Researchers move graphene electronics into 3D

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. Their research shows a transistor that may prove the missing link for graphene to become the next silicon.

Electronic salmon sandwich is paving the way towards cost-effective DNA memory device

In order to find a method for more cost-effective data storage, a group of researchers from the DFG-Center for Functional Nanostructures (CFN) at the Karlsruhe Institute of Technology (KIT) in Germany and the National Tsing Hua University in Taiwan have created a DNA-based “write-once-read-many-times” (WORM) memory device.

Researchers find molybdenite may be better suited for integrated logic circuits than graphene

(PhysOrg.com) -- Because of its physical limitations, silicon use in tiny integrated logic circuits will have to one day soon be replaced by something that can work in a smaller state. That is, if we want to see miniaturization of computer components to continue. For several years, graphene has been ...

Self-assembling nanorods: Researchers obtain 1-, 2- and 3-D nanorod arrays and networks

(PhysOrg.com) -- A relatively fast, easy and inexpensive technique for inducing nanorods - rod-shaped semiconductor nanocrystals - to self-assemble into one-, two- and even three-dimensional macroscopic structures has been developed by a team of researchers with the Lawrence Berkeley National Laboratory (Berkeley Lab). This technique should enable more effective use ...

Physics team calculates that graphene disks could be complete optical absorbers

(PhysOrg.com) -- In optical devices designed and used to collect light, there has always been a loss of light due to reflection, now, new research by a team of physicists from Spain and England has found, via calculation, that if charged graphene disks of just the right size were made ...

Nanoparticles used to increase thermal properties of transformer oil

Rice University scientists have created a nano-infused oil that could greatly enhance the ability of devices as large as electrical transformers and as small as microelectronic components to shed excess heat.

Engineers build first sub-10-nm carbon nanotube transistor

(PhysOrg.com) -- Engineers have built the first carbon nanotube (CNT) transistor with a channel length below 10 nm, a size that is considered a requirement for computing technology in the next decade. Not only can the tiny transistor sufficiently control current, it does so significantly better than predicted by theory. ...
