| 3 | Recent advances in Pb-Sn mixed perovskite solar cells显示文摘Organic-inorganic hybrid lead-tin perovskite solar cells(Pb-Sn PSCs)have attracted much attention because of their advantages of low toxicity,variable bandgap,and feasibility for all-perovskite tandem solar cells,and the current power conversion efficiency(PCE)has exceeded 23%.However,due to the rambunctious crystallization process,easily oxidized Sn(Ⅱ)and inadequate energy level arrangement,there are many defects in perovskite films resulting in serious carrier recombination,which makes PCE still lag Pb-based PSCs.The quality of perovskite films is an important factor affecting the overall device performance.The selection and optimization of transport layers not only determines the interface energy level arrangement but also affects the carrier transport.In this paper,the research progress in improving performance of Pb-Sn PSCs in recent years is reviewed from aspects of perovskite layer and transport layers.The profound understanding of different promotion methods is summarized as well.These results have certain guiding significance for the future development and commercial application of Pb-Sn PSCs. | Yanyu Deng Guanhua Ren Danao Han Wenbin Han Zhuowei Li Chunyu Liu Wenbin Guo | 2022 | Journal of Energy Chemistry2022，31，10： | 2 |
| 4 | Efficient editing DNA regions with high sequence identity in actinomycetal genomes by a CRISPR-Cas9 system显示文摘Actinobacteria able to produce varieties of bioactive natural products have been long appreciated by the field of drug discovery and development.Recently,a few of CRISPR/Cas9 systems bearing different types of replicons(pSG5 and pIJ101)were developed to efficiently edit their genomes.Despite wide application in gene editing,their utility in editing challenging DNA regions e.g.high sequence identity has not been compared.In this study,we confirmed that the widely used temperature-sensitive pSG5 replicon is indeed not suitable for editing modular polyketide synthase(PKS)genes due to causing unpredicted gene recombination.This problem can be addressed by replacing the pSG5 with the segregationally unstable pIJ101 replicon.By introducing a counterselection marker CodA,convenient cloning sites in the single guide RNAs(sgRNAs)and homologous template scaffolds,we developed a new CRISPR-Cas9 system pMWCas9.This system was successfully used to delete/replace erythromycin PKS and other biosynthetic genes in Saccharopolyspora erythraea and Streptomyces sp.AL2110.By swapping the promoters of antB and antC with ermE and kasOp,we achieved a deacyl-antimycin hyper producer which produces a 9-fold higher yield than the original Streptomyces sp.AL2110 strain.Our results provide a robust and useful Cas9 tool for genetic studies in Actinobacteria. | Jingjun Mo Shuwen Wang Wan Zhang Chunyu Li Zixin Deng Lixin Zhang Xudong Qu | 2019 | Synthetic and Systems Biotechnology2019，4，2： | 2 |
| 5 | Residential Appliance Detection Using Attentionbased Deep Convolutional Neural Network显示文摘Improving energy efficiency management has become an important task for current electricity market participating entities,and monitoring consumption of pivotal appliances plays an important role in many applications.This paper focuses on detecting whether a residence possesses a certain type of appliance based on their electricity consumption and the problem of class imbalance within deep learning model training for large power appliances with the state‘ON’.We propose a datadriven deep learning approach with attention mechanism to detect residential appliances from low-resolution aggregate energy consumption data.Firstly,the historical consumption profile of each user is divided into a specific length and labeled with the status of an appliance to generate training and test samples.Then,a deep convolutional neural network model with attention mechanism is trained,and the trained model is utilized to classify the test samples.Meanwhile,we obtain appliance status in a residence based on classification of multiple samples.Finally,we propose a novel approach of data generation for class imbalance of appliance detection using generative adversarial networks.In order to guarantee the quality,we devise a mechanism of self-validation to ensure generated data approximating real distribution of minor class samples.Experiments are conducted on a low-frequency smart meter data set sampled once every 30 minutes,and the results show that the proposed model performs better than hidden Markov model based algorithms and has good application prospects. | Chunyu Deng Kehe Wu Binbin Wang | 2022 | CSEE Journal of Power and Energy Systems2022，8，2： | 2 |

