| 2 | Novel MOF shell-derived surface modification of Li-rich layered oxide cathode for enhanced lithium storage显示文摘Li-rich layered oxide materials have attracted increasing attention because of their high specific capacity(>250 mAh g^(-1)). However, these materials typically suffer from poor cycling stability and low rate performance. Herein, we propose a facile and novel metal-organic-framework(MOF) shell-derived surface modification strategy to construct NiCo nanodots decorated(~5 nm in diameter) carbon-confined Li_(1.2)Mn_(0.54) Ni_(0.13)Co_(0.13)O_2 nanoparticles(LLO@C&NiCo). The MOF shell is firstly formed on the surface of as-prepared Li_(1.2)Mn_(0.54)Ni_(0.13)Co_(0.13)O_2 nanoparticles via low-pressure vapor superassembly and then is in situ converted to the NiCo nanodots decorated carbon shell after subsequent controlled pyrolysis.The obtained LLO@C&NiCo cathode exhibits enhanced cycling and rate capability with a capacity retention of 95% after 100 cycles at 0.4 C and a high capacity of 159 mAh g^(-1) at 5 C, respectively, compared with those of LLO(75% and 105 mAh g^(-1)). The electrochemical impedance spectroscopy and selected area electron diffraction analyses after cycling demonstrate that the thin C&NiCo shell can endow LLO with high electronic conductivity and structural stability, indicating the undesired formation of the spinel phase initiated from the particle surface is efficiently suppressed. Therefore, this presented strategy may open a new avenue on the design of high-performance electrode materials for energy storage. | Zhitong Xiao Jiashen Meng Qi Li Xuanpeng Wang Meng Huang Ziang Liu Chunhua Han Liqiang Mai | 2018 | Science Bulletin2018，63，1： | 8 |
| 3 | Mathematical model of heat transfer for bloom continuous casting显示文摘A mathematical model for heat transfer during solidification in continuous casting of automobile steel,was established on researching under the influence of the solidifying process of bloom quality of CCM in the EAF steelmaking shop,at Shijiazhuang Iron and Steel Co.Ltd.Several steel grades were chosen to research,such as,40Cr and 42CrMo.According to the results of the high temperature mechanical property tests of blooms,the respective temperature curves for controlling the solidification of different steels were acquired,and a simulating software was developed.The model was verified using two methods,which were bloom pin- shooting and surface strand temperature measuring experiments.The model provided references for research on the solidifying proc- ess and optimization of a secondary cooling system for automobile steel.Moreover,it was already applied to real production.The calculated temperature distribution and solidification trend of blooms had offered a reliable theory for optimizing the solidifying process of blooms,increasing withdrawal speed,and improving bloom quality.Meanwhile,a new secondary cooling system was designed to optimize a secondary cooling water distribution,including choice and arrangements of nozzles,calculation of cooling water quantity,and so on. | Qing Liu Liangzhou Wang Liqiang Zhang Liguo Cao Xiuzhong Ding Mei Liang Yongge Qi | 2008 | Journal of University of Science and Technology Beijing2008，15，1： | 7 |
| 4 | Powertrain design and energy management of a novel coaxial series-parallel plug-in hybrid electric vehicle显示文摘For a series plug-in hybrid electric vehicle,higher working efficiency can be achieved by the drive system with two small motors in parallel than that with one big motor alone.However,the overly complex structure will inevitably lead to a substantial increase in the development cost.To improve the system price-performance ratio,a new kind of series-parallel hybrid system evolved from the series plug-in hybrid system is designed.According to the technical parameters of the selected components,the system model is established,and the vehicle dynamic property and pure electric drive economy are evaluated.Based on the dynamic programming,the energy management strategy for the drive system under the city driving cycle is developed,and the superiority validation of the system is completed.For the studied vehicle driven by the designed series-parallel plug-in hybrid system,compared with the one driven by the described series plug-in hybrid system,the dynamic property is significantly improved because of the multi-power coupling,and the fuel consumption is reduced by 11.4%with 10 city driving cycles.In a word,with the flexible configuration of the designed hybrid system and the optimized control strategy of the energy management,the vehicle performance can be obviously improved. | ZHANG LiPeng QI BingNan ZHANG RunSheng LIU JingChao WANG LiQiang | 2016 | Science China(Technological Sciences)2016，59，4： | 7 |

