| 1 | Organic photovoltaic cell with 17% efficiency and superior processability显示文摘The development of organic photoactive materials,especially the newly emerging non-fullerene electron acceptors(NFAs),has enabled rapid progress in organic photovoltaic(OPV)cells in recent years.Although the power conversion efficiencies(PCEs)of the top-performance OPV cells have surpassed 16%,the devices are usually fabricated via a spin-coating method and are not suitable for large-area production.Here,we demonstrate that the fine-modification of the flexible side chains of NFAs can yield 17%PCE for OPV cells.More crucially,as the optimal NFA has a suitable solubility and thus a desirable morphology,the high efficiencies of spin-coated devices can be maintained when using scalable blade-coating processing technology.Our results suggest that optimization of the chemical structures of the OPV materials can improve device performance.This has great significance in larger-area production technologies that provide important scientific insights for the commercialization of OPV cells. | Yong Cui Huifeng Yao Ling Hong Tao Zhang Yabing Tang Baojun Lin Kaihu Xian Bowei Gao Cunbin An Pengqing Bi Wei Ma Jianhui Hou | 2020 | National Science Review2020，7，7： | 7 |
| 2 | Family-level leaf nitrogen and phosphorus stoichiometry of global terrestrial plants显示文摘Leaf nitrogen(N) and phosphorus(P) concentrations are critical for photosynthesis, growth, reproduction and other ecological processes of plants. Previous studies on large-scale biogeographic patterns of leaf N and P stoichiometric relationships were mostly conducted using data pooled across taxa, while family/genus-level analyses are rarely reported. Here, we examined global patterns of family-specific leaf N and P stoichiometry using a global data set of 12,716 paired leaf N and P records which includes 204 families, 1,305 genera, and 3,420 species. After determining the minimum size of samples(i.e., 35 records), we analyzed leaf N and P concentrations, N:P ratios and N^P scaling relationships of plants for 62 families with 11,440 records. The numeric values of leaf N and P stoichiometry varied significantly across families and showed diverse trends along gradients of mean annual temperature(MAT) and mean annual precipitation(MAP). The leaf N and P concentrations and N:P ratios of 62 families ranged from 6.11 to 30.30 mg g–1, 0.27 to 2.17 mg g–1, and 10.20 to 35.40, respectively. Approximately 1/3–1/2 of the families(22–35 of 62) showed a decrease in leaf N and P concentrations and N:P ratios with increasing MAT or MAP, while the remainder either did not show a significant trend or presented the opposite pattern. Family-specific leaf N^P scaling exponents did not converge to a certain empirical value, with a range of 0.307–0.991 for 54 out of 62 families which indicated a significant N^P scaling relationship. Our results for the first time revealed large variation in the family-level leaf N and P stoichiometry of global terrestrial plants and that the stoichiometric relationships for at least one-third of the families were not consistent with the global trends reported previously. The numeric values of the family-specific leaf N and P stoichiometry documented in the current study provide critical synthetic parameters for biogeographic modeling and for further studies on the physiological and ecological mechanisms underlying the nutrient use strategies of plants from different phylogenetic taxa. | Di Tian Zhengbing Yan Suhui Ma Yuehong Ding Yongkai Luo Yahan Chen Enzai Du Wenxuan Han Emoke Dalma Kovacs Haihua Shen Huifeng Hu Jens Kattge Bernhard Schmid Jingyun Fang | 2019 | Science China(Life Sciences)2019，62，8： | 7 |

