| 1 | Review of low timing jitter mode-locked fiber lasers and applications in dual-comb absolute distance measurement显示文摘Passively mode-locked fiber lasers emit femtosecond pulse trains with excellent short-term stability. The quantum-limited timing jitter of a free running femtosecond erbium-doped fiber laser working at room temperature is considerably below one femtosecond at high Fourier frequency. The ultrashort pulse train with ultralow timing jitter enables absolute time-of-flight measurements based on a dual-comb implementation, which is typically composed of a pair of optical frequency combs generated by femtosecond lasers. Dead-zone-free absolute distance measurement with sub-micrometer precision and kHz update rate has been routinely achieved with a dual-comb configuration, which is promising for a number of precision manufacturing applications, from large step-structure measurements prevalent in microelectronic profilometry to three coordinate measurements in large-scale aerospace manufacturing and shipbuilding. In this paper, we first review the sub-femtosecond precision timing jitter characterization methods and approaches for ultralow timing jitter mode-locked fiber laser design. Then, we provide an overview of the state-of-the-art dual-comb absolute ranging technology in terms of working principles, experimental implementations, and measurement precisions. Finally, we discuss the impact of quantum-limited timing jitter on the dual-comb ranging precision at a high update rate. The route to highprecision dual-comb range finder design based on ultralow jitter femtosecond fiber lasers is proposed. | Haosen Shi Youjian Song Runmin Li Yuepeng Li Hui Cao Haochen Tian Bowen Liu Lu Chai Minglie Hu | 2018 | Nanotechnology and Precision Engineering2018，1，4： | 9 |
| 2 | In-situ observations of damage-fracture evolution in surrounding rock upon unloading in 2400-m-deep tunnels显示文摘The damage-fracture evolution of deep rock mass has obvious particularity,which is revealed in 2400-mdeep tunnels by field tests.The evolution of the excavation damaged zone depth is consistent with that of the fractured zone depth.The ratio of the excavation damaged zone depth to the excavation fractured zone depth is greater than 2.0 in a rock mass with both high strength and good integrity,but less than1.5 in a rock mass with lower strength or poor integrity.Zonal disintegration in a rock mass with high strength and fair integrity is more likely to occur when it contains more than two groups of primary fractures in damaged zones.Fractures develop outward in zonal disintegration but are totally different from the single-zone fracture,in which the fractures develop inward,and it is the starting position of the fractured zone when the excavation surface of the middle pilot is 7–9 m close to the pre-set borehole and it stops after the excavation surface of the baseplate is 11–14 m away.The most intense evolution occurs around 2–4 m from the pre-set borehole in the sidewall expansion stage.The research results provide a reference for the monitoring scheme and support design of CJPL-Ⅲin its future construction. | Haosen Guo Qiancheng Sun Guangliang Feng Shaojun Li Yaxun Xiao | 2023 | International Journal of Mining Science and Technology2023，33，4： | 5 |
| 3 | Abutment pressure distribution for longwall face mining through abandoned roadways显示文摘Abutment pressure distribution is different when a longwall panel is passing through the abandoned gate roads in a damaged coal seam. According to the geological condition of panel E13103 in Cuijiazhai Coal Mine in China, theoretical analysis and finite element numerical simulation were used to determine the front pressure distribution characteristics when the longwall face is 70, 50, 30, 20, 10, and 5 m from the abandoned roadways. The research results show that the influence range of abutment pressure is 40 to 45 m outby the face, and the peak value of front abutment pressure is related to the distance between the face and abandoned roadways. When the distance between the longwall face and abandoned roadways is reduced from 50 to 10 m, the front abutment pressure peak value kept increasing. When the distance is 10 m, it has reached the maximum. The peak value is located in 5 to 6 m outby the faceline. When the distance between the longwall face and abandoned roadways is reduced from 10 to 5 m, the front abutment pressure sharply decreases, the intact coal yields and is even in plastic state. The peak value transfers to the other side of the abandoned roadways. The research results provide a theoretical basis for determining the advance support distance of two roadways in the panel and the reinforcement for face stability when the longwall face is passing through the abandoned roadways. | Yang Li Mingxing Lei Haosen Wang Cheng Li Weiwei Li Yang Tao Jingyi Wang | 2019 | International Journal of Mining Science and Technology2019，29，1： | 4 |

