| 1 | Fabrication of low-resistance LaNi_xO_(3+δ) thin films for ferroelectric device electrodes显示文摘LaNiO_3 thin films with different La/Ni ratios were deposited on Si substrates by sol-gel process. The electrical resistivities of LaNi_xO_(3+δ) films with different La/Ni ratios were measured by four-probe method.LaNi_(0.95)O_(3+δ) thin film has the lowest resistivity. First-principle calculations show that LaNi_(0.95)O_(3+δ) has the largest Ni-O-Ni bond angle and the shortest Ni-O bond length, which means LaNi_(0.95)O_(3+δ) has the strongest metallic property, hence, the electrical resistivity is the lowest. Au/PZT(PbZr_(0.52)Ti_(0.48)O_3)/LaNi_xO_(3+δ) and Au/PZT/Pt ferroelectric capacitors were fabricated to evaluate LaNi_xO_(3+δ) as a bottom electrode. It is shown that fatigue properties of PZT films can be significantly improved by using LaNi_xO_(3+δ) instead of Pt as the bottom electrode. The Ⅰ-Ⅴ test results of PZT films show that LaNi_(0.95)O_(3+δ) as bottom electrode can reduce the threshold voltages of PZT films, suggesting that La/Ni ratio in LaNi_xO_(3+δ)has a large influence on the film properties. | Mi Xiao Zebin Zhang Weikang Zhang Ping Zhang Kuibo Lan | 2018 | Journal of Rare Earths2018，36，8： | 2 |
| 2 | Dealloying-constructed hierarchical nanoporous bismuth-antimony anode for potassium ion batteries显示文摘Bi-Sb alloys are appealing anode materials for potassium ion batteries(PIBs)but challenged by their enormous volumetric variation during operation.Herein,a facile one-step dealloying protocol was devised and utilized to prepare the Bi-Sb alloys that manifest an exotic bicontinuous hierarchical nanoporous(np)microstructure ideal for volume-change mitigation and K+transport percolation.The growth mechanism fostering the peculiar morphology of the np-(Bi,Sb)alloys was investigated and clarified via operando X-ray(XRD)and ex-situ scanning electron microscopy(SEM).In particular,the np-Bi6Sb2 electrode,optimized for comprehensive electrochemical performance,achieves decent reversible capacities and a superior lifespan,as benchmarked with the monometallic references and other Bi-Sb alloy electrodes.The(de)potassiation mechanism of the np-(Bi,Sb)alloys was studied by operando XRD and further rationalized by density functional theory(DFT)calculations,whereby a homogeneous(segregation-free)and robust two-step electrochemically-driven phase transformations’catenation of(Bi,Sb)↔K(Bi,Sb)2↔K3(Bi,Sb)was reliably established to substantiate the outstanding reversibility of the np-(Bi,Sb)anodes in PIBs. | Hui Gao Kuibo Yin Zhiyuan Guo Ying Zhang Wensheng Ma Wanfeng Yang Ke Sun Zhangquan Peng Zhonghua Zhang | 2021 | Fundamental Research2021，1，4： | 2 |
| 3 | integrated structure for recognition of different joint motion states with the assistance of a deep learning algorithm显示文摘Accurate motion feature extraction and recognition provide critical information for many scientific problems.Herein,a new paradigm for a wearable seamless multimode sensor with the ability to decouple pressure and strain stimuli and recognize the different joint motion states is reported.This wearable sensor is integrated into a unique seamless structure consisting of two main parts(a resistive component and a capacitive component)to decouple the different stimuli by an independent resistance-capacitance sensing mechanism.The sensor exhibits both high strain sensitivity(GF=7.62,0-140%strain)under the resistance mechanism and high linear pressure sensitivity(S=3.4 kPa^(-1),0-14 kPa)under the capacitive mechanism.The sensor can differentiate the motion characteristics of the positions and states of different joints with precise recognition(97.13%)with the assistance of machine learning algorithms.The unique integrated seamless structure is achieved by developing a layer-bylayer casting process that is suitable for large-scale manufacturing.The proposed wearable seamless multimode sensor and the convenient process are expected to contribute significantly to developing essential components in various emerging research fields,including soft robotics,electronic skin,health care,and innovative sports systems applications. | Lei Wen Meng Nie Pengfan Chen Yu-na Zhao Jingcheng Shen Chongqing Wang Yuwei Xiong Kuibo Yin Litao Sun | 2022 | Microsystems & Nanoengineering2022，8，1： | 1 |
