Argonne scientists announce first room-temperature magnetic skyrmion bubblesJune 12, 2015

Researchers at UCLA and Argonne announced today a new method for creating magnetic skyrmion bubbles at room temperature. The bubbles, a physics phenomenon thought to be an option for more energy-efficient and compact electronics, can be created with simple equipment and common materials.

Mapping Optoelectronic Properties at the Native Length Scale in Lead Halide Perovskites and 2-D MoSe2
Understanding and eventually controlling optoelectronic processes at the native length scale, e.g. deliberately transporting excitonsto predetermined sites where they perform work, will provide the access to a new parameter space for the development of next generation light harvesting materials.

Slip-sliding away: graphene nanoscrolls enable slick surfacesMay 26, 2015

Superlubricity, the near absence of friction, is realized at the engineering scale when graphene patches at a diamond-like carbon (DLC)-silica interface wrap around nanodiamonds, creating nanoscroll-like features, and slide against the DLC/SiO2 surfaces. Friction and wear are the primary modes of energy dissipation in moving mechanical assemblies. The nanoscroll system results in reduced contact areas and a significantly reduced coefficient of friction, with a potential savings in energy cost.

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.”

Argonne X-rays validate quantum magnetism modelMay 20, 2015

Scientists at Argonne and Max Planck Institute for Solid State Research in Stuttgart, Germany have validated a theorized model of quantum magnetism by observing it firsthand in a honeycomb lattice.