| 7 | Controlling the morphology, size and phase of Nb_2O_5 crystals for high electrochemical performance显示文摘The morphology, size and phase of the material play a crucial role in its electrochemical performance.Herein, the nano-sized niobium pentoxide(Nb_2O_5) with different morphologies and phase structures are synthesized through a very simple thermal treatment method, including the pseudo hexagonal Nb_2O_5 nanosheets and pseudo hexagonal Nb_2O_5 nanoparticles, orthorhombic Nb_2O_5 nanoparticles. The synthesized pseudohexagonal Nb2O5 nanosheets and orthorhombic Nb_2O_5 nanoparticles exhibit better cycling and rate performance than the pseudohexagonal Nb2 O5 nanoparticles due to the different morphologies and phase structures. The T-Nb_2O_5-700 nanoparticles show the higher capacity(175 mAh/g) than that of TT-Nb_2O_5-500 nanosheets(127 mAh/g) and TT-Nb_2O_5-600 nanoparticles(39 mAh/g) at a current density of 50 mA/g and good rate performance with a capacity of 140 mAh/g at 1.0 A/g. The excellent rate capability and cycling stability of orthorhombic T-Nb_2O_5 may be ascribed to the dominant contribution of pseudocapacitive effect. This material has the great potential as a practical high-rate anode material for lithium-ion batteries. | Jiaqin Liao Rou Tan Zhixiang Kuang Chunyu Cui Zengxi Wei Xiaolan Deng Zhanheng Yan Yuezhan Feng Fang Li Caiyun Wang Jianmin Ma | 2018 | Chinese Chemical Letters2018，29，12： | 1 |
| 8 | Electrical manipulation of lightwaves in the uniaxially strained photonic honeycomb lattices under a pseudomagnetic field显示文摘The realization of pseudomagnetic fields for lightwaves has attained great attention in the field of nanophotonics.Like real magnetic fields,Landau quantization could be induced by pseudomagnetic fields in the strainengineered graphene.We demonstrated that pseudomagnetic fields can also be introduced to photonic crystals by exerting a linear parabolic deformation onto the honeycomb lattices,giving rise to degenerate energy states and flat plateaus in the photonic band structures.We successfully inspire the photonic snake modes corresponding to the helical state in the synthetic magnetic heterostructure by adopting a microdisk for the unidirectional coupling.By integrating heat electrodes,we can further electrically manipulate the photonic density of states for the uniaxially strained photonic crystal.This offers an unprecedented opportunity to obtain on-chip robust optical transports under the electrical tunable pseudomagnetic fields,opening the possibility to design Si-based functional topological photonic devices. | ZHIPENG QI HAO SUN GUOHUA HU CHUNYU DENG WANGHUA ZHU BO LIU YING LI SHAOPENG LIU XUECHAO YU YINPING CUI | 2023 | Photonics Research2023，11，7： | 0 |
| 9 | Metabolic Profiling in Banana Pseudo-Stem Reveals a Diverse Set of Bioactive Compounds with Potential Nutritional and Industrial Applications显示文摘Banana(Musa spp.)is an ancient and popular fruit plant with highly nutritious fruit.The pseudo-stem of banana represents on average 75%of the total dry mass but its valorization as a nutritional and industrial by-product is limited.Recent advances in metabolomics have paved the way to understand and evaluate the presence of diverse sets of metabolites in different plant parts.This study aimed at exploring the diversity of primary and secondary metabolites in the banana pseudo-stem.Hereby,we identified and quantified 373 metabolites from a diverse range of classes including,alkaloids,flavonoids,lipids,phenolic acids,amino acids and its derivatives,nucleotide and its derivatives,organic acids,lignans and coumarins,tannins,and terpene using the widely-targeted metabolomics approach.Banana pseudo-stem is enriched in metabolites for utilization in the food industry(L-lysine and L-tryptophan,L-glutamic acid,Phenylalanine,Palmitoleic acid,α-Linolenic acid,and Lauric acid,and Adenine)and pharmaceutical industry(Guanosine and Cimidahurinine,Bergapten,Coumarins,Procyanidin A2,Procyanidin B1,Procyanidin B3,Procyanidin B2,and Procyanidin B4,Asiatic acid).The metabolome of banana pseudo-stem with integration across multiomics data may provide the opportunity to exploit the rich metabolome of banana pseudo-stem for industrial and nutritional applications. | Guiming Deng Ou Sheng Fangcheng Bi Chunyu Li Tongxin Dou Tao Dong Qiaosong Yang Huijun Gao Jing Liu Xiaohong Zhong Miao Peng Ganjun Yi Weidi He Chunhua Hu | 2020 | Phyton-International Journal of Experimental Botany2020，89，4： | 0 |
