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. 

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.
Stabilizing transition metals (M) in MPt alloy under acidic conditions is challenging, yet crucial to boost Pt catalysis toward oxygen reduction reaction (ORR). We synthesized ∼9 nm hard-magnet core/shell L10-CoPt/Pt nanoparticles with 2–3 atomic layers of strained Pt shell for ORR. At 60°C in acid, the hard-magnet L10-CoPt better stabilizes Co (5%...
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.
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...
Jiaozuo is noted for its blast furnaces and machine construction industries. The total GDP of the city in 2017 was 234.28 billion yuan, an increase of 7.4% over the previous year. Among them, the added value of the primary industry was 13.733 billion yuan, up 4.6%; the added value of the secondary industry was 13.841 billion yuan, up 6.7%; the added value of the tertiary industry was 81.143 billion yuan, up 9.1%. The per capita GDP reached 65,936 yuan. The three industrial structures changed from 6.4:59.3:34.3 of 2016 to 5.9:59.5:34.6.link
Jihua Group Corporation Limited was founded on June 26, 2009 after having approved by State-owned Assets Supervision and Administration Commission of the State Council, and the capital was contributed by Xinxing Cathay International Group Co., Ltd. and Xinxing Real Estate (Investment) Development Co., Ltd.  On August 16, 2010, the Jihua Group (code: 601718) had successfully listed its Class A shares in Shanghai Stock Exchange. 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.
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...
EUdict (European dictionary) is a collection of online dictionaries for the languages spoken mostly in Europe. These dictionaries are the result of the work of many authors who worked very hard and finally offered their product free of charge on the internet thus making it easier to all of us to communicate with each other. Some of the dictionaries have only a few thousand words, others have more than 320,000. Some of the words may be incorrectly translated or mistyped.
My name is Tomislav Kuzmic, I live in Croatia and this site is my personal project. I am responsible for the concept, design, programming and development. I do this in my spare time. To contact me for any reason please send me an email to tkuzmic at gmail dot com. Let me take this chance to thank all who contributed to the making of these dictionaries and improving the site's quality:
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...
Monodisperse 5 nm AuMn nanoparticles were synthesized by hydride reduction of manganese acetylacetonate in the presence of Au nanoparticles. The alloy was formed through fast Mn diffusion into the Au structure. The AuMn nanoparticles were converted to Au-MnO composite particles through air annealing at 170 °C. These Au-MnO particles, especially the...
Monodisperse cobalt (Co) nanoparticles (NPs) were synthesized and stabilized against oxidation via reductive annealing at 600C. The stable Co NPs are active for catalyzing the oxygen evolution reaction (OER) in 0.1 M KOH, producing a current density of 10 mA/cm2 at an overpotential of 0.39 V (1.62 V vs. RHE, no iR-correction). Their catalysis is s...
