| 3 | The levels, sources and reactivity of volatile organic compounds in a typical urban area of Northeast China显示文摘Air concentrations of volatile organic compounds(VOCs) were continually measured at a monitoring site in Shenyang from 20 August to 16 September 2017. The average concentrations of alkanes, alkenes, aromatics and carbonyls were 28.54, 6.30, 5.59 and9.78 ppbv, respectively. Seven sources were identified by the Positive Matrix Factorization model based on the measurement data of VOCs and CO. Vehicle exhaust contributed the most(36.15%) to the total propene-equivalent concentration of the measured VOCs,followed by combustion emission(16.92%), vegetation emission and secondary formation(14.33%), solvent usage(10.59%), petrochemical industry emission(9.89%), petrol evaporation(6.28%), and liquefied petroleum gas(LPG) usage(5.84%). Vehicle exhaust, solvent usage and combustion emission were found to be the top three VOC sources for O_3 formation potential, accounting for 34.52%, 16.55% and 11.94%, respectively. The diurnal variation of the total VOCs from each source could be well explained by their emission characteristics,e.g., the two peaks of VOC concentrations from LPG usage were in line with the cooking times for breakfast and lunch. Wind rose plots of the VOCs from each source could reveal the possible distribution of the sources around the monitoring site. The O_3 pollution episodes during the measurement period were found to be coincident with the elevation of VOCs, which was mainly due to the air parcel from the southeast direction where petrochemical industry emission was found to be dominant, suggesting that the petrochemical industry emission from the southeast was probably a significant cause of O_3 pollution in Shenyang. | Zhuobiao Ma Chengtang Liu Chenglong Zhang Pengfei Liu Can Ye Chaoyang Xue Di Zhao Jichen Sun Yiming Du Fahe Chai Yujing Mu | 2019 | Journal of Environmental Sciences2019，31，5： | 12 |
| 4 | The origin and distribution of natural gas in the frontal uplift area of the Kuqa depression,Tarim Basin显示文摘The frontal uplift of the Kuqa depression is an important oil and gas producing area. In this study, the distribution and origin of natural gas were discussed based on natural gas components and isotope data. The main components of natural gas were hydrocarbons with relatively high contents of C2+ component. Most gases were derived from terrestrial source rocks, and some came from marine rocks. The contents of non-hydrocarbon gases were high in the central part of the frontal uplift area and low in the two terminals. The distribution of oil composition was similar to that of natural gas, which was mainly controlled by the types of source rocks. Dry coefficient and maturity of natural gas in the frontal uplift were lower than those of gas in the Kelasu tectonic belt of the Kuqa depression, which was mainly affected by the difference of tectonic movements in both areas. In the frontal uplift, the traps were formed in the early stage and could capture the early formed oil and gas, and structural adjustment was slight in later stages, so the oil and gas could be effectively preserved. Multiperiodic oil and gas filling led to the complex distribution of natural gas. | CUI Jie ZHU Guangyou ZHANG Bin SU Jin LU Yuhong MA Chenglong | 2010 | Chinese Journal Of Geochemistry2010，29，3： | 5 |
| 5 | Intelligent metasurface imager and recognizer显示文摘There is an increasing need to remotely monitor people in daily life using radio-frequency probe signals.However,conventional systems can hardly be deployed in real-world settings since they typically require objects to either deliberately cooperate or carry a wireless active device or identification tag.To accomplish complicated successive tasks using a single device in real time,we propose the simultaneous use of a smart metasurface imager and recognizer,empowered by a network of artificial neural networks(ANNs)for adaptively controlling data flow.Here,three ANNs are employed in an integrated hierarchy,transforming measured microwave data into images of the whole human body,classifying specifically designated spots(hand and chest)within the whole image,and recognizing human hand signs instantly at a Wi-Fi frequency of 2.4 GHz.Instantaneous in situ full-scene imaging and adaptive recognition of hand signs and vital signs of multiple non-cooperative people were experimentally demonstrated.We also show that the proposed intelligent metasurface system works well even when it is passively excited by stray Wi-Fi signals that ubiquitously exist in our daily lives.The reported strategy could open up a new avenue for future smart cities,smart homes,human-device interaction interfaces,health monitoring,and safety screening free of visual privacy issues. | Lianlin Li Ya Shuang Qian Ma Haoyang Li Hanting Zhao Menglin Wei Che Liu Chenglong Hao Cheng-Wei Qiu Tie Jun Cui | 2019 | Light(Science & Applications)2019，8，1： | 5 |
