| 1 | A chlorinated copolymer donor demonstrates a 18.13% power conversion efficiency显示文摘The rapid development of low-bandgap(LBG)nonfullerene acceptors and wide-bandgap(WBG)copolymer donors in recent years has boosted the power conversion efficiency(PCE)of organic solar cells(OSCs)to the 18%level[1−21].The commercialization of OSCs is highly expected.However,critical issues like the cost and the stability also determine whether OSCs can enter the market or not[22]. | Jianqiang Qin Lixiu Zhang Chuantian Zuo Zuo Xiao Yongbo Yuan Shangfeng Yang Feng Hao Ming Cheng Kuan Sun Qinye Bao Zhengyang Bin Zhiwen Jin and Liming Ding | 2021 | Journal of Semiconductors2021，42，1： | 19 |
| 2 | Progress of the key materials for organic solar cells显示文摘Organic solar cells have attracted academic and industrial interests due to the advantages like lightweight,flexibility and roll-to-roll fabrication.Nowadays,18%power conversion efficiency has been achieved in the state-of-the-art organic solar cells.The recent rapid progress in organic solar cells relies on the continuously emerging new materials and device fabrication technologies,and the deep understanding on film morphology,molecular packing and device physics.Donor and acceptor materials are the key materials for organic solar cells since they determine the device performance.The past 25 years have witnessed an odyssey in developing high-performance donors and acceptors.In this review,we focus on those star materials and milestone work,and introduce the molecular structure evolution of key materials.These key materials include homopolymer donors,D-A copolymer donors,A-D-A small molecular donors,fullerene acceptors and nonfullerene acceptors.At last,we outlook the challenges and very important directions in key materials development. | Yang Tong Zuo Xiao Xiaoyan Du Chuantian Zuo Yuelong Li Menglan Lv Yongbo Yuan Chenyi Yi Feng Hao Yong Hua Ting Lei Qianqian Lin Kuan Sun Dewei Zhao Chunhui Duan Xiangfeng Shao Wei Li Hin-Lap Yip Zhengguo Xiaol Bin Zhang Qingzhen Bian Yuanhang Cheng Shengjian Liu Ming Cheng Zhiwen Jin Shangfeng Yang Liming Ding | 2020 | Science China Chemistry2020，63，6： | 15 |
| 3 | Ginsenoside Rd inhibits apoptosis following spinal cord ischemia/reperfusion injury显示文摘Ginsenoside Rd has a clear neuroprotective effect against ischemic stroke. We aimed to verify the neuroprotective effect of ginsenoside Rd in spinal cord ischemia/reperfusion injury and explore its anti-apoptotic mechanisms. We established a spinal cord ischemia/reperfusion injury model in rats through the occlusion of the abdominal aorta below the level of the renal artery for 1 hour. Successfully established models were injected intraperitoneally with 6.25, 12.5, 25 or 50 mg/kg per day ginsenoside Rd. Spinal cord morphology was observed at 1, 3, 5 and 7 days after spinal cord ischemia/reperfusion injury. Intraperitoneal injection of ginsenoside Rd in ischemia/reperfusion injury rats not only improved hindlimb motor function and the morphology of motor neurons in the anterior horn of the spinal cord, but it also reduced neuronal apoptosis. The optimal dose of ginsenoside Rd was 25 mg/kg per day and the optimal time point was 5 days after ischemia/reperfusion. Immunohistochemistry and western blot analysis showed ginsenoside Rd dose-dependently inhibited expression of pro-apoptotic Caspase 3 and down-regulated the expression of the apoptotic proteins ASK1 and JNK in the spinal cord of rats with spinal cord ischemia/reperfusion injury. These findings indicate that ginsenoside Rd exerts neuroprotective effects against spinal cord ischemia/reperfusion injury and the underlying mechanisms are achieved through the inhibition of ASK1-JNK pathway and the down-regulation of Caspase 3 expression. | Baogang Wang Qingsan Zhu Xiaxia Man Li Guo Liming Hao | 2014 | Neural Regeneration Research2014，9，18： | 13 |