| 4 | Thermodynamic and Kinetic Analysis of Low-temperature Thermal Reduction of Graphene Oxide显示文摘The thermodynamic state and kinetic process of low-temperature deoxygenation reaction of graphene oxide(GO) have been investigated for better understanding on the reduction mechanism by using Differential Scanning Calorimetry(DSC), Thermogravimetry-Mass Spectrometry(TG-MS), and X-ray Photoelectron Spectroscopy(XPS). It is found that the thermal reduction reaction of GO is exothermic with degassing of CO_2, CO and H_2O. Graphene is thermodynamically more stable than GO. The deoxygenation reaction of GO is kinetically controlled and the activation energy for GO is calculated to be 167 k J/mol(1.73 e V/atom). | Kuibo Yin Haitao Li Yidong Xia Hengchang Bi Jun Sun Zhiguo Liu Litao Sun | 2011 | Nano-Micro Letters2011，3，1： | 1 |
| 5 | Efficient rejuvenation of heterogeneous{[(Fe_(0.5)Co_(0.5))_(0.75)B_(0.2)Si_(0.05)]_(96)Nb_(4)}_(99.9)Cu_(0.1) bulk metallic glass upon cryogenic cycling treatment显示文摘The effects of cryogenic thermal cycling on deformation behaviour and structural variation of{[(Fe_(0.5)Co_(0.5))_(0.75)B_(0.2)Si_(0.05)]_(96)Nb_(4)}_(99.9)Cu_(0.1) bulk metallic glass(BMG)were studied and compared with Cufree[(Fe_(0.5)Co_(0.5))_(0.75)B_(0.2)Si_(0.05)]_(96)Nb_(4) BMG.After thermal-cycled treatment between 393 K and cryogenic temperature,the{[(Fe_(0.5)Co_(0.5))_(0.75)B_(0.2)Si_(0.05)]_(96)Nb_(4)}_(99.9)Cu_(0.1)BMG obtained a plastic strain of 7.4%combined with a high yield strength of 4350 MPa.The excellent soft magnetic properties were maintained after CTC treatment.The minor addition of Cu element results in an initial nano-sized heterogeneity in the matrix,which facilitates the rejuvenation process during thermal cycling,and brings to a low optimal thermal temperature of 393 K,making the{[(Fe_(0.5)Co_(0.5))_(0.75)B_(0.2)Si_(0.05)]_(96)Nb_(4)}_(99.9)Cu_(0.1) BMG more attractive in industrial application.During thermal cycling,the formation of more soft regions leads to the increase of structural heterogeneities,which is beneficial to the initiation of shear transition zones and the formation of multiple shear bands,and thus results in the enhancement of plasticity.This study links the subtle variation of specific structure with macroscopic mechanical properties,and provides a new insight of composition selection for cryogenic thermal cycling treatment. | Siyi Di Qianqian Wang Yiyuan Yang Tao Liang Jing Zhou Lin Su Kuibo Yin Qiaoshi Zeng Litao Sun Baolong Shen | 2022 | Journal of Materials Science & Technology2022，，2： | 1 |

| 8 | Eutectic-derived high-entropy nanoporous nanowires for efficient and stable water-to-hydrogen conversion显示文摘Combining multiple metal elements into one nanostructure merits untold application potential but is still a challenge for the traditional bottom-up synthesis method.Herein,we propose a eutectic-directed self-templating strategy to prepare two multicomponent nanostructured alloys(PtPdRhIrNi(D-SN)and NiPtPdRhIrAl(D-SS))through the combination of rapid solidification with dealloying.The PtPdRhIrNi nanoporous nanowires(NPNWs)represent a new family of high-entropy alloys(HEAs)containing delicate hierarchical nanostructure with ultrafine ligament sizes of~2 nm in addition to one-dimensional(1D)morphology.Moreover,the PtPdRhIrNi NPNWs display