| 1 | Molecular crowding agents engineered to make bioinspired electrolytes for high-voltage aqueous supercapacitors显示文摘The development of low-cost and eco-friendly aqueous electrolytes with a wide voltage window is the key to achieving safe high energy density supercapacitors(SCs).In this work,a molecular crowding electrolyte is prepared by simulating the crowded environment in living cells.Ion transport in the molecular crowding electrolyte can be effectively improved via reducing the molecular weight of the crowding agent,polyethylene glycol(PEG).The results show that PEG with a molecular weight of 200(PEG200)can significantly improve ionic conductivity while maintaining a wide voltage window.These advantages enable commercial activated carbon-based SCs to work at 2.5 V with high energy density,outstanding rate performance and good stability for more than 10,000 cycles.On this basis,three series of molecular crowding electrolytes using sodium perchlorate,lithium perchlorate,and sodium trifluoromethanesulfonate as salts are developed,demonstrating the versatility of PEG200 for wide-voltage aqueous electrolytes. | Mengke Peng Li Wang Longbin Li Zhongyou Peng Xiannong Tang Ting Hu Kai Yuan Yiwang Chen | 2021 | eScience2021，1，1： | 5 |
| 2 | Reducing Energy Loss and Morphology Optimization Manipulated by Molecular Geometry Engineering for Hetero-junction Organic Solar Cells显示文摘of main observation and conclusion Molecular geometry engineering is an efective strategy to control the micromorphology and molecularenergy level in organic photovoltaics(OPVs).Two novel copolymers based on alkysilyl-and chloride-functionalied benzodithiophene(BDT)were designed and synthesized for wide bandgap copolymer donor materials in OPVs.It was found that the two copolymers exhited distinctly different proper-ties in active layer when blended with fulerene-fre acceptor T-4.The chloride-functionalited copolymer PBDTCI-TZ2 with deeper molecular energy leveland better coplanar structure induced more ordered aggregation in blend flm.Thus,the device based on PBDTC-TZ exhibits better energy alinmentwith IT-4F and smallr radiative recombination.furthermore,the non-radiative recombination of PBDTCI-TZ.T-4F based device is about 45 mV lowerthan the PBDTS-TZ/T-4F based device,contributing to a lower enery loss(Ein,and a higher open-cicut voltage(Vc).As a resut,the devices based onthe blend of PBDTC-TZ2.IT-4F exhibit a high power conversion efficiency(PCE)of up to 12.2%with a high Vvoe of 0.837 Vv,higher than that of PBDTSi-TZ:IT-4F,of which the PCE is 11.2%with a Voc of 0.781V. | Guodong Xu Huan Rao Xunfan Liao Youdi Zhang Yuming Wang Zhi Xing Ting Hu Licheng Tan Lie Chen Yiwang Chen | 2020 | Chinese Journal of Chemistry2020，38，12： | 4 |
| 3 | Wide Band-gap Two-dimension Conjugated Polymer Donors with Different Amounts of Chlorine Substitution on Alkoxyphenyl Conjugated Side Chains for Non-fullerene Polymer Solar Cells显示文摘In this study,wide bandgap(WBG)two-dimensional(2D)copolymer donors(DZ1,DZ2,and DZ3)based on benzodithiophene(BDT)on alkoxyphenyl conjugated side chains without and with different amounts of chlorine atoms and difluorobenzotriazole(FBTZ)are designed and synthesized successfully for efficient non-fullerene polymer solar cells(PSCs).Three polymer donors DZ1,DZ2,and DZ3 display similar absorption spectra at 300-700 nm range with optional band-gap(Egopt)of 1.84,1.92,and 1.97 eV,respectively.Compared with reported DZ1 without chlorine substitution,it is found that introducing chlorine atoms into the meta-position of the alkoxyphenyl group affords polymer possessing a deeper the highest occupied molecular orbital(HOMO)energy level,which can increase open circuit voltage(Voc)of PSCs,as well as improve hole mobility.Non-fullerene bulk heterojunction PSCs based on DZ2:MelC demonstrate a relatively high power conversion efficiency(PCE)of 10.22%with a Voc of 0.88 V,a short-circuit current density(Jsc)of 17.62 mA/cm^2,and a fill factor(FF)of 68%,compared with PSCs based on DZ1:MelC(a PCE of 8.26%)and DZ3:MelC(a PCE of 6.28%).The results imply that adjusting chlorine atom amount on alkoxyphenyl side chains based on BDT polymer donors is a promising approach of synthesizing electron-rich building block for high performance of PSCs. | Youdi Zhang Yong Wang Ruijie Ma Zhenghui Luo Tao Liu So-Huei Kang He Yan Zhongyi Yuan Changduk Yang Yiwang Chen | 2020 | Chinese Journal of Polymer Science2020，38，8： | 3 |
