| 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 |

| 3 | Failure analysis of pouch-type Li–O2 batteries with superior energy density显示文摘Li–O2 batteries have attracted significant interest in the past decade owing to their superior high specific energy density in contrast to conventional lithium ion batteries.An 8.7-Ah Li–O2 pouch cell with768.5 Wh kg^-1 was fabricated and characterized in this investigation and the factors that influenced the electrochemical performance of the Li–O2 pouch cell were studied.In contrast to coin/Swagelok-type Li–O2 cells,it was demonstrated that the high-loading air electrode,pulverization of the Li anode,and the large-scale inhomogeneity of the large pouch cell are the major reasons for the failure of Li–O2 batteries with Ah capacities.In addition,safety tests of large Li–O2 pouch cells were conducted for the first time,including nail penetration,crushing,and thermal stability.It was indicated that a self-limiting mechanism is a key safety feature of these batteries,even when shorted.In this study,Li–O2 batteries were investigated in a new size and capacity-scale,which may provide useful insight into the development of practical pouch-type Li–O2 batteries. | Shangqian Zhao Li Zhang Gangning Zhang Haobo Sun Juanyu Yang Shigang Lu | 2020 | Journal of Energy Chemistry2020，29，6： | 2 |
| 4 | Demand-side Management Based on Model Predictive Control in Distribution Network for Smoothing Distributed Photovoltaic Power Fluctuations显示文摘With the rapid increase of distributed photovoltaic(PV) power integrating into the distribution network(DN), the critical issues such as PV power curtailment and low equipment utilization rate have been caused by PV power fluctuations. DN has less controllable equipment to manage the PV power fluctuation. To smooth the power fluctuations and further improve the utilization of PV, the regulation ability from the demandside needs to be excavated. This study presents a continuous control method of the feeder load power in a DN based on the voltage regulation to respond to the rapid fluctuation of the PV power output. PV power fluctuations will be directly reflected in the point of common coupling(PCC), and the power fluctuation rate of PCCs is an important standard of PV curtailment.Thus, a demand-side management strategy based on model predictive control(MPC) to mitigate the PCC power fluctuation is proposed. In pre-scheduling, the intraday optimization model is established to solve the reference power of PCC. In real-time control, the pre-scheduling results and MPC are used for the rolling optimization to control the feeder load demand. Finally,the data from the field measurements in Guangzhou, China are used to verify the effectiveness of the proposed strategy in smoothing fluctuations of the distributed PV power. | Jian Xu Haobo Fu Siyang Liao Boyu Xie Deping Ke Yuanzhang Sun Xiong Li Xiaotao Peng | 2022 | Journal of Modern Power Systems and Clean Energy2022，10，5： | 1 |
| 5 | 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 |

| 7 | Foldable high-strength electrode enabled by nanosheet subunits for advanced sodium-ion batteries显示文摘Power sources with strong mechanical properties and high-energy density are highly desirable for the next-generation flexible electronics.However,the challenge arises from the current electrode structure design,which is unable to bring both satisfactory mechanical and electrochemical properties with high active materials content and mass.Herein,we reported novel flexible,highstrength,and mechanically stable TiO_(2)-based film electrodes for advanced sodium-ion batteries,achieving an ultrahigh strength(up to≈60 MPa)and commercial-level areal capacity(4.5 mAh cm^(-2)).Highly-dispersed TiO_(2) and interlaced carbon nanotube(CNT)networks are embedded in the sheet-liked cellulose to form porous,high-conductive,and high-active TiO_(2)-C nanosheets that is basic building subunits of TiO_(2)-C films,allowing the films with structural robustness and origami-level flexibility.This strategy reconciles the contradiction between mechanical properties and active material content in flexible electrodes,and the fabricated electrode with a high TiO_(2) content of>65%can be bent more than 11000 times without breaking.Meanwhile,good capacity and excellent cycle stability(0.02‰capacity-decay rate over 9000 cycles)of TiO_(2)-C film under a higher active content(75%)has well satisfied the demands of flexible energy storage devices for electrochemical performances.This TiO_(2)-C subunit assembly methodology demonstrates enormous potential in high-strength/toughness flexible electrode construction for flexible electronics. | Hanwei Wang Jinzhou Fu Chao Wang Ruiwang Zhang Yingying Li Yushan Yang Haobo Li Qingfeng Sun Huiqiao Li | 2022 | InfoMat2022，4，2： | 0 |
| 8 | Effects of topdressing ratio and frequency on the dry matter, yield, and quality of tomato and celery under a small amount of continuous subsurface drip irrigation显示文摘Compared with conventional full irrigation,the existing water-saving irrigation method achieves the purpose of water saving by actively controlling soil moisture.High-frequency irrigation can make the ideal conditions for soil water movement and root absorption of water and nutrients.This research used a plot experiment in a greenhouse and set up different fertilization amounts and frequencies during the growth stage to study the effects of small-amount and continuous subsurface drip irrigation on the dry matter,yield,and quality of tomato and celery.The results showed that the frequency of topdressing had a great influence on the dry matter accumulation of tomatoes,and the amount of topdressing had little effect on the fresh weight of the upper part of a tomato plant.The application of high-frequency fertilizer increased the dry matter accumulation in the underground part of the tomato.Under the premise given amount of total fertilization,the growth rate and yield of tomatoes were positively correlated with the amount of topdressing.The optimum fertilization frequency was 1 time during the first fruit stage,3 times for the second fruit stage,and 5 times for the third fruit stage,the yield during the fourth stage was increased with higher frequency,and the topdressing was started ahead of the fourth fruit stage when the diameter of fruit was 40 mm.The lower fertilization frequency during the early stage and higher fertilization frequency during the later stage can increase the yield of celery.The higher ratio of topdressing,the higher frequency during the early growth stage,and the lower frequency during the later stage can achieve the best quality of celery. | Lingmiao Huang Peiling Yang Haobo Cui Zhanghao Sun Shumei Ren Zhaocheng Wang | 2023 | International Journal of Agricultural and Biological Engineering2023，16，3： | 0 |