| 4 | Synergistic effects of elevated homocysteine level and abnormal blood lipids on the onset of stroke显示文摘Hyperhomocysteinemia and abnormal blood lipids are independent risk factors for stroke.However,whether both factors exert a synergistic effect in the onset of stroke remains unclear.The present study is a retrospective analysis of 2 089 cases of stroke and 2 089 control cases of simple intervertebral disk protrusion using a paired multivariate logistic regression method.Adjusting for known confounding variables including the patients’age,gender,smoking status,alcohol consumption status,patient and family medical history,and clinical biochemical indices,elevated homocysteine level was related to the onset of stroke.Patients with elevated homocysteine levels and abnormal blood lipids showed a 40.9%increase in the risk for stroke compared to patients with normal homocysteine levels and blood lipids(odds ratio 1.409;95%confidence interval1.127–1.761).These results indicate that elevated homocysteine and abnormal blood lipids exert synergistic effects in the onset of stroke.Patients with elevated homocysteine levels and abnormal blood lipids are predisposed to stroke. | Lu Hao Liming Chen Xiaoyong Sai Zhefeng Liu Guang Yang Rongzeng Yan Lili Wang Caiyun Fu Xuan Xu Zhenzhen Cheng Qiang Wu Shuzhang Li | 2013 | Neural Regeneration Research2013，8，31： | 9 |
| 5 | Protective effects of human umbilical cord mesenchymal stem cell-derived conditioned medium on ovarian damage显示文摘Chemotherapeutic agents are extensively used to treat malignancies.However,chemotherapy-induced ovarian damage and reduced fertility are severe side effects.Recently,stem cell transplantation has been reported to be an effective strategy for premature ovarian insufficiency(POI)treatment,but safety can still be an issue in stem cell-based therapy.Here,we show the protective effects of human umbilical cord mesenchymal stem cell-derived conditioned medium(hUCMSC-CM)on a cisplatin(Cs)-induced ovarian injury model.hUCMSC-CM can relieve Cs-induced depletion of follicles and preserve fertility.In addition,hUCMSC-CM can decrease apoptosis of oocytes and granulosa cells induced by Cs.RNA sequencing analysis reveals the differentially expressed genes of ovaries after Cs and hUCMSC-CM treatments,including genes involved in cell apoptosis.Furthermore,we show that the granulocyte colony-stimulating factor(G-CSF)/phosphatidylinositol 3-kinase(PI3K)/protein kinase B(Akt)pathway plays an important role in protecting granulosa cells from Cs-induced apoptosis.Together,we confirm the protective effects of hUCMSC-CM on ovarian reserve and fertility in mice treated with Cs,highlighting the remarkable therapeutic effects of hUCMSC-CM. | Liming Hong Long Yan Zhimin Xin Jie Hao Wenjing Liu Shuyu Wang Shujie Liao Hongmei Wang Xiaokui Yang | 2020 | Journal of Molecular Cell Biology2020，12，5： | 7 |
| 6 | Numerical and experimental investigation into hypersonic boundary layer transition induced by roughness elements显示文摘In this work, the Direct Numerical Simulation(DNS) and Oil-Film Interferometry(OFI)technique are used to investigate the hypersonic boundary layer transition induced by single and double roughness elements at Mach number 5. For single roughness, the DNS results showed that both horseshoe vortices and hairpin vortices caused by shear layer instability can affect the boundary layer instability. The generation of the near-wall unstable structure is the key point of boundary layer transition behind the roughness element. At the downstream of the roughness element, the interaction between horseshoe vortices and hairpin vortices will spread in the spanwise direction.For double roughness elements, the effect of the spacing between roughness elements on the transition is studied. It is found that the case of higher spacing between roughness elements is more effective for inducing transition than the lower one. The interaction between two adjacent roughness elements can suppress the evolution of horseshoe vortices in the downstream and trigger the instability of shear layer. Thus, the transition will be suppressed accordingly. | Hao DONG Shicheng LIU Xi GENG Song LIU Liming YANG Keming CHENG | 2019 | Chinese Journal of Aeronautics2019，32，3： | 6 |
