| 1 | Diagnostic Study on the Structural Characteristics of a Typical Mei-yu Front System and Its Maintenance Mechanism显示文摘In this paper, a typical mei-yu front process with heavy rainfall from June 12 to 15 in 1998 is analyzed. The results show that the mei-yu front is a front system which consists of an iso-θe dense area with strong horizontal gradient, a deep-convective cloud tower band, a passageway transporting warm and moist air ?ow from the summer monsoon surge in the mid and low levels to the south of the mei-yu front, and a migrating synoptic scale trough to the north of the mei-yu front, which transports cold and dry air southward in the mid and upper levels. The maintenance of the mei-yu front is realized by: (1) is a positive feedback between the moist physical process enhancing frontogenesis and the development of the strong convective system in front of the mei-yu front; (2) the sustaining system to the north of the mei-yu front which is a migrating synoptic scale trough transporting cold and dry air to the mei-yu front and positive vorticity to the mesoscale system in front of the mei-yu front. | JIANG Jianying(蒋建莹) NI Yunqi(倪允琪) | 2004 | Advances in Atmospheric Sciences2004，21，5： | 22 |
| 2 | Reactive adsorption of thiophene on Ni/ZnO adsorbent:Effect of ZnO textural structure on the desulfurization activity显示文摘To better understand the nature of reactive adsorption of thiophene on Ni/ZnO adsorbent,the effect of ZnO textural structure on the desulfurization activity was investigated.ZnO materials were synthesized by low-temperature solid-state reaction and the corresponding Ni/ZnO adsorbents were prepared by incipient impregnation method.The analysis results showed that the crystalline sizes of ZnO as-synthesized as well as the BET surface areas varied obviously with the calcination temperature.The activity evaluations indicated that the Ni/ZnO adsorbents prepared with ZnO possessed a favorable textural structure as active component exhibited good activity of removing thiophene.The evolutions of the main crystalline phases of Ni/ZnO adsorbents before and after reaction confirmed that ZnO played a crucial role in taking up S element and converting it into ZnS in the reactive adsorption process.It was concluded that ZnO with larger surface area and smaller crystal particles resulted in better desulfurization activity,which may be the main reason for the different activities of the Ni/ZnO adsorbents prepared with ZnO calcined at different temperatures. | Jingcheng Zhang Yunqi Liu Shuang Tian Yongming Chai Chenguang Liu | 2010 | Journal of Natural Gas Chemistry2010，19，3： | 13 |
| 3 | Reaction environment self-modification on low-coordination Ni^(2+)octahedra atomic interface for superior electrocatalytic overall water splitting显示文摘Large scale synthesis of high-efficiency bifunctional electrocatalyst based on cost-effective and earth-abundant transition metal for overall water splitting in the alkaline environment is indispensable for renewable energy conversion.In this regard,meticulous design of active sites and probing their catalytic mechanism on both cathode and anode with different reaction environment at molecular-scale are vitally necessary.Herein,a coordination environment inheriting strategy is presented for designing low-coordination Ni^(2+)octahedra(L-Ni-8)atomic interface at a high concentration(4.6 at.%).Advanced spectroscopic techniques and theoretical calculations reveal that the self-matching electron delocalization and localization state at L-Ni-8 atomic interface enable an ideal reaction environment at both cathode and anode.To improve the efficiency of using the self-modification reaction environment at L-Ni-8,all of the structural features,including high atom economy,mass transfer,and electron transfer,are integrated together from atomic-scale to macro-scale.At high current density of 500 mA/cm2,the samples synthesized at gram-scale can deliver low hydrogen evolution reaction(HER)and oxygen evolution reaction(OER)overpotentials of 262 and 348 mV,respectively. | Kaian Sun Lei Zhao Lingyou Zeng Shoujie Liu Houyu Zhu Yanpeng Li Zheng Chen Zewen Zhuang Zhaoling Li Zhi Liu Dongwei Cao Jinchong Zhao Yunqi Liu Yuan Pan Chen Chen | 2020 | Nano Research2020，13，11： | 12 |
