Experimentally, Ce2O3 films are used to study cerium oxide in its fully or partially reduced state, as present in many applications. We have explored the space of low energy Ce2O3 nanofilms using structure prediction and density functional calculations, yielding more than 30 distinct nanofilm structures. First, our results help to rationalize the roles of thermodynamics and kinetics in the prep...

The diverse abilities of cerium oxide nanoparticles (CONPs) have encouraged researchers to pursue CONPs as a therapeutic agent to treat a number of diseases, including cancer. In vitro and in vivo studies have shown CONPs to be toxic to cancer cells, inhibit invasion, and sensitize cancer cells to radiation therapy. However, CONPs display minimal toxicity to normal tissues and provide protectio...

In this paper, rotating bending fatigue tests of 2024-T4 Al alloy with different oxide coatings were carried out. Compared to the uncoated and previously reported oxide coatings of aluminum alloys, the fatigue strength is able to be enhanced by using a novel oxide coating with sealing pore technology. These results indicate that the better the coating surface quality is, the more excellent the ...

In this study, ternary mixed metal oxide (Ce2O3/La2O3/Fe3O4) catalysts were synthesized for reduction of SO2 to sulfur by CH4. The response surface method (RSM) was used to optimize the synthesis conditions. The XRD, FESEM, BET, BJH, EDX and NH3-TPD analyses were performed to characterize the synt...

Phosphating is one of the most widely used surface treatments of ferrous and non-ferrous materials due to its low-cost, easy production, good corrosion resistance and good adhesion with paint. Many researchers have tried to explore the different applications of the phosphating processes in various fields including automobile and aerospace. Recently, the zinc phosphate conversion coatings on mag...

The corrosion behaviour of αand β-Ta coatings was compared to that of Cr coatings produced by cylindrical magnetron sputtering as well as electrodeposition. For Ta coatings, the corrosion process was dominated by dissolution of the steel substrate through open pores, however, at the end of 5 days, coating degradation was not observed. In contrast, while open pores were not observed with the Cr ...

The fully-leaky guided wave technique has been used to study the reflective 90 ̊ MTN liquid crystal cell used for LCOS. The cell is comprised of upper substrate with indium-tin-oxide coating and lower substrate with aluminum coating. Reflective angle-dependent signals (Rss, Rpp, Rsp and Rps) were recorded over a range of angles of incidence with the cell under application of 0 7 Vrms ac electric...
