| 1 | 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 | Observational responses of stratospheric sudden warming to blocking highs and its feedbacks on the troposphere显示文摘The influences of tropospheric blocking high on the stratospheric sudden warming (SSW) and the SSW-induced feedback on the lower atmosphere are analyzed with NCEP (National Center for Environmental Prediction) 2 reanalysis data. Daily mean data from 1979 to 2010 are used to perform statistical and dynamical analyses. According to different distribution features of polar vortex, which can be ascribed to different activities of blocking highs, we have obtained two warming patterns in vortex splitting and displacement patterns. For vortex splitting events, in the Eurasian-North American (ENA) paratype, with disturbances of Atlantic and Aleutian blocking highs, polar vortex is split into two parts that locate at Eurasian and North American continents respectively, while in the Atlantic-East Asian (AEA) paratype, two low-pressure centers derived from the split vortex are situated in the Atlantic and East Asian regions, and two blocking systems occurring in the Urals and North American areas precede these splitting processes. For vortex displacement events, in the Aleutian-Intrusion (AI) paratype, the polar vortex is displaced to the west European and Atlantic areas by the intrusive Aleutian high and this pattern always corresponds to the blocking events occurring in the Pacific basin only. Similarly, the vortex is pushed to the west Eurasian continent by the intrusive North American high-pressure system in the North American-Intrusion (NAI) paratype, which is closely related to the blocking over these areas. The second subject of the research is that whether the anomalous stratospheric signals can be propagated to the lower atmosphere, which is depended on the intensity, duration and position of the disturbed vortex. According to our case studies, geopotential height anomalies can be propagated to the troposphere in strong SSW years, taking about 10-15 d for the decrease from 10 to 500 hPa, leading to apparent variations in the geopotential height and temperature fields. | LU ChunHui DING YiHui | 2013 | Chinese Science Bulletin2013，58，12： | 6 |
| 4 | Space Flight Validation of Design and Engineering of the ZDPS-1A Pico-satellite显示文摘The ZDPS-1A pico-satellites are the first satellites in China within the 1-10 kg mass range that are successfully operated on orbit. Unlike common pico-satellites, they are designed to be 'larger but stronger' with more powerful platforms and unique payloads so as to bear a better promise for real applications. Through their space flight mission, the functionality and performance of the two flight models are tested on orbit and validated to be mostly normal and in consistency with design and ground tests with only several inconforming occasions. Moreover, they have worked properly on orbit for one year so far, well exceeding their life expectancy of three months. Therefore, the space flight mission has reached all its goals, and verified that the design concept and the engineering process of the picosatellites are sufficient in allowing them the desired functionality and performance in, and the adaption to the launch procedure and the low-Earth orbit space environment. In the foreseeable future, the platform together with the design concept and the engineering process of the pico-satellites are expected to be applied to more complicated real space applications. | YANG Mu WANG Hao WU Changju WANG Chunhui DING Licong ZHENG Yangming JIN Zhonghe | 2012 | Chinese Journal of Aeronautics2012，25，5： | 5 |
| 5 | Atomic-scale mechanism of the θ’’→θ’ phase transformation in Al-Cu alloys显示文摘The phase transformation of θ’’→θ’ in an Al-5.7 Cu alloy was investigated by aberration-corrected scanning transmission electron microscopy, and the tranformation mode of θ’’→θ’ during aging treatment was clarified. In the presence of the θ’ phases, θ’ was found to be formed by in-situ transformation fromθ’’ with the same plate shape, size and broad faces. The transformation starts from multiple sites within the θ’ precipitate and the whole θ’ phase finally forms as the preferential θ’ sections grow and connect with each other. Antiphase domain boundaries are also found in some θ’ precipitates when the disregistry exists between different θ’ sections. | Zhenju Shen Qingqing Ding Chunhui Liu Jiangwei Wang He Tian Jixue Li Ze Zhang | 2017 | Journal of Materials Science & Technology2017，33，10： | 3 |
