Phasing out a microscope's tricks

An instrument error can lead to complete misidentification of certain crystals, reports a KAUST study that suggests researchers need to exercise caution when using electron microscopes to probe two-dimensional (2-D) semiconductors.

Why shaving dulls even the sharpest of razors

Razors, scalpels, and knives are commonly made from stainless steel, honed to a razor-sharp edge and coated with even harder materials such as diamond-like carbon. However, knives require regular sharpening, while razors ...

Unlocking the gate to the millisecond CT

Many will undergo a CT scan at some point in their lifetime—being slid in and out of a tunnel as a large machine rotates around. X-ray computed tomography, better known by its acronym CT, is a widely used method of obtaining ...

Engineers open door to big new library of tiny nanoparticles

The development of bimetallic nanoparticles (i.e., tiny particles composed of two different metals that exhibit several new and improved properties) represents a novel area of research with a wide range of potential applications. ...
