| 1 | Multifunctional metasurfaces enabled by simultaneous and independent control of phase and amplitude for orthogonal polarization states显示文摘Monochromatic light can be characterized by its three fun dame ntal properties:amplitude,phase,and polarization.In this work,we propose a versatile,transmission-mode all-dielectric metasurface platform that can independently manipulate the phase and amplitude for two orthogonal states of polarization in the visible frequency range.For proof-o仁concept experimental demonstration,various single-layer metasurfaces composed of subwavelength-spaced titanium-dioxide nanopillars are designed,fabricated,and characterized to exhibit the ability of polarization-switchable multidimensional light-field manipulation,including polarization-switchable grayscale nanoprinting,nonuniform cylindrical lensing,and complex-amplitude holography.We envision the metasurface platform dem on strated here to open new possibilities toward creating compact multifunctional optical devices for applications in polarization optics,information encoding,optical data storage,and security. | Mingze Liu Wenqi Zhu Pengcheng Huo Lei Feng Maowen Song Cheng Zhang Lu Chen Henri JLezec Yanqing Lu Amit Agrawal Ting Xu | 2021 | Light(Science & Applications)2021，10，6： | 8 |

| 3 | Performance enhancement of paper-based SERS chips by shell-isolated nanoparticle-enhanced Raman spectroscopy显示文摘Paper-based flexible surface-enhanced Raman scattering(SERS) chips have been demonstrated to have great potential for future practical applications in point-of-care testing(POCT) due to the potentials of massive fabrication, low cost, efficient sample collection and short signal acquisition time. In this work,common filter paper and Ag@Si O2 core-shell nanoparticles(NP) have been utilized to fabricate SERS chips based on shell-isolated nanoparticle-enhanced Raman spectroscopy(SHINERS). The SERS performance of the chips for POCT applications was systematically investigated. We used crystal violet as the model molecule to study the influence of the size of the Ag core and the thickness of the Si O2 coating layer on the SERS activity and then the morphology optimized Ag@Si O2 core-shell NPs was employed to detect thiram. By utilizing the smartphone as a miniaturized Raman spectral analyzer, high SERS sensitivity of thiram with a detection limit of 10^-9 M was obtained. The study on the stability of the SERS chips shows that a Si O2 shell of 3 nm can effectively protect the as-prepared SERS chips against oxidation in ambient atmosphere without seriously weakening the SERS sensitivity. Our results indicated that the SERS chips by SHINERS had great potential of practical application, such as pesticide residues detection in POCT. | Mingze Sun Binghan Li Xiaojia Liu Jiayin Chen Taotao Mu Lianqing Zhu Jinhong Guo Xing Ma | 2019 | Journal of Materials Science & Technology2019，35，10： | 3 |
| 4 | Zircon U-Pb age, Lu-Hf Isotopic Characteristics and Origin of the Banshanping Granitoid Rocks in East Qinling Orogenic Belt显示文摘The Banshanping granitoid rocks distribute in the east of the North Qinling orogenic belt. It is a diorite-quartz diorite-granodiorite-granite series, spreading in a NW-SE direction, and intrudes into the Erlangping Group. The SiO2 content ranges from 57.04% to 76.56%, Na2O from 2.05% to 4.65%, K2O from 0.84% to 3.40%. Major element characteristics indicate that Banshanping granitoid rocks have properties of I type granotoids. SREE ranges from 36.51 ppm to 473.25 ppm, and LREE/HREE ratios lie between 3.95 and 22.18. Negative Eu anomalies are not obvious in most samples, though there are obvious Nb, P and Ti positive anomalies. The zircon LA-ICP-MS ages of Banshangping granitoid rocks are 496.0±8.1 Ma–486.9±9.3 Ma. Hf isotope shows that 176Hf/177Hf ratios range from 0.282721 to 0.282876, εHf(t) values from 8.5 to 14, all positive, and corresponding modal ages(TDM2) range from 559 Ma to 908 Ma. Based on Hf isotope characteristics and existing SmNd and Rb-Sr isotope data, we consider that the Banshanping granitoid rocks originate from mantlederived material, i.e. the igneous rocks that formed in Neoproterozoic, and there may be a certain amount of crust-derived material during the formation of Banshanping granitoid rocks. | LI Mingze WU Cailai LEI Min QIN Haipeng LIU Chunhua | 2014 | Acta Geologica Sinica(English Edition)2014，88，3： | 2 |
