photoinduced thiol ene Polymerization Reaction for fast preparation of macroporous hybrid monoliths and their application in capillary liquid chromatography
Chemical Communications, 2014Co-Authors: Junjie Ou, Hongwei Wang, Jing DongAbstract:Hybrid monoliths with a macroporous structure were prepared within a few minutes via a photoinduced thiol–ene Polymerization Reaction, the surfaces of which showed hydrophobic character. The monolithic column demonstrated good separation performance towards alkylbenzenes, peptides, proteins and BSA tryptic digest in cLC.

effects of solvent on the furfuryl alcohol Polymerization Reaction uv raman spectroscopy study
Catalysis Today, 2013Co-Authors: Rajeev S Assary, Christopher L Marshall, David J Gosztola, Larry A Curtiss, Peter C StairAbstract:Abstract The effect of alcohol as a solvent on the acid-catalyzed conversion of furfuryl alcohol ( FA ) into polymerized furfuryl alcohol ( PFA ) has been studied by UV Raman spectroscopy. The major peak intensity ratios were compared to gain quantitative information about the extent of Polymerization in various solvents. The Reaction rate of the Polymerization has been found to significantly decrease with increasing concentrations of ethanol or butanol ( n -butanol and iso -butanol). Compared to ethanol, longer or branched chain alcohols such as n -butanol and iso -butanol can marginally reduce the acid-catalyzed Polymerization at room temperature. The plot of reciprocal intensity of the characteristic Raman band of FA vs. the Reaction time suggests that the Polymerization Reactions follow second-order kinetics.

the use of instantaneous distributions in Polymerization Reaction engineering
Macromolecular Reaction Engineering, 2014Co-Authors: Joao B P SoaresAbstract:This article shows how the method of instantaneous distributions can be used to model the microstructures of polymers made under different Polymerization conditions. The three main distributions investigated are the distributions of chain length (CLD), chemical or comonomer composition (CCD), and long chain branching (LCBD). It is also explained how the method of instantaneous distributions can be combined with reactor models to calculate the cumulative distribution of polymers made in reactors having different residence time distributions, spatial and time gradients. Finally, the usefulness of this mathematical modeling technique is illustrated in several case studies involving olefin Polymerization. Extensions for free-radical Polymerization are covered in the appendices.

Polymerization Reaction engineering metallocene catalysts
Progress in Polymer Science, 1996Co-Authors: A E Hamielec, Joao B P SoaresAbstract:Abstract Metallocene catalysts are operative in all existing industrial plants that are presently used for polyolefin manufacture and have the potential to revolutionize the technology for the production of these polymers. A review of metallocene catalysis and its effects on polymer process engineering for the manufacture of polyolefins is provided. This review concentrates on the aspects of polymer reactor engineering, mathematical modelling of Polymerization processes, and the characterization of polyolefins made with these novel catalysts.

sensitive fluorescence detection of nucleic acids based on isothermal circular strand displacement Polymerization Reaction
Nucleic Acids Research, 2009Co-Authors: Xiaohai Yang, Kemin Wang, Wei Li, Hongxing Tang, Huimin LiAbstract:Here we have developed a sensitive DNA amplified detection method based on isothermal stranddisplacement Polymerization Reaction. This method takes advantage of both the hybridization property of DNA and the strand-displacement property of polymerase. Importantly, we demonstrate that our method produces a circular Polymerization Reaction activated by the target, which essentially allows it to self-detect. Functionally, this DNA system consists of a hairpin fluorescence probe, a short primer and polymerase. Upon recognition and hybridization with the target ssDNA, the stem of the hairpin probe is opened, after which the opened probe anneals with the primer and triggers the Polymerization Reaction. During this process of the Polymerization Reaction, a complementary DNA is synthesized and the hybridized target is displaced. Finally, the displaced target recognizes and hybridizes with another probe, triggering the next round of Polymerization Reaction, reaching a target detection limit of 6.4 � 10 –15 M.
