News: Complex Materials and Processing

Shih’s thesis focused on specially formulated chain-like molecules called polymers that can help flush contaminants from hard-to-reach crevices in underground aquifers. How these polymers move through porous rocks to dislodge pollutants — and why they are more effective in some settings than in others — is not well understood.
Cleaning up groundwater is no small job, but a team of Princeton researchers is on a mission to make it simpler — using microscopic springs.
Water balloons may seem like a trivial matter. A toy for mischievous kids in summer. But for scientists, the behavior of balls of liquid wrapped in a thin elastic membrane is critical to everything from understanding blood cells to fighting fires.
