| 1 | Topological domain states and magnetoelectric properties in multiferroic nanostructures显示文摘Multiferroic nanostructures have been attracting tremendous attention over the past decade, due to their rich cross-coupling effects and prospective electronic applications. In particular, the emergence of some exotic phenomena in size-confined multiferroic systems, including topological domain states such as vortices, center domains, and skyrmion bubble domains, has opened a new avenue to a number of intriguing physical properties and functionalities, and thus underpins a wide range of applications in future nanoelectronic devices. It is also highly appreciated that nano-domain engineering provides a pathway to control the magnetoelectric properties, which is promising for future energy-efficient spintronic devices. In recent years, this field, still in its infancy, has witnessed a rapid development and a number of challenges too.In this article, we shall review the recent advances in the emergent domain-related exotic phenomena in multiferroic nanostructures. Specific attention is paid to the topological domain structures and related novel physical behaviors as well as the electric-field-driven magnetic switching via domain engineering. This review will end with a discussion of future challenges and potential directions. | Guo Tian Wenda Yang Deyang Chen Zhen Fan Zhipeng Hou Marin Alexe Xingsen Gao | 2019 | National Science Review2019，6，4： | 4 |
| 2 | Centrifuge experiment on the penetration test for evaluating undrained strength of deep-sea surface soils显示文摘Rapid advances in deep-sea mining engineering have created an urgent need for the accurate evaluation of the undrained strength of marine soils,especially surface soils.Significant achievements have been made using full-flow penetration penetrometers to evaluate marine soil strength in the deep penetration;however,a method considering the effect of ambient water on the surface penetration needs to be established urgently.In this study,penetrometers with multiple probes were developed and used to conduct centrifuge experiments on South China Sea soil and kaolin clay.First,the forces on the probes throughout the penetration process were systematically analyzed and quantified.Second,the spatial influence zone was determined by capturing the resistance changes and sample crack development,and the penetration depth for a sample to reach a stable failure mode was given.Third,the vane shear strength was used to invert the penetration resistance factor of the ball and determine the range of the penetration resistance factor values.Furthermore,a methodology to determine the penetration resistance factors for surface marine soils was established.Finally,the effect of the water cavity above various probes in the surface penetration was used to formulate an internal mechanism for variations in the penetration resistance factor. | Xingsen Guo Tingkai Nian Wei Zhao Zhongde Gu Chunpeng Liu Xiaolei Liu Yonggang Jia | 2022 | International Journal of Mining Science and Technology2022，32，2： | 2 |

| 5 | Ferroelectricity in dopant-free HfO_(2) thin films prepared by pulsed laser deposition显示文摘As a high-k material,hafnium oxide(HfO_(2))has been used in gate dielectrics for decades.Since the discovery of polar phase in Si-doped HfO_(2) films,chemical doping has been widely demonstrated as an effective approach to stabilize the ferroelectric phase in HfO_(2) based thin films.However,the extra capping layer deposition,post-growth annealing and wake-up effect are usually required to arouse the ferroelectricity in HfO_(2) based thin films,resulting in the increase of complexity for sample synthesis and the impediment of device application.In this study,the ferroelectricity is observed in non-capped dopant-free HfO_(2) thin films prepared by pulsed laser deposition(PLD)without post-growth annealing.By adjusting the deposited temperature,oxygen pressure and thickness,the maximum polarization up to 14.7 m C/cm^(2) was obtained in 7.4 nm-thick film.The fraction of orthorhombic phase,concentrations of defects and size effects are considered as possible mechanisms for the influences of ferroelectric prop-erties.This study indicates that PLD is an effective technique to fabricate high-quality ferroelectric HfO_(2) thin films in the absence of chemical doping,capping layer deposition and post-growth annealing,which may boost the process of nonvolatile memory device application. | Yongjian Luo Zhenxun Tang Xiaozhe Yin Chao Chen Zhen Fan Minghui Qin Min Zeng Guofu Zhou Xingsen Gao Xubing Lu Jiyan Dai Deyang Chen Jun-Ming Liu | 2022 | Journal of Materiomics2022，8，2： | 1 |