| 10 | Overcoming Perovskite Corrosion and De-Doping Through Chemical Binding of Halogen Bonds Toward Efficient and Stable Perovskite Solar Cells显示文摘4-tert-butylpyridine(TBP)is an indispensable additive for the hole transport layer in highly efficient perovskite solar cells(PSCs),while it can induce corrosion decomposition of perovskites and de-doping effect of spiro-OMeTAD,which present huge challenge for the stability of PSCs.Herein,halogen bonds provided by 1,4-diiodotetrafluorobenzene(1,4-DITFB)are employed to bond with TBP,simultaneously preventing perovskite decomposition and eliminating de-doping effect of oxidized spiro-OMeTAD.Various characterizations have proved strong chemical interaction forms between 1,4-DITFB and TBP.With the incorporation of halogen bonds,perovskite film can maintain initial morphology,crystal structure,and light absorbance;meanwhile,the spiro-OMeTAD film shows a relatively stable conductivity with good charge transport property.Accordingly,the device with TBP complex exhibits significantly enhanced stability in N_(2) atmosphere or humidity environment.Furthermore,a champion power conversion efficiency of 23.03%is obtained since perovskite is no longer damaged by TBP during device preparation.This strategy overcomes the shortcomings of TBP in n-i-p PSCs community and enhances the application potential of spiro-OMeTAD in fabricating efficient and stable PSCs. | Guanhua Ren Wenbin Han Qiang Zhang Zhuowei Li Yanyu Deng Chunyu Liu Wenbin Guo | 2022 | Nano-Micro Letters2022，14，11： | 0 |
| 11 | A simple and visualized method to screen for effective siRNAs by using green fluorescence protein (GFP) as a reporter显示文摘To screen for effective small interference RNA(siRNA),a simple and visualized method was developed using the green fluorescence protein(GFP)as a reporter.Candidate siRNAs targeting macrophage migration inhibition factor genes(MIF)were identified.By using the pEGFP-N3 vector,the MIF-GFP expression plasmid,pEGFP-MIF,was constructed with the same Kozak consensus translation initiation site and start code ATG for the MIF-EGFP coding sequence.Based on the siRNA expression vector pSilencer-4.1,3 candidate MIF siRNA expression plasmids were constructed and co-transfected with the pEGFP-MIF into the HEK293 cells,respectively.The GFP expression in HEK293 cells could be viewed by fluorescence microscopy and the MIF mRNA expressions were determined by real-time quantitative PCR.The 3 candidate MIF siRNA expression plasmids were also co-transfected with the MIF expression plasmid into the HEK293 cells,respectively,and the MIF mRNA expressions were determined by real-time quantitative PCR.The results show that the down-regulated expression of the MIF mRNA was consistent with the GFP expression and the same effective MIF siRNAs were screened by using the pEGFP-MIF or MIF expression plasmid with the candidate MIF siRNAs expression plasmids.Therefore,by using the GFP as a reporter,a useful method was provided to screen for effective siRNAs targeting specific genes co-expressed with the GFP.This may be a good strategy for screening for effective siRNAs targeting different genes. | Zhixin SHAN Qiuxiong LIN Yongheng FU Chunyu DENG Xiaohong LI Xiyong YU | 2008 | Frontiers in Biology2008，3，4： | 0 |
| 12 | Design and synthesis of self-included pillar[5]arene-based bis-[1]rotaxanes显示文摘Two strategies for the design of new pillar[5]arene-based mechanically self-interlocked molecules (MSMs) are reported here. The first strategy is based on the construction of an intermediate pseudo[1]rotaxane followed by the desired bis-[l]rotaxane. The other one is based on the construction of the desired bis-[1]rotaxane directly via a condensation reaction through host-guest interactions between a mono-functionalized pillar[5]arene and the axle. The newly synthesized bis-[1]rotaxane BR was characterized by ~1H NMR, ^(13)C NMR, 2D NMRs (~1H-^(13)C HSQC,~1H-~1H COSY and NOESY) and LC-ESI-MS,which indicated compound BR displayed an self-interlocked structure in CDCl_3. Surprisingly, the results of SEM, TEM and DLS showed that the compound BR could assemble into spherical nanoparticles in MeOH. | Mengjun Wang Xusheng Du Huasheng Tian Qiong Jia Rong Deng Yahan Cui Chunyu Wang Kamel Meguellati | 2019 | Chinese Chemical Letters2019，30，2： | 0 |
