| 1 | Protonation induced high-T_c phases in iron-based superconductors evidenced by NMR and magnetization measurements显示文摘Chemical substitution during growth is a well-established method to manipulate electronic states of quantum materials, and leads to rich spectra of phase diagrams in cuprate and iron-based superconductors. Here we report a novel and generic strategy to achieve nonvolatile electron doping in series of(i.e.11 and 122 structures) Fe-based superconductors by ionic liquid gating induced protonation at room temperature. Accumulation of protons in bulk compounds induces superconductivity in the parent compounds, and enhances the Tclargely in some superconducting ones. Furthermore, the existence of proton in the lattice enables the first proton nuclear magnetic resonance(NMR) study to probe directly superconductivity. Using Fe S as a model system, our NMR study reveals an emergent high-Tcphase with no coherence peak which is hard to measure by NMR with other isotopes. This novel electric-fieldinduced proton evolution opens up an avenue for manipulation of competing electronic states(e.g.Mott insulators), and may provide an innovative way for a broad perspective of NMR measurements with greatly enhanced detecting resolution. | Yi Cui Gehui Zhang Haobo Li Hai Lin Xiyu Zhu Hai-Hu Wen Guoqing Wang Jinzhao Sun Mingwei Ma Yuan Li Dongliang Gong Tao Xie Yanhong Gu Shiliang Lie Huiqian Luo Pu Yu Weiqiang Yu | 2018 | Science Bulletin2018，63，1： | 7 |
| 2 | Metal recycling from waste memory modules efficiently and environmentally friendly by low-temperature alkali melts显示文摘Recycling of waste electrical and electronic equipment has become an urgent global issue in recent years from the prospectives of resources recycling and environmental protection.In the present work,the recycling of waste memory modules(WMMs)through low-temperature alkali melts was investigated,based on the thermodynamic analysis of the nonmetallic reactions of brominated epoxy resin,glass fiber and memory chip with the molten mixed alkali.The effects of the reaction temperature and the ratio of alkali mixture on the removal rate of nonmetallic parts in WMMs were discussed under the condition of air atmosphere.The optimum process parameters were further confirmed by in-situ monitoring of the temperature during the whole reaction process.The mixtures with Cu,Fe and Ni as the main components were obtained after the treatment of WMMs in the molten alkali.These mixed metals were further separated into copper-rich and ferronickel-rich metals by physical magnetic separation.Moreover,the precious metals Au and Ag were enriched in Cu-rich alloys.This work provided an efficient and environment-friendly method for metal recycling from WMMs. | ZHU MingWei MA HaoBo HE Jie CHEN Bin ZHANG LiLi JIANG HongXiang SUN XiaoJun ZHAO JiuZhou | 2020 | Science China(Technological Sciences)2020，63，11： | 1 |
