| 1 | Oxygen‑Deficient β‑MnO_(2)@Graphene Oxide Cathode for High‑Rate and Long‑Life Aqueous Zinc Ion Batteries显示文摘Recent years have witnessed a booming interest in grid-scale electrochemical energy storage,where much attention has been paid to the aqueous zinc ion batteries(AZIBs).Among various cathode materials for AZIBs,manganese oxides have risen to prominence due to their high energy density and low cost.However,sluggish reaction kinetics and poor cycling stability dictate against their practical application.Herein,we demonstrate the combined use of defect engineering and interfacial optimization that can simultaneously promote rate capability and cycling stability of MnO_(2) cathodes.β-MnO_(2) with abundant oxygen vacancies(VO)and graphene oxide(GO)wrapping is synthesized,in which VO in the bulk accelerate the charge/discharge kinetics while GO on the surfaces inhibits the Mn dissolution.This electrode shows a sustained reversible capacity of~129.6 mAh g^(−1) even after 2000 cycles at a current rate of 4C,outperforming the state-of-the-art MnO_(2)-based cathodes.The superior performance can be rationalized by the direct interaction between surface VO and the GO coating layer,as well as the regulation of structural evolution ofβ-MnO_(2) during cycling.The combinatorial design scheme in this work offers a practical pathway for obtaining high-rate and long-life cathodes for AZIBs. | Shouxiang Ding Mingzheng Zhang Runzhi Qin Jianjun Fang Hengyu Ren Haocong Yi Lele Liu Wenguang Zhao Yang Li Lu Yao Shunning Li Qinghe Zhao Feng Pan | 2021 | Nano-Micro Letters2021，13，11： | 3 |
| 2 | Layer-by-layer slot-die coated high-efficiency organic solar cells processed using twin boiling point solvents under ambient condition显示文摘Layer-by-layer (LbL) strategy has been developed to form bulk heterojunction (BHJ) structure for processing efficient organic solar cells (OSCs). Herein, LbL slot-die coating with twin boiling point solvents (TBPS) strategy was developed to fabricate highly efficient OSCs, which matches with large-scale, high throughput roll-to-roll (R2R) industrialized mass process. The TBPS strategy could produce high-quality thin film without any additive, leading to the optimized vertical phase separation with interpenetrating nanostructures, as well as the enhanced charge transport and extraction. Thus, the power conversion efficiency up to 14.42% was achieved for [(2,6-(4,8-bis(5-(2-ethylhexyl-3-fluoro)thiophen-2-yl)-benzo [1,2-b:4,5-b′]dithiophene))-alt-(5,5-(1′,3′-di-2-thienyl-5′,7′-bis(2-ethylhexyl)benzo[1′,2′-c:4′,5′-c′]dithiophene-4,8-dione)]:2,2′-((2Z,2′Z)-((12,13-bis(2-ethylhexyl)-3,9-diundecyl-12,13-dihydro-[1,2,5]thiadiazolo[3,4-e]thieno[2″,3″:4″,5″]thieno[2′,3′:4,5]pyrrolo[3,2-g]thieno[2′,3′:4,5]thieno[3,2-b]indole-2,10-diyl)bis(methanylylidene)) bis(5,6-difluoro-3-oxo-2,3-dihydro-1H-indene-2,1-diylidene))dimalononitrile (PM6:Y6) OSCs fabricated via sequentially LbL slot-die coating using the TBPS strategy under ambient condition. The research provides a potential route for industrialized production of high-efficiency and large-area OSC devices. | Yu Yang Erming Feng Hengyue Li Zichao Shen Wanrong Liu Jingbo Guo Qun Luo Jidong Zhang Guanghao Lu Changqi Ma Junliang Yang | 2021 | Nano Research2021，14，11： | 1 |
| 3 | Preparation of quaternarized N-halamine-grafted graphene oxide nanocomposites and synergetic antibacterial properties显示文摘At present,frequent outbreaks of bacteria and viruses have seriously affected people's normal lives.Therefore,the study of broad-spectrum antibacterial nanocomposites is very promising.However,most antibacterial materials have some disadvantages,such as single bactericidal mechanisms and unrepeatable use.Based on the current situation,a kind of nanocomposite with three structures of graphene oxide(GO),quaternary ammonium salt(QAs)and N-halamine was prepared,which showed synergistic effect to improve antibacterial activity and combined with a variety of sterilization mechanisms.Meanwhile,GO can provide richer ways of sterilization and high specific surface area,which is conducive to