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).
Highly active, low-cost, and durable electrocatalysts for the water oxidation reaction are pivotal in energy conversion and storage schemes. Here we report the nitride-core, oxide-shell-armor structured FeCoNi oxynitride as an efficient oxygen evolution electrocatalyst with a homogeneously nitride (Fe0.70Co0.56Ni0.92N1.0O0.06) core and oxide (Fe0.4...
Stabilizing transition metals (M) in MPt alloy under acidic conditions is challenging, yet crucial to boost Pt catalysis toward oxygen reduction reaction (ORR). We synthesized ∼9 nm hard-magnet core/shell L10-CoPt/Pt nanoparticles with 2–3 atomic layers of strained Pt shell for ORR. At 60°C in acid, the hard-magnet L10-CoPt better stabilizes Co (5%...

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...
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....
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...
Chinese is an imperial language that has always loaned more than it borrowed. In the Max Planck Institute’s World Loanword Database, Mandarin Chinese has the lowest percentage of borrowings of all 41 languages studied, only 2 percent. (English, with one of the highest, has 42 percent.) In part because of the difficulty of translating alphabet-based languages into Chinese characters, it’s common to see what are called “calques”—nonphonetic literal translations like “re gou” for “hot dog” or “zhi zhu ren” for “Spiderman.” Despite (or because of) the vast appetite among the Chinese for learning English as a foreign language, Chinese ministers have recently cracked down on loanwords. And yet Chinese people still say “baibai” and “sorry”; “e-mail” is just a lot easier than “dianzi youjian,” the official substitute.

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.”
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.”

Lanthanum-transition-metal perovskites with robust mesoprous frameworks (meso-LaMO3) 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 mesopo...
To further enhance catalytic activity and durability of nanocatalysts for oxygen reduction reaction (ORR), we synthesized a new class of 20 nm × 2 nm ternary alloy FePtM (M = Cu, Ni) nanorods (NRs) with controlled compositions. Supported on carbon support and treated with acetic acid as well as electrochemical etching, these FePtM NRs were converte...
Ling was one of the highest-profile targets (next to Zhou Yongkang and Xu Caihou) of the anti-corruption campaign following the 18th Party Congress spearheaded by Party General secretary Xi Jinping and central discipline chief Wang Qishan. He was the second sitting "national leader"-level figure to be investigated by the party's anti-graft agency, after CPPCC Vice-Chairman Su Rong. Chinese-language media have linked Ling to a mysterious political network composed of prominent politicians and businesspeople with origins in Shanxi called the Xishan Society.[16]
