Starting with simple carbon nanotubes, a team of researchers from the United Kingdom and Spain has developed a sugar-coated nanocapsule that can deliver large doses of radioactivity to tumors. The researchers envision developing a series of nanoscale delivery devices that can target specific organs in the body for radiation therapy or imaging by tinkering with the sugar coating on the nanocapsule.

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.

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.

(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 ...

(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 ...

(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 ...

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.

(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. ...