| 5 | Rapid operando gas monitor for commercial lithium ion batteries: Gas evolution and relation with electrode materials显示文摘Internal gases caused by side reactions are crucial signals for evaluating health and safety states of Li-ion batteries(LIBs)while it is still a great challenge to timely realize accurate monitoring.To address the issues of implanting various gas sensors into commercial batteries,here a novel method is developed to fast operando monitoring gas evolution via equipping non-dispersive infrared multi-gases sensors into a sealed tank,where real commercial batteries with one open end could be settled for operating.The generated CO_(2)concentration is strongly linked with both voltage and temperature,while the concentrations of CH_(4) and C_(2)H_(4) are solely dependent on temperature.As a typical trace gas,evolution behaviors of CO_(2)have been related to 0_(2) generation from LiNi_(o.5)Mn_(0.3)CoO_(2)0_(2) positive electrode,implying stable CO_(2)release below a critical voltage of 4.5 V.By tracking CO_(2)concentration,an increased amount of Li_(2)CO_(3) was monitored on the surface of graphite negative electrode during discharge process at dfferent temperatures and cutoff voltages,which contributes to the component variation of solid electrolyte interfaces.Such operando techniques promise a plaform for well understanding the interaction of side reactions linked with gas evolution between positive and negative electrodes in commercial LIBs. | Siqi Lyu Na Li Lei Sun Shuqiang Jiao Haosen Chen Wei-Li Song | 2022 | Journal of Energy Chemistry2022，31，9： | 3 |
| 6 | Super Na^(+)Half/Full Batteries and Ultrafast Na+Diffusion Kinetics of Cobalt-Nickel Selenide from Assembling Co_(0.5)Ni_(0.5)Se_(2)@NC Nanosheets into Cross-Stacked Architecture显示文摘Explorati on of adva need an ode materials for sodium-i on batteries(SIBs)is still a big challe nge due to the large radius of sodium.In this work,the hierarchical architectures assembled from N-doped carbon-coated Co_(0.5)Ni_(0.5)Se_(2)(Co_(0.5)Ni_(0.5)Se_(2)@NC)nanoparticles encapsulated into cross-stacked nano sheets have been successfully prepared from the cobalt-nickel bin ary-metal organic frameworks(CoNi-MOF)by two steps of the solid-state sele nizati on and carb on coating processes.Imports ntly,the resulta nt hierarchical Co0.5Nio:5Se2@NC architecture can achieve a satisfactory electrochemical performance,maintaining a high-rate capacity of 330 mA-h-g^(-1)1 at 3 A·g^(-1) and a stable cyclability of 100 cycles without obvious capacity decay at 0.2 A·g^(-1).The design of distinct superstructure can not only be applied to other electrode materials but also boost the forward development of energy storage systems. | Zhiyong Li Zilin Peng Rui Sun Zhaoxia Qin Xinlong Liu Caihong Wang Haosen Fan Shengjun Lu | 2021 | Chinese Journal of Chemistry2021，39，9： | 3 |
| 7 | Stable wide-temperature and low volume expansion Al batteries:Integrating few-layer graphene with multifunctional cobalt boride nanocluster as positive electrode显示文摘To achieve stable positive electrode for promoting the overall electrochemical performance of Al batteries(ABs),here novel cobalt boride(CoB)nanoclusters are synthesized to construct composite electrodes with few-layer graphene(FLG).Due to the presence of amorphous channels in the employed CoB nanoclusters,the ABs with FLG/CoB composite positive electrodes exhibit high rate.capability and both mechanical and electrochemical stability in the ABs.With assistance of in situ scanning electron microscopy(SEM),the observation results suggest that the positive electrode of CoB nanoclusters holds almost ignorable volume variation upon electrochemical processes,which substantially alleviates the massive electrode expansion induced by the anion intercalation in the composite positive electrode.Interestingly,the composite positive electrodes provide stable reversible energy storage capability within a broadened temperature range(-30-60℃),promising a novel strategy to design advanced ABs positive electrodes with enhanced overall energy storage performance. | Li-Li Chen Na Li Huifeng Shi Yuefei Zhang Wei-Li Song Shuqiang Jiao Haosen Chen Daining Fang | 2020 | Nano Research2020，13，2： | 2 |