| 4 | Identification of the deposited layers in landslides reservoir and investigation of the sediment yields during the later sixteenth century on the Hill Loess Plateau,China显示文摘There are many sediment trapping reservoirs in the Hill Loess Plateau.The Huangtuwa small catchment is selected as a research field where samples were collected in a sediment deposit profile with a vertical length of 12.73 m.By the variation of fine particle content and pollen concentration,54 flood couples were identified.Taking the freeze-thawing disturbed texture as the sign of the latest flood couple in a year,it is ascertained that those 54 floods should happen in 31 years.Using pyramid volume calculation formula,the sediment yields of flood ranged between 716―30376 t·km-2.The average sediment yield was 7106 t·km-2.The annual sediment yields varied between 968―55579 t·(km2·a) -1,and the average value is 12629 t·(km2·a) -1.Compared with the modern annual sediment discharge of the Huaining River,the erosion rate in the Huangtuwa region 450 years ago was similar to the modern erosion rate.In the period from the 27th year to the 31st year,the average annual sediment yield increased sharply to 31309 t·(km2·a) -1.It implied that re-reclamation of the abandoned land in the catchment since the landslide disaster,where vegetation had rehabilitated already,caused very severe soil erosion in the catchment. | LONG Yi ZHANG XinBao LI Min LI Mian ZHANG YunQi | 2008 | Chinese Science Bulletin2008，53，24： | 9 |
| 5 | Molecular, Functional, and Structural Imaging of Major Depressive Disorder显示文摘Major depressive disorder(MDD) is a significant cause of morbidity and mortality worldwide,correlating with genetic susceptibility and environmental risk factors.Molecular,functional,and structural imaging approaches have been increasingly used to detect neurobiological changes,analyze neurochemical correlates,and parse pathophysiological mechanisms underlying MDD.We reviewed recent neuroimaging publications on MDD in terms of molecular,functional,and structural alterations as detected mainly by magnetic resonance imaging(MRI) and positron emission tomography.Altered structure and function of brain regions involved in the cognitive control of affective state have been demonstrated.An abnormal default mode network,as revealed by resting-state functional MRI,is likely associated with aberrant metabolicand serotonergic function revealed by radionuclide imaging.Further multi-modal investigations are essential to clarify the characteristics of the cortical network and serotonergic system associated with behavioral and genetic variations in MDD. | Kai Zhang Yunqi Zhu Yuankai Zhu Shuang Wu Hao Liu Wei Zhang Caiyun Xu Hong Zhang Takuya Hayashi Mei Tian | 2016 | Neuroscience Bulletin2016，32，3： | 9 |
| 6 | NiMo/Al_2O_3 catalyst containing nano-sized zeolite Y for deep hydrodesulfurization and hydrodenitrogenation of diesel显示文摘Two mixed-matrix NiMo/Al2O3 catalysts containing nano-and micro-sized zeolite Y have been prepared to explore the size effect of zeolite Y particle on the hydrodesulfurization(HDS)and hydrodenitrogenation(HDN)activities of fluid catalytic cracking(FCC)diesel.They were characterized by SEM,BET,XRD,H2-TPR,NH3-TPD and HRTEM.The results show that the catalyst containing nano-sized zeolite Y possesses larger average pore diameter,higher pore volume,weaker and lesser acid sites,more easily reducible metal phases,shorter MoS2 slabs and more slab layers than the catalyst containing micro-sized zeolite Y.The catalysts were also evaluated with a high-pressure fixed-bed reactor using real FCC diesel as feed.The results display that the catalyst containing nano-sized zeolite Y bears higher HDS and HDN activities and exhibits higher relative rate constant for the removal of total sulfur or nitrogen than the one containing micro-sized zeolite. | Hailiang Yin Tongna Zhou Yunqi Liu Yongming Chai Chenguang Liu | 2011 | Journal of Natural Gas Chemistry2011，20，4： | 8 |
