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.

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...

Monodisperse cobalt (Co) nanoparticles (NPs) were synthesized and stabilized against oxidation via reductive annealing at 600C. The stable Co NPs are active for catalyzing the oxygen evolution reaction (OER) in 0.1 M KOH, producing a current density of 10 mA/cm2 at an overpotential of 0.39 V (1.62 V vs. RHE, no iR-correction). Their catalysis is s...

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.
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.”

Several weeks prior to the announcement of the investigation, Ling continued to make appearances on state television in his positions of CPPCC Vice Chairman and United Front chief. On December 15 Ling had penned an article on the Communist theory publication Qiushi brimming with praise for the signature political philosophies of Xi Jinping such as the "Chinese Dream". This was seen by observers as a 'last-ditch' declaration of fealty to the new Chinese leader with whom Ling was thought to have lost favour.[11]
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...

On September 1, 2012, prior to the transfer of power between Hu Jintao and Xi Jinping at the pivotal 18th Party Congress, Ling was abruptly transferred from his position as General Office chief to become head of the United Front Work Department, an organ considered to be of less importance. This was seen as a demotion for Ling. At the 18th Party Congress held in the fall of 2012, Ling did not gain a seat on the Politburo as expected, nor did he retain his position as Secretary of the Secretariat; this signalled that Ling was excluded from all the major power organs of the party.[11] In March 2013, Ling was elected as one of the Vice-Chairmen of the Chinese People's Political Consultative Conference (CPPCC), barely holding onto his status as a "national leader". In addition, of the 23 candidates standing for confirmation for the CPPCC Vice-Chairmanship, Ling received, by far, the fewest votes in favour. A total of 90 CPPCC delegates voted against Ling, while 22 delegates abstained.[14]
Tailoring terminated edge of hexagonal boron nitride (h-BN) for enhancing catalysis has turned to be an imperative for the rational design of a highly active aerobic catalyst. Herein, a tailoring N-terminated porous BN (P-BN) strategy is reported with a zinc (Zn) salt as a dual-functional template. The Zn salt acts as both an in situ template and a...

Finally, at 15, Wang’s grandfather allowed him to start his suona training. In addition to practicing on the instrument, every day, he was to blow through a hollow reed into a basin of water to improve his breathing technique. At first, he couldn’t even make bubbles. After a year of practicing for hours each day, his grandfather gave him his first performance opportunity — but stage fright got the best of him.
On February 13, 2004, Yuntai Mountain as the fifth in the world, the third in the country China, was named the world's first World Geopark by UNESCO and caused attention at home and abroad. Meanwhile, Yuntaishan is also a national scenic spot, National Civilized Scenic Area, the first national AAAAA-level scenic spot, national natural heritage, national forest parks, national macaque nature reserve. Yuntain Mountain also has Asia's highest head drop waterfall.
Taming interfacial electronic effects on Pt nanoparticles modulated by their concomitants has emerged as an intriguing approach to optimize Pt catalytic performance. Here, we report Pt nanoparticles assembled on vacancy-abundant hexagonal boron nitride nanosheets and their use as a model catalyst to embrace an interfacial electronic effect on Pt in...
