Penn: Nanoplasmonic ‘Whispering Gallery’ Breaks Emission Time Record in Semiconductors

PHILADELPHIA — Renaissance architects demonstrated their understanding of geometry and physics when they built whispering galleries into their cathedrals. These circular chambers were designed to amplify and direct sound waves so that, when standing in the right spot, a whisper could be heard from across the room. Now, scientists at the University of Pennsylvania have applied the same principle on the nanoscale to drastically reduce emission lifetime, a key property of semiconductors, which can lead to the development of new ultrafast photonic devices.

Penn Researchers Show Single Drug and Soft Environment Can Increase Platelet Production

PHILADELPHIA — Humans produce billions of clot-forming platelets every day, but there are times when there aren’t enough of them, such as with certain diseases or during invasive surgery. Now, University of Pennsylvania researchers have demonstrated that a single drug can induce bone marrow cells called megakaryocytes to quadruple the number of platelets they produce.

Penn Researchers Break Light-Matter Coupling Strength Limit in Nanoscale Semiconductors

PHILADELPHIA—New engineering research at the University of Pennsylvania demonstrates that polaritons have increased coupling strength when confined to nanoscale semiconductors. This represents a promising advance in the field of photonics: smaller and faster circuits that use light rather than electricity.
