Researchers may have determined why fairly brittle electrode materials in batteries don’t crack under the strain of expansion and contraction cycles when they are used and recharged.

How some battery materials expand without cracking

Brittle electrodes handle expansion by going glassy, study shows.

Researchers have found a way to make tiny particles that can be injected into the body, where they emit short-wave infrared light. The advance may open up a new way of making detailed images of internal body structures such as fine networks of blood vessels.

Nanoparticles open new window for biological imaging

“Quantum dots” that emit infrared light enable highly detailed images of internal body structures.

Researchers have developed a rubber-like fiber, shown here, that can flex and stretch while simultaneously delivering both optical impulses, for optoelectronic stimulation, and electrical connections, for stimulation and monitoring.

Stretching the boundaries of neural implants

Rubbery, multifunctional fibers could be used to study spinal cord neurons and potentially restore function.

Researchers have developed a type of steel with three characteristics that help it resist microcracks that lead to fatigue failure: a layered nanostructure, a mixture of microstructural phases with different degrees of hardness, and a metastable composition. They compared samples of metal with just one or two of these key attributes (top left, top right, and bottom left) and with all three (bottom...

Conquering metal fatigue

Novel laminated nanostructure gives steel bone-like resistance to fracturing under repeated stress.

Mild heating of graphene oxide sheets makes it possible to bond particular compounds to the sheets’ surface, a new study shows. These compounds in turn select and bond with specific molecules of interest, including DNA and proteins, or even whole cells. In this image the treated graphene oxide on the right is nearly twice as efficient at capturing cells as the untreated material on the left.

Graphene sheets capture cells efficiently

New method could enable pinpoint diagnostics on individual blood cells.

This high-resolution transmission electron micrograph of particles made by the research team shows the particles’ highly uniform size and shape. These are iron oxide particles just 3 nanometers across, coated with a zwitterion layer. Their small size means they can easily be cleared through the kidneys after injection.

A new contrast agent for MRI

New iron oxide nanoparticles could help avoid a rare side effect caused by current contrast agents.
