| 1 | Hierarchical construction of CNT networks in aramid papers for high-efficiency microwave absorption显示文摘Carbon nanotubes(CNTs)incorporated polymeric composites have been extensively investigated for microwave absorption at target frequencies to meet the requirement of radar cross-section reduction.In this work,a strategy of efficient utilization of CNT in producing CNT incorporated aramid papers is demonstrated.The layer-by-layer self-assembly technique is used to coat the surfaces of meta-aramid fibers and fibrils with CNT,providing novel raw materials available for the large-scale papermaking.The hierarchical construction of CNT networks resolves the dilemma of increasing CNT content and avoiding the agglomeration of CNT,which is a frequent challenge for CNT incorporated polymeric composites.The composite paper,which contains abundant heterogeneous interfaces and long-range conductive networks,is capable of reaching a high permittivity and dielectric loss tangent at a low CNT loading,its complex permittivity is,so far,adjustable in the range of(1.20−j0.05)to(25.17−j18.89)at 10 GHz.Some papers with optimal matching thicknesses achieve a high-efficiency microwave absorption with a reflection loss lower than−10 dB in the entire X-band. | You Wu Li Chen Yixuan Han Panbo Liu Haihong Xu Guanze Yu Yingying Wang Tao Wen Wenbo Ju Junwei Gu | 2023 | Nano Research2023，16，5： | 9 |
| 2 | Manipulation of Band Degeneracy and Lattice Strain for Extraordinary PbTe Thermoelectrics显示文摘Maximizing band degeneracy and minimizing phonon relaxation time are proven to be successful for advancing thermoelectrics.Alloying with monotellurides has been known to be an effective approach for converging the valence bands of PbTe for electronic improvements,while the lattice thermal conductivity of the materials remains available room for being further reduced.It is recently revealed that the broadening of phonon dispersion measures the strength of phonon scattering,and lattice dislocations are particularly effective sources for such broadening through lattice strain fluctuations.In this work,a fine control of MnTe and EuTe alloying enables a significant increase in density of electron states near the valence band edge of PbTe due to involvement of multiple transporting bands,while the creation of dense in-grain dislocations leads to an effective broadening in phonon dispersion for reduced phonon lifetime due to the large strain fluctuations of dislocations as confirmed by synchrotron X-ray diffraction.The synergy of both electronic and thermal improvements successfully leads the average thermoelectric figure of merit to be higher than that ever reported for p-type PbTe at working temperatures. | Yixuan Wu Pengfei Nan Zhiwei Chen Zezhu Zeng Siqi Lin Xinyue Zhang Hongliang Dong Zhiqiang Chen Hongkai Gu Wen Li Yue Chen Binghui Ge Yanzhong Pei | 2020 | Research2020，，1： | 6 |
| 3 | Photonic synapses with ultralow energy consumption for artificial visual perception and brain storage显示文摘The human visual system,dependent on retinal cells,can be regarded as a complex combination of optical system and nervous system.Artificial retinal system could mimic the sensing and processing function of human eyes.Optically stimulated synaptic devices could serve as the building blocks for artificial retinas and subsequent information transmission system to brain.Herein,photonic synaptic transistors based on polycrystalline MoS_(2),which could simulate human visual perception and brain storage,are presented.Moreover,the photodetection range from visible light to near-infrared light of MoS_(2) multilayer could extend human eyes’vision limitation to near-infrared light.Additionally,the photonic synaptic transistor shows an ultrafast speed within 5μs and ultralow power consumption under optical stimuli about 40 aJ,several orders of magnitude lower than biological synapses(50 ms and 10 fJ).Furthermore,the backgate control could act as emotional modulation of the artificial brain to enhance or suppress memory function,i.e.the intensity of photoresponse.The proposed carrier trapping/detrapping as the main working mechanism is presented for the device.In addition,synaptic