Analytic approaches
To see some of our analytical tools in action, in a pedagogical context, you might check page here about javascript electron-optics as well as our unknown nanostructure explorer on the web. They are still in draft form and although they may also work on mobile devices, most such devices may not have the computing power for real-time interaction.
The subpage-links below, as well as on the navigation panel at left, will take you to what we have up here so far. The slides below (which have evolving notes if you view them on google drive by hitting the Open TEMdataAnalysis3 button below) are from a presentation on emergent data analysis strategies at the PREMIER Network's second (2014 May 27-28) Advances in Structural and Chemical Imaging meeting, in this case held at the University of Washington in Seattle.
This section is to provide an overview, some practical example applications, and some literature references of several approaches to experimental data analysis for which this group can offer some tools. One underlying theme is letting specimens speak for themselves in robust ways that are useful now and may be more useful with better-informed models downstream. Tools to this end include digital-darkfield tableaus, nano-particle plots of single/cross-fringe ratio versus the no-fringe fraction as well as fringe-angle versus projected-distance from the symmetry-axis of the nano-tube on which they lie, and pixel maps of the incident-electron fraction-undetected versus fraction with zero energy-loss.
Some of the types of data that we try to analyze here are contained in the image at right, of 100-atom platinum-particles on single-strand DNA wrapped around (few and) single-walled carbon-nanotubes, wet-mounted on a 100Å = 10nm thick holey-carbon film (right side) in turn suspended across a 3mm diameter copper transmission-electron-microscope (TEM) grid, and recorded using 300 keV electrons (wavelength ~2pm) with a TEM whose point-resolution is just under 2Å = 200pm.