| 13 | Hyperspectral and multispectral remote sensing image fusion using SwinGAN with joint adaptive spatial-spectral gradient loss function显示文摘Hyperspectral remote sensing image(HSI)fusion with multispectral remote sensing images(MSI)improves data resolution.However,current fusion algorithms focus on local information and overlook long-range dependencies.The parameter of network tuning prioritizes global optimization,neglecting spatial and spectral constraints,and limiting spatial and spectral reconstruction capabilities.This study introduces SwinGAN,a fusion network combining Swin Transformer,CNN,and GAN architectures.SwinGAN’s generator employs a detail injection framework to separately extract HSI and MSI features,fusing them to generate spatial residuals.These residuals are injected into the supersampled HSI to produce thefinal image,while a pure CNN architecture acts as the discriminator,enhancing the fusion quality.Additionally,we introduce a new adaptive loss function that improves image fusion accuracy.The loss function uses L1 loss as the content loss,and spatial and spectral gradient loss functions are introduced to improve the spatial representation and spectralfidelity of the fused images.Our experimental results on several datasets demonstrate that SwinGAN outperforms current popular algorithms in both spatial and spectral reconstruction capabilities.The ablation experiments also demonstrate the rationality of the various components of the proposed loss function. | Chunyu Zhu Shangqi Deng Jiaxin Li Ying Zhang Liwei Gong Liangbo Gao Na Ta Shengbo Chen Qiong Wu | 2023 | International Journal of Digital Earth2023，16，1： | 0 |
| 14 | Effects of seagrass leaf litter decomposition on sediment organic carbon composition and the key transformation processes显示文摘Seagrass leaf litters are an important source of sediment organic carbon(SOC). However, the mechanisms of seagrass leaf litter decomposition influencing SOC composition and the key transformation processes remain unknown. We performed a laboratory chamber experiment to compare the labile organic carbon(OC) composition and the enzyme activities governing SOC transformation between the seagrass group(seagrass leaf litter addition) and the control group. The results showed that the seagrass leaf litter decomposition significantly elevated the salt-extractable carbon(SEC) content and the SEC/SOC. Additionally,the levels of invertase, polyphenol oxidase, and cellulase in the seagrass leaf litters addition group were generally higher than in the control group, which could elevate recalcitrant OC decomposition. Following 24 days incubation, addition of seagrass leaf litter increased the amount of CO_2 released, but decreased the SOC content. Therefore, seagrass leaf litter decomposition leached abundant dissolved OC, which enhanced the activity and transformation of SOC. | LIU SongLin JIANG ZhiJian DENG YiQin WU YunChao ZHAO ChunYu ZHANG JingPing SHEN Yuan HUANG XiaoPing | 2017 | Science China Earth Sciences2017，60，12： | 0 |
| 15 | Structure-activity relationship of pyrazol-4-ylpyridine derivatives and identification of a radiofluorinated probe for imaging the muscarinic acetylcholine receptor M4显示文摘There is an accumulating body of evidence implicating the muscarinic acetylcholine receptor4(M4)in schizophrenia and dementia with Lewy bodies,however,a clinically validated M4positron emission tomography(PET)radioligand is currently lacking.As such,the aim of this study was to develop a suitable M4PET ligand that allows the non-invasive visualization of M4in the brain.Structure-activity relationship studies of pyrazol-4-yl-pyridine derivates led to the discovery of target compound 12—a subtype-selective positive allosteric modulator(PAM).The radiofluorinated analogue,[18F]12,was synthesized in 28±10%radiochemical yield,>37 GBq/μmol and an excellent radiochemical purity>99%.Initial in vitro autoradiograms on rodent brain sections were performed in the absence of carbachol and showed moderate specificity as well as a low selectivity of[18F]12 for the M4-rich striatum.However,in the presence of carbachol,a significant increase in tracer binding was observed in the rat striatum,which was reduced by>60%under blocking conditions,thus indicating that orthosteric ligand interaction is required for efficient binding o f[18F]12 to the allosteric site.Remarkably,however,the presence of carbachol was not required for high specific binding in the non-human primate(NHP)and human striatum,and did not further improve the specificity and selectivity of[18F]12 in higher species.These results pointed towards significant species-differences and paved the way for a preliminary PET study in NHP,where peak brain uptake of[18F]12 was found in the