As we reported in Macromolecules, 2010, 43, 5066–5074, vigorous magnetic stirring of this mixture over two days leads to a change in morphology to finite (1 to 2 mm) networks consisting of interconnected cylindrical PS struts surrounded by a P4VP corona in which the QDs are embedded..

Silver island films grown by thermal evaporation were coated with a thin layer (from 2.5 to 5 nm) of alumina by atomic layer deposition (ALD), which protects and stabilizes the SERS-active substrate without eliminating the Raman enhancement.. The temporal stability of the alumina-coated silver island films was examined by measurement of the Raman intensity of rhodamine 6G molecules deposited onto bare and alumina-coated silver substrates over the course of 34 days.

A strategy to accelerate the polymerization of phenolic resins by using strongly acidic conditions is proposed.. The self-assembly of resorcinol-formaldehyde and block copolymers (e.g., F127) under highly acidic concentrations (e.g., 1.5 M HCl) is probably driven by the I+X-S+ mechanism and hydrogen bonding and affords a highly reproducible approach for synthesis of ordered mesoporous carbons.

Despite having small particle sizes and high enough water partial pressure these Au/C3N4 catalysts are inactive for the gas phase and liquid phase oxidation of carbon monoxide.. The reason for the lack of activity is attributed to the lack of surface −OH groups on the C3N4. |