| 9 | Pressure of Newtonian Fluid Flow through Curved Pipes and Elbows显示文摘Under conditions of high temperature and high pressure, the non-uniformity of pressure loads has intensified the stress concentration which impacts the safety of curved pipes and elbows. This paper focuses on the pressure distribution and flow characteristic in a curved 90 o bend pipe with circular cross-sections, which are widely used in industrial applications. These flow and pressure characteristics in curved bend pipes have been researched by employing numerical simulation and theoretical analysis. Based on the dimensionless analysis method a formula for the pressure of Newtonian fluid flow through the elbow pipes is deduced. Also the pressure distributions of several elbows with different curvature ratio R/D are obtained by numerical methods. The influence of these non-dimensional parameters such as non-dimensional curvature ratio, Reynolds number and non-dimensional axial angle α and circumferential angle β on the pressure distribution in elbow pipes is discussed in detail. A number of important results have been achieved. This paper provides theoretical and numerical methods to understand the mechanical property of fluid flow in elbow pipes, to analyze the stress and to design the wall thickness of elbow pipes. | Hao Zhang Xinxin Zhang Haosen Sun Mingjiu Chen Xiaoyang Lu Yuancheng Wang Xueting Liu | 2013 | Journal of Thermal Science2013，22，4： | 2 |
| 10 | Electrochemomechanical coupled behaviors of deformation and failure in electrode materials for lithium-ion batteries显示文摘The growing demands of lithium-ion batteries with high energy density motivate the development of high-capacity electrode materials. The critical issue in the commercial application of these electrodes is electrochemomechanical degradation accompanied with the large volume change, built-in stress, and fracture during lithiation and delithiation. The strong and complex couplings between mechanics and electrochemistry have been extensively studied in recent years. The multi-directional couplings, e.g.,(de)lithiation-induced effects and stress-regulated effects, require cooperation in the interdisciplinary fields and advance the theoretical and computational models. In this review, we focus on the recent work with topics in the electrochemomechanical couplings of deformation and fracture of conventional and alloying electrodes through experimental characterization, theoretical and computational models. Based on the point of view from mechanics, the strategies for alleviating the degradation are also discussed, with particular perspectives for component-interaction patterns in the composite electrodes. With interdisciplinary principles, comprehensive understanding of the electrochemomechanical coupled mechanism is expected to provide feasible solutions for low-cost, high-capacity, high-safety and durable electrodes for lithium-ion batteries. | LIANG HuanZi ZHANG XingYu YANG Le WU YiKun CHEN HaoSen SONG WeiLi FANG DaiNing | 2019 | Science China(Technological Sciences)2019，62，8： | 2 |
| 11 | Thickness evolution of commercial Li-ion pouch cells with siliconbased composite anodes and NCA cathodes显示文摘It is significant to monitor the thickness change of commercial Li-ion pouch cells that are assembled from Si-based electrodes and layered cathodes since the volume variation is critically linked with kinetic reaction mechanism and chemomechanical degradation. In this work, the single-point and full-field measurements are conducted on the thickness evolution of Si Ox/Cgraphite/lithium nickel-cobalt-aluminum oxide(Si Ox-G/NCA) batteries. It is found that an abnormal overshoot that has been rarely observed in the previous studies appears at the beginning of discharge, which is believed to be the combined results between the rapid expansion of NCA and the contraction of graphite related to the state of charge(SOC). Compared with the results of single-point measurement, the spatial displacement distribution obtained from three-dimensional(3D) scanning suggests the full-field thickness evolution of the entire cell scale, which is more feasible and efficient to provide full-field information for supporting pouch cell design and pack integration. | ZHANG XingYu HE Jie ZHOU Jiang CHEN HaoSen SONG WeiLi FANG DaiNing | 2021 | Science China(Technological Sciences)2021，64，1： | 2 |

| 13 | Electrochemically triggered decoupled transport behaviors in intercalated graphite:From energy storage to enhanced electromagnetic applications显示文摘Pyrolytic graphite (PG) with highly aligned graphene layers,present anisotropic electrical and thermal transport behavior,which is attractive in electronic,electrocatalyst and energy storage.Such pristine PG could meeting the limit of electrical conductivity (~2.5×10^(4) S·cm^(−1)),although efforts have been made for achieving high-purity sp^(2) hybridized carbon.For manipulating the electrical conductivity of PG,a facile and efficient electrochemical strategy is demonstrated to enhance electrical transport ability via reversible intercalation/de-intercalation of