We definitely have. Some of them started out really easy to publish in with impact factor 3 or less, then in 2-3 years became picky as hell with the score shooting to 10 or 15 or so. I was part of this; I published a review with ease in 2017 or so. Wrote up a part 2 (usually, Part 2s get favorable consideration for publication) in 2020 and had to jump through so many loops the second time I could get job security death threats from circus animals.China should just start their own international scientific jounals.
If by "international", you mean high impact factor, China has already got quite some.China should just start their own international scientific jounals.
One step closer to China's goal of creating an artificial Charles LeClercThe world's first magnetic resonance platform can record and analyze the MRI and full-brain scalp electroencephalogram (EEG) in real time simultaneously.
Russia and India are participants in the Wassenaar Arrangement.
second in my series of how China broke through western tech export control is on carbon fiber and other advanced fiber.
they really destroyed wassenaar arrangement here.
that modulus number seems unreal. Even 529MPa would be very high by carbon fiber standard. 5190 MPa tensile strength would be more like a T700S level. Seems pretty crazy for a first effort here.Progress by Zhejiang university in making high performance graphene-based carbon fibre in room temperature.
经过近十五年的持续思考和探索,浙江大学高分子系高超教授团队最新工作提出“分域剪切多流场”方法,在氧化石墨烯凝胶纤维中实现微纤亚单元的液晶织构,当纤维凝固干燥时,氧化石墨烯分子在每个微纤单元内限域折叠。区别于传统氧化石墨烯分子在纤维结构中的无序折叠和堆积,微纤限域具有折叠细晶特点,大幅减少并减小了石墨烯间的微孔缺陷,形态由扁平粗孔变为针状细孔。在25℃室温催化还原下,限域折叠的石墨烯纤维表现出优异的拉伸强度(5.19GPa)和模量(529GPa),导热率、导电率分别达到232W/mK和120S/cm,同时具有92%的碳含量,实现了室温制备高性能石墨烯基碳纤维。