| 7 | Monolayer organic field-effect transistors显示文摘Monolayer organic field-effect transistors(OFETs) are attracting worldwide interest in device physics and novel applications due to their ultrathin active layer for two-dimensional charge transport. The monolayer films are generally prepared by thermal evaporation, the Langmuir technique or self-assembly process, etc., but their electrical performance is relatively lower than corresponding thick films. From 2011, the performance of monolayer OFETs has been boosted by using the monolayer molecular crystals(MMCs) as active channels, which opened up a new era for monolayer OFETs. In this review, recent progress of monolayer OFETs, including the preparation of monolayer films, their OFET performance and applications are summarized.Finally, perspectives of monolayer OFETs in the near future are also discussed. | Jie Liu Lang Jiang Wenping Hu Yunqi Liu Daoben Zhu | 2019 | Science China Chemistry2019，62，3： | 7 |
| 8 | Effect of preparation method on the bimetallic NiCu/SAPO-11 catalysts for the hydroisomerization of n-octane显示文摘The bimetallic NiCu/SAPO-11 catalysts were prepared by co-impregnation, sequential impregnation, coprecipitation, and mechanical mixing methods. Powder X-ray diffraction, nitrogen adsorption-desorption,temperature-programmed desorption of ammonia, transmission electron microscopy, temperatureprogrammed reduction of hydrogen, and X-ray photoelectron spectroscopy were used to characterize the physicochemical properties of the catalysts. The catalytic performance of the catalysts was assessed by the hydroisomerization of n-octane. Results indicated that the conversion of n-octane and selectivity to n-octane isomers were related to the preparation methods of the catalysts. The catalysts with Ni-Cu alloy effectively restrained the hydrogenolysis reaction that decreases the selectivity of isomerization. The catalyst prepared by the mechanical mixing of NiO and CuO hardly formed Ni-Cu alloy, showing obvious hydrogenolysis and low selectivity to n-octane isomers. The unbalance between the metal and acid sites resulted in the low conversion of n-octane and selectivity to n-octane isomers. Among all the catalysts,the catalyst prepared by the co-impregnation method exhibited high catalytic activity and selectivity to n-octane isomers. | Zhichao Yang Yunqi Liu Yanpeng Li Lingyou Zeng Zhi Liu Xueying Liu Chenguang Liu | 2019 | Journal of Energy Chemistry2019，28，1： | 7 |
| 9 | One-step synthesis of Fe-Ni hydroxide nanosheets derived from bimetallic foam for efficient electrocatalytic oxygen evolution and overall water splitting显示文摘The research of superior water oxidation electrodes is essential for the green energy in the form of hydrogen by way of electrolytic water splitting, and still remains challenging. Based upon dealloying foam, Fe-Ni hydroxide nanosheets network structure is designed on the surface of Fe-Ni alloy foam. The ratio of Ni/Fe elements was adjusted to realize the optimal catalytic activities for oxygen evolution reaction(OER) and hydrogen evolution reaction(HER). The obtained electrode of Fe-Ni hydroxide nanosheets/Fe-Ni alloy foam-60% Fe(FN LDH/FNF-60, 60 is the percentage of Fe content) possess low overpotential of 261 mV to reach 10 mA/cm^2, small Tafel slope(85.5 mV/dec), and superior long-term stability(remaining 10 mA/cm^2 for over 14 h without attenuation) toward OER in 1.0 mol/L KOH.Moreover, an alkaline water electrolyzer is constructed with the FN LDH/FNF-60 as anode and Ni(OH)_2/Fe-Ni alloy foam-25% Fe(Ni(OH)_2/FNF-25) as cathode, which displays superior electrolytic performance(affording 10 mA/cm^2 at 1.62 V) and lasting durability. | Lili Zeng Linjing Yang Jia Lu Jin Jia Jiayuan Yu Yunqie Deng Mingfei Shao Weijia Zhou | 2018 | Chinese Chemical Letters2018，29，12： | 7 |

