Researchers designed and synthesized an organic molecule whose electronic structure helps funnel energy into fluorescent emission.

Gaskets and other seals can stop leaks even if the leak-preventing surfaces have just 42 percent of their area in contact at the microscopic scale, according to computer simulations.

Simulations reveal both solid- and liquidlike frictional properties in molecularly thin lubricants.

A rapidly expanding and collapsing microbubble in a fluid exerts forces strong enough to roll submerged particles stuck to a solid surface, which may explain how ultrasonic cleaning of jewelry and silicon wafers in a liquid removes dirt.

Inherently imperfect nanotech components might work together to make a useful product.

In the first quantitative study of the jamming of grain hoppers, a team derived a mathematical model that could lead to improved hopper designs.
