Under the cover of darkness, a well-known brittle semiconductor turns out to be surprisingly flexible. Scientists at a Japanese university have investigated the previously unknown ability of zinc sulfide crystals to resist deformation under irradiation by light and to bend when the light goes out  (Science, doi:10.1126/science.aar6035). Illumination experiments Inorganic semiconductors play an important role in […]

Imagine the Sun’s surface as an utterly black sphere. Imagine a cloudscape above this that is comprised of colorful fans of glowing wisps of translucent fog, all vastly larger than the Earth, which are continually swaying and pulsing, occasionally being torn apart by lightning storms of literally astronomical proportions. Difficult? Not with some of the […]

Two challenging issues in biological testing are devices’ portability and to using as little sample as possible. With this framework in mind, lab-on-a-chip devices play a major role, as they aim to integrate most of the facilities of a biology or chemistry laboratory in just a few millimeters device. They are basically made of micrometer […]
