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

Vibrations Raise the Critical Temperature for Superconductivity

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

Aluminum-ion batteries could rapidly charge - in less than one minute.

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.

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.

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.

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.

Tracking Hidden Imperfections Inside Operating Lithium-ion Batteries

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

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

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.

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.

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.

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

Atomic-Level Measurements of Rough Surfaces

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

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.

How to Wire Photosynthetic Proteins to Electrodes

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

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

Ferroelectricity – Ambiguity Clarified, and Resolved

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

Secretion in droplet-embedded gel permits self-repairing behavior.

Damaged Material, Heal Thyself

Internal storage compartments release droplets of “healing” liquid to repair damaged materials.

The width of a graphene nanoribbon determines its electronic properties, but controlling that width at the atomic scale is a challenge.

Legos for the Fabrication of Atomically Precise Electronic Circuits

Pre-designed molecular building blocks provide atomic-level control of the width of graphene nanoribbons.

Reaping Radioisotopes

Researchers harvest long-lived isotopes that are difficult or impossible to acquire otherwise.
