| 1 | Ultraselective carbon molecular sieve membrane for hydrogen purification显示文摘Hydrogen is a green clean fuel and chemical feedstock. Its separation and purification from hydrogencontaining mixtures is the key step in the production of hydrogen with high purity(>99.99%). In this work, carbon molecular sieve(CMS) membranes with ultrahigh permselectivity for hydrogen purification were fabricated by high-temperature(700–900 ℃) pyrolysis of polymeric precursor of phenolphthaleinbased cardo poly(arylene ether ketone)(PEK-C). The evolution of the microstructural texture and ultramicroporous structure and gas separation performance of the CMS membrane were characterized via TG-MS, FT-IR, XRD, TEM, CO2 sorption analysis and gas permeation measurements. CMS membranes prepared at 700 ℃ exhibited amorphous turbostratic carbon structures and high H2 permeability of 5260 Barrer with H2/CH4, H2/N2 and H2/CO selectivities of 311, 142, 75, respectively. When carbonized at900 ℃, the CMS membrane with ultrahigh H2/CH4 selectivity of 1859 was derived owing to the formation of the dense and ordered carbon structure. CMS membranes with ultrahigh permselectivity exhibit an attractive application prospect in hydrogen purification. | Ruisong Xu Liu He Lin Li Mengjie Hou Yongzhao Wang Bingsen Zhang Changhai Liang Tonghua Wang | 2020 | Journal of Energy Chemistry2020，29，11： | 8 |
| 2 | Engineering Ruthenium-Based Electrocatalysts for Effective Hydrogen Evolution Reaction显示文摘The investigation of highly effective,durable,and cost-effective electrocatalysts for the hydrogen evolution reaction(HER)is a prerequisite for the upcoming hydrogen energy society.To establish a new hydrogen energy system and gradually replace the traditional fossil-based energy,electrochemical water-splitting is considered the most promising,environmentally friendly,and efficient way to produce pure hydrogen.Compared with the commonly used platinum(Pt)-based catalysts,ruthenium(Ru)is expected to be a good alternative because of its similar hydrogen bonding energy,lower water decomposition barrier,and considerably lower price.Analyzing and revealing the HER mechanisms,as well as identifying a rational design of Ru-based HER catalysts with desirable activity and stability is indispensable.In this review,the research progress on HER electrocatalysts and the relevant describing parameters for HER performance are briefly introduced.Moreover,four major strategies to improve the performance of Ru-based electrocatalysts,including electronic effect modulation,support engineering,structure design,and maximum utilization(single atom)are discussed.Finally,the challenges,solutions and prospects are highlighted to prompt the practical applications of Rubased electrocatalysts for HER. | Yingjie Yang Yanhui Yu Jing Li Qingrong Chen Yanlian Du Peng Rao Ruisong Li Chunman Jia Zhenye Kang Peilin Deng Yijun Shen Xinlong Tian | 2021 | Nano-Micro Letters2021，13，10： | 5 |
| 3 | Influence of t-ZrO_2 addition on mechanical property and electrical conductivity of YSZ electrolyte显示文摘8YSZ material that has high electrical conductivity is widely used as electrolytes for solid oxide fuel cells (SOFCs). But its low strength and low fracture toughness hampered the development of SOFCs. In order to find a best method to improve the capability of YSZ electrolyte, the effects of 3Y-TZP additive on the density, strength, conductivity and microstructure were studied by means of X-ray diffraction and Vicker′s hardness apparatus. The strength and conductivity of YSZ electrolyte doped with different amounts of 3Y-TZP were determined. It is shown that the samples sintered at 1450 ℃ for 2 h are the best in properties. When 3Y-TZP powders are added to the YSZ system, the results demonstrate that strength of the electrolyte increases remarkably, and the fracture toughness is improved. The electrical conductivity is lowered only slightly. The results display that the flexural strength and the fracture toughness of ceramics with 30wt.% TZP reach 300 MPa and 3.7 MPa·m1/2, respectively, and the conductivity at 1000 ℃ reaches 0.11 S·cm-1. | LU Zhixin YU Yanwen GUO Ruisong LI Hailong GUO Qian | 2006 | Rare Metals2006，25，z1： | 1 |

