| 1 | Modifying the Power and Performance of 2-Dimensional MoS_(2)Field Effect Transistors显示文摘Over the past 60 years,the semiconductor industry has been the core driver for the development of information technology,contributing to the birth of integrated circuits,Internet,artificial intelligence,and Internet of Things.Semiconductor technology has been evolving in structure and material with co-optimization of performance–power–area–cost until the state-of-the-art sub-5-nm node.Two-dimensional(2D)semiconductors are recognized by the industry and academia as a hopeful solution to break through the quantum confinement for the future technology nodes.In the recent 10 years,the key issues on 2D semiconductors regarding material,processing,and integration have been overcome in sequence,making 2D semiconductors already on the verge of application.In this paper,the evolution of transistors is reviewed by outlining the potential of 2D semiconductors as a technological option beyond the scaled metal oxide semiconductor field-effect transistors.We mainly focus on the optimization strategies of mobility(μ),equivalent oxide thickness(EOT),and contact resistance(RC),which enables high ON current(Ion)with reduced driving voltage(Vdd).Finally,we prospect the semiconductor technology roadmap by summarizing the technological development of 2D semiconductors over the past decade. | Fulin Zhuo Jie Wu Binhong Li Moyang Li Chee Leong Tan Zhongzhong Luo Huabin Sun Yong Xu Zhihao Yu | 2023 | Research2023，，3： | 2 |
| 2 | A facile self-catalyzed CVD method to synthesize Fe3C/N-doped carbon nanofibers as lithium storage anode with improved rate capability and cyclability显示文摘Uniform Fe3 C/N-doped carbon nanofibers were successfully synthesized through a facile self-catalyzed CVD method by using acetylene as carbon source and Fe3O4 as iron source and autocatalytic template for the reaction under moderate preparation conditions. The experimental and theoretical calculation results demonstrate that Fe3 C can improve the lithium storage performance of carbon nanofibers. Besides, the addition of PPy can not only control the growth rate of carbon fibers but also help to form uniform carbon fibers. As a result, the obtained Fe3 C/N-doped carbon nanofiber composites display favorable electrochemical performance as an anode for lithium-ion batteries, which including satisfactory rate performance of 402 m A h g-1 under 1.2 Ag-1, and good cycling stability of 502.3 m A h g-1 under 200 m Ag-1 over 400 cycles. The introduction of Fe3 C species and the uniform carbon fiber morphology are responsible for the long-cycling and high rate performance of materials. | Liang Chen Zhi Li Gangyong Li Minjie Zhou Binhong He Jie Ouyang Wenyuan Xu Wei Wang Zhaohui Hou | 2020 | Journal of Materials Science & Technology2020，44，9： | 2 |
| 3 | Highly sensitive fluorescence detection of chloride ion in aqueous solution with Ag-modified porous g-C_(3)N_(4) nanosheets显示文摘The porous g-C_(3)N_(4)(PCN)nanosheets are successfully synthesized and further modified with nano-sized Ag by a simple wet-chemical process.Intere stingly,the Ag-modified porous g-C_(3)N_(4)(Ag-PCN)nanosheets exhibit competitive fluorescence detection performance of chloride ion(Cl)in aqueous solutio n.Under the optimized conditions,the concentration of Cl could be quantitative analyzed with the Ag-PCN in a wide detection range from 0.5 mmol/L to 0.1 mol/L,with a low detection limitation of 0.06 mmol/L.It is confirmed that the fluorescence of PCN could be effectively decayed by the photoinduced charge transfer via the adsorbed Cl for trapping holes,mainly by means of the time-resolved fluorescence and surface photo voltage spectra.The porous structure and modified Ag promote the adsorption of Cl on resulting Ag-PCN,leading to excellent fluorescence detection for Cl.This work provides a feasible route to develop a fluorescence detection of Cl with g-C_(3)N_(4) nanosheets in environment water. | Zishu Zhang Ying Gao Peng Li Binhong Qu Zhiyuan Mu Yang Liu Yang Qu Degui Kong Qing Chang Liqiang Jing | 2020 | Chinese Chemical Letters2020，31，10： | 2 |
