News On Metasurface for photocatalyst enhancement

In this days, the Journal of Nano select publishes a new paper entitled as “Two-dimensional photonic metasurfaces for slow light-controlled photocatalysis” Photocatalysis using semiconductor materials like titania (TiO2) is a key method for environmental purification or solar fuel generation. Nanostructures that maximize incident light absorption are highly desired to enhance depollution rate or solar-to-fuel conversion […]

News On Quantum Plasmonics

In this days, the journal of Advanced Materials publishes a new paper entitled as “Quantum Plasmonics: Energy Transport Through Plasmonic Gap” At the interfaces of metal and dielectric materials, strong light–matter interactions excite surface plasmons; this allows electromagnetic field confinement and enhancement on the sub-wavelength scale. Such phenomena have attracted considerable interest in the field […]