| 11 | Stable isotope fractionation of chlorine during evaporation of brine from a saline lake显示文摘Brine from the saline Qarhan Lake was evaporated at 28±2°C in a clean environment.Two groups of experiments were conducted;one with complete separation of precipitate and brine at different stages of evaporation,and the other with continuous precipitation during the evaporation.Seventy-nine precipitate and brine samples were collected during the experiments,and the δ37 Cl values were determined using an improved thermal ionization mass spectrometry procedure for precise measurement of chlorine isotopes based on Cs2Cl+ ions.Based on the concentrations of Na+,K+,and Mg2+,evaporation was divided into three main precipitation stages as follows:halite dominant,carnallite dominant,and bischofite dominant.The δ37 Clsolid and δ37 Clliquid values of the precipitate and coexisting brine samples at different stages showed the following characteristics.The precipitates were enriched with 37 Cl relative to the coexisting brine samples,and the δ37 Cl of both the precipitate and brine samples decreased gradually during evaporation.The fractionation factors(αh) between halite and brine were the highest,followed by that(αc) between carnallite and brine,and then that(αb) between bischofite and brine.The αc and αb values of less than one,which indicate the precipitate is enriched in 35 Cl,were found when the evaporation process entered a new stage.However,the δ37 Cl values of carnallite,bischofite,and the coexisting brine samples decreased during evaporation.The residual brine is a 35 Cl reservoir.The experimental phenomena were consistent with the δ37 Cl values in saline deposits in the literature.δ37 Cl can be used as an indicator of brine evaporation processes,which is important in the exploration of sylvinite deposits. | LUO ChongGuang XIAO YingKai MA HaiZhou MA YunQi ZHANG YanLing HE MaoYong | 2012 | Chinese Science Bulletin2012，57，15： | 6 |
| 12 | Ultra-deep desulfurization by reactive adsorption desulfurization on copper-based catalysts显示文摘In this paper,a novel copper-based catalyst for FCC gasoline improving the ability of removal the sulfur and avoiding the loss of the octane number from olefin saturation by reactive adsorption desulfurization(RADS) was investigated.The series of Cu/Zn O-Al_2 O_3 catalysts were characterized by X-ray powder diffraction(XRD),N_2 adsorption analysis and temperature-programmed reduction(TPR) studies,X-ray photoelectron spectroscopy(XPS),scanning electron microscope(SEM) and transmission electron microscopy(TEM).The experiment results showed that the catalysts had an optimum desulfurization ability with copper loading 6 wt%,which the sulfur contents of product decreased less than 10 μg/g and olefin contents decreased from 16.19% to 14.14% for the long period operation.The appropriate Cu loading content could lead to the high active and low apparent activation energy(E_a).Therefore,the Cu-based catalyst may become a novel catalyst for second-generation for reactive adsorption desulfurization,which achieves the high desulfurization active and low olefins saturation to satisfy the upgrading the product. | Yaqing Liu Hongying Wang Jinchong Zhao Yunqi Liu Chenguang Liu | 2019 | Journal of Energy Chemistry2019，28，2： | 6 |
| 13 | The Lyman-alpha Solar Telescope(LST) for the ASO-S mission——Ⅱ. design of LST显示文摘As one of the three payloads for the Advanced Space-based Solar Observatory(ASO-S)mission,the Lyman-alpha(Lyα)Solar Telescope(LST)is composed of three instruments:a Solar Corona Imager(SCI),a LyαSolar Disk Imager(SDI)and a full-disk White-light Solar Telescope(WST).When working in-orbit,LST will simultaneously perform high-resolution imaging observations of all regions from the solar disk to the inner corona up to 2.5 R⊙(R⊙stands for the mean solar radius)with a spatial resolution of 4.8′′and 1.2′′for coronal and disk observations,respectively,and a temporal resolution of 30–120 s and 1–120 s for coronal and disk observations,respectively.The maximum exposure time can be up to20 s due to precise pointing and image stabilization function.Among the three telescopes of LST,SCI is a dual-waveband coronagraph simultaneously and independently observing the inner corona in the HI Lyα(121.6±10 nm)line and white light(WL)(700±40 nm)wavebands by using a narrowband Lyαbeam splitter and has a field of