Silicon (Si) has been regarded as next-generation anode for high-energy lithium-ion batteries (LIBs) due to its high Li storage capacity (4200 mA h g−1). However, the mechanical degradation and resultant capacity fade critically hinder its practical application. In this regard, we demonstrate that nanocoating of Si spheres with a 3 nm titanium diox...
A facile approach to bimetallic phosphides, Co-Fe-P, via high-temperature (300 °C) reaction between Co-Fe-O nanoparticles and trioctylphosphine is presented. The growth of Co-Fe-P from the Co-Fe-O is anisotropic. As a result, Co-Fe-P nanorods (from the polyhedral Co-Fe-O nanoparticles) and sea-urchin-like Co-Fe-P (from the cubic Co-Fe-O nanoparticl...

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.


In this communication, we report a facile approach to constructing catalytic active hierarchical interfaces in 1-dimensional (1D) nanostructure, exemplified by the synthesis of TiO2-supported PtFe-FeOx nanowires (NWs). The hierarchical interface, constituting of atomic level interactions between PtFe and FeOx within each NW and the interactions bet...

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...

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.”
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.

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...

Its population was 3,700,000 at the 2016 census whom 1,301,732 live in the built-up area made of 4 urban districts (Jiefang, Shanyang, Zhongzhan and Macun) and Bo'ai County being urbanized. Jiaozuo enjoys a humid subtropical climate with continental climate influences. Winters are cool and relatively dry while summers are hot and often rainy. Average temperature ranges from 0.3 °C in January to 27.5 °C in July. Extremes exist from -22.4 °C to 43.6 °C. Precipitation averages 659 mm.
A kind of Ti–Fe–Ni–C compound powder was prepared by a novel precursor pyrolysis process using ferro-titanium, carbonyl nickel powder and sucrose as raw materials. The powder had a very compact structure and was uniform in particle size. The TiC–Fe36Ni composite coatings were simultaneously in-situ synthesized by Reactive Detonation-gun Spraying (RDS) using these Ti-Fe-Ni-C compound powders. The coatings presented typical morphology of thermal spraying coatings with two different areas: one was the area of TiC distribution where the round fine TiC particles (from 300nm to 1μm) were dispersed in the Fe36Ni alloy matrix; the other was the area of TiC accumulation (from 2 to 4μm). The surface hardness of the composite coating reached about 94 ± 2(HR15N).
A simple, solvent-free, solid-state self-assembly strategy for the synthesis of alkaline-metal-oxide-doped mesoporous carbons (MCs) with tunable mesopores (~5-9 nm), high surface-areas (up to 571 m2/g) and large pore volumes (up to 0.65 cm3/g) is developed via the mechanochemical assembly between polyphenol-Ca2+/Mg2+ composites and F127 copolymers....
