Novel light sources made of two-dimensional materials

Physicists have designed a light source that emits photon pairs. Two-photon sources are particularly well suited for tap-proof data encryption. The experiment's key ingredients: a semiconductor crystal and some sticky tape.

Nanotechnology engineers design an infinitesimal computing device

Engineers have developed a design for a functional nanoscale computing device. The concept involves a dense, three-dimensional circuit operating on an unconventional type of logic that could, theoretically, be packed into a block no bigger than 50 nanometers on any side.

Introducing metallic ions within a DNA molecule will have many uses in bio- and nanotechnology

Scientists have proven, for the first time, that introducing slight chemical modifications in DNA molecules may allow to introduce metallic ions in it, keeping its double-stranded structure and molecular recognition properties (for other DNA molecules, enzymes, proteins, etc.).

Prototype device for measuring graphene-based electromagnetic radiation created

Physicists have studied carbon structures, obtained from the reduced graphene oxide. They the created a bolometer prototype on the basis of these structures.

Metamaterial device allows chameleon-like behavior in the infrared

An electric current will not only heat a hybrid metamaterial, but will also trigger it to change state and fade into the background like a chameleon in what may be the proof-of-concept of the first controllable metamaterial device, or metadevice, according to a team of engineers.

Controlling the properties of matter in two-dimensional crystals

By creating atomic chains in a two-dimensional crystal, researchers believe they have found a way to control the direction of materials properties in two and three dimensional crystals with implications in sensing, optoelectronics and next-generation electronics applications.

'Nanobottles' offer blueprint for enhanced biological imaging

Researchers have developed a new technique to provide cellular 'blueprints' that could help scientists interpret the results of X-ray fluorescence (XRF) mapping.
