A synthetic peptide candidate that can be used for single molecule electronic measurements. Single molecules can act as a functioning part of a field effect transistor device as studied in Professor Charlie Johnson's lab.
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.
MicroRNA and Nanopores
Dr. Meni Wanunu, Prof. Marija Drndic and others at Penn have used solid state nanopores to study microRNA. Target microRNA strands (blue) from living tissue are hybridized with a probe RNA sequence (red). These RNA duplexes are then collected by magnetic beads (orange) that are coated with a p19 protein (green). The RNA duplexes are then removed from the proteins and delivered to the nanopore.
High-Bay Space at DRL
This cube-shaped building sits just east of DRL. The high-bay provides faculty and students a facility for research, fabrication, and telescope display. The building has a 42 foot high ceiling, exposed structural steel framing, and a crane beam and glass sliding doors for moving large telescopes in and out. It was completed in January 2012.
Singh Center for Nanotechnology
The newly-opened (Oct. 4, 2013) 78,000 square-foot Krishna P. Singh Center for Nanotechnology serves as Penn's focal point for nanoscience research and technology-development. P&A's Prof. Jay Kikkawa was instrumental in the planning and provision of vital services for the new facility.
This work, "Lassoing saddle splay and the
geometrical control of topological defects," was done with postdoctoral
fellow Max Lavrentovich. The two work with Professors Randy Kamien
(Physics and Astronomy) and Kate Stebe (Chemical and Biomolecular Engineering).
