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).
On July 20, 2015, Ling was expelled from the Communist Party of China, and was arrested to face criminal proceedings. 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.
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.
The controlled exfoliation of hexagonal boron nitride (h-BN) into single- or few-layered nanosheets remains a grand challenge and becomes the bottleneck to essential studies and applications of h-BN. Here, we present an efficient strategy for the scalable synthesis of few-layered h-BN nanosheets (BNNS) using a novel gas exfoliation of bulk h-BN in...
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.

For Wang, suona music runs in his blood. Yet even with four generations of suona players among his forebears, it took him years of practice to master even the basics on the notoriously difficult instrument. As a child, he spent months playing cymbals in his grandfather’s band to improve his sense of rhythm. Then, from the age of 8, he started learning the sheng mouth organ to perfect his intonation and dropped out of school to focus on music.
A facile approach to bimetallic phosphides, Co-Fe-P, via high-temperature (300 °C) reaction between Co-Fe-O nanoparticles and trioctylphosphine is presented. The growth of Co-Fe-P from the Co-Fe-O is anisotropic. As a result, Co-Fe-P nanorods (from the polyhedral Co-Fe-O nanoparticles) and sea-urchin-like Co-Fe-P (from the cubic Co-Fe-O nanoparticl...
The suona is a traditional Chinese wind instrument similar to the oboe that is customarily played alongside gongs, drums, and the sheng mouth organ at weddings and funerals in rural northeastern China. In Shandong province, where the suona is sometimes known by the onomatopoeic name “wulawa,” the instrument is an integral part of traditional culture. But in Shandong’s Pingyi County, where Wang hails from, suona performances have been banned from funerals since October 2016 as part of local government reforms aiming to curb lavish, showy ceremonies.
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...