| 4 | Revealing the critical effect of solid electrolyte interphase on the deposition and detriment of Co(Ⅱ) ions to graphite anode显示文摘'Dissolution,migration,and deposition'of transition metal ions (TMIs) result in capacity degradation of lithium-ion batteries (LIBs).Understanding such detrimental mechanism of TMIs is critical to the development of LIBs with long cycle life.In most previous works,TMIs were directly introduced into the electrolyte to investigate such a detrimental mechanism.In these cases,the TMIs are deposited directly on the fresh anode surface.However,in the practical battery system,the TMIs are deposited on the anode covered with solid electrolyte interphase (SEI) film.Whether the pre-presence of SEI film on anode surface influences the deposition and detriment of TMIs is unclear.In this work,the deposition of Co element on graphite anode with and without SEI film were systematically studied.The results clearly show that,in comparison with that of fresh graphite (SEI-free),the presence of SEI film aggravates the deposition of Co ions due to the Li^(+)–Co^(2+) ion exchange between the SEI and Co^(2+)-containing electrolyte without the driving of the electric field,leading to faster capacity fading of graphite anode.Therefore,how to regulate electrolytes and film-forming additives to design the components of SEI and prevent its exchange with TMIs,is a crucial way to inhibit the deposition and detriment of TMIs on graphite anode. | Qiming Xie Jiawei Chen Lidan Xing Xianggui Zhou Zekai Ma Binhong Wu Yilong Lin Hebing Zhou Weishan Li | 2022 | Journal of Energy Chemistry2022，31，6： | 2 |
| 5 | Single-event burnout hardening of planar power MOSFET with partially widened trench source显示文摘We present a single-event burnout(SEB) hardened planar power MOSFET with partially widened trench sources by three-dimensional(3 D) numerical simulation. The advantage of the proposed structure is that the work of the parasitic bipolar transistor inherited in the power MOSFET is suppressed effectively due to the elimination of the most sensitive region(P-well region below the N+ source). The simulation result shows that the proposed structure can enhance the SEB survivability significantly. The critical value of linear energy transfer(LET),which indicates the maximum deposited energy on the device without SEB behavior, increases from 0.06 to0.7 p C/μm. The SEB threshold voltage increases to 120 V, which is 80% of the rated breakdown voltage. Meanwhile, the main parameter characteristics of the proposed structure remain similar with those of the conventional planar structure. Therefore, this structure offers a potential optimization path to planar power MOSFET with high SEB survivability for space and atmospheric applications. | Jiang Lu Hainan Liu Xiaowu Cai Jiajun Luo Bo Li Binhong Li Lixin Wang Zhengsheng Han | 2018 | Journal of Semiconductors2018，39，3： | 1 |

| 10 | CoS_(2)/N,S co-doped mesoporous carbon with 3D micro-nano crosslinked structure as efficient bifunctional oxygen electrocatalysts for zinc-air batteries显示文摘This work describes a bifunctional oxygen catalyst made of cobalt disulfide encapsulated in N,S codoped mesoporous carbon with a novel three-dimensional micro-nano crosslinking structure.The proposed composite materials exhibit promising oxygen electrocatalytic activity and stability.The composite assembled rechargeable zinc-air battery can achieve a high power density of 208.9 m W/cm^(2),and can be stably cycled for more than 160 h.Additionally,the all-solid zinc-air battery assembled with the electrocatalyst also performs admirably.The micro-nano crosslinking and high porosity structure,as well as the large number of active sites generated by the synergy of N,S doping and the close interface between carbon matrix and CoS_(2),contribute to the composite's exceptional electrochemical performance.This study's rational strategy lays the path for the development of other high-performance bifunctional electrocatalysts. | Wei Wang Liqin Li Jie Ouyang Jialin Gong Jie Tian Liang Chen Junlin Huang Binhong He Zhaohui Hou | 2023 | Chinese Chemical Letters2023，34，5： | 0 |
| 11 | Should Low-Frequency-High-Consumption Enterprises Add Online-to-Offline Platforms?An Empirical Study Using the VAR Model显示文摘This study investigates the impact of online-to-offline(O2O)platforms,such as Ele.me and Meituan,on offline sales in low-frequency-high-consumption industries,specifically a mid-to-highend liquor distribution chain.Using data from 77 offline stores in Beijing collected during 2019-2022,the study employs a VAR model to analyze the relationship between offline sales and the use of O2O platforms.The results reveal a long-term equilibrium between the two,with most indicators showing a positive impact of O2O platforms on offline sales.The research provides valuable insights for lowfrequency-high-consumption enterprises in making multi-channel decisions and quantifies the impact of O2O platforms on offline sales. | Wei LI Ying LIU Haizhen YANG Sha ZHANG Binhong XU | 2024 | Journal of Systems Science and Information2024，12，1： | 0 |