| 5 | Engineering iron-group bimetallic nanotubes as efficient bifunctional oxygen electrocatalysts for flexible Zn–air batteries显示文摘Air cathode performance is essential for rechargeable zinc–air batteries(ZABs).In this study,we develop a self-templated synthesis technique for fabricating bimetallic alloys(FeNi_(3)),bimetallic nitrides(FeNi_(3)N)and heterostructured FeNi_(3)/FeNi_(3)N hollow nanotubes.Owing to its structural and compositional advantages,FeNi_(3)/FeNi_(3)N exhibits remarkable bifunctional oxygen electrocatalytic performance with an extremely small potential gap of 0.68V between the oxygen evolution reaction(OER)and oxygen reduction reaction(ORR).Theoretical calculations reveal reduced Gibbs free energy for the rate-limiting O–O bond formation during OER due to the self-adaptive surface reconfiguration,which induces a synergistic effect between Fe(Ni)OOH developed in situ on the surface and the inner FeNi_(3)/FeNi_(3)N.ZAB fabricated using the FeNi_(3)/FeNi_(3)N catalyst shows high power density,small charge/discharge voltage gap and excellent cycling stability.In addition to its excellent battery performance,the corresponding quasi-solid-state ZAB shows robust flexibility and integrability.The synthesis method is extended to prepare a CoFe/CoFeN oxygen electrocatalyst,demonstrating its applicability to other iron-group elements. | Yanli Niu Shuaiqi Gong Xuan Liu Chen Xu Mingze Xu Shi-Gang Sun Zuofeng Chen | 2022 | eScience2022，2，5： | 2 |
| 6 | Rule based vs Optimization based Workload Control with and without Exogenous Lead Times:An Assessment by Simulation显示文摘Order release is a key production planning and control function,specifically in high variety contexts.A large literature on release methods that balance the workload consequently emerged.These Workload Control methods can be rule based,using a simple greedy heuristic,optimization based or optimization based with lead times that are exogenous.Although all three types of methods have the same objective,their performance has never been compared.Using simulation,this study shows that a better on time delivery performance of jobs can be achieved by the two optimization based release methods.Most importantly,optimization based methods that assume lead times to be exogenous significantly outperform alternative methods in terms of tardiness performance.Rule based and optimization based Workload Control without exogenous lead times overemphasize average lateness reduction,which leads to sequence deviations that offset performance improvements through balancing.In contrast,Workload Control methods that assume lead times to be exogenous limit sequence deviations,which leads to a significant reduction in dispersion of lateness.This has important implication for the future design of order release methods,and managerial practice. | Mingze Yuan Ting Qu Matthias Thürer Lin Ma Lei Liu | 2023 | Journal of Systems Science and Systems Engineering2023，32，5： | 0 |
| 7 | Density-controlled Delaunay triangulation for 2D sea area显示文摘Triangulation is widely used in scientific research,such as finite element mesh generation,surface reconstruction and the reconstruction of the density field data.This paper proposes a new method combining image processing and density-controlled Centroidal Voronoi tessellations to quickly generate a density-controlled constrained Delaunay triangulation for 2D sea area.Firstly,preprocess digital images of the sea area and extract the boundary of seawater region by eight-neighbor searching algorithm.Then,I use 'Odd-Even Testing' method to check if one random vertex is inside the boundary and insert random vertices into the boundary.Finally,we get the CDT of random vertices by density-controlled CVT-Lloyd method.We also give some comparisons with existing methods,and our method performs better in final result of triangulation. | Xu Mingze Liu Zhe Ma Long Liu Yuchen Zhou Yuanfeng | 2016 | Computer Aided Drafting,Design and Manufacturing2016，26，1： | 0 |
| 8 | 2-9 Half-life Measurement of 94mRu44+ at CSRe显示文摘A radioactive nucleus is characterized with an intrinsic half-life. However, for a nuclear species, the half-lives inneutral atoms could be very different from that in highly charged ions. The half-lives of some highly charged ionshave been directly measured at GSI for multiple motivations[1]. In the same case, the nuclear state(i:e the isomer)may be in the range of several tens of microseconds and their half-live can be measured using isochronous massspectrometry. The J = 8+ isomeric state in 94Ru was chosen to test this method. The half-life of this isomer is71 s [2] in neutral atoms, and the excitation energy is 2.64 MeV. The internal conversion coefficient of this decayin neutral atom is 0.335. So its half-life in the bare nucleus would be modified to be 94.78 s when the internalconversion channel is blocked. | Zeng Qi Zhang Yuhu Wang Meng Xu Hushan Tu Xiaolin Zhou Xiaohong Yan Xinliang Chen Ruijiu Huang Wenjia Ge Zhuang Liu Dawei Fu Chaoyi Sun Mingze Mei Bo Xu Xing Xing Yuanming Shuai Peng Zang Yongdong Zhang Wei Xiao Guoqing Yu.A.Litvinov Isao.Tanihata | 2014 | IMP & HIRFL Annual Report2014，，1： | 0 |
