Evaluation of Protective Coatings for SOFC Interconnects

Chromium poisoning is a widely recognized degradation process in solid oxide fuel cells (SOFC). Stainless steel interconnect plates, in direct contact with the cathode, have been identified as the major chromium source, raising a need for electrically cond ...

Bioavailable copper modulates oxidative phosphorylation and growth of tumors

Johan Auwerx, Douglas Hanahan, Pénélope Andreux, Carole Poitry-Yamate, Seiko Ishida

Copper is an essential trace element, the imbalances of which are associated with various pathological conditions, including cancer, albeit via largely undefined molecular and cellular mechanisms. Here we provide evidence that levels of bioavailable copper ...

Mercury is a direct and potent γ-secretase inhibitor affecting Notch processing and development in Drosophila

Bruno Lemaitre, Patrick Fraering, Mitko Dimitrov, Takayuki Kuraishi, Isabelle Chang

Prenatal exposure to mercury causes neurodevelopmental disorders and neurological pathologies in infants, such as microcephaly and mental retardation. Despite critical importance, the molecular interactions leading to mercury toxicity are yet to be elucida ...

TEM investigation on zirconate formation and chromium poisoning in LSM/YSZ cathode

Jan Van Herle, Aïcha Hessler-Wyser, Antonin Faes, Zacharie Wuillemin, Josef Andreas Schuler

Cell durability is a crucial technological issue for SOFC commercialization, and considerable progress has been made in recent years. A number of degradation pathways have been established, amongst which microstructural changes, poisoning effects and forma ...

Field solar degradation of pesticides and emerging water contaminants mediated by polymer films containing titanium and iron oxide with synergistic heterogeneous photocatalytic activity at neutral pH

César Pulgarin, Félicien Mazille

Photocatalytic degradation of phenol, nalidixic acid, mixture of pesticides, and another of emerging contaminants in water was mediated by TiO2 and iron oxide immobilized on functionalized polyvinyl fluoride films (PVFf-TiO2-Fe oxide) in a compound parabol ...

Sulfur as pollutant species on the cathode side of a SOFC system

Aïcha Hessler-Wyser

Sulfur poisoning in a strontium doped lanthanum cobaltite (LSC) cathode current collection layer was revealed in a solid oxide fuel cell (SOFC) tested in repeat-element and stack configuration. Sources of sulfur contamination, other than trace SOx in air, ...

Physicochemical Properties of the High-Field MRI-Relevant [Gd(DTTA-Me)(H2O)2]− Complex

Lothar Helm, Loïck Moriggi, Cora Prestinari

To study the physicochemical properties of the DTTA chelating moiety (H4DTTA = diethylenetriaminetetraacetic acid = N,N′-[iminobis(ethane-2,1-diyl)]bis[N-(carboxymethyl)glycine]), used in several compounds proposed as magnetic resonance imaging (MRI) contr ...

Highly efficient MRI contrast agents

Loïck Moriggi

Since contrasts agents are used in magnetic resonance imaging (MRI), numerous efforts have been done to increase their relaxivity (parameter allowing to quantify contrast agent efficiency). Few years ago, the Merbach group developed the chelating agent DTT ...

H5EPTPACH2OH: Synthesis, Relaxometric Characterization and 1H NMR Spectroscopic Studies on the Solution Dynamics of Its LnIII Complexes

Lothar Helm, Eva Jakab Toth

The synthesis and characterization of a new metal chelator, 4-(S)-hydroxymethyl-3,6,10-tri(carboxymethyl)-3,6,10-triazadodecanedioic acid (H5EPTPACH2OH), is reported. Protonation constants for the ligand H5EPTPACH2OH and for the previously reported H5EPTPA ...
