In this communication, we report a facile approach to constructing catalytic active hierarchical interfaces in 1-dimensional (1D) nanostructure, exemplified by the synthesis of TiO2-supported PtFe-FeOx nanowires (NWs). The hierarchical interface, constituting of atomic level interactions between PtFe and FeOx within each NW and the interactions bet...
Fully-ordered face-centered tetragonal (fct) FePt nanoparticles (NPs) are synthesized by thermal annealing of the MgO-coated dumbbell-like FePt-Fe3O4 NPs followed by acid washing to remove MgO. These fct-FePt NPs show strong ferromagnetism with room temperature coercivity reaching 33 kOe. They serve as a robust electrocatalyst for the oxygen reduct...
CO oxidation is an important reaction both experimentally and industrially, and its performance is usually dominated by the surface charge state. For example, CO oxidation on platinum (Pt) surface requires a proper charge state for the balance of adsorption and activation of CO and O2. Here, we present a “Mott−Schottky modulated catalysis” on Pt na...
A simple, solvent-free, solid-state self-assembly strategy for the synthesis of alkaline-metal-oxide-doped mesoporous carbons (MCs) with tunable mesopores (~5-9 nm), high surface-areas (up to 571 m2/g) and large pore volumes (up to 0.65 cm3/g) is developed via the mechanochemical assembly between polyphenol-Ca2+/Mg2+ composites and F127 copolymers....
We report the synthesis of core/shell face-centered tetragonal (fct)-FePd/Pd nanoparticles (NPs) via reductive annealing of core/shell Pd/Fe3O4 NPs followed by temperature-controlled Fe etching in acetic acid. Among three different kinds of core/shell FePd/Pd NPs studied (FePd core at ~8 nm and Pd shell at 0.27, 0.65 or 0.8 nm), the fct-FePd/Pd-0.6...
Sub-10 nm nanoparticles (NPs) of M(II)-substituted magnetite MxFe3-xO4 (MxFe1-xO•Fe2O3) (M = Mn, Fe, Co, Cu) were synthesized and studied as electrocatalysts for oxygen reduction reaction (ORR) in 0.1 M KOH solution. Loaded on commercial carbon support, these MxFe3-xO4 NPs showed the M(II)-dependent ORR catalytic activities with MnxFe3-xO4 being th...
Ling had three brothers and one sister. His eldest brother, Ling Fangzhen (令方针), was in the military, and died after a fall while cleaning windows in 1977. Ling's second eldest brother, Ling Zhengce, was a provincial-level politician in Shanxi Province. Zhengce was placed under investigation by the Communist Party's anti-graft agency in June 2014. His sister, Linghu Luxian (令狐路线), was a hospital executive in the city of Yuncheng, and was married to the city's Vice-Mayor Wang Jiankang (王健康); the couple disappeared from public view for several months in 2014, suspected of being placed under investigation, but re-appeared later on. Ling's younger brother Ling Wancheng was a businessman and golf enthusiast, who was initially reported to be detained by the authorities, but later found to have fled to the United States.

Ling rose to become the Director of the General Office, an organ that handles day-to-day logistics and bureaucratic functions of the Communist Party, in 2007, when Hu was the party's General Secretary (i.e., paramount leader). He was initially seen as a promising candidate for promotion to the top leadership at the 18th Party Congress in 2012. However, his political fortunes abruptly took a turn when his 23-year-old son was killed while driving a Ferrari in 2012, an event that caused embarrassment for the party elite. Ling was then politically sidelined.
A kind of Ti–Fe–Ni–C compound powder was prepared by a novel precursor pyrolysis process using ferro-titanium, carbonyl nickel powder and sucrose as raw materials. The powder had a very compact structure and was uniform in particle size. The TiC–Fe36Ni composite coatings were simultaneously in-situ synthesized by Reactive Detonation-gun Spraying (RDS) using these Ti-Fe-Ni-C compound powders. The coatings presented typical morphology of thermal spraying coatings with two different areas: one was the area of TiC distribution where the round fine TiC particles (from 300nm to 1μm) were dispersed in the Fe36Ni alloy matrix; the other was the area of TiC accumulation (from 2 to 4μm). The surface hardness of the composite coating reached about 94 ± 2(HR15N).
