| 1 | Amorphous M0S2 confined in nitrogen-doped porous carbon for improved electrocatalytic stability toward hydrogen evolution reaction显示文摘Developing non-precious metal catalysts with high activity and stability for electrochemical hydrogen evolution reaction(HER)is of great significance in both scie nee and tech no logy.In this work,N-doped CMK-3,which was prepared with a casting method using SBA-15 as thehard template and ammonia as the nitrogen source,has been utilized to hold MoS2 and restrict its growth to form MoS2@N-CMK-3 composite.As a result,M0S2 was found to have poorly crystallized and the limited space of porous N-CMK-3 made its size much small.Then there are moreactive sites in MoS2.Accordingly,MoS2@N-CMK-3 has exhibited good electrocatalytic performance toward HER in acids with a quite small Tafelslope of 32 mV·dec^-1.And more importantly,compared to MoS2@CMK-3,its stability has been greatly improved,which can be attributedto the interaction between M0S2 and nitrogen atoms avoiding aggregation and mass loss.This work provides an idea that doping a porouscarbon support with nitrogen is an effective way to enhance the stability of the catalyst. | Shaojie Lu Wenjing Wang Shengshuang Yang Wei Chen Zhongbin Zhuang Wenjing Tang Caihong He Jiajing Qian Dekun Ma Yun Yang Shaoming Huang | 2019 | Nano Research2019，12，12： | 2 |
| 2 | High-velocity impact responses of 2618 aluminum plates for engine containment systems under combined actions of projectile form and oblique angle显示文摘Ballistic impact tests were carried out with examined projectiles of the Ti-6Al-4V titanium alloy to investigate the impact response of the 2618 aluminum plates at a nominal velocity of 210 m/s. The influence of projectile forms and oblique angles on damage formation was particularly discussed by applying different loading conditions such as multiple projectile forms and oblique angles. Additionally, the numerical simulation method was employed to provide further insight into the characteristics of damage and target responses. The Johnson-Cook(J-C)constitutive model with revised failure parameters was used to support the simulations to assess target responses and characteristics of the damage created from different impact conditions. Results show that there is a significant transition in the deformation mode as changes of the projectile form are applied. Moreover, the cracks on the back of the 2618 aluminum alloy plates impacted by the solid plate projectile and the hollow blade projectile tend to locate at different positions, which are supposed to be influenced by local bending and stretching. The work in this paper may provide guidance for the design of fan blade containment systems. | Cunxian WANG Tao SUO Yulong LI Pu XUE Zhongbin TANG | 2019 | Chinese Journal of Aeronautics2019，32，6： | 2 |
| 3 | Temperature Effect on the Mechanical Behavior of Acrylic Polymers under Quasi-static and Dynamic Loading显示文摘In this paper, the mechanical behavior of acrylic polymers at elevated temperature was investigated. Four acrylic polymers were tested at high strain rate by using compression Hopkinson bar and at quasi-static strain rate by using an Instron servo hydraulic axial testing machine with the testing temperature from 218K to 393K. The results show that the mechanical property of acrylic polymers depends heavily on the testing temperature. The yield stress and Young's modulus were found to decrease with increasing temperature at low strain rate. At very low temperature, the materials display typical brittle fracture; however their plasticity improves remarkably at high temperatures. The predictions of the mechanical behavior including the effect of temperature and strain rate using a proposed theoretical model have a good agreement with experimental results. | Tao Suo Yulong Li Hong Yu Fei Xu Zhongbin Tang Lei Li | 2004 | 上海交通大学学报2004，38，z2： | 2 |
| 4 | TEMPERATURE SENSITIVITY AND PREDICTION OF THE MECHANICAL BEHAVIORS OF ULTRAFINE GRAINED ALUMINUM UNDER UNIAXIAL COMPRESSION显示文摘In the present work, we explore the strain hardening behaviors as well as the effect of temperature on the plastic deformation of ultrafine grained aluminum. The temperature sensitivity is determined and compared with that of coarse grained material. The results indicate that the flow stress of ultrafine grained aluminum displays enhanced sensitivity to temperature. The reduction in activation volume is suggested to be the major reason for the enhanced temperature sensitivity as grain size is refined into the sub-micrometer regime. Finally, a phenomenological constitutive model is proposed to describe the post-yield response of ultrafine grained aluminum. | Quanwei Zhan Tao Suo Cunxian Wang Kui Xie Zhongbin Tang | 2014 | Acta Mechanica Solida Sinica2014，27，4： | 2 |

