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...
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...

Linguistic loans can appear in a number of forms: Some float on the surface of a language, while others are more integrated. Because English and Japanese have very different sound systems, for instance, Japan often adapts words in ways that make them nearly unrecognizable to English-speakers. Über-Japanese media franchise Pokémon actually takes its name from English (“pocket monster”). Japan’s “puroresu” is another abbreviated compound, from “professional wrestling”; similarly, the extra syllables required to pronounce English consonants have given rise to “purasuchikku” (“plastic”) and “furai” (“fry”). Then there are loans where a word stays intact but the meaning shifts. A “smoking” is French for a tuxedo, and a “dressman” is a German male model. Chinese people say they want to “high” when they want to have a (non-drug-related) good time.
Jiaozuo (Chinese: 焦作; pinyin: Jiāozuò [tɕjáu.tswô]; postal: Tsiaotso) is a prefecture-level city in northern Henan province, China. Sitting on the northern bank of the Yellow River, it borders the provincial capital of Zhengzhou to the south, Xinxiang to the east, Jiyuan to the west, Luoyang to the southwest, and the province of Shanxi to the north.Jiaozuo is one of the core cities of the Central Plains urban agglomeration and a regional central city in the Jin-Yu border area.link
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.”
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%...

To performers, the suona has unfairly taken the blame for other, more vulgar, funeral practices. Wang believes the reforms have only crushed suona music and firecrackers because noise easily draws officials’ attention. Earlier this year, the Pingyi County government announced it would confiscate musical instruments played at funerals. When Wang and other suona masters performed at the funeral of an esteemed elder in June, village officials barged in and caused a commotion. The suona was small enough to be quickly hidden, but bigger instruments were snatched away.
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.

But that imbalance can build resentment. In France, the secretary of the Academie Française called last December for a “reconquest of the French language” from loanwords; in China, government-friendly papers printed screeds this spring against “Wi-Fi,” “VIP,” and “e-mail.” Even as many governments work to protect languages from the spread of English, however, speakers in those countries go blithely off to “hot jooga,” meaning that official policy and the daily reality of English may be very different things.
