| 1 | Room temperature ferromagnetism in ultra-thin van der Waals crystals of 1T-CrTe2显示文摘Although many emerging new phenomena have been unraveled in two dimensional(2D)materials with long-range spin orderings,the usually low critical temperature in van der Waals(vdW)magnetic material has thus far hindered the related practical applications.Here,we show that ferromagnetism can hold above 300 K in a metallic phase of 1T-CrTe2 down to the ultra-thin limit.It thus makes CrTe2 so far the only known exfoliated ultra-thin vdW magnets with intrinsic long-range magnetic ordering above room temperature.An in-plane room-temperature negative anisotropic magnetoresistance(AMR)was obtained in ultra-thin CrTe2 devices,with a sign change in the AMR at lower temperature,with−0.6%and+5%at 300 and 10 K,respectively.Our findings provide insights into magnetism in ultra-thin CrTe2,expanding the vdW crystals toolbox for future room-temperature spintronic applications. | Xingdan Sun Wanying Li Xiao Wang Qi Sui Tongyao Zhang Zhi Wang Long Liu Da Li Shun Feng Siyu Zhong Hanwen Wang Vincent Bouchiat Manuel Nunez Regueiro Nicolas Rougemaille Johann Coraux Anike Purbawati Abdellali Hadj-Azzem Zhenhua Wang Baojuan Dong Xing Wu Teng Yang Guoqiang Yu Bingwu Wang Zheng Han Xiufeng Han Zhidong Zhang | 2020 | Nano Research2020，13，12： | 6 |

| 4 | Seismogenic tectonics of the Qian-Gorlos earthquake in Jilin Province,China显示文摘The Qian-Gorlos earthquake, which occurred in the Songliao basin in Jilin Province in 1119 AD, was the largest earthquake to occur in NE China before the 1975 Haicheng earthquake. Based on historical records and surface geological investigations, it has been suggested previously that the earthquake epicenter was in the Longkeng area. However, other workers have considered the epicenter to be in the Halamaodu area based on the landslides and faults found in this region. No seismogenic structure has yet been found in either of these two regions.We tried to detect active faults in the urban areas of Songyuan City, where the historical earthquake was probably located. One of the aims of this work was to clarify the seismogenic structure so that the seismic risk in the city could be more accurately evaluated. The area was investigated and analyzed using information from remote sensing and topographic surveys, seismic data from petroleum exploration, shallow seismic profiles, exploratory geological trenches on fault outcrops, and borehole data. The geophysical data did not reveal any evidence of faults cutting through Cretaceous or later strata under the Longkeng scarp, which has been suggested to be structural evidence of the Qian-Gorlos earthquake. The continuous fault surfaces on the back edge of terraces in theHalamaodu area stretch for [3.5 km and were probably formed by tectonic activity. However, results from shallow seismic profiles showed that the faults did not extend downward, with the corresponding deep structure being identified as a gentle kink band. A new reverse fault was found to the west of the two suggested epicenters, which presented as a curvilinear fault extending to the west, and was formed by two groups of NE- and NW-trending faults intersecting the Gudian fault. Three-dimensional seismic and shallow seismic data from petroleum exploration revealed its distinct spatial distribution and showed that the fault may cut through Late Quaternary strata. Exploration boreholes and later geomorphological studies provided further proof of this. Based on these results and analysis,the Gudian fault was confirmed as having been an active fault since the Late Quaternary, with the possibility of earthquakes of magnitude [7 in the future. The QianGorlos earthquake was most probably the result of breakage on one or two sections of this 66-km-long fault. | Jun Shen Bo Shao Xiao-hui Yu Yang Yu Gao Qi Mei Deng Hanwen Zhang | 2016 | Earthquake Science2016，29，2： | 3 |
| 5 | Privacy Protection Algorithm for the Internet of Vehicles Based on Local Differential Privacy and Game Model显示文摘In recent years,with the continuous advancement of the intelligent process of the Internet of Vehicles(IoV),the problem of privacy leakage in IoV has become increasingly prominent.The research on the privacy protection of the IoV has become the focus of the society.This paper analyzes the advantages and disadvantages of the existing location privacy protection system structure and algorithms,proposes a privacy protection system structure based on untrusted data collection server,and designs a vehicle location acquisition algorithm based on a local differential privacy and game model.The algorithm first meshes the road network space.Then,the dynamic game model is introduced into the game user location privacy protection model and the attacker location semantic inference model,thereby minimizing the possibility of exposing the regional semantic privacy of the k-location set while maximizing the availability of the service.On this basis,a statistical method is designed,which satisfies the local differential privacy of k-location sets and obtains unbiased estimation of traffic density in different regions.Finally,this paper verifies the algorithm based on the data set of mobile vehicles in Shanghai.The experimental results show that the algorithm can guarantee the user’s location privacy and location semantic privacy while satisfying the service quality requirements,and provide better privacy protection and service for the users of the IoV. | Wenxi Han Mingzhi Cheng Min Lei Hanwen Xu Yu Yang Lei Qian | 2020 | Computers, Materials & Continua2020，，8： | 3 |
