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...
In the latter half of 2014, members of the Ling family were successively detained by the authorities (see "Family" section below). Moreover, an unprecedented number of high-ranking officials in Ling's native Shanxi province were investigated for corruption and removed from office. Rumours circulated about Ling's own fate. Ling was officially placed under investigation by the Central Commission for Discipline Inspection (party's anti-graft agency) on December 22, 2014, and dismissed from his position as United Front Work Department head about a week later. The CPPCC then removed him from the office of Vice-Chairman in February 2015, in addition to stripping him of his ordinary CPPCC delegate status.
Controlling nanoparticle (NP) surface strain, i.e. compression (or stretch) of surface atoms, is an important approach to tune NP surface chemistry and to optimize NP catalysis for chemical reactions. Here we show that surface Pt strain in the core/shell FePt/Pt NPs with Pt in 3 atomic layers can be rationally tuned via structure transition of FePt...
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.
As a teenager in the 1980s, Wang would play several gigs a day with his grandfather’s band. Everywhere they performed, they were served tea and tobacco and treated as honored guests. But after the arrival of the new millennium, the popularity of suona music declined. The market for musicians shrank as newlyweds turned to new trends: Western rock bands, pop singers, folk operas. The suona became passé, even maudlin. “Once the suona sounded, people would think someone must have passed away,” Wang explains.
The most successful band in Pingyi County is headed by 29-year-old Liu Ji. In jeans and a tight white T-shirt, with a gleaming stud in his ear, Liu looks the perfect antithesis of Wang, the traditionalist in gray trousers and a loose white shirt. Yet Liu, too, learned to play the suona with a reed and a water basin, he says, practicing through hot summer days until the sweat from his feet soaked prints into the ground. He, too, inherited his band from his family, but he added young acrobats, dancers, singers, and Western instruments.
Jiaozuo is noted for its blast furnaces and machine construction industries. The total GDP of the city in 2017 was 234.28 billion yuan, an increase of 7.4% over the previous year. Among them, the added value of the primary industry was 13.733 billion yuan, up 4.6%; the added value of the secondary industry was 13.841 billion yuan, up 6.7%; the added value of the tertiary industry was 81.143 billion yuan, up 9.1%. The per capita GDP reached 65,936 yuan. The three industrial structures changed from 6.4:59.3:34.3 of 2016 to 5.9:59.5:34.6.link
SHANDONG, East China — The unmistakable wail of the suona pierces the dusk in the village as Wang Ruiyong plays a traditional tune on the double-reed instrument. The elderly funeral attendees approve, recognizing the melody. Yet for nearly five years now, Wang and other suona masters have been recording their repertoire in the fear that the songs could soon be forgotten as their tradition increasingly comes under threat.
Monodisperse 5 nm AuMn nanoparticles were synthesized by hydride reduction of manganese acetylacetonate in the presence of Au nanoparticles. The alloy was formed through fast Mn diffusion into the Au structure. The AuMn nanoparticles were converted to Au-MnO composite particles through air annealing at 170 °C. These Au-MnO particles, especially the...
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.”