excellent electrocatalytic activity and stability toward hydrogen evolution reaction,with the low overpotential of 22 and 55 mV to afford a current density of 10 mA·cm^(−2)in 0.5 M H_(2)SO_(4)and 1.0 M KOH electrolytes,respectively.The enhanced electrocatalytic performance can be attributed to the high-entropy effect favoring the surface electronic structure for the optimized activity,the promotion impact of Ni,1D morphology facilitating the electron transport,and the nanoporous structure promoting the electrolyte diffusion. | Ying Wang Bin Yu Ming He Zhihua Zhai Kuibo Yin Fangong Kong Zhonghua Zhang | 2022 | Nano Research2022，15，6： | 1 |

| 11 | A plastic FeNi-based bulk metallic glass and its deformation behavior显示文摘The strength and plasticity of Fe_(39)Ni_(39)B_(12.82)Si_(2.75)Nb_(2.3)P_(4.13)bulk metallic glass(BMG)are improved simultaneously by modulating atomic-scale structure through fluxing treatment.The compression strength increases from 3074 to 4220 MPa,and the plastic strain is enlarged from 10.7%to more than 50%.The increased mechanical properties of the fluxed Fe Ni BSi Nb P BMG originate from the optimization of atomic-scale structure.More icosahedral-like clusters(ILCs)and crystal-like clusters(CLCs)are found in this Fe Ni-based BMG with fluxing treatment,and the ILCs are usually surrounded by CLCs.Furthermore,phase separation and a sandwich-like heterogeneous structure of SB are also observed during deformation,indicating the multiscale deformation mechanism and a stable shear-band evolution.The unique'ILC surrounded by CLCs'structure and phase separation lead to a stable plastic deformation process with strong interactions of multiple shear bands,thereby the improved plasticity and strength.This work provides useful guidelines to develop strong and plastic Fe-based BMGs from a structural aspect. | Jing Zhou Qianqian Wang Qiaoshi Zeng Kuibo Yin ing Wang Junhua Luan Litao Sun Baolong Shen | 2021 | Journal of Materials Science & Technology2021，，17： | 1 |
| 12 | Aligning Fe_(2)O_(3)photo-sheets on TiO_(2)nanofibers with hydrophilic and aerophobic surface for boosting photoelectrochemical performance显示文摘Photoelectrochemical(PEC)nanomaterials are critical to producing clean oxygenation or value-added chemical production by utilizing sustainable solar energy,but are always limited by simultaneous integration of architectural engineering and electronic regulation in one structure.Directed by density functional theory(DFT)calculations and finite element analysis(FEA),the bioinspired ivy-like Fe_(2)O_(3)heterostructures with enriched oxygen defects on TiO_(2)nanofibers are designed for boosting PEC performances.Ivy-like Fe_(2)O_(3)photo-sheets remarkably enhanced the light harvesting by multiple light-mater interactions.The oxygen vacancies on Fe_(2)O_(3)photo-sheets could aid the photons catching and promote the reactivity at active sites.More importantly,demonstrated by a well-designed dynamic observation,the abundant tip-edges within ivy-like Fe_(2)O_(3)photo-sheets enabled the surface of heterostructure with hydrophilic and aerophobic properties.The functionalized surface allowed the rapid desorption of produced bubbles and thus ensured a high density of unoccupied active sites for electrolyte accessing.Featured by these attributes,the Fe_(2)O_(3)@TiO_(2)nanofibers delivered an excellent photocurrent of 40.8 mA/mg,high donor density(1.2×10^(18)cm^(−3)),and rapid oxygen production rate(1 mmol/(L∙h)).This work demonstrates a new strategy on nano-structural design for enhancing light-harvesting and making a hydrophilic/aerophobic surface on low-dimensional oxide nanomaterial,holding great potential on designing high-performance PEC devices for producing survival source gas,carbon-neutral fuel,and valuedchemicals. | Xiangyu Meng Qi Zhan Yanan Wu Mengmeng Zhu Ken Liu Na Wang Kuibo Yin Yueming Sun Shuai Dong Yunqian Dai | 2023 | Nano Research2023，16，3： | 0 |