the grafting of quaternarized N-halamine.The advantages of physical sterilization of GO,charge adsorption of QAs,reuse of N-halamine and efficient sterilization are fully utilized.The results showed that the quaternarized N-halamine-grafted GO was obtained successfully.GO grafted with quaternarized N-halamine polymer showed strong speedy bactericidal activity against Escherichia coli(E.coli)and Staphylococcus aureus(S.aureus)(99%).It had good storage and regeneration properties. | Danlin Bu Yu Zhou Chang Yang Hengyu Feng Chunxia Cheng Mengjie Zhang Zice Xu Linghan Xiao Yujing Liu Zhenai Jin | 2021 | Chinese Chemical Letters2021，32，11： | 1 |

| 5 | Extraction of Sea-State Parameters with an X-Band Radar显示文摘Ocean wave spectrum and surface currents can be de- termined from a series of spatial wave images recorded by an X-band marine radar. In the absence of a surface current, the three-dimensional spectral energy found by using the series of images will be confined to a trajectory defined by the still water dispersion relationship. The presence of a surface current will make the three-dimensional spectral energy show a corresponding Doppler shift which may determine the current using the least squares method and obtain the directional wave spectrum. On the basis of conventional wave spectrum and directional function, the paper emulates a series of X-band radar images considering shadowing modulation and simulates numerically the three- dimensional image spectrum both with and without a surface cur- rent, calculates the current velocity by virtue of the Doppler shift, and obtains the two-dimensional image spectrum. Finally the pa- per analyzes measured wave level elevation—a function of time t to obtain one-dimensional image spectrum, and the data comes from an X-band radar in McMaster University. | WU Xiongbin WU Yanqin CHENG Feng OUYANG Wenjie KE Hengyu | 2008 | Wuhan University Journal of Natural Sciences2008，13，1： | 1 |
| 6 | YTHDF2-mediated regulations bifurcate BHPF-induced programmed cell deaths显示文摘N6-methyladenosine(m^(6)A)is a critical regulator in the fate of RNA,but whether and how m^(6)A executes its functions in different tissues remains largely obscure.Here we report downregulation of a crucial m^(6)A reader,YTHDF2,leading to tissue-specific programmed cell deaths(PCDs)upon fluorene-9-bisphenol(BHPF)exposure.Currently,Bisphenol A(BPA)substitutes are widely used in plastic manufacturing.Interrogating eight common BPA substitutes,we detected BHPF in 14%serum samples of pregnant participants.In a zebrafish model,BHPF caused tissue-specific PCDs triggering cardiac and vascular defects.Mechanistically,BHPF-mediated downregulation of YTHDF2 reduced YTHDF2-facilitated translation of m^(6)A-gch1 for cardiomyocyte ferroptosis,and decreased YTHDF2-mediated m^(6)A-sting1 decay for caudal vein plexus(CVP)apoptosis.The two distinct YTHDF2-mediated m^(6)A regulations and context-dependent co-expression patterns of gch1/ythdf2 and tnfrsf1a/ythdf2 contributed to YTHDF2-mediated tissue-specific PCDs,uncovering a new layer of PCD regulation.Since BHPF/YTHDF2-medaited PCD defects were also observed in mammals,BHPF exposure represents a potential health threat. | Jiebo Lin Guankai Zhan Jinfeng Liu Yasen Maimaitiyiming Zhiping Deng Baohua Li Kunhui Su Jiafeng Chen Siqi Sun Wanlin Zheng Xianghui Yu Feng He Xiaodong Cheng Lingfang Wang Bin Shen Ziqin Yao Xinquan Yang Jian Zhang Wentao He Hengyu Wu Hua Naranmandura Kao-Jung Chang Junxia Min Jun Ma Mikael Björklund Peng-Fei Xu Fudi Wang Chih-Hung Hsu | 2023 | National Science Review2023，10，12： | 0 |
