Modeling of a Chemical Looping Combustion Process in Interconnected Fluidized Beds with a Cu‐Based Oxygen Carrier
Authors: Wang S. , Lu H. L. , Tang Y. , Li D. 
Published: August 2013

AbstractChemical looping combustion (CLC) is a promising technology for CO2 capture, with inherent CO2 separation and low energy consumption. In this study, the reactive multiphase model is incorporated into a computational fluid dynamics code to simulate the reactive fluid dynamics in the CLC reactor with a two‐fluid model. The solid friction stress is used to account for the interaction of individual particles with their neighbors through sustained contact at high particle concentrations and the kinetic theory of granular flow is used for closure. Gas‐solid flow characteristics and chemical reactions in interconnected fluidized beds using a Cu‐based oxygen carrier are simulated. The distributions of solid concentration and gas composition are obtained. The predicted gas compositions at the outlet agree with experimental results. The effects of the operating velocity and the temperature on the combustion efficiencies are also shown. The results demonstrate that a higher bed temperature at a lower operating velocity could enhance the CLC performance.

Published: August 2013

AbstractRecent investigations have rekindled interest in 8‐hydroxyquinolines as therapeutic agents for cancer, Alzheimer’s disease, and other neurodegenerative disorders. Three new β‐cyclodextrin conjugates of 8‐hydroxyquinolines and their copper(II) and zinc(II) complexes have been synthesized and characterized spectroscopically. In addition to improving aqueous solubility, due to the presence of the cyclodextrin moiety, the hybrid systems have interesting characteristics including antioxidant activity, and their copper(II) complexes are efficient superoxide dismutase (SOD) mimics. The ligands and their copper(II) complexes show low cytotoxicity, attributed to the presence of the cyclodextrin moiety. These compounds have potential as therapeutic agents in diseases related both to metal dyshomeostasis and oxidative stress.
Synthesis of PAF, an Antifungal Protein from P. chrysogenum, by Native Chemical Ligation: Native Disulfide Pattern and Fold Obtained upon Oxidative Refolding

Published: August 2013

AbstractThe folding of disulfide proteins is of considerable interest because knowledge of this may influence our present understanding of protein folding. However, sometimes even the disulfide pattern cannot be unequivocally determined by the available experimental techniques. For example, the structures of a few small antifungal proteins (PAF, AFP) have been disclosed recently using NMR spectroscopy but with some ambiguity in the actual disulfide pattern. For this reason, we carried out the chemical synthesis of PAF. Probing different approaches, the oxidative folding of the synthetic linear PAF yielded a folded protein that has identical structure and antifungal activity as the native PAF. In contrast, unfolded linear PAF was inactive, a result that may have implications concerning its redox state in the mode of action.
Dynamic Kinetic Resolution of Homoallylic Alcohols: Application to the Synthesis of Enantiomerically Pure 5,6‐Dihydropyran‐2‐ones and δ‐Lactones
Authors: Warner Madeleine C. , Shevchenko Grigory A. , Jouda Suzan , Bogár Krisztián , Bäckvall Jan‐E. 
Published: August 2013

AbstractDynamic kinetic resolution of various homoallylic alcohols with the use of Candida antarctica lipase B and ruthenium catalyst 2 afforded homoallylic acetates in high yields and with high enantioselectivity. These enantiopure acetates were further transformed into homoallylic acrylates after hydrolysis of the ester function and subsequent DMAP‐catalyzed esterification with acryloyl chloride. After ring‐closing metathesis 5,6‐dihydropyran‐2‐ones were obtained in good yields. Selective hydrogenation of the carboncarbon double bond afforded the corresponding δ‐lactones without loss of chiral information.
