Oxidative stress has increasingly been demonstrated as playing a key role in the biological response induced by nanoparticles (NPs). The acellular cytochrome c oxidation assay has been proposed to determine the intrinsic oxidant-generating capacity of NPs. Yet, there is a need to improve this method to allow a rapid screening to classify NPs in terms of toxicity. We adapted the cytochrome c assay...
The bimetallic Au-M/Fe2O3 catalysts were prepared by deposition coprecipitation method with Au/M atomic ratio of 1. All the catalysts were measured for WGS reaction and characterized by TPR/TPO studies. Ruthenium- and nickel-modified catalysts showed higher WGS activities compared to the other systems including unmodified Au/Fe2O3 at low temperature (100 °C). At higher temperature (240 °C), ruthenium-,...
