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...
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).
Ling Jihua (Chinese: 令计划; born 22 October 1956) is a former Chinese politician as one of the principal political advisers of former leader Hu Jintao.[1] Ling was best known for his tenure as chief of the General Office of the Communist Party of China between 2007 and 2012. Ling was charged with corruption and sentenced to life imprisonment as part of a larger campaign carried out by Xi Jinping.
On September 1, 2012, prior to the transfer of power between Hu Jintao and Xi Jinping at the pivotal 18th Party Congress, Ling was abruptly transferred from his position as General Office chief to become head of the United Front Work Department, an organ considered to be of less importance. This was seen as a demotion for Ling. At the 18th Party Congress held in the fall of 2012, Ling did not gain a seat on the Politburo as expected, nor did he retain his position as Secretary of the Secretariat; this signalled that Ling was excluded from all the major power organs of the party.[11] In March 2013, Ling was elected as one of the Vice-Chairmen of the Chinese People's Political Consultative Conference (CPPCC), barely holding onto his status as a "national leader". In addition, of the 23 candidates standing for confirmation for the CPPCC Vice-Chairmanship, Ling received, by far, the fewest votes in favour. A total of 90 CPPCC delegates voted against Ling, while 22 delegates abstained.[14]
Controlling nanoparticle (NP) surface strain, i.e. compression (or stretch) of surface atoms, is an important approach to tune NP surface chemistry and to optimize NP catalysis for chemical reactions. Here we show that surface Pt strain in the core/shell FePt/Pt NPs with Pt in 3 atomic layers can be rationally tuned via structure transition of FePt...
It’s a common experience for English speakers abroad: suddenly recognizing a familiar word in a newspaper, or on a billboard, or in a fragment of conversation. Since World War II, English has become by far the leading exporter of “loanwords,” as they’re known, including nearly universal terms like “OK,” “Internet,” and “hamburger.” The extent to which a language loans words is a measure of its prestige, said Martin Haspelmath, a linguist at the Max Planck Institute. English, clearly, is now on top.
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...
NixWO2.72 nanorods (NRs) are synthesized by a one-pot reaction of Ni(acac)2 and WCl4. In the rod structure, Ni(II) intercalates in the defective perovskite-type WO2.72 and is stabilized. The NixWO2.72 NRs show the x-dependent electrocatalysis for the oxygen evolution reaction (OER) in 0.1M KOH with Ni0.78WO2.72 being the most efficient, even outper...
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]

The most successful band in Pingyi County is headed by 29-year-old Liu Ji. In jeans and a tight white T-shirt, with a gleaming stud in his ear, Liu looks the perfect antithesis of Wang, the traditionalist in gray trousers and a loose white shirt. Yet Liu, too, learned to play the suona with a reed and a water basin, he says, practicing through hot summer days until the sweat from his feet soaked prints into the ground. He, too, inherited his band from his family, but he added young acrobats, dancers, singers, and Western instruments.
High-quality graphene flakes have long been desirable for numerous applications including energy storage, printable electronics, and catalysis. In this contribution, we report a green, efficient, facile gas-driven exfoliation process for the preparation of high-quality graphene in large scale. The gas exfoliation process was realized by the interpl...

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.
EUdict (European dictionary) is a collection of online dictionaries for the languages spoken mostly in Europe. These dictionaries are the result of the work of many authors who worked very hard and finally offered their product free of charge on the internet thus making it easier to all of us to communicate with each other. Some of the dictionaries have only a few thousand words, others have more than 320,000. Some of the words may be incorrectly translated or mistyped.
Silicon (Si) has been regarded as next-generation anode for high-energy lithium-ion batteries (LIBs) due to its high Li storage capacity (4200 mA h g−1). However, the mechanical degradation and resultant capacity fade critically hinder its practical application. In this regard, we demonstrate that nanocoating of Si spheres with a 3 nm titanium diox...
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...
Chinese is an imperial language that has always loaned more than it borrowed. In the Max Planck Institute’s World Loanword Database, Mandarin Chinese has the lowest percentage of borrowings of all 41 languages studied, only 2 percent. (English, with one of the highest, has 42 percent.) In part because of the difficulty of translating alphabet-based languages into Chinese characters, it’s common to see what are called “calques”—nonphonetic literal translations like “re gou” for “hot dog” or “zhi zhu ren” for “Spiderman.” Despite (or because of) the vast appetite among the Chinese for learning English as a foreign language, Chinese ministers have recently cracked down on loanwords. And yet Chinese people still say “baibai” and “sorry”; “e-mail” is just a lot easier than “dianzi youjian,” the official substitute.

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.

After Wang took over his grandfather’s band in 2007, he felt immense pressure to sustain the reputation and tradition he had inherited, but prospective clients kept asking for new instruments and styles of music. Eventually, Wang caved, learning the electric keyboard and trumpet and recruiting an opera singer. But work continued to dry up, and Wang now often plays with other bands that have navigated the market more shrewdly.

Lanthanum-transition-metal perovskites with robust meso-scale porous frameworks (meso-LaMO 3) are synthesized through use of ionic liquids. The resultant samples demonstrate a rather high activity for CO oxidation, by taking advantage of unique nanostructure-derived benefits. This synthesis strategy opens up a new opportunity for preparing functional mesoporous complex oxides of various compositions.
