| Novel ultra-fast electrical circuits use light-generated tunneling currents Posted: 09 Apr 2014 06:36 AM PDT Scientists have successfully designed and fabricated electrical circuits that can operate at hundreds of terahertz frequencies, which is tens of thousands times faster than today's state-of-the-art microprocessors.  |
| Future computers that are normally off Posted: 08 Apr 2014 09:19 AM PDT Researchers have broadly envisioned the future of spin-transfer torque magnetoresistive random access memory (STT-MRAM), and they have now described how it will radically alter computer architectures and consumer electronics.  |
| 3-D printing trials of unmanned aircraft broaden possibilities for this emergent technology Posted: 08 Apr 2014 08:14 AM PDT Engineers have successfully printed a 1.5m-wide prototype unmanned aerial vehicle (UAV) for a research project looking at 3D printing of complex designs. The engineers said the polymer craft could form the basis of cheap and potentially disposable UAVs that could be built and deployed in remote situations potentially within as little as 24 hours.  |
| Graphene nanoribbons as electronic switches Posted: 08 Apr 2014 04:48 AM PDT A new theoretical study shows the conductivity conditions under which graphene nanoribbons can become switches in externally controlled electronic devices. One of graphene's most sought-after properties is its high conductivity. Physicists have now successfully calculated the conditions of the transport, or conductance mechanisms, in graphene nanoribbons.  |
| Researching materials to optimize lithium-ion battery performance Posted: 08 Apr 2014 04:48 AM PDT Creating environment friendly energy storage systems, non-explosive and with charge/discharge long-term cycles, motivated a group of scientists to research which polymeric materials have the properties to maintain the highest level of energy in a lithium - ion battery.  |
