(Phys.org) —A trio of researches with Université Paris Diderot has found that viscoelastic fluids spontaneously form wings which in turn cause the formation of geometric shapes when the fluid is shot out of a jet at high ...
(Phys.org) —Surface catalysts are notoriously difficult to study mechanistically, but scientists at the University of South Carolina and Rice University have shown how to get real-time reaction information from Ag nanocatalysts ...
