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).
SHANDONG, East China — The unmistakable wail of the suona pierces the dusk in the village as Wang Ruiyong plays a traditional tune on the double-reed instrument. The elderly funeral attendees approve, recognizing the melody. Yet for nearly five years now, Wang and other suona masters have been recording their repertoire in the fear that the songs could soon be forgotten as their tradition increasingly comes under threat.
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...
“It’s quite hard for us to find jobs,” Wang says. “We’re not young, and we don’t have other skills.” When he first started doing short-term construction work earlier this year, he didn’t even know how to mix concrete, but other workers were friendly and helped teach him the basics. He doesn’t mind the labor, though it leaves him sore. He feels his cheeks are stiff after days away from the suona — a reminder that he was once a master musician.

CO oxidation is an important reaction both experimentally and industrially, and its performance is usually dominated by the surface charge state. For example, CO oxidation on platinum (Pt) surface requires a proper charge state for the balance of adsorption and activation of CO and O2. Here, we present a “Mott−Schottky modulated catalysis” on Pt na...

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...

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...


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.
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...

On February 13, 2004, Yuntai Mountain as the fifth in the world, the third in the country China, was named the world's first World Geopark by UNESCO and caused attention at home and abroad. Meanwhile, Yuntaishan is also a national scenic spot, National Civilized Scenic Area, the first national AAAAA-level scenic spot, national natural heritage, national forest parks, national macaque nature reserve. Yuntain Mountain also has Asia's highest head drop waterfall.
Ling is married to Gu Liping (谷丽萍), the former director-general of Youth Business China a non-profit program that aims to promote youth entrepreneurship that is headquartered in Beijing. In 2010 she was deputy director of the Ying Public Interest Foundation, a charity sponsored by the Communist Youth League. In that role she reportedly solicited donations for the foundation.[13] Gu was thought to be placed in custody prior to the initiation of the investigation on Ling Jihua.

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...

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.
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.”
The sentencing revealed many details which were previously unknown. The conviction stated that Ling had sought to use his influence to advance the interests of senior regional officials Li Chuncheng, Pan Yiyang, and Bai Enpei; all three had fallen under the axe of the anti-corruption campaign though their links to Ling were unclear hitherto the conviction. It also stated that his wife, Gu Liping, and his son, Ling Gu, had taken some bribes on behalf of the Ling family. Ling Gu was said to have solicited bribes worth some 6.5 million yuan (~$1 million) from Wei Xin, a senior executive of Founder Group. Ling and his wife, Gu Liping, additionally were said to have received some 15 million yuan (~$2.3 million) from Guangsha Group, in exchange for political favours from Ling.[21] Following his departure from the General Office, it was said that Ling gained access to privileged state secrets through his former subordinate Huo Ke, who was also indicted and tried.[3]

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]
A simple, solvent-free, solid-state self-assembly strategy for the synthesis of alkaline-metal-oxide-doped mesoporous carbons (MCs) with tunable mesopores (~5-9 nm), high surface-areas (up to 571 m2/g) and large pore volumes (up to 0.65 cm3/g) is developed via the mechanochemical assembly between polyphenol-Ca2+/Mg2+ composites and F127 copolymers....
