Imperfections in the regular atomic arrangements in crystals determine many of the properties of a material, and their diffusion is behind many microstructural changes in solids. However, imaging ...

Scientists have created a new structure by encapsulating a single layer of fullerene molecules between two graphene sheets. Buckyball sandwiches combine fullerenes and graphene. This structure allows ...

In CdS nanocrystals, photoexcited holes rapidly become trapped at the particle surface. The dynamics of these trapped holes have profound consequences for the photophysics and photochemistry of these ...