| 6 | Interdecadal Variability of Summer Precipitation in Northwest China and Associated Atmospheric Circulation Changes显示文摘Daily precipitation data from 149 rain gauge stations in China and NCEP-NCAR reanalysis data during 1961-2018are used to investigate the interdecadal variability of summer precipitation in Northwest China and related causes.The results suggest that,on the interdecadal timescale,Northwest China shifts into a rainy period from the year 1987,with an increase in the precipitation amount and intensity;an increase in the probability of moderate rain,heavy rain,torrential rain,and extremely heavy rain;and a decrease in the probability of light rain.More than 60%of the increase in precipitation can be attributed to rainfall with intensity above the grade of heavy rain.The associated interdecadal variability of atmospheric circulations over midlatitude Eurasia in summer is examined and it is found that the interdecadal variability is mainly characterized by the Silk Road pattern(SRP),with a cyclonic circulation anomaly and an anticyclonic circulation anomaly over central Asia and Mongolia,respectively;enhanced ascending motion and atmospheric instability in Northwest China;and strengthened easterly winds caused by the Mongolian anticyclonic anomaly along the northern boundary of the Tibetan Plateau.On the south side of the Mongolian anticyclone,the water vapor transported from the Pacific and Indian Oceans as well as the South China Sea to Northwest China by easterly winds increases significantly,providing the main water vapor source for the increase in precipitation in Northwest China on the interdecadal timescale.The transition of the Atlantic multidecadal oscillation to a positive phase may be the main cause of the interdecadal transition of the SRP to a positive phase,resulting in the interdecadal increase in summer precipitation in Northwest China. | Tong XUE Yihui DING Chunhui LU | 2022 | Journal of Meteorological Research2022，36，6： | 2 |
| 7 | Optimization of bits allocation and path planning with trajectory constraint in UAV-enabled mobile edge computing system显示文摘In this paper,an Unmanned Aerial Vehicle(UAV)enabled Mobile Edge Computing(MEC)system is studied,in which UAV acts as server to offer computing offloading service to the Mobile Users(MUs)with limited computing capability and energy budget.We aim to minimize the total energy consumption of MUs by jointly optimizing the bit allocation for uplink,computing at the UAV and downlink,along with the UAV trajectory in a unified framework.To this end,a trajectory constraint model is employed to avoid sudden changes of velocity and acceleration during flying.Due to high-order information in use,we lead to a more reasonable nonconvex optimization problem than prior arts.An Alternating Direction Method of Multipliers(ADMM)method is introduced to solve the optimization problem,which is decomposed into a set of easy subproblems,to meet the requirement on the efficiency in edge computing.Numerical results demonstrate that our approach leads a smoother UAV trajectory,significantly save the energy consumption for UAV during flying. | Yizhe LUO Wenrui DING Baochang ZHANG Wenqian HUANG Chunhui LIU | 2020 | Chinese Journal of Aeronautics2020，33，10： | 2 |

| 9 | Effect of warming moxibustion Tianshu(ST 25, bilateral) and Qihai(CV 6) for the treatment of diarrhea-dominant irritable bowel syndrome: a patient-blinded pilot trial with orthogonal design显示文摘OBJECTIVE: To investigate the effects of warming moxibustion Tianshu(ST 25, bilateral) and Qihai(CV6) in patients with diarrhea-dominant irritable bowel syndrome(D-IBS) by assessing predominant factors, and determining the best factor combinations and their interactions. To identify the optimal quantity of warming moxibustion Tianshu(ST 25, bilateral) and Qihai(CV 6) to achieve optimal efficacy.METHODS: An L9(3~4) orthogonal design was applied to 233 confirmed subjects based on the three most influential factors and the three most frequently used levels. Nine programs were designed.Subjects were assigned to four subgroups according to age and gender; each subject underwent one of the nine programs randomly. We selected Tianshu(ST 25, bilateral) and Qihai(CV 6). The scores of symptoms and the IBS Quality of Life(IBS-QOL) were evaluated after the final treatment.RESULTS: After treatment, clinical symptoms of all patients were significantly improved(P = 0.001).Quality of life also improved significantly(P < 0.05).For all the participants, frequency was the dominating factor regarding symptoms(P = 0.01). Duration was the dominating factor for quality of life(P =0.0001). The best combination for improving symptoms in 30-40-year-old male and female patients was two courses of 10 min each once a day, and for41-50-year-old male and female patients it was three courses of 10 min(males) or 30 min(females)twice a day. The best combination for quality of life was three courses of 20 min once a day. No interaction was found between frequency and course, or frequency and duration.CONCLUSION: Warming moxibustion Tianshu(ST25, bilateral) and Qihai(CV 6) is a promising therapy for D-IBS. To acquire optimal efficacy, the three main factors(duration, frequency and treatment course) of the warming moxibustion should reach a specific quantity and be combined appropriately. | Yang Ling Lu Yuan Zhang Haifeng Ma Xiaopeng Bao Chunhui Wu Huangan Zhao Chen Ding Guanghong Qi Li Zhou Shuang | 2017 | Journal of Traditional Chinese Medicine2017，37，4： | 1 |
