Three pairs of diffuse magnetic x-ray scattering intensities arising from three short-range zigzag states (illustrated at the center) in a honeycomb lattice iridate Na2IrO3. Distinct magnetic anisotropy of each state manifests bond-directional interactions that lead to a strong magnetic frustration. (Click image to enlarge.)
Argonne X-rays validate quantum magnetism model

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.

Shedding new light on LEDs

LEDs, or light-emitting diodes, are the secret behind your iPhone screen, flatscreen TVs, Christmas lights and crosswalk signals. They can last longer and save more energy than traditional incandescent bulbs. But there is one thing they aren’t very good at: efficiently emitting light in the yellow-green spectrum.