| 6 | Anisotropic corrosion resistance of TiC reinforced Ni-based composites fabricated by selective laser melting显示文摘Electrochemical measurements on three planes of TiC/Inconel 718 composites fabricated by selective laser melting(SLM) were performed to study the corrosion property. The results showed that the YZplane with dense and fine columnar structures possessed high microhardness and superior corrosion resistance in 3.5 wt% NaCl solution. For the XZ-plane, a decreased anti-corrosion property was observed owing to its inhomogeneous microstructures. While the XY-plane with large irregular pores and clustered ring-like structures was more susceptible to corrosion compared with the other two planes. Comparative analysis suggested that the anisotropic corrosion behaviors were significantly dependent on the surface defects, microstructure characteristics and added reinforcements. | Hongmei Zhang Dongdong Gu Lixia Xi Han Zhang Mujian Xia Chenglong Ma | 2019 | Journal of Materials Science & Technology2019，35，6： | 4 |
| 7 | An insight into failure mechanism of NASICON-structured Na3V2(PO4)3 in hybrid aqueous rechargeable battery显示文摘NASICON (Na-super-ionic-conductors)-structured materials have attracted extensive research interest due to their great application potential in secondary batteries. However, the mechanism of capacity fading for NASICON-structured electrode materials has been rarely studied. In this paper, we synthesized the NASICON-structured Na3V2(PO4)3/C composite by simple sol-gel and high-temperature solid-phase method and investigated its electrochemical performance in Na-Zn hybrid aqueous rechargeable batteries. After characterizing the structure, morphology and composition variations as well as the interfacial resistance changes of Na3V2(PO4)3/C cathode during cycling, we propose a mechanical and interfacial degradation mechanism for capacity fading of NASICON-structured Na3V2(PO4)3/C in Na-Zn hybrid aqueous rechargeable batteries. This work will shed light on enhancing the mechanical and in terfacial stability of NASICON-structured Na3V2(PO4)3/C in Na-Zn hybrid aqueous rechargeable batteries. | Xinxin Zhang Jun Ma Pu Hu Bingbing Chen Chenglong Lu Xinhong Zhou Pengxian Han Lihua Chen Guanglei Cui | 2019 | Journal of Energy Chemistry2019，28，5： | 3 |

| 10 | Thermodynamics of Molten Pool Predicted by Computational Fluid Dynamics in Selective Laser Melting of Ti6Al4V:Surface Morphology Evolution and Densification Behavior显示文摘The three-dimensional physical model of the randomly packed powder material irradiated by the laser beam was established,taking into account the transformation of the material phase,the melt spreading and the interaction of the free surface of the molten pool and the recoiling pressure caused by the material evaporation during the selective laser melting.Influence of the processing parameters on the thermal behavior,the material evaporation,the surface morphology and the densification behavior in the connection region of the molten pool and the substrate was studied.It was shown that the powder material underwent the transformation from the partial melting state to the complete melting state and finally to the overheating state with the applied laser energy density increasing from 167 J/mm^(3) to 417 J/mm^(3).Therefore,the solidified track ranged from the discontinuous tracks with the rough surface to the continuous tracks with residual porosities,then to the continuous and dense tracks and terminally to the fluctuated tracks with the increase in the laser energy density.Meanwhile,the laser energy effect depth was maintained the positive relationship with the laser energy density.The vortex velocity obtained in the free surface of the molten pool towards to the rear region in the opposite laser scan direction promoted the melt convection to the edge region of the molten pool as the laser