A tiny laser that emits “twisted light” has been unveiled by researchers in the US and Italy. Measuring just 9 μm across, the semiconductor device can produce a beam of light that carries orbital angular momentum. While improvements are needed before the laser can be commercialized, it could someday be used to boost the bandwidth of […]

A team of researchers in the UK and Switzerland has unveiled a new theoretical framework to quantify how transparent a 2D material is to an electrostatic field. The theory will help physicists and device engineers design better quantum capacitors (an array of subatomic power storage components that can store high-energy densities, for example, in batteries) […]

Tungsten diselenide nanoflakes can be used to chemically convert carbon dioxide to carbon monoxide in an ionic liquid. This is the new finding from researchers at the University of Illinois at Chicago whose “photosynthetic” device works using only sunlight. The new type of solar cell could be used to remove carbon from the atmosphere and […]

Devices that combine inorganic and biological components are sought for a number of applications including healthcare monitoring, high-efficiency solar cells and beyond-silicon bioprocessors. In his presentation at Nano Korea 2016 earlier this month, Jeong Woo Choi reported some of the progress in this field, from cell-based nanobioelectronic devices to an artificial “raybot”……. http://nanotechweb.org/cws/article/tech/65750 Bioinspired concept […]

Researchers at EPFL in Switzerland and the University of Illinois at Urbana-Champaign in the US have used single-layer molybdenum disulphide (MoS2) nanopores as osmotic nanopower generators. The devices, which produce a large, osmotically induced current with a power density of up to 106 watts per square metre, can be used to power a MoS2transistor, thus […]
