Pt alloy nanowires (NWs) were synthesized and applied as catalysts in the title reaction. The specific activity and mass activity of 2.5 nm wide FePt NWs were higher than of a commercial Pt catalyst. The stability of FePt NWs was tested by scanning the potential in an O(2) -saturated HClO(4) solution. The corresponding polarization curves before an...
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...
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).

Sometimes purism peaks after a war or in a post-colonial situation. South Korea tried to de-Japanify its language after World War II; the Indian and Pakistani governments tried to separate Hindi and Urdu after their partition. A purist approach can also be a smaller language’s way of resisting outside influence. In Iceland, the Icelandic Language Institute preserves the country’s Viking-era language by cobbling together new terms from indigenous roots. Some Native American groups do the same to resist English.
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.
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...
On May 13, 2016, the No. 1 branch of Tianjin Municipal People's Procuratorate filed suit against Ling on behalf of the state at the No. 1 Intermediate People's Court of Tianjin.[20] On July 4, 2016, after a closed-door trial, Ling was sentenced to life imprisonment. He was convicted on charges of taking bribes, illegally obtaining state secrets and abuse of power. Upon hearing his sentence, Ling read aloud from a prepared script stating that he did not contest the conviction and "thanked" the court and the lawyers for their work, and used a Chinese idiom (kegu mingxi) to describe how unforgettable the trial had been to him.
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.

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...
