Premelting of Colloidal Crystals

Premelting is the localized loss of crystalline order at surfaces and defects at temperatures below the melting transition.  This result is from the lab of Prof. Arjun Yodh.

 

NMDA

Professor Bob Hollebeek was the technical lead for the National Library of Medicine sponsored National Digital Mammography Archive, which provides distributed grid systems for medical storage and records handling.  Parallel and distributed computing approaches apply to the analysis of data from many fields including medical, scientific, social, and economic data.

 

Protein Design

Penn researchers including Penn physicists Marija Drndic and Jay Kikkawa have designed  specialized protein molecules that organize around carbon nanotubes into an atomistically-predefined pattern. Targeted design of such self-organization is a powerful tool for engineering at the nano scale. 

 

Outreach Effort for Penn Physics and Astronomy

At the Penn Summer Science Academy (PSSA) students listen to a lecture, delivered from CERN by Professor Elliot Lipeles, on the discovery of a Higgs-like particle the day after the international announcement.

 

Vector Bundles on Calabi-Yau Manifolds

Supersymmetric vacua of the heterotic string and M-theory are explored through the study of complex algebraic geometry.  The figure is from a recent paper by Prof. Burt Ovrut and collaborators on the Kahler cone substructure associated with the SU(2) bundle for different Kahler moduli.
