The latter, of course, is not even an option when it comes to viewing complex images, such as 2D Fourier transforms or optical wave-field cross-sections!

    This lab began as the UM-StL component of the St. Louis Consortium for Microstructural Studies in the late 1980's, and continues that Consortium's objective of developing and offering advanced techniques for "getting small", and doing microscopic detective work on materials in the size range between microns and atoms. This lab: (i) brought the first scanning probe microscopes (tunneling and force) to the area, (ii) proposed for and then guided the building of a triple bi-story building, the first in Missouri designed from the ground up for atomic-resolution imaging, (iii) organized the first meeting of the MissOuri NanoAlliance (with funds from the governor's research alliance), and (iv) continues to manage the only atom-resolution (sub-2A point to point) transmission electron microscope facility in Missouri. Always part of a regional "Center without Walls", it is also the operating unit of the UM-StL Center for Molecular Electronics' Microstructural Studies Facility most directly linked to present and prospective Industry Sponsorships for the Center.
