Photodetectors made with graphene can process and conduct both light signals and electric signals extremely fast. Upon optical stimulation, graphene generates a photocurrent within picoseconds. Until now, none of the available methods were fast enough to measure these processes in graphene. Scientists have now developed a method to measure the temporal dynamics of this photo current.
Currently being developed by DARPA researchers at Washington-based Innovega iOptiks are contact lenses that enhance normal vision by allowing a wearer to view virtual and augmented reality images without the need for bulky apparatus.
Faculty of 1000 (F1000) today announces F1000 Research, a new fully Open Access publishing program across biology and medicine that will launch later this year. It is intended to address the major issues afflicting scientific publishing today: timely dissemination of research, peer review, and sharing of data.
Scientists have found a way to distort the atomic arrangement and change the magnetic properties of an important class of electronic materials with ultra-short pulses of terahertz (mid-infrared) laser light without heating the material up.
Researchers in France have recently encapsulated nanovesicles within slightly larger vesicles. This "Russian doll" structure mimics the organization of cell compartments. Reproducing it is a first major step towards triggering controlled reactions within the structure of the cell.
In order to find a method for more cost-effective data storage, a group of researchers from the DFG-Center for Functional Nanostructures at the Karlsruhe Institute of Technology in Germany and the National Tsing Hua University in Taiwan have created a DNA-based "write-once-read-many-times" (WORM) memory device.
Dr Clemens Franz leads a group of researchers at the DFG-Center for Functional Nanostructures at Karlsruhe Institute of Technology where he works on expanding the use of AFM for cell biological applications.
The heart's inner workings are mysterious, perhaps even more so with a new finding. Engineers at the University of Washington have discovered an electrical property in arteries not seen before in mammalian tissues.
