Mechanical pixels for energy efficient colour displays

Researchers from TU Delft and Graphenea in Spain have found a way to create what they call 'mechanical pixels'. While the pixels, created using balloon like structures, do not emit light, they could be used in energy-efficient colour displays for a range of applications.

The 'pixels' are 13µm wide circular indents in silicon covered by a double layer of graphene, which encloses air inside the cavities. When the researchers observed the pixels, they saw their ...

Predicting noise in photonic circuits

Researchers at the Moscow Institute of Physics and Technology believe it will be possible to predict accurately the level of noise caused by the amplification of photonic and plasmonic signals in nanoscale optoelectronic circuits. The scientists say their approach could be used not only to evaluate the ultimate data transfer rates in emerging optoelectronic devices, but also to discover the fundamental bandwidth limitations of nanophotonic interfaces.

Improving electrical contact in nanowires

A research team from Swansea University has found ways of improving electrical contact technology on minute scales with simple modifications to nanowires. The technology could be used to develop enhanced devices based on the nanomaterials.

Graphene can superconduct, says research team

Researchers at Cambridge University say they have found a way for graphene to act as a superconductor. Until now, superconductivity in graphene has only been achieved by either doping it with, or placing it on, a superconducting material, which can compromise some of its other properties.

Positive ions boost speed of lithium in batteries

Faster recharging lithium batteries could be developed according to research groups from the University of Bath and the University of Illinois at Chicago, who have discovered that adding charged metal atoms to tunnel structures within batteries improves their performance.

Proteins provide low cost colour for LCDs

A hybrid material made with a 3D printing technique has been used to design a low cost and ecological screen by scientists at the University of Erlangen-Nurnberg in Germany. The material's luminescent proteins can be used in backlighting systems and colour filters.

2D materials break differently

The 2D material molybdenum disulphide (MoS2) has been seen to crack at the atomic level for the first time by scientists at the Institute for Basic Science in Korea. The study is expected to contribute to improving applications of new 2D materials, in future electronic and photoelectric devices.

Self-assembly of nanostructures to form toroids

Researchers from KAUST and the Max-Planck-Institute of Colloids and Interfaces are trying a bottom-up philosophy to harness the natural forces between nano- and microstructures. They claim engineered microstructures have an array of uses in electronics, sensors and biomedical applications.

Microbial nanowires for green electronics

A new type of natural wire produced by bacteria has been discovered by microbiologists at the University of Massachusetts Amherst. The discovery could accelerate the development of sustainable conducting materials for the electronics industry.