| 13 | Effect of the addition of Al-Ti-C master alloy on the microstructure and microhardness of a cast Al-10Mg alloy显示文摘The microstructure and microhardness of a cast Al-10wt%Mg (henceforth Al-10Mg) alloy with 0.2wt% addition of Al-5Ti-0.25C master alloy were compared with those of a refiner-free alloy of similar chemical composition. It was found that this level ofthe master alloy addition not only caused an effective grain refinement, but also caused a significant increase in the microhardness ofthe Al-10Mg alloy. Microchemical analysis revealed that TiC particles existed in the grain center. The relationship between the holdingtime and grain size was also studied. It shows that the grain refining efficiency is faded observably with the holding time. This is ex-plained in terms of the instability of TiC particles. | Kuibo Yin Xiufang Bian Na Han Xiujun Yao Yan Zhao Jiankun Zhou | 2006 | Journal of University of Science and Technology Beijing2006，13，2： | 0 |
| 14 | Liquid dynamics and glass formation of Gd_(55)Co_(20)Al_(25)metallic glass with minor Si addition显示文摘Liquid dynamics plays an essential role in glass formation.Here we observed a distinct change of liquid dynamics in Gd_(55)Co_(20)Al_(25)metallic glass induced by microalloying Si element.In the equilibrium melt,minor Si(0.5 at.%)addition leads to a more fragile liquid behavior and a smaller strength of liquid-liquid transition with the transition strength(F)decreasing from 0.76 to 0.35.However,in the supercooled liquid,Si-doped liquid exhibits a remarkable enhanced fragile-to-strong transition(FST),and the value of FST factor f increases sharply from 1.63 to 3.84,resulting in a stronger liquid behavior and more sluggish crystallization kinetics for Gd_(55)Co_(20)Al_(24.5)Si_(0.5)metallic glass.Moreover,minor Si addition promotes the formation of a crystal-like structure with a size of 1-2 nm.The interactions between the crystal-like structures and other local favored clusters frustrate the further growth of crystal-like phases,thus stabilizes the amorphous structure.As a result,the glass-forming ability(GFA)was largely improved.The critical diameter of Gd_(55)Co_(20)Al_(25)metallic glass increased from 2 to 7 mm with 0.5 at.%Si addition without deterioration of the magnetocaloric effect.This study provides valuable insight for understanding the distinct effect of microalloying on GFA of metallic glasses from the aspect of the evolution of the liquid. | Lin Xue Liliang Shao Qiang Luo Lina Hu Yunbo Zhao Kuibo Yin Mingyun Zhu Litao Sun Baolong Shen Xiufang Bian | 2021 | Journal of Materials Science & Technology2021，，18： | 0 |
| 15 | Heterogeneous GdTbDyCoAl high-entropy alloy with distinctive magnetocaloric effect induced by hydrogenation显示文摘Developing novel magnetocaloric materials is of great significance for the applications of magnetic refrigeration.In this study,we designed a heterogeneous rare-earth-based high-entropy alloy(HEA)comprising amorphous matrix,local crystal-like cluster and nanocrystalline dihydride with average size of 7.5 nm through isothermal hydrogenation.This heterogeneous structure can significantly tune the magnetocaloric effect of alloy.After hydrogenation,the predominant exchange interaction transforms from ferromagnetic to antiferromagnetic with the disappearance of spin-glass-like behavior,and a complete second-order magnetic transition is obtained.Compared with the Gd_(20)Tb_(18)Dy_(18)Co_(20)Al_(24) high-entropy metallic glass with a small number of nanocrystals,the maximum magnetic entropy change of the hydrogen-containing HEA is increased from 8.8 to 13.6 J kg^(-1)K^(-1) under applied magnetic field change of 5 T accompanying unobvious hysteresis and decreased magnetic transition temperature from 59 to 8 K,which is more promising as magnetic refrigerant at cryogenic temperature.This work provides a novel concept of designing heterogeneous structure in terms of special cluster and preferential nanocrystalline to modulate the properties of metallic glasses. | Liliang Shao Lin Xue Qiang Luo Kuibo Yin Zirui Yuan Mingyun Zhu Tao Liang Qiaoshi Zeng Litao Sun Baolong Shen | 2022 | Journal of Materials Science & Technology2022，，14： | 0 |