| 4 | A key‘foxy’aroma gene is regulated by homologyinduced promoter indels in the iconic juice grape‘Concord’显示文摘‘Concord’,the most well-known juice grape with a parentage of the North American grape species Vitis labrusca L.,possesses a special‘foxy’aroma predominantly resulted from the accumulation of methyl anthranilate(MA)in berries.This aroma,however,is often perceived as an undesirable attribute by wine consumers and rarely noticeable in the common table and wine grape species V.vinifera.Here we discovered homology-induced promoter indels as a major genetic mechanism for species-specific regulation of a key‘foxy’aroma gene,anthraniloyl-CoA:methanol acyltransferase(AMAT),that is responsible for MA biosynthesis.We found the absence of a 426-bp and/or a 42-bp sequence in AMAT promoters highly associated with high levels of AMAT expression and MA accumulation in‘Concord’and other V.labrusca-derived grapes.These promoter variants,all with direct and inverted repeats,were further confirmed in more than 1,300 Vitis germplasm.Moreover,functional impact of these indels was validated in transgenic Arabidopsis.Superimposed on the promoter regulation,large structural changes including exonic insertion of a retrotransposon were present at the AMAT locus in some V.vinifera grapes.Elucidation of the AMAT genetic regulation advances our understanding of the‘foxy’aroma trait and makes it genetically trackable and amenable in grapevine breeding. | Yingzhen Yang JoséCuenca Nian Wang Zhenchang Liang Honghe Sun Benjamin Gutierrez Xiaojun Xi Jie Arro YiWang Peige Fan Jason Londo Peter Cousins Shaohua Li Zhangjun Fei Gan-Yuan Zhong | 2020 | Horticulture Research2020，7，1： | 3 |
| 5 | Highly stable Al-doped ZnO by ligand-free synthesis as general thickness-insensitive interlayers for organic solar cells显示文摘Highly conductive and dispersible Al-doped ZnO(AZO) nanoparticles(NPs) have been successfully prepared by ligand-free colloidal synthesis at low temperature and stabilization by surfactant-aid including ethanolamine(EA), ethylenediamine(EDA),diethylenetriamine(DETA) and triethylenetetramine(TETA). Due to the strong intermolecular hydrogen-bonding interactions between AZO NPs and the amino groups from surfactants, the inevitable aggregation was suppressed and the surface defect sites were passivated obviously. The existence of electron transfer from the nitrogen of the amino groups to the zinc of AZO,led to a dramatic increase in electrical conductivity. A homogeneous current intensity value up to ~2200 pA for AZO tread by DETA was characterized by conductive atomic force microscopy(C-AFM), which was more superior than that of the reported sol-gel synthesized AZO with the assistance of EA surfactant(refer to 170.7 pA). Furthermore, non-fullerenes solar cells based on PBDB-T:ITIC with AZO-DETA(80 nm) yielded a best device efficiency of 10.7% and kept up prominent PCE exceeding 10%even with more thicker interlayer(95 nm). | Yilin Wang Zhongyou Peng Shuqin Xiao Jia Yang Huanyu Zhou Liqiang Huang Lulu Sun Yinhua Zhou Licheng Tan Yiwang Chen | 2018 | Science China Chemistry2018，61，1： | 2 |
| 6 | A non-wetting and conductive polyethylene dioxothiophene hole transport layer for scalable and flexible perovskite solar cells显示文摘The regulated crystallization of perovskite and highly repeatable preparation are decisive challenges for large-scale flexible perovskite solar cells(PSCs).Herein,we synthesize an oil-soluble poly(3,4-ethylenedioxythiophene)(Oil-PEDOT)as a hole transport layer(HTL).The non-wetting Oil-PEDOT HTL can promote the quality of large-area flexible perovskite films because of its optimized crystallinity and printability.The Oil-PEDOT layer also delivers desirable conductivity and charge transport without a complex doping.Consequently,the flexible PSCs with Oil-PEDOT HTL achieve an efficiency of 19.51%and 16.70%based on 1.05 and 22.50 cm^(2),respectively.Moreover,these large-scale flexible PSCs demonstrate remarkable mechanical robustness,and the efficiency exhibits 93%retention after 7,000 bending cycles.These results show that the Oil-PEDOT is a potentially efficient HTL for fabricating efficient large-scale flexible PSCs. | Chenxiang Gong Lin Zhang Xiangchuan Meng Zhi Xing Li Rao Hongyu Wang Zengqi Huang Licheng Tan Ting Hu Xiaotian Hu Yiwang Chen | 2021 | Science China Chemistry2021，64，5： | 1 |

