(Phys.org) —Recent evidence suggests that the Roman craftsmen who created the Lycurgus Cup, a glass drinking goblet, used nanotechnology to cause the goblet to change color under different lighting. The cup's unique properties ...
Two NJIT researchers have demonstrated that using a continuum-based approach, they can explain the dynamics of liquid metal particles on a substrate of a nanoscale. "Numerical simulation of ejected molten metal nanoparticles ...
