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...
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...
Linguistic loans can appear in a number of forms: Some float on the surface of a language, while others are more integrated. Because English and Japanese have very different sound systems, for instance, Japan often adapts words in ways that make them nearly unrecognizable to English-speakers. Über-Japanese media franchise Pokémon actually takes its name from English (“pocket monster”). Japan’s “puroresu” is another abbreviated compound, from “professional wrestling”; similarly, the extra syllables required to pronounce English consonants have given rise to “purasuchikku” (“plastic”) and “furai” (“fry”). Then there are loans where a word stays intact but the meaning shifts. A “smoking” is French for a tuxedo, and a “dressman” is a German male model. Chinese people say they want to “high” when they want to have a (non-drug-related) good time.
Lanthanum-transition-metal perovskites with robust meso-scale porous frameworks (meso-LaMO 3) are synthesized through 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.
High-quality graphene flakes have long been desirable for numerous applications including energy storage, printable electronics, and catalysis. In this contribution, we report a green, efficient, facile gas-driven exfoliation process for the preparation of high-quality graphene in large scale. The gas exfoliation process was realized by the interpl...
Elaborate and sometimes outrageous funeral services featuring everything from strippers to the burning of ghost money drew the attention of international media and local authorities in 2015, but now, even the suona has been caught in the crossfire. In November 2016, 21 professors from prominent institutions like Peking University signed a public appeal for the protection of village funeral traditions, saying that the government reforms ought to allow folk customs in keeping with cultural revival and only forbid extravagant vices such as stripping.
The sentencing revealed many details which were previously unknown. The conviction stated that Ling had sought to use his influence to advance the interests of senior regional officials Li Chuncheng, Pan Yiyang, and Bai Enpei; all three had fallen under the axe of the anti-corruption campaign though their links to Ling were unclear hitherto the conviction. It also stated that his wife, Gu Liping, and his son, Ling Gu, had taken some bribes on behalf of the Ling family. Ling Gu was said to have solicited bribes worth some 6.5 million yuan (~$1 million) from Wei Xin, a senior executive of Founder Group. Ling and his wife, Gu Liping, additionally were said to have received some 15 million yuan (~$2.3 million) from Guangsha Group, in exchange for political favours from Ling. Following his departure from the General Office, it was said that Ling gained access to privileged state secrets through his former subordinate Huo Ke, who was also indicted and tried.
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. "Linghu" is a very rare surname, eventually most members of the Ling family shortened the "Linghu" to "Ling".
Though it has banned the suona from funerals, the local government has also paradoxically launched several initiatives to preserve the suona tradition. Since 2014, it has funded research and documentation of suona music, as well as an intangible cultural heritage protection plan that pairs around 15 masters with students. It also offers suona musicians performance opportunities. But according to Liu, the gigs are too few and too poorly compensated — some only pay 800 to 1,000 yuan ($120 to $150) for an eight-person band. He doesn’t believe that a state-sponsored imitation of the master-apprentice method will be able to sustain the tradition.
Sometimes purism peaks after a war or in a post-colonial situation. South Korea tried to de-Japanify its language after World War II; the Indian and Pakistani governments tried to separate Hindi and Urdu after their partition. A purist approach can also be a smaller language’s way of resisting outside influence. In Iceland, the Icelandic Language Institute preserves the country’s Viking-era language by cobbling together new terms from indigenous roots. Some Native American groups do the same to resist English.
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.
It’s not hard to see why governments would seek to defend their languages. But some linguists think a staunch anti-English stance may be counterproductive. Truly endangered languages tend to be encroached on mostly by their dominant geographic neighbors, says Selma Sonntag, a political scientist at Humboldt State University who studies language purist movements: “The threat isn’t from English, it’s from whatever the official language is within their area.” Linguist David Crystal, author of “English as a Global Language,” has written about how Welsh-language purism may be furthering an elitism that prevents younger speakers from adopting the tongue. And it’s worth noting that English owes much of its vitality to its long history of borrowing from French, Latin, Arabic, and pretty much any other language it met. “Loanwords...do alter [a language’s] character—but is this a bad thing?” Crystal told me. “Imagine English without French or Latin loanwords. No Shakespeare, for a start.”
Finally, at 15, Wang’s grandfather allowed him to start his suona training. In addition to practicing on the instrument, every day, he was to blow through a hollow reed into a basin of water to improve his breathing technique. At first, he couldn’t even make bubbles. After a year of practicing for hours each day, his grandfather gave him his first performance opportunity — but stage fright got the best of him.
In December 1995, after serving in CYL for over ten years, Ling was transferred to General Office of the Communist Party of China, and continued his work in political theory. Between 1994 and 1996 Ling obtained an "on-job master's degree" in commercial management at Hunan University. In June 1998, he was promoted to head of research office of the General Office (中央办公厅调研室主任). In December 1999, Ling was appointed as deputy director of General Office. Later, he also served as the deputy chief of the General Office in charge of the Central Institutional Organization Commission, and chief of staff of the Office of General Secretary Hu Jintao.
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...
