2Exploring the molecular basis of heterosis for plant breeding显示文摘Since approximate a century ago, many hybrid crops have been continually developed by crossing two inbred varieties. Owing to heterosis(hybrid vigor) in plants, these hybrids often have superior agricultural performances in yield or disease resistance succeeding their inbred parental lines. Several classical hypotheses have been proposed to explain the genetic causes of heterosis. During recent years, many new genetics and genomics strategies have been developed and used for the identifications of heterotic genes in plants. Heterotic effects of the heterotic loci and molecular functions of the heterotic genes are being investigated in many plants such as rice, maize, sorghum, Arabidopsis and tomato.More and more data and knowledge coming from the molecular studies of heterotic loci and genes will serve as a valuable resource for hybrid breeding by molecular design in future. This review aims to address recent advances in our understanding of the genetic and molecular mechanisms of heterosis in plants. The remaining scientific questions on the molecular basis of heterosis and the potential applications in breeding are also proposed and discussed.Jie Liu Mengjie Li Qi Zhang Xin Wei Xuehui Huang 2020Journal of Integrative Plant Biology2020,62,3:13
3Advances in biomaterials and regenerative medicine for primary ovarian insufficiency therapy显示文摘Primary ovarian insufficiency(POI)is an ovarian dysfunction that affects more than 1%of women and is characterized by hormone imbalances that afflict women before the age of 40.The typical perimenopausal symptoms result from abnormal levels of sex hormones,especially estrogen.The most prevalent treatment is hormone replacement therapy(HRT),which can relieve symptoms and improve quality of life.However,HRT cannot restore ovarian functions,including secretion,ovulation,and fertility.Recently,as part of a developing field of regenerative medicine,stem cell therapy has been proposed for the treatment of POI.Thus,we recapitulate the literature focusing on the use of stem cells and biomaterials for POI treatment,and sum up the underlying mechanisms of action.A thorough understanding of the work already done can aid in the development of guidelines for future translational applications and clinical trials that aim to cure POI by using regenerative medicine and biomedical engineering strategies.Sichen Zhang Dashuai Zhu Xuan Mei Zhenhua Li Junlang Li Mengjie Xie Halle Jiang Williams Lutz Shaowei Wang Ke Cheng 2021Bioactive Materials2021,6,7:9
4A Simple Deep Learning Network for Classification of 3D Mobile LiDAR Point Clouds显示文摘Automatic and accurate classification is a fundamental problem to the analysis and modeling of LiDAR(Light Detection and Ranging)data.Recently,convolutional neural network(ConvNet or CNN)has achieved remarkable performance in image recognition and computer vision.While significant efforts have also been made to develop various deep networks for satellite image scene classification,it still needs to further investigate suitable deep learning network frameworks for 3D dense mobile laser scanning(MLS)data.In this paper,we present a simple deep CNN for multiple object classification based on multi-scale context representation.For the pointwise classification,we first extracted the neighboring points within spatial context and transformed them into a three-channel image for each point.Then,the classification task can be treated as the image recognition using CNN.The proposed CNN architecture adopted common convolution,maximum pooling and rectified linear unit(ReLU)layers,which combined multiple deeper network layers.After being trained and tested on approximately seven million labeled MLS points,the deep CNN model can classify accurately into nine classes.Comparing with the widely used ResNet algorithm,this model performs better precision and recall rates,and less processing time,which indicated the significant potential of deep-learning-based methods in MLS data classification.Yanjun WANG Shaochun LI Mengjie WANG Yunhao LIN 2021Journal of Geodesy and Geoinformation Science2021,4,3:8