| 9 | Tailoring electron vortex beams with customizable intensity patterns by electron diffraction holography显示文摘An electron vortex beam(EVB)carrying orbital angular momentum(OAM)plays a key role in a series of fundamental sci-entific researches,such as chiral energy-loss spectroscopy and magnetic dichroism spectroscopy.So far,almost all the experimentally created EVBs manifest isotropic doughnut intensity patterns.Here,based on the correlation between loc-al divergence angle of electron beam and phase gradient along azimuthal direction,we show that free electrons can be tailored to EVBs with customizable intensity patterns independent of the carried OAM.As proof-of-concept,by using computer generated hologram and designing phase masks to shape the incident free electrons in the transmission elec-tron microscope,three structured EVBs carrying identical OAM are tailored to exhibit completely different intensity pat-terns.Furthermore,through the modal decomposition,we quantitatively investigate their OAM spectral distributions and reveal that structured EVBs present a superposition of a series of different eigenstates induced by the locally varied geo-metries.These results not only generalize the concept of EVB,but also demonstrate an extra highly controllable degree of freedom for electron beam manipulation in addition to OAM. | Pengcheng Huo Ruixuan Yu Mingze Liu Hui Zhang Yan-qing Lu Ting Xu | 2024 | Opto-Electronic Advances2024，7，2： | 0 |

| 11 | Monitoring Forest Growth Disturbance Using Time Series MODIS EVI Data显示文摘Forest growth is mainly currently monitored using in-situ measurements in northeast of China.To effectively monitor forest growth disturbance at large scale,we attempted to use remote sensing technique,particularly,time series MODIS data from 2004 to 2006.The annual time series of 8-day enhanced vegetation index(EVI) dataset was generated and smoothed using a Savitzky-Golay filter.The EVI trajectory during growth season was simulated using a logistic model. From the simulated trajectory,the EVI area of growth season and annual EVI entropy were calculated.These two factors were combined to map the disturbance regions of forest growth. Finally,the disturbance regions were verified using a set of random samples.The result indicates that the disturbance points have distinctively higher entropy and lower peak.Some of these points also show abrupt EVI decline during the midseason of the peak phases or double peaks.This approach is demonstrated to be feasible for disturbance monitoring of forest growth. | Liu Lijuan Pang Yong Zhang Xiaoyang Svein Solberg Fan Wenyi Li Zengyuan Li Mingze | 2012 | Chinese Forestry Science and Technology2012，11，3： | 0 |
| 12 | Janus aramid nanofiber aerogel incorporating plasmonic nanoparticles for high-efficiency interfacial solar steam generation显示文摘Interfacial solar steam generation(ISSG)is a novel and potential solution to global freshwater crisis.Here,based on a facile sol-gel fabrication process,we demonstrate a highly scalable Janus aramid nanofiber aerogel(JANA)as a high-efficiency ISSG device.JANA performs near-perfect broadband optical absorption,rapid photothermal conversion and effective water transportation.Owning to these features,efficient desalination of salty water and purification of municipal sewage are successfully demonstrated using JANA.In addition,benefiting from the mechanical property and chemical stability of constituent aramid nanofibers,JANA not only possesses outstanding flexibility and fire-resistance properties,but its solar steaming efficiency is also free from the influences of elastic deformations and fire treatments.We envision JANA provides a promising platform for mass-production of high-efficiency ISSG devices with supplementary capabilities of convenient transportation and long-term storage,which could further promote the realistic applications of ISSG technology. | Hui Zhang Lei Feng Fengyue Wang Mingze Liu Yingying Zhang Jia Zhu Yanqing Lu Ting Xu | 2023 | Opto-Electronic Advances2023，6，5： | 0 |