| 4 | Chromosome-level genome of Himalayan yew provides insights into the origin and evolution of the paclitaxel biosynthetic pathway显示文摘Taxus,commonly known as yew,is a well-known gymnosperm with great ornamental and medicinal value.In this study,by assembling a chromosome-level genome of the Himalayan yew(Taxus wallichiana)with 10.9 Gb in 12 chromosomes,we revealed that tandem duplication acts as the driving force of gene family evolution in the yew genome,resulting in the main genes for paclitaxel biosynthesis,i.e.those encoding the taxadiene synthase,P450s,and transferases,being clustered on the same chromosome.The tandem duplication may also provide genetic resources for the nature to sculpt the core structure of taxoids at different positions and subsequently establish the complex pathway of paclitaxel by neofunctionalization.Furthermore,we confirmed that there are two genes in the cluster encoding isoenzymes of a known enzyme in the paclitaxel biosynthetic pathway.The reference genome of the Himalayan yew will serve as a platform for decoding the complete biosynthetic pathway of paclitaxel and understanding the chemodi-versity of taxoids in gymnosperms. | Jian Cheng Xiao Wang Xiaonan Liu Xiaoxi Zhu Zihe Li Huanyu Chu Qian Wang QianQian Lou Bijun Cai Yiqun Yang Xiaoyun Lu Kai Peng Dingyu Liu Yuwan Liu Lina Lu Huan Liu Ting Yang Qijin Ge Chengcheng Shi Guichun Liu Zhiwei Dong Xun Xu Wen Wang Huifeng Jiang Yanhe Ma | 2021 | Molecular Plant2021，14，7： | 6 |
| 5 | Magnetic beads-based multicolor colorimetric immunoassay for ultrasensitive detection of aflatoxin B_(1)显示文摘Aflatoxin B_(1)(AFB_(1))is one of the most toxic,mutagenic and carcinogenic mycotoxin,widely exists in contaminated food,grains and feedstuff products.In this study,a novel magnetic beads multicolor colorimetric immunoassay(MBMCIA)based on Au@Ag nanorods(Au@Ag NRs)is proposed to visual detect ultralow concentration of AFB_(1)with high-resolution by the naked-eye.To design the MBMCIA system,AFB_(1)-BSA conjugates were first coated on the surface of magnetic beads(MBs),then alkaline phosphatase(ALP)as a bridge between immunoassay a nd color reaction was used for catalytic hydrolysis of ascorbic acid-phosphate to generate reductive ascorbic acid.Finally,the yielded ascorbic acid could reduce silver ions to grow a silver coating on the surface of gold nanorods to generate Au@Ag NRs,which leads to the bule-shifted longitudinal absorption peak of Au NRs,accompanying with a series of perceptible color change.Under the optimal conditions,the proposed MBMCIA exhibited go od sensitivity and specificity for the detection of AFB_(1)with the detection limit as low as 5.7 pg/mL Meanwhile,the MBMCIA was also applied for the analysis of AFB_(1)in spiked wheat samples,the obtained recoveries range from 99.1%to 104.3%with relative standard deviation(RSD)less than 7.05%were acceptable.The proposed MBMCIA integrates separated,enriched,anti-interfe rence and signal read-out into one,which opens up a new avenue for an on-site visual food safety inspection or environmental monitoring. | Shan He Qitong Huang Ying Zhang Huifang Zhang Huifeng Xu Xun Li Xiaoming Ma | 2021 | Chinese Chemical Letters2021，32，4： | 3 |
| 6 | Three-dimensional large-aperture lens antennas with gradient refractive index显示文摘We propose an accurate method for designing three-dimensional(3D)large-aperture metamaterial slab lens antennas with gradient refractive index(GRIN).According to the geometric optics,Fermat principle,ray-tracing technique and impedance matching,the 3D GRIN slab lenses with large apertures are accurately designed and simulated.With the aid of the efective medium theory,an X-band and a Ku-band conical horn antennas loaded with the 3D GRIN slab lenses of 250-mm diameter are experimentally realized using the drilling-hole technique on the printed circuit boards(PCBs)as the unit cells of metamaterials.Compared to the traditional dielectric lens with the same aperture,the proposed antennas have very good performance with high directivity,and the gain is increased by 2 to 5 dB.Using the same method,we design and realize a huge-aperture GRIN lens in the X band with a diameter of 1000 mm,which is composed of nearly one millions of inhomogeneous unit cells of square-ring resonators and dielectric blocks with drilling holes.Due to the huge aperture size,the electromagnetic ray paths inside and outside of the GRIN lens are verifed and optimized using the ray tracing technique.Measurement results show good performance of the proposed antenna with high directivity. | ZHOU XiaoYang ZOU XiaYing YANG Yan MA HuiFeng CUI TieJun | 2013 | Science China(Information Sciences)2013，56，12： | 3 |
