Monodisperse core/shell FeNiPt/FePt nanowires (4.5 × 20-50 nm) are synthesized by seed-mediated growth of FePt over the pre-made 2.5 nm wide FeNiPt nanowires. The surface profile of the FeNiPt/FePt nanowires is tailored by acid and thermal treatment. The FeNiPt/Pt-skin nanowires show higher activities than the FeNiPt/Pt-skeleton nanowires. © 2015 W...
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...
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...
When England became an empire, English began borrowing less and became the prolific word lender it is today, Haspelmath told me. If we start borrowing again—the way Arabic stopped exporting words to the rest of the world once its empire crumbled and started borrowing more from French and English—we’ll know we’ve seen the apex of our cultural influence. Until then, at least we’ll be able to find a hot yoga class just about anywhere in the world.
Jiaozuo is noted for its blast furnaces and machine construction industries. The total GDP of the city in 2017 was 234.28 billion yuan, an increase of 7.4% over the previous year. Among them, the added value of the primary industry was 13.733 billion yuan, up 4.6%; the added value of the secondary industry was 13.841 billion yuan, up 6.7%; the added value of the tertiary industry was 81.143 billion yuan, up 9.1%. The per capita GDP reached 65,936 yuan. The three industrial structures changed from 6.4:59.3:34.3 of 2016 to 5.9:59.5:34.6.link