| 6 | Engineering Mesoporous Structure in Amorphous Carbon Boosts Potassium Storage with High Initial Coulombic Efficiency显示文摘Amorphous carbon shows great potential as an anode material for high-performance potassium-ion batteries;however,its abundant defects or micropores generally capture K ions,thus resulting in high irreversible capacity with low initial Coulombic efficiency(ICE)and limited practical application.Herein,pore engineering via a facile self-etching strategy is applied to achieve mesoporous carbon(meso-C)nanowires with interconnected framework.Abundant and evenly distributed mesopores could provide short K^+ pathways for its rapid diffusion.Compared to microporous carbon with highly disordered structure,the meso-C with Zn-catalyzed short-range ordered structure enables more K^+to reversibly intercalate into the graphitic layers.Consequently,the mesoC shows an increased capacity by ~100 mAh g^-1 at 0.1 A g^-1,and the capacity retention is 70.7% after 1000 cycles at 1 A g^-1.Multiple in/ex situ characterizations reveal the reversible structural changes during the charging/discharging process.Particularly,benefiting from the mesoporous structure with reduced specific surface area by 31.5 times and less defects,the meso-C generates less irreversible capacity with high ICE up to 76.7%,one of the best reported values so far.This work provides a new perspective that mesopores engineering can effectively accelerate K^+ diffusion and enhance K^+ adsorption/intercalation storage. | Ruiting Guo Xiong Liu Bo Wen Fang Liu Jiashen Meng Peijie Wu Jinsong Wu Qi Li Liqiang Mai | 2020 | Nano-Micro Letters2020，12，11： | 5 |
| 7 | Implementation of regional Acute Stroke Care Map increases thrombolysis rates for acute ischaemic stroke in Chinese urban area in only 3 months显示文摘Background The rate of intravenous thrombolysis for acute ischaemic stroke remains low in China.We investigated whether the implementation of a citywide Acute Stroke Care Map(ASCaM)is associated with an improvement of acute stroke care quality in a Chinese urban area.Methods The ASCaM comprises 10 improvement strategies and has been implemented through a network consisting of 20 tertiary hospitals.We identified 7827 patients with ischaemic stroke admitted from April to October 2017,and 506 patients underwent thrombolysis were finally included for analysis.Results Compared with‘pre-ASCaM period’,we observed an increased rate of administration of tissue plasminogen activator within 4.5 hours(65.4% vs 54.5%;adjusted OR,1.724;95% CI 1.21 to 2.45;p=0.003)during‘ASCaM period’.In multivariate analysis models,‘ASCaM period’was associated with a significant reduction in onset-to door time(114.1±55.7 vs 135.7±58.4 min,p=0.0002)and onset-to needle time(ONT)(169.2±58.1 vs 195.6±59.3 min,p<0.0001).Yet no change was found in door-to needle time.Clinical outcomes such as symptomatic intracranial haemorrhage,favourable functional outcome(modified Rankin Scale≤2)and in-hospital mortality remained unchanged.Conclusion The implementation of ASCaM was significantly associated with increased rates of intravenous thrombolysis and shorter ONT.The ASCaM may,in proof-of principle,serve as a model to reduce treatment delay and increase thrombolysis rates in Chinese urban areas and possibly other highly populated Asian regions. | Yi Sui Jianfeng Luo Chunyao Dong Liqiang Zheng Weijin Zhao Yao Zhang Ying Xian Huaguang Zheng Bernard Yan Mark Parsons Li Ren Ying Xiao Haoyue Zhu Lijie Ren Qi Fang Yi Yang Weidong Liu Bing Xu | 2021 | Stroke & Vascular Neurology2021，6，1： | 4 |
