Shrinking sensor means faster, more accurate results

December 23, 2014
A novel sensor that has miniaturised optical emission spectrometers could make the analysis of gold and steel more precise and less time consuming. Researchers from the Fraunhofer Institute for Microelectronic...

Microbullet hits confirm graphene’s strength

December 2, 2014
Scientists at Rice University have developed a technique to fire microbullets at graphene sheets to show that multilayer graphene – 10 to 100 nm thick – may make excellent body...

New sensor for MRI and fluorescent imaging

November 26, 2014
Nanoparticles capable of simultaneously performing fluorescent and magnetic resonance imaging (MRI) in living animals have been developed by chemists at MIT. These particles could track specific molecules produced in the...

Lipid membrane ink gives nanometre resolution

October 16, 2014
Lipid membranes have been used as a biological ‘ink’ to draw in the nanometre region in a new technique developed by Leeds researchers. Resolution as low as six nanometres was...

Maglev to allow manufacture using soft materials

September 12, 2014
A system which allows objects to float in suspension could aid manufacturing with fragile materials say scientists – and it uses magnets similar to those found in the fridge. Harvard...

Biomimetic sheets offer improved chemical functionality

September 10, 2014
A two-dimensional biomimetic material with customisable properties able to self-assemble at an oil-water interface has been developed at the Lawrence Berkeley National Laboratory. The research could pave the way to...

Silicene promise for electronics

August 20, 2014
Thick multilayers of silicene can remain intact when exposed to air for at least 24 hours, making it a promising material for the electronic industry. Silicene is made from single,...

Perovskite – the new photovoltaic on the block

August 11, 2014
Move over graphene – there’s a new kid on the photovoltaics block – and it can be spray-painted. Spray-painting has been used to produce solar cells using organic semiconductors, but...

‘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...
