| 1 | Thiolactone copolymer donor gifts organic solar cells a 16.72% efficiency显示文摘Since 1995,bulk-heterojunction organic solar cells consisting of one or two organic donors and one or two organic acceptors have been fighting for high power conversion efficiencies(PCEs)and good stability[1].Until recent years,this next-generation photovoltaic technology starts to offer decent PCEs,shedding the light on commercialization,and attracting great attention again[2-14].Compared w让h the continuously emerging highperformance nonfullerene acceptors,high-performance donors are rare. | Ji Xiong Ke Jin Yufan Jiang Jianqiang Qin Tan Wang Jinfeng Liu Qishi Liu Haili Peng Xiongfeng Li Anxin Sun Xianyi Meng Lixiu Zhang Ling Liu Wenting Li Zhimin Fang Xue Jia Zuo Xiao Yaqing Feng Xiaotao Zhang Kuan Sun Shangfeng Yang Shengwei Shi Liming Ding | 2019 | Science Bulletin2019，64，21： | 17 |
| 2 | Interface engineering gifts CsPbI2.25Br0.75 solar cells high performance显示文摘Organic-inorganic halide perovskite (ABX3) solar cells (PSCs)have made great progress in recent years [1]. The power conversion efficiency (PCE) has increased up to 25.2%(NREL Best Research-Cell Efficiency Chart, https://www.nrel.gov/pv/cell-efficiency.html, Accessed August 2019). However, they suffer from poor thermal stability due to the volatile A-site organic cations. | Zhimin Fang Xianyi Meng Chuantian Zuo Dan Li Zuo Xiao Chenyi Yi Mingkui Wang Zhiwen Jin Shangfeng Yang Liming Ding | 2019 | Science Bulletin2019，64，23： | 11 |
| 3 | Side chain engineering on D18 polymers yields 18.74%power conversion efficiency显示文摘Donor-acceptor(D-A)conjugated copolymers contain-ing fused-ring acceptor units demonstrate outstanding per-formance in organic solar cells(OSCs)[1−13].We have in-vented highly efficient D-A copolymer donors D18 and D18-Cl by using a fused-ring acceptor unit,dithieno[3′,2′:3,4;2″,3″:5,6]benzo[1,2-c][1,2,5]thiadiazole(DTBT)[1,2].OSCs with D18 or D18-Cl gave power conversion efficiencies(PCEs)of 18.56%and 18.69%,respectively[3,4].Side chain engineering is an effective approach to improve the per-formance of conjugated polymers in optoelectronic devi-ces[14−16].The alkyl side chains not only determine polymers’solubility,but also influence their crystallinity and mobility.In this work,we develop two efficient donors D18-B and D18-Cl-B via side chain engineering on D18 polymers(Fig.1(a)).These donors offer PCEs up to 18.74%(certified 18.2%)in tern-ary OSCs. | Xianyi Meng Ke Jin Zuo Xiao Liming Ding | 2021 | Journal of Semiconductors2021，42，10： | 2 |
| 4 | Multiresolution processing for source detection and localization显示文摘The conventional BF/MFP (beamforming/matched field processing) or BF/MFP based on subspace axe traditional array signal processing methods for source's detection and location, they axe all belonging to singe-resolution processing. In fact, the array signal has multiresolution structure, which is worthy of exploiture and utilization to enhance the ability of detection and location, especially to improve the robustness for BF/MFP. The time-space multiresolution modeling of multipath transmitted wave and the corresponding multiresolution focused processing axe investigated, and it is shown from the analysis of actual sea-trial data that the performance of MFP can be improved. | DING Feng GONG Xianyi(State Key Laboratory of Ocean Acoustics, Hangzhou Applied Acoustics Research InstituteZhejiang Fuyang 311400) | 2003 | Chinese Journal of Acoustics2003，22，3： | 0 |
| 5 | Banana-shaped electron acceptors with an electron-rich core fragment and 3D packing capability显示文摘The emergence of Y6-type nonfullerene acceptors has greatly enhanced the power conversion efficiency(PCE)of organic solar cells(OSCs).However,which structural feature is responsible for the excellent photovoltaic performance is still under debate.In this study,two Y6-like acceptors BDOTP-1 and BDOTP-2 were designed.Different from previous Y6-type acceptors featuring an A–D–Aʹ–D–A structure,BDOTP-1,and BDOTP-2 have no electron-deficient Aʹfragment in the core unit.Instead,there is an electron-rich dibenzodioxine fragment in the core.Although this modification leads to a marked change in the molecular dipole moment,electrostatic potential,frontier orbitals,and energy levels,BDOTP acceptors retain similar three-dimensional packing capability as Y6-type acceptors due to the similar banana-shaped molecular configuration.BDOTP acceptors show good performance in OSCs.High PCEs of up to 18.51%(certified 17.9%)are achieved.This study suggests that the banana-shaped configuration instead of the A–D–Aʹ–D–A structure is likely to be the determining factor in realizing high photovoltaic performance. | Pengqi Li Xianyi Meng Ke Jin Zhiwei Xu Jianqi Zhang Lixiu Zhang Chuang Niu Furui Tan Chenyi Yi Zuo Xiao Yaqing Feng Guan-Wu Wang Liming Ding | 2023 | Carbon Energy2023，5，1： | 0 |
| 6 | Long-term exercise training inhibits inflammation by suppressing hippocampal NLRP3 in APP/PS1 mice显示文摘Behavioral experiments have demonstrated that long-term physical exercise can be beneficial for learning and memory dysfunction caused by neuroinflammation in Alzheimer's disease(AD).However,the molecular mechanism remains poorly understood due to a lack of sufficient pertinent biochemical evidence.We investigated the potential effect of long-term physical exercise on cognition and hippocampal gene and protein expression changes in a transgenic AD mouse model.Following twenty weeks of treadmill exercise,transgenic AD mice showed improvement in cognitive functions and downregulation of Nod-like receptor protein 3(NLRP3)(p<0.01),interleukin-1beta(IL-1β)(p<0.05),and amyloid-β1-42(Aβ1-42)(p<0.05)expression levels.In addition,we observed significant reductions of microglial activation and hippocampal neuronal damage in the exercised AD mice(p<0.01),which might be a result of the downregulation of NLRP3-mediated signaling and neuroinflammatory responses.As neuronal damage due to inflammation might be a likely cause of AD-associated cognitive dysfunction.Our results suggested that the anti-inflammatory effects of exercise training involved downregulating the expression of key inflammatory factors and might play an important role in protecting hippocampal neurons against damage during the course of AD. | Xue Li Yu Jin Xianyi Ding Tongyang Zhu Changling Wei Li Yao | 2023 | Sports Medicine and Health Science2023，5，4： | 0 |
