Water exchange studies of lanthanide complexes and aqua ions

Shima Karimi

Complexes of lanthanide (III) ions have been used in structural studies of biomolecules and as contrast agents (CA). Clinically approved CAs have only one water molecule in their first coordination sphere. Structure and water exchange rate of these complex ...

Grafting submicron titania particles with gold nanoparticles using droplet microfluidics

Martinus Adela Maria Gijs, Virendra Kumar Parashar, Josias Basil Wacker

A microfluidic method to synthesize gold–titania nanocomposites is presented. Porous TiO2 particles are first loaded with a reducing agent and then suspended in water and mixed with chloroauric acid (HAuCl4) in a droplet-by-droplet manner on a microfluidic ...

Tetraalkylammonium Salts of Weakly Coordinating Aluminates: Ionic Liquids, Materials for Electrochemical Applications and Useful Compounds for Anion Investigation

Michael Graetzel, Mingkui Wang, Ines Raabe

In this study, we investigated the tetraalkylammonium salts of the weakly coordinating fluorinated alkoxyaluminates pftb (Al(O(C(CF3)(3))(4)) hfip (Al(OC(H)-(CF3)(2))(4)) and hftb (Al(OC(CH3)(-) (CF3)(2))(4)) in order to obtai ...

Selective Formic Acid Decomposition for High-Pressure Hydrogen Generation: A Mechanistic Study

Paul Joseph Dyson, Gabor Laurenczy, Ning Yan, Céline Fellay

A homogenous catalytic system has been developed that efficiently and selectively decomposes formic acid into hydrogen and carbon dioxide. [Ru(H2O)6]2+, [Ru(H2O)6]3+ and RuCl3·xH2O are all excellent precatalysts in presence of TPPTS (TPPTS=meta-trisulfonat ...

17O nuclear quadrupole coupling constants of water bound to a metal ion: A gadolinium(III) case study

Lothar Helm, Oleg Yazyev

Rotational correlation times of metal ion aqua complexes can be detd. from 17O NMR relaxation rates if the quadrupole coupling const. of the bound water oxygen-17 nucleus is known. The rotational correlation time is an important parameter for the efficienc ...
