‘On-off switch’ controls crystal structure of graphene

May 16, 2014
American researchers have found an ‘on-off switch’ for graphene which enables them to change its crystal structure in a controlled fashion. Most materials require high temperature or pressure to change...

Rubber research leads to rarely seen hemihelix

May 1, 2014
A serendipitous discovery by scientists experimenting with elastic strips has resulted in a shape rarely seen in nature – a hemihelix. The Harvard team was trying to make two-dimensional springs...

Laser shows promise for solar cell efficiency

April 30, 2014
Solar cells based on perovskite not only excel at absorbing light but at emitting it too, turning them into low-cost lasers says an Oxbridge team. Their discovery raises expectations for...

Google Glass could aid Parkinson’s patients

April 24, 2014
Next generation wearable technology like Google Glass could be used as an assistive aid for those with the neurological condition Parkinson’s disease say researchers from Newcastle University’s Digital Interaction Group....

Antimony batteries a possibility

April 14, 2014
Scientists probing new materials for batteries have succeeded in producing uniform antimony nanocrystals which could one day be used as alternative anode materials in high-energy-density batteries.These nanocrystals are able to...

Hairy materials grown on microscale

February 27, 2014
Materials constructed of tiny little hairs self-assembled at the microscale could be used in the next generation of batteries and solar cells.The key ingredient is epoxy and when added to...

Gummy material could improve battery safety

February 12, 2014
A chewing gum-like material could dramatically improve the safety of lithium ion batteries by replacing the liquid acid electrolyte. High performance lithium batteries are great for storing large amounts of...

3D printing boost from cheap titanium powder

January 22, 2014
The high cost of titanium powder has prohibited its use in 3D printing – with plastics being the preferred alternative – but Rotherham-based Metalysis have developed a new way to...

A tip top approach to analysis

December 20, 2013
Nanotechnology can only develop with appropriate analysis and measurement. The ‘Lab on a chip’ capabilities of AFM is one way of achieving this – here we get a rundown of...

Graphene nanoribbons – an exercise in control

December 18, 2013
Graphene nanoribbons offer a range of useful properties. Now, with clever use of water and incredibly precise slicing, a research team from Rice University thinks they have mastered their difficult...
