In this study, we present the investigation of nonstationary QPPs with multiple periods during the impulsive phase of a powerful flare on 2017 September 6, which were simultaneously measured by the Hard X-ray Modulation Telescope (Insight-HXMT), as well as the ground-based BLENSW. The multiple periods, detected by applying a wavelet transform and Lomb-Scargle periodogram to the detrended light curves, are found to be ~20-55 s in the Ly`and mid-ultraviolet Balmer continuum emissions during the flare impulsive phase. Similar QPPs with multiple periods are also found in the hard X-ray emission and low-frequency radio emission. Our observations suggest that the flare QPPs could be related to nonthermal electrons accelerated by the repeated energy release process, i.e., triggering of repetitive magnetic reconnection, while the multiple periods might be modulated by the sausage oscillation of hot plasma loops. For the multiperiodic pulsations, other generation mechanisms could not be completely ruled out.   Photothermal-Responsive Single-Walled Carbon Nanotube-Based Ultrathin Membranes for On/Off Switchable Separation of Oil-in-Water Nanoemulsions 期刊论文  OAI收割 ACS NANO, 2015, 卷号: 9, 期号: 5, 页码: 4835-4842 作者:  Hu, Liang;  Gao, Shoujian;  Ding, Xianguang;  Wang, Dong;  Jiang, Jiang 收藏  |  浏览/下载：16/0  |  提交时间：2015/10/29 photothermal responsivity  ultrathin membrane  oil-in-water nanoemulsion  light-modulated flux  emulsion separation   Photothermal-Responsive Single-Walled Carbon Nanotube-Based Ultrathin Membranes for On/Off Switchable Separation of Oil-in-Water Nanoemulsions 期刊论文  OAI收割 ACS NANO, 2015, 卷号: 9, 期号: 5, 页码: 8 作者:  Hu, L(胡亮);  Gao, SJ(高守建);  Ding, XG(丁显光);  Wang, D(王栋);  Jiang, J(姜江) 收藏  |  浏览/下载：83/0  |  提交时间：2015/12/31 photothermal responsivity  ultrathin membrane  oil-in-water nanoemulsion  light-modulated flux  emulsion separation
