| 1 | Lithium–matrix composite anode protected by a solid electrolyte layer for stable lithium metal batteries显示文摘Lithium (Li) metal with an ultrahigh specific theoretical capacity and the lowest reduction potential is strongly considered as a promising anode for high-energy-density batteries. However, uncontrolled lithium dendrites and infinite volume change during repeated plating/stripping cycles hinder its practical applications immensely. Herein, a house-like Li anode (housed Li) was designed to circumvent the above issues. The house matrix was composed of carbon fiber matrix and affords a stable structure to relieve the volume change. An artificial solid electrolyte layer was formed on composite Li metal, just like the roof of a house, which facilitates uniform Li ions diffusion and serves as a physical barrier against electrolyte corrosion. With the combination of solid electrolyte layer and matrix in the composite Li metal anode, both dendrite growth and volume expansion are remarkably inhibited. The housed Li|LiFePO4 batteries exhibited over 95% capacity retention after 500 cycles at 1.0 C in coin cell and 85% capacity retention after 80 cycles at 0.5 C in pouch cell. The rationally combination of solid electrolyte layer protection and housed framework in one Li metal anode sheds fresh insights on the design principle of a safe and long-lifespan Li metal anode for Li metal batteries. | Xin Shen Xinbing Cheng Peng Shi Jiaqi Huang Xueqiang Zhang Chong Yan Tao Li Qiang Zhang | 2019 | Journal of Energy Chemistry2019,28,10: | 23 |
| 2 | Spatial and Temporal Variability of PM_(2.5) Concentration in China显示文摘PM_(2.5) has become an increasing public concern recently because of its visibility reduction and severe health risks. For the whole year of 2013, hourly PM_(2.5) data of 496 monitoring sites scattered in 74 cities of China are collected to analyze temporal and spatial variability of PM_(2.5) concentration. Different temporal scales(seasonal variation, monthly variation and daily variation) and spatial scales(urban versus rural, typical areas and national scale) are discussed. Results show that PM_(2.5) concentration changes significantly in both long-term and short-term scales. An apparent bimodal pattern exists in daily variation of PM_(2.5) concentration and the daytime peak appears around 10:00 am while the lowest concentration appears around 16:00 pm. Spatial autocorrelation analysis and Ordinary Kriging are used to characterize spatial variability. Moran's I of PM_(2.5) concentration in three typical regions, the Beijing-Tianjin-Hebei region, the Yangtze River Delta region and the Pearl River Delta region, is 0.906, 0.693, 0.746, respectively, which indicates that PM_(2.5) is strong spatial correlated. Spatial distribution of annual PM_(2.5) concentration simulated by Ordinary Kriging shows that 7.94 million km2(83%) areas fail in meeting the requirement of China's National Ambient Air Quality Standards Level-2(35 mg/m3) and there are at least three concentrated highly polluted areas across the country. | XU Gang JIAO Limin ZHAO Suli CHENG Jiaqi | 2016 | Wuhan University Journal of Natural Sciences2016,21,4: | 9 |
| 3 | Mesoporous Graphene Hosts for Dendrite-Free Lithium Metal Anode in Working Rechargeable Batteries显示文摘Lithium(Li) metal anode has received extensive attentions due to its ultrahigh theoretical capacity and the most negative electrode potential. However, dendrite growth severely impedes the practical applications of the Li metal anode in rechargeable batteries. In this contribution, a mesoporous graphene with a high specific surface area was synthesized to host the Li metal anode. The mesoporous graphene host(MGH) has a high specific surface area(2090 m^2/g), which affords free space and an interconnected conductive pathway for Li plating and stripping, thus alleviating the volume variation and reducing the generation of dead Li during repeated cycles. More importantly, the high specific surface area of MGH efficiently reduces the local current density of the electrode, which favors a uniform Li nucleation and plating behavior, rendering a dendritefree deposition morphology at a low overpotential. These factors synergistically boost the Li utilization(90.1% vs. 70.1% for Cu foil) and life span(150 cycles vs. 100 cycles for Cu foil) with a low polarization of MGH electrode at an ultrahigh current of 15.0 mA/cm^2. The as-prepared MGH can provide fresh insights into the electrode design of the Li metal anode operating at high rates. | He Liu Xinbing Cheng Rui Zhang Peng Shi Xin Shen Xiaoru Chen Tao Li Jiaqi Huang Qiang Zhang | 2020 | Transactions of Tianjin University2020,26,2: | 9 |