| 12 | In-situ self-templated preparation of porous core-shell Fe_(1-x)S@N,S co-doped carbon architecture for highly efficient oxygen reduction reaction显示文摘Transition metal compound(TMC)/carbon hybrids,as prospering electrocatalyst,have attracted great attention in the field of oxygen reduction reaction(ORR).Their morphology,structure and composition often play a crucial role in determining the ORR performance.In this work,we for the first time report the successful fabrication of porous core-shell Fe_(1-x)S@N,S co-doped carbon(Fe_(1-x)S@NSC-t,t represents etching time)by a novel in-situ self-template induced strategy using Fe3O4 nanospheres and pyrrole as sacrificial self-template.The post-polymerization of pyrrole can be accomplished by the Fe^(3+)released through the etching of Fe_(3)O_(4) by HCl acid.Thus,the etching time has a significant effect on the morphology,structure,composition a nd ORR performance of Fe_(1-x)S@NSC-t.Based on the cha racterizations,we find Fe_(1-x)S@NSC-24 can realize effective and balanced combination of Fe_(1-x)S and NSC,possessing porous core-shell architecture,optimized structure defect,specific surface area and doped heteroatoms configurations(especially for pyridinic N,graphitic N and Fe-N structure).These features thus lead to outstanding catalytic activity and cycling stability towards ORR.Our work provides a good guidance on the design of TMC/carbon-based electrodes with unique stable morphology and optimized structure and composition. | Zhi Li Wei Wang Minjie Zhou Binhong He Wenqing Ren Liang Chen Wenyuan Xu Zhaohui Hou Yangyang Chen | 2021 | Journal of Energy Chemistry2021，30，3： | 0 |
| 13 | Rotating Surfaces Promote the Shedding of Droplets显示文摘Achieving rapid shedding of droplets from solid surfaces has received substantial attention because of its diverse applications.Previous studies have focused on minimizing contact times of liquid droplets interacting with stationary surfaces,yet little consideration has been given to that of moving surfaces.Here,we report a different scenario:A water droplet rapidly detaches from micro/nanotextured rotating surfaces in an intriguing doughnut shape,contributing to about 40%contact time reduction compared with that on stationary surfaces.The doughnut-shaped bouncing droplet fragments into satellites and spontaneously scatters,thus avoiding further collision with the substrate.In particular,the contact time is highly dependent on impact velocities of droplets,beyond previous descriptions of classical inertialcapillary scaling law.Our results not only deepen the fundamental understanding of droplet dynamics on moving surfaces but also suggest a synergistic mechanism to actively regulate the contact time by coupling the kinematics of droplet impingement and surface rotation. | Ran Tao Wei Fang Jun Wu Binhong Dou Wanghuai Xu Zhanying Zheng Bing Li Zuankai Wang Xiqiao Feng Chonglei Hao | 2023 | Research2023，，1： | 0 |
| 14 | Manufacturing N,O-carboxymethyl chitosan-reduced graphene oxide under freeze-dying for performance improvement of Li-S battery显示文摘Lithium-sulfur(Li-S) batteries can provide far higher energy density than currently commercialized lithium ion batteries, but challenges remain before it they are used in practice.One of the challenges is the shuttle effect that originates from soluble intermediates, like lithium polysulfides. To address this issue, we report a novel laminar composite, N,O-carboxymethyl chitosan-reduced graphene oxide(CC-rGO), which is manufactured via the self-assembly of CC onto GO and subsequent reduction of GO under an extreme condition of 1 Pa and-50°C. The synthesized laminar CC-rGO composite is mixed with acetylene black(AB) and coated on a commercial polypropylene(PP) membrane, resulting in a separator(CC-rGO/AB/PP) that can not only completely suppress the polysulfides penetration, but also can accelerate the lithium ion transportation, providing a Li-S battery with excellent cyclic stability and rate capability. As confirmed by theoretic simulations, this unique feature of CC-rGO is attributed to its strong repulsive interaction to polysulfide anions and its benefit for fast lithium ion transportation through the paths paved by the heteroatoms in CC. | Zhibin Jiang Lujie Jin Xiying Jian Jinxia Huang Hongshuai Wang Binhong Wu Kang Wang Ling Chen Youyong Li Xiang Liu Weishan Li | 2023 | International Journal of Extreme Manufacturing2023，5，1： | 0 |