| 7 | The origin and evolution of the diosgenin biosynthetic pathway in yam显示文摘Diosgenin,mainly produced by Dioscorea species,is a traditional precursor of most hormonal drugs in the pharmaceutical industry.The mechanisms that underlie the origin and evolution of diosgenin biosynthesis in plants remain unclear.After sequencing the whole genome of Dioscorea zingiberensis,we revealed the evolutionary trajectory of the diosgenin biosynthetic pathway in Dioscorea and demonstrated the de novo biosynthesis of diosgenin in a yeast cell factory.First,we found that P450 gene duplication and neofunctionalization,driven by positive selection,played important roles in the origin of the diosgenin biosynthetic pathway.Subsequently,we found that the enrichment of diosgenin in the yam lineage was regulated by CpG islands,which evolved to regulate gene expression in the diosgenin pathway and balance the carbon flux between the biosynthesis of diosgenin and starch.Finally,by integrating genes fromplants,animals,and yeast,weheterologously synthesized diosgenin to 10mg/l in genetically-engineered yeast.Our study not only reveals the origin and evolutionary mechanisms of the diosgenin biosynthetic pathway in Dioscorea,but also introduces an alternative approach for the production of diosgenin through synthetic biology. | Jian Cheng Jing Chen Xiaonan Liu Xiangchen Li Weixiong Zhang Zhubo Dai Lina Lu Xiang Zhou Jing Cai Xueli Zhang Huifeng Jiang Yanhe Ma | 2021 | Plant Communications2021，2，1： | 2 |

| 9 | Surface modification of mesoporous silica nanoparticle with 4-triethoxysilylaniline to enhance seawater desalination properties of thin-film nanocomposite reverse osmosis membranes显示文摘Mesoporous silica nanoparticles(MSN),with higher water permeability than NaA zeolite,were used to fabricate thin-film nanocomposite(TFN)reverse osmosis(RO)membranes.However,only aminoalkyl-modified MSN and low-pressure(less than 2.1 MPa)RO membrane were investigated.In this study,aminophenyl-modified MSN(AMSN)were synthesized and used to fabricate high-pressure(5.52 MPa)RO membranes.With the increasing of AMSN dosage,the crosslinking degree of the aromatic polyamide decreased,while the hydrophilicity of the membranes increased.The membrane morphology was maintained to show a ridge-and-valley structure,with only a slight increase in membrane surface roughness.At the optimum conditions(AMSN dosage of 0.25 g/L),when compared with the pure polyamide RO membrane,the water flux of the TFN RO membrane(55.67 L/m^2/h)was increased by about 21.6%,while NaCl rejection(98.97%)was slightly decreased by only 0.29%.However,the water flux of the membranes was much lower than expected.We considered that the enhancement of RO membrane permeability is attributed to the reduction of the effective thickness of the PA layer. | Jian Wang Qun Wang Xueli Gao Xinxia Tian Yangyang Wei Zhen Cao Chungang Guo Huifeng Zhang Zhun Ma Yushan Zhang | 2020 | Frontiers of Environmental Science & Engineering2020，14，1： | 1 |
| 10 | A novel inflatable rings supported design and buoyancy-weight balance deformation analysis of stratosphere airships显示文摘Owing to the unique advantages in flight altitude,dwelling time and wide coverage area,stratospheric airships provide permanent monitoring and surveillance for both civil and military applications.Here we propose a semi-rigid stratosphere airship design with circumferential high-pressure inflatable rings and a longitudinal carbon fiber skeleton supported inside.We perform numerical simulations to analyze the deformation characteristics during the whole ascending and descending process.An equivalent internal gradient pressure model of helium is established based on the capsule shape and buoyancy-weight equilibrium conditions.The implicit dynamic method is used to deal with the large deformation of the airship capsule under a low negative pressure condition.Deformation and load-bearing performance of the airship capsule,inflatable ring,skeleton,and suspension line are obtained under different working conditions.The results show that the airship,supported with the inflatable rings and the suspension lines,effectively maintains the shape and ensures the stiffness during the ascending,dwelling,and descending stages,especially suffering from negative pressure. | Weinan GAO Ji ZHANG Teng MA Guochang LIN Yuanpeng LIU Changguo WANG Huifeng TAN | 2022 | Chinese Journal of Aeronautics2022，35，1： | 1 |
