Carbon Dioxide to Methanol: The Aqueous Catalytic Way at Room Temperature

Gabor Laurenczy, Katerina Stefania Sordakis

Carbon dioxide may constitute a source of chemicals and fuels if efficient and renewable processes are developed that directly utilize it as feedstock. Two of its reduction products are formic acid and methanol, which have also been proposed as liquid orga ...

Iridium(I)/N-Heterocyclic Carbene Hybrid Materials: Surface Stabilization of Low-Valent Iridium Species for High Catalytic Hydrogenation Performance

David Lyndon Emsley, David Benjamin Roger Antoine Gajan

An Ir-I(NHC)-based hybrid material was prepared using a methodology which allowed the precise positioning and isolation of the Ir centers along the pore channels of a silica framework. The full characterization of the material by solid-state NMR spectrosco ...

Anticancer Organometallic Osmium(II)-p-cymene Complexes

Paul Joseph Dyson, Rosario Scopelliti, Patrycja Nowak-Sliwinska, Catherine Marie Amélie Clavel, Emilia Paunescu

Osmium compounds are attracting increasing attention as potential anticancer drugs. In this context, a series of bifunctional organometallic osmium(II)-p-cymene complexes functionalized with alkyl or perfluoroalkyl groups were prepared and screened for the ...

NanoSIMS analysis of an isotopically labelled organometallic ruthenium(II) drug to probe its distribution and state in vitro

Paul Joseph Dyson, Anders Meibom, Kai Johnsson, Graham Knott, Stéphane Laurent Escrig

The in vitro inter-and intra-cellular distribution of an isotopically labelled ruthenium(II)-arene (RAPTA) anti-metastatic compound in human ovarian cancer cells was imaged using nano-scale secondary ion mass spectrometry (NanoSIMS). Ultra-high resolution ...

Homogenous catalytic hydrogenation of bicarbonate with water soluble aryl phosphine ligands

Paul Joseph Dyson, Gabor Laurenczy, Katerina Stefania Sordakis

The chemical transformation of CO2 and bicarbonates into useful products becomes increasingly impor- tant as the atmospheric CO2 level has reached 400 ppm. Here a small library of sulfonated aryl mono- phosphines and aryl diphosphines was tested as stabili ...

Cationic Iridium(III) Complexes with Two Carbene-Based Cyclometalating Ligands: Cis Versus Trans Isomers

Michael Graetzel, Mohammad Khaja Nazeeruddin, Rosario Scopelliti

A series of cationic iridium(III) complexes with two carbene-based cyclometalating ligands and five different NN bipyridine and 1,10-phenanthroline ancillary ligands is presented. For the first time in the frame of a rarely studied class of bis(heterole ...

Exfoliation of layered double hydroxides for enhanced oxygen evolution catalysis

Xile Hu, Fang Song

The oxygen evolution reaction is a key reaction in water splitting. The common approach in the development of oxygen evolution catalysts is to search for catalytic materials with new and optimized chemical compositions and structures. Here we report an ort ...

Evaluation of the in vitro anticancer activity of cyclometalated half-sandwich rhodium and iridium complexes coordinated to naphthaldimine-based poly(propyleneimine) dendritic scaffolds

Paul Joseph Dyson, Catherine Marie Amélie Clavel, Fabio Edafe

The development of cyclometalated rhodium and iridium complexes from first-and second-generation naphthaldimine-based poly(propyleneimine) dendrimer scaffolds of the type, DAB-(NH2)(n) (where n = 4 or 8, DAB = diaminobutane) has been accomplished. Four met ...

Gold-Free Ternary III-V Antimonide Nanowire Arrays on Silicon: Twin-Free down to the First Bilayer

Sonia Conesa Boj

With the continued maturation of III-V nanowire research, expectations of material quality should be concomitantly raised. Ideally, III-V nanowires integrated on silicon should be entirely free of extended planar defects such as twins, stacking faults, or ...
