Fully-ordered face-centered tetragonal (fct) FePt nanoparticles (NPs) are synthesized by thermal annealing of the MgO-coated dumbbell-like FePt-Fe3O4 NPs followed by acid washing to remove MgO. These fct-FePt NPs show strong ferromagnetism with room temperature coercivity reaching 33 kOe. They serve as a robust electrocatalyst for the oxygen reduct...

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.
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
