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...

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 a common experience for English speakers abroad: suddenly recognizing a familiar word in a newspaper, or on a billboard, or in a fragment of conversation. Since World War II, English has become by far the leading exporter of “loanwords,” as they’re known, including nearly universal terms like “OK,” “Internet,” and “hamburger.” The extent to which a language loans words is a measure of its prestige, said Martin Haspelmath, a linguist at the Max Planck Institute. English, clearly, is now on top.
We report a facile halide ion (Cl(-) or Br(-)) mediated synthesis of Fe nanoparticles (NPs) by thermal decomposition of Fe(CO)5. The NP structure is controlled to be either amorphous (in the absence of halide ions) or single crystalline bcc (in the presence of halide ions). Through systematic investigation on the synthetic conditions, we have confi...

Tailoring the atomic structural configuration at metal and oxide interface offers an effective route for the development of catalysts with optimized properties. Here, we report the design of a unique structural configuration of yolk-shell-like FePt-FeOx nanoparticles (NPs), that exhibits notably enhanced activity and stability towards CO oxidation...

Most languages fall somewhere in between the extremes. Many European countries went through a period of linguistic nationalism in the 19th century and continue to regulate loans today. The Language Council of Norway, for example, has created official “Norwegian” spellings for English loanwords since 1996—although some, like “pøbb” (pub), were apparently rejected by the Norwegian people. Finland, fairly open to loans, has the Kielitoimisto, the Finnish Language Office, which helps create neologisms like “pehmelö” (“smoothie”) and advises on how to adapt foreign words into Finnish. Smaller European languages like Czech, Slovenian, and Croatian (with its “džez,” or jazz, and “hardver”), have traditionally been more resistant than larger ones.

THERE’S NOTHING LIKE visiting Finland to make an English-speaker appreciate the value of words borrowed from other languages. Finnish, as I learned during a trip earlier this month, is an agglutinative language, in which parts of words stay distinct instead of fusing together. This makes for very long words, like “kahdenneksikymmenenneksiyhdeksänneksi” (one way to say “29,” according to my guidebook), and considerable bewilderment for a visitor. To me, it might as well have been Klingon, only with more umlauts. Every now and then, though, a light would shine through the darkness: I’d catch something like “hot jooga” or “muffensi” or “grill maisteri,” and sigh with relief.
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.
