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.

Food waste mixed with carbon nanotubes could store solar and wind energy

Some scientists have been exploring sugar alcohols as a possible material for making thermal storage work, but this direction has some limitations. One group of researchers wanted to investigate how mixing carbon nanotubes with sugar alcohols might affect their energy storage properties.

Where nanotechnology can learn from green chemistry

The intersection of nanotechnology and green chemistry presents an excellent opportunity to ensure that both fields can learn from each other.
