Silicone Nanofilament Support Layers in an Open-Channel System for the Fast Reduction of Para-Nitrophenol [PDF]

open access: yesNanomaterials, 2021
Chemical vapor phase deposition was used to create hydrophobic nanostructured surfaces on glass slides. Subsequently, hydrophilic channels were created by sputtering a metal catalyst on the channels while masking the outside. The surface tension gradient
