Effects of Fe2O3 addition and mechanical activation on thermochemical heat storage properties of the Co3O4/CoO system

Effects of Fe2O3 addition (2-20 wt%) with 1 h mechanical activation on redox reactions of Co3O4 were studied by TG/DSC, SEM, and XRD analyses. The results showed that a Fe2O3 addition from 2 to 15 wt% increases the oxygen release from 1.4 to 3.4 wt% and decreases the reduction onset temperature from 1030 to 960 °C, while it increases the oxygen uptake value and re-oxidation onset temperature re...

Thermochemical Heat Storage Properties of Co3O4-X wt % Al2O3 and Co3O4-X wt % Y2O3 Composites (X=1, 2, 5, 8, 10)

The effect of Al2O3 (1-10 wt %) and Y2O3 (1-10 wt %) additions on thermochemical heat storage properties of Co3O4/CoO system was investigated by thermogravimetry, XRD, and SEM analyses. Results showed that the addition of Al2O3 to Co3O4 at constant 8 h mechanical activation improved the...

Noble metal ionic catalysts.

Because of growing environmental concerns and increasingly stringent regulations governing auto emissions, new more efficient exhaust catalysts are needed to reduce the amount of pollutants released from internal combustion engines. To accomplish this goal, the major pollutants in exhaust-CO, NO(x), and unburned hydrocarbons-need to be fully converted to CO(2), N(2), and H(2)O. Most exhaust cat...

Lysosomal Oxidative Stress Cytotoxicity Induced By Para-phenylenediamine Redox Cycling In Hepatocytes

It has already been reported that muscle necrosis induced by various phenylenediamine derivatives are correlated with their autoxidation rate. Now in a more detailed investigation of the cytotoxic mechanism using a model system of isolated hepatocytes and ring-methylated structural isomer durenediamine (DD) we have shown that under aerobic conditions, phenylenediamine induced cytotoxicity and R...