view(FOV)from 1.1 to 2.5 R⊙.The stray-light suppression level can attain<10^-6 B⊙(B⊙is the mean brightness of the solar disk)at 1.1 R⊙and≤5×10^-8 B⊙at 2.5 R⊙.SDI and WST are solar disk imagers working in the Lyαline and 360.0 nm wavebands,respectively,which adopt an off-axis two-mirror reflective structure with an FOV up to 1.2 R⊙,covering the inner coronal edge area and relating to coronal imaging.We present the up-to-date design for the LST payload. | Bo Chen Hui Li Ke-Fei Song Quan-Feng Guo Pei-Jie Zhang Ling-Ping He Shuang Dai Xiao-Dong Wang Hai-Feng Wang Chun-Long Liu Hong-Ji Zhang Guang Zhang Yunqi Wang Shi-Jie Liu Hong-Xin Zhang Lei Liu Shi-Lei Mao Yang Liu Jia-Hao Peng Peng Wang Liang Sun Yang Liu Zhen-Wei Han Yan-Long Wang Kun Wu Guang-Xing Ding Peng Zhou Xin Zheng Ming-Yi Xia Qing-Wen Wu Jin-Jiang Xie Ya Chen Shu-Mei Song Hong Wang Bo Zhu Chang-Bo Chu Wen-Gang Yang Li Feng Yu Huang Wei-Qun Gan Ying Li Jing-Wei Li Lei Lu Jian-Chao Xue Bei-Li Ying Ming-Zhe Sun Cheng Zhu Wei-Min Bao Lei Deng Zeng-Shan Yin | 2019 | Research in Astronomy and Astrophysics2019，19，11： | 6 |
| 14 | Adaptive optical focusing through perturbed scattering media with a dynamic mutation algorithm显示文摘Optical imaging through or inside scattering media, such as multimode fiber and biological tissues, has a significant impact in biomedicine yet is considered challenging due to the strong scattering nature of light. In the past decade, promising progress has been made in the field, largely benefiting from the invention of iterative optical wavefront shaping, with which deep-tissue high-resolution optical focusing and hence imaging becomes possible. Most of the reported iterative algorithms can overcome small perturbations on the noise level but fail to effectively adapt beyond the noise level, e.g., sudden strong perturbations. Reoptimizations are usually needed for significant decorrelation to the medium since these algorithms heavily rely on the optimization performance in the previous iterations. Such ineffectiveness is probably due to the absence of a metric that can gauge the deviation of the instant wavefront from the optimum compensation based on the concurrently measured optical focusing.In this study, a square rule of binary-amplitude modulation, directly relating the measured focusing performance with the error in the optimized wavefront, is theoretically proved and experimentally validated. With this simple rule, it is feasible to quantify how many pixels on the spatial light modulator incorrectly modulate the wavefront for the instant status of the medium or the whole system. As an example of application, we propose a novel algorithm, the dynamic mutation algorithm, which has high adaptability against perturbations by probing how far the optimization has gone toward the theoretically optimal performance. The diminished focus of scattered light can be effectively recovered when perturbations to the medium cause a significant drop in the focusing performance, which no existing algorithms can achieve due to their inherent strong dependence on previous optimizations. With further improvement, the square rule and the new algorithm may boost or inspire many applications, such as high-resolution optical imaging and stimulation, in instable or dynamic scattering environments. | HUANHAO LI CHI MAN WOO TIANTING ZHONG ZHIPENG YU YUNQI LUO YUANJIN ZHENG XIN YANG HUI HUI PUXIANG LAI | 2021 | Photonics Research2021，9，2： | 6 |
| 15 | Fabrication of hierarchical porous ZnO and its performance in Ni/ZnO reactive-adsorption desulfurization显示文摘To investigate the effect of texture structure on the desulfurization performance in the Ni/ZnO reactive adsorption desulfurization(RADS) system,two kinds of ZnO porous materials with rod-shaped morphology were synthesized and their structure was characterized by X-ray diffraction(XRD),scanning electron microscopy(SEM),transmission electron microscopy(TEM),and N2 adsorption/desorption.The formation mechanisms of hierarchical porous ZnO(ZnO with meso and macro pores) were also studied.Their application performance was evaluated in the RADS process over Ni/ZnO absorbent.Due to the difference in structure between the two kinds of ZnO,the two ZnO based adsorbents showed different desulfurization activity. | Liu Yunqi She Nannan Zhao Jinchong Peng Tingting Liu Chenguang | 2013 | Petroleum Science2013，10，4： | 6 |
