Photoionization of the Ce Ce process has been studied using the random phase approximation with exchange method in the energy region 100-150 eV. Comparison of our results with the recent measurement [Müller et al, Phys. Rev. Lett. 101, 133001 (2008)] confirms the suppression effect of the carbon cage in the endohedral fullerene Ce@C+82 photoionization. The reasons for the cause of the confineme...

In this paper, a high-efficiency and stable Cu-Ce@?-Al2O3 catalyst was prepared by taking the reverse osmosis (RO) concentrated water of sewage treatment plant as object activated alumina carrier. The preparation factors that affected catalytic activity were investigated. SEM, EDS, XRD, BET, XRF, XPS techniques applied to characterize catalyst. Optimal working conditions, degradation mechanism ...

As renewable energy source integration increases, P2G technology that can store surplus power as methane is expected to expand. The development of a CO2 methanation catalyst, one the core processes concept, being actively conducted. In this work, low-rank coal (LRC) was used catalyst support for methanation, it potentially enhance diffusion and adsorption behavior by easily controlling pore str...

Résumé— Une phase primordiale lors de la modélisation d’un système à l’aide d’un perceptron multicouches reste la détermination de la structure du réseau. Dans ce cadre, nous proposons un algorithme d’élagage du réseau basé sur l’utilisation de l’analyse de la variance de la sensibilité de tous les paramètres du réseau. Cet algorithme sera testé sur deux exemples de simulation et ses performanc...

Novel K-promoted bimetallic Fe- and In-based catalysts on a Ce? ZrO2 support were prepared tested for higher alcohol synthesis from CO2 hydrogen. The FeIn/Ce?ZrO2 precursors with different Fe contents characterized in detail, well-dispersed Fe2O3 In2O3 phases oxygen vacancies observed. continuous setup at extended times stream (up to 100 h) 300 °C, 10 MPa, gas hourly space velocity of 4500 mL g...

An efficient one-pot synthesis of 1,2,3-triazole derivatives of dihydropyrimidinones has been developed using two multicomponent reactions. The aldehyde-1,2,3-triazoles were obtained in good yields from in situ-generated organic azides and O-propargylbenzaldehyde. The target heterocycles were synthesized through the Biginelli reaction in which the aldehyde-1,2,3-triazoles reacted with ethyl ace...

We present a novel labeling technique for detection and speciation of organochloride compounds using microcapillary zone electrophoresis coupled with laser induced fluorescence detection. Organochloride compounds in an aqueous mixture are conjugated with glutathione using 1,5 Diazabicyclo [4.3.0] non-5-ene as a catalyst. The conjugated species are then labeled with Pacific Blue succinimidyl est...

Abstract This work aimed to study the preparation of cerium oxide (CeO 2 ) used as catalyst for biodiesel production from palm oil. The precipitation method was in synthesis. effects oxalic concentrations and stirring rates process were investigated. Oxalic acid added into (Ce) ethylenediaminetetraacetic solution form Ce oxalate before calcined obtain CeO . results showed that slightly affect m...

Metal?nitrogen?carbon materials (M-N-C) have attracted much attention due to their low cost, high abundance, and efficient catalytic performance. Nevertheless, Fe-N-C are considered the most promising oxygen reduction reaction (ORR) catalysts for replacing noble metals. Ce is chemically active has many metal valence states, empty orbitals that can participate in coordination. On this basis, Fe,...
