Nano Based Photocatalytic Degradation of Pharmaceuticals

, 2017
The removal of emerging contaminants from wastewater is urgently required and even more necessary for wastewater reuse. Since conventional WWTPs are not designed to treat water polluted with pharmaceuticals present at trace levels, the applied treatments are mostly ineffective in their removal. Therefore the use of more efficient processes for removing

Elucidating the Role of Surface Ligands on the Oxidative Etching of Au Bipyramids During Photothermia Using Liquid Cell Transmission Electron Microscopy

Advanced Functional Materials, EarlyView.
Gold bipyramids can act as efficient plasmonic nanoheaters, but they often reshape during laser heating. This study shows that oxygen nanobubbles drive oxidative etching and that surface ligands control stability. CTAB‐ and citrate‐coated particles blunt and lose optical performance, whereas polystyrene sulfonate preserves shape and heating by ...