6Stepwise-Nanocavity-Assisted Transmissive Color Filter Array Microprints显示文摘Visible-light color flters using patterned nanostructures have attracted much interest due to their various advantages such as compactness,enhanced stability,and environmental friendliness compared with traditional pigment or dye-based optical flters.While most existing studies are based on planar nanostructures with lateral variation in size,shape,and arrangement,the vertical dimension of structures is a long-ignored degree of freedom for the structural colors.Herein,we demonstrate a synthetic platform for transmissive color flter array by coordinated manipulations between height-varying nanocavities and their lateral flling fractions.Te thickness variation of those nanocavities has been fully deployed as an alternative degree of freedom,yielding vivid colors with wide gamut and excellent saturation.Experimental results show that the color-rendering capability of the pixelated nanocavities can be still retained as pixels are miniaturized to 500 nm.Crosstalk between closely spaced pixels of a Bayer color flter arrangement was calculated,showing minimal crosstalk for 1μm2 square subpixels.Our work provides an approach to designing and fabricating ultracompact color flter arrays for various potential applications including stained-glass microprints,microspectrometers,and high-resolution image sensing systems.Yasi Wang Mengjie Zheng Qifeng Ruan Yanming Zhou Yiqin Chen Peng Dai Zhengmei Yang Zihao Lin Yuxiang Long Ying Li Na Liu Cheng-Wei Qiu Joel K.W.Yang Huigao Duan 2018Research2018,,1:8
7Ultraselective carbon molecular sieve membrane for hydrogen purification显示文摘Hydrogen is a green clean fuel and chemical feedstock. Its separation and purification from hydrogencontaining mixtures is the key step in the production of hydrogen with high purity(>99.99%). In this work, carbon molecular sieve(CMS) membranes with ultrahigh permselectivity for hydrogen purification were fabricated by high-temperature(700–900 ℃) pyrolysis of polymeric precursor of phenolphthaleinbased cardo poly(arylene ether ketone)(PEK-C). The evolution of the microstructural texture and ultramicroporous structure and gas separation performance of the CMS membrane were characterized via TG-MS, FT-IR, XRD, TEM, CO2 sorption analysis and gas permeation measurements. CMS membranes prepared at 700 ℃ exhibited amorphous turbostratic carbon structures and high H2 permeability of 5260 Barrer with H2/CH4, H2/N2 and H2/CO selectivities of 311, 142, 75, respectively. When carbonized at900 ℃, the CMS membrane with ultrahigh H2/CH4 selectivity of 1859 was derived owing to the formation of the dense and ordered carbon structure. CMS membranes with ultrahigh permselectivity exhibit an attractive application prospect in hydrogen purification.Ruisong Xu Liu He Lin Li Mengjie Hou Yongzhao Wang Bingsen Zhang Changhai Liang Tonghua Wang 2020Journal of Energy Chemistry2020,29,11:8
8Single-cell Immune Landscape of Human Recurrent Miscarriage显示文摘t Successful pregnancy in placental mammals substantially depends on the establishment of maternal immune tolerance to the semi-allogenic fetus.Disorders in this process are tightly associated with adverse pregnancy outcomes including recurrent miscarriage(RM).However,an indepth understanding of the systematic and decidual immune environment in RM remains largely lacking.In this study,we utilized single-cell RNA-sequencing(scRNA-seq)to comparably analyze the cellular and molecular signatures of decidual and peripheral leukocytes in normal and unexplained RM pregnancies at the early stage of gestation.Integrative analysis identifies 22 distinct cell clusters in total,and a dramatic difference in leukocyte subsets and molecular properties in RM cases is revealed.Specifically,the cytotoxic properties of CD8^(+)effector T cells,nature killer(NK),and mucosal-associated invariant T(MAIT)cells in peripheral blood indicates apparently enhanced pro-inflammatory status,and the population proportions and ligand–receptor interactions of the decidual leukocyte subsets demonstrate preferential immune activation in RM patients.The molecular features,spatial distribution,and the developmental trajectories of five decidual NK(dNK)subsets have been elaborately illustrated.In RM patients,a dNK subset that supports embryonic growth is diminished in proportion,while the ratio of another dNK subset with cyto toxic and immune-active signature is significantly increased.Notably,a unique pro-inflammatory CD56^(+)CD16^(+)dNK subset substantially accumulates in RM decidua.These findings reveal a comprehensive cellular and molecular atlas of decidual and peripheral leukocytes in human early pregnancy and provide an in-depth insight into the immune pathogenesis for early pregnancy loss.Feiyang Wang Wentong Jia Mengjie Fan Xuan Shao Zhilang Li Yongjie Liu Yeling Ma Yu-Xia Li Rong Li Qiang Tu Yan-Ling Wang 2021Genomics, Proteomics & Bioinformatics2021,19,2:8