| 6 | Dimensional Gradient Structure of CoSe2@CNTs-MXene Anode Assisted by Ether for High-Capacity,Stable Sodium Storage显示文摘Recently,abundant resources,low-cost sodium-ion batteries are deemed to the new-generation battery in the field of largescale energy storage.Nevertheless,poor active reaction dynamics,dissolution of intermediates and electrolyte matching problems are significant challenges that need to be solved.Herein,dimensional gradient structure of sheet-tube-dots is constructed with CoSe2@CNTs-MXene.Gradient structure is conducive to fast migration of electrons and ions with the association of ether electrolyte.For half-cell,CoSe2@CNTs-MXene exhibits high initial coulomb efficiency(81.7%)and excellent cycling performance(400 mAh g^-1 cycling for 200 times in 2 Ag^−1).Phase transformation pathway from crystalline CoSe2-Na2Se with Co and then amorphous CoSe2 in the discharge/charge process is also explored by in situ X-ray diffraction.Density functional theory study discloses the CoSe2@CNTs-MXene in ether electrolyte system which contributes to stable sodium storage performance owing to the strong adsorption force from hierarchical structure and weak interaction between electrolyte and electrode interface.For full cell,CoSe2@CNTs-MXene//Na3V2(PO4)3/C full battery can also afford a competitively reversible capacity of 280 mAh g^−1 over 50 cycles.Concisely,profiting from dimensional gradient structure and matched electrolyte of CoSe2@CNTs-MXene hold great application potential for stable sodium storage. | Enze Xu Pengcheng Li Junjie Quan Hanwen Zhu Li Wang Yajing Chang Zhenjie Sun Lei Chen Dabin Yu Yang Jiang | 2021 | Nano-Micro Letters2021，13，2： | 1 |

| 10 | Perspectives on exfoliated two-dimensional spintronics显示文摘Magnetic orderings, i.e., the spontaneous alignment of electron spins below a critical temperature, have been playing key roles in modern science and technologies for both the wide applications of magnetic recording for information storage and the vibrant potential of solid state electronic spin devices (also known as spintronics) for logic operations. In the past decades, thanks to the development of thin film technologies, magnetic thin films via sputtering or epitaxial growth have made the spintronic devices possible at the industrial scale. Yet thinner materials at lower costs with more versatile functionalities are highly desirable for advancing future spintronics. Recently, van der Waals magnetic materials, a family of magnets that can in principle be exfoliated down to the monolayer limit, seem to have brought tremendous opportunities: new generation van der Waals spintronic devices can be seamlessly assembled with possible applications such as optoelectronics, flexible electronics, and etc. Moreover, those exfoliated spintronic devices can potentially be compatible with the famed metal-oxide field effect transistor architectures, allowing the harness of spin performances through the knob of an electrostatic field. | Xiaoxi Li Baojuan Dong Xingdan Sun Hanwen Wang Teng Yang Guoqiang Yu Zheng Vitto Han | 2019 | Journal of Semiconductors2019，40，8： | 1 |

| 12 | Wide-beam SAR autofocus based on blind resampling显示文摘Long synthetic aperture time and large instantaneous beam can turn airborne synthetic aperture radar(SAR)autofocus into a wide-beam autofocus problem;i.e.,the motion error is both range-and azimuth-spatial variant.A typical two-step Mo Co method cannot process wide-beam airborne SAR data.Moreover,traditional wide-beam SAR Mo Co algorithms,such as sub-aperture topography and aperturedependent(SATA),precise topography-and aperture-dependent(PTA),and frequency division(FD),are highly dependent on high-precision inertial navigation system/global positioning system(INS/GPS)data and belong to the sub-aperture method,which may result in serious grant-lobe or stitching problems in the image.Alternatively,this article proposes a full-aperture autofocus method for wide-beam SAR based on blind RS.The proposed method does not require INS/GPS data and avoids the problems of traditional subaperture methods,which can significantly improve the overall image quality.The measured data processing results of the wide-beam SAR verify the effectiveness of the proposed algorithm. | Jianlai CHEN Hanwen YU | 2023 | Science China(Information Sciences)2023，66，4： | 1 |

