Dipole magnets at the Large Hadron Collider

Protons at the LHC are accelerated to 7 TeV (the equivalent energy to an electron subjected to the potential of more than 4.5 trillion batteries laid end-to-end).  To circulate such powerful beams of particles, the LHC employs superconducting dipole magnets like those shown to provide a magnetic field almost 100,000 times stronger than the earth's magnetic field.


Topology and Liquid Crystals

Liquid crystal molecules can be molded into shapes which resemble a Hopf fibration, a complex shape from topology resembling a series of linked rings wrapped into a torus. This fascinating shape has applications in mathematics, quantum physics, and computer graphics.

From the lab of Bryan Gin-Ge Chen, former grad student of Prof. Randy Kamien.


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.


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.


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.
