Proton-Coupled Oxygen Reduction at Liquid-Liquid Interfaces Catalyzed by Cobalt Porphine

Hubert Girault, Manuel Alejandro Méndez Agudelo, Fengping Li, Imren Hatay, Zdenek Samec

Cobalt porphine (CoP) dissolved in the organic phase of a biphasic system is used to catalyze O2 reduction by an electron donor, ferrocene (Fc). Using voltammetry at the interface between two immiscible electrolyte solutions (ITIES), it is possible to driv ...

Comparison of the denitrification potential of aerobic granules cultivated with acetate and propionate

Christof Holliger, David Gregory Weissbrodt, Samuel Lochmatter, Graciela Gonzalez Gil

Simultaneous nitrification-denitrification has been observed in aerobic granular sludge sequencing batch bubble column reactors fed with either acetate or propionate with elimination rates of up to 60-70%. Several in-situ tests under anoxic conditions were ...

Molecular and biochemical aspects of the chloroethene dehalorespiration process

Christof Holliger, Julien Maillard, Aurélie Duret, Laure Prat

Tetrachloroethene (PCE) is a major groundwater pollutant as a result of extensive use and spillage since 80 years. Several obligate anaerobic bacteria have the ability of using chlorinated aliphatic compounds as terminal electron acceptor in a process call ...

A triphenylamine dye model for the study of intramolecular energy transfer and charge transfer in dye-sensitized solar cells

Ulf Anders Hagfeldt, Ming Liu

A novel dye (2TPA-R), contg. two triphenylamine (TPA) units connected by a vinyl group and rhodanine-3-acetic acid as the electron acceptor, is designed and synthesized successfully to reveal the working principles of org. dye in dye-sensitized solar cells ...

Metals in Proteins: Correlation Between the Metal-Ion Type, Coordination Number and the Amino-Acid Residues Involved in the Coordination

Ivan Dokmanic

Metal ions are constituents of many metalloproteins, in which they have either catalytic (metalloenzymes) or structural functions. In this work, the characteristics of various metals were studied (Cu, Zn, Mg, Mn, Fe, Co, Ni, Cd and Ca in proteins with know ...

Effect of Different Dye Baths and Dye-Structures on the Performance of Dye-Sensitized Solar Cells Based on Triphenylamine Dyes

Ulf Anders Hagfeldt, Rong Zhang

Triphenylamine dyes were designed and synthesized as photosensitizers for dye-sensitized solar cells (DSSCs). Different substituted phenylene units, 2,2';5',2''-ter-thiophene (TT) and dithieno[3,2-b;2',3'-d]thiophene (DTT) serve as the π-spacers - the elec ...

3D-ITIES supported on porous reticulated vitreous carbon

Hubert Girault, Bin Su, Mohamad Hojeij, Nicolas Eugster

A thin aqueous film prepared by layer-by-layer assembly of oppositely charged polypeptides on 4-aminobenzoic acid modified porous reticulated vitreous carbon (RVC) electrodes was used with the aim of forming a 3D-ITIES. The film containing a redox mediator ...

An experimental and computational study on intramolecular charge transfer: a tetrathiafulvalene-fused dipyridophenazine molecule

To study the electronic interactions in donor-acceptor (D-A) ensembles, D and A fragments are coupled in a single molecule. Specifically, a tetrathiafulvalene (TTF)-fused dipyrido[3,2-a:2′,3′-c]phenazine (dppz) compound having inherent redox centers has be ...

Excited-State Dynamics of Donor−Acceptor Bridged Systems Containing a Boron−Dipyrromethene Chromophore: Interplay between Charge Separation and Reorientational Motion

Natalie Renuka Banerji, Eric Vauthey

The excited-state dynamics of a series of electron donor−acceptor bridged systems (DABS) consisting of a boron−dipyrromethene chromophore covalently linked to a dinitro-substituted triptycene has been investigated using femtosecond time-resolved spectrosco ...
