“Frustration” plus a pulse of laser light resulted in a stable “supercrystal” created by a team of researchers led by Penn State and Argonne National Laboratory, together with University of California, Berkeley, and two other national labs.
Under the right conditions, ordinary clear water droplets on a transparent surface can produce brilliant colors, without the addition of inks or dyes. This iridescent effect is due to “structural color,” by which an object generates color simply by the way light interacts with its geometric structure.
Susan Trolier-McKinstry, the Steward S. Flaschen Professor of Ceramic Science and Engineering, Penn State, has been named a member of the National Academy of Engineering (NAE).
Trolier-McKinstry is among the 86 new members and 18 foreign members elected for 2019. The NAE recognized her for "development of thin film multilayer ceramic capacitors and piezoelectric microelectromechanical systems."
A new type of light-emitting diode lightbulb could one day light homes and reduce power bills, according to Penn State researchers who suggest that LEDs made with firefly-mimicking structures could improve efficiency.
