Penn Engineering’s Robert Carpick, Cangyu Qu, and Lu Fang have developed a theoretical model that overcomes previous challenges in accurately describing the relationship between mechanical stress and chemical reactions. Their new study fills in the gap for describing the forces that occur when molecules are squeezed between two surfaces. This result helps make it easier to predict mechanochemical reactions, which are promising for the green manufacturing of plastics, metallic compounds, lubricants and more.
When the Schuylkill swallowed the city: Lessons from Hurricane Ida’s historic flood
New Penn research shows that Hurricane Ida wasn’t a once-in-a-century anomaly but a preview of how climate change, urbanization, and aging infrastructure are rewriting flood risk.
The Fed explained: What it does and why it matters
Former Philadelphia Fed President Patrick Harker and financial historian Peter Conti-Brown, both Wharton professors, unpack the central bank’s origins, its unusual structure, and the quiet ways it shapes the economy
How population changes are impacting primary education worldwide
Research from Penn sociologist Emily Hannum and colleagues reveals regional trends in whether school-age populations are increasing, plateauing, or decreasing—and shows how different countries are responding.
A bioengineered bean gum from the lab of Penn Dental’s Henry Daniell is found to reduce the levels of three microbes associated with head and neck squamous cell cancer to almost zero, without affecting the beneficial bacteria normally found in the mouth.
Fighting oral cancer with bioengineered chewing gum
Research led by Penn Dental’s Henry Daniell shows that antiviral and antibacterial chewing gums reduce the levels of three microbes linked to worse outcomes in oral cancers, paving the way for more effective and affordable therapies.
