Monodisperse 5 nm AuMn nanoparticles were synthesized by hydride reduction of manganese acetylacetonate in the presence of Au nanoparticles. The alloy was formed through fast Mn diffusion into the Au structure. The AuMn nanoparticles were converted to Au-MnO composite particles through air annealing at 170 °C. These Au-MnO particles, especially the...
We report a facile halide ion (Cl(-) or Br(-)) mediated synthesis of Fe nanoparticles (NPs) by thermal decomposition of Fe(CO)5. The NP structure is controlled to be either amorphous (in the absence of halide ions) or single crystalline bcc (in the presence of halide ions). Through systematic investigation on the synthetic conditions, we have confi...
To further enhance catalytic activity and durability of nanocatalysts for oxygen reduction reaction (ORR), we synthesized a new class of 20 nm × 2 nm ternary alloy FePtM (M = Cu, Ni) nanorods (NRs) with controlled compositions. Supported on carbon support and treated with acetic acid as well as electrochemical etching, these FePtM NRs were converte...
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...
Elaborate and sometimes outrageous funeral services featuring everything from strippers to the burning of ghost money drew the attention of international media and local authorities in 2015, but now, even the suona has been caught in the crossfire. In November 2016, 21 professors from prominent institutions like Peking University signed a public appeal for the protection of village funeral traditions, saying that the government reforms ought to allow folk customs in keeping with cultural revival and only forbid extravagant vices such as stripping.
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).

Tailoring the atomic structural configuration at metal and oxide interface offers an effective route for the development of catalysts with optimized properties. Here, we report the design of a unique structural configuration of yolk-shell-like FePt-FeOx nanoparticles (NPs), that exhibits notably enhanced activity and stability towards CO oxidation...
ABSTRACT: This paperexploredhow Chinese civil society organizations (CSOs) had been involved in an adolescent reproductive health policy process and its implications for other developing countries with similar political and social contexts. The case study was the 6th cycle of the Country Program on adolescent reproductive health (Jan. 2006-Dec. 2010). It was a multi-phased, retrospective qualitative study in Guangxi autonomous region. Six categories of policy actors including politician, CSO, policy-maker, health manager, development partner and researcher were interviewed, 34 documents were reviewed and 1 participatory stakeholder workshop was held between Jun. 2007 and Apr. 2008. We focused on different CSOs that had been involved in different stages of the policy process, what strategies they had used to interact with the policy process and how they influenced the content and implementation of the policy. Our results showed that new forms of CSOs in China were emerging, with different mechanisms being used to express their voice and influence the policy process. The involvements of CSOs in the adolescent reproductive health policy process also showed how new opportunities were arising in a rapidly changing Chinese political context, but various factors might affect their involvement in policy process. Critical amongst these were the characteristics of the CSOs, the wider political context of the country and the nature of the policy itself.