9Progress Towards the 90-90-90 Targets for Controlling HIV --China, 2018显示文摘What is already known about this topic?Since the Joint United Nations Programme on HIV and AIDS(UNAIDS)announced the 90-90-90 targets to control the global HIV epidemic in 2014,many countries have undertaken innovative measures to achieve this goal.The National Center for AIDS/STD Control and Prevention(NCAIDS)of China CDC convenes experts annually to evaluate the national progress towards these indicators.The most recent progress of 90-90-90 targets in China has not been previously published.What is added by this report?At the end of 2018,the percentage of living with HIV(PLWH)who had received a confirmed HIV diagnosis in China was 68.9%(61.5%-78.3%).The antiretroviral treatment coverage of diagnosed PLWH was 83.4%,and among patients on treatment for at least 12 months,94.2%achieved viral suppression.This provides most recent progress of 90-90-90 target in China.What are the implications for public health practice?China has made significant strides in curbing the HIV epidemic,but analysis on progress for the first 90 target for HIV testing remains out of reach.Innovative testing strategies may need to be developed to ensure that more PLWH can be identified.Yan Zhao Mengjie Han Ye Ma Dongmin Li 2019China CDC weekly2019,1,1:7
10Efficient hepatic delivery and protein expression enabled by optimized mRNA and ionizable lipid nanoparticle显示文摘mRNA is a novel class of therapeutic modality that holds great promise in vaccination,protein replacement therapy,cancer immunotherapy,immune cell engineering etc.However,optimization of mRNA molecules and efficient in vivo delivery are quite important but challenging for its broad application.Here we present an ionizable lipid nanoparticle(iLNP)based on iBL0713 lipid for in vitro and in vivo expression of desired proteins using codon-optimized mRNAs.mRNAs encoding luciferase or erythropoietin(EPO)were prepared by in vitro transcription and formulated with proposed iLNP,to form iLP171/mRNA formulations.It was revealed that both luciferase and EPO proteins were successfully expressed by human hepatocellular carcinoma cells and hepatocytes.The maximum amount of protein expression was found at 6 h post-administration.The expression efficiency of EPO with codon-optimized mRNA was significantly higher than that of unoptimized mRNA.Moreover,no toxicity or immunogenicity was observed for these mRNA formulations.Therefore,our study provides a useful and promising platform for mRNA therapeutic development.Tongren Yang Chunhui Li Xiaoxia Wang Deyao Zhao Mengjie Zhang Huiqing Cao Zicai Liang Haihua Xiao Xing-Jie Liang Yuhua Weng Yuanyu Huang 2020Bioactive Materials2020,5,4:7
11The IL-1R/TLR signaling pathway is essential for efficient CD8+ T-cell responses against hepatitis B virus in the hydrodynamic injection mouse model显示文摘The outcome of hepatitis B viral(HBV)infection is determined by the complex interactions between replicating HBV and the immune system.While the role of the adaptive immune system in the resolution of HBV infection has been studied extensively,the contribution of innate immune mechanisms remains to be defined.Here we examined the role of the interleukin-1 receptor/Toll-like receptor(IL-1R/TLR)signaling pathway in adaptive immune responses and viral clearance by exploring the HBV mouse model.Hydrodynamic injection with a replication-competent HBV genome was performed in wild-type mice(WT)and a panel of mouse strains lacking specific innate immunity component expression.We found higher levels of HBV protein production and replication in Tlr2^(−/−),Tlr23479^(−/−),3d/Tlr24^(−/−),Myd88/Trif^(−/−)and Irak4^(−/−)mice,which was associated with reduced HBV-specific CD8+T-cell responses in these mice.Importantly,HBV clearance was delayed for more than 2 weeks in 3d/Tlr24^(−/−),Myd88/Trif^(−/−)and Irak4^(−/−)mice compared to WT mice.HBV-specific CD8+T-cell responses were functionally impaired for producing the cytokines IFN-γ,TNF-αand IL-2 in TLR signaling-deficient mice compared to WT mice.In conclusion,the IL-1R/TLR signaling pathway might contribute to controlling HBV infection by augmenting HBV-specific CD8+T-cell responses.Zhiyong Ma Jia Liu Weimin Wu Ejuan Zhang Xiaoyong Zhang Qian Li Gennadiy Zelinskyy Jan Buer Ulf Dittmer Carsten J Kirschning Mengji Lu 2017Cellular & Molecular Immunology2017,14,12:6
