The photoreduction of monofluorinated phenols and benzoic acids on polyphosphate capped ZnS nanoparticles is examined. Defluorination is monitored using 19 F NMR. Photoreductive defluorination on ZnS nanoparticles produces fluoride while direct photo

Organo-silica sol–gel membranes have been prepared and demonstrated in a single layer format for pH measurement and multiple-layer format for both carbon dioxide and ammonia. The sensors are simple and versatile since the same chemistry and membran

This paper reports the detection of uranyl ion via fluorescence quenching of a dye molecule followed by the selective photocatalysis of the dye molecule by excited state uranyl. We have found that selectivity can be obtained when calcein, a highly fl

A capillary biosensor is demonstrated which uses the waveguiding properties of the capillary to integrate the signal over an increased surface area without simultaneously increasing the background noise from the detector. This biosensor achieves limi

The uniform deposition of a silane monolayer upon glass has been shown to require small amounts of water along with hydroxyl groups in an isolated or geminal configuration on the substrate surface. In order to expose these groups, organic compounds a
