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.

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 This includes unpublished spectra.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 #101. Download 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.

For QuickTime movies of two of the crystallization pathways ("mechanisms")
that Noam has found and described in his
publication (see publication #114), click

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.