| 8 | Highly crystalline acceptor materials based on benzodithiophene with different amount of fluorine substitution on alkoxyphenyl conjugated side chains for organic photovoltaics显示文摘Organic solar cells based on narrow bandgap small-molecule acceptors(SMAs)with highly crystalline characteristics have attracted great attentions for their superiority in obtaining high photovoltaic efficiency.Employing highly crystalline SMAs to enhance power conversion efficiencies(PCEs)by regulating and controlling morphology and compatibility of donor and acceptor materials has turned out to be an effective approach.In this study,we synthesized three different crystalline SMAs by using fluorine substitution on alkoxyphenyl conjugated side chains to modulate the relationship of crystallinity and morphologies,namely ZY1(zero F atoms),ZY2(two F atoms),and ZY3(four F atoms).The three SMAs show the broad absorption edges and similar frontier orbital energy levels,generating the analogical(over 0.9 V)open circuit voltage(VOC)of the polymer solar cells(PSCs).As a result,the PM6:ZY2-based PSCs yield a PCE of 10.81%with a VOC of 0.95 V,a short-circuit current density(JSC)of 16.154 mA cm^(-2),and a fill factor(FF)of 0.71,which is higher than that of 9.17%(PM6:ZY1)and 6.37%(PM6:ZY3).And the PCE(17.23%)of the PM6:Y6:ZY2 based ternary PSCs is also higher than that of 16.32%PM6:Y6 based binary device.Obviously,the results demonstrate that adding fluorine atoms on the conjugated side chains to construct high crystalline materials is a positive strategy to effectively increase the efficiencies of binary and ternary PSCs. | Youdi Zhang Ruijie Ma Yong Wang Ying Wang Tao Liu Yiqun Xiao Yongjoon Cho Zhenghui Luo Xinhui Lu Lun Zhao Zhongyi Yuan Changduk Yang He Yan Yiwang Chen | 2021 | Materials Reports(Energy)2021，1，4： | 1 |

| 10 | Concerted regulation on vertical orientation and film quality of two-dimensional ruddlesden-popper perovskite layer for efficient solar cells显示文摘Recently,the two-dimensional(2D)ruddlesden-popper(RPP)perovskite has been successfully attracting great attention owing to their excellent electronic property and superior ambient stability.But 2D perovskite solar cells(PVSCs)with insulating large cations show a worse performance than three-dimensional(3D)PVSCs in general because of the worse charge transportation.In this work,dimethyl sulfoxide(DMSO)and KI were incorporated simultaneously to produce a synergistic effect on both film quality and orientation of 2D perovskite.With this strategy,a cavity-free 2D perovskite film was formed with vertically oriented crystal,and high quality film was obtained with decreased defects and increased crystallinity.Besides,profitable multiple phases were obtained for better spontaneous carrier separation and transportation.The 2D PVSCs based on(PEA)2(MA)n−1PbnI3n+1(n=5)delivered a higher power conversion efficiency(PCE)of 13.4%.In addition,the perovskite with KI and DMSO contained more stable low-dimension phase at the bottom of perovskite film,which could act as a barrier to prevent moisture from further eroding internal perovskites.The optimized 2D PVSCs remained 90%of the PCE after being exposed in air(50%–60%humidity,room temperature)with a continuous illumination for 300 h. | Xianglan Tang Xueying Wang Ting Hu Qingxia Fu Xiaotian Hu Zengqi Huang Shuqin Xiao Yiwang Chen | 2020 | Science China Chemistry2020，63，11： | 1 |

| 16 | Genome-scale metabolic models applied for human health and biopharmaceutical engineering显示文摘Over the last 15 years,genome-scale metabolic models(GEMs)have been reconstructed for human and model animals,such as mouse and rat,to systematically understand metabolism,simulate multicellular or multi-tissue interplay,understand human diseases,and guide cell factory design for biopharmaceutical protein production.Here,we describe how metabolic networks can be represented using stoichiometric matrices and well-defined constraints for flux simulation.Then,we review the history of GEM development for quantitative understanding of Homo sapiens and other relevant animals,together with their applications.We describe how model develops from H.sapiens to other animals and from generic purpose to precise context-specific simulation.The progress of GEMs for animals greatly expand our systematic understanding of metabolism in human and related animals.We discuss the difficulties and present perspectives on the GEM development and the quest to integrate more biological processes and omics data for future research and translation.We truly hope that this review can inspire new models developed for other mammalian organisms and generate new algorithms for integrating big data to conduct more in-depth analysis to further make progress on human health and biopharmaceutical engineering. | Feiran Li Yu Chen Johan Gustafsson Hao Wang YiWang Chong Zhang Xinhui Xing | 2023 | Quantitative Biology2023，11，4： | 0 |

