Funded by the Air Force, Brian Gilchrist and his colleagues are developing a new type of thruster that uses nanoparticles as propellant. Much of the engine is etched directly onto a wafer-thin piece ...
Mapping the electrostatic force field of single molecules from high-resolution scanning probe images
How electronic charge is distributed over a molecule determines to a large extent its chemical properties. Here, we demonstrate how the electrostatic force field, originating from the inhomogeneous ...
