The stabilization of surfactant-assisted synthesized colloidal noble metal nanoparticles (NPs, such as Au NPs) on solids is a promising strategy for preparing supported nanocatalysts for heterogeneous catalysis because of their uniform particle sizes, controllable shapes, and tunable compositions. However, surfactant removal to obtain clean surface...
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.

THERE’S NOTHING LIKE visiting Finland to make an English-speaker appreciate the value of words borrowed from other languages. Finnish, as I learned during a trip earlier this month, is an agglutinative language, in which parts of words stay distinct instead of fusing together. This makes for very long words, like “kahdenneksikymmenenneksiyhdeksänneksi” (one way to say “29,” according to my guidebook), and considerable bewilderment for a visitor. To me, it might as well have been Klingon, only with more umlauts. Every now and then, though, a light would shine through the darkness: I’d catch something like “hot jooga” or “muffensi” or “grill maisteri,” and sigh with relief.

There are 30 level two wholly owned subsidiaries, 4 class three subsidiaries and 3 joint stock class three companies under the leadership of Jihua Group Corporation Limited, these companies are located in 21 provinces, municipalities directly under the Central Government, autonomous regions, with a assets value over 10 billion yuans. It is the production and guarantee base of military supplies for Chinese army and armed police force, the main supplier for government uniform units and professional clothes units, and the main purchase and processing base for international military munitions market. Its main business scope includes the manufacturing and sale of garments, shoes and hats, textile dyeing and printing, leather fittings, rubber products; investment and management of pharmaceutical, chemical, resource development; import and export business, technical development, technical service and management consultation.
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...

Hexagonal boron nitride nanosheets (h-BNNs) with rather high specific surface area (SSA) are important two-dimensional layer-structured materials. Here, a solvent-mediated synthesis of h-BNNs revealed a template-free lattice plane control strategy that induced high SSA nanoporous structured h-BNNs with outstanding aerobic oxidative desulfurization...
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.
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.”

The recent reforms are not the first time the suona has been subject to the twists and turns of public policy. In the early days after the Communist victory in 1949, Wang’s family band played the suona not only at weddings and funerals but also at state ceremonies for sending recruits off to military service or starting construction on reservoir projects. Suona music was the soundtrack to every important moment. But during the Great Chinese Famine, no one could afford to hire musicians, and the suona was later blacklisted as part of Cultural Revolution campaigns against Confucian heritage. It wasn’t until the reform and opening-up era in the ’80s that the suona was restored to its central role in northeastern culture.
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...