12Enhanced magnetic properties in chemically inhomogeneous Nd-Dy-Fe-B sintered magnets by multi-main-phase process显示文摘Homogeneous substitution of Dy for Nd in the hard magnetic 2:14:1 phase can effectively enhance coercivity to ensure the high temperature operation,however,inevitably deteriorate remanence at expense.In this work,we performed a comparative investigation of the two magnets prepared by multimain-phase(co-sintering Nd_(2)Fe_(14)B and(Nd,Dy)_(2)Fe_(14)B powders)and single-main-phase(sintering(Nd,Dy)_(2)Fe_(14)B powders)approaches.The comparative investigation reveals that at the same Dy substitution level(2.16 wt%),such chemically inhomogeneous multi-main-phase magnet possesses better roomtemperature magnetic properties as well as thermal stability than those of the single-main-phase one with homogenous Dy distribution in the matrix grains.Room-temperature magnetic properties H_(Cj)=1664 kA/m,B_(r)=1.33 T and(BH)_(max)=350.4 kJ/m^(3)for the multi-main-phase magnet are all better than those for the single-main-phase magnet with H_(Cj)=1536 kA/m,B_(r)=1.29 T and(BH)_(max)=318.4 kj/m^(3).In addition,over the temperature range from 295 to 423 K,both the temperature coefficients of coercivity and remanence for the multi-main-phase magnet are also lower than that for the single-main-phase magnet.Such superior magnetic performance is attributed to the short-range magnetic interactions inside individual 2:14:1 phase grains and the long-range magnetostatic interactions between adjacent grains with inhomogeneous Dy distribution.Our work provides a feasible approach of enhancing coercivity and retaining energy product simultaneously in the Nd-Dy-Fe-B permanent magnets.Xiaolian Liu Mengjie Pan Pei Zhang Tianyu Ma Lizhong Zhao Lingwei Li 2021Journal of Rare Earths2021,39,5:5
13A detached petal disc assay and virus-induced gene silencing facilitate the study of Botrytis cinerea resistance in rose flowers显示文摘Fresh-cut roses(Rosa hybrida)are one of the most important ornamental crops worldwide,with annual trade in the billions of dollars.Gray mold disease caused by the pathogen Botrytis cinerea is the most serious fungal threat to cut roses,causing extensive postharvest losses.In this study,we optimized a detached petal disc assay(DPDA)for artificial B.cinerea inoculation and quantification of disease symptoms in rose petals.Furthermore,as the identification of rose genes involved in B.cinerea resistance could provide useful genetic and genomic resources,we devised a virusinduced gene silencing(VIGS)procedure for the functional analysis of B.cinerea resistance genes in rose petals.We used RhPR10.1 as a reporter of silencing efficiency and found that the rose cultivar‘Samantha’showed the greatest decrease in RhPR10.1 expression among the cultivars tested.To determine whether jasmonic acid and ethylene are required for B.cinerea resistance in rose petals,we used VIGS to silence the expression of RhLOX5 and RhEIN3(encoding a jasmonic acid biosynthesis pathway protein and an ethylene regulatory protein,respectively)and found that petal susceptibility to B.cinerea was affected.Finally,a VIGS screen of B.cinerea-induced rose transcription factors demonstrated the potential benefits of this method for the high-throughput identification of gene function in B.cinerea resistance.Collectively,our data show that the combination of the DPDA and VIGS is a reliable and highthroughput method for studying B.cinerea resistance in rose.Xiaoqian Cao Huijun Yan Xintong Liu Dandan Li Mengjie Sui Jie Wu Hongqiang Yu Zhao Zhang 2019Horticulture Research2019,6,1:5
14A novel artificial nerve graft for repairing longdistance sciatic nerve defects:a self-assembling peptide nanofiber scaffold-containing poly (lactic-co-glycolic acid) conduit显示文摘In this study, we developed a novel artificial nerve graft termed self-assembling peptide nanofiber scaffold(SAPNS)-containing poly(lactic-co-glycolic acid)(PLGA) conduit(SPC) and used it to bridge a 10-mm-long sciatic nerve defect in the rat. Retrograde tracing, behavioral testing and histomorphometric analyses showed that compared with the empty PLGA conduit implantation group, the SPC implantation group had a larger number of growing and extending axons, a markedly increased diameter of regenerated axons and a greater thickness of the myelin sheath in the conduit. Furthermore, there was an increase in the size of the neuromuscular junction and myofiber diameter in the target muscle. These findings suggest that the novel artificial SPC nerve graft can promote axonal regeneration and remyelination in the transected peripheral nerve and can be used for repairing peripheral nerve injury.Xianghai Wang Mengjie Pan Jinkun Wen Yinjuan Tang Audra D.Hamilton Yuanyuan Li Changhui Qian Zhongying Liu Wutian Wu Jiasong Guo 2014Neural Regeneration Research2014,9,24:5