AlCl_(4)^(-)into the graphitic interlayers.With the stage evolution at different voltages,variable electrical and thermal transport behaviors could be achieved via controlling AlCl_(4)^(-)concentrations in the PG because of substantial variation in the electronic density of states.Such evolution leads to decoupled electrical and thermal transport (opposite variation trend) in the in-plane and out-of-plane directions,and the in-plane electrical conductivity of the pristine PG (1.25×10^(4) S·cm^(−1)) could be massively promoted to 4.09×10^(4) S·cm(AlCl_(4)^(-)intercalated PG),much better than the pristine bulk graphitic papers used for the electrical transport and electromagnetic shielding.The fundamental mechanism of decoupled transport feature and electrochemical strategy here could be extended into other anisotropic conductive bulks for achieving unusual behaviors. | Ya Chen Kailun Zhang Na Li Wei Guan Zhiyuan Li Haosen Chen Shuqiang Jiao Weili Song | 2023 | International Journal of Minerals,Metallurgy and Materials2023，30，1： | 1 |
| 14 | Initial Electrode Kinetics of Anion Intercalation and De-intercalation in Nonaqueous Al-Graphite Batteries显示文摘Graphitic materials with intercalated sites are considered as the mostly used positive electrode materials in nonaqueous Al batteries.Unlike the small-size cations,the intercalation/de-intercalation of large-size anions into/out of graphite would induce large volume expansion and micro-structure reconfiguration,leading to unexpected coulombic efficiency in the full cells(<95%within initial several cycles). | Dan Han Mao-Sheng Cao Na Li Dong-Mei She Wei-Li Song Haosen Chen Shuqiang Jiao Daining Fang | 2021 | Chinese Journal of Chemistry2021，39，1： | 1 |
| 15 | Thickness evolution of graphite-based cathodes in the dual ion batteries via in operando optical observation显示文摘Graphite has been currently considered as a promising cathode material in dual ion batteries(DIBs)due to its unique features of sp2 hybridized carbon and stacked two-dimensional layered structures.However,unexpected volume/thickness changes in the graphite cathodes,induced by the intercalation/deintercalation of anions with large molecular size have been known to be a critical problem in designing DIB cells.To understand the volume/thickness changes in the DIB electrodes,in operando optical observing apparatus has been employed to observe the cross-section view of a graphite-based cathode upon cycles in the present work.The observation suggests that the cathode initially presented a huge irreversible thickness change(60%),and such thickness variation was prone to reduce and remain <20% in the following cycles.The results from both in operando observation and electrochemical characterizations collectively indicate that the greater thickness variation at initial cycle should be attributed to both anion intercalation into graphite-based cathodes and irreversible decomposition of chemical components in the DIB system.The method here highlights a universal route for fundamentally understanding the electrodes of huge volume variation. | Na Li Yaoda Xin Haosen Chen Shuqiang Jiao Hanqing Jiang Wei-Li Song Daining Fang | 2019 | Journal of Energy Chemistry2019，28，2： | 1 |

| 17 | Al homogeneous deposition induced by N-containing functional groups for enhanced cycling stability of Al-ion battery negative electrode显示文摘Rechargeable Al-ion batteries(AIBs)are considered as one of the most fascinating energy storage systems due to abundant Al resource and low cost.However,the cycling stability is subjected to critical problems for using Al foil as negative electrode,including Al dendrites,corrosion and pulverization.For addressing these problems,here a lightweight self-supporting N-doped carbon rod array(NCRA)is demonstrated for a long-life negative electrode in AIBs.Experimental analysis and first-principle calculations reveal the storage mechanism involving the induced deposition of N-containing function groups to Al as well as the ideal skeleton of the NCRA matrix for Al plating/stripping,which is favorable for regulating Al nucleation and suppressing dendrites growth.Compared with the Al foil,the NCRA exhibits lower areal mass density(∼72%of Al foil),smaller thickness(40%of Al foil),but much longer cycle life(>4 times of Al foil).Benefiting from the remarkable stability of the array structure,symmetric cells show excellent cycling stability with small voltage hysteresis(∼80 mV)and meanwhile there are no corrosion and pulverization problems even after cycled for 120 hours.Besides,full cells also manifest long lifespan(1,500 cycles)and increased Coulombic efficiency(100±1%). | Handong Jiao Shuqiang Jiao Wei-Li Song Xiang Xiao Dongmei She Na Li Haosen Chen Jiguo Tu Mingyong Wang Daining Fang | 2021 | Nano Research2021，14，3： | 1 |