| 14 | Predicting impact forces on pipelines from deep-sea fluidized slides:A comprehensive review of key factors显示文摘Deep-sea pipelines play a pivotal role in seabed mineral resource development,global energy and resource supply provision,network communication,and environmental protection.However,the placement of these pipelines on the seabed surface exposes them to potential risks arising from the complex deep-sea hydrodynamic and geological environment,particularly submarine slides.Historical incidents have highlighted the substantial damage to pipelines due to slides.Specifically,deep-sea fluidized slides(in a debris/mud flow or turbidity current physical state),characterized by high speed,pose a significant threat.Accurately assessing the impact forces exerted on pipelines by fluidized submarine slides is crucial for ensuring pipeline safety.This study aimed to provide a comprehensive overview of recent advancements in understanding pipeline impact forces caused by fluidized deep-sea slides,thereby identifying key factors and corresponding mechanisms that influence pipeline impact forces.These factors include the velocity,density,and shear behavior of deep-sea fluidized slides,as well as the geometry,stiffness,self-weight,and mechanical model of pipelines.Additionally,the interface contact conditions and spatial relations were examined within the context of deep-sea slides and their interactions with pipelines.Building upon a thorough review of these achievements,future directions were proposed for assessing and characterizing the key factors affecting slide impact loading on pipelines.A comprehensive understanding of these results is essential for the sustainable development of deep-sea pipeline projects associated with seabed resource development and the implementation of disaster prevention measures. | Xingsen Guo Ning Fan Defeng Zheng Cuiwei Fu Hao Wu Yanjun Zhang Xiaolong Song Tingkai Nian | 2024 | International Journal of Mining Science and Technology2024，34，2： | 0 |
| 15 | Structural, magnetic behaviors and temperature-dependent Raman scattering spectra of Y and Zr codoped BiFeO_(3) ceramics显示文摘Multiferroic BiFeO_(3)(BFO)and Y,Zr codoped BFO(Bi_(1-x)Y_(x)Fe_(0.95)Zr_(0.05)O_(3)ceramics were prepared and the influence of codoping on the crystal structure and magnetic properties were investigated in this work.Confirmed by the evolution of X-ray diffraction and Raman modes,the codoping has changed the crystal structure from rhombohedral to tetragonal in bulk BFO ceramics.The enhancement of magnetic behaviors is demonstrated by the damage of space-modulated spiral spin structure,and it can be attributed to the crystal structure change and size effects.Meanwhile,Raman spectra from 300 to 800K demonstrates that lower frequency phonon modes show rapid softening near the Neel temperature. | Cheng Zhang Dan Xie Jianlong Xu Yilin Sun Yongyuan Zang Xiaowen Zhang Xingsen Gao | 2015 | Journal of Advanced Dielectrics2015，5，3： | 0 |
| 16 | Versatile SrFeO_(x) for memristive neurons and synapses显示文摘Spiking neural network(SNN)consisting of memristor-based artificial neurons and synapses has emerged as a compact and energy-efficient hardware solution for spatiotemporal information processing.However,it is challenging to develop memristive neurons and synapses based on the same material system because the required resistive switching(RS)characteristics are different.Here,it is shown that SrFeO_(x)(SFO),an intriguing material system exhibiting topotactic phase transformation between insulating brownmillerite(BM)SrFeO_(2).5 phase and conductive perovskite(PV)SrFeO_(3) phase,can be engineered into both neuronal and synaptic devices.Using a BM-SFO single layer as the RS medium,the Au/BM-SFO/SrRuO_(3)(SRO)memristor exhibits nonvolatile RS behavior originating from the formation/rupture of PV-SFO filaments in the BM-SFO matrix.By contrast,using a PV-SFO(matrix)/BM-SFO(interfacial layer)bilayer as the RS medium,the Au/PV-SFO/BM-SFO/SRO memristor exhibits volatile RS behavior originating from the interfacial BM-PV phase transformation.Synaptic and neuronal characteristics are further demonstrated in the Au/BM-SFO/SRO and Au/PV-SFO/BM-SFO/SRO memristors,respectively.Using the SFO-based synapses and neurons,fully memristive SNNs are constructed by simulation,which show good performance on unsupervised image recognition.Our study suggests that SFO is a versatile material platform on which both neuronal and synaptic devices can be developed for constructing fully memristive SNNs. | Kaihui Chen Zhen Fan Jingjing Rao Wenjie Li Deming Wang Changjian Li Gaokuo Zhong Ruiqiang Tao Guo Tian Minghui Qin Min Zeng Xubing Lu Guofu Zhou Xingsen Gao Jun-Ming Liu | 2022 | Journal of Materiomics2022，8，5： | 0 |
