Artist conception highlights electron behavior in a single layer of iron-selenium atoms (red and purple) on a strontium titanate layer (blue pyramid shapes).12.14.15Science Highlight

Vibrations Raise the Critical Temperature for Superconductivity

Scientists reveal that coupling between electrons and atomic vibrations play a key role in this vexing phenomenon. Read More »

In an iron-based superconductor, model patterns of electron spins show two competing liquid-like magnetic phases. (Positive spins correspond with yellow and red, while negative spins are green and black.)12.14.15Science Highlight

Magnetic Dance at the Threshold of Superconductivity

Near the onset of superconductivity, continuous exchange of electrons occurs between distinct, liquid-like magnetic phases in an iron-based superconductor. Read More »

X-rays can characterize the motion of atomic-scale defects (for example, dislocations) relative to the morphology of a nanoparticle in the electrode of an operating lithium-ion battery. The dislocations are extra planes of atoms inserted into the atomic lattice.12.14.15Science Highlight

Tracking Hidden Imperfections Inside Operating Lithium-ion Batteries

Penetrating x-rays can image defects and phase changes during battery charging and discharging. Read More »
