A link to our JS/HTML5 TEM simulator* is on our google electron-detectives site here.

A special version has been set up to examine various forms of disordered carbon on-line. Can YOU tell which unknown contains faceted nanocones?

ImageJ Routines Under Development

Check our digital darkfield page for the latest information on these. In addition to digital darkfield routines for mapping periodicites and sub-pixel lattice spacing changes across an image, routines of interest cover things like projected potential from atom positions; strong phase object HREM from projected potential; Log-Log roughness spectra of topographic images; azimuthal averaging w/offset analysis; contact-mode AFM/LFM/LDM image simulation; single crystal and powder electron diffraction simulation/indexing; and fringe-visibility/Kikuchi band plots.

Mathematica 6+ Routines Under Development

These should be possible to test with Wolfram's free Mathematica Player. Since they are still in a development phase, critical feedback on them would be most welcome.

Some even more ancient (much less than 64 bit) program resources may be found here.
