Artist conception highlights electron behavior in a single layer of iron-selenium atoms (red and purple) on a strontium titanate layer (blue pyramid shapes).December 2015Science 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 »

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.December 2015Science 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 »

Short laser pulses (the wide red arrow) on the order of femtoseconds (one quadrillionth of a second) changed the electronic properties of a material (the brown hexagonal shape) by triggering phase transitions.December 2015Science Highlight

Lasers Leave a Mark on Materials - At the Atomic Level

Ultrafast laser shots act like dopants to create new electronic properties in materials. Read More »

Advanced electron microscopy technique permits the simultaneous collection of both signals: secondary electron (that are sensitive to the surface) and transmitted electron.December 2015Science Highlight

Atomic-Level Measurements of Rough Surfaces

Researchers use surface-sensitive signals to atomically resolve the structure of a rough surface. Read More »

Using a scanning electron microscope, the identity of individual elements that make up a single grain of a material can be mapped from the x-rays emitted by the interactions of high energy electrons with the material.December 2015Science Highlight

New Materials Family on the Block

A family of single-phase materials was discovered with coexisting magnetic and electrical properties having potential for electronic applications. Read More »

Scientists devised a new way to wire a photosynthetic protein onto an electrode for integration into devices that turn sunlight into fuel. The light energy collected by the proteins (green) extracts electrons from an electrode (orangey red) through long molecules (yellow) under the proteins.December 2015Science Highlight

How to Wire Photosynthetic Proteins to Electrodes

New approach for connecting light-harvesting proteins enhances the current produced by a factor of four. Read More »

Defects (red and blue markings) surprisingly self-organize in active liquid crystal film of protein filaments and such dynamic reorganization could lead to new approaches for designing self-healing materials.December 2015Science Highlight

Defects Lead to Order

Surprising order found in bundles of protein filaments that move chaotically and form liquid crystals that could led to novel self-healing. Read More »

Whether a solid or liquid forms from charged polymers depends on the “handedness” of the oppositely charged polymer chains.December 2015Science Highlight

Will It Be a Solid or a Liquid? The Molecular Structure Has the Answer

Oppositely charged polymer chains can be “right-handed,” “left-handed,” or have no “handedness” at all, which controls whether a solid or liquid forms. Read More »

Aluminum-ion batteries could rapidly charge - in less than one minute.December 2015Science Highlight

A Step Towards New, Faster-Charging, and Safer Batteries

First prototypes of aluminum-ion batteries charge quickly and have the potential for long lifetimes, low cost, and safe operation. Read More »

A scanning probe microscope (SPM) can detect two similar signals, which could lead to ambiguous identification of ferroelectric materials.December 2015Science Highlight

Ferroelectricity – Ambiguity Clarified, and Resolved

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