The super-Brownian motion X % in a super-Brownian medium % constructed in DF96a] is known to be persistent (no loss of expected mass in the longtime behaviour) in dimensions one ((DF96a]) and three ((DF96b]). Here we ll the gap in showing that persistence holds also in the critical dimension two. The key to this result is that in any dimension (d 3); given the catalyst, the variance of the proc...

For further resource utilization of solid waste steel slag and the reduction in biodiesel production costs, this study used as a carrier to synthesize CaO-CeO2/slag base catalyst for effective transesterification palm oil into fatty acid methyl esters (FAMEs). The synthesis involved two-step impregnation with nitrate calcium cerium thermal activation at 800 °C 180 min. Then, catalysts’ textural...

The degradation of a high concentration organic pollutants has long been challenge to water restoration, and the development electro-Fenton catalysis offers practical approach solving this problem. In study, novel catalyst, activated fullerene soot-loaded NiO-doped CeO2 (0.4(0.4NiO-CeO2)-AFS) nanoparticles, was prepared through impregnation 0.4NiO-CeO2 particles soot (AFS). When applied for 200...

Finding a robust catalytic system for hydrogen production via dry reforming of methane (DRM) remains challenge. Herein, MNi0.9Zr1−xYxO3 (M = Ce, La, and La0.6Ce0.4; x 0.00, 0.05, 0.07, 0.09) catalyst was prepared by the sol–gel method, tested DRM characterized surface area porosity, X-ray diffraction, H2-temperature programmed reduction, thermogravimetry, transmission electron microscopy. In La...
