Mono-, Di- and Tetra-iron Complexes with Selenium or Sulphur Functionalized Vinyliminium Ligands: Synthesis, Structural Characterization and Antiproliferative Activity

Paul Joseph Dyson, Lucinda Kate Batchelor, Silvia Schoch

A series of diiron/tetrairon compounds containing a S- or a Se-function (2a-d, 4a-d, 5a-b, 6), and the monoiron [FeCp(CO){SeC1(NMe2)(CHC3)-H-2(Me)}] (3) were prepared from the diiron mu-vinyliminium precursors [Fe2Cp2(CO)( mu-CO){mu-eta(1): eta(3)-C-3(R')( ...

Piano Stool Aminoalkylidene-Ferracyclopentenone Complexes from Bimetallic Precursors: Synthesis and Cytotoxicity Data

Paul Joseph Dyson, Lucinda Kate Batchelor

The reaction of pyrrolidine with a series of cationic diiron cyclopentadienyl complexes containing a bridging vinyliminium ligand gives access to piano stool monoiron complexes based on a five-membered metallacycle that includes a vinyl-aminoalkylidene moi ...

Highly efficient dye-sensitized solar cells achieved through using Pt-free Nb2O5/C composite counter electrode and iodide-free redox couples

Ulf Anders Hagfeldt, Weiwei Zhang, Wenyan Li

To improve the catalytic activity of Nb2O5, a composite Nb2O5/C (Nb2O5 imbedded in carbon support) is synthesized with a simple in situ method and then introduced the composite into dye-sensitized solar cells (DSCs) as a counter electrode (CE) catalyst. Ba ...

Bubble electrodeposition of gold porous nanocorals for the enzymatic and non-enzymatic detection of glucose

Sandro Carrara, Irene Taurino

Au nanocorals are grown on gold screen-printed electrodes (SPEs) by using a novel and simple one-step electro-deposition process. Scanning electron microscopy was used for the morphological characterization. The devices were assembled on a three-electrode ...

Influence of the Adsorption of Phycocyanin on the Performance in DSS Cells: and Electrochemical and QCM Evaluation

Michael Graetzel, Jean-David Décoppet, Thomas Moehl

The influence of some coadsorbents and different pH values on the efficiency of DSS cells assembled with phycocyanin was evaluated using quartz crystal microbalance (QCM) and electrochemical techniques as impedance spectroscopy (EIS) and cyclic voltammetry ...

2016

Uranyl(VI), uranyl(V), and uranium(IV) complexes supported by ferrocene-based tetradentate Schiff-base ligands were synthesized, and their solid-state and solution structures were determined. The redox properties of all complexes were investigated by cycli ...

Synthesis of highly effective vanadium nitride (VN) peas as a counter electrode catalyst in dye-sensitized solar cells

Ulf Anders Hagfeldt, Hairun Guo

Vanadium nitride (VN) peas and cubes were synthesized by regulating the molar ratio of the starting materials (urea/VOCl3) via the urea-metal chloride route. The as-prepared VN compounds were subsequently introduced into dye-sensitized solar cells (DSCs) a ...
