cells (1.2 Meg).  This includes unpublished spectra. Description in publication #101Download spectra (.zip format)

3.Noam Bernstein's simulation of the atomic structure and motion at the amorphous/crystal interface (which is too large for ab-initio calculations) to find realistic crystallization reaction pathways.
To read the Research Description click here.
For QuickTime movies of two of the crystallization pathways ("mechanisms") that Noam has found and described in his publication (see publication #114), click
      here for the "simple" mechanism (1.5 Meg);
      here for the "complex" mechanism (3.5 Meg).
Two "side" views of a bunch of atoms at and near the interface doing interesting things are shown for each "mechanism".  Three-fold coordinated Si atoms are color-coded red, four-fold (the normal situation) are white, and five-fold are blue.  Note that migration sequences can be described by a "defect" alternating between 3-fold and 5-fold configurations.  This is especially apparent in the "complex" mechanism.  The energy changes and shape changes in the bar graphs in the QuickTime videos are plotted in his publication (see publication #114), and agree remarkably well with values of the activation energy, activation volume, and other components of the activation strain tensor that we have measured in our laboratory.