| 11 | Enhanced intermolecular interactions to improve twisted polymer photovoltaic performance显示文摘In polymer solar cells(PSCs), twisted polymer donors usually have low photovoltaic efficiencies due to their poor photoactive layer morphologies. Herein, we successfully improved twisted polymer(PBDT-3T) photovoltaic efficiency by employing C=O groups(PBDT-3TCO) to enhance intermolecular interactions. The maximum power conversion efficiency(PCE) of PBDT-3T is only 1.05%, while the PCE of PBDT-3TCO reaches 11.77% in non-fullerene(NF) PSCs. Both polymers-based PSCs show very similar open-circuit voltages but remarkable differences in their short-circuit currents and fill factors. The single crystals of both functionalized terthiophenes with methyl substituents demonstrate that the terthiophene with C=O units changes molecular pattern by forming intra/inter molecular S???O and O???H interactions but its molecular planarity does not significantly improve.Our comparative studies show that PBDT-3TCO with C=O units possesses a strong aggregation property and optimal photoactive layer morphology in NF PSCs. This study provides important insight into the design of high-performance twisted polymer donors for NF PSCs. | Cunbin An Jingming Xin Lanlan Shi Wei Ma Jianqi Zhang Huifeng Yao Sunsun Li Jianhui Hou | 2019 | Science China Chemistry2019，62，3： | 1 |

| 13 | Hot-melt extrusion promotes dissolution,extends“spring-parachute”process and inhibits crystallization in supersaturating microparticle systems显示文摘Despite the potential advantages of amorphism-induced supersaturation,the merit of new amorphiza-tion formation methods on the properties of the amorphous drug including the stability of the amor-phous state,dissolution/solubility,supersaturation,and'spring-parachute'process is still poorly understood,particularly for certain amorphous supersaturating drug delivery systems(aSDDS).The present work aimed to explore the detailed merit of current attractive amorphization manufacturing methods(i.g.,hot-melt extrusion(HME)technique)on the property improvement of aSDDS in form of amorphous solid dispersion microparticles by employing a model Bcs II drug nitrendipine and a polyvinylpyrrolidone-based model polymer copovidone.Many asDDS systems were developed by various methods,and their physicochemical properties were characterized by SEM,PXRD and DSC.HME-triggered amorphization induced superior supersaturation by the observation of the highest dissolution and solubility.HME induced the optimal supersaturation duration by the observed greatest extension of'spring-parachute'process(e.g,maximum AUCspring-parachute).HME technique is comparable with other techniques for the stabilization of amorphous state during storage.All aSDDS systems by HME and other methods showed improved long-term stability of the amorphous state in comparison to the pure amorphous drug.Fourier transformation infrared spectroscopy,Noyes-Whitney equation,nucleation theory and Gibbs free energy of transfer(△G)were used to analyze the underlying mechanisms.Mo-lecular mechanism studies indicated that HME caused a stronger crystallization inhibition effect in the asDDS systems than other methods,but molecular interaction is not a dominant mechanism for property enhancement caused by HME.For the mechanism associated with the polymer itself(PVPVA64),it could inhibit the drug recrystallization,solubilize the drug spontaneously and cause the improved molecular interactions in all aSDDS systems.This study provided a deep insight into detailed advantage of HME-triggered supersaturation/amorphization and facilitated the applications of the technique both in the field of particuology and in pharmaceutical industry. | Yanfei Zhang Huifeng Zhang Huan Yu Yinghui Ma Chengyi Hao Xiaoying Lin Yong Zhang Zhengqiang Li Xianrong Qi Jia Zeng Nianqiu Shi | 2023 | Particuology2023，，7： | 0 |
