Penn Receives $1.5 Million Grant to Predict Sea-Level Rise and Flooding from Hurricanes

PHILADELPHIA — In an effort to better understand sea-level rise and flooding from hurricanes along the Atlantic and Gulf coasts, the National Oceanic and Atmospheric Administration has awarded a three-year, $1.5 million grant to a research team led by the University of Pennsylvania’s Benjamin Horton. The study aims to provide predictive models and reports that can be used both by environmental scientists and coastal communities.

Penn Physicists Develop New Insight Into How Disordered Solids Deform

PHILADELPHIA — In solid materials with regular atomic structures, figuring out weak points where the material will break under stress is relatively easy. But for disordered solids, like glass or sand, their disordered nature makes such predictions much more daunting tasks.

Penn Molecular Scientists Develop Color-Changing Stress Sensor

PHILADELPHIA — It is helpful — even life-saving — to have a warning sign before a structural system fails, but, when the system is only a few nanometers in size, having a sign that’s easy to read is a challenge.  Now, thanks to a clever bit of molecular design by University of Pennsylvania and Duke University bioengineers and chemists, such warning can come in the form of a simple color change.   

Penn Physicists Conquer the ‘Coffee Ring Effect’

A team of Penn physicists have figured out how to conquer the “coffee ring effect”—that “O”-shaped stain of particles that is always left over after coffee drops evaporate — by changing the shape of the particles. The discovery provides engineers with a new set of tools that could have implications in various industrial settings, particularly printing and painting.