| 8 | Seasonal variations and bioavailability of inorganic phosphorus in soils of Yeyahu Wetland in Beijing,China显示文摘Phosphorus(P) in soils has an important influence on the development and productivity of wetland. The objective of this study was to investigate the distribution,bioavailability and seasonal variations of inorganic phosphorus(IP) in soils of Yeyahu Wetland.The results showed that the concentration of Ca-bound P(Ca-P) remained the main occurrence in all IP fractions despite the season,at the same time the Al-bound P(Al-P) was always the lowest IP fraction despite the season.Al-P and Fe-bound P (Fe-P) concentration were all reached the highest value in May and the lowest in November,which was opposite to the occluded P(Oc-P) fraction.The notable higher Oc-P concentration in November observed in this study was probably due to the decomposition of plants and the subsequently releasing of oxides to soils.Ca-P didn't change much with season variations.Exchangeable P(Ex-P) and Oc-P were all positively correlated with soil moisture content and organic matter content,but Al-P was negatively correlated with these two soil properties.As a stable form,Ca-P was not associated with soil properties.Al-P,Fe-P and Ca-P might contribute to the storage of P in studied wetland with the principle component analysis results.The concentration rank order of the bio-available P in soils was generally as follows:Olsen-P > Algal available P(AAP) > Water soluble P(WSP) > Readily desorbed P(RDP).Olsen-P was positively correlated with Ex-P and Oc-P,and it was thought to be a more suitable indicator for bio-available P in soils. | ZHANG Jing LI Min LIU Shuang LIU Yujin ZHANG Liqiang CAO Qi SUN Dezhi | 2011 | International Journal of Sediment Research2011，26，2： | 4 |
| 9 | Information acquisition system of multipoint soil surface height variation for profiling mechanism of seeding unit of precision corn planter显示文摘The emergence rate and vitality of maize are directly affected by the sowing depth,and the uniformity of this depth is an important performance indicator of a planter,while the effective soil surface height information acquisition is the prerequisite for ensuring the accuracy of sowing depth control.The soil surface height variation acquisition system of a precision corn planter often produces profiling errors when performing active profiling due to interference from ground debris.In this study,a multipoint soil surface height variation information acquisition system was investigated,which consists of a ranging sensor group and a microcontroller unit(MCU)using a data comparison and screening method.The structure and specifications of the ranging sensors were determined according to the soil surface height variation and debris size,and a nonessential profiling control program was developed.Performed tests on the information acquisition system indicated that the measurement accuracy of the system was 3 mm,and when advancing at a speed of 8 km/h,the accuracy of the profiling decision and the system stability were 97.1%and 94.1%,respectively,indicating that the system was capable of nonessential profile control.The designed ranging system could provide a reference for the design of a ground information acquisition system of precision planters with an active profiling mechanism. | Bo Zhang Wei Zhang Liqiang Qi Haiba Fu Lijuan Yu Rui Li Yue Zhao Xinxian Ma | 2018 | International Journal of Agricultural and Biological Engineering2018，11，6： | 4 |
| 10 | High‐sensitivity distributed dynamic strain sensing by combining Rayleigh and Brillouin scattering显示文摘The phase-sensitive optical time-domain reflectometry(φ-OTDR)is a good candidate for distributed dynamic strain sensing,due to its high sensitivity and fast measurement,which has already been widely used in intrusion monitoring,geophysical exploration,etc.For the frequency scanning basedφ-OTDR,the phase change manifests itself as a shift of the intensity distribution.The correlation between the reference and measured spectra is employed for relative strain demodulation,which has imposed the continuous measurement for the absolute strain demodulation.Fortunately,the Brillouin optical time domain analysis(BOTDA)allows for the absolute strain demodulation with only one measurement.In this work,the combination of theφ-OTDR and