| 6 | Stable interfaces constructed by concentrated ether electrolytes to render robust lithium metal batteries显示文摘Lithium metal batteries(LMBs)are highly considered as promising candidates for next-generation energy storage systems.However,routine electrolytes cannot tolerate the high potential at cathodes and low potential at anodes simultaneously,leading to severe interfacial reactions.Herein,a highly concentrated electrolyte(HCE)region trapped in porous carbon coating layer is adopted to form a stable and highly conductive solid electrolyte interphase(SEI)on Li metal surface.The protected Li metal anode can potentially match the high-voltage cathode in ester electrolytes.Synergistically,this ingenious design promises high-voltage-resistant interfaces at cathodes and stable SEI with abundance of inorganic components at anodes simultaneously in high-voltage LMBs.The feasibility of this interface-regulation strategy is demonstrated in Li|LiFePO_(4) batteries,realizing a lifespan twice as long as the routine cells,with a huge capacity retention enhancement from 46.4%to 88.7%after 100 cycles.This contribution proof-ofconcepts the emerging principles on the formation and regulation of stable electrode/electrolyte interfaces in the cathode and anode simultaneously towards the next-generation high-energy-density batteries. | He Liu Tao Li Xiangqun Xu Peng Shi Xueqiang Zhang Rui Xu Xinbing Cheng Jiaqi Huang | 2021 | Chinese Journal of Chemical Engineering2021,34,9: | 5 |

| 8 | Diversity of Sex Types and Seasonal Sexual Plasticity in a Cucumber Germplasm Collection显示文摘The sex type of a cucumber plant is determined by the proportion of male, female and hermaphrodite flowers that it bears and is an important factor that affects fruit yield. In this paper, the sex types and seasonal sexual stabilities of 322 accessions of cucumber germplasm were identified. This germplasm collection displayed a great variety of sex types. We used an updated 10-type sex classification system based on the flower types present and the proportion of nodes with pistillate flowers(PNPF). The PNPF ranges of all the accessions were 2.12%–100% in spring and 0–100% in autumn. A total of 81.37% of the accessions had PNPFs of 10%–50% in spring, but most(84.78%) accessions were reduced to 0–20% PNPF in autumn. The range of reduction of PNPF from spring to autumn was 0–67.91%. In other words, most of the germplasm was normal monoecious(31.68%) or subandroecious(62.73%) in spring, but 94.10% of the accessions were subandroecious in autumn. According to the statistical evaluation of the difference in PNPFs between the two seasons, each accession could be classified into one of three groups: seasonally stable, seasonally sensitive and highly seasonally sensitive, accounting for 10.56%, 20.50% and 68.94% of the accessions, respectively. With a few exceptions, the seasonal PNPF differences were positively correlated with the PNPFs in a given season for most accessions. These results provided useful information and materials for sex expression mechanism research and for breeding cucumbers with high and stable yields. | DOU Xinxin SHEN Di ZHANG Xiaohui CHENG Jiaqi LI Sigeng SONG Jiangping WANG Haiping ZHANG Wei LI Xixiang | 2015 | Horticultural Plant Journal2015,1,2: | 3 |
| 9 | An elevated preoperative serum calcium level is a significant predictor for positive peritoneal cytology in endometrial carcinoma显示文摘Objective:To evaluate preoperative serum calcium concentration and investigate the association between calcium level and positive peritoneal cytology in endometrial carcinoma(EC).Methods:A total of 510 patients who were diagnosed with EC and had surgery were initially enrolled in this study at Peking University People's Hospital between January 2012 and December 2016.Clinical characteristics and preoperative serum calcium,albumin,carbohydrate antigen(CA)125,CA19-9,carcinoembryonic antigen(CEA)were extracted from patient records and evaluated according to postoperative peritoneal cytology.Predictive factors were assessed with Cox univariate and multivariate analyses.Factors selected from multivariate analysis results were used to build a predictive model.Results:A total of 510 patients are identified in our database and 444 patients who fulfilled inclusion and exclusion criteria are included in this study.Univariate analysis revealed that ionized calcium concentration was closely related to positive peritoneal cytology,tumor grade and lymph-vascular space invasion(LVSI).Moreover,peritoneal cytology was significantly associated with hypertension,tubal ligation,serum CA125,CA19-9,CEA and ionized calcium level.Multivariate analysis revealed that albumin-adjusted calcium level,CA125 and tubal ligation were independent predictive factors of positive peritoneal cytology(P<0.05).A combination of ionized calcium level with the other two indexes yielded significantly great area under the curve(AUC=0.824).Conclusions:This study enhanced the value of preoperative ionized calcium level.We also identified several potential biomarkers to predict positive peritoneal cytology in EC patients before surgery. | Xingchen Li Yuan Cheng Yangyang Dong Boqiang Shen Xiao Yang Jiaqi Wang Jingyi Zhou Jianliu Wang | 2019 | Chinese Journal of Cancer Research2019,31,6: | 3 |

