| 1 | A Healable and Mechanically Enhanced Composite with Segregated Conductive Network Structure for High‑Efficient Electromagnetic Interference Shielding显示文摘It is still challenging for conductive polymer composite-based electromagnetic interference(EMI)shielding materials to achieve long-term stability while maintaining high EMI shielding effectiveness(EMI SE),especially undergoing external mechanical stimuli,such as scratches or large deformations.Herein,an electrostatic assembly strategy is adopted to design a healable and segregated carbon nanotube(CNT)/graphene oxide(GO)/polyurethane(PU)composite with excellent and reliable EMI SE,even bearing complex mechanical condition.The negatively charged CNT/GO hybrid is facilely adsorbed on the surface of positively charged PU microsphere to motivate formation of segregated conductive networks in CNT/GO/PU composite,establishing a high EMI SE of 52.7 dB at only 10 wt%CNT/GO loading.The Diels–Alder bonds in PU microsphere endow the CNT/GO/PU composite suffering three cutting/healing cycles with EMI SE retention up to 90%.Additionally,the electrostatic attraction between CNT/GO hybrid and PU microsphere helps to strong interfacial bonding in the composite,resulting in high tensile strength of 43.1 MPa and elongation at break of 626%.The healing efficiency of elongation at break achieves 95%when the composite endured three cutting/healing cycles.This work demonstrates a novel strategy for developing segregated EMI shielding composite with healable features and excellent mechanical performance and shows great potential in the durable and high precision electrical instruments. | Ting Wang Wei‑Wei Kong Wan‑Cheng Yu Jie‑Feng Gao Kun Dai Ding‑Xiang Yan Zhong‑Ming Li | 2021 | Nano-Micro Letters2021，13，11： | 4 |
| 2 | Measurement of Br(n,γ)cross sections up to stellar s-process temperatures at the CSNS Back‑n显示文摘The neutron capture cross sections(n,γ)of bromine were obtained using the time-of-flight technique at the Back-n facility of the China Spallation Neutron Source.Promptγ-rays originating from neutron-induced capture events were detected using four C_(6)D_(6) detectors.The pulse-height weighting technique and double-bunch unfolding method based on Bayesian theory were used in the data analysis.Background deductions,normalization,and corrections were carefully considered to obtain reliable measurement results.The multilevel R-matrix Bayesian code SAMMY was used to extract the resonance parameters in the resolved resonance region(RRR).The average cross sections in the unresolved resonance region(URR)were obtained from 10 to 400 keV.The experimental results were compared with data from several evaluated libraries and previous experi-ments in the RRR and URR.The TALYS code was used to describe the average cross sections in the URR.The astrophysical Maxwell average cross sections(MACSs)of ^(79,81)Br from kT=5 to 100 keV were calculated over a sufficiently wide range of neutron energies.At a thermal energy of kT=30 keV,the MACS value for ^(79)Br 682±68 mb was in good agreement with the KADoNiS v1.0 recommended value.By contrast,the value of 293±29 mb for ^(81)Br was substantially higher than that of the evaluated database and the KADoNiS v1.0 recommended value. | Gao‑Le Yang Zhen‑Dong An Wei Jiang Xian‑Kai Li Wei‑Wei Qiu Zheng‑Fa Liao Zi‑Yue Zhuang Xiao‑Ping Zhang Sheng‑Li Chen Chen‑Chen Guo Er‑Xi Xiao Xiao Fang Xin‑Xiang Li Xin‑Rong Hu Bing Jiang Jin‑Cheng Wang Jie Ren Wen Luo Zhi‑Chao Zhu Hao‑Yang Lan Zong‑Wei Cao Xu Ma Ying‑Du Liu Pu‑Sen Wang Yi Yang Ping Su Xian‑Gai Deng Wan‑Bing He Chun‑Wang Ma Yu‑Ting Wang Zhi‑Tao Dai Peng‑Qin He Ren‑Guang Tang Tao Zhou Jing Wang Han Yi Yue Zhang Yong‑Hao Chen Rui‑Rui Fan Ke‑Qing Gao Qiang Li Kang Sun Zhi‑Xin Tan Min‑Hao Gu Han‑Tao Jing Jing‑Yu Tang | 2023 | Nuclear Science and Techniques2023，34，11： | 0 |
