| 1 | Nickel ferrite spinel as catalyst precursor in the dry reforming of methane:Synthesis,characterization and catalytic properties显示文摘Dry reforming of methane by CO2 using nickel ferrite as precursor of catalysts was investigated.Nickel ferrite crystalline particles were prepared by coprecipitation of nitrates with NaOH or ammonia followed by calcination,or by hydrothermal synthesis without calcination step.The textural and structural properties were determined by a number of analysis methods,including X-ray diffraction (XRD),Raman spectroscopy and X-ray photoelectron spectroscopy (XPS),among which X-ray diffraction (XRD) was at room and variable temperatures.All synthesized oxides showed the presence of micro or nanoparticles of NiFe2O4 inverse spinel,but Fe2O3 (hematite) was also present when ammonia was used for coprecipitation.The reducibility by hydrogen was studied by temperature-programmed reduction (TPR) and in situ XRD,which showed the influence of the preparation method.The surface area (BET),particle size (Rietveld refinement),as well as surface Ni/Fe atomic ratio (XPS) and the behavior upon reduction varied according to the synthesis method.The catalytic reactivity was investigated using isopropanol decomposition to determine the acid/base properties.The catalytic performance of methane reforming with CO2 was measured with and without the pre-treatment of catalysts under H2 in 650-800 C range.The catalytic conversions of methane and CO2 were quite low but they increased when the catalysts were pre-reduced.A significant contribution of reverse water gas shift reaction accounted for the low values of H2 /CO ratio.No coking was observed as shown by the reoxidation step performed after the catalytic reactions.The possible formation of nickel-iron alloy observed during the study of reducibility by hydrogen was invoked to account for the catalytic behavior. | Rafik Benrabaa Hamza Boukhlouf Axel Lfberg Annick Rubbens Rose-Nelle Vannier Elisabeth Bordes-Richard Akila Barama | 2012 | Journal of Natural Gas Chemistry2012，21，5： | 5 |
| 2 | Diuretic and antioxidant activities of the aqueous extract of leaves of Cassia occidentalis(Linn.) in rats显示文摘Objective: To assess the putative diuretic and antioxidant properties of Cassia occidentalis(C. occidentalis) leaves' aqueous extract. Methods: Adult rats were administered with C. occidentalis leaves aqueous extract acutely(24-h) and subchronically(7 d), at doses 80, 160, 240, 320, and 400 mg/kg(per os). Negative control group received only an equivalent volume of distilled water, while the two positive control groups received the diuretic drugs furosemide(20 mg/kg, i.p.) and hydrochlorothiazide(HCTZ, 20 mg/kg, i.p.). Urinary elimination of electrolytes in response to treatments was evaluated, together with changes in concentrations of creatinine, urea, aldosterone, glucose, and albumin in urine and plasma. Various urinary indicators of kidney function and plasmatic markers of oxidative stress were also assessed. Results: The acute administration of C. occidentalis increased the urinary excretion of 107.58% at the higher dose tested, compared to negative control. The reference drugs furosemide and HCTZ induced increases of 84.27 % and 48.05 %, respectively. Acutely, the extract induced Na+ and Cl- elimination, whereas subchronically an increase in K+ elimination was also observed. The extract also improved the kidney function indexes and oxidative stress markers. These effects were dose-dependent and comparable with positive control observations. Conclusions: Our i ndings strongly suggest that C. occidentalis aqueous extract has diuretic and antioxidant activities, and deserves further studies considering the potential for the treatment of hypertension. | Théophile Dimo Fidèle Ntchapda Joseph Barama David Romain Kemeta Azambou Paul Faustin Seke Etet | 2015 | Asian Pacific Journal of Tropical Medicine2015，8，9： | 2 |