BOTDA has been proposed and demonstrated by using the same set of frequency-scanning optical pulses,and the frequency-agile technique is also introduced for fast measurements.A 9.9 Hz vibration with a strain range of 500 nεhas been measured under two different absolute strains(296.7μεand 554.8με)by integrating the Rayleigh and Brillouin information.The sub-micro strain vibration is demonstrated by theφ-OTDR signal with a high sensitivity of 6.8 nε,while the absolute strain is measured by the BOTDA signal with an accuracy of 5.4με.The proposed sensor allows for dynamic absolute strain measurements with a high sensitivity,thus opening a door for new possibilities which are yet to be explored. | Benzhang Wang Dexin Ba Qi Chu Liqiang Qiu Dengwang Zhou Yongkang Dong | 2020 | Opto-Electronic Advances2020，3，12： | 3 |
| 11 | An Improved Grid Security Infrastructure by Trusted Computing显示文摘Current delegation mechanism of grid security infrastructure (GSI) can’t satisfy the requirement of dynamic, distributed and practical security in grid virtual organization. To improve this situation, a TC-enabled GSI is discussed in this paper. With TC-enabled GSI, a practical delegation solution is proposed in this paper through enforcing fine granularity policy over distributed platforms with the emerging trusted computing technologies. Here trusted platform module is treated as a tamper-resistance module to improve grid security infrastructure. With the implement of Project Daonity, it is demonstrated that the solution could gain dynamic and distributed security in grid environment. | YAN Fei ZHANG Huanguo SUN Qi SHEN Zhidong ZHANG Liqiang QIANG Weizhong | 2006 | Wuhan University Journal of Natural Sciences2006，11，6： | 3 |
| 12 | Fermi surface gapping in the hidden order state of PrFe_(4)P_(12);by point-contact spectroscopy显示文摘We have applied point-contact spectroscopy(PCS) to investigate the nonmagnetic hidden order(HO) state of the skutterudite compound PrFe_(4)P_(12) with its transition temperature THO~6.5 K. Its point-contact conductance curves exhibit a reproducible gap structure in the HO state below THOand its temperature dependent gap magnitude follows a BCS-like mean-field behavior.A Fano-like conductance shape is observed to emerge below the coherence temperature of PrFe_(4)P_(12). In a magnetic field, the gap feature is gradually suppressed and evolves into a pronounced Fano peak, signaling the heavy fermion state and vividly demonstrating the competition between HO and the formation of heavy fermion states. Our results strongly suggest the itinerant characteristic of f electrons in PrFe_(4)P_(12), which constrains theoretical models to explain the HO mechanism. | Tian Le LiQiang Che Qi Huang Kevin Huang ZhaoFeng Ding Lei Shu Xin Lu | 2022 | Science China(Physics,Mechanics & Astronomy)2022，65，3： | 1 |

| 15 | Niobium oxyphosphate nanosheet assembled two-dimensional anode material for enhanced lithium storage显示文摘The development of high-capacity and high-rate anodes has become an attractive endeavor for achieving high energy and power densities in lithium-ion batteries(LIBs).Herein,a new-type anode material of reduced graphene oxide(rGO) supported niobium oxyphosphate(NbOPO_4) nanosheet assembled twodimensional composite material(NbOPO_4/rGO) is firstly fabricated and presented as a promising highperformance LIB anode material.In-depth electrochemical analyses and in/ex situ characterizations reveal that the intercalation-conversion reaction takes place during the first discharge process,followed by the reversible redox process between amorphous NbPO_4 and Nb which contributes to the reversible capacity in the subsequent cycles.Meanwhile,the lithiation-generated Li3 PO_4,behaving as a good lithium ion conductor,facilitates ion transport.The rGO support further regulates the structural and electron/ion transfer properties of NbOPO_4/rGO composite compared to neat NbOPO_4, resulting in greatly enhanced electrochemical performances.As a result,NbOPO_4/rGO as a new-type LIB anode material achieves a high capacity of 502.5 mAh g^(-1) after 800 cycles and outstanding rate capability of 308.4 mAh g^(-1) at 8 A g^(-1).This work paves the way for the deep understanding and exploration of phosphate-ba sed high-efficiency anode materials for LIBs. | Bo Wen Ruiting Guo Xiong Liu Wen Luo Qiu He Chaojiang Niu Jiashen Meng Qi Li Yan Zhao Liqiang Mai | 2021 | Journal of Energy Chemistry2021，30，2： | 1 |