| 10 | Preorganization boosts the artificial esterase activity of a self-assembling peptide显示文摘The creation of artificial enzymes to mimic natural enzymes remains a great challenge owing to the complexity of the structural arrangement of the essential amino acids in catalytic centers.In this study,we used the phosphatase-based enzyme-instructed self-assembly(EISA)to supervise artificial esterases'final structures and catalytic activities.We reported that peptide precursors containing different phosphorylation sites could preorganize into alternated nanostructures and undergo dephosphorylation in the presence of alkaline phosphatase(ALP)with variation in kinetic and thermodynamic profiles.Although identical self-assembly compositions were formed after dephosphorylation,precursors with more enhanced preorganized states tended to better promote ALP dephosphorylation,facilitate further self-assembly,and strengthen the catalytic activities of the final assemblies.We envisioned that our strategy would be useful for further construction and manipulation of various artificial enzymes with superior catalytic activities. | Yaoxia Chen Wenwen Zhang Yinghao Ding Chunhui Liang Yang Shi Zhi-Wen Hu Ling Wang Zhimou Yang | 2021 | Science China Chemistry2021，64，9： | 1 |

| 13 | The Data-Reusing MCC-Based Algorithm and Its Performance Analysis显示文摘Maximum correntropy criterion(MCC)provides a robust optimality criterion for non-Gaussian signal processing.In this paper,the weight update equation of the conventional MCC-based adaptive filtering algorithm is modified by reusing the past K input vectors,forming a class of data-reusing MCC-based algorithm,called DRMCC algorithm.Comparing with the conventional MCCbased algorithm,the DR-MCC algorithm provides a much better convergence performance when the input data is correlated.The mean-square stability bound of the DRMCC algorithm has been studied theoretically.For both Gaussian noise case and non-Gaussian noise case,the expressions for the steady-state Excess mean square error(EMSE) of DR-MCC algorithm have been derived.The relationship between the data-reusing order and the steadystate EMSEs is also analyzed.Simulation results are in agreement with the theoretical analysis. | LIU Chunhui QI Yue DING Wenrui | 2016 | Chinese Journal of Electronics2016，25，4： | 1 |

| 15 | Generation of inactivated IL2RG and RAG1 monkeys with severe combined immunodeficiency using base editing显示文摘Severe combined immunodeficiency(SCiD)encompasses a range of inherited disorders that lead to a profound deterioration of the immune system.Among the pivotal genes associated with SCID,RAG1 and IL2RG play crucial roles.IL2RG is essential for the development,differentiation,and functioning of T,B,and NK cells,while RAG1 critically contributes to adaptive immunity by facilitating V(D)J recombination during the maturation of lymphocytes.Animal models carrying mutations in these genes exhibit notable deficiencies in their immune systems. | Xiao Zheng Chunhui Huang Yingqi Lin Bofeng Han Yizhi Chen Caijuan Li Jiawei Li Yongyan Ding Xichen Song Wei Wang Weien Liang Jianhao Wu Jiaxi Wu Jiale Gao Chengxi Wei Xudong Zhang Zhuchi Tu Sen Yan | 2023 | Signal Transduction and Targeted Therapy2023，8，10： | 0 |
| 16 | Ultra-thin robust CNT@GC film integrating effective electromagnetic shielding and flexible Joule heating显示文摘The demand for lightweight,thin electromagnetic interference(EMI)shielding film materials with high shielding effectiveness(SE),excellent mechanical properties,and stability in complex environments is particularly pronounced in the realm of flexible and portable electronic products.Here,we developed an ultra-thin film(CNT@GC)in which the glassy carbon(GC)layer wrapped around and welded carbon nanotubes(CNTs)to form a core-shell network structure,leading to exceptional tensile strength(327.2 MPa)and electrical conductivity(2.87×10^(5) S·m^(−1)).The CNT@GC film achieved EMI SE of 60 dB at a thickness of 2µm after post-acid treatment and high specific SE of 3.49×10^(5) dB·cm^(2)·g^(−1),with comprehensive properties surpassing those of the majority of previous shielding materials.Additionally,the CNT@GC film exhibited Joule heating capability,reaching a surface temperature of 135℃at 3 V with a fast thermal response of about 0.5 s,enabling anti-icing/de-icing functionality.This work presented a methodology for constructing a robust CNT@GC film with high EMI shielding performance and exceptional Joule heating capability,demonstrating immense potential in wearable devices,defense,and aerospace applications. | Ding Zhang Chunhui Wang Meng Li Weixue Meng Shipeng Zhang Mengdan Yang Xinguang Huang Yingjiu Zhang Yuanyuan Shang Anyuan Cao | 2024 | Nano Research2024，17，5： | 0 |

