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... 

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...

On July 20, 2015, Ling was expelled from the Communist Party of China,[17] and was arrested to face criminal proceedings.[18] Ling's case received significant media attention, since he was the most prominent political figure expelled from the party since criminal proceedings were initiated against former Politburo Standing Committee member Zhou Yongkang. In the party's disciplinary dossier against Ling, he was accused of "violating political discipline, violating political rules, violating organizational discipline, and violating confidentiality discipline." He was further accused of taking in large bribes, aiding in the business interests of his wife, sexual misconduct with "numerous women", and illegally obtaining party and state secrets.[19]


Lanthanum-transition-metal perovskites with robust mesoprous frameworks (meso-LaMO3) 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 mesopo...
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...

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.”
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...

Born Linghu Jihua, Ling was the third son to Linghu Ye (令狐野), a party official, in Pinglu County, Shanxi Province. He and all four of his siblings received names related to the Communist Party's policies. His own name, Jihua, means "planning". In December 1973, as with many other young Chinese, he was sent to work in the countryside as part of the Down to the Countryside Movement. Ling worked in a printing factory.[4] "Linghu" is a very rare surname, eventually most members of the Ling family shortened the "Linghu" to "Ling".
Jiaozuo is noted for its blast furnaces and machine construction industries. The total GDP of the city in 2017 was 234.28 billion yuan, an increase of 7.4% over the previous year. Among them, the added value of the primary industry was 13.733 billion yuan, up 4.6%; the added value of the secondary industry was 13.841 billion yuan, up 6.7%; the added value of the tertiary industry was 81.143 billion yuan, up 9.1%. The per capita GDP reached 65,936 yuan. The three industrial structures changed from 6.4:59.3:34.3 of 2016 to 5.9:59.5:34.6.link
