TiO2/CuS core-shell nanorod arrays with aging-induced photoelectric conversion enhancement effect

Dissecting the Chain Length Effect on Separation of Alkane-in-Water Emulsions with Superwetting Microchannels

“…The foams were decorated with TiO 2 nanotube arrays by electrochemical anodization in ethylene glycol (anhydrous, 99.8%, Sigma-Aldrich) containing 18.3 vol % deionized water and 0.3 wt % ammonium fluoride (NH 4 F, 98%, Sigma-Aldrich). The electrolyte pretreatment was performed as detailed in our previous reports. , Anodization was carried out at 40 V and room temperature (about 22 °C) for 3 h. The as-anodized foams were rinsed with ethanol and dried in air and then annealed at 450 °C for 3 h in a furnace (LE 14/11/B150, Nabertherm). To obtain superhydrophobic channels, the annealed foams were immersed in n -hexane (99%, Adamas) containing 0.5 vol % trichloro­(1 H ,1 H ,2 H ,2 H -perfluorooctyl)­silane (TPFS, 97%, Sigma-Aldrich) for 30 min and then annealed under a nitrogen atmosphere at 110 °C for 1 h.…”

A hybrid photodetector of graphene/TiO2/inorganic PbS quantum dots for fast response

“…After being tested in the ambient conditions, the surface of the SLG devices was covered by TiO 2 films (the thickness ∼20 nm) with a magnetron sputtering technique. The PbS QDs layer is produced at room temperature conditions using a simple spincoating method based on aqueous solution, [28][29][30][31] and the PbS QDs formed by this method are isolated and embedded by the ZnS matrix (the detailed steps for the deposition of PbS QDs are provided in supporting information). So the structure of the QDs layer maintains ultrahigh stability in the ambient conditions.…”