putamen and temporal cortex.In conclusion,we report on the identification and preclinical development of the first radiofluorinated M4PET radioligand with promising attributes.The availability of a clinically validated M4PET radioligand harbors potential to facilitate drug development and provide a useful diagnostic tool for non-invasive imaging. | Ahmed Haider Xiaoyun Deng Olivia Mastromihalis Stefanie K.Pfister Troels E.Jeppesen Zhiwei Xiao Vi Pham Shaofa Sun Jian Rong Chunyu Zhao Jiahui Chen Yinlong Li Theresa R.Connors April T.Davenport James B.Daunais Vahid Hosseini Wenqing Ran Arthur Christopoulos Lu Wang Celine Valant Steven H.Liang | 2023 | Acta Pharmaceutica Sinica B2023，13，1： | 0 |
| 16 | Sequence structure, sedimentary evolution and their controlling factors of the Jurassic Lianggaoshan Formation in the East Sichuan Basin, SW China显示文摘Based on the data of outcrops, seismic sections, thin sections, heavy mineral assemblages and detrital zircon U-Pb dating, the sedimentary characteristics, lake level fluctuation and provenance characteristics of the Middle Jurassic Lianggaoshan Formation(J_(2)l) in eastern Sichuan Basin, SW China, were investigated to reveal the control of tectonic movements of the surrounding orogenic belts on the sedimentary systems. The J_(2)lmainly developed a delta–lake sedimentary system, which contained a complete third-order sequence that was subdivided into four lake level up-down cycles(fourth-order sequence).The lake basins of cycles Ⅰ and Ⅱ were mainly distributed in eastern Sichuan Basin, while the lake basins of cycles Ⅲ and Ⅳ migrated to central Sichuan Basin, resulting in the significant difference in sedimentary characteristics between the north and the south of eastern Sichuan Basin. The provenance analysis shows that there were three types of provenances for J_(2)l. Specifically, the parent rocks of Type Ⅰ were mainly acidic igneous rocks and from the proximal northern margin of the Yangtze Plate;the parent rocks of Type Ⅱ were intermediate-acid igneous rocks and metamorphic rocks and from the central parts of the southern and northern Qinling orogenic belts;the parent rocks of Type Ⅲ were mainly metamorphic rocks followed by intermediate–acid igneous rocks, and from the North Daba Mountain area. It is recognized from the changes of sedimentary system and provenance characteristics that the sedimentary evolution of J_(2)lin eastern Sichuan Basin was controlled by the tectonic compression of the Qinling orogenic belt. In the early stage, the lake basin was restricted to the east of the study area, and Type Ⅰ provenance was dominant. With the intensifying north-south compression of the Qinling orogenic belt, the lake basin expanded rapidly and migrated northward, and the supply of Type Ⅱ provenance increased. In the middle and late stages, the uplift of the North Daba Mountain led to the lake basin migration and the gradual increase in the supply of Type Ⅲ provenance. | CHENG Dawei ZHANG Zhijie HONG Haitao ZHANG Shaomin QIN Chunyu YUAN Xuanjun ZHANG Bin ZHOU Chuanmin DENG Qingjie | 2023 | Petroleum Exploration and Development2023，50，2： | 0 |
| 17 | In-Orbit Calibration and Data Analysis of China's First Grazing Incidence Focusing X-Ray Pulsar Telescope显示文摘The grazing incidence focusing X-ray pulsar telescope(iFXPT), as the main payload of the X-ray Pulsar Navigation Test Satellite(XPNAV-1), will have great significance on China's space scientific exploration and X-ray pulsar navigation. With PSR B0531+21(Crab Pulsar) as the observation target, the pulsar profile has been recovered based on the data obtained by iFXPT, realizing the main objective of 'observing' PSR B0531+21 for the first time in China. This payload mainly consists of the Wolter-I X-ray optics, silicon drift detector, magnetic deflector, electronics, high-energy particle shield and high-stability structures. Currently, the iFXPT, with its good in-orbit performance, has obtained a considerable observation data. The effective area, sensitivity and energy response have been calibrated both on ground and in-orbit, demonstrating a high degree of consistency. Meanwhile, the in-orbit observation data and information for pulsar navigation has also been analyzed simultaneously. As a result, the feasibility of the exploration scheme and the performance of the telescope have been fully validated. | LV Zhengxin MEI Zhiwu DENG Loulou LI Liansheng SHI Yongqiang CHEN Jianwu ZUO Fuchang LIU Ke WANG Chunyu ZHANG Jianfu MO Yanan WANG Shuyan ZHAO Yuan | 2017 | Aerospace China2017，18，3： | 0 |