| 17 | Deep seabed mining:Frontiers in engineering geology and environment显示文摘Ocean mining activities have been ongoing for nearly 70 years,making great contributions to industrialization.Given the increasing demand for energy,along with the restructuring of the energy supply catalyzed by efforts to achieve a low-carbon economy,deep seabed mining will play an important role in addressing energy-and resource-related problems in the future.However,deep seabed mining remains in the exploratory stage,with many challenges presented by the high-pressure,low-temperature,and complex geologic and hydrodynamic environments in deep-sea mining areas,which are inaccessible to human activities.Thus,considerable efforts are required to ensure sustainable,economic,reliable,and safe deep seabed mining.This study reviews the latest advances in marine engineering geology and the environment related to deep-sea min-ing activities,presents a bibliometric analysis of the development of ocean mineral resources since the 1950s,summarizes the development,theory,and issues related to techniques for the three stages of ocean mining(i.e.,exploration,extraction,and closure),and discusses the engineering geology environment,geological disasters,in-situ monitoring techniques,envi-ronmental protection requirements,and environmental effects in detail.Finally,this paper gives some key conclusions and future perspectives to provide insights for subsequent studies and commercial mining operations. | Xingsen Guo Ning Fan Yihan Liu Xiaolei Liu Zekun Wang Xiaotian Xie Yonggang Jia | 2023 | International Journal of Coal Science & Technology2023，10，2： | 0 |
| 18 | The Adsorption and Film Forming Behavior of Vinyltriethoxysilane(VS) on Low Carbon Steel Surfaces显示文摘The adsorption and film forming behavior of vinyltriethoxysilane(VS) on Q235 low carbon steel surfaces, as well as its effect on the properties of film layer were systematically investigated by reflection absorption infrared spectrum(RA-IR), electrochemical impedance spectroscopy(EIS) and contact angle measurement technology. The experimental results indicate that the oscillatory phenomenon exists in the adsorption of VS on low carbon steel surfaces, which directly determines the adsorption morphology and the arrangement pattern of VS on metal surfaces, generating VS films with different protective properties. The desorption occurring in the initial stage was accompanied with film restructuring, which was helpful to the readsorption of VS and the film formation with dense structure and excellent protective performance. | 边美华 PENG Jianing YIN Liqun LIANG Qingguo ZHANG Xingsen | 2019 | Journal of Wuhan University of Technology(Materials Science)2019，34，4： | 0 |
| 19 | Experimental search for high-performance ferroelectric tunnel junctions guided by machine learning显示文摘Ferroelectric tunnel junction(FTJ)has attracted considerable attention for its potential applications in nonvolatile memory and neuromorphic computing.However,the experimental exploration of FTJs with high ON/OFF ratios is a challenging task due to the vast search space comprising of ferroelectric and electrode materials,fabrication methods and conditions and so on.Here,machine learning(ML)is demonstrated to be an effective tool to guide the experimental search of FTJs with high ON/OFF ratios.A dataset consisting of 152 FTJ samples with nine features and one target attribute(i.e.,ON/OFF ratio)is established for ML modeling.Among various ML models,the gradient boosting classification model achieves the highest prediction accuracy.Combining the feature importance analysis based on this model with the association rule mining,it is extracted that the utilizations of{graphene/graphite(Gra)(top),LaNiO_(3)(LNO)(bottom)}and{Gra(top),Ca_(0.96)Ce_(0.04)MnO_(3)(CCMO)(bottom)}electrode pairs are likely to result in high ON/OFF ratios in FTJs.Moreover,two previously unexplored FTJs:Gra/BaTiO_(3)(BTO)/LNO and Gra/BTO/CCMO,are predicted to achieve ON/OFF ratios higher than 1000.Guided by the ML predictions,the Gra/BTO/LNO and Gra/BTO/CCMO FTJs are experimentally fabricated,which unsurprisingly exhibit≥1000 ON/OFF ratios(~8540 and~7890,respectively).This study demonstrates a new paradigm of developing high-performance FTJs by using ML. | Jingjing Rao Zhen Fan Qicheng Huang Yongjian Luo Xingmin Zhang Haizhong Guo Xiaobing Yan Guo Tian Deyang Chen Zhipeng Hou Minghui Qin Min Zeng Xubing Lu Guofu Zhou Xingsen Gao Jun-Ming Liu | 2022 | Journal of Advanced Dielectrics2022，12，3： | 0 |
| 20 | Emergent strain engineering of multiferroic BiFeO_(3) thin films显示文摘BiFeO_(3),a single-phase multiferroic material,possesses several polymorphs and exhibits a strong sensitivity to strain.Recently,emergent strain engineering in BiFeO_(3) thin films has attracted intense interest,which can overcome the confines of traditional strain engineering introduced through the mismatch between the film and substrate.In this review,we discuss emerging non-traditional strain engineering approaches to create new ground states and manipulate novel functionalities in multiferroic BiFeO_(3) thin films.Through fabricating freestanding thin films,inserting an interface layer or utilizing thermal expansion mismatch,continuously tunable strain can be imposed beyond substrate limitations.Nanostructured evolution and defect introduction are discussed as efficient routes to introduce strain,promising for the development of new nanodevices.Ultrafast optical excitation,growth conditions and chemical doping driven strain are summarized as well.We hope this review will arouse the readers’interest in this fascinating field. | Fei Sun Deyang Chen Xingsen Gao Jun-Ming Liu | 2021 | Journal of Materiomics2021，7，2： | 0 |