| 11 | Giant enhancement of photoluminescence quantum yield in 2D perovskite thin microplates by graphene encapsulation显示文摘The optoelectronic performances of the layered materials are strongly dependent on the thickness of the samples due to the surface effect.As the size of the samples decreases to few nanometers,the surface depletion field and surface defect density are prominent arising from the large surface to volume ratio.For instance,thin two-dimensional(2D)organic-inorganic hybrid perovskite microplates usually exhibit a rather low photoluminescence quantum yield(PLQY),owning to the strong surface effect.Here,we report that the PLQY can be enhanced as large as 28 times in(iso-BA)2Pbl4(BA=C4H9NH3)2D perovskite thin microplates encapsulated by graphene,resulting in that the PLQY is more than 18%for the microplate with a thickness of 6.7 nm at 78 K.As the thickness of the 2D perovskite microplate increases,the enhancement is gradually reduced and finally vanishes.This observation is in striking contrast to that in monolayer transition metal dichalcogenides(TMDs),when the PLQY is quenched by covering a layer of graphene due to the efficient charge transfer.The enhancement of PLQY in 2D perovskites can be mainly ascribed to the reduced quantum confined Stark effect(QCSE)due to the reduced surface depletion field after covering graphene flake,resulting in the enhanced radiative recombination efficiency.Our findings provide a cost-effective approach to enhance the luminescence,which may pave the way toward high performance light emitting devices based on 2D perovskites. | Wancai Li Jiaqi Ma Xue Cheng Dehui Li | 2021 | Nano Research2021,14,6: | 3 |
| 12 | Novel Kriging-Based Decomposed-Coordinated Approach for Estimating the Clearance Reliability of Assembled Structures显示文摘Turbine blisks are assembled using blades,disks and casings.They can endure complex loads at a high temperature,high pressure and high speed.The safe operation of assembled structures depends on the reliability of each component.Monte Carlo(MC)simulation is commonly used to analyze structural reliability,but this method needs to run thousands of computations.In order to assess the clearance reliability of assembled structures in an efficient and precise manner,the novel Kriging-based decomposed-coordinated(DC)(DCNK)approach is proposed by integrating the DC strategy,the Kriging model and the importance sampling-based Markov chain(MCIS)technique.In this method,the DC strategy is used to decompose a multi-objective problem into many single-objective problems.The relationships between these many single-objectives and the overall objective are then coordinated.The Kriging model is applied to establish the limit state functions of the single-objectives and multi-objective problems,while the MCIS method is used to assess the structural assembled clearance reliability.Moreover,a highly nonlinear complex compound function is first utilized to verify the DCNK model from a mathematical perspective.Then,the reliability of an aeroengine high-pressure turbine(HPT)blade-tip radial running clearance(BTRRC)is analyzed to validate the DCNK approach by considering thermo-structural interaction.The analytical results show that the reliability is 0.9976 when the allowance value of the BTTRC is 1.7650×10^(−3)m.Compared with different methodologies(including direct simulation,the classical Kriging model,and the weighted response surface method(WRSM)),the proposed method holds obvious advantages in computing time and precision,as well as simulation efficiency and precision.The efforts of this paper provide a useful approach to analyzing assembled clearance reliability and contribute to the development of structural reliability theory. | Da Teng Yunwen Feng Cheng Lu Chengwei Fei Jiaqi Liu Xiaofeng Xue | 2021 | Computer Modeling in Engineering & Sciences2021,,11: | 2 |

| 14 | Novel internal photoemission in manganite/ZnO heterostructure显示文摘A novel photovoltaic phenomenon of internal photoemission was found in a low cost manganite La0.62Ca0.29K 0.09MnO3 (LCKMO)/zinc oxide (ZnO) heterojunction bilayers grown on ITO substrate by pulsed laser deposition (PLD) at relative low growth temperature. The heterostructure ITO/LCKMO/ZnO/Al exhibits reproducible rectifying characteristics and light current under continuous laser irradiation of = 325 nm. We report here the influence of LCKMO/ZnO bilayers' thickness on the electrical and photoelectric properties of the heterostructure at room temperature. The power conversion efficiency (PCE) is achieved when the LCKMO and ZnO layers are thin enough or the full space charge layer is sufficient. We obtained the maximum value of PCE of 0.0145% when the thicknesses of LCKMO and ZnO layers are 25 and 150 nm, respectively. The open circuit voltage is 0.04 V under this condition due to the internal photoemission. | ZHANG JiaQi HUANG KeKe SI WenZhe WU XiaoFeng CHENG Gang FENG ShouHua | 2013 | Science China Chemistry2013,56,5: | 2 |