| 18 | Distribution regularity of downwash airflow under rotors of agricultural UAV for plant protection显示文摘In the plant protection spray operation of UAVs,the process of droplet from formation to sedimentation target is affected by airflow,easy to form uneven deposition.Accurately description of rotor downwash flow field,clarification of velocity vector distribution at different heights of the UAV rotor flow field,simulation of the flow field with high precision,which are the prerequisites for accurately analyzing the droplet deposition distribution in rotor downwash flow field.Based on CFD method,the detail of rotor flow field was numerically calculated.Taking LTH-100 single-rotor agricultural UAV as the research object,the three-dimensional solid model of UAV was established,the Reynolds average N-S equation was used as the control equation and the RNGκ-εas the turbulence model to simulate the flow field of UAV in hover and lateral wind conditions,the wind velocity distribution at different altitudes of rotor downwash flow field was studied.The simulation results of the hover state showed that:In the flow field,the peak velocity appears in a circular distribution below the distal axis of the rotor.With the decrease of height,the peak velocity distribution area showed a tendency to expand gradually after small shrinkage;When the distance from the rotor was not more than 1.5 m,the downwash flow field presented an axisymmetric distribution based on the rotor axis,and the variation rate of velocity in the peak velocity was basically the same,turbulence in downwash flow field made the flow field more complex when the distance from rotor was larger than 2.0 m.On this basis,the optimal flight altitude of UAV is 1.5 m.Wind velocity test of the flow field was carried out on a rotor test bench,wind velocities at four altitudes of 0.5 m,1.0 m,1.5 m and 2.0 m were measured to verify the coincidence between the simulated and measured values.The test results showed that:the relative error between the measured and simulated values at four measurement heights were between 0.382-0.524,and the overall average relative errors was 0.430,which verified the confidence level of simulated values for measured values.When the lateral wind velocity was 3 m/s,4 m/s and 5 m/s,the simulation results showed that:The distribution trend of airflow velocity at the same altitude in lateral-wind flow field with different wind speeds was similar;When the lateral wind speed was 5 m/s,the coupling field formed by the lateral wind and rotor airflow cannot reach the height of 2 m below the rotor.The results of this study can provide more accurate environmental conditions for theoretical analysis of droplet deposition regularity in the flow field,and also provide methodological guidance for the related research on rotor flow field of multi-rotor UAV. | Xin Liu Wei Zhang Haiba Fu Xiaoming Fu Liqiang Qi | 2021 | International Journal of Agricultural and Biological Engineering2021，14，3： | 1 |
| 19 | Risk assessment and identification of factors influencing the historical concentrations of microcystin in Lake Taihu, China显示文摘Understanding the history of microcystins(MCs)pollution in large lakes can help inform future lake management.We collected sediment cores from Lake Taihu to:investigate the long-term record of MCs(MC-LR,MC-YR,and MC-RR),explore the main environmental drivers of MCs,and assess their public health and ecological risks.Results showed that MCs content in all cores increased over time.The core from north Taihu had the highest MC concentrations,with an average total MCs(sum of MC-LR,MC-YR,and MC-RR=TMCs)content of(74.31±328.55)ng/g.The core from eastern Taihu showed the lowest average TMCs content of(2.91±3.95)ng/g.PCA showed that sediment MCs at the three sites were positively correlated with sediment chlorophyll-a.MC-LR and MC-YR in northern and western Taihu negatively correlated with both the sediment total organic carbon/sediment total nitrogen