functionalities including short synaptic plasticity,long synaptic plasticity and paired-pulse facilitation could be successfully simulated based on the prepared device.Furthermore,the large difference between short synaptic plasticity and long synaptic plasticity reveals the better image pre-processing function of the prepared photonic synapses.The classical Pavlovian conditioning associated with the associative learning is successfully implemented as well.Therefore,the efficient and rich functionalities demonstrate the potential of the MoS_(2) synaptic device that integrates sensing-memory-preprocessing capabilities for realizing artificial neural networks with different emotions that mimic human retina and brain. | Caihong Li Wen Du Yixuan Huang Jihua Zou Lingzhi Luo Song Sun Alexander OGovorov Jiang Wu Hongxing Xu Zhiming Wang | 2022 | Opto-Electronic Advances2022，5，9： | 3 |
| 4 | Plasmonic coupling-enhanced in situ photothermal nanoreactor with shape selective catalysis for C–C coupling reaction显示文摘Carbon-carbon(C–C)coupling reactions represent one of the most powerful tools for the synthesis of complex natural products,bioactive molecules developed as drugs and agrochemicals.In this work,a multifunctional nanoreactor for C–C coupling reaction was successfully fabricated via encapsulating the core-shell Cu@Ni nanocubes into ZIF-8(Cu@Ni@ZIF-8).In this nanoreactor,Ni shell of the core-shell Cu@Ni nanocubes was the catalytical active center,and Cu core was in situ heating source for the catalyst by absorbing the visible light.Moreover,benefiting from the plasmonic resonance effect between Cu@Ni nanocubes encapsulated in ZIF-8,the absorption range of nanoreactor was widened and the utilization rate of visible light was enhanced.Most importantly,the microporous structure of ZIF-8 provided shape-selective of reactant.This composite was used for the highly shape-selective and stable photocatalysed C–C coupling reaction of boric acid under visible light irradiation.After five cycles,the nanoreactor still remained high catalytical activity.This Cu@Ni@ZIF-8 nanoreactor opens a way for photocatalytic C–C coupling reactions with shape-selectivity. | Zhenxing Li Yixuan Gong Xin Zhang Yangyang Wen Jiasai Yao Mingliang Hu Miao He Jiahao Liu Rui Li Fuqiang Wang Chuanxin Zhang | 2020 | Nano Research2020，13，10： | 2 |
| 5 | RNA-Seq analysis reveals the growth and photosynthetic responses of rapeseed(Brassica napus L.)under red and blue LEDs with supplemental yellow,green,or white light显示文摘Compound light is required for plant growth and development,but the response mechanisms of plants are undercharacterized and not fully understood.The present study was undertaken to evaluate the effect of supplemental light(green light,G;white light,W;yellow light,Y)added to red–blue light(RB)and sole W on the growth and photosynthesis of rapeseed seedlings.The results revealed that supplemental G/W improved the growth and photosynthesis of seedlings,but supplemental Y significantly reduced the photosynthetic rate and palisade tissue layer.Sole W caused similar responses in terms of growth,leaf development,oxidative damage,and antioxidant capability as supplemental Y.In total,449,367,813,and 751 differentially expressed genes(DEGs)were identified under supplemental G,Y,and W and sole W,respectively,compared to RB.The DEGs under different lights were closely associated with pathways such as light stimulus and high-light response,root growth,leaf development,photosynthesis,photosynthesis-antenna proteins,carbohydrate synthesis and degradation,secondary metabolism,plant hormones,and antioxidant capacity,which contributed to the distinct growth and photosynthesis under different treatments.Our results suggest that Y is more likely substituted by other wavelengths to achieve certain effects similar to those of supplemental Y,while G has a more distinctive effect on rapeseed.Taken together,supplementation RB with G/W promotes the growth of rapeseed seedlings in a controlled environment. | Xiaoying Liu Zheng Chen Mohammad Shah Jahan Yixuan Wen Xuyang Yao Haifeng Ding Shirong Guo Zhigang Xu | 2020 | Horticulture Research2020，7，1： | 1 |