| 18 | Identification of natural allelic variation in TTL1 controlling thermotolerance and grain size by a rice super pan-genome∞显示文摘Continuously increasing global temperatures present great challenges to food security.Grain size,one of the critical components determining grain yield in rice(Oryza sativa L.),is a prime target for genetic breeding.Thus,there is an immediate need for genetic improvement in rice to maintain grain yield under heat stress.However,quantitative trait loci(QTLs)endowing heat stress tolerance and grain size in rice are extremely rare.Here,we identified a novel negative regulator with pleiotropic effects,Thermo‐Tolerance and grain Length 1(TTL1),from the super pan‐genomic and transcriptomic data.Loss‐of‐function mutations in TTL1 enhanced heat tolerance,and caused an increase in grain size by coordinating cell expansion and proliferation.TTL1 was shown to function as a transcriptional regulator and localized to the nucleus and cell membrane.Furthermore,haplotype analysis showed that hapL and hapS of TTL1 were obviously correlated with variations of thermotolerance and grain size in a core collection of cultivars.Genome evolution analysis of available rice germplasms suggested that TTL1 was selected during domestication of the indica and japonica rice subspecies,but still had much breeding potential for increasing grain length and thermotolerance.These findings provide insights into TTL1 as a novel potential target for the development of high‐yield and thermotolerant rice varieties. | Yarong Lin Yiwang Zhu Yuchao Cui Hongge Qian Qiaoling Yuan Rui Chen Yan Lin Jianmin Chen Xishi Zhou Chuanlin Shi Huiying He Taijiao Hu Chenbo Gu Xiaoman Yu Xiying Zhu Yuexing Wang Qian Qian Cuijun Zhang Feng Wang Lianguang Shang | 2023 | Journal of Integrative Plant Biology2023，65，12： | 0 |
| 19 | Exact Vibration Solutions of Nonhomogeneous Circular,Annular and Sector Membranes显示文摘In this paper,exact vibration frequencies of circular,annular and sector membranes with a radial power law density are presented for the first time.It is found that in general,the sequence of modes may not correspond to increasing azimuthal mode number n.The normalized frequency increases with the absolute value of the power index|n|.For a circular membrane,the fundamental frequency occurs at n=0 where n is the number of nodal diameters.For an annular membrane,the frequency increases with respect to the inner radius b.When b is close to one,the width 1−b is the dominant factor and the differences in frequencies are small.For a sector membrane,n−1 is the number of internal radial nodes and the fundamental frequency occurs at n=1.Increased opening angle b increases the frequency. | Chang YiWang Wang Chien Ming | 2012 | Advances in Applied Mathematics and Mechanics2012，4，2： | 0 |
| 20 | A domesticated Harbinger transposase forms a complex with HDA6 and promotes histone H3 deacetylation at genes but not TEs in Arabidopsis显示文摘In eukaryotes,histone acetylation is a major modification on histone N-terminal tails that is tightly connected to transcriptional activation.HDA6 is a histone deacetylase involved in the transcriptional regulation of genes and transposable elements(TEs)in Arabidopsis thaliana.HDA6 has been shown to participate in several complexes in plants,including a conserved SIN3 complex.Here,we uncover a novel protein complex containing HDA6,several Harbinger transposon-derived proteins(HHP1,SANT1,SANT2,SANT3,and SANT4),and MBD domain-containing proteins(MBD1,MBD2,and MBD4).We show that mutations of all four SANT genes in the sant-null mutant cause increased expression of the flowering repressors FLC,MAF4,and MAF5,resulting in a late flowering phenotype.Transcriptome deep sequencing reveals that while the SANT proteins and HDA6 regulate the expression of largely overlapping sets of genes,TE silencing is unaffected in sant-null mutants.Our global histone H3 acetylation profiling shows that SANT proteins and HDA6 modulate gene expression through deacetylation.Collectively,our findings suggest that Harbinger transposon-derived SANT domain-containing proteins are required for histone deacetylation and flowering time control in plants. | Xishi Zhou Junna He Christos N.Velanis Yiwang Zhu Yuhan He Kai Tang Mingku Zhu Lisa Graser Erica de Leau Xingang Wang Lingrui Zhang W.Andy Tao Justin Goodrich Jian-Kang Zhu Cui-Jun Zhang | 2021 | Journal of Integrative Plant Biology2021，63，8： | 0 |
