New wave of technologies possible after ground-breaking analysis tool developed
A revolutionary tool created by scientists at the University of Sheffield has enabled researchers to analyse nanometer-sized devices without destroying them for the first time, opening the door to a new wave of technologies. The nuclear magnetic resonance apparatus - developed by the University's Department of Physics and Astronomy - will allow for further developments and new applications for nanotechnology which is increasingly used in harvesting solar energy, computing, communication developments and also in the medical field.

No evidence for
No evidence for "knots" in space
Theories of the primordial Universe predict the existence of knots in the fabric of space - known as cosmic textures - which could be identified by looking at light from the cosmic microwave background (CMB), the relic radiation left over from the Big Bang. Using data from NASA's Wilkinson Microwave Anisotropy Probe (WMAP) satellite, researchers from UCL, Imperial College London and the Perimeter Institute have performed the first search for textures on the full sky, finding no evidence for such knots in space.

New silicon memory chip developed
New silicon memory chip developed
The first purely silicon oxide-based 'Resistive RAM' memory chip that can operate in ambient conditions - opening up the possibility of new super-fast memory - has been developed by researchers at UCL. Resistive RAM (or 'ReRAM') memory chips are based on materials, most often oxides of metals, whose electrical resistance changes when a voltage is applied - and they "remember" this change even when the power is turned off.

Honeycombs of magnets could lead to new type of computer processing
By Simon Levey Friday 30 March 2012 Scientists have taken an important step forward in developing a new material using nano-sized magnets that could ultimately lead to new types of electronic devices, with greater processing capacity than is currently feasible. Many modern data storage devices, like hard disk drives, rely on the ability to manipulate the properties of tiny individual magnetic sections, but their overall design is limited by the way these magnetic 'domains' interact when they are close together.

Scientists revolutionise electron microscope
Scientists revolutionise electron microscope
Scientists revolutionise electron microscope Researchers at the University of Sheffield have revolutionised the electron microscope by developing a new method which could create the highest resolution images ever seen. For over 70 years, transmission electron microscopy (TEM), which `looks through´ an object to see atomic features within it, has been constrained by the relatively poor lenses which are used to form the image.

Graphene electronics moves into a third dimension
Graphene electronics moves into a third dimension
Wonder material graphene has been touted as the next silicon, with one major problem – it is too conductive to be used in computer chips. Now scientists from The University of Manchester have given its prospects a new lifeline. In a paper published this week in Science , a Manchester team lead by Nobel laureates Professor Andre Geim and Professor Konstantin Novoselov has literally opened a third dimension in graphene research.