| 18 | Electrochemical and Pseudocapacitive Analysis of Rod-Like MoO_(2)@MoSe_(2)@NC Heterostructures for High-Performance Lithium Ion Batteries显示文摘A micro-scale rod-like heterostructure derived from molybdenum-based metal organic framework(Mo-MOF)has been successfully prepared via subsequent annealing treatment,which assembled from N-doped carbon encapsulated MoSe_(2) nanosheets grown on the surface of MoO_(2) microrod(named as MoO_(2)@MoSe_(2)@NC).For this novel heterostructure,the MoO_(2) nanoparticles assembled into rod core not only serve as supporting substrate for facilitating the fast kinetics of Li+cations inside the electrode but also protect the MoSe_(2) structure from restacking in the charge/discharge process.Moreover,the outer-layered MoSe2 nanosheets enable the fast lithium ion movement owing to its large interlayer spacing.Moreover,this unique rod-like core-shell structure composite could further effectively alleviate the structural strains caused by large volume expansion during charge/discharge process,thus leading to stable electrochemical performance when evaluated as anode material for lithium ion batteries.Electrochemical testing exhibits that the MoO_(2)@MoSe_(2)@NC heterostructure presents highly reversible capacity of 468 mAh g^(-1)at 0.5 A g^(-1)and superior rate capability(318 mAh g^(-1)even at 5.0 A g^(-1)),which is attributed to the synergistic effect of N-doped carbon encapsulated MoSe2 nanosheets and MoO_(2) nanoparticles. | Zhaoxia Qin Xinlong Liu Zhiyin Huang Rui Sun Zhiyong Li Haosen Fan Shengjun Lu | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，3： | 1 |
| 19 | Synthesis of Metal Oxides@C(Metal=Ni,Fe) Based Prussian Blue Analogs as a High-performance Anode Material for Lithium-ion Battery显示文摘Ni3[Fe(CN)6]2 nano-cubic precursors were prepared by chemical coprecipitation at room temperature with nickel acetate and potas sium ferricyanide as raw materials.The corresponding NiFe2O4-NiO@C composites with excellent crystallization were prepared by two-stage oxidation at low temperature.The microstructure and electrochemical behavior of the materials showed that the Prussian blue analog was transformed into metal oxide while the carbon coating was maintained in the twostage oxidation at low temperature.The existence of the carbon coating reduces the charge transfer impedance to 31.5 Ω.At the current density of 500 mA/g,the reversible capacity of 632.7 mAh/g is maintained after 500 cycles.At the same time,carbon cladding can also enhance the role of pseudocapacitance in the material.At the scanning rate of 0.1 mV/s,the pseudocapacitance account for 54.4% of the total discharge capacity,which is significantly higher than that of uncoated materials. | Wei Yang Xiaoxian Pang Zhao Xue Jinhao Ye Haosen Fan Ting Shu Wenzhi Zheng Shengzhou Chen | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，3： | 1 |
| 20 | Synthesis of Hollow Three-Dimensional Channels LiNi_(0.5)Mn_(1.5)O_4 Microsphere by PEO Soft Template Assisted with Solvothermal Method显示文摘A appropriate size with three-dimension(3 D) channels for lithium diffusion plays an important role in constructing highperforming LiNi_(0.5)Mn_(1.5)O_4(LNMO) cathode materials, as it can not only reduce the transport path of lithium ions and electrons, but also reduce the side effects and withstand the structural strain in the process of repetitive Li~+ intercalation/deintercalation. In this work, an e fficient method for designing the hollow LNMO microsphere with 3 D channels structure by using polyethylene oxide(PEO) as soft template agent assisted solvothermal method is proposed. Experimental results indicate that PEO can make the reagents mingle evenly and nucleate slowly in the solvothermal process, thus obtaining a homogeneous distribution of carbonate precursors. In the final LNMO products, the hollow 3 D channels structure obtained by the decomposition of PEO and carbonate precursor in the calcination can provide abundant electroactive zones and electron/ion transport paths during the charge/discharge process, which benefits to improve the cycling performance and rate capability. The LNMO prepared by adding 1 g PEO possesses the most outstanding electrochemical performance, which presented an excellent discharge capacity of 143.1 mAh g~(-1) at 0.1 C and with a capacity retention of 92.2% after 100 cycles at 1 C. The superior performance attributed to the 3 D channels structure of hollow microspheres, which provide uninterrupted conductive systems and therefore achieve the stable transfer for electron/ion. | Jinfeng Zeng Zhiting Liu Hanbo Zou Wei Yang Haosen Fan Haijun Yu Shengzhou Chen | 2021 | Acta Metallurgica Sinica(English Letters)2021，34，8： | 1 |