energy density was higher than 277 J/mm^(3),demonstrating the efficient energy dissipation from the center of the irradiation region to the whole part of the molten pool and the attendant production of the sufficient melt volume.Therefore,the efficient spreading of the molten pool and the metallurgical bonding ability of the melt with the substrate was obtained at the optimized laser energy density of 277 J/mm^(3).However,the severe material evaporation would take place as the melt was overheated,resulting in the formation of the residual pores and poor surface quality. | Donghua Dai Dongdong Gu Qing Ge Chenglong Ma Xinyu Shi Han Zhang | 2020 | Computer Modeling in Engineering & Sciences2020，，9： | 1 |
| 11 | Shear viscosity to entropy density ratio in BUU transport model显示文摘Shear viscosity (η) is a basic transport coefficient of the medium.In this work,we calculate shear viscosity to entropy density ratio (η/S) of an equilibrated system in intermediate energy heavy ion collisions within the framework of the Boltzmann-Uehling-Uhlenbeck model (BUU) model.After the equilibration of Au + Au system at central collision in a fixed volume is reached,temperature,pressure and energy density are extracted by the phase space information and then η/S is calculated using the Green-Kubo formulas.The results show that η/S drops with the incident energy and its value is not so drastically different from the RHIC results. | LI Shaoxin FANG Deqing MA Yugang ZHOU Chenglong | 2011 | Nuclear Science and Techniques2011，22，4： | 1 |
| 12 | Exogenously applied oxalic acid assists in the phytoremediation of Mn by Polygonum pubescens Blume cultivated in three Mn-contaminated soils显示文摘The current study evaluated the effects of oxalic acid(OA)application on the growth and Mn phytoremediation efficiency of Polygonum pubescens Blume cultivated in three different manganese(Mn)-contaminated soils sampled from an unexplored area(US),an explored area(ES)and a tailing area(TS)of the Ertang Mn mine,South China.The supplied levels of OA were 0(control),1(low level),3(medium level),and 9(high level)mmol/kg,referred to as CK,OA1,OA3 and OA9,respectively.The results revealed that the average water-extractable Mn concentrations US,ES and TS amended with OA increased by 214.13,363.77 and 266.85%,respectively.All OA supply levels increased plant growth and Mn concentrations in US.The low OA supply level increased plant growth in ES and TS;however,contrasting results were found for the medium and high OA supply levels.Plant Mn concentrations and total Mn increased in ES and TS in response to all OA supply levels.Total Mn in the aerial parts increased by 81.18,44.17 and 83.17%in US,ES and TS,respectively;the corresponding percentages for the whole plants were 81.53,108.98 and 77.91%,respectively.The rate of·O_(2)^(−)production and malondialdehyde(MDA)concentrations increased in response to OA amendment,especially the medium and high OA supply levels in ES and TS.In general,antioxidant enzymes might play a vital role in alleviating Mn stress in plants cultivated in US,while non-enzymatic antioxidants might be the main factor for plants cultivated in ES and TS. | Kehui Liu Jie Xu Chenglong Dai Chunming Li Yi Li Jiangming Ma Fangming Yu | 2021 | Frontiers of Environmental Science & Engineering2021，15，5： | 1 |
| 13 | Poly-Si films with low aluminum dopant containing by aluminum-induced crystallization显示文摘Typically, highly p-doped (2×10 18 cm -3 ) poly-Si films fabricated by the aluminum induced layer exchange (ALILE) process are not suitable for solar cell absorber layers. In this paper, the fabrication of high-quality, continuous polycrystalline silicon (poly-Si) films with lower doping concentrations (2×10 16 cm -3 ) using aluminum-induced crystallization (AIC) is reported. Secondary-ion-mass spectroscopy (SIMS) results showed that annealing at different temperature profiles leads to a variety of Al concentrations. Hall Effect measurements revealed that Al dopant concentration depends on the annealing temperature and temperature profile. Raman spectral analysis indicated that samples prepared via AIC contain some regions with small grains. | WANG ChengLong 1,2 , FAN DuoWang 1,2 , WANG ChengBin 2 , GENG ZhongRong 2 , MA HaiLin 2 & MIAO ShuFan 1 1 National Engineering Research Center for Technology and Equipment of Green Coating, Lanzhou Jiaotong University, Lanzhou 730070, China 2 MOE Key Laboratory of Opto-electronic Technology and Intelligence Control, Lanzhou Jiaotong University, Lanzhou 730070, China Received January 8, 2009 accepted February 2, 2009 | 2010 | Science China(Physics,Mechanics & Astronomy)2010，53，1： | 1 |