| 14 | Genetic Architecture of Childhood Kidney and Urological Diseases in China显示文摘Kidney disease is manifested in a wide variety of phenotypes,many of which have an important hereditary component.To delineate the genotypic and phenotypic spectrum of pediatric nephropathy,a multicenter registration system is being imple-mented based on the Chinese Children Genetic Kidney Disease Database(CCGKDD).In this study,all the patients with kidney and urological diseases were recruited from 2014 to 2020.Genetic analysis was conducted using exome sequencing for families with multiple affected individuals with nephropathy or clinical suspicion of a genetic kidney disease owing to early-onset or extrarenal features.The genetic diagnosis was confirmed in 883 of 2256(39.1%)patients from 23 provinces in China.Phenotypic profiles showed that the primary diagnosis included steroid-resistant nephrotic syndrome(SRNS,23.5%),glomerulonephritis(GN,32.2%),congenital anomalies of the kidney and urinary tract(CAKUT,21.2%),cystic renal disease(3.9%),renal calcinosis/stone(3.6%),tubulopathy(9.7%),and chronic kidney disease of unknown etiology(CKDu,5.8%).The pathogenic variants of 105 monogenetic disorders were identified.Ten distinct genomic disorders were identified as pathogenic copy number variants(CNVs)in 11 patients.The diagnostic yield differed by subgroups,and was highest in those with cystic renal disease(66.3%),followed by tubulopathy(58.4%),GN(57.7%),CKDu(43.5%),SRNS(29.2%),renal calcinosis/stone(29.3%)and CAKUT(8.6%).Reverse phenotyping permitted correct identification in 40 cases with clinical reassessment and unexpected genetic conditions.We present the results of the largest cohort of children with kidney disease in China where diagnostic exome sequencing was performed.Our data demonstrate the utility of family-based exome sequencing,and indicate that the combined analysis of genotype and phenotype based on the national patient registry is pivotal to the genetic diagnosis of kidney disease. | Ye Fang Hua Shi Tianchao Xiang Jiaojiao Liu Jialu Liu Xiaoshan Tang Xiaoyan Fang Jing Chen Yihui Zhai Qian Shen Guomin Li Li Sun Yunli Bi Xiang Wang Yanyan Qian Bingbing Wu Huijun Wang Wenhao Zhou Duan Ma Jianhua Mao Xiaoyun Jiang Shuzhen Sun Ying Shen Xiaorong Liu Aihua Zhang Xiaowen Wang Wenyan Huang Qiu Li Mo Wang Xiaojie Gao Yubin Wu Fang Deng Ruifeng Zhang Cuihua Liu Li Yu Jieqiu Zhuang Qing Sun Xiqiang Dang Haitao Bai Ying Zhu Siguang Lu Bili Zhang Xiaoshan Shao Xuemei Liu Mei Han Lijun Zhao Yuling Liu Jian Gao Ying Bao Dongfeng Zhang Qingshan Ma Liping Zhao Zhengkun Xia Biao Lu Yulong Wang Mengzhun Zhao Jianjiang Zhang Shan Jian Guohua He Huifeng Zhang Bo Zhao Xiaohua LI Feiyan Wang Yufeng Li Hongtao Zhu Xinhui Luo Jinghai Li Jia Rao Hong Xu | 2021 | Phenomics2021，1，3： | 0 |

| 17 | Vegetation C–N–P accumulation and allocation patterns at the community level in early restored plantations in the loess hilly-gully region显示文摘Accumulation of vegetation biomass is a crucial process for carbon fixation in the early stage of afforestation and a primary driving force for subsequent ecological functions.Accurately assessing the storage and allocation of elements in plantations is essential for their management and estimating carbon sink capacity.However,current knowledge of the storage and allocation patterns of elements within plant organs at the community level is limited.To clarify the distribution patterns of elements in plant organs at the community level,we measured the biomass within plant organs of five typical plantations in the early stage of afforestation in the loess hilly-gully region.We assessed the main drivers of element accumulation and distribution by employing redundancy analysis and random forest.Results revealed significant differences in biomass storages among plantations and a significant effect of plantation type on the storages of elements within plant organs.Furthermore,the dominant factors influencing C–N–P storage and allocation at the community level were found to be inconsistent.While the storage of elements was mainly influenced by stand openness,total soil nitrogen,and plant diversity,the allocation of elements in organs was mainly influenced by stand openness and soil water content.Overall,the spatial structure of the community had an important influence on both element storage and allocation,but soil conditions played