Trapping nanoparticles with optical tweezers

By exploiting a particular property of light diffraction at the interface between a glass and a liquid, researchers have demonstrated the first optical tweezers capable of trapping nanoscale particles.

Nanoparticle jamming at the water-oil interface

The online cover of Science Advances this week features the assembly of nanoparticle surfactants at a solid-liquid interface using advanced microscopy techniques such as laser scanning confocal microscopy and atomic force ...

Humans ignite almost every wildfire that threatens homes

Summer and fall are wildfire season across the western U.S. In recent years, wildfires have destroyed thousands of homes, forced hundreds of thousands of people to evacuate and exposed tens of millions to harmful smoke.
