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...

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.
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.
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...
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.
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...
