Mechanism of oxygen reduction by metallocenes near liquid|liquid interfaces

Hubert Girault, Pekka Eero Peljo, Thomas James Stockmann, Haiqiang Deng

The mechanism of the oxygen reduction reaction (ORR) at a liquid|liquid interface, employing ferrocene (Fc) derivatives – such as decamethylferrocene (DMFc) – as a lipophilic electron donor along with sulfuric acid as an aqueous proton source, was elucidat ...

A Biocompatible in Vivo Ligation Reaction and Its Application for Noninvasive Bioluminescent Imaging of Protease Activity in Living Mice

Douglas Hanahan, Aurélien Godinat, Gennady Nikitin, Ke Cheng

The discovery of biocompatible reactions had a tremendous impact on chemical biology, allowing the study of numerous biological processes directly in complex systems. However, despite the fact that multiple biocompatible reactions have been developed in th ...

Factors affecting the development and dynamics of hypoxia in a large shallow stratified lake: Hourly to seasonal patterns

Damien Bouffard

[1] The examination of hypoxia in the hypolimnion of large lakes traditionally focuses on the assessment of its spatial and temporal extent and its effect on water quality. In Lake Erie, hypoxia typically occurs between July and October in the central basi ...

Oxygen and hydrogen peroxide reduction by 1,2-diferrocenylethane at a liquid/liquid interface

Hubert Girault, Pekka Eero Peljo, Fernando Cortes Salazar, Peiyu Ge, Haiqiang Deng

Molecular oxygen and hydrogen peroxide reduction by 1,2-diferrocenylethane (DFcE) was investigated at a polarized water/1,2-dichloroethane (W/DCE) interface. The overall reaction points to a proton-coupled electron transfer (PCET) mechanism, where the firs ...

Nanocomposites containing neutral blue emitting cyclometalated iridium(III) emitters for oxygen sensing

Mohammad Khaja Nazeeruddin, Rosario Scopelliti, Ursula Röthlisberger, Ivano Tavernelli, Basile Curchod, Davide Di Censo

The behavior toward oxygen sensing of nanocomposites made of the aluminum oxide-hydroxide nanostructured solid support (AP200/19) and neutral blue emitting cyclometalated iridium(III) complexes was studied. The results are compared with the same dyes immob ...

Study of the pO2-sensitivity of the dendrimeric and free forms of Pd-meso-tetra(4-carboxyphenyl)porphyrin, incorporated or not in chitosan-based nanoparticles

Hubert van den Bergh, Georges Wagnières, Peter Käuper, Patrycja Nowak-Sliwinska

The concentration of oxygen and its rate of consumption are important factors in certain medical treatments, such as radiotherapy and photodynamic therapy (PDT). Measuring the tissue concentration of oxygen or its partial pressure (pO2) can be achieved by ...

Microstructure of Al95.5Cr2.5Si2(N1-xOx) thin films covering from nitrides to oxides

Alireza Karimi, Hossein Najafi

Al95.5Cr2.5Si2(N1-xOx) thin films were prepared using pulsed DC-magnetron sputtering at 650 degrees C by changing the oxygen to nitrogen ratio (O-2/(O-2 + N-2)) in the reactive gas. The obtained films were characterized by various techniques including XRD, ...

Novel luminescent Ir(III) dyes for developing highly sensitive oxygen sensing films

Michael Graetzel, Mohammad Khaja Nazeeruddin

New sensing films have been developed for the detection of molecular oxygen. These films are based on luminescent Ir(III) dyes incorporated either into polystyrene (with and without plasticizer) or metal oxide, nanostructured material. The preparation and ...

Discovery, structure, and anticancer activity of an iridium complex of diselenobenzoquinone

Paul Joseph Dyson, Anna Katherine Renfrew

Caught in the act: The first stable η4-diseleno-p-benzoquinone complex, [Cp*lr(η4-C6H4Se2)], has been isolated. The X-ray structure confirms the coordination of the elusive diselenobenzoquinone intermediate. The anticancer activity of this complex was comp ...
