Advances in nanofabrication have shifted surface tension engineering from the realms of chemistry to nanomechanics. As CJ Kim told attendees at the Nano Korea 2016 plenaries, nanomechanical surface tension design has a huge role to play in a range of technologies from ink-jet printing and superhydrophobic surfaces, to drag reduction in boat design…… http://nanotechweb.org/cws/article/tech/65793
Researchers at the Institute of Robotics and Intelligent Systems at ETH Zurich in Switzerland have made a new type of nanoswimmer with a flexible tail that is propelled by acoustic waves. The nanobot might be used in a host of application areas, including drug delivery, non-invasive surgery, material assembly, lithography and even water treatment……… http://nanotechweb.org/cws/article/tech/65829 […]
Researchers in China and the US have made a new safety helmet that is powered by a triboelectric nanogenerator and an electromagnetic generator.
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 […]
An abrupt change in the electrical conductivity at the transition point between two so-called charge-density-wave phases in 2D tantalum disulphide-boron nitride-graphene channels can be exploited
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 […]
Artificial neural networks have been used to simulate interactions between water molecules and provide important clues about the remarkable properties of this live-giving substance. The study has been carried out by physicists in Germany and Austria, who used the networks to perform simulations 100,000 times faster than possible with conventional computers. Their work offers explanations […]
Researchers in the US have succeeded in chemically assembling the electronic junctions between a 2D semiconductor (molybdenum sulphide) and graphene, and have made an atomic transistor with good properties. They have also assembled the heterostructures into 2D logic circuits, such as an NMOS inverter with a voltage gain as high as 70…………. http://nanotechweb.org/cws/article/tech/65627 The graphene–MoS2 […]
A 3D artificial scaffold network made from multi-walled carbon nanotubes (MWCNTs) could help locally “rewire” nerve tissue. This is the new finding from researchers in Italy and Spain, who say that the technology could be exploited as a neural interface to help repair nerve fibres after injury or disease……. http://nanotechweb.org/cws/article/tech/65631 3D carbon nanotube framework scaffolds […]