ratio(STOC/STN)andwater nitrate(NO_(3)^(−)-N)concentration,but three MC congeners at eastern Taihu showed positive correlations with water orthophosphate(PO_(4)^(3−)-P),NO_(3)^(−)-N,and STOC/STN.Generalized additive model analysis at each site revealed that NO_(3)^(−)-N was the main TMCs driver in northern andwestern Taihuwhere phytoplankton dominated,whereasPO_(4)^(3−)-P was the main TMCs driver in eastern Taihu where macrophytes dominated.At the whole lake scale,total phosphorus(TP)andPO_(4)^(3−)-P were the most important environmental drivers influencing MCs;TP explained 47.4%,44.2%,and 47.6%while orthophosphate explained 34.8%,31.2%,and 34.7%of the deviance on TMCs,MC-LR,and MC-YR,respectively.NO_(3)^(−)-N also showed a strong effect on MCs variation,especially on MC-YR.Risk assess-ment showed that both ecological and public health risk has increased in recent years.We conclude that while control of phosphorus and nitrogen input should be a major focus for future lake management,lake zone-specificmanagement strategiesmay also be important. | Chen Cheng Alan D.Steinman Kaiye Zhang Qi Lin Qingju Xue Xing Wang Liqiang Xie | 2023 | Journal of Environmental Sciences2023，，5： | 0 |
| 20 | Clinical characteristics and treatment outcomes of Chinese diffuse large B-cell lymphoma patients in the era of rituximab(2005–2018)显示文摘Background Rituximab combined with cyclophosphamide,doxorubicin hydrochloride,vincristine,and prednisone(R-CHOP)regimen has improved the survival of diffuse large B-cell lymphoma(DLBCL)patients worldwide,compared with CHOP alone.Several limitations were seen in previous studies of Chinese DLBCL patients treated with R-CHOP or R-CHOP-like regimens.This study aimed to investigate the clinical characteristics and treatment outcomes of Chinese DLBCL patients treated with the standard first-line treatment.Methods Clinical data were collected from DLBCL patients who received frontline R-CHOP or R-CHOP-like regimens at the Cancer Hospital Chinese Academy of Medical Sciences&Peking Union Medical College(CHCAMS)between January 1,2005,and December 31,2018.The treatment outcomes were compared with those of patients diagnosed with DLBCL between 2004 and 2017 and who received immunochemotherapy from the United States Surveillance,Epidemiology,and End Results(SEER)database.Survival rates were estimated using the Kaplan-Meier method and compared using the log-rank test.Multivariate analysis of progression-free survival(PFS)and overall survival(OS)was performed using Cox proportional hazard regression.Results Overall,1084 patients from the CHCAMS and 4013 patients from the SEER database were included in the study.As of April 30,2022,the median follow-up period for the CHCAMS group was 87.3(range:0.5-195.4)months.For the CHCAMS group,the 5-year PFS and OS rates were 61.7%(95%confidence interval[CI]:58.8-64.7%)and 70.6%(95%CI:67.8-73.4%),respectively.For the SEER group,the 5-year OS rate was 66.5%(95%CI:65.0-68.0%),which was inferior to that of the CHCAMS group(P<0.001).After adjusting for clinical factors and treatment,no significant difference was observed in the OS between the CHCAMS and SEER groups(P=0.867).In the CHCAMS group,multivariate analysis showed that an Eastern Cooperative Oncology Group performance status score≥2,presence of B symptoms,Ann Arbor stage III-IV,elevated serumβ2-microglobulin levels,and bulky mass were independent adverse prognostic factors affecting PFS and OS(P<0.05).Additionally,patients aged over 60 years,elevated lactate dehydrogenase levels,and more than two extranodal sites were independent adverse prognostic factors for OS(P<0.05).Local radiotherapy was significantly associated with better PFS(P<0.001)and OS(P=0.001).Conclusion After adjusting for clinical and treatment-related factors,no significant difference was observed in the 5-year OS rate between Chinese DLBCL patients treated with standard first-line treatment and those from the SEER database. | Yuankai Shi Haizhu Chen Yan Qin Jianliang Yang Peng Liu Xiaohui He Shengyu Zhou Liqiang Zhou Changgong Zhang Yongwen Song Yueping Liu Lin Gui Shulian Wang Jing Jin Hui Fang Shunan Qi Ning Li Yu Tang Xin Wang Sheng Yang | 2023 | Cancer Pathogenesis and Therapy2023，1，1： | 0 |