| 16 | Oxygen vacancy engineering of calcium cobaltate:A nitrogen fixation electrocatalyst at ambient condition in neutral electrolyte显示文摘In order to sustainably transform N2 to ammonia(NRR)using electrocatalysts under mild ambient condition,it is urgent to design and develop non-nobel metal nanocatalysts that are inexpensive and suitable for mass-production.Herein,a calcium metalate catalyst CaCoO_(x)with oxygen vacancies was synthesized and used as an electrocatalyst for NRR for the first time,whose morphology can be controlled by the calcination temperature and the heating rate.Under the optimal conditions,the CaCoO_(x)catalyst achieved the yield of nitrogen conversion to ammonia of 16.25μg·h^(-1)·mg_(cat.)^(-1)at the potential of-0.3 V relative to the reversible hydrogen electrode(RHE)with a Faraday efficiency of 20.51%.The electrocatalyst showed good stability even after 12 times recyclability under environmental conditions and neutral electrolyte.Later,the electrocatalytic nitrogen reduction performance of CaFeO_(x),CaNiO_(x),CaCuO_(x)was investigated.These earth-rich transition metals also exhibited certain NRR electrocatalytic capabilities,which provided a door for further development of inexpensive and easily available transition metal as nitrogen reduction electrocatalysts. | Xinyu Chen Ke Li Xiaoxuan Yang Jiaqi Lv Sai Sun Siqi Li Dongming Cheng Bo Li Yang-Guang Li Hong-Ying Zang | 2021 | Nano Research2021,14,2: | 2 |

| 18 | New Maikhanellid Shells and Siphogonuchitid Spicule Bundles from the Cambrian Fortunian Stage of South China显示文摘Maikhanellids are a distinct group of Cambrian Fortunian small shelly fossils by the capshaped profiles and scaly shell ornamentation.According to the individual shell shape and ornamentation feature types of 50 maikhanellids fossils which were collected from Xixiang botia,we confirmed the family Maikhanellidae content of six genera,which are Maikhanella,Ramenta,Purella,Ramentoides,Yunnannopleura and Mediata.Unlike the halkieriid animals whose shells and spicules are articulated on different body parts,maikhanellids were presumably yielded by siphogonuchitid spicules penetrating the intermediate matrix(the 'spicule shell' hypothesis),and this is the reason that some researchers treated maikhanellids and co-occurring siphogonuchitids as synonyms.The affinities of Maikhanellids and siphogonuchitids remain debatable.Here,we report three dimensionally phosphatized maikhanellid shells and siphogonuchitid spicule bundles from the Cambrian Fortunian small shell faunas of South China.They differ from all the previously reported maikhanellids and siphogonuchitids,and may represent new types.The intact and smooth surface underneath the partially preserved scales of the shells challenges the 'spicule-shell' hypothesis.The present siphogonuchitid spicules differ from the maikhanellid scales in size,morphology,and.arrangement pattern,thus the spicules might not be derived from the shells.Whether the shells and spicule bundles were articulated on different body parts of the same animals remains unknown. | LIU Yunhuan ZHANG Yanan SHAO Tiequan TANG Hanhua JIANG Kaituo WANG Qi CHEN Cheng DONG Junyan LIANG Yongchun DAI Jun XUE Jiaqi | 2016 | Acta Geologica Sinica(English Edition)2016,90,5: | 2 |

| 20 | Plant Selection of Constructed Wetlands for Treatment of Piggery Wastewater显示文摘Piggery wastewater contains high concentrations of organic matter and ammonia nitrogen,and it is difficult to treat it and make the discharged wastewater to meet the standard. Since the treatment of piggery wastewater treated under anaerobic conditions by traditional aerobic methods requires large investment,high running expense and strict management,breeding enterprises could hardly accept the technique. According to the characteristics of piggery wastewater,Pennisetum sp. + Rumex acetosa Linn and Populus + Nerium oleander can be planted in constructed wetlands to treat piggery wastewater,which can improve the treatment effect of piggery wastewater by constructed wetlands,solve the difficulty of wastewater treatment in winter,and bring obvious economic benefit. | Ao Ziqiang Zhang Jie Peng Guiqun Fu Jiaqi Jiang Cheng Xiong Jihai | 2017 | Meteorological and Environmental Research2017,8,2: | 2 |