| 14 | Laser Powder Bed Fusion-built Ti6Al4V Bone Scaffolds Composed of Sheet and Strut-based Porous Structures: Morphology, Mechanical Properties, and Biocompatibility显示文摘Laser powder bed fusion(L-PBF)-built triply periodic minimal surface(TPMS)structures are designed by implicit functions and are endowed with superior characteristics,such as adjustable mechanical properties and light-weight features for bone repairing;thus,they are considered as potential candidates for bone scaffolds.Unfortunately,previous studies have mainly focused on different TPMS structures.The fundamental understanding of the differences between strut and sheet-based structures remains exclusive,where both were designed by one formula.This consequently hinders their practical applications.Herein,we compared the morphology,mechanical properties,and biocompatibility of sheet and strut-based structures.In particular,the different properties and in vivo bone repair effects of the two structures are uncovered.First,the morphology characteristics demonstrate that the manufacturing errors of sheet-based structures with diverse porosities are comparable,and semi-melting powders as well as the ball phenomenon are observed;in comparison,strut-based samples exhibit cracks and thickness shrinking.Second,the mechanical properties indicate that the sheet-based structures have a greater elastic modulus,energy absorption,and better repeatability compared to strut-based structures.Furthermore,layer-by-layer fracturing and diagonal shear failure modes are observed in strut-based and sheet-based structures,respectively.The in vivo experiment demonstrates enhanced bone tissues in the strut-based scaffold.This study significantly enriches our understanding of TPMS structures and provides significant insights in the design of bone scaffolds under various bone damaging conditions. | Shuai Ma Qian Tang Changbao Zhu Fuyou Wang Qixiang Feng Jun Song Rossitza Setchi Chenglong Ma Ran Tao | 2022 | Chinese Journal of Mechanical Engineering(Additive Manufacturing Frontiers)2022，1，4： | 0 |
| 15 | Novel Class of Additive Manufactured NiTi-Based Hierarchically Graded Chiral Structure with Low-force Compressive Actuation for Elastocaloric Heat Pumps显示文摘Elastocaloric refrigeration is the most promising green solid-state refrigeration technology to replace conventional vapor compression refrigeration.The development direction of the elastocaloric component that acts as a key part of the elastocaloric refrigeration system contains a large elastocaloric effect,low stress hysteresis,high heat exchange performance,and small driving loads.The first two indices can be realized by material modification;however,the last two are more dependent on a novel porous structure design.However,the conventional porous structure is confronted with some critical challenges,including inhomogeneous stress,a significant hysteresis area,and deformation instability under the alternating cyclic loading.In this study,a NiTi-based elastocaloric structure model with chirality feature and gradient design as innovative elements was presented,bio-inspired by the structure of the plant tendrils.A quantitative optimization for the NiTi-based elastocaloric structure was performed using the finite element analysis(FEA)method.Strain and martensite volume fraction(MVF)fields during the loading and unloading processes were predicted and evaluated.The simulated results indicated that increasing the thickness gradient g_(1) of the strip or decreasing the diameter gradient g_(2) of the structure was beneficial to achieving more homogeneous strain and martensite distribution,simultaneously with higher energy storage efficiency and specific surface area.In addition,these NiTi-based chiral structures with different structural parameters were fabricated by laser powder bed fusion(LPBF).At the optimized structure parameters of g_(1)=2 and g_(2)=1.11,the LPBF-fabricated NiTi-based chiral structure could achieve an adiabatic temperature change ΔT_(ad) of 2.3 K,driving force of as low as 149.11 N,and|ΔT_(ad)/F|of as high as 15.42 K/kN at a recoverable compressive strain of 10%. | Xin Peng Luhao Yuan Donghua Dai Yu Liu Dongya Li Dehui Zhu Ziyu Fang Chenglong Ma Dongdong Gu Meiping Wu | 2023 | Chinese Journal of Mechanical Engineering(Additive Manufacturing Frontiers)2023，2，2： | 0 |
