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...
Lanthanum-transition-metal perovskites with robust meso-scale porous frameworks (meso-LaMO3) are synthesized through the 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 mesoporous complex oxides of various compositions.
From August 1983, Ling studied at the Communist Youth League Academy (later China Youth University of Political Studies), majoring in political education. In July 1985, Ling worked in the political theory section of the propaganda department of the Communist Youth League. At that time, Hu Jintao was the First Secretary (i.e., leader), of the Youth League, though it is not clear whether there was direct contact between Ling and Hu. From June 1988, Ling served in various posts in CYL, mostly as part of the CYL Secretariat and the CYL General Office. He also served as editor-in-chief of Chinese Communist Youth League, the primary theory publication of the CYL, and between 1994 and 1995, and the CYL's chief of propaganda.
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...
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...
Controlling the physical and chemical properties of alloy nanoparticles (NPs) is an important approach to optimize NP catalysis. Unlike other tuning knobs, such as size, shape and composition, crystal structure has received limited attention and not been well understood for its role in catalysis. This deficiency is mainly due to the difficulty in s...

Yet some young villagers share the government’s objections to suona funeral performances. To 27-year-old Dong Chengcheng, the funeral reforms are a positive step toward easing the burden on younger generations. “Although the price for booking a suona band is not such a big deal, it still costs money,” he explains. With each funeral typically requiring three days of ceremonies and banquets, the expenses add up — especially as family planning policies have left today’s young people with fewer siblings to share the costs.
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...

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.


Jiaozuo (Chinese: 焦作; pinyin: Jiāozuò [tɕjáu.tswô]; postal: Tsiaotso) is a prefecture-level city in northern Henan province, China. Sitting on the northern bank of the Yellow River, it borders the provincial capital of Zhengzhou to the south, Xinxiang to the east, Jiyuan to the west, Luoyang to the southwest, and the province of Shanxi to the north.Jiaozuo is one of the core cities of the Central Plains urban agglomeration and a regional central city in the Jin-Yu border area.link
Heterogeneous catalysis with core-shell structures has been a large area of focus for many years. This paper reviews the most recent work and research in coreshell catalysts utilizing noble metals, specifically gold, as the core within a metal oxide shell. The advantage of the core-shell structure lies in its capacity to retain catalytic activity u...
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....
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.
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...
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...
