Energy against the current on a quantum scale, without contradicting the laws of physics

ScienceDaily.com: Nanotechnology News - Fri, 10/06/2017 - 19:23
In a classical thermodynamic system, the heat current flows from the hotter body to the colder one, or electricity from the higher voltage to the lower one. The same thing happens in quantum systems, but this state can be changed, and the flow of energy and particles can be reversed if a quantum observer is inserted into the system.

Graphene origami - folding with 'colors'

NanoWerk.com - Fri, 10/06/2017 - 18:21
Just like traditional paper origami that results in complicated 3D structures from 2D paper, graphene origami allows the design and fabrication of carbon nanostructures that are not naturally existing but of desirable properties. In a new report, researchers describe how p-type and n-type doping of 2D sheets like graphene in selected areas could be exploited as two 'colors' to guide the sheets into preferred folded shapes where complementarily doped areas maximize their mutual overlap.
