Two-dimensional(2D)graphitic carbon nitride(g-CN)is a promising anode material for sodium-ion batteries(SIBs),but its insufficient interlayer spacing and poor electronic conductivity impede its sodium storage capacity and cycling ***,we report the fabrication of a fullerene(C_(60))-modified graphitic carbon nitride(C_(60)@CN)material which as an anode material for SIBs shows a high-reversible capacity(430.5 mA h g^(−1) at 0.05 A g^(−1),about 3 times higher than that of pristine g-CN),excellent rate capability(226.6 mA h g^(−1) at 1 A g^(−1))and ultra-long cycle life(101.2 mA h g^(−1) after 5000 cycles at 5 A g^(−1)).Even at a high-active mass loading of 3.7 mg cm^(−2),a reversible capacity of 316.3 mA h g^(−1) can be obtained after 100 *** outstanding performance of C_(60)@CN is attributed to the C_(60) molecules distributed in the g-CN nanosheets,which enhance the electronic conductivity and prevent g-CN sheets from restacking,thus resulting in enlarged interlayer spacing and exposed edge N defects(pyridinic N and pyrrolic N)for sodium-ion ***,a sodium-ion full cell combining C60@CN anode and NVPF@rGO cathode provides high-coulombic efficiency(>96.5%),exceptionally high-energy density(359.8 W h kganode−1 at power density of 105.1 W kganode−1)and excellent cycling stability(89.2%capacity retention over 500 cycles at 1Aganode−1).This work brings new insights into the field of carbon-based anode materials for SIBs.

Geochronological, Sedimentary, Structural, and Metallogenic Characteristics of Southeast China during the Mesozoic: A General Review

引用

International Journal of Geosciences 2015年第9期6卷 1032-1047页

作者： pengju li Hongying li School of Economics and Management Sichuan University of Science & Engineering Zigong China School of the Earth Sciences and Resources China University of Geosciences Beijing China

The tectonic evolution of Southeast China during Late Mesozoic is a prominent topic. Numerous tectonic models on Late Mesozoic evolution ofSoutheast Chinahave been?published in the past 50 years. We synthesized many up-to-date and precise zircon U-Pb ages, sedimentary strata, and regional structures and discussed the oxygen fugacity of magmas and related ore deposits. We also analyzed the most current tectonic models published by some scholars. A multistage tectonic stress evolution history during Late Mesozoic was constructed, which included the following stages: 1) Early-Middle Jurassic (196 - 175 Ma) extension, in which many bimodal volcanics formed;2) Middle-Late Jurassic (165 - 140 Ma) compression, which generated largescale gneissic granites, garnet-bearing granites, stratigraphic hiatus, and nappe structures;3) Early Cretaceous (140 ± 5 - 120 Ma) extension, which formed weakly deformed or undeformed granites, alkali granites, metamorphic core complexes, graben basins, and basic dike swarms;4) Early Cretaceous (120 - 110 Ma) compression, which generated nappe structures, volcanic hiatuses, and garnet-bearing granites;and 5) Early-Late Cretaceous (110 - 80 Ma) extension, which generated largescale bimodal volcanics, basic dike swarms, alkali granites, and graben basins. The Late Mesozoic tectonic evolution ofSoutheast Chinamay be attributed to the drifting history of the Paleo-Pacific plate. The drifting direction of the Paleo-Pacific plate has changed several times since 140 Ma, which led to major changes in the tectonicphenomena from Jurassic to Cretaceous and to the formation of Late Mesozoic mineral deposits.

Superconductors with reduced dimensionality have been widely explored for their exotic superconducting ***,at the two-dimensional limit,two-monolayer Pb films with two types of structures provide an ideal platform to unveil the underlying superconducting mechanism[Science 324,1314(2009)].Here,by combining scanning tunneling microscopy(STM)with the first-principle calculations,we successfully identify that these two types have different atomic lattice structures with varying stacking phases,which further enables us to calculate the phonon spectrum and electron phonon coupling strength of each *** theoretical calculations are in good agreement with tunneling spectroscopy measurements of the superconducting transition temperatures(T_(c)),which established a correlation between atomic structures and ***,it was observed that the higher T_(c)of these two types also possess higher out-of-plane upper critical magnetic fields(Hc2).These findings will provide important new insights into two-dimensional superconductivity at the atomic level.
