'Evolving electronics' could lead to new electrical devices

06-Sep-2016

Researchers have taken their inspiration from nature to teach materials to form new electrical pathways. They say the finding could eventually lead to new electronic devices. Scientists in Durham University’sSchool of Engineering & Computing Sciencestrained tiny carbon nanotubes, suspended in a ...

The unbearable lightness of helium may not be such a problem after all

21-Aug-2015

Helium gas may not be on the verge of running out after all. Previous studies had raised concerns that we were getting close to a world shortage of helium, but a new study shows that in many areas of North America, there is the potential for undiscovered quantities of helium to be associated with ...

Carbon nanotube computing?

Single-walled carbon nanotube composites show great promise for many things - including use as a material in 'unconventional' computing

09-Apr-2015

As we approach the miniaturization limits of conventional electronics, alternatives to silicon-based transistors--the building blocks of the multitude of electronic devices we've come to rely on--are being hotly pursued.Inspired by the way living organisms have evolved in nature to perform ...

Moving the MRI goalposts

28-Nov-2013

Scientists in the UK have developed a new class of MRI (magnetic resonance imaging) agents that promise to deliver clearer images more quickly. Chemical shifts from proton NMR normally fall between 0-12ppm, but water and fat resonate at 4.7 and 1.3ppm respectively, causing noise that can overlap ...

Solar activity playing a minimal role in global warming

11-Nov-2013

Changes in solar activity have contributed no more than 10 per cent to global warming in the twentieth century, a new study has found. The findings, made by Professor Terry Sloan at the University of Lancaster and Professor Sir Arnold Wolfendale at the University of Durham, find that neither ...

Public must be involved in nanotech policy debate demands groundbreaking

29-Sep-2009

Decision-making on science – especially emerging technologies such as nanotechnology – must become more democratic, a new report on science policy argues. The group of leading European academics behind the 'Reconfiguring Responsibility' report argue forcefully that current governance activities ...

From Enzymes to MOFs

17-Oct-2008

UK scientists have used dioxygenase enzymes to create enantiopure organic molecules, which in turn have been used to create chiral metal-organic frameworks. Dioxygenase enzymes were sourced from modified bacterial whole cells (mutants), isolated from the environment. These were then used as ...
