This work establishes the primordial role played by support’s nature when aimed at constitution of Ni2P active phases for supported catalysts. Thus, carbon dioxide reforming methane was studied over three novel catalysts on Al2O3, CeO2 and SiO2-Al2O3 oxides. The catalytic performance, shown catalysts’ series, decreased according to sequence: Ni2P/Al2O3 > Ni2P/CeO2 Ni2P/SiO2-Al2O3. depleted C...

A Ni60 cladding layer with addition of 6.0% CeO2 was prepared on 35CrMoV steel by laser technology. The sample placed at 500 °C, 600 °C and 700 for 60 min to explore the effects heat treatment tribological properties composite coating. microstructure, phase composition, microhardness coating were characterized optical microscopy scanning electron (SEM), X-ray diffraction (XRD), micro-Vickers ha...

BACKGROUND Hepatic ischemia reperfusion is one the main causes for graft failure following transplantation. Although, the molecular events that lead to hepatic failure following ischemia reperfusion (IR) are diverse and complex, previous studies have shown that excessive formation of reactive oxygen species (ROS) are responsible for hepatic IR injury. Cerium oxide (CeO2) nanoparticles have been...

We report a detailed study of the grain orientations and grain boundary (GB) networks in Y2O3 films grown on Ni-5 at.%W substrates. Electron back scatter diffraction (EBSD) exhibited different GB misorientation angle distributions, strongly decided by Y2O3 films with different textures. The subsequent yttria-stabilized zirconia (YSZ) barrier and CeO2 cap layer were deposited on Y2O3 layers by r...

OBJECTIVES With recent advances in nanoparticle manufacturing and applications, potential exposure to nanoparticles in various settings is becoming increasing likely. No investigation has yet been performed to assess whether respiratory tract exposure to cerium oxide (CeO2) nanoparticles is associated with alterations in protein signaling, inflammation, and apoptosis in rat lungs. METHODS Spe...

BACKGROUND Cerium oxide nanoparticles (CeO2) have been shown to be a novel therapeutic in many biomedical applications. Gold (Au) nanoparticles have also attracted widespread interest due to their chemical stability and unique optical properties. Thus, decorating Au on CeO2 nanoparticles would have potential for exploitation in the biomedical field. METHODS In the present work, CeO2 nanoparti...

In the present work, the effect of several parameters involved in the preparation of PdCe-HMOR catalysts active for NOx selective catalytic reduction with methane (NOx CH4-SCR) was studied. Results show that the catalytic performance of Pd-HMOR is better when palladium is introduced by ion-exchange, namely at room temperature. It was also shown that Pd loading does not influence the formation o...

The effects of strong interactions between Ti and ceria on the structures of Ti/CeO2(111) are systematically investigated by density functional theory calculation. To our best knowledge, the adsorption energy of a Ti atom at the hollow site of CeO2 is the highest value (-7.99 eV) reported in the literature compared with those of Au (-0.88--1.26 eV), Ag (-1.42 eV), Cu (-2.69 eV), Pd (-1.75 eV), ...

In the pursuit of stable, high performance Ni-based oxygen evolution reaction (OER) electrocatalysts, modifying local chemical compositions or fabricating hybrid nanostructures to generate abundant interfaces for improving water oxidation activity electrocatalysts has emerged as an effective strategy. Herein, we report facile development a Ni3S2-CeO2 nanostructure via electrodeposition method. ...
