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 »

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 »

A scanning probe microscope (SPM) can detect two similar signals, which could lead to ambiguous identification of ferroelectric materials.12.14.15Science Highlight

Ferroelectricity – Ambiguity Clarified, and Resolved

Novel technique accurately distinguishes rare material property linked to improving sensors and computers. Read More »

Advanced electron microscopy technique permits the simultaneous collection of both signals: secondary electron (that are sensitive to the surface) and transmitted electron.12.14.15Science Highlight

Atomic-Level Measurements of Rough Surfaces

One Photon or Two?

First mixed matter/anti-matter probe aims to solve decade-old proton puzzle. Read More »

A stripe-shaped magnetic region (domain), shown in blue (top left) in an ultrathin film device (orange structure). The narrowing region of the device causes the current distribution to change (two of the three red arrows change direction), leading to the breakdown of the magnetic domain into circular disk-shaped bubbles, called skyrmions (bottom left) Magnetic skyrmion bubbles (bottom right) were experimentally observed using magnetic imaging.11.01.15Science Highlight

Creating Novel Magnetic Islands for Spintronics

Generating and moving small, stable magnetic islands at room temperature could be the ticket to more energy-efficient electronics. Read More »
