This paper describes high porosity titanium dioxide (TiO2) films deposited via atmospheric pressure chemical vapour deposition (APCVD) using tetraisopropyl titanate at deposition temperatures (Tdep) of 250C and 450C in excess water vapour. Films deposited at low Tdep exhibit a very low refractive index (nfilm) and high porosity (), up to 87% of the bulk rutile phase. High-temperature sinteri...
In this work, we developed a novel light-up nanocluster beacon (NCB) based on shuttling dark silver nanoclusters (NCs) to a bright scaffold through hybridization. The fluorescence enhancement was as high as 70-fold when the two templates were on the opposite sides of the duplexes, enabling sensitive and selective detection of DNA.
An active, recoverable, and recyclable nanocluster catalyst, Au25(SR)18(-), has been developed to catalyze the formation of α,β-unsaturated ketones or aldehydes from propargylic acetates. The catalytic process has been proposed to be initialized by an SN2' addition of OH(-). Moreover, a dramatic solvent effect was observed, for which a rational explanation was provided.
Two unprecedented tetrameric selenotungstates based on different Wells-Dawson-type fragments have been obtained: the {Sn7Se8W54} nanocluster exhibiting photocatalytic H2 evolution activity and the {Sn16Se11W56} chain, which are the first dimethyltin-functionalized selenotungstates reported and contain the unique {β-Se2W15} and {γ-Se2W14} building blocks, respectively.