| 6 | A new academic impact metric for evaluating geographic simulation models显示文摘Geographic simulation models can be used to explore and better understand the geographical environment. Recent advances in geographic and socio-environmental research have led to a dramatic increase in the number of models used for this purpose. Some model repositories provide opportunities for users to explore and apply models,but few provide a general evaluation method for assessing the applicability and recognition of models. In this study,an academic impact evaluation method for models is proposed. Five indices are designed based on their pertinence. The analytical hierarchy process is used to calculate the index weights,and the academic impacts of models are quantified with the weighted sum method. The time range is controlled to evaluate the life-term and annual academic impacts of the models. Some models that met the evaluation criteria from different domains are then evaluated. The results show that the academic impact of a model can be quantified with the proposed method,and the major research areas that models impact are identified. | Kai Xu Min Chen Albert J.Kettner C.Michael Barton Barry F.W.Croke Anthony J.Jakeman Daniel P.Ames Hsiao-Hsuan Wang Susan M.Cuddy Songshan Yue Yongning Wen Fengyuan Zhang Yixuan Zhang Guonian Lü | 2022 | International Journal of Digital Earth2022，15，1： | 0 |

| 8 | Phloem unloading in cultivated melon fruits follows an apoplasmic pathway during enlargement and ripening显示文摘Melon(Cucumis melo L.)has a long history of cultivation worldwide.During cultivation,domestication,and selection breeding,the sugar content of mature melon fruits has been significantly increased.Compared with unsweet melon and wild melon,rapid sucrose accumulation can occur in the middle and late stages of sweet melon fruit development.The phloem unloading pathway during the evolution and development of melon fruit has not been identified and analyzed.In this study,the phloem unloading pathway and the function of related sugar transporters in cultivated and wild melon fruits were analyzed by CFDA[5(6)-carbofluorescein diacetate]and esculin tracing,cytological pathway observation,qRT–PCR,and gene function analysis,etc.Results show that the phloem unloading pathway of wild melon fruit is largely symplastic,whereas the phloem unloading pathway of cultivated melon fruit shifts from symplastic to apoplasmic during development.According to a fruit grafting experiment,the fruit sink accumulates sugars independently.Correlation analysis showed that the expression amounts of several sucrose transporter genes were positively correlated with the sucrose content of melon fruit.Furthermore,CmSWEET10 was proved to be a sucrose transporter located on the plasma membrane of the phloem and highly expressed in the premature stage of sweet melon fruits,which means it may be involved in phloem apoplast unloading and sucrose accumulation in sweet melon fruits.Finally,we summarize a functional model of related enzymes and sugar transporters involved in the apoplast unloading of sweet melon fruits during enlargement and sucrose accumulation. | Yixuan Zhou Kexin Li Suying Wen Dong Yang Jun Gao Ziwei Wang Peilu Zhu Zhilong Bie Jintao Cheng | 2023 | Horticulture Research2023，10，8： | 0 |
| 9 | Toward batch synthesis of high-quality graphene by cold-wall chemical vapor deposition approach显示文摘Chemical vapor deposition(CVD)has emerged as a promising approach for the controlled growth of graphene films with appealing scalability,controllability,and uniformity.However,the synthesis of high-quality graphene films still suffers from low production capacity and high energy consumption in the conventional hot-wall CVD system.In contrast,owing to the different heating mode,cold-wall CVD(CW-CVD)system exhibits promising potential for the industrial-scale production,but the quality of as-received graphene remains inferior with limited domain size and high defect density.Herein,we demonstrated an efficient method for the batch synthesis of high-quality graphene films with millimeter-sized domains based on CW-CVD system.With reduced defect density and improved properties,the as-received graphene was proven to be promising candidate material for electronics and anti-corrosion application.This study provides a new insight into the quality improvement of graphene derived from CW-CVD system,and paves a new avenue for the industrial production of high-quality graphene films for potential commercial applications. | Kaicheng Jia Ziteng Ma Wendong Wang Yongliang Wen Huanxin Li Yeshu Zhu Jiawei Yang Yuqing Song Jiaxin Shao Xiaoting Liu Qi Lu Yixuan Zhao Jianbo Yin Luzhao Sun Hailin Peng Jincan Zhang Li Lin Zhongfan Liu | 2022 | Nano Research2022，15，11： | 0 |