| 16 | Jujube witches’ broom phytoplasmas inhibit ZjBRC1-mediated abscisic acid metabolism to induce shoot proliferation显示文摘Jujube witches’broom(JWB)phytoplasmas parasitize the sieve tubes of diseased phloem and cause an excessive proliferation of axillary shoots from dormant lateral buds to favour their transmission.In previous research,two JWB effectors,SJP1 and SJP2,were identified to induce lateral bud outgrowth by disrupting ZjBRC1-mediated auxin flux.However,the pathogenesis of JWB disease remains largely unknown.Here,tissue-specific transcriptional reprogramming was examined to gain insight into the genetic mechanisms acting inside jujube lateral buds under JWB phytoplasma infection.JWB phytoplasmas modulated a series of plant signalling networks involved in lateral bud development and defence,including auxin,abscisic acid(ABA),ethylene,jasmonic acid,and salicylic acid.JWB-induced bud outgrowth was accompanied by downregulation of ABA synthesis within lateral buds.ABA application rescued the bushy appearances of transgenic Arabidopsis overexpressing SJP1 and SJP2 in Col-0 and ZjBRC1 in the brc1-2 mutant.Furthermore,the expression of ZjBRC1 and ABA-related genes ZjHB40 and ZjNCED3 was negatively correlated with lateral main bud outgrowth in decapitated healthy jujube.Molecular evidence showed that ZjBRC1 interacted with ZjBRC2 via its N-terminus to activate ZjHB40 and ZjNCED3 expression and ABA accumulation in transgenic jujube calli.In addition,ZjBRC1 widely regulated differentially expressed genes related to ABA homeostasis and ABA signalling,especially by binding to and suppressing ABA receptors.Therefore,these results suggest that JWB phytoplasmas hijack the ZjBRC1-mediated ABA pathways to stimulate lateral bud outgrowth and expansion,providing a strategy to engineer plants resistant to JWB phytoplasma disease and regulate woody plant architecture to promote crop yield and quality. | Fuli Ma Shanqi Zhang Yu Yao Mengting Chen Ning Zhang Mingsheng Deng Wei Chen Chi Ma Xinyue Zhang Chenglong Guo Xiang Huang Zhenyuan Zhang Yamei Li Tingyi Li Junyong Zhou Qibao Sun Jun Sun | 2023 | Horticulture Research2023，10，9： | 0 |
| 17 | Effects of Latin,Rock and African Percussion Music on Protein and Energy Metabolism in Cow显示文摘This study was conducted to study the effects of Latin,rock,and African percussion music on milk production performance in cow. 72 Holstein cows with similar milk yield,age,parity and lactation were randomly divided into four groups,namely the Latin music group,rock music group,African percussion music group and control group,each 18 cows. The pretrial period lasted for 7 d,and the formal trial period was 60 d. The music began to be played in test group from pretrial period,while the control group received routine feeding. Milk yield was measured every 20 d,and milk sample was collected once. The results showed that African percussion music could increase the contents of GLB,ALT and LDH in the serum of cow,and reduce the milk yield of cow. Rock music would increase the serum LDH content in cow and reduce the milk yield of cow. | Wang Donghai Ma Xiaoyan Wu Yufei Luo Chenglong Yu Xiong | 2018 | Meteorological and Environmental Research2018，9，2： | 0 |
| 18 | Characteristics of gravity anomalies and tectonic analysis of Enderby Land in East Antarctica and its adjacent areas显示文摘Enderby Land in East Antarctica and its adjacent areas,which are closely related to the Indian Plate in their geological evolution,have become one of the key zones for studies on how the Antarctic continent evolves.Based on the isostasy and flexure theories of the lithosphere and using the CRUST1.0 model as the depth constraint,this paper uses the gravity field model EIGEN-6C4 and topographic data to calculate the isostatic gravity anomalies of Enderby Land and its adjacent areas.Then,the crustal thickness of the study area is calculated,and three comprehensive geophysical interpretation profiles that vertically span the study area are plotted.The results show that the flexural isostatic gravity anomalies in Enderby Land and its adjacent areas are closely related to the regional tectonic setting,and the anomalies in different regions differ substantially,ranging from−50×10^(−5)m/s^(2)to 85×10^(−5)m/s^(2).A zone