| 18 | The DEAD-box RNA helicase ZmRH48 is required for the splicing of multiple mitochondrial introns,mitochondrial complex biosynthesis,and seed development in maize显示文摘RNA helicases participate in nearly all aspects of RNA metabolism by rearranging RNAs or RNA–protein complexes in an adenosine triphosphatedependent manner.Due to the large RNA helicase families in plants,the precise roles of many RNA helicases in plant physiology and development remain to be clarified.Here,we show that mutations in maize(Zea mays)DEAD-box RNA helicase48(Zm RH48)impair the splicing of mitochondrial introns,mitochondrial complex biosynthesis,and seed development.Loss of Zm RH48 function severely arrested embryogenesis and endosperm development,leading to defective kernel formation.Zm RH48 is targeted to mitochondria,where its deficiency dramatically reduced the splicing efficiency of five cis-introns(nad5 intron 1;nad7 introns 1,2,and 3;and ccm Fc intron 1)and one trans-intron(nad2 intron 2),leading to lower levels of mitochondrial complexes I andⅢ.Zm RH48 interacts with two unique pentatricopeptide repeat(PPR)proteins,PPR-SMR1 and SPR2,which are required for the splicing of over half of all mitochondrial introns.PPR-SMR1 interacts with SPR2,and both proteins interact with P-type PPR proteins and Zm-m CSF1 to facilitate intron splicing.These results suggest that Zm RH48 is likely a component of a splicing complex and is critical for mitochondrial complex biosynthesis and seed development. | Yan-Zhuo Yang Shuo Ding Xin-Yuan Liu Chunhui Xu Feng Sun Bao-Cai Tan | 2023 | Journal of Integrative Plant Biology2023，65，11： | 0 |
| 19 | Geological context and vents morphology in the ultramafic-hosted Tianxiu field, Carlsberg Ridge显示文摘The Tianxiu hydrothermal field(TXHF) located on Carlsberg Ridge is one of the few active ultramafic-hosted venting systems known in the Indian Ocean. Despite numerous investigations, there is limited understanding of its sulfide structure morphology, and the factors controlling the formation of TXHF are poorly understood. In this study, we conducted detailed seafloor mapping using visual data obtained by dives using the human-occupied vehicle(HOV) Jiaolong. The TXHF is found to be an active, off-axis, ultramafic-hosted, high-temperature hydrothermal area in which serpentine peridotite is exposed. Two main hydrothermal sites were identified, i.e., P and Y, both of which feature a complex of chimneys and beehive diffusers constituting a “chimney jungle” and isolated large steep-sided structures developed on flat-lying sulfide mounds. In addition, some sporadic inactive chimneys and outcrops of hydrothermal deposits were noted. The chimneys are rich in Fe and Zn sulfide, and lack the central fluid channel formed by focused high-temperature fluid flow. Hydrothermal venting at TXHF is likely related to low-angle detachment faults that focus and transport hydrothermal fluids away from a heat source along the valley wall. Our results complement and expand upon previous works concerning sulfide chimney morphology and their corresponding mineral paragenesis in ultramafic-hosted hydrothermal systems in the Indian Ocean and further our understanding of modern seafloor hydrothermal systems. | Jin Liang Chunhui Tao Xiangxin Wang Cheng Su Wei Gao Yadong Zhou Weikun Xu Xiaohe Liu Zhongjun Ding | 2023 | Acta Oceanologica Sinica2023，42，9： | 0 |
| 20 | Efficiency-loss analysis of monolithic perovskite/silicon tandem solar cells by identifying the patterns of a dual two-diode model’s current-voltage curves显示文摘In this work,we developed a simple and direct circuit model with a dual two-diode model that can be solved by a SPICE numerical simulation to comprehensively describe the monolithic perovskite/crystalline silicon(PVS/c-Si)tandem solar cells.We are able to reveal the effects of different efficiency-loss mechanisms based on the illuminated current density-voltage(J-V),semi-log dark J-V,and local ideality factor(m-V)curves.The effects of the individual efficiency-loss mechanism on the tandem cell’s efficiency are discussed,including the exp(V/VT)and exp(V/2VT)recombination,the whole cell’s and subcell’s shunts,and the Ohmic-contact or Schottky-contact of the intermediate junction.We can also fit a practical J-V curve and find a specific group of parameters by the trial-and-error method.Although the fitted parameters are not a unique solution,they are valuable clues for identifying the efficiency loss with the aid of the cell’s structure and experimental processes.This method can also serve as an open platform for analyzing other tandem solar cells by substituting the corresponding circuit models.In summary,we developed a simple and effective methodology to diagnose the efficiency-loss source of a monolithic PVS/c-Si tandem cell,which is helpful to researchers who wish to adopt the proper approaches to improve their solar cells. | Yuheng Zeng Zetao Ding Zunke Liu Wei Liu Mingdun Liao Xi Yang Zhiqin Ying Jingsong Sun Jiang Sheng Baojie Yan Haiyan He Chunhui Shou Zhenhai Yang Jichun Ye | 2023 | Journal of Semiconductors2023，44，8： | 0 |
