Supported CuO-CeO catalysts have been extensively studied for their outstanding catalytic activity in CO oxidation. Unfortunately, they are prone to sintering and deactivation when exposed to high-temperature automotive exhausts. Herein, taking advantage of the heat-resistant SiO microspheres, we fabricated a series of core-shell-structured yCuO- xCeO@SiO ( x is the weight ratio of CeO-SiO and y is the weight ratio of Cu-(CeO@SiO)) composite catalysts.

The fresh samples after air-calcination at 400 °C were tested under the reaction conditions of CO oxidation, and showed the following order of reactivity: CoMnO/CeO > CoO/CeO > MnO/CeO. X-ray diffraction (XRD) and transmission electron microscopy (TEM) data identified that the structure of the CeO support was maintained during deposition of metal (Co, Mn) ions while the corresponding vis-Raman spectra verified that more oxygen vacancies were created after deposition-precipitation than those in pure ceria nanorods.

- Scientists studied a new substance called 7-O-geranylquercetin (GQ) to see how it affects lung cancer cells, specifically two types: A549 and NCI-H1975.
- They found that GQ made cancer cells die without hurting normal lung cells and worked by changing certain proteins important for cell death and survival.
- The study shows that GQ could be a useful treatment for lung cancer because it causes cancer cells to die and promotes another process called autophagy, which helps clean out damaged parts of the cells.