| 16 | Self-supporting, eutectic-like, nanoporous biphase bismuth-tin film for high-performance magnesium storage显示文摘Magnesium ion batteries are emerging as promising alternatives to lithium ion batteries because of their advantages including high energydensity,dendrite-free features and low cost.Nevertheless,one of the major challenges for magnesium ion batteries is the kinetically sluggishmagnesium insertion/extraction and diffusion in electrode materials.Aiming at this issue,biphase eutectic-like bismuth-tin film is designedherein to construct a self-supporting anode with interdigitated phase distribution and hierarchically porous structure,and further fabricated bya facile one-step magnetron cosputtering route.As benchmarked with single-phase bismuth or tin film,the biphase bismuth-tin film delivershigh specific capacity (538 mAh/g at 50 mA/g),excellent rate performance (417 mAh/g at 1,000 mA/g) and good cycling stability (233 mAh/gat the 200th cycle).The superior magnesium storage performance of the sputtered bismuth-tin film could be attributed to the synergetic effectof the interdigitated bismuth/tin phase distribution,hierarchically porous structure and biphase buffering matrices,which could increase ionictransport channels,shorten diffusion lengths and reduce total volume changes. | Meijia Song Jiazheng Niu Kuibo Yin Hui Gao Chi Zhang Wensheng Ma Fakui Luo Zhangquan Peng Zhonghua Zhang | 2019 | Nano Research2019，12，4： | 0 |
| 17 | 深度调峰工况下外圈配水湿式冷却塔模拟研究显示文摘为了提升火电机组冷端系统在深度调峰状态下运行的经济性,本文以冷端辅助设备冷却塔为切入点,分别建立了凝汽器、循环水泵功耗模型和自然通风湿式冷却塔的数值模拟模型,提出了调峰工况下冷却塔外圈配水的运行方式并进行模拟研究。经研究发现,与全塔配水的运行方式相比,采用外圈配水的冷却塔,在循环水流量较低时,其出塔水温较低,冷却塔的通凤量较大;此外,出塔水温会随着环境温湿度和液滴粒径的减小而下降,外圈配水的出塔水温相较更低,对湿度的敏感性较小。最后,结合实际运行数据,对外圈配水运行方式进行经济性分析。结果表明,与全塔配水相比,在负荷低于44.2%额定负荷时,外圈配水冷却塔在单台低速泵运行的情况下其净收益功较高,最高可达0.125 MW。 | 王锁斌 邓彤天 王红波 李晨宇 WU Kuibo | 2020 | 电力大数据2020，23，8： | 0 |
| 18 | Combining in-situ TEM observations and theoretical calculation for revealing the thermal stability of CeO_(2) nanoflowers显示文摘The thermal stability of Ce_(2) nanomaterials can directly impact both the uniformity of the supported catalysts and the catalytic behavior of Ce_(2) itself.However,knowledge about the thermal stability of Ce_(2) is still deficient.Here,we conduct in-situ transmission electron microscopy experiments and theoretical calculations to elucidate the thermal stability of Ce_(2) nanomaterials under different environments.A sinter(<700℃)and a structural decomposition(>700℃)are observed within Ce_(2) nanoflowers under O_(2).The sinter firstly occurs among the nanoflowers’monomers and then the sintered nanoparticles structurally decompose to tiny nanoparticles from the strain interface.Under a vacuum environment,the Ce_(2) nanoflowers firstly undergo a transition from cubic fluorite Ce_(2) to hexagonal Ce_(2)O_(3),accompanied by the oxygen release.The Ce_(2)O_(3) nanoparticles further atomically sublimate from the edges to the center under high temperatures.Theoretical calculation results reveal a considerably lower energy barrier for the structural decomposition under O_(2) and for the sublimation under vacuum.This work provides a perspective on the structural design and performance optimization of Ce_(2)-based catalysts. | Mingyun Zhu Kuibo Yin Yifeng Wen Shugui Song Yuwei Xiong Yunqian Dai Litao Sun | 2022 | Nano Research2022，15，2： | 0 |
