Intrinsic short hole diffusion length is a well-known problem for α-Fe2O3 as a visible-light photocatalytic material. In this paper, a nanodisk morphology was designed to remarkably enhance separation of electron-hole pairs of α-Fe2O3. As expected, α-Fe2O3 nanodisks presented superior photocatalytic activity toward methylene blue degradation: more than 90% of the dye could be photodegraded with...

Manipulation of light-matter interaction is critical in modern physics, especially the strong coupling regime. Based on highly localized field enhancement near field, we demonstrate that can be achieved dielectric-metallic hybrid structure consisting a perforated Si nanoblock filled with slotted Ag nanodisk (nanoprism) its center. Large Rabi splitting 275 (262) meV due to generation new energy ...

Scanning electrochemical microscopy (SECM) has been extensively applied in biological analysis such as measuring catalytic activity, monitoring the metabolism, investigating the neurotransmitter secretion, and imaging the morphology due to its ability in quantitative measurements of both intercellular and intracellular physiological processes. Unlike scanning ion conductance microscopy, these m...
