It has long been speculated that magnetars are the engine powering repeating bursts from FRB sources4-13, but no convincing evidence has been collected so far14. Recently, the Galactic magnetar SRG 1935+2154 entered an active phase by emitting intense soft íray bursts15. One FRB-like event with two peaks (FRB 200428) and a luminosity slightly lower than the faintest extragalactic FRBs was detected from the source, in association with a soft íray/hard-X-ray flare18-21. Here we report an eight-hour targeted radio observational campaign comprising four sessions and assisted by multi-wavelength (optical and hard-X-ray) data. During the third session, 29 soft-íray repeater (SGR) bursts were detected in íray energies. Throughout the observing period, we detected no single dispersed pulsed emission coincident with the arrivals of SGR bursts, but unfortunately we were not observing when the FRB was detected. The non-detection places a fluence upper limit that is eight orders of magnitude lower than the fluence of FRB 200428. Our results suggest that FRB-SGR burst associations are rare. FRBs may be highly relativistic and geometrically beamed, or FRB-like events associated with SGR bursts may have narrow spectra and characteristic frequencies outside the observed band. It is also possible that the physical conditions required to achieve coherent radiation in SGR bursts are difficult to satisfy, and that only under extreme conditions could an FRB be associated with an SGR burst.   Preparation of Multicolor Photoluminescent Carbon Dots by Tuning Surface States 期刊论文  OAI收割 NANOMATERIALS, 2019, 卷号: 9, 期号: 4 作者:  Jiang, Kai;  Feng, Xiangyu;  Gao, Xiaolu;  Wang, Yuhui;  Cai, Congzhong   |  收藏  |  浏览/下载：127/0  |  提交时间：2019/12/18 GRAPHENE QUANTUM DOTS  FULL-COLOR EMISSION  LONG-WAVELENGTH  FLUORESCENCE  CHALLENGES  RED  LUMINESCENCE  MECHANISM  NANODOTS  GREEN   Wavelength Drift Correction Method Based on Energy Redistribution 期刊论文  OAI收割 CHEMICAL JOURNAL OF CHINESE UNIVERSITIES-CHINESE, 2019, 卷号: 40, 期号: 8, 页码: 1600-1605 作者:  Yu Bingwen;  Jin Wei;  Jin Qinhan;  Liu Xu;  Li Xiaodong   |  收藏  |  浏览/下载：27/0  |  提交时间：2021/02/02 PEAK DETECTION  CORRECTION ALGORITHM  MASS-SPECTRA  CALIBRATION  Wavelength drift correction  Atomic emission spectrometry  Energy redistribution   Electrically tunable dual-wavelength organic laser based on holographic polymer dispersed liquid crystal grating 期刊论文  OAI收割 Organic Electronics, 2019, 卷号: 74, 页码: 161-165 作者:  L.J.Liu;  X.B.Kong;  Y.Q.Liu;  L.Sun;  L.Xuan   |  收藏  |  浏览/下载：42/0  |  提交时间：2020/08/24 Dual-wavelength laser,Electrically tunable,Low threshold,Holographic,polymer dispersed liquid,crystal grating,emission,nm,Materials Science,Physics   Selective biocompatibility and responsive imaging property of cationic conjugated polyelectrolyte to cancer cells 期刊论文  OAI收割 CHINESE CHEMICAL LETTERS, 2017, 卷号: 28, 期号: 10, 页码: 1975-1978 作者:  Wang, Bing;  Nie, Chenyao;  Liu, Libing;  Lv, Fengting;  Wang, Shu   |  收藏  |  浏览/下载：38/0  |  提交时间：2019/04/09 Imaging Cell  Conjugated Polymers  Fluorescence Enhancement  Long-wavelength Emission  Selective Biocompatibility
