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...
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.
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...

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.

He went to the morgue, according to the account I got from one Chinese official, and looked at the body — and then coldly denied that it was his son. He continued to work in the following weeks as if nothing had happened.

Ling had three brothers and one sister. His eldest brother, Ling Fangzhen (令方针), was in the military, and died after a fall while cleaning windows in 1977. Ling's second eldest brother, Ling Zhengce, was a provincial-level politician in Shanxi Province. Zhengce was placed under investigation by the Communist Party's anti-graft agency in June 2014. His sister, Linghu Luxian (令狐路线), was a hospital executive in the city of Yuncheng, and was married to the city's Vice-Mayor Wang Jiankang (王健康); the couple disappeared from public view for several months in 2014, suspected of being placed under investigation, but re-appeared later on. Ling's younger brother Ling Wancheng was a businessman and golf enthusiast, who was initially reported to be detained by the authorities, but later found to have fled to the United States.

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).
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...
