    An interior penalty approach to a large-scale discretized obstacle problem with nonlinear constraints

    We propose an interior penalty method to solve a nonlinear obstacle problem arising from the discretization of an infinite-dimensional optimization problem. An interior penalty equation is proposed to approxim...

    Electrochemical Proton Reductions Catalyzed by the Simpler Hexacoordinate Iron Compounds as Functional Mimics of the Active Site in [FeFe] Hydrogenase

    Ligand-substitution reaction of [(μ-S2C4N2H2)Fe2(CO)6] (1) generated a normal mono-substituted diiron dithiolate derivative [(μ-S2C4N2H2)Fe2(CO)5(PMe3)] (1P) and a simpler hexacoordinate mononuclear compound [(μ-...

    Influence of the methylene group between azadithiolate nitrogen atom and phenyl moiety on the protophilic properties of [FeFe]-hydrogenase model complexes

    An [FeFe]-hydrogenase mimic 4 with functional benzyl moiety covalently linked to the azadithiolate ligand was synthesized. The structure, protonation, and electrochemical properties of 4 and a phenyl substituted ...

    An artificial [FeFe]-hydrogenase mimic with organic chromophore-linked thiolate bridges for the photochemical production of hydrogen

    An artificial [FeFe]-hydrogenase ([FeFe]-H2ase) mimic 3II, consisting of dual organic chromophores covalently assembled to the [Fe2S2] active site, was constructed for light-driven hydrogen evolution. The structu...
