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 ...
Motion of a charged particle in magnetic field is described by the change in the direction of motion. It is described as magnetic field which is capable of only changing direction of motion. Motion of ...
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 ...