15Discrimination of False Negative Results in RT-PCR Detection of SARS-CoV-2 RNAs in Clinical Specimens by Using an Internal Reference显示文摘Reverse transcription-polymerase chain reaction(RT-PCR)is an essential method for specific diagnosis of SARS-CoV-2 infection.Unfortunately,false negative test results are often reported.In this study,we attempted to determine the principal causes leading to false negative results of RT-PCR detection of SARS-CoV-2 RNAs in respiratory tract specimens.Multiple sputum and throat swab specimens from 161 confirmed COVID-19 patients were tested with a commercialfluorescent RT-PCR kit targeting the ORF1 ab and N regions of SARS-CoV-2 genome.The RNA level of a cellular housekeeping gene ribonuclease P/MRP subunit p30(RPP30)in these specimens was also assessed by RT-PCR.Data for a total of 1052 samples were retrospectively re-analyzed and a strong association between positive results in SARS-CoV-2 RNA tests and high level of RPP30 RNA in respiratory tract specimens was revealed.By using the ROC-AUC analysis,we identified Ct cutoff values for RPP30 RT-PCR which predicted false negative results for SARS-CoV-2 RT-PCR with high sensitivity(95.03%–95.26%)and specificity(83.72%–98.55%)for respective combination of specimen type and ampli-fication reaction.Using these Ct cutoff values,false negative results could be reliably identified.Therefore,the presence of cellular materials,likely infected host cells,are essential for correct SARS-CoV-2 RNA detection by RT-PCR in patient specimens.RPP30 could serve as an indicator for cellular content,or a surrogate indicator for specimen quality.In addition,our results demonstrated that false negativity accounted for a vast majority of contradicting results in SARS-CoV-2 RNA test by RT-PCR.Yafei Zhang Changtai Wang Mingfeng Han Jun Ye Yong Gao Zhongping Liu Tengfei He Tuantuan Li Mengyuan Xu Luping Zhou Guizhou Zou Mengji Lu Zhenhua Zhang 2020Virologica Sinica2020,35,6:5
16MOF-derived ZnCo_2O_4/C wrapped on carbon fiber as anode materials for structural lithium-ion batteries显示文摘To meet the requirements for the mechanical and electrochemical performance for carbon fiber-based (CF-based) composites in the structural lithium ion batteries (SLIBs) application, better CF-Based composites are urgently needed. Herein, we report a novel composite metal organic framework (MOF)-derived ZnCo_2 O_4/C@carbon fiber via a facile method and subsequent annealing treatment. In this anode,the nano ZnCo_2 O_4/C coatings wrapped on the surface of CF provide more active sites for electrode reactions and the thin carbon layers give the additional protection. For this material, after 100 cycles, it exhibits excellent cycling stability including high reversible capacity of 463 mAh/g at 50 mA/g, which increases 201% than that of the CF. Thus, this structural anode material exhibits enhanced capacity, high initial columbic efficiency.Huagen Li Shubin Wang Mengjie Feng Jiping Yang Boming Zhang 2019Chinese Chemical Letters2019,30,2:4
17The histone methyltransferase EZH2 primes the early differentiation of follicular helper T cells during acute viral infection显示文摘Epigenetic modifications to histones dictate the differentiation of naïve CD4^(+) T cells into different subsets of effector T helper(TH)cells.The histone methyltransferase enhancer of zeste homolog 2(EZH2)has been implicated in the mechanism regulating the differentiation of TH1,TH2 and regulatory T(Treg)cells.However,whether and how EZH2 regulates follicular helper T(TFH)cell differentiation remain unknown.Using a mouse model of acute lymphocytic choriomeningitis virus(LCMV)infection,we observed abundant EZH2 expression and associated H3K27me3 modifications preferentially in the early committed virus-specific TFH cells compared to those in TH1 cells.Ablation of EZH2 in LCMV-specific CD4^(+) T cells leads to a selective impairment of early TFH cell fate commitment,but not late TFH differentiation or memory TFH maintenance.Mechanistically,EZH2 specifically stabilizes the chromatin accessibility of a cluster of genes that are important for TFH fate commitment,particularly B cell lymphoma 6(Bcl6),and thus directs TFH cell commitment.Therefore,we identified the chromatin-modifying enzyme EZH2 as a novel regulator of early TFH differentiation during acute viral infection.Xiangyu Chen Guoshuai Cao Jialin Wu Xinxin Wang Zhiwei Pan Jianbao Gao Qin Tian Lifan Xu Zhirong Li Yaxing Hao Qizhao Huang Pengcheng Wang Minglu Xiao Luoyingzi Xie Shupei Tang Zhenyu Liu Li Hu Jianfang Tang Ran He Li Wang Xinyuan Zhou Yuzhang Wu Mengjie Chen Beicheng Sun Bo Zhu Jun Huang Lilin Ye 2020Cellular & Molecular Immunology2020,17,3:4