| 7 | Myofiber necroptosis promotes muscle stem cell proliferation via releasing Tenascin-C during regeneration显示文摘Necroptosis,a form of programmed cell death,is characterized by the loss of membrane integrity and release of intracellular contents,the execution of which depends on the membrane-disrupting activity of the Mixed Lineage Kinase Domain-Like protein(MLKL)upon its phosphorylation.Here we found myofibers committed MLKL-dependent necroptosis after muscle injury.Either pharmacological inhibition of the necroptosis upstream kinase Receptor Interacting Protein Kinases 1(RIPK1)or genetic ablation of MLKL expression in myofibers led to significant muscle regeneration defects.By releasing factors into the muscle stem cell(MuSC)microenvironment,necroptotic myofibers facilitated muscle regeneration.Tenascin-C(TNC),released by necroptotic myofibers,was found to be critical for MuSC proliferation.The temporary expression of TNC in myofibers is tightly controlled by necroptosis;the extracellular release of TNC depends on necroptotic membrane rupture.TNC directly activated EGF receptor(EGFR)signaling pathway in MuSCs through its N-terminus assembly domain together with the EGF-like domain.These findings indicate that necroptosis plays a key role in promoting MuSC proliferation to facilitate muscle regeneration. | Shen'ao Zhou Wei Zhang Gaihong Cai Yingzhe Ding Caixia Wei Sheng Li Yu Yang Jie Qin Dan Liu Hao Zhang Xiexiang Shao Jianhua Wang Hongye Wang Wenjun Yang Huating Wang She Chen Ping Hu Liming Sun | 2020 | Cell Research2020，30，12： | 4 |
| 8 | The role of γ-aminobutyric acid in aluminum stress tolerance in a woody plant, Liriodendron chinense×tulipifera显示文摘The aluminum(Al)cation Al^(3+)in acidic soil shows severe rhizotoxicity that inhibits plant growth and development.Most woody plants adapted to acidic soils have evolved specific strategies against Al^(3+)toxicity,but the underlying mechanism remains elusive.The four-carbon amino acid gamma-aminobutyric acid(GABA)has been well studied in mammals as an inhibitory neurotransmitter;GABA also controls many physiological responses during environmental or biotic stress.The woody plant hybrid Liriodendron(L.chinense×tulipifera)is widely cultivated in China as a horticultural tree and provides high-quality timber;studying its adaptation to high Al stress is important for harnessing its ecological and economic potential.Here,we performed quantitative iTRAQ(isobaric tags for relative and absolute quantification)to study how protein expression is altered in hybrid Liriodendron leaves subjected to Al stress.Hybrid Liriodendron shows differential accumulation of several proteins related to cell wall biosynthesis,sugar and proline metabolism,antioxidant activity,cell autophagy,protein ubiquitination degradation,and anion transport in response to Al damage.We observed that Al stress upregulated glutamate decarboxylase(GAD)and its activity,leading to increased GABA biosynthesis.Additional GABA synergistically increased Al-induced antioxidant enzyme activity to efficiently scavenge ROS,enhanced proline biosynthesis,and upregulated the expression of MATE1/2,which subsequently promoted the efflux of citrate for chelation of Al^(3+).We also showed similar effects of GABA on enhanced Al^(3+)tolerance in Arabidopsis.Thus,our findings suggest a function of GABA signaling in enhancing hybrid Liriodendron tolerance to Al stress through promoting organic acid transport and sustaining the cellular redox and osmotic balance. | Pengkai Wang Yini Dong Liming Zhu Zhaodong Hao LingFeng Hu Xiangyang Hu Guibin Wang Tielong Cheng Jisen Shi Jinhui Chen | 2021 | Horticulture Research2021，8，1： | 3 |
| 9 | A Method to Implement Full Anonymous Attestation for Trusted Computing Platform显示文摘Trusted computing (TC) technology is brought out by trusted computing group (TCG) to make computing as safe and reliable as people expect. Attestation is one main function speci- fied by TCG, which is the means by which a trusted computer assures a remote computer whose platform is not tampered with. There are two protocols that implement attestation without dis- closing the platform’s real identity, which are Privacy CA-based protocol and direct anonymous attestation (DAA) protocol. However, in the first protocol the privacy CA is the bottleneck and the platform’s identity will be disclosed if the privacy CA is com- promise, while DAA protocol can do profiling when dealing with rogue hardware device. In this paper, we propose a DAA-extended new approach to ensure full anonymous attestation that can not only detect a rogue TPM, but also reveal rogue TPM’s real iden- tity. | HAO Liming SUN Xun YANG Shutang LU Songnian | 2007 | Wuhan University Journal of Natural Sciences2007，12，1： | 3 |