of high isostatic gravity anomalies(30×10^(−5)−80×10^(−5)m/s^(2))is distributed outside the Cooperation Sea and Queen Maud Land,which may be plate remnants generated by early rifting.Except for the Kerguelen Plateau,which was formed by a hotspot and has a crustal thickness of 15 km,the thickness of the oceanic crust in other parts of the study area changes slightly by approximately 4–9 km,with the thinnest part being in Enderby Basin.The thickness of the inland crust along the coastline increases with the elevation,with the maximum thickness reaching 34 km.The isostatic gravity anomalies corresponding to the zone of high magnetic anomalies along the continental margin of Queen Maud Land are negative and small,with an isostatic adjustment trend indicating Moho surface uplift,and those on the edge of central Enderby Land are near zero,approaching the isostatic state,which may be caused by the magmatism at the early stage of rifting.The continental-oceanic boundary should be close to the contour line of the crustal thickness 10–12 km on the outer edge of the coastline. | Long Ma Chenguang Liu An Yang Baohua Liu Chenglong Xia | 2023 | Acta Oceanologica Sinica2023，42，2： | 0 |
| 19 | Tectonic implications of the subduction of the Kyushu-Palau Ridge beneath the Kyushu,southwest Japan显示文摘The Kyushu-Palau Ridge(KPR),a remnant arc on the Philippine Sea Plate(PSP),is subducting beneath the Kyushu,southwest Japan.Influenced by the subducting KPR,the Kyushu subduction zone corresponding to the KPR is significantly different from Shikoku subduction zone in terms of gravity anomalies,seismicity,the stress state,and the subducting slab morphology.Significant negative free-air and Bouguer gravity anomalies are observed in a prolonged area of KPR,southeast of the Miyazaki Plain,indicating that this is where KPR overlaps the overriding plate.The gravity anomaly in this area is much lower than that in other areas where the inferred KPR extends,suggesting that the subduction of the buoyant KPR may cause the lower mantle density to decrease.More earthquakes have occurred in Hyuga-nada region where the KPR subducts than in Shikoku forearc and other areas in the Kyushu forearc,indicating that the subduction of the KPR enhances the local coupling between the subducting and overriding plates.The centroid moment tensor(CMT)mechanism of earthquakes shows that stress is concentrated in the accumulated crust beneath the Kyushu forearc corresponding to the KPR,and the shallow thrusting events in the obducting plate are caused by the KPR subduction.The buoyant KPR,with a large volume of low-density sediments,was responsible for the differences of the subduction depth and dip angle of the subducting Philippine Sea(PS)slab between northern Kyushu and Shikoku.The seismic gaps and the sudden change of the dipping angle of the subducting PS slab indicate that slab tear may have occurred along the west side of the KPR beneath southwest Kyushu.A two-tear model was proposed,and the subduction of the buoyant KPR was believed to play an important role in the slab tear. | Chenglong Xia Yanpeng Zheng Baohua Liu Qingfeng Hua Long Ma Xianfeng Li Qiuhong Xie | 2021 | Acta Oceanologica Sinica2021，40，3： | 0 |
| 20 | A novel on-tissue cycloaddition reagent for mass spectrometry imaging of lipid C=C position isomers in biological tissues显示文摘Application of matrix-assisted laser desorption/ionization mass spectrometry imaging(MALDI-MSI) to investigate the spatiotemporal alterations of lipids in biological tissues has brought many significant results.However, the presence of structural isomers varying in C=C double bond(DB) locations makes isomerresolved MSI an urgent need. Herein, we introduce a new type of light-driven on-tissue [2 + 2] cycloaddition reaction coupled with MALDI-MS/MS imaging to identify lipid DB position isomers and their spatial signatures in biological tissues. 3-Benzoylpyridine was introduced as a novel derivatization reagent, and it exhibited great reactivity toward lipid C=C bond to form oxetanes under both ultraviolet light and visible light irradiation. With this approach, DB position isomers of lipids were imaged with highly differential levels in distinct regions of rat brain, providing an accurate and spatially resolved approach to study tissue lipidomics. | Chenglong Sun Chunxia Ma Lili Li Yuhao Han Daijie Wang Xiao Wan | 2022 | Chinese Chemical Letters2022，33，4： | 0 |
