One liquidus region, a liquid–CeO 2 two-phase coexisting region, and a liquid–CeO 2 –akermanite three-phase coexisting region were confirmed within the investigated composition ranges. Based on the experimental data and phase compositions, the phase diagram of the CaO-SiO 2 -CeO 2 -10.0wt...
Evaluation of the Effects of Nano-Metal Oxide (Nano- SiO2, Nano-HfO2, Nano-CeO2, Nano-Ta2O5) on Microtox, Algae and Daphnia magna Nano-metal oxides (NMO) are the most used nanomaterials in the industrial sectors as well as in the medicine, in the textile and in the agricultural and ...
Pd/CeO2-cube is much less active than Pd/CeO2-rod, but more active than Pd/SiO2. This shows that there is synergy between the Pd phase and the CeO2(100), although its extent is less than the Pd-CeO2(111) synergy. HR-TEM shows that the surface of Pd/CeO2-cube contains ...

A thermally grown amorphous SiO2 layer provides an electrically and thermodynamically stable material, where the interface of the SiO2 layer with underlying silicon provides a high quality interface as well as superior electrical isolation properties. However, increased scaling and other requirements in ...
In-Situ Studies on the Crystallization of CaO-SiO2-CaF2-CeO2 System by a Confocal Laser Scanning MicroscopeMaterials ScienceThe recovery of rare earth elements from metallurgical slags containing rare earths is an important topic. The crystallization behavior of CaO-SiO 2 -CaF 2 -CeO 2 system ...
Cerium oxide nanoparticles (CeO2 NPs) are favorable in nanotechnology based on some remarkable properties. In this study, the crystalline CeO2 NPs are successfully prepared by an efficient microwave combustion (MCM) and conventional route sol-gel (CRSGM)
However, copper is the most important promoter of hydrogen production on inert supports such as Al2O3, La2O3, SiO2, or ZrO2 [12,13,14], leading to high catalytic activity and good selectivity and yield to H2 [12,13,15,16]. This is attributed to copper acting as an active agent: ...
