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...
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...
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.

Ling was one of the highest-profile targets (next to Zhou Yongkang and Xu Caihou) of the anti-corruption campaign following the 18th Party Congress spearheaded by Party General secretary Xi Jinping and central discipline chief Wang Qishan. He was the second sitting "national leader"-level figure to be investigated by the party's anti-graft agency, after CPPCC Vice-Chairman Su Rong. Chinese-language media have linked Ling to a mysterious political network composed of prominent politicians and businesspeople with origins in Shanxi called the Xishan Society.[16]
Stabilizing transition metals (M) in MPt alloy under acidic conditions is challenging, yet crucial to boost Pt catalysis toward oxygen reduction reaction (ORR). We synthesized ∼9 nm hard-magnet core/shell L10-CoPt/Pt nanoparticles with 2–3 atomic layers of strained Pt shell for ORR. At 60°C in acid, the hard-magnet L10-CoPt better stabilizes Co (5%...
Though it has banned the suona from funerals, the local government has also paradoxically launched several initiatives to preserve the suona tradition. Since 2014, it has funded research and documentation of suona music, as well as an intangible cultural heritage protection plan that pairs around 15 masters with students. It also offers suona musicians performance opportunities. But according to Liu, the gigs are too few and too poorly compensated — some only pay 800 to 1,000 yuan ($120 to $150) for an eight-person band. He doesn’t believe that a state-sponsored imitation of the master-apprentice method will be able to sustain the tradition.
Highly active, low-cost, and durable electrocatalysts for the water oxidation reaction are pivotal in energy conversion and storage schemes. Here we report the nitride-core, oxide-shell-armor structured FeCoNi oxynitride as an efficient oxygen evolution electrocatalyst with a homogeneously nitride (Fe0.70Co0.56Ni0.92N1.0O0.06) core and oxide (Fe0.4...
As a teenager in the 1980s, Wang would play several gigs a day with his grandfather’s band. Everywhere they performed, they were served tea and tobacco and treated as honored guests. But after the arrival of the new millennium, the popularity of suona music declined. The market for musicians shrank as newlyweds turned to new trends: Western rock bands, pop singers, folk operas. The suona became passé, even maudlin. “Once the suona sounded, people would think someone must have passed away,” Wang explains.
On July 20, 2015, Ling was expelled from the Communist Party of China,[17] and was arrested to face criminal proceedings.[18] Ling's case received significant media attention, since he was the most prominent political figure expelled from the party since criminal proceedings were initiated against former Politburo Standing Committee member Zhou Yongkang. In the party's disciplinary dossier against Ling, he was accused of "violating political discipline, violating political rules, violating organizational discipline, and violating confidentiality discipline." He was further accused of taking in large bribes, aiding in the business interests of his wife, sexual misconduct with "numerous women", and illegally obtaining party and state secrets.[19]
THERE’S NOTHING LIKE visiting Finland to make an English-speaker appreciate the value of words borrowed from other languages. Finnish, as I learned during a trip earlier this month, is an agglutinative language, in which parts of words stay distinct instead of fusing together. This makes for very long words, like “kahdenneksikymmenenneksiyhdeksänneksi” (one way to say “29,” according to my guidebook), and considerable bewilderment for a visitor. To me, it might as well have been Klingon, only with more umlauts. Every now and then, though, a light would shine through the darkness: I’d catch something like “hot jooga” or “muffensi” or “grill maisteri,” and sigh with relief.
The importance of porous carbon as the support material is well recognized in the catalysis community, and it would be even more attractive if several characteristics are considered, such as the stability in acidic and basic media or the ease of noble metal recovery through complete burn off. Because it is still difficult to obtain constant propert...
