(PhysOrg.com) -- When Enrico Fermi investigated the Rydberg atom in the '30s, he never imagined that the giant atoms could form molecules. Later, in the '70s and '80s, theoretical physicist Chris Greene predicted that Rydberg ...
A polymer is a mesh of chains, which slowly break over time due to the pressure from ordinary wear and tear. When a polymer is squeezed, the pressure breaks chemical bonds and produces free radicals: ions with unpaired electrons, ...
