| 3 | Engineering Two-Phase Bifunctional Oxygen Electrocatalysts with Tunable and Synergetic Components for Flexible Zn-Air Batteries显示文摘Metal-air batteries,like Zn-air batteries(ZABs)are usually suffered from low energy conversion efficiency and poor cyclability caused by the sluggish OER and ORR at the air cathode.Herein,a novel bimetallic Co/CoFe nanomaterial supported on nanoflower-like N-doped graphitic carbon(NC)was prepared through a strategy of coordination construction-cation exchange-pyrolysis and used as a highly efficient bifunctional oxygen electrocatalyst.Experimental characterizations and density functional theory calculations reveal the formation of Co/CoFe heterostructure and synergistic effect between metal layer and NC support,leading to improved electric conductivity,accelerated reaction kinetics,and optimized adsorption energy for intermediates of ORR and OER.The Co/CoFe@NC exhibits high bifunctional activities with a remarkably small potential gap of 0.70 V between the half-wave potential(E_(1/2))of ORR and the potential at 10 mA cm^(-2)(E_(j=10))of OER.The aqueous ZAB constructed using this air electrode exhibits a slight voltage loss of only 60 mV after 550-cycle test(360 h,15 days).A sodium polyacrylate(PANa)-based hydrogel electrolyte was synthesized with strong water-retention capability and high ionic conductivity.The quasi-solid-state ZAB by integrating the Co/CoFe@NC air electrode and PANa hydrogel electrolyte demonstrates excellent mechanical stability and cyclability under different bending states. | Yanli Niu Xue Teng Shuaiqi Gong Mingze Xu Shi-Gang Sun Zuofeng Chen | 2021 | Nano-Micro Letters2021，13，8： | 2 |
| 4 | 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 |
| 5 | High-capacity Bi_(2)O_(3) anode for 2.4 V neutral aqueous sodium-ion battery-supercapacitor hybrid device through phase conversion mechanism显示文摘Aqueous battery-supercapacitor hybrid devices(BSHs)are of great importance to enrich electrochemical energy storage systems with both high energy and power densities.However,further improvement of BSHs in aqueous electrolytes is greatly hampered by operating voltage and capacity limits.Different from the conventional intercalation/de-intercalation mechanism,Bi_(2)O_(3) implements charge storage by a reversible phase conversion mechanism.Herein,taking Bi_(2)O_(3) electrode with wide potential window(from-1.2 to 1 V vs.saturated calomel electrode)and high capacity as battery-type anode,we propose that the overall performance of aqueous BSHs can be greatly upgraded under neutral condition.By paring with stable layer-structuredδ-MnO_(2) cathode,a sodium-ion Bi_(2)O_(3)//MnO_(2) BSH with an ultrahigh voltage of 2.4 V in neutral sodium sulfate electrolyte is developed for the first time.This hybrid device exhibits high capacity(~215 C g^(-1) at 1 mA cm^(-2)),relatively long lifespan(~77.2%capacity retention after 1500 cycles),remarkable energy density(71.7 Wh kg^(-1)@400.5 W kg^(-1))and power density(3204.3 W kg^(-1)@18.8 Wh kg^(-1)).Electrochemical measurements combining a set of spectroscopic techniques reveal the reversible phase conversion between bismuth oxide and metallic bismuth(Bi_(2)O_(3)?Bi0)through Bi^(2+) transition phase in neutral sodium sulfate solution,which can deliver multielectron transfer up to 6,leading to the high-energy BSHs.Our work sheds light on the feasibility of using Bi_(2)O_(3) electrode under neutral condition to address the issue of narrow voltage and low capacity for aqueous BSHs. | Mingze Xu Yanli Niu Xue Teng Shuaiqi Gong Lvlv Ji Zuofeng Chen | 2022 | Journal of Energy Chemistry2022，31，2： | 1 |
| 6 | 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 |
| 7 | 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 |
| 8 | 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 |
| 9 | Non-uniqueness of critical solid fraction considering boundary conditions and strain-rate effects显示文摘The critical solid fraction(ϕJ),which marks the transition between the solid and liquid phases in the jamming diagram,is influenced by several factors.In this study,the dependency ofϕJ on strain rate and boundary conditions is examined through discrete element method simulations considering a frictionless polydisperse granular system.Different approaches are used to determineϕJ.The observed boundary effect is due to the nonuniform solid fraction distribution induced by the clustering of particles close to rigid-wall boundaries at high compression rates.The solid fraction distribution within the sample in the rigid-wall simulations approaches that in the periodic-boundary simulations as the compression rate decreases.With increasing compression rate,the major force transmission network contains fewer mechanically stable particles and a less stable force transmission network.This causes jamming of the granular assembly at a lower solid fraction.These force transmission networks,however,are fragile and disintegrate quickly upon relaxation. | Mingze Xu Zixin Zhang Xin Huang Kevin J.Hanley | 2021 | Particuology2021，19，1： | 0 |

| 11 | 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 |
| 12 | 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 |
| 13 | 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 |
