Human teams aided by a software system can make decisions more accurately and quickly in time-stressed situations than teams of just people, according to the Penn State researchers who developed the new software.
Physicists at the University of Pennsylvania have overcome a major hurdle in the race to create nanotube-based electronics. In an article in the August issue of the journal Nature Materials, available online now, the researchers describe their method of using nanotubes tiny tubes entirely composed of carbon atoms -- to create a functional electronic circuit. Their method creates circuits by dipping semiconductor chips into liquid suspensions of carbon nanotubes, rather than growing the nanotubes directly on the circuit.