| 13 | Energy Absorption by 3D-Printed Mesh Structures with a Negative Poisson’s Ratio显示文摘A negative Poisson's ratio(NPR)structure represents optimal impact-resistance with applications in various fields,including the crash box in vehicles,which absorbs impact kinetic energy.The crash box is designed to deform in response to impact,increasing local structural density,which enhances impact resistance performance.Current studies have only focused on the NPR effect in the plane dimension at low-speed loads.Few studies have considered high-speed impact loads on three-dimensional NPR structures.We have developed two types of AlSi10Mg alloy energy-absorbing structures with NPR using three-dimensional printing technology,and have compared our systems with a conventional hexagonal mesh structure.Sample testing involved split-Hopkinson pressure bar measurements,which showed good agreement with dynamic numerical simulations.When subjected to an impact load,the NPR structure exhibited better impact resistance and energy absorption compared with the positive Poisson's ratio structure.The proposed dual-layer hexagonal structure ensures an NPR effect while exhibiting higher strength and improved stability relative to the conventional concave hexagon structure. | Wenyu Li Weiming Yang Mingze Li Xiang Zhang Ping Zhang Yucheng Zhao Peijian Chen Haishun Liu | 2024 | Acta Metallurgica Sinica(English Letters)2024，37，1： | 0 |
| 14 | Identification of sap flow driving factors of jujube plantation in semi-arid areas in Northwest China显示文摘Jujube is widely cultivated in the semi-arid region of the Loess Plateau in Northwest China due to its high water deficit tolerance.In such an ecologically vulnerable area,it is critical to explore the water consumption processes of key tree species and their responses to driving factors.Sap flow data gathered during a two-year field study in a jujube plantation were analyzed as a surrogate for transpiration measurements.The measured sap flows were related to changes in the soil water content,meteorological factors(the vapor pressure deficit and the level of photosynthetically active radiation),and plant physiological factors(the sap wood area,leaf area and leaf area index).The factors that govern sap flow were found to vary depending on the growing season,and on hourly and daily timescales.The plants’drought tolerance could be predicted based on their peak sap flows and the variation in their sap flow rates at different soil water levels.The sap flow was most strongly affected by the water content of the topmost(0-20 cm)soil layer.Of the studied meteorological factors,the photosynthetically active radiation had a greater effect on sap flow than the vapor pressure deficit.The correlation we found could be applied to predict jujube tree water consumption and assist the design of irrigation scheme. | Wei Xinguang Li Bo Guo Chengjiu Wang Youke He Jianqiang Shouyang Liu Wang Tieliang Yao Mingze | 2017 | International Journal of Agricultural and Biological Engineering2017，10，2： | 0 |
| 15 | 2-8 Direct Mass Measurements of Short-Lived A=2Z+3 Nuclides at CSRe显示文摘Nuclear mass is one of the fundamental quantity of atomic nucleus.The total binding energy of a nucleus derived from the related mass values reflects all the interactions among the constituting nucleons.Masses of short-lived A=2Z+3 nuclei of 112Sn projectile fragments have been measured at the experimental cooler storage ring CSRe,employing the Isochronous mass spectrometry(IMS).The experiment was conducted at the Heavy Ion Research Facility in Lanzhou at the beginning of 2016.The primary beam of 112Sn35+was accumulated in the synchrotron CSRm and accelerated to 467.91 MeV/u.Secondary beam were produced by impinging the high intensity 112Sn35+beam onto a 10 mm beryllium target which was located at the entrance of the radioactive beam line RIBLL2.The projectile fragments of 112Sn emerged from the target were then transmitted,separated in flight through RIBLL2 and finally injected into CSRe. | Liu Junhao Xing Yuanming Yan Xinliang Xu Xing Chen Ruijiu Zeng Qi Zhang Peng Shuai Peng Li Hongfu Zhang Yuhu Wang Meng Yuan Youjin Fu Chaoyi Sun Mingze Chen Xiangchen Bao Tong Lam Yihua | 2016 | IMP & HIRFL Annual Report2016，，1： | 0 |
