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...

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...


Yet some young villagers share the government’s objections to suona funeral performances. To 27-year-old Dong Chengcheng, the funeral reforms are a positive step toward easing the burden on younger generations. “Although the price for booking a suona band is not such a big deal, it still costs money,” he explains. With each funeral typically requiring three days of ceremonies and banquets, the expenses add up — especially as family planning policies have left today’s young people with fewer siblings to share the costs.


In December 1995, after serving in CYL for over ten years, Ling was transferred to General Office of the Communist Party of China, and continued his work in political theory. Between 1994 and 1996 Ling obtained an "on-job master's degree" in commercial management at Hunan University. In June 1998, he was promoted to head of research office of the General Office (中央办公厅调研室主任). In December 1999, Ling was appointed as deputy director of General Office. Later, he also served as the deputy chief of the General Office in charge of the Central Institutional Organization Commission, and chief of staff of the Office of General Secretary Hu Jintao.
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.
Jiaozuo (Chinese: 焦作; pinyin: Jiāozuò [tɕjáu.tswô]; postal: Tsiaotso) is a prefecture-level city in northern Henan province, China. Sitting on the northern bank of the Yellow River, it borders the provincial capital of Zhengzhou to the south, Xinxiang to the east, Jiyuan to the west, Luoyang to the southwest, and the province of Shanxi to the north.Jiaozuo is one of the core cities of the Central Plains urban agglomeration and a regional central city in the Jin-Yu border area.link
The recent reforms are not the first time the suona has been subject to the twists and turns of public policy. In the early days after the Communist victory in 1949, Wang’s family band played the suona not only at weddings and funerals but also at state ceremonies for sending recruits off to military service or starting construction on reservoir projects. Suona music was the soundtrack to every important moment. But during the Great Chinese Famine, no one could afford to hire musicians, and the suona was later blacklisted as part of Cultural Revolution campaigns against Confucian heritage. It wasn’t until the reform and opening-up era in the ’80s that the suona was restored to its central role in northeastern culture.
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...
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...
News of the crash was reported in mainland Chinese media shortly after it happened, but the story was then rapidly suppressed.[8] Reportedly, Ling Jihua, after viewing the body of the driver at the morgue, denied it was his son.[9] Ling was also said to have mobilized staff from the Central Security Bureau, an organ in charge of national leaders' security which reported into the General Office, to cover up the crash.[10] Chinese media also reported that Ling had contacted Zhou Yongkang, then chief of the powerful Central Political and Legal Affairs Commission, to reach unspecified "political deals" in exchange for assistance on covering up the death of his son.[11] Ling then went on to work as normal.[12] In China, Internet search terms such as "Ferrari", "Little Ling" and "Prince Ling" were blocked.[6] In November 2012, an 'exclusive' from the South China Morning Post reported that Jiang Jiemin, a former associate of Zhou Yongkang then serving as chief executive of China National Petroleum Corporation, wired money from the company's accounts to the families of the two women involved in the crash to keep silent about the crash.[5]
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.

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
The stabilization of surfactant-assisted synthesized colloidal noble metal nanoparticles (NPs, such as Au NPs) on solids is a promising strategy for preparing supported nanocatalysts for heterogeneous catalysis because of their uniform particle sizes, controllable shapes, and tunable compositions. However, surfactant removal to obtain clean surface...
It’s not hard to see why governments would seek to defend their languages. But some linguists think a staunch anti-English stance may be counterproductive. Truly endangered languages tend to be encroached on mostly by their dominant geographic neighbors, says Selma Sonntag, a political scientist at Humboldt State University who studies language purist movements: “The threat isn’t from English, it’s from whatever the official language is within their area.” Linguist David Crystal, author of “English as a Global Language,” has written about how Welsh-language purism may be furthering an elitism that prevents younger speakers from adopting the tongue. And it’s worth noting that English owes much of its vitality to its long history of borrowing from French, Latin, Arabic, and pretty much any other language it met. “Loanwords...do alter [a language’s] character—but is this a bad thing?” Crystal told me. “Imagine English without French or Latin loanwords. No Shakespeare, for a start.”
Ling rose to become the Director of the General Office, an organ that handles day-to-day logistics and bureaucratic functions of the Communist Party, in 2007, when Hu was the party's General Secretary (i.e., paramount leader). He was initially seen as a promising candidate for promotion to the top leadership at the 18th Party Congress in 2012. However, his political fortunes abruptly took a turn when his 23-year-old son was killed while driving a Ferrari in 2012, an event that caused embarrassment for the party elite. Ling was then politically sidelined.
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...