| 10 | Defect passivation by nontoxic biomaterial yields 21% efficiency perovskite solar cells显示文摘Defect passivation is one of the most important strategies to boost both the efficiency and stability of perovskite solar cells(PSCs).Here,nontoxic and sustainable forest-based biomaterial,betulin,is first introduced into perovskites.The experiments and calculations reveal that betulin can effectively passivate the uncoordinated lead ions in perovskites via sharing the lone pair electrons of hydroxyl group,promoting charge transport.As a result,the power conversion efficiencies of the p-i-n planar PSCs remarkably increase from 19.14%to 21.15%,with the improvement of other parameters.The hydrogen bonds of betulin lock methylamine and halogen ions along the grain boundaries and on the film surface and thus suppress ion migration,further stabilizing perovskite crystal structures.These positive effects enable the PSCs to maintain 90%of the initial efficiency after 30 days in ambient air with 60%±5%relative humidity,75%after 300 h aging at 85℃,and 55%after 250 h light soaking,respectively.This work opens a new pathway for using nontoxic and low-cost biomaterials from forest to make highly efficient and stable PSCs. | Shaobing Xiong Tianyu Hao Yuyun Sun Jianming Yang Ruru Ma Jiulong Wang Shijing Gong Xianjie Liu Liming Ding Mats Fahlman Qinye Bao | 2021 | Journal of Energy Chemistry2021，30，4： | 2 |

| 14 | UV light absorbers executing synergistic effects of passivating defects and improving photostability for efficient perovskite photovoltaics显示文摘Metal halide perovskite-based solar cells(PSCs) have rapidly-increased power conversion efficiency(PCE)exceeding 25% but poor stability especially under ultraviolet(UV) light. Meanwhile, non-radiative recombination caused by diverse defects in perovskite absorbers and related interfaces is one of the major factors confining further development of PSCs. In this study, we systematically investigate the role of 2-(2-hydroxy-5-methylphenyl)benzotriazole(UVP) additive in perovskite layers. By adjusting the amount of doped UVP, the quality of perovskite absorbers is significantly improved with enlarged grains, longer lifetime and diffusion length of charge carriers. Furthermore, UVP not only reduces defects for less nonradiative recombination, but also matches energy level alignment for efficient interfacial charge extraction. X-ray photoelectron spectroscopy confirms that N-donor of UVP molecule coordinates with undercoordinated Pb^(2+) on the surface. Interestingly, UVP incorporated in PbI_(2) protects the perovskite by absorbing UV through the opening and closing of the chelating ring. Eventually, the UVP treated PSCs obtain a champion PCE of 22.46% with remarkably enhanced UV stability, retaining over 90% of initial PCE after 60 m W/cm^(2) strong UV irradiation for 9 h while the control maintaining only 74%. These results demonstrate a promising strategy fabricating passivated and UV-resistant perovskite materials simultaneously for efficient and stable perovskite photovoltaics. | Jiale Li Wenjing Qi Yameng Li Sumin Jiao Hao Ling Peng Wang Xin Zhou Khumal Sohail Guangcai Wang Guofu Hou Jingshan Luo Ying Zhao Liming Ding Yuelong Li Xiaodan Zhang | 2022 | Journal of Energy Chemistry2022，31，4： | 1 |

| 17 | 4‑Terminal Inorganic Perovskite/Organic Tandem Solar Cells Offer 22%Efficiency显示文摘After fast developing of single-junction perovskite solar cells and organic solar cells in the past 10 years,it is becoming harder and harder to improve their power conversion efficiencies.Tandem solar cells are receiving more and more attention because they have much higher theoretical efficiency than single-junction solar cells.Good device performance has been achieved for perovskite/silicon and perovskite/perovskite tandem solar cells,including 2-terminal and 4-terminal structures.However,very few studies have been done about 4-terminal inorganic perovskite/organic tandem solar cells.In this work,semi-transparent inorganic perovskite solar cells and organic solar cells are used to fabricate 4-terminal inorganic perovskite/organic tandem solar cells,achieving a power conversion efficiency of 21.25%for the tandem cells with spin-coated perovskite layer.By using drop-coating instead of spin-coating to make the inorganic perovskite films,4-terminal tandem cells with an efficiency of 22.34%are made.The efficiency is higher than the reported 2-terminal and 4-terminal inorganic perovskite/organic tandem solar cells.In addition,equivalent 2-terminal tandem solar cells were fabricated by connecting the sub-cells in series.The stability of organic solar cells under continuous illumination is improved by using semi-transparent perovskite solar cells as filter. | Ling Liu Hanrui Xiao Ke Jin Zuo Xiao Xiaoyan Du Keyou Yan Feng Hao Qinye Bao Chenyi Yi Fangyang Liu Wentao Wang Chuantian Zuo Liming Ding | 2023 | Nano-Micro Letters2023，15，2： | 1 |

