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...
“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.
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...
High-quality graphene flakes have long been desirable for numerous applications including energy storage, printable electronics, and catalysis. In this contribution, we report a green, efficient, facile gas-driven exfoliation process for the preparation of high-quality graphene in large scale. The gas exfoliation process was realized by the interpl...
Throughout Hu Jintao's leadership, Ling accompanied Hu on trips abroad and was often seen with Hu on inspection visits around the country. As one of Hu Jintao's closest associates and most trusted advisors, in addition to being of an appropriate level of seniority, Ling seemed long destined for higher office. Ling's political fortunes, however, took an abrupt turn in 2012. On March 18, Ling's only son, then 23-Year old Ling Gu, was involved and killed in a car crash on Beijing's 4th Ring Road while driving a black[1] Ferrari 458 Spider accompanied by two women, reportedly of minority ethnic background, who survived.[5] Ling Gu was said to have been found naked, and the women were described as either naked or otherwise "scantily clad," which seemed to suggest sexual activity while driving.[6] While this account was later disputed, the widely discussed "Ferrari crash" was juicy tabloid fodder and exacerbated public cynicism over the debauchery and conspicuous consumption often associated with children of the Communist ruling elite.[7]
Hexagonal boron nitride nanosheets (h-BNNs) with rather high specific surface area (SSA) are important two-dimensional layer-structured materials. Here, a solvent-mediated synthesis of h-BNNs revealed a template-free lattice plane control strategy that induced high SSA nanoporous structured h-BNNs with outstanding aerobic oxidative desulfurization...

To further enhance catalytic activity and durability of nanocatalysts for oxygen reduction reaction (ORR), we synthesized a new class of 20 nm × 2 nm ternary alloy FePtM (M = Cu, Ni) nanorods (NRs) with controlled compositions. Supported on carbon support and treated with acetic acid as well as electrochemical etching, these FePtM NRs were converte...


Perhaps the best way to enable dictionary search is through integration into the search field of your browser. To add EUdict alongside Google, Yahoo!, Amazon and other search engines in Mozilla Firefox or Internet Explorer, simply click on link after the title Browser integration, select appropriate language pair and confirm your decision. And you're ready to go; select EUdict from the drop-down list in search field (Firefox) or address bar (IE), input a word and press Enter. In Chrome, first click on a language pair and change the search keyword in the field 'Keyword' to a keyword (eg: 'eudict'). Afterwards, you simply type the chosen keyword in the address bar to start the search in the chosen dictionary.

EUdict (European dictionary) is a collection of online dictionaries for the languages spoken mostly in Europe. These dictionaries are the result of the work of many authors who worked very hard and finally offered their product free of charge on the internet thus making it easier to all of us to communicate with each other. Some of the dictionaries have only a few thousand words, others have more than 320,000. Some of the words may be incorrectly translated or mistyped.

Fully-ordered face-centered tetragonal (fct) FePt nanoparticles (NPs) are synthesized by thermal annealing of the MgO-coated dumbbell-like FePt-Fe3O4 NPs followed by acid washing to remove MgO. These fct-FePt NPs show strong ferromagnetism with room temperature coercivity reaching 33 kOe. They serve as a robust electrocatalyst for the oxygen reduct...

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]
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.

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...

The recent reforms are not the first time the suona has been subject to the twists and turns of public policy. In the early days after the Communist victory in 1949, Wang’s family band played the suona not only at weddings and funerals but also at state ceremonies for sending recruits off to military service or starting construction on reservoir projects. Suona music was the soundtrack to every important moment. But during the Great Chinese Famine, no one could afford to hire musicians, and the suona was later blacklisted as part of Cultural Revolution campaigns against Confucian heritage. It wasn’t until the reform and opening-up era in the ’80s that the suona was restored to its central role in northeastern culture.

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...
