Slip sliding away: Graphene and diamonds prove a slippery combinationMay 22, 2015

Scientists at the U.S. Department of Energy’s Argonne National Laboratory have found a way to use tiny diamonds and graphene to give friction the slip, creating a new material combination that demonstrates the rare phenomenon of “superlubricity.”

Unraveling the origin of the pseudogap in a charge density wave compoundApril 1, 2015

By combining a variety of different experimental techniques and theory, a group led by researchers at Argonne obtained unique insights into the nature of the pseudogap state in a canonical charge density wave material.

Modeling how cells move together could inspire self-healing materialsMarch 18, 2015

A paper published in Nature’s Scientific Reports by a team led by Argonne physicist Igor Aronson modeled the motion of cells moving together. This may help scientists design new technologies inspired by nature, such as self-healing materials in batteries and other devices.

Shape-shifting groups of nanorods release heat differentlyFebruary 18, 2015

Researchers at Argonne have revealed previously unobserved behaviors that show how the transfer of heat at the nanoscale causes nanoparticles to change shape in groups.
