Experimental Study on OH*, CH*, and CO* Chemiluminescence Diagnosis of CH/O Diffusion Flame with CO-Diluted Fuel.

OH* and CH* chemiluminescence in hydrocarbon flames are often applied to characterize flame structure, equivalence ratio, strain rate, heat release rate, etc. In this study, chemiluminescence images of OH*, CH*, and CO* in the CH/O diffusion flame were obtained using a CCD camera imaging system. The effect of CO dilution on the flame structure, strain rate, and other flame characteristics of CH/O diffusion flame was discussed.

Sunlight and UV driven synthesis of Ag nanoparticles for fluorometric and colorimetric dual-mode sensing of ClO.

A photo-responsive compound BINOL-LA (1) having a rigid backbone ending up with two 5-membered cyclic disulfide moieties was designed. BINOL-LA capped Ag nanoparticles (1@Ag NPs) with a network structure were synthesized in a green way by sunlight or UV lamp irradiation. 1@Ag NPs exhibit a selective recognition towards ClO in aqueous solution with a switch-on fluorescence response and a visual color change, with detection limits of 0.
