| 1 | BL02U1:the relocated macromolecular crystallography beamline at the Shanghai Synchrotron Radiation Facility显示文摘Macromolecular crystallography beamline BL17U1 at the Shanghai Synchrotron Radiation Facility has been relocated,upgraded,and given a new ID(BL02U1).It now delivers X-rays in the energy range of 6–16 keV,with a focused beam of 11.6μm×4.8μm and photon flux greater than 1012 phs/s.The high credibility and stability of the beam and good timing synchronization of the equipment significantly improve the experimental efficiency.Since June 2021,when it officially opened to users,over 4200 h of beamtime have been provided to over 200 research groups to collect data at the beamline.Its good performance and stable operation have led to the resolution of several structures based on data collected at the beamline. | Ke Liu Huan Zhou Qin Xu Hua‑Ting Kong Kun‑Hao Zhang Wei‑Wei Wang Min‑Jun Li Zhi‑Jun Wang Qiang‑Yan Pan Xing‑Ya Wang Feng Yu Qi‑Sheng Wang | 2023 | Nuclear Science and Techniques2023，34，12： | 0 |
| 2 | The biosafety level-2 macromolecular crystallography beamline(BL10U2)at the Shanghai Synchrotron Radiation Facility显示文摘BL10U2 is an undulator-based macromolecular crystallography(MX)beamline located at the 3.5-GeV Shanghai Synchrotron Radiation Facility.BL10U2 is specifically designed for conducting routine and biosafety level-2(BSL-2)MX experiments utilizing high-flux tunable X-rays with energies from 7 to 18 keV,providing a beam spot size of 20μm(horizontal)×10μm(vertical)at the sample point.Certification by the Shanghai Pudong Municipal Health Commission confirmed the capability to perform BSL-2 MX experiments.The beamline is currently equipped with an Eiger X 16 M detector and two newly developed in-house high-precision diffractometers that can be switched to perform conventional or in situ crystal diffraction experiments.An automatic sample changer developed in-house allows fast sample exchange in less than 30 s,supporting high-throughput MX experimentation and rapid crystal screening.Data collection from both the diffractometer and detector was controlled by an in-house developed data collection software(Finback)with a user-friendly interface for convenient operation.This study presents a comprehensive overview of the facilities,experimental methods,and performance characteristics of the BL10U2 beamline. | Qin Xu Hua‑Ting Kong Ke Liu Huan Zhou Kun‑Hao Zhang Wei‑Wei Wang Min‑Jun Li Qiang‑Yan Pan Xing‑Ya Wang Yu‑Zhu Wang Feng Yu Xing‑Yu Gao Qi‑Sheng Wang | 2023 | Nuclear Science and Techniques2023，34，12： | 0 |
| 3 | Lithium-Ion Charged Polymer Channels Flattening Lithium Metal Anode显示文摘The concentration difference in the near-surface region of lithium metal is the main cause of lithium dendrite growth.Resolving this issue will be key to achieving high-performance lithium metal batteries(LMBs).Herein,we construct a lithium nitrate(LiNO_(3))-implanted electroactiveβphase polyvinylidene fluoride-co-hexafluoropropylene(PVDF-HFP)crystalline polymorph layer(PHL).The electronegatively charged polymer chains attain lithium ions on the surface to form lithium-ion charged channels.These channels act as reservoirs to sustainably release Li ions to recompense the ionic flux of electrolytes,decreasing the growth of lithium dendrites.The stretched molecular channels can also accelerate the transport of Li ions.The combined effects enable a high Coulombic efficiency of 97.0%for 250 cycles in lithium(Li)||copper(Cu)cell and a stable symmetric plating/stripping behavior over 2000 h at 3 mA cm^(-2)with ultrahigh Li utilization of 50%.Furthermore,the full cell coupled with PHL-Cu@Li anode and Li Fe PO_(4) cathode exhibits long-term cycle stability with high-capacity retention of 95.9%after 900 cycles.Impressively,the full cell paired with LiNi_(0.87)Co_(0.1)Mn_(0.03)O_(2)maintains a discharge capacity of 170.0 mAh g^(-1)with a capacity retention of 84.3%after 100 cycles even under harsh condition of ultralow N/P ratio of 0.83.This facile strategy will widen the potential application of LiNO_(3)in ester-based electrolyte for practical high-voltage LMBs. | Haofan Duan Yu You Gang Wang Xiangze Ou Jin Wen Qiao Huang Pengbo Lyu Yaru Liang Qingyu Li Jianyu Huang Yun‑Xiao Wang Hua‑Kun Liu Shi Xue Dou Wei‑Hong Lai | 2024 | Nano-Micro Letters2024，16，4： | 0 |
