CO oxidation is an important reaction both experimentally and industrially, and its performance is usually dominated by the surface charge state. For example, CO oxidation on platinum (Pt) surface requires a proper charge state for the balance of adsorption and activation of CO and O2. Here, we present a “Mott−Schottky modulated catalysis” on Pt na...


Ling rose to become the Director of the General Office, an organ that handles day-to-day logistics and bureaucratic functions of the Communist Party, in 2007, when Hu was the party's General Secretary (i.e., paramount leader). He was initially seen as a promising candidate for promotion to the top leadership at the 18th Party Congress in 2012. However, his political fortunes abruptly took a turn when his 23-year-old son was killed while driving a Ferrari in 2012, an event that caused embarrassment for the party elite. Ling was then politically sidelined.
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.”
A facile approach to bimetallic phosphides, Co-Fe-P, via high-temperature (300 °C) reaction between Co-Fe-O nanoparticles and trioctylphosphine is presented. The growth of Co-Fe-P from the Co-Fe-O is anisotropic. As a result, Co-Fe-P nanorods (from the polyhedral Co-Fe-O nanoparticles) and sea-urchin-like Co-Fe-P (from the cubic Co-Fe-O nanoparticl...
The controlled exfoliation of hexagonal boron nitride (h-BN) into single- or few-layered nanosheets remains a grand challenge and becomes the bottleneck to essential studies and applications of h-BN. Here, we present an efficient strategy for the scalable synthesis of few-layered h-BN nanosheets (BNNS) using a novel gas exfoliation of bulk h-BN in...

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...
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.
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".
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...
Monodisperse core/shell FeNiPt/FePt nanowires (4.5 × 20-50 nm) are synthesized by seed-mediated growth of FePt over the pre-made 2.5 nm wide FeNiPt nanowires. The surface profile of the FeNiPt/FePt nanowires is tailored by acid and thermal treatment. The FeNiPt/Pt-skin nanowires show higher activities than the FeNiPt/Pt-skeleton nanowires. © 2015 W...
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...
