Getting something from nothing sounds like a good deal, so for years scientists have been trying to exploit the tiny amount of energy that arises when objects are brought very close together. Now, a research team including Princeton scientists has found a way to harness a mysterious force of repulsion, which is one aspect of that force.
A new study has modeled a crucial first step in the self-assembly of cellular structures such as drug receptors and other protein complexes, and found that the flexibility of the structures has a dramatic impact on how fast they join together. Understanding self-assembly could help in the design of new materials and medicines.
The stone monuments of Italy's Certosa di Bologna cemetery have stood for more than two centuries as symbols of peace and eternity. But even stone does not last forever. So Enrico Sassoni, a visiting postdoctoral research associate in Princeton's Department of Civil and Environmental Engineering, is working to protect the marble monuments and even make them stronger.
Recent upgrades in imaging and fabrication facilities for atomic-scale research have made these labs among the best in the world and perhaps unique in their "one-stop-shop" combination of analysis and fabrication.
For the past five years, the Princeton Center for Complex Materials has trained more than 120 teachers during a weeklong, hands-on summer immersion program in Princeton's state-of-the-art laboratories.
