Nanospaced stacking faults improve the strength of magnesium alloys

March 25, 2013 By Leave a Comment
Nano-spaced stacking faults are parallel fault-lines in the structure of the alloy that increase the strength of the material.

Stronger, lightweight magnesium alloys have potential structural applications in the automobile and aerospace industries.

Nanostructured electron source developed at NIST

March 12, 2013 By Leave a Comment
NIST's silicon carbide field emitter produces a flow of electrons comparable to hot sources, but without the need for heat. By dissolving much of the material away to make a porous structure with a large surface area, NIST scientists ensured that as an electron emission point on an individual spike wears out, another is available to take its place, making the array more durable as a whole.

Researchers build a high-efficiency nanostructured electron source that could improve microwave communications and radar.