| 7 | Optimization of synergistic energy storage density and efficiency for eco-friendly (Na_(0.5)Bi_(0.5))_(0.6)Sr_(0.4)TiO_(3)-based relaxor ferroelectric ceramics显示文摘Inspired by increasing demand of advanced pulsed power capacitors,the development of lead-free dielectric ceramic capacitors with high energy storage density and temperature-insensitive performance are extremely crucial.Herein,the lead-free relaxor ferroelectric ceramics based on(1-x)(Na_(0.5)Bi_(0.5))0.6Sr_(0.4)TiO_(3-x)Sr_(0.7)La_(0.2)ZrO_(3)[abbreviated as(1-x)NBST-xSLZ]are prepared by the solid-state reaction route.The large recoverable energy density(Wrec)of 3.45 J/cm^(3) and efficiency(h)of 90.1%are simultaneously realized in 0.86NBST-0.14SLZ ceramic due to increased breakdown strength.Furthermore,both the Wrec and h of 0.86NBST-0.14SLZ ceramic display superior of thermal stability(20e180C),frequency stability(1e1000 Hz),and cycle stability(10^(4))within a satisfactory range of variation.In addition,the 0.86NBST-0.14SLZ ceramic can also achieve a large current density(CD)of 625 A/cm^(2),an ultrahigh power density(PD)of 50 MW/cm^(3) and a fast discharge rate(t0.90)of 160.8 ns at 160 kV/cm.These results demonstrate that the 0.86NBST-0.14SLZ ceramic could be a highly competitive and ecofriendly relaxor ferroelectric material for next-generation pulsed power capacitors. | Hu Di Pan Zhongbin Wu Lukang Yang Fan Tang Luomeng Zhao Jinghao Shen Yihao Chen Yuyun Li Peng Zhai Jiwei Liu Jinjun | 2021 | Journal of Materiomics2021，7，4： | 0 |
| 8 | Disturbance of plateau zokor-made mound stimulates plant community regeneration in the Qinghai-Tibetan Plateau, China显示文摘Mounds constructed by plateau zokors,which is widely distributed in alpine meadows significantly modified plant community structure.However,the variations of plant community structure under the disturbance of plateau zokor-made mound are less concerned.Therefore,we investigated the responses of plant community on zokor-made mound of different years(1 a and 3-4 a),and compared with undisturbed sites(no mound)in an alpine meadow in the eastern Qinghai-Tibetan Plateau(QTP),China.Species richness,coverage and Simpson diversity index were all significantly reduced by the presence of zokor-made mound,but plant heights were significantly increased,particularly in grasses and sedges.Several perennial forage species showed an increased importance value and niche breadth,including Koeleria macrantha,Elymus nutans and Poa pratensis.The effect of zokor-made mound on niche overlap showed that more intense interspecific competition produced a greater utilization of environmental resources.And this interspecific niche overlap was strengthened as succession progressed.The bare mound created by zokor burrowing activities provided a colonizing opportunity for non-dominant forage species,resulting in abundant plant species and plant diversity during the succession period.We concluded that presence of zokor-made mound was conducive to regeneration and vitality of plant community in alpine meadows,thus improving their resilience to anthropogenic stress. | XIANG Zeyu Arvind BHATT TANG Zhongbin PENG Yansong WU Weifeng ZHANG Jiaxin WANG Jingxuan David GALLACHER ZHOU Saixia | 2021 | Journal of Arid Land2021，13，10： | 0 |