| 16 | Micro-aluminum powder with bi-or tri-component alloy coating as a promising catalyst:Boosting pyrolysis and combustion of ammonium perchlorate显示文摘A novel design of micro-aluminum(μAl)powder coated with bi-/tri-component alloy layer,such as:Ni-P and Ni-P-Cu(namely,Al@Ni-P,Al@Ni-P-Cu,respectively),as combustion catalysts,were introduced to release its huge energy inside Al-core and promote rapid pyrolysis of ammonium perchlorate(AP)at a lower temperature in aluminized propellants.The microstructure of Al@Ni-P-Cu demonstrates that a three-layer Ni-P-Cu shell,with the thickness of~100 nm,is uniformly supported byμAl carrier(fuel unit),which has an amorphous surface with a thickness of~2.3 nm(catalytic unit).The peak temperature of AP with the addition of Al@Ni-P-Cu(3.5%)could significantly drop to 316.2℃ at high-temperature thermal decomposition,reduced by 124.3℃,in comparison to that of pure AP with 440.5℃.It illustrated that the introduction of Al@Ni-P-Cu could weaken or even eliminate the obstacle of AP pyrolysis due to its reduction of activation energy with 118.28 kJ/mol.The laser ignition results showed that the ignition delay time of Al@Ni-P-Cu/AP mixture with 78 ms in air is shorter than that of Al@Ni-P/AP(118 ms),decreased by 33.90%.Those astonishing breakthroughs were attributed to the synergistic effects of adequate active sites on amorphous surface and oxidation exothermic reactions(7597.7 J/g)of Al@Ni-P-Cu,resulting in accelerated mass and/or heat transfer rate to catalyze AP pyrolysis and combustion.Moreover,it is believed to provide an alternative Al-based combustion catalyst for propellant designer,to promote the development the propellants toward a higher energy. | Chao Wang Ying Liu Mingze Wu Jia Li Ying Feng Xianjin Ning Hong Li Ningfei Wang Baolu Shi | 2024 | Defence Technology(防务技术)2024，33，3： | 0 |
| 17 | Handily etching nickel foams into catalyst-substrate fusion self‐stabilized electrodes toward industrial‐level water electrolysis显示文摘The key challenge of industrial water electrolysis is to design catalytic electrodes that can stabilize high current density with low power consumption(i.e.,overpotential),while industrial harsh conditions make the balance between electrode activity and stability more difficult.Here,we develop an efficient and durable electrode for water oxidation reaction(WOR),which yields a high current density of 1000 mA cm−2 at an overpotential of only 284 mV in 1M KOH at 25°C and shows robust stability even in 6M KOH strong alkali with an elevated temperature up to 80°C.This electrode is fabricated from a cheap nickel foam(NF)substrate through a simple one-step solution etching method,resulting in the growth of ultrafine phosphorus doped nickel-iron(oxy)hydroxide[P-(Ni,Fe)O_(x)H_(y)]nanoparticles embedded into abundant micropores on the surface,featured as a self-stabilized catalyst–substrate fusion electrode.Such self-stabilizing effect fastens highly active P-(Ni,Fe)O_(x)H_(y)species on conductive NF substrates with significant contribution to catalyst fixation and charge transfer,realizing a win–win tactics for WOR activity and durability at high current densities in harsh environments.This work affords a cost-effective WOR electrode that can well work at large current densities,suggestive of the rational design of catalyst electrodes toward industrial-scale water electrolysis. | Zexuan Zhu Xiaotian Yang Jiao Liu Mingze Zhu Xiaoyong Xu | 2023 | Carbon Energy2023，5，10： | 0 |
| 18 | One-pot synthesis of CoO-ZnO/rGO supported on Ni foam for high-performance hybrid supercapacitor with greatly enhanced cycling stability显示文摘The high specific capacitance along with good cycling stability are crucial for practical applications of supercapacitors,which always demands high-performance and stable electrode materials.In this work,we report a series of ternary composites of CoO-ZnO with different fractions of reduced graphene oxide(rGO)synthesized by in-situ growth on nickel foam,named as CZG-1,2 and 3,respectively.This sort of binder-free electrodes presents excellent electrochemical properties as well as large capacitance due to their low electrical resistance and high oxygen vacancies.Particularly,the sample of CZG-2(CoO-ZnO/rGO 20 mg)in a nanoreticular structure shows the best electrochemical performance with a maximum specific capacitance of 1951.8 F/g(216.9 mAh/g)at a current intensity of 1 A/g.The CZG-2-based hybrid supercapacitor delivers a high energy density up to 45.9 Wh/kg at a high power density of 800 W/kg,and kept the capacitance retention of 90.1%over 5000 charge-discharge cycles. | Mingsheng Xu Mingze Sun Sajidur Rehman Kangkang Ge Xiaolong Hu Haizhen Ding Jichang Liu Hong Bi | 2021 | Chinese Chemical Letters2021，32，6： | 0 |
