New process could usher in "graphene-driven industrial revolution"

By - June 26, 2015 2 Pictures

It's hard to find an article about graphene that doesn't include the words "wonder material" somewhere within it. Less wondrous, unfortunately, is the expensive and time consuming chemical vapor deposition (CVD) process used to produce it industrially. Now researchers from the University of Exeter claim to have discovered a new low-cost technique to produce high quality graphene that could see the wonder material start to realize its potential.

Study finds early warning signals of global ocean conveyor belt collapse

By - December 9, 2014 1 Picture
We could see early warning signs of the collapse of a key component of the global climate up to 250 years in advance, a new study has shown – ample time to either prevent or prepare for the consequences of abrupt climate change. The University of Exeter study analyzed the Atlantic Meridional Overturning Circulation (AMOC), sometimes referred to as the global ocean conveyor belt, in a highly-complex and realistic simulation model, and identified the likely mechanisms that would drive such a collapse.

"Nano-pixels" hold huge potential for flexible, low-power, high-res screens

By - July 10, 2014 2 Pictures
The Retina displays featured on Apple's iPhone 4 and 5 models pack a pixel density of 326 ppi, with individual pixels measuring 78 micrometers. That might seem plenty good enough given the average human eye is unable to differentiate between the individual pixels, but scientists in the UK have now developed technology that could lead to extremely high-resolution displays that put such pixel densities to shame.

Fruit-inspired fibers change color when stretched

By - February 5, 2013 6 Pictures
Materials scientists at Harvard University and the University of Exeter have invented a new class of polymer fibers that change color when stretched. As is often seen in nature, the color is not the result of pigments, but rather comes from the interference of light within the multilayered fiber. Inspired by Margaritaria nobilis – also known as the Bastard Hogberry – the new fibers may lead to new forms of sensors, and possibly to smart fabrics whose color changes as the fabric is stretched, squeezed, or heated.

Medieval manuscripts go digital

By - November 11, 2012 3 Pictures
The 10th century is meeting the 21st with the University of Exeter announcing the development of an app that will make medieval manuscripts available to the public. The app, which is being developed in collaboration with interactive museum technology company Antenna International, will allow students and the general public to study manuscripts that until now have been too fragile to be even exhibited.

New "GraphExeter" material could enable “smart” mirrors, windows or t-shirts

By - April 29, 2012 1 Picture
Currently, virtually all touchscreen displays found in our electronic devices rely on a coating of indium tin oxide (ITO). It is used because of its electrical conductivity, its optical transparency, and the ease with which it can be deposited onto a display as a thin film. Using graphene, researchers at the University of Exeter have developed a viable alternative to increasingly expensive ITO that they claim is the “most transparent, lightweight and flexible material ever for conducting electricity.” Read More