18Methylation of RAR-β2, RASSF1A, and CDKN2A Genes Induced by Nickel Subsulfide and Nickel-carcinogenesis in Rats显示文摘Objective To investigate the expression variation of RAR‐β2, RASSF1A, and CDKN2A gene in the process of nickel‐induced carcinogenesis. Methods Nickel subsulfide (Ni 3 S 2 ) at dose of 10 mg was given to Wistar rats by intramuscular injection. The mRNA expression of the three genes in induced tumors and their lung metastasis were examined by Real‐time PCR. The methylation status of the 5' region of these genes were detected by Quantitative Real‐time methylation specific PCR. Results The mRNA expressions of the three genes both in muscle and lung tumor were decreased distinctly in comparison with normal tissue. But hypermethylation was found only in muscle tumor. Conclusion These findings suggest that loss of function or decrease of RAR‐β2, RASSF1A, and CDKN2A, as well as the hypermethylation of 5' region of these genes, are related with nickel exposure.ZHANG Jun ZHANG Jing LI MengJie Wu YouJun FAN YingYing ZHOU Yang TAN LiLi SHAO ZhiHua SHI HongJun 2011Biomedical and Environmental Sciences2011,24,2:4
19Complementation of Wild-Type and Drug-Resistant Hepatitis B Virus Genomes to Maintain Viral Replication and Rescue Virion Production under Nucleos(t)ide Analogs显示文摘As the open reading frames of hepatitis B virus(HBV)genomes are overlapping,resistance mutations(MTs)in HBV polymerase may result in stop codon MTs in hepatitis B surface proteins,which are usually detected as a mixed population with wild-type(WT)HBV.The question was raised how the coexistence of nucleos(t)ide analogs(NAs)resistance MTs and WT sequences affects HBV replication.In the present study,HBV genomes with frequently detected reverse transcriptase(RT)/surface truncation MTs,rtA181T/sW172^*,rtV191I/sW182^*and rtM204I/sW196^*,were phenotypically characterized alone or together with their WT counterparts in different ratios by transient transfection in the absence or presence of Nas.In the absence of Nas,RT/surface truncation MTs impaired the expression and secretion of HBV surface proteins,and had a dose-dependent negative effect on WT HBV virion secretion.However,in the presence of Nas,coexistence of MTs with WT maintained viral replication,and the presence of WT was able to rescue the production of MT HBV virions.Our findings reveal that complementation of WT and MT HBV genomes is highly effective under drug treatment.Chunchen Wu Baolin Li Xiaoyong Zhang Kaitao Zhao Yingshan Chen Yifei Yuan Yan Liu Rongjuan Chen Dongping Xu Xinwen Chen Mengji Lu 2019Virologica Sinica2019,34,4:4
20Solvent engineering towards scalable fabrication of high-quality perovskite films for efficient solar modules显示文摘Over the last decade,remarkable progress has been made in metal halide perovskite solar cells(PSCs),which have been a focus of emerging photovoltaic techniques and show great potential for commercialization.However,the upscaling of small-area PSCs to large-area solar modules to meet the demands of practical applications remains a significant challenge.The scalable production of high-quality perovskite films by a simple,reproducible process is crucial for resolving this issue.Furthermore,the crystallization behavior in the solution-processed fabrication of perovskite films can be strongly influenced by the physicochemical properties of the precursor inks,which are significantly affected by the employed solvents and their interactions with the solutes.Thus,a comprehensive understanding of solvent engineering for fabricating perovskite films over large areas is urgently required.In this paper,we first analyze the role of solvents in the solution-processed fabrication of large-area perovskite films based on the classical crystal nucleation and growth mechanism.Recent efforts in solvent engineering to improve the quality of perovskite films for solar modules are discussed.Finally,the basic principles and future challenges of solvent system design for scalable fabrication of high-quality perovskite films for efficient solar modules are proposed.Zhaoyi Jiang Binkai Wang Wenjun Zhang Zhichun Yang Mengjie Li Fumeng Ren Tahir Imran Zhenxing Sun Shasha Zhang Yiqiang Zhang Zhiguo Zhao Zonghao Liu Wei Chen 2023Journal of Energy Chemistry2023,,5:4