| 10 | Matrix from urine stem cells boosts tissue-specific stem cell mediated functional cartilage reconstruction显示文摘Articular cartilage has a limited capacity to self-heal once damaged.Tissue-specific stem cells are a solution for cartilage regeneration;however,ex vivo expansion resulting in cell senescence remains a challenge as a large quantity of high-quality tissue-specific stem cells are needed for cartilage regeneration.Our previous report demonstrated that decellularized extracellular matrix(dECM)deposited by human synovium-derived stem cells(SDSCs),adipose-derived stem cells(ADSCs),urine-derived stem cells(UDSCs),or dermal fibroblasts(DFs)provided an ex vivo solution to rejuvenate human SDSCs in proliferation and chondrogenic potential,particularly for dECM deposited by UDSCs.To make the cell-derived dECM(C-dECM)approach applicable clinically,in this study,we evaluated ex vivo rejuvenation of rabbit infrapatellar fat pad-derived stem cells(IPFSCs),an easily accessible alternative for SDSCs,by the abovementioned C-dECMs,in vivo application for functional cartilage repair in a rabbit osteochondral defect model,and potential cellular and molecular mechanisms underlying this rejuvenation.We found that C-dECM rejuvenation promoted rabbit IPFSCs’cartilage engineering and functional regeneration in both ex vivo and in vivo models,particularly for the dECM deposited by UDSCs,which was further confirmed by proteomics data.RNA-Seq analysis indicated that both mesenchymal-epithelial transition(MET)and inflammation-mediated macrophage activation and polarization are potentially involved in the C-dECM-mediated promotion of IPFSCs’chondrogenic capacity,which needs further investigation. | Ming Pei Yixuan Amy Pei Sheng Zhou Elmira Mikaeiliagah Christopher Erickson Benjamin Giertych Halima Akhter Lei Wang Amanda Stewart Joshua Parenti Bin Wang Sijin Wen Sotcheadt Sim Eric Quenneville Kirk C.Hansen Steven Frisch Gangqing Hu | 2023 | Bioactive Materials2023，，5： | 0 |
| 11 | Microstructure and cavitation erosion behavior of sputtered NiCrAlTi coatings with and without N incorporations显示文摘The NiCrAlTi coatings free of N and with N incorporations were deposited on austenitic stainless steel304 L by magnetron sputtering in Ar and in gas mixture of Ar and N2,respectively.The N incorporated in the coatings existed as nitride precipitates(from^3 vol.%to^17 vol.%)after vacuum annealing.All the NiCrAlTi coatings,whatever free of N or with N incorporations,exhibited better resistance against cavitation erosion than ion plating Ti N coating and the substrate 304 L in ultrasonic cavitation tests.The NiCrAlTi coating free of N incorporation presents superior cavitation erosion resistance.However,the nitrogen incorporation within the NiCrAlTi coatings showed negative effects on the resistance against cavitation erosion. | Zhengliang Liu Shenglong Zhu Mingli Shen Yixuan Jia Wen Wang Fuhui Wang | 2020 | Journal of Materials Science & Technology2020，54，19： | 0 |