| 15 | MEIC-global-CO_(2):A new global CO_(2)emission inventory with highly-resolved source category and sub-country information显示文摘CO_(2)emission inventory provides fundamental data for climate research and emission mitigation.Currently,most global CO_(2)emission inventories were developed with energy statistics from International Energy Agency(IEA)and were available at country level with limited source categories.Here,as the first step toward a high-resolution and dynamic updated global CO_(2)emission database,we developed a data-driven approach to construct seamless and highly-resolved energy consumption data cubes for 208 countries/territories,797 sub-country administrative divisions in 29 countries,42 fuel types,and 52 sectors,with the fusion of activity data from 24 international statistics and 65 regional/local statistics.Global CO_(2)emissions from fossil fuel combustion and cement production in 1970–2021 were then estimated with highly-resolved source category(1,484 of total)and sub-country information(797 of total).Specifically,73%of global CO_(2)emissions in 2021 were estimated with sub-country information,providing considerably improved spatial resolution for global CO_(2)emission accounting.With the support of detailed information,the dynamics of global CO_(2)emissions across sectors and fuel types were presented,representing the evolution of global economy and progress of climate mitigation.Remarkable differences of sectoral contribution were found across sub-country administrative divisions within a given country,revealing the uneven distribution of energy and economic structure among different regions.Our estimates were generally consistent with existing databases at aggregated level for global total or large emitters,while large discrepancies were observed for middle and small emitters.Our database,named the Multiresolution Emission Inventory model for Climate and air pollution research(MEIC)is publicly available through http://meicmodel.org.cn with highly-resolved information and timely update,which provides an independent carbon emission accounting data source for climate research. | Ruochong XU Dan TONG Qingyang XIAO Xinying QIN Cuihong CHEN Liu YAN Jing CHENG Can CUI Hanwen HU Wenyu LIU Xizhe YAN Huaxuan WANG Xiaodong LIU Guannan GENG Yu LEI Dabo GUAN Kebin HE Qiang ZHANG | 2024 | Science China Earth Sciences2024，67，2： | 0 |
| 16 | Vanillin-based functionalization strategy to construct multifunctional microspheres for treating inflammation and regenerating intervertebral disc显示文摘Intervertebral disc degeneration(IVDD)is one of the main causes of low back pain.Although local delivery strategies using biomaterial carriers have shown potential for IVDD treatment,it remains challenging for intervention against multiple adverse contributors by a single delivery platform.In the present work,we propose a new functionalization strategy using vanillin,a natural molecule with anti-inflammatory and antioxidant properties,to develop multifunctional gelatin methacrylate(GelMA)microspheres for local delivery of transforming growth factorβ3(TGFβ3)toward IVDD treatment.In vitro,functionalized microspheres not only improved the release kinetics of TGFβ3 but also effectively inhibited inflammatory responses and promoted the secretion of extracellular matrix(ECM)in lipopolysaccharide-induced nucleus pulposus(NP)cells.In vivo,functionalized platform plays roles in alleviating inflammation and oxidative stress,preserving the water content of NP and disc height,and maintaining intact structure and biomechanical functions,thereby promoting the regeneration of IVD.High-throughput sequencing suggests that inhibition of the phosphatidylinositol 3-kinase(PI3K)-Akt signaling might be associated with their therapeutic effects.In summary,the vanillin-based functionalization strategy provides a novel and simple way for packaging multiple functions into a single delivery platform and holds promise for tissue regeneration beyond the IVD. | Zhuang Zhu Qifan Yu Hanwen Li Feng Han Qianping Guo Heng Sun He Zhao Zhengdong Tu Zhuang Liu Caihong Zhu Bin Li | 2023 | Bioactive Materials2023，，10： | 0 |
