Reduction of NO by CO using Pd–CeTb and Pd–CeZr catalysts supported on SiO_2 and La_2O_3–Al_2O_3

Journal of Environmental Sciences 2015年第1期27卷 87-96页

The catalytic activity of Pd catalysts supported on Ce0.73Tb0.27Ox/SiO2, Ce0.6Zr0.4Ox/Si O2,Ce0.73Tb0.27Ox/La2O3–Al2O3and Ce0.6Zr0.4Ox/La2O3–Al2O3was studied using the reduction of NO by CO. The catalysts were characterized by X-ray fluorescence, surface area, X-ray diffraction, temperature-programmed reduction, CO chemisorption and oxygen storage capacity. Temperature-programmed reduction results indicated that Tb or Zr incorporation improves the reducibility and oxygen storage capacity. CO chemisorption data suggested the presence of large Pd O particles due to the low CO/Pd ratio. No significant differences were obtained in light off temperatures（T Light off） for all Pd catalysts and the most active was1.5%Pd/Ce0.6Zr0.4Ox/SiO2.

Deep excavation of the impact from endogenous and exogenous uncertaintieson long-term energy planning

引用

Energy and AI 2023年第1期11卷 150-160页

作者： Xiang Li François maréchal Industrial Process and Energy Systems Engineering Ecole Polytechnique Fédérale de LausanneRue de l’industrie 17Sion1950Switzerland

Endogenous and exogenous uncertainties exert significant influences on energy planning. In this study,we propose a systematic methodology to excavate the uncertainty space, by combining mix-integer linearprogramming (MILP), Monte Carlo simulation, and machine learning for quantification of the uncertaintyimpacts on a national-level energy system from global and local perspectives. This approach allows in-depthcorrelation analysis highlighting potential synergies and risks in the energy transition, and can be easily applie for assisting policy making. The case study for Switzerland shows that both carbon neutrality (even negativeemissions) and energy autonomy can be achieved by 2050, but the energy system’s configuration variessignificantly under uncertainty. Through conditional distribution analyses, carbon capture and storage (CCS),Photovoltaic (PV), and wood gasification show the most strong correlation for decarbonization. This study isbased on the whole uncertainty space taking into account heterogeneous uncertainties, leading to increasedreliability compared to sensitivity analysis from single scenarios’ comparisons. The synergy between energymodels and artificial intelligence (AI) is promising to be widely applied in energy planning area, particularlyfor emerging technologies with large uncertainty in development.

Provenance of sediments from Barra del Tordo and Tesoro beaches, Tamaulipas State, northwestern Gulf of Mexico

引用

Journal of Palaeogeography 2021年第3期10卷 382-398页

作者： Mayla A.ramos-Vazquez John S.Armstrong-Altrin Posgrado en Ciencias del mar y Limnologpa Universidad Nacional Autonoma de MexicoCiudad UniversitariaCiudad de Mexico 04510Mexico Universidad Nacional Autonoma de Mexico Instituto de Ciencias del Mar y LimnologiaUnidad de Procesos Oceanicos y CosterosCiudad UniversitariaCiudad de Mexico 04510Mexico

The mineralogy, bulk sediment geochemical composition, and U–Pb ages of detrital zircons retrieved from the Barra del Tordo(Tordo) and Tesoro beach sediments in the northwestern Gulf of Mexico were analyzed to determine their provenance. The beach sediments are mainly composed of quartz, ilmenite, magnetite, titanite,zircon, and anorthite. The weathering proxies such as the Chemical Index of Alteration(CIA), Chemical Index of Weathering(CIW), and Plagioclase Index of Alteration(PIA), reveal a moderate-to-high intensity of weathering in the source area. The chondrite-normalized rare earth element(REE) patterns are similar to felsic igneous rocks, with large negative europium anomaly(Eu/Eu^(*)= ~ 0.47–0.80 and ~ 0.57–0.67 in the Tordo and Tesoro beach sediments,respectively).Three major zircon U–Pb age groups are identified in the Tordo and Tesoro beach sediments, i.e., Proterozoic(~2039–595 Ma), Mesozoic(~ 244–70.3 Ma), and Cenozoic(~ 65.9–1.2 Ma). The differences of the zircon age spectrum between the Tordo and Tesoro beach sediments are not significant. The comparison of zircon U–Pb ages in this study with ages of potential source terranes suggests that the Mesozoic and Cenozoic zircons of the studied Tordo and Tesoro beach sediments were derived from the Eastern Alkaline Province(EAP) and Mesa Central Province(MCP). Similarly, the likely sources for the Proterozoic zircons were the Sierra Madre Oriental(SMOr) and Oaxaquia in the northwestern Gulf of Mexico. The results of this study further indicate that the sediments delivered to the beaches by rivers and redistributed by longshore currents were crucial in determining the sediment provenance.

Programmed cell death in seeds of angiosperms

作者： maría Paula López-Fernández Sara Maldonado Laboratory of Plant Development Department of Biodiversity and Experimental Biology Faculty of Exact and Natural Sciences University of Buenos Aires National Research Council of Argentine (CONICET)

During the diversification of angiosperms, seeds have evolved structuralp chemical, molecular and physiolog- ically developing changes that specially affect the nucellus and endosperm. All through seed evolution, programmed celldeath （PCD） has played a fundamental role. However, examples of PCD during seed development are limited. The present review examines PCD in integuments, nucellus, suspensor and endosperm in those representative examples of seeds studied to date.