| 12 | MnTe_(2) as a novel promising thermoelectric material显示文摘Semiconducting manganese ditelluride(MnTe_(2))crystalizes in a high symmetry cubic structure with sufficient band gap and consists of nontoxic elements only,therefore is focused on in this work for its potential thermoelectric applications.This material intrinsically comes with a very low hole concentration of 10^(19)cm^(-3),which can be successfully increased to 4×10^(20)cm^(-3)through Ag-doping at Mn site.Such a broad carrier concentration enables an effective optimization on thermoelectric power factor,and the doping process effectively reduces the lattice thermal conductivity down to~0.5 W/m-K due to the phonons scattered by additional point defects.As a result,a peak zT of~0.7 is obtained in p-type conduction.Moreover,the SPB model with acoustic scattering estimates the electronic properties well,which also enables insight into the underlying physical parameters related to the thermoelectric performance.Importantly,band structure calculation suggests a potentially higher thermoelectric performance for n-type conduction due to both higher band degeneracy and lower band effective mass.This work reveals MnTe_(2)is a novel promising thermoelectric material. | Yidong Xu Wen Li Chen Wang Zhiwei Chen Yixuan Wu Xinyue Zhang Juan Li Siqi Lin Yue Chen Yanzhong Pei | 2018 | Journal of Materiomics2018，4，3： | 0 |
| 13 | In situ TEM visualization of Ag catalysis in Li-O_(2)nanobatteries显示文摘Lithium-oxygen(Li-O_(2))batteries have been considered as an ideal solution to solving the global energy crisis.Silver(Ag)and Agbased catalyst have been extensively studied due to their high catalytic activities in Li-O_(2)batteries.However,it remains a challenge to track the catalytic mechanism during the charge/discharge process.Here,a nanoscale processing method was used to assemble a Li-O_(2)nanobattery in an aberration-corrected environmental transmission electron microscope(ETEM),where a single Ag nanowire(NW)was used as catalyst for O_(2)electrode.A visualization of the lithium ion insertion process during the electrochemical reactions was achieved in this nanobattery.Numerous Ag nanoparticles(NPs)were observed on the surface of the Ag NW,which were covered by the discharge product Li2O_(2).By simultaneously studying the evolution of the interface and the phase transformation,it can be concluded that these Ag NPs wrapped around Ag NW acted as catalyst during the subsequent charge/discharge reaction.Based on these studies,Ag NPs decorated on porous carbon were synthesized,it can simultaneously improve the cycling stability(100 cycles)and the maximum specific capacity(17,371 mAh·g^(−1)at a current density of 100 mA·g^(−1))in a coin cell Li-O_(2)battery.This study suggests that nanoscale Ag may be a promising catalyst for Li-O_(2)battery. | Yixuan Wen Shuaijun Ding Chongchong Ma Peng Jia Wei Tu Yunna Guo Shuang Guo Wei Zhou Xiaoqian Zhang Jianyu Huang Liqiang Zhang Tongde Shen Yuqing Qiao | 2023 | Nano Research2023，16，5： | 0 |
| 14 | Simulation Method and Feature Analysis of Shutdown Pressure Evolution During Multi-Cluster Fracturing Stimulation显示文摘Multistage multi-cluster hydraulic fracturing has enabled the economic exploitation of shale reservoirs,but the interpretation of hydraulic fracture parameters is challenging.The pressure signals after pump shutdown are influenced by hydraulic fractures,which can reflect the geometric features of hydraulic fracture.The shutdown pressure can be used to interpret the hydraulic fracture parameters in a real-time and cost-effective manner.In this paper,a mathematical model for shutdown pressure evolution is developed considering the effects of wellbore friction,perforation friction and fluid loss in fractures.An efficient numerical simulation method is established by using the method of characteristics.Based on this method,the impacts of fracture half-length,fracture height,opened cluster and perforation number,and filtration coefficient on the evolution of shutdown pressure are analyzed.The results indicate that a larger fracture half-length may hasten the decay of shutdown pressure,while a larger fracture height can slow down the decay of shutdown pressure.A smaller number of opened clusters and perforations can significantly increase the perforation friction and decrease the overall level of shutdown pressure.A larger filtration coefficient may accelerate the fluid filtration in the fracture and hasten the drop of the shutdown pressure.The simulation method of shutdown pressure,as well as the analysis results,has important implications for the interpretation of hydraulic fracture parameters. | Huaiyin He Longqing Zou Yanchao Li Yixuan Wang Junxiang Li Huan Wen Bei Chang Lijun Liu | 2024 | Energy Engineering2024，121，1： | 0 |
