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...
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.
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...
When languages are full of borrowed words, it’s often not by choice. Romany has many loans because of a history of extreme marginalization. Japan has a long tradition of cultural borrowing; it was also occupied for years after World War II. Vietnam, following centuries of successive occupations, has a high rate of Chinese and French loans presaging more recent English ones like “canguru,” according to the Max Planck research. Other languages are more deliberately open: According to research by Anne-Line Graedler, an English professor at Norway’s Hedmark University College, the Danes are the most welcoming Scandinavian country to loans.
To further enhance catalytic activity and durability of nanocatalysts for oxygen reduction reaction (ORR), we synthesized a new class of 20 nm × 2 nm ternary alloy FePtM (M = Cu, Ni) nanorods (NRs) with controlled compositions. Supported on carbon support and treated with acetic acid as well as electrochemical etching, these FePtM NRs were converte...
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.
Highly active, low-cost, and durable electrocatalysts for the water oxidation reaction are pivotal in energy conversion and storage schemes. Here we report the nitride-core, oxide-shell-armor structured FeCoNi oxynitride as an efficient oxygen evolution electrocatalyst with a homogeneously nitride (Fe0.70Co0.56Ni0.92N1.0O0.06) core and oxide (Fe0.4...
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".
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.

Taming interfacial electronic effects on Pt nanoparticles modulated by their concomitants has emerged as an intriguing approach to optimize Pt catalytic performance. Here, we report Pt nanoparticles assembled on vacancy-abundant hexagonal boron nitride nanosheets and their use as a model catalyst to embrace an interfacial electronic effect on Pt in...

Li Bingxiang, a suona fan and former Party secretary of a village in Pingyi County, also believes the instrument has fallen victim to the wide net cast to prevent ostentatious funerals. “The main extravagant expenses are the banquet, coffin, and labor costs for a three-day ceremony,” Li says. “There should be a compromise that reaches the government’s goals but also preserves traditions.”

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.

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....
