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...
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....
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...
On September 19, 2007 Ling was promoted to become Director of General Office of the Communist Party of China, the nerve center of the party that was in charge of all manner of administrative activities of the party's central authorities, including communications and leaders' scheduling and agendas. He also became a Secretary of the Central Secretariat, in charge of the implementation of tasks set forth by the party's Politburo.
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.

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...
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...
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...
Henan Polytechnic University (HPU)[1], with a history of nearly 100 years, is the first mining university in Chinese history. Its former is Jiaozuo Coal Mining School which was established by the British Syndicate Co. Ltd., in 1909. It has changed its names several times in the course of development, namely, FuZhong Coal Mining University, Jiaozuo Private Institute of Technology, North-west Institute of Technology, Jiaozuo National Institute of Technology, Jiaozuo Mining Institute and Jiaozuo Institute of Technology. The University resumed its name of Henan Polytechnic University in 2004.
When England became an empire, English began borrowing less and became the prolific word lender it is today, Haspelmath told me. If we start borrowing again—the way Arabic stopped exporting words to the rest of the world once its empire crumbled and started borrowing more from French and English—we’ll know we’ve seen the apex of our cultural influence. Until then, at least we’ll be able to find a hot yoga class just about anywhere in the world.
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.
SHANDONG, East China — The unmistakable wail of the suona pierces the dusk in the village as Wang Ruiyong plays a traditional tune on the double-reed instrument. The elderly funeral attendees approve, recognizing the melody. Yet for nearly five years now, Wang and other suona masters have been recording their repertoire in the fear that the songs could soon be forgotten as their tradition increasingly comes under threat.
Despite media censorship regarding the event, news of the crash was widely circulated in China. The incident was also later reported on major international media, including the Wall Street Journal and Reuters. Online Chinese-language communities also questioned how Ling Gu could afford a car worth some $500,000 when his parents had government jobs.[6] The crash and subsequent suppression was said to have led to Ling Jihua's demotion in August 2012,[1][6] and his wife Gu Liping's removal from her job in January 2013.[13]
