A soft cantilever beam, which can detect a very weak force, has been used by IRG1 researchers to uncover a striking property of cuprate superconductors: that trace supercurrents surrounding magnetic flux vortices persist for tens of degrees above the superconducting transition temperature Tc.
Princeton scientists have developed a new method for making gratings by prying apart two rigid plates that sandwich a thin, glassy polymeric film. The process fractures the film into complementary sets of ridges on each plate, with highly uniform ridge spacings ranging from 200 nm to 200 Â’µm, scaling directly with the film thickness.
A team of Princeton researchers has developed an enabling technique for manufacturing electro-optical devices from organic semiconductors.
A collaboration of experimentalists and theorists at the Chicago MRSEC has discovered a new, general route for creating nanoparticle monolayers that retain order across millions of particles, without holes, while staying compact over macroscopic distances.
