An Iridate with Fermi Arcs Print
Wednesday, 29 October 2014 00:00

Researchers have discovered that "Fermi arcs," much-debated features found in the electronic structure of high-temperature superconducting (HTSC) cuprates, can also be found in an iridate (iridium oxide) compound—strontium iridate.

ALS Evidence Confirms Combustion Theory Print
Wednesday, 22 October 2014 11:43

Researchers recently uncovered the first step in the process that transforms gas-phase molecules into solid particles like soot and other carbon-based compounds. It’s a discovery that could help combustion chemists make more efficient, less polluting fuels and help materials scientists fine-tune their carbon nanotubes and graphene sheets for faster, smaller electronics.

Skyrmion Behavior Revealed by Two X-Ray Studies Print
Thursday, 11 September 2014 15:18

Two research groups have recently published separate studies in which soft x-rays reveal how skyrmions—quasiparticles made up of spin vortices—react to external fields. Their work lays the foundation for understanding these fascinating constructs and eventually utilizing them in spintronic applications.

Graphene’s 3D Counterpart Print
Monday, 21 July 2014 08:59

ALS researchers have discovered a material that is essentially a 3D version of graphene—the 2D sheets of carbon through which electrons race at many times the speed at which they move through silicon. The discovery promises exciting new things to come for the high-­tech industry, including much faster transistors and far more compact hard drives.