| 17 | High-entropy alloy catalysts:From bulk to nano toward highly efficient carbon and nitrogen catalysis显示文摘High-entropy alloys(HEAs)have attracted widespread attention as both structural and functional materials owing to their huge multielement composition space and unique high-entropy mixing structure.Recently,emerging HEAs,either in nano or highly porous bulk forms,are developed and utilized for various catalytic and clean energy applications with superior activity and remarkable durability.Being catalysts,HEAs possess some unique advantages,including(1)a multielement composition space for the discovery of new catalysts and fine-tuning of surface adsorption(i.e.,activity and selectivity),(2)diverse active sites derived from the random multielement mixing that are especially suitable for multistep catalysis,and(3)a high-entropy stabilized structure that improves the structural durability in harsh catalytic environments.Benefited from these inherent advantages,HEA catalysts have demonstrated superior catalytic performances and are promising for complex carbon(C)and nitrogen(N)cycle reactions featuring multistep reaction pathways and many different intermediates.However,the design,synthesis,characterization,and understanding of HEA catalysts for C-and N-involved reactions are extremely challenging because of both complex high-entropy materials and complex reactions.In this review,we present the recent development of HEA catalysts,particularly on their innovative and extensive syntheses,advanced(in situ)characterizations,and applications in complex C and N looping reactions,aiming to provide a focused view on how to utilize intrinsically complex catalysts for these important and complex reactions.In the end,remaining challenges and future directions are proposed to guide the development and application of HEA catalysts for highly efficient energy storage and chemical conversion toward carbon neutrality. | Lanlan Yu Kaizhu Zeng Chenghang Li Xiaorong Lin Hanwen Liu Wenhui Shi Hua-Jun Qiu Yifei Yuan Yonggang Yao | 2022 | Carbon Energy2022，4，5： | 0 |
| 18 | Time-varying road network design for urban hazmat transportation显示文摘Hazmat transportation in cities faces significant risks that may cause catastrophic losses to humans.From the perspective of the regulator,the main responsibility is to mitigate hazmat transport risk by determining the availability of road networks to hazmat carriers.Based on the time-variant population distribution,the hazmat transport risk was assessed via the total population exposure associated with the resident and variable populations at different times.We propose a risk-minimizing urban hazmat road network design model for multiple types of hazmats,considering time-varying traffic.The model was applied to a realistic case study of hazmat transportation in a densely populated urban area with complex traffic in Shanghai,China. | Jingyi Chen Qiuchen Gu Hanwen Yu Wei Zhou Tijun Fan | 2023 | Journal of Management Science and Engineering2023，8，4： | 0 |
| 19 | Multi-layer composite autoencoders for semi-supervised change detection in heterogeneous remote sensing images显示文摘With the increasing complexity of application scenarios,the fusion of different remote sensing data types has gradually become a trend,which can greatly improve the utilization of massive remote sensing data.While the problem of change detection for heterogeneous remote images can be much more complicated than the traditional change detection for homologous remote sensing images,there are huge differences between heterogeneous images caused by factors such as the light sensitivity and object reflection properties[1,2].So the common methods are meant to align the images from two different domains and then compare the original data in the common domain to highlight the difference[3]. | Jiao SHI Tiancheng WU Hanwen YU A.K.QIN Gwanggil JEON Yu LEI | 2023 | Science China(Information Sciences)2023，66，4： | 0 |
| 20 | Enhanced charge separation by continuous homojunction with spatially separated redox sites for hydrogen evolution显示文摘Photocatalytic hydrogen generation represents a promising strategy for the establishment of a sustainable and environmentally friendly energy reservoir.However,the current solar-to-hydrogen conversion efficiency is not yet sufficient for practical hydrogen production,highlighting the need for further research and development.Here,we report the synthesis of a Sn-doped TiO_(2)continuous homojunction hollow sphere,achieved through controlled calcination time.The incorporation of a gradient doping profile has been demonstrated to generate a gradient in the band edge energy,facilitating carrier orientation migration.Furthermore,the hollow sphere’s outer and inner sides provide spatially separated reaction sites allowing for the separate acceptance of holes and electrons,which enables the rapid utilization of carriers after separation.As a result,the hollow sphere TiO_(2)with gradient Sn doping exhibits a significantly increased hydrogen production rate of 20.1 mmol·g^(−1)·h^(−1).This study offers a compelling and effective approach to the designing and fabricating highly efficient nanostructured photocatalysts for solar energy conversion applications. | Mingyuan Yu Tongyu Wang Chengxi Huang Fang Wu Xuan Liu Hailing Huo Hanwen Jian Zikun Liang Jingjing Ma Erjun Kan Ang Li | 2023 | Nano Research2023，16，10： | 0 |
