Sounds of Atoms: Life in Science

Author(s)
Stephan J. Stranick
Early in setting up our nanoscience laboratory at Penn State, we were frustrated because we could not peer into the tunneling junctions of our scanning

Centrifugal Length Separation of Carbon Nanotubes

Author(s)
Jeffrey A. Fagan, Matthew Becker, Jae H. Chun, Barry J. Bauer, Jeffrey R. Simpson, Angela R. Hight Walker, Erik K. Hobbie
Separation of single wall carbon nanotubes (SWCNTs) by length via centrifugation in a high density medium, and the characterization of both the separated

Modulus and Chemical Mapping of Multi-layer Coatings

Author(s)
Aaron M. Forster, Chris A. Michaels, Li Piin Sung, Justin Lucas
Thermoplastic olefins (TPO) are polymeric materials utilized for interior and exterior automotive parts. These materials are often painted to enhance appearance

Superfludity and phase transitions in a resonant Bose gas

Author(s)
Leo Radzihovsky, Peter B. Weichman, Jae Park
The atomic Bose gas is studied across a Feshbach resonance, mapping out its phase diagram, and computing its thermodynamics and excitation spectra. It is shown

Hollow spherical supramolecular dendrimers
