The new official web page for the UM-StL Center for Nanoscience
may now be found here.
Renamings at UM-StL in the April 2007 time frame:
Center for Molecular Electronics (CME) will be changing to Center
for Nano Science (CNS), and Scanned Tip and Electron Image Lab will be changing to
Microscope Image and Spectroscopy Tech Lab (MIST).
If you are a CME collaborator, consider applying for access to the
Center's new technical discussion and networking newsgroup.

Nature photography on the nanoscale:
Although these may look like an
artist's conception of glaciers on Europa, this is data from the real world. Moreover, one can physically interact with the real molecule-high objects of choice in the image, to rearrange them and then see how they respond!
Figure: Unexpected slippery patches (white) less than a nanometer high, seen from
a nanohuman viewpoint in this atomic force microscope image of freshly cleaved & etched mica.
The peaks are particles lying on the mica surface. Coloration is
provided by lateral force measurements during the scan, where darker means stronger forces opposing the scan.
The larger image (click above) also shows nanometer
high mica-layer steps, leading down into an etched nuclear-particle track pit, and a scan-line noise ripple in the foreground.

On 29 July 1997, a meeting of the Missouri-wide
Silicon River Consortium
including state/regional representatives, participants from the University of Missouri
and all campuses plus Washington & St. Louis Universities, and participants
from existing and prospective Missouri-based micro-electronic and
information-technology corporations, was held in the new CME building conference area.

The UM-StL Center for Molecular Electronics began with concurrent
NSF
Center for Science and Technology Proposals written in 1988, one by Chemistry and
Physics Researchers at UM-St. Louis and the second by St. Louis Consortium for
Microstructural Studies researchers at Monsanto
and Washington University. These
two threads were brought together via program inititiatives by then Chancellor
Marguerite Barnett and the Physics Department,
in the process establishing the Scanned Tip and Electron Image Lab at UM-StL. Continued initiative by Chemistry Professor Tom Jones, along with active support by Congressman William Clay, resulted in a DOE grant of $10M for research equipment and the CME Building now under construction. Day-to-day funding of Center operations, through industrial sponsorships as well as Federal and State Grants, continues to rely on long-standing and burgeoning collaborations between researchers with the initiative to pool resources between institutions toward solving problems neither institution can solve alone.
