(Phys.org)—As physicists work on miniaturizing devices, they will eventually run into the ultimate limit: the atom. A fundamental question in this area is whether it's even possible to scale down a macroscale engine such ...
It has been believed that Hall thrusters, an efficient kind of electric propulsion widely used in orbit, must be large to produce a lot of thrust. Now, a new study from the University of Michigan suggests that smaller Hall ...
