The image depicts a nanobiosensor consisting of a carbon nanotube (gray) covalently attached to the coxsackie-adenovirus receptor (magenta). This device detects the adenovirus, one of the viruses responsible for the common cold, when Knob proteins from the virus capsid (orange) bind to the receptor (magenta). These devices were synthesized in Prof. Charlie Johnson's group.
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.
SDSS Galaxy Survey
The UPenn Fit Catalog provides 2-d galaxy profile fits in several visible bands using SDSS data. Additional data collected from other sources is provided to facilitate analysis. The catalog is constructed and maintained by Professor Mariangela Bernardi and her group.
Self-assembling Building Blocks
Self-assembling building blocks occur in a diverse set of supramolecular, macromolecular, and other complex systems that impact numerous fields such as industrial dyes and pigments, xerographic receptors, organic semiconductors, transistors, light-emitting diodes and solar cells. Prof. Paul Heiney collaborates with chemists and material scientists on the study of such molecular systems.
The Best View in Philadelphia
The University of Pennsylvania recently finished their newest addition
to the campus, Penn Park, which adds a brilliant contrast to the
Philadelphia skyline and gives multiple sports teams a new place to
practice and engage in athletics.
The National Institutes of Health have awarded University of Pennsylvania researchers a five-year, $2.8 million grant to further research on techniques for monitoring blood flow in the brain following strokes.
"...As stars began to form, they emitted radiation that ionized these hydrogen atoms, a process which caused the holes to appear. The light that this process produced billions of years ago still exists, and can be used to chart the birth of the first galaxies. But does the technology exist to do so?..."
