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...
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...
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.
Ling began his career as a functionary in regional branches of the Communist Youth League in his native Shanxi Province. His Youth League involvement propelled him to the national-level organization in 1979. At the Youth League Ling worked in its propaganda department and edited its flagship newspaper. Closely following the footsteps of his patron Hu Jintao, Ling was promoted to a leadership position in the General Office of the Communist Party of China in 1999, and became an important member of the State Commission for Public Sector Reform.
Several weeks prior to the announcement of the investigation, Ling continued to make appearances on state television in his positions of CPPCC Vice Chairman and United Front chief. On December 15 Ling had penned an article on the Communist theory publication Qiushi brimming with praise for the signature political philosophies of Xi Jinping such as the "Chinese Dream". This was seen by observers as a 'last-ditch' declaration of fealty to the new Chinese leader with whom Ling was thought to have lost favour.[11]
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...

But that imbalance can build resentment. In France, the secretary of the Academie Française called last December for a “reconquest of the French language” from loanwords; in China, government-friendly papers printed screeds this spring against “Wi-Fi,” “VIP,” and “e-mail.” Even as many governments work to protect languages from the spread of English, however, speakers in those countries go blithely off to “hot jooga,” meaning that official policy and the daily reality of English may be very different things.
Li Bingxiang, a suona fan and former Party secretary of a village in Pingyi County, also believes the instrument has fallen victim to the wide net cast to prevent ostentatious funerals. “The main extravagant expenses are the banquet, coffin, and labor costs for a three-day ceremony,” Li says. “There should be a compromise that reaches the government’s goals but also preserves traditions.”
Taming interfacial electronic effects on Pt nanoparticles modulated by their concomitants has emerged as an intriguing approach to optimize Pt catalytic performance. Here, we report Pt nanoparticles assembled on vacancy-abundant hexagonal boron nitride nanosheets and their use as a model catalyst to embrace an interfacial electronic effect on Pt in...