| 9 | Effects of surface topography and specimen thickness on high-speed raindrop impact damage of CFRP laminates显示文摘Raindrop impact erosion has been observed since early days of aviation,and can be catastrophic for exposed materials during supersonic flight.A single impact waterjet apparatus is established for mimicking drop impacts at the velocities between 350 m/s and 620 m/s.Carbon Fiber Reinforced Polymer(CFRP)laminates with three different surface morphologies and specimen thicknesses are tested here.A central region with no visible damage has been noticed,surrounded by a'failure ring'with common damage patterns including resin removal,matrix cracking,fiber breakage and mass fiber loss.Asymmetric features are presented in the'failure ring'whose whole scope extends larger along the longitudinal direction than the transverse direction of the top layer.The mechanism of the resin removal is related to fiber-matrix debonding,and its onset and propagation can be facilitated by initial surface asperities with the shear action of the lateral jetting.In cases of multiple impact,good surface quality can slow down the evolution of resin removal and fiber exposure on the CFRP surface,reducing the erosion speed and delaying the occurrence of structural damages in the subsequent impacts.Rayleigh wave dominates the occurrence of matrix cracking on the CFRP surface,and subsequently,results in material loss and peeling of the top-layer because of lateral flow.With the increase of the specimen thickness,both the interlaminar and intralaminar failures decrease as the impact damage mechanism changes from plate bending stress to the reflection of stress waves. | Naidan HOU Renxi ZHAO Xuan WANG Zhongbin TANG Hao CUI Yulong LI | 2023 | Chinese Journal of Aeronautics2023，36，6： | 0 |
| 10 | Excellent thermal stability and high energy storage performances of BNT-based ceramics via phase-structure engineering显示文摘Herein,a novel strategy for regulating the phase structure was used to significantly enhance the recoverable energy storage density(Wrec)and the thermal stability via designing the(1-x)[(Bi_(0.5)Na_(0.5))_(0.7)Sr_(0.3)TiO_(3)]-xBiScO_(3)((1-x)BNST-xBS)relaxor ferroelectric ceramics.The incorporation of BS into BNST ceramics markedly increases the local micro-structure disorder,causing a high polarization and inhibiting polarization hysteresis for 0.95BNST-0.05BS ceramics,leading to a large Wrec of 5.41 J/cm^(3)with an ideal efficiency(h)of 78.5%.Meanwhile,transmission electron microscope(TEM)results further proved that the nano-domain structure and the tetragonal(P4bm)phase superlattice structure of 0.95BNST-0.05BS ceramics possess an excellent thermal stability(20-200℃).An outstanding Wrec value of 3.18×(1.00±0.03)J/cm^(3)and an h value of 74.500±0.025 are achieved under a temperature range from 20℃to 200℃.This work provides a promising method for phase-structure design that can make it possible to apply temperature-insensitive ceramic dielectrics with a high energy storage density in harsh environments. | Mingkun Wang Tian Bai Aina He Zhongbin Pan Jinghao Zhao Luomeng Tang Zhihe Zhao Jinjun Liu Shushuang Li Weixing Xia | 2023 | Journal of Materiomics2023，9，6： | 0 |
| 11 | Enhanced energy-storage performance in BNT-based lead-free dielectric ceramics via introducing SrTi_(0.875)Nb_(0.1)O_(3)显示文摘Environmentally friendly lead-free ceramics capacitors,with outstanding power density,rapid charging/discharging rate,and superior stability,have been receiving increasing attention of late for their ability to meet the critical requirements of pulsed power devices in low-consumption systems.However,the relatively low energy storage capability must be urgently overcome.Herein,this work reports on leadfree SrTi_(0.875)Nb_(0.1)O_(3)(STN)replacement of(Bi_(0.47)La_(0.03)Na_(0.5))_(0.94)Ba_(0.06)TiO_(3)(BLNBT)ferroelectric ceramics with excellent energy storage performance.Improving relaxor behaviour and breakdown strength(Eb),decreasing grain size,and mitigating large polarization difference are conductive to the enhancement of comprehensive energy storage performances.The phase-field simulation methods are further analysized evolution process of electrical tree in the experimental breakdown.In particular,the 0.70BLNBT-0.30STN ceramic exhibit a large discharged energy density of 4.2 J/cm^(3) with an efficiency of 89.3%at room temperature under electric field of 380 kV/cm.Additionally,for practical applications,the BLNBT-based ceramics achieve a high power density(~62.3 MW/cm^(3))and fast discharged time(~148.8 ns)over broad temperature range(20-200℃).Therefore,this work can provide a simple and effective guideline paradigm for acquiring high-performance dielectric materials in low-consumption systems operating in a wide range of temperatures and long-term operations. | Lukang Wu Luomen Tang Yizan Zhai Yiling Zhang Jianjian Sun Di Hu Zhongbin Pan Zhen Su Yang Zhang Jinjun Liu | 2022 | Journal of Materiomics2022，8，3： | 0 |