| 19 | Down-staging depth score could be a survival predictor for locally advanced gastric cancer patients after preoperative chemoradiotherapy显示文摘Objective:The predictive effect of preoperative chemoradiotherapy(CRT)is low and difficult in guiding individualized treatment.We examined a surrogate endpoint for long-term outcomes in locally advanced gastric cancer patients after preoperative CRT.Methods:From April 2012 to April 2019,95 patients with locally advanced gastric cancer who received preoperative concurrent CRT and who were enrolled in three prospective studies were included.All patients were stage T_(3/4) N_(+).Local control,distant metastasis-free survival(DMFS),disease-free survival(DFS)and overall survival(OS)were evaluated.Clinicopathological factors related to long-term prognosis were analyzed using univariate and multivariate analyses.The down-staging depth score(DDS),which is a novel method of evaluating CRT response,was used to predict long-term outcomes.Results:The median follow-up period for survivors was 30 months.The area under the curve(AUC)of the receiver operating characteristic(ROC)curve predicted by the DDS was 0.728,which was better than the pathological complete response(pCR),histological response and ypN0.Decision curve analysis further affirmed that DDS had the largest net benefit.The DDS cut-off value was 4.pCR and ypN0 were associated with OS(P=0.026 and 0.049).Surgery and DDS are correlated with DMFS,DFS and OS(surgery:P=0.001,<0.001 and<0.001,respectively;and DDS:P=0.009,0.013 and 0.032,respectively).Multivariate analysis showed that DDS was an independent prognostic factor of DFS(P=0.021).Conclusions:DDS is a simple,short-term indicator that was a better surrogate endpoint than pCR,histological response and ypN0 for DFS. | Ning Li Xin Wang Yuan Tang Dongbin Zhao Yihebali Chi Lin Yang Liming Jiang Jun Jiang Jinming Shi Wenyang Liu Hua Ren Hui Fang Yu Tang Bo Chen Ningning Lu Hao Jing Shunan Qi Shulian Wang Yueping Liu Yongwen Song Yexiong Li Jing Jin | 2021 | Chinese Journal of Cancer Research2021，33，4： | 1 |
| 20 | Improving tensile-shear properties of friction stir lap welded dissimilar Al/Mg joints by eliminating hook defect and controlling interfacial reaction显示文摘To improve tensile-shear properties of fiction stir lap welded(FSLW) dissimilar Al/Mg joints, pin-tip profiles were innovatively designed and welding speed was optimized, and effects of them on formation, interface microstructure and mechanical properties of different FSLW joints were investigated. With increasing the welding speed, the tensile-shear load of FSLW joints produced by three pins presents an increasing firstly and then decreasing trend. Compared with Rpin, the hook and hole defect in the joints made by S-pin and T-pin are eliminated owing to additional eccentric force. Moreover, the joints obtained by T-pin at 75 mm/min have the highest tensile-shear load, and a maximum value of 3.425 kN is produced, which increases by 96.8%.Meanwhile, the pin-tip profile improves significantly the interface reaction depending on the welding temperature. For R-pin, thick brittle intermetallic compounds of about 6.9 μm Al3Mg2and 13.3 μm Al12Mg17layers at the welding interface derived from diffusion reaction are formed, resulting in continuous cracks. However, using T-pin can raise the interface temperature, and which makes the interface liquefy locally to generate only 2.2 μm Al3Mg2layer and dispersive(Al12-Mg17+Mg) eutectic structure. This can release high residual stress and remove welding crack, consequently enhancing the interface properties of T-pin joints. | Yuqing MAO Ping YANG Wenyan ZHANG Ning LI Hao NIE Danyang LIN Liming KE | 2023 | Chinese Journal of Aeronautics2023，36，7： | 1 |
