A new generation of platinum and iodine free efficient dye-sensitized solar cells

Michael Graetzel, Mohammad Khaja Nazeeruddin, Chenyi Yi, Takeru Bessho, Julien Edouard Frey

We report a series of cobalt complexes with various polypyridyl ligands, where the oxidation potential is tuned from 0.17 to 0.34 V vs. ferrocene. The highest occupied molecular orbitals (HOMO) of the cobalt complexes were stabilized by adding electron acc ...

The electro-deoxidation of dense titanium dioxide precursors in molten calcium chloride giving a new reaction pathway

Duncan Thomas Lindsay Alexander

A new study is presented on the electro-deoxidation of porous TiO2 precursors in molten calcium chlo- ride electrolytes. It is shown that by reducing precursor open porosity from standard values of ≥25% to ∼11–12%, such that there is insufficient free volu ...

Transmission of Alkali Aerosols through Sampling Systems

Christian Ludwig, Tilman J. Schildhauer

In biomass gasification, particles such as condensed alkali salts pose a threat on equipment. Due to high loads of condensable tars in the gases, sampling of these particles to liquids and subsequent analysis of the liquid is frequently the method of choic ...

External control of anodic dissolution mechanism of 100Cr6 in nitrate/chloride mixed electrolytes

Andreas Stephan Lesch, Gunther Wittstock

The anodic dissolution of 100Cr6 steel in neutral electrolytes containing sodium chloride and sodium nitrate was investigated potentiodynamically and galvanodynamically with a rotating disc electrode at room temperature. The total concentration of the mixe ...

An Efficient One-Step Synthesis of Piperidin-2-yl and Pyrrolidin-2-yl Flavonoid Alkaloids through Phenolic Mannich Reactions

Qian Wang

An efficient one-step synthesis of piperidin-2-yl and pyrrolidin-2-yl flavonoid alkaloids was achieved in good to excellent yields by a highly regioselective phenolic Mannich reaction of chrysin with cyclic imines or iminium salts. Performing the reaction ...

Insight from First-Principles Calculations into the Interactions between Hydroxybenzoic Acids and Alkali Chloride Surfaces

Wei Chen

Tuning of effective band gaps at insulator surfaces by adsorbed molecules is of fundamental interest but also technologically relevant for contact charging induced by adsorbed molecules like hydroxybenzoic acids. Our studies by density functional theory of ...

Ammonia oxidation to nitrogen mediated by electrogenerated active chlorine on Ti/PtOx-IrO2

Christos Comninellis, Agnieszka Kapalka, Nina-Luisa Michels

The electrochemical oxidation of ammonia (NH3 and/or NH4+) in the presence of chloride was investigated on a Ti/PtOx-IrO2 electrode. It was shown that ammonia is effectively removed from solution via electrogenerated active chlorine. Based on mass balances ...