a more important role in element allocation than in storage.Random forest results showed that at the community level,factors influencing element storage and allocation within plant organs often differed.The regulation of elemental storage could be regulated by the major growth demand resources,while the allocation was regulated by other limiting class factors,which often differed from those that had a significant effect on element storage.The differences in plant organ elemental storage and allocation drivers at the community level reflect community adaptation strategies and the regulation of resources by ecosystems in combination with plants.Our study provides valuable insights for enhancing plantation C sink estimates and serves as a reference for regulating element storage and allocation at the local scale. | Huifeng Wu Baoan Hu Ying Ma Wenkai Shi Xiaoqin Cheng Fengfeng Kang Hairong Han | 2023 | Forest Ecosystems2023，10，4： | 0 |
| 18 | A Thiazole-Based Polymer Donor for Efficient Organic Solar Cells显示文摘The development of new materials plays a critical role in improving the efficiency of organic solar cells(OSCs).At present,the relatively high-lying highest occupied molecular orbital(HOMO)level of the high-efficiency polymer donor is regarded as one of the main reasons for the low open-circuit voltage(V_(OC)).In this work,we introduced the strong electron-withdrawing thiazole unit into the construction of a polymer donor.We designed and prepared an alternating donor-acceptor material,namely PSZ,by copolymerizing 4-methyl thiazole with an electron-donating benzodithiophene unit and studied its application in high-efficiency OSCs.The optical and electrical properties of the new material were characterized by UV-Vis absorption spectroscopy and electrochemical cyclic voltammetry.Results show that PSZ is a typical wide-bandgap material with a high optical bandgap of 2.0 eV and a deep HOMO level of-5.70 eV.When a non-fullerene BTP-eC9 was selected as the acceptor material,V_(OC) reached 0.88 V in the resulting device,and the corresponding power conversion efficiency(PCE)was8.15%.In addition,when PSZ was added as the third component to the binary photoactive combination with PBDB-TF as the donor and BTP-eC9 as the acceptor,V_(OC) of the cell device could be increased,thereby obtaining a high PCE of 17.4%.These results indicated that introducing thiazole units into polymer donors can remarkably reduce the HOMO levels and improve V_(OC) and PCE in OSCs. | Ye Xu Huifeng Yao Tao Zhang Lijiao Ma Jianhui Hou | 2022 | Transactions of Tianjin University2022，28，5： | 0 |

| 20 | Synergistic effect of V and Fe in Ni/Fe/V ternary layered double hydroxides for efficient and durable oxygen evolution reaction显示文摘High-performance and stable electrocatalysts are vital for the oxygen evolution reaction(OER).Herein,via a one-pot hydrothermal method,Ni/Fe/V ternary layered double hydroxides(NiFeV-LDH)derived from Ni foam are fabricated to work as highly active and durable electrocatalysts for OER.By changing the feeding ratio of Fe and V salts,the prepared ternary hydroxides were optimized.At an Fe:V ratio of 0.5:0.5,NiFeV-LDH exhibits outstanding OER activity superior to that of the binary hydroxides,requiring overpotentials of 269 and 274 mV at 50 mA·cm^(−2)in the linear sweep voltammetry and sampled current voltammetry measurements,respectively.Importantly,NiFeV-LDH shows extraordinary long-term stability(≥75 h)at an extremely high current density of 200 mA·cm^(−2).In contrast,the binary hydroxides present quick decay at 200 mA·cm^(−2)or even reduced current densities(150 and 100 mA·cm^(−2)).The outstanding OER performance of NiFeV-LDH benefits from the synergistic effect of V and Fe while doping the third metal into bimetallic hydroxide layers:(a)Fe plays a crucial role as the active site;(b)electron-withdrawing V stabilizes the high valence state of Fe,thus accelerating the OER process;(c)V further offers great stabilization for the formed intermediate of FeOOH,thus achieving superior durability. | Lihong Chen Ruxin Deng Shaoshi Guo Zihuan Yu Huiqin Yao Zhenglong Wu Keren Shi Huifeng Li Shulan Ma | 2023 | Frontiers of Chemical Science and Engineering2023，17，1： | 0 |
