demineralization of organic pollutants on the dye modified tio2 semiconductor Particulate System using visible light
Applied Catalysis B-environmental, 2001Co-Authors: Debabrata Chatterjee, Anima MahataAbstract:Abstract Photodegradation of organic pollutants, viz. phenol, chlorophenol, 1,2-dichloroethane and trichloroethylene in water has been achieved on the surface of TiO2 semiconductor modified with thionine and eosin Y by using visible light. After 5 h of irradiation with a 50 W tungsten lamp, over 55–72% degradation of pollutants is achieved. A working mechanism involving excitation of surface bound dye, followed by charge injection into the TiO2 conduction band is proposed.

Catalysis Communications, 2001Co-Authors: Debabrata Chatterjee, Anima MahataAbstract:Photoassisted decomposition of phenol, chlorophenol and trichloroethylene in waste water has been achieved on the surface of TiO2 semiconductor modified with 8-hydroxyquinoline (HOQ) by using visible light. After 5 h of irradiation with a 50 W tungsten lamp, over 70–80% degradation of pollutants is achieved. A working mechanism involving excitation of surface bound dye, followed by charge injection into the TiO2 conduction band is proposed.

Reachability of particle size distribution in emulsion batch polymerization under mid-course correction policies
Proceedings of the 2003 American Control Conference 2003., 2003Co-Authors: Yang Wang, C.d. Immanuel, Francis J. DoyleAbstract:Rigorous reachability analysis is largely an open problem for nonlinear distributed Systems. A programming-based reachability analysis is proposed to address nominal and perturbed Systems, with the final distributed variables characterized as multi-Gaussian distributions. An application study is detailed for the feedback control of particle size distribution in emulsion polymerization, where the Particulate System is described by population balance models. The approach has been applied to a semibatch styrene emulsion polymerization process. The re-mapping of the reachable region in the case of mid-course correction shows the best performance achievable through in-batch control action.

Reachability analysis of particle size distribution in semibatch emulsion polymerization
2003 European Control Conference (ECC), 2003Co-Authors: Yang Wang, Francis J. DoyleAbstract:Emulsion polymerization is an economically important method of producing a number of polymer products, where particle size distribution (PSD) is an essential property of the latex produced. A programming-based approach has been proposed for reachability analysis of PSD for a general Particulate System described by population balance models, along with application to a semibatch styrene homopolymerization System. The reachable region is defined for both the nominal and perturbed cases, with final PSDs characterized as multi-Gaussian distributions. The evolution of the reachable region in the case of mid-course correction shows the best in-batch control performance achievable given limited PSD measurements.

photodegradation of phenol in a polymer modified tio2 semiconductor Particulate System under the irradiation of visible light
Catalysis Communications, 2007Co-Authors: Lin Song, Yueqi Mo, Dongdong Zhang, Ya XiongAbstract:Abstract Preparation methods and photocatalytic activity of the photocatalyst nanometer TiO 2 /poly-(fluorene-co-thiophene) (PFT) were studied under GaI 3 lamp irradiation in the present research. The degradation rate of phenol using the target photocatalyst was much higher than it was using TiO 2 /rhodamine B. Diffuse reflectance spectra showed that the absorbance range of TiO 2 /PFT was expanded from 387 nm (TiO 2 ) to about 500 nm, and fluorescent emission spectra showed that the spectral shape of TiO 2 /PFT was identical with that of pure PFT. The fluorescent quantum efficiency of TiO 2 /PFT was estimated at 3.8% while that of PFT film was about 14.7%, which indicated that electrons transferred from the PFT into the conduction band of TiO 2 .
