Scientists report observing Rydberg moire excitons, which are moire-trapped Rydberg excitons in the monolayer semiconductor WSe2 adjacent to small-angle twisted bilayer graphene.
Researchers have developed a cellulose-based material, a mixture of hydroxpropyl cellulose with water, carbon nanotubes and cellulose nanofibrils, that changes color when heated or stretched - without the addition of any pigments.
