A Functional Model of [Fe]-Hydrogenase

Rosario Scopelliti, Xile Hu, Matthew Wodrich, Tao Xu, Simona Mazza

[Fe]-Hydrogenase catalyzes the hydrogenation of a biological substrate via the heterolytic splitting of molecular hydrogen. While many synthetic models of [Fe]-hydrogenase have been prepared, none yet are capable of activating H-2 on their own. Here, we re ...

A Novel Nickel Pincer Complex in the Active Site of Lactate Racemase

Xile Hu, Tao Xu, Gerald Bauer

A recent study revealed the structure of the Ni-containing active site of lactate racemase. The Ni is coordinated by a SCS pincer ligand derived from a nicotinic acid mononucleotide. ...

Identification of HcgC as a SAM-Dependent Pyridinol Methyltransferase in [Fe]-Hydrogenase Cofactor Biosynthesis

Xile Hu, Tao Xu, Lichen Bai

Previous retrosynthetic and isotope-labeling studies have indicated that biosynthesis of the iron guanylylpyridinol (FeGP) cofactor of [Fe]-hydrogenase requires a methyltransferase. This hypothetical enzyme covalently attaches the methyl group at the 3-pos ...

Nonstoichiometric Low-Temperature Grown GaAs Nanowires

Anna Fontcuberta i Morral, Federico Matteini, Gözde Tütüncüoglu, Heidi Andrea Potts, Tao Xu

The structural and electronic properties of nonstoichiometric low-temperature grown GaAs nanowire shells have been investigated with scanning tunneling microscopy and spectroscopy, pump probe reflectivity, and cathodoluminescence measurements. The growth o ...

Hydrogen-activating models of hydrogenases

Xile Hu, Tao Xu, Dafa Chen

Hydrogenases are biological catalysts for hydrogen evolution and activation. While many model complexes of hydrogenases can catalyze the hydrogen evolution reaction, few of them can react with hydrogen. Here we review the hydrogen-activating models of hydr ...

Copper-Catalyzed 1,2-Addition of alpha-Carbonyl Iodides to Alkynes

Xile Hu, Tao Xu

beta,gamma,-Unsaturated ketones are an important class of organic molecules. Herein, copper catalysis has been developed for the synthesis of --unsaturated ketones through 1,2-addition of -carbonyl iodides to alkynes. The reactions exhibit wide substrate s ...

Reconstitution of [Fe]-hydrogenase using model complexes

Xile Hu, Matthew Wodrich, Tao Xu, Dafa Chen

[Fe]-Hydrogenase catalyses the reversible hydrogenation of a methenyltetrahydromethanopterin substrate, which is an intermediate step during the methanogenesis from CO2 and H-2. The active site contains an iron-guanylylpyridinol cofactor, in which Fe2+ is ...

Iron- Catalyzed 1,2-Addition of Perfluoroalkyl Iodides to Alkynes and Alkenes

Xile Hu, Chi Wai Cheung, Tao Xu

Iron catalysis has been developed for the intermolecular 1,2-addition of perfluoroalkyl iodides to alkynes and alkenes. The catalysis has a wide substrate scope and high functional-group tolerance. A variety of perfluoroalkyl iodides including CF3I can be ...

Modelling the time-dependent rheological behaviour of heterogeneous brittle rocks

Jian Zhao, Tao Xu, Michael Heap

A 2-D numerical model for brittle creep and stress relaxation is proposed for the time-dependent brittle deformation of heterogeneous brittle rock under uniaxial loading conditions. The model accounts for material heterogeneity through a stochastic local f ...

Parallel computation for debonding process of externally FRP plated concrete

Jian Zhao, Tao Xu

In this paper, the three dimensional Parallel Realistic Failure Process Analysis (RFPA(3D)-Parallel) code based on micromechanical model is employed to investigate the bonding behavior in FRP sheet bonded to concrete in single shear test. In the model, the ...
