Monodisperse core/shell FeNiPt/FePt nanowires (4.5 × 20-50 nm) are synthesized by seed-mediated growth of FePt over the pre-made 2.5 nm wide FeNiPt nanowires. The surface profile of the FeNiPt/FePt nanowires is tailored by acid and thermal treatment. The FeNiPt/Pt-skin nanowires show higher activities than the FeNiPt/Pt-skeleton nanowires. © 2015 W...
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.
“It’s quite hard for us to find jobs,” Wang says. “We’re not young, and we don’t have other skills.” When he first started doing short-term construction work earlier this year, he didn’t even know how to mix concrete, but other workers were friendly and helped teach him the basics. He doesn’t mind the labor, though it leaves him sore. He feels his cheeks are stiff after days away from the suona — a reminder that he was once a master musician.
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.
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.
When England became an empire, English began borrowing less and became the prolific word lender it is today, Haspelmath told me. If we start borrowing again—the way Arabic stopped exporting words to the rest of the world once its empire crumbled and started borrowing more from French and English—we’ll know we’ve seen the apex of our cultural influence. Until then, at least we’ll be able to find a hot yoga class just about anywhere in the world.
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...
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.”
The importance of porous carbon as the support material is well recognized in the catalysis community, and it would be even more attractive if several characteristics are considered, such as the stability in acidic and basic media or the ease of noble metal recovery through complete burn off. Because it is still difficult to obtain constant propert...