| 7 | Crystallization and Orientation Modulation Enable Highly Efficient Doctor-Bladed Perovskite Solar Cells显示文摘With the rapid rise in perovskite solar cells(PSCs)performance,it is imperative to develop scalable fabrication techniques to accelerate potential commercialization.However,the power conversion efficiencies(PCEs)of PSCs fabricated via scalable two-step sequential deposition lag far behind the state-of-the-art spin-coated ones.Herein,the additive methylammonium chloride(MACl)is introduced to modulate the crystallization and orientation of a two-step sequential doctorbladed perovskite film in ambient conditions.MACl can significantly improve perovskite film quality and increase grain size and crystallinity,thus decreasing trap density and suppressing nonradiative recombination.Meanwhile,MACl also promotes the preferred face-up orientation of the(100)plane of perovskite film,which is more conducive to the transport and collection of carriers,thereby significantly improving the fill factor.As a result,a champion PCE of 23.14%and excellent longterm stability are achieved for PSCs based on the structure of ITO/SnO_(2)/FA_(1-x)MA_xPb(I_(1-y)Br_y)_3/Spiro-OMeTAD/Ag.The superior PCEs of 21.20%and 17.54%are achieved for 1.03 cm~2 PSC and 10.93 cm~2 mini-module,respectively.These results represent substantial progress in large-scale two-step sequential deposition of high-performance PSCs for practical applications. | Jianhui Chang Erming Feng Hengyue Li Yang Ding Caoyu Long Yuanji Gao Yingguo Yang Chenyi Yi Zijian Zheng Junliang Yang | 2023 | Nano-Micro Letters2023，15，10： | 0 |
| 8 | A hybrid CNN-LSTM model for diagnosing rice nutrient levels at the rice panicle initiation stage显示文摘Nitrogen(N)and potassium(K)are two key mineral nutrient elements involved in rice growth.Accurate diagnosis of N and K status is very important for the rational application of fertilizers at a specific rice growth stage.Therefore,we propose a hybrid model for diagnosing rice nutrient levels at the early panicle initiation stage(EPIS),which combines a convolutional neural network(CNN)with an attention mechanism and a long short-term memory network(LSTM).The model was validated on a large set of sequential images collected by an unmanned aerial vehicle(UAV)from rice canopies at different growth stages during a two-year experiment.Compared with VGG16,AlexNet,GoogleNet,DenseNet,and inceptionV3,ResNet101 combined with LSTM obtained the highest average accuracy of 83.81%on the dataset of Huanghuazhan(HHZ,an indica cultivar).When tested on the datasets of HHZ and Xiushui 134(XS134,a japonica rice variety)in 2021,the ResNet101-LSTM model enhanced with the squeeze-and-excitation(SE)block achieved the highest accuracies of 85.38 and 88.38%,respectively.Through the cross-dataset method,the average accuracies on the HHZ and XS134 datasets tested in 2022 were 81.25 and 82.50%,respectively,showing a good generalization.Our proposed model works with the dynamic information of different rice growth stages and can efficiently diagnose different rice nutrient status levels at EPIS,which are helpful for making practical decisions regarding rational fertilization treatments at the panicle initiation stage. | Fubing Liao Xiangqian Feng Ziqiu Li Danying Wang Chunmei Xu Guang Chu Hengyu Ma Qing Yao Song Chen | 2024 | Journal of Integrative Agriculture2024，23，2： | 0 |
| 9 | 26.75 cm^(2) organic solar modules demonstrate a certified efficiency of 14.34%显示文摘Organic solar cells(OSCs)have been developed rapidly in past years,due to the fast evolution of wide-bandgap copoly-mer donors and low-bandgap non-fullerene acceptors[1−9].At present,the highest power conversion efficiencies(PCEs)for single-junction OSCs and tandem OSCs exceed 19%and 20%,respectively[10,11].These OSCs are typically fabricated by us-ing low-boiling-point solvent chloroform(CF)with an effect-ive area<0.1 cm^(2).The doctor-blading deposition is the most advantageous technique to fabricate OSCs with low-boiling-point solvent for upscaling lab cells to industrial-scale mod-ules[12],exhibiting simple operation,low cost,and high materi-al utilization[13−15].Herein,a typical OSC material system PM6:Y6(Fig.1(a))was used to fabricate OSCs modules via doc-tor-blading deposition in ambient condition,and the influ-ence of the ambient temperature and substrate temperature on the film quality was investigated. | Erming Feng Yunfei Han Jianhui Chang Hengyue Li Keqing Huang Lixiu Zhang Qun Luo Jidong Zhang Changqi Ma Yingping Zou Liming Ding Junliang Yang | 2022 | Journal of Semiconductors2022，43，10： | 0 |
