NIST researchers boost intensity of nanowire LEDs

Nanowire gurus at the National Institute of Standards and Technology (NIST) have made ultraviolet light-emitting diodes (LEDs) that, thanks to a special type of shell, produce five times higher light intensity than do comparable ...

1 + 1 does not equal 2 for graphene-like 2-D materials

Physicists from the University of Sheffield have discovered that when two atomically thin graphene-like materials are placed on top of each other their properties change, and a material with novel hybrid properties emerges, ...

Nano-bio-computing lipid nanotablet

Nanoparticles can be used as substrates for computation, with algorithmic and autonomous control of their unique properties. However, scalable architecture to form nanoparticle-based computing systems is lacking at present. ...

Technique streamlines fabrication of 2-D circuits

Exotic 2-D materials hold great promise for creating atom-thin circuits that could power flexible electronics, optoelectronics, and other next-generation devices. But fabricating complex 2-D circuits requires multiple time-consuming, ...

Chemists 'print' sensors for nano-objects

Young scientists from ITMO University proposed a new type of optical nano-sensors. Their operating principle is based on the interaction of light in thin films: a similar effect can be observed in soap bubbles. Such sensors ...

What happened to the hyped nanomaterials?

Carbon-based nano materials such as graphene and carbon nanotubes were predicted to have a brilliant future when they were discovered. But quality problems curb the development of new products. The problem is that it is difficult ...

New method of synthesising nanographene on metal oxide surfaces

Nanostructures based on carbon are promising materials for nanoelectronics. However, to be suitable, they would often need to be formed on non-metallic surfaces, which has been a challenge—up to now. Researchers at Friedrich-Alexander-Universität ...

Hall effect becomes viscous in graphene

Researchers at The University of Manchester in the UK have discovered that the Hall effect—a phenomenon well known for more than a century—is no longer as universal as it was thought to be.

Directed evolution builds nanoparticles

The 2018 Nobel Prize in Chemistry went to three scientists who developed the method that forever changed protein engineering: directed evolution. Mimicking natural evolution, directed evolution guides the synthesis of proteins ...

Now you see heat, now you don't

Hiding an object from heat-sensing cameras could be useful for military and technology applications as well as for research. Efforts to develop such a method have been underway for decades with varying degrees of success. ...