| 16 | Extraction of rare earth ions from phosphate leach solution using emulsion liquid membrane in concentrated nitric acid medium显示文摘It is very significant to recover rare earths(REs) from wet-process phosphoric acid, in terms of extraction rate and selectivity, the current carrier di(2-ethlhexly) phosphate(D2EHPA) out there is still inferior.Based on this question, our team modified D2EHPA to synthesize new extractants. This paper presents a comprehensive study on the extraction of rare earth ions(RE^(3+)) from phosphate leach solution using emulsion liquid membrane(ELM) in concentrated nitric acid medium. The ELM system is made up of(RO)_2P(O)OPh-COOH as carrier, polyisocrotyl succinimide(T154) as surfactant, sulfonated kerosene as diluent, phosphoric acid(H_3PO_4) as stripping solution. Different chemical parameters such as type and concentration of carrier, surfactant, stripping solution, volume ratio of oil phase to internal phase, and volume ratio of emulsion ratio to external phase were analyzed. The extraction of RE^(3+) was evaluated by the yield of extraction. In addition, the demulsification process was also investigated. The proposed method of ELM using(RO)_2P(O)OPh-COOH as carrier can be expected to provide an efficient, simplify operation, and facilitated method for extracting RE^(3+). | Qianlin Chen Xin Ma Xin Zhang Yunqi Liu Ming Yu | 2018 | Journal of Rare Earths2018，36，11： | 5 |
| 17 | Structure,rheology and electrospinning of zein and poly(ethylene oxide) in aqueous ethanol solutions显示文摘Electrospun fiber mats (EFM) integrated proteins and biocompatible polymers have been widely used as tissue scaffold, wound dressing and food packaging. The morphology of EFM has strong correlation with the structure and rheology of the solutions. We studied the structure and rheology of polyethylene oxide (PEO) and zein in 80% ethanol aqueous solutions and the resulted EFM. In solutions, zein with rod-like conformation tends to aggregate and form oligomer, the number of proteins in the oligomer spans from 2.5 to 55.2, while PEO always behaves like Gaussian chain in good solvent. Zein preferred to distribute along PEO chains in their mixed solutions, and the structures decomposed from small angle X-ray scattering have consistent relaxation spatial-temporal characteristics with rheological behaviors.Further, the aging of zein solutions enhanced shear thinning and resulted thicker fibers in EFM, which are attributed to the rod-like growth of zein aggregates. Aggregates in viscous media with long enough relaxation time are probably crucial for the formation of continuous electrospun fibers or ribbons. This study provides a clear correlation of the structure, rheology of solutions with the morphologies of EFM made up of proteins and polymers. | Ce Shi Shixia Xi Yingchun Han Hao Zhang Jingsheng Liu Yunqi Li | 2019 | Chinese Chemical Letters2019，30，2： | 5 |

| 20 | Preparation of Two-dimensional Ti_2CT_x by Molten Fluorinated Salt Method显示文摘We prepared a two-dimensional transition metal carbide Ti_2CT_x by treatment of Ti_2 AlC in molten fluoride salt. Two fluorinated salt systems were used to etch Al from Ti_2 AlC powder precursor under the argon atmosphere, and then the resulting MXene was delaminated with TBAOH to produce few-layered nanosheets of Ti_2CT_x. The reaction was undergone at different temperatures to study the effect of temperature.The results show that the optimal reaction temperature is 600 ℃ in LiF-NaF-KF system, and 850 ℃ in NaFKF system. The molten salt treated products are delaminated and quasi-2 D MXene sheets can be obtained. The thickness of the MXene sheets prepared from the binary molten salt system is smaller than that of the ternary molten salt system. | 严明 YANG Lei LI Chao ZOU Yunqi | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，2： | 4 |
