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 at MIT have found a way to make graphene with fewer wrinkles, and to iron out the wrinkles that do appear. They found each wafer exhibited uniform performance, meaning that electrons flowed freely across each wafer, at similar speeds, even across previously wrinkled regions.

Researchers “iron out” graphene’s wrinkles

New technique produces highly conductive graphene wafers.

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.

These scanning electron microscope images show the sequence of fabrication of fine lines by the team's new method. First, an array of lines is produced by a conventional electron beam process (top). The addition of a block copolymer material and a topcoat result in a quadrupling of the number of lines (center). Then the topcoat is etched away, leaving the new pattern of fine lines exposed (bottom)...

A big leap toward tinier lines

Self-assembly technique could lead to long-awaited, simple method for making smaller microchip patterns.

MIT aerospace researchers have demonstrated that some randomness in the arrangement of carbon atoms makes materials that are lighter and stronger, shown at lower right in illustration, compared to a more densely packed and tightly ordered structure, shown lower left. They formed a type of disordered graphite-like carbon material that is often called glassy carbon by “baking” a phenol-formadehy...

Disorder can be good

Researchers discover that chaos makes carbon materials lighter and stronger.

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.
