Low-cost solar-powered water filter, inspired by pufferfish, removes lead and other contaminants
A new device that purifies water relying only on sunlight could help produce clean drinking water at low cost and little environmental impact. When placed in contaminated water, the gel soaks up only pure water, leaving contaminants behind. When sunlight warms the gel, it change shapes and expels the water for collection.
Graduate School honors Ph.D. student Christopher Browne for work on water and energy problems
The Graduate School has awarded Christopher A. Browne a Wallace Memorial Fellowship in Engineering, funding his Ph.D. work for the 2021-2022 academic year.
Princeton technology could improve COVID-19 vaccines
A new technology being developed by Princeton University researchers and alumni could offer a more effective and robust delivery method for COVID-19 vaccines.
From lab to everyday life: Princeton accelerator fund supports promising innovations
Three technologies emerging from CBE that address some of society’s biggest challenges — from transparent solar cells to low-cost water purification — will receive support for research and development through Princeton’s Intellectual Property Accelerator Fund.
Researchers grow hair with this clever physics trick
A team of Princeton researchers found they could coat a liquid elastic on the outside of a disc and spin it to form useful, complex patterns. When spun just right, tiny spindles rise from the material as it cures. The spindles grow as the disc accelerates, forming a soft solid that resembles hairs.
"See-through soil" could help farmers deal with future drought

In research that may eventually help crops survive drought, scientists at Princeton University have uncovered a key reason that mixing material called hydrogels with soil has sometimes proven disappointing for farmers.

Hydrogel beads, tiny plastic blobs that can absorb a thousand times their weight in water…

Cell mapping expert receives HHMI diversity fellowship with eight years of support
The Howard Hughes Medical Institute (HHMI) has named Princeton postdoctoral researcher Sofia Quinodoz a 2020 Hanna Gray Fellow, bolstering her study into how the structures within cells contribute to disease.
Dewdrops on a spiderweb reveal the physics behind cell structures

As any cook knows, some liquids mix well with each other, but others do not.

For example, when a tablespoon of vinegar is poured into water, a brief stir suffices to thoroughly combine the two liquids. However, a tablespoon of oil poured into water will coalesce into droplets that no amount of stirring can dissolve. The…

Postdoc Susan Leggett awarded fellowship to study aggressive cancer
Susan Leggett, a postdoctoral research associate in chemical and biological engineering, has received a two-year fellowship from the New Jersey Alliance for Clinical and Translational Science (NJ ACTS), supporting her research into an especially aggressive form of cancer and connecting her with a network of advanced researchers beyond Princeton.
Cliff Brangwynne upends tradition to establish a new view of biology
Brangwynne suspected that his two interests, biology and materials science, were more connected than his coursework suggested.
