With Ohio Supercomputer Center access, Sadhan Jana at the University of Akron simulated the equilibrium state of organization of 12 organic tie-molecules on the surface of MWCNT. The red dots represent oxygen, white represent hydrogen, and gray represent carbon atoms in tie molecules.

About the TEAM Project:
In December 1959, physicist Richard Feynman presented his famous lecture “There’s Plenty of Room at the Bottom”, now seen by many as the founding vision for nanoscience.
When he spoke about electron microscopy, Feynman posed this challenge: “The electron microscope is not quite good enough, with the greatest care and effort, it can only resolve about 10 angstroms … Is there no way to make the electron microscope more powerful?”
In 2009, exactly 50 years later, a group of scientists will meet the Feynman challenge with delivery of the TEAM microscope, an instrument to provide unprecedented opportunities to observe atomic scale order, electronic structure and dynamics of individual nanostructures.
Engineering researchers have discovered that under the right circumstances, basic atomic forces can be exploited to enable nanoparticles to assemble into superclusters that are uniform in size and share attributes with viruses.
