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...

NixWO2.72 nanorods (NRs) are synthesized by a one-pot reaction of Ni(acac)2 and WCl4. In the rod structure, Ni(II) intercalates in the defective perovskite-type WO2.72 and is stabilized. The NixWO2.72 NRs show the x-dependent electrocatalysis for the oxygen evolution reaction (OER) in 0.1M KOH with Ni0.78WO2.72 being the most efficient, even outper...

Using FePtAu nanoparticles (NPs) as an example, this Communication demonstrates a new structure-control strategy to tune and optimize NP catalysis. The presence of Au in FePtAu facilitates FePt structure transformation from chemically disordered face-centered cubic (fcc) structure to chemically ordered face-centered tetragonal (fct) structure, and...
Jihua Group Corporation Limited was founded on June 26, 2009 after having approved by State-owned Assets Supervision and Administration Commission of the State Council, and the capital was contributed by Xinxing Cathay International Group Co., Ltd. and Xinxing Real Estate (Investment) Development Co., Ltd.  On August 16, 2010, the Jihua Group (code: 601718) had successfully listed its Class A shares in Shanghai Stock Exchange. There are 30 level two wholly owned subsidiaries, 4 class three subsidiaries and 3 joint stock class three companies under the leadership of Jihua Group Corporation Limited, these companies are located in 21 provinces, municipalities directly under the Central Government, autonomous regions, with a assets value over 10 billion yuans. It is the production and guarantee base of military supplies for Chinese army and armed police force, the main supplier for government uniform units and professional clothes units, and the main purchase and processing base for international military munitions market. Its main business scope includes the manufacturing and sale of garments, shoes and hats, textile dyeing and printing, leather fittings, rubber products; investment and management of pharmaceutical, chemical, resource development; import and export business, technical development, technical service and management consultation.
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...
To performers, the suona has unfairly taken the blame for other, more vulgar, funeral practices. Wang believes the reforms have only crushed suona music and firecrackers because noise easily draws officials’ attention. Earlier this year, the Pingyi County government announced it would confiscate musical instruments played at funerals. When Wang and other suona masters performed at the funeral of an esteemed elder in June, village officials barged in and caused a commotion. The suona was small enough to be quickly hidden, but bigger instruments were snatched away.
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.

We report the synthesis of core/shell face-centered tetragonal (fct)-FePd/Pd nanoparticles (NPs) via reductive annealing of core/shell Pd/Fe3O4 NPs followed by temperature-controlled Fe etching in acetic acid. Among three different kinds of core/shell FePd/Pd NPs studied (FePd core at ~8 nm and Pd shell at 0.27, 0.65 or 0.8 nm), the fct-FePd/Pd-0.6...


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
