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.
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...
For Wang, suona music runs in his blood. Yet even with four generations of suona players among his forebears, it took him years of practice to master even the basics on the notoriously difficult instrument. As a child, he spent months playing cymbals in his grandfather’s band to improve his sense of rhythm. Then, from the age of 8, he started learning the sheng mouth organ to perfect his intonation and dropped out of school to focus on music.

We report a facile halide ion (Cl(-) or Br(-)) mediated synthesis of Fe nanoparticles (NPs) by thermal decomposition of Fe(CO)5. The NP structure is controlled to be either amorphous (in the absence of halide ions) or single crystalline bcc (in the presence of halide ions). Through systematic investigation on the synthetic conditions, we have confi...
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]
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...