| 10 | Long cycle performance of NC@VN/MnO cathode for AZIBs based on Mn/V relay type collaboration显示文摘Aqueous zinc ion batteries(AZIBs) have received great attention because of their non-toxicity,high safety,low cost,high abundance,and high specific power.However,their specific capacity is still low compared with lithium ion battery,and current academic research interesting has been focused on developing new cathode materials with high specific capacity.In this study,a Mn/V hybrid polymer framework is designed by a simple self-polymerization scheme.During subsequent calcination,ultrafine VN quantum dots and MnO nanoparticles are generated in situ and stably encapsulated inside N-doped carbon(NC) shells to obtain a novel hybrid cathode NC@VN/MnO for AZIBs.According to the density functional theory(DFT) calculation,the hybrids of MnO and VN can generate both interfacial effects and built-in electric fields that significantly accelerate ion and electron transport by tuning the intrinsic electronic structure,thus enhancing electrochemical performance.A synergistic strategy of composition and structural design allows the rechargeable AZIBs to achieve low-cost and excellent long-cycle performance based on a relay type collaboration at different cycling stages.Consequently,the NC@VN/MnO cathode has output a capacity of 108.3 mA h g^(-1)after 12,000 cycles at 10 A g^(-1).These results clearly and fully demonstrate the advantages of the hybrid cathode NC@VN/MnO. | Tingting Li Ruisong Guo Yang Li Leichao Meng Xiaohong Sun Fuyun Li Xinqi Zhao Zhongkai Xu Jianhong Peng Lingyun An | 2023 | Journal of Energy Chemistry2023，，8： | 0 |
| 11 | Financial performance evaluation and forecasting of enterprises by the combination of PCA and CNN deep learning显示文摘1 Introduction Financial evaluation focuses on pursuing sustainable financial development under the“New Normal”of China’s economy.It is of great practical significance to explore innovative methods based on established financial evaluation indexes and systems[1,2].The joint strategy of PCA methods and Deep Learning models seems to have a scientific basis and a good fusion mechanism in earlier studies[3-5].The innovation of our research is to combine evaluation method,unsupervised learning,with supervised learning.Based on the PCA method,the selected data is dimensionally reduced and comprehensively scored,then the unsupervised learning K-means clustering method is used to divide the sample into five evaluation levels according to the performance score.Finally,combined with the Convolutional Neural Network(CNN)framework,the company’s financial performance can be profiled and predicted.On one hand,the theoretical significance of this study is to combine the traditional PCA method with the Deep Learning method to predict the performance level for the performance portrait of enterprises. | Ruisong LI Hongjiu LIU Yanrong HU | 2023 | Frontiers of Computer Science2023，17，6： | 0 |
| 12 | Simultaneous realization of high sulfur utilization and lithium dendrite-free via dual-effect kinetic regulation strategy toward lithium-sulfur batteries显示文摘With the high theoretical specific capacity and energy density,lithium-sulfur batteries(LSBs)have been intensively studied as promising candidates for energy storage devices.However,LSBs are largely hindered by inferior sulfur utilization and uncontrollable dendritic growth.Herein,a hierarchical functionalization strategy of stepwise catalytic-adsorption-conversion for sulfur species via the synergetic of the efficiently catalytic host cathode and light multifunctional interlayer has been proposed to concurrently address the issues arising on the dual sides of the LSBs.The multi-layer SnS_(2) micro-flowers embedded into the natural three-dimensional(3D)interconnected carbonized bacterial cellulose(CBC)nanofibers are fabricated as the sulfur host that provides numerous catalytic sites for the rapid catalytic conversion of sulfur species.Moreover,the distinctive CBC-based SnO_(2)-SnS_(2) heterostructure network accompanied high conductive carbon nanofibers as the multifunctional interlayer promotes the rapid anchoringdiffusion-conversion of lithium polysulfides,Li^(+)flux redistribution,and uniform Li deposition.LSBs equipped with our strategy exhibit a high reversible capacity of 1361.5 m A h g^(-1)at 0.2 C and superior cycling stability with an ultra-low capacity fading of 0.031%per cycle in 1000 cycles at 1.5 C and 0.046%at 3 C.A favorable specific capacity of 859.5 m A h g^(-1)at 0.3 C is achieved with a high sulfur mass loading of 5.2 mg cm^(-2),highlighting the potential of practical application.The rational design in this work can provide a feasible solution for high-performance LSBs and promote the development of advanced energy storage devices. | Xinqi Zhao Xiaohong Sun Ruisong Guo Song Wang Fuyun Li Tingting Li Wen Zhang Chunming Zheng Lingyun An Leichao Meng Xudong Hu | 2023 | Journal of Energy Chemistry2023，，6： | 0 |
| 13 | General approach for atomically dispersed precious metal catalysts toward hydrogen reaction显示文摘As a carbon-free energy carrier,hydrogen has become the pivot for future clean energy,while efficient hydrogen production and combustion still require precious metal-based catalysts.Single-atom catalysts(SACs)with high atomic utilization open up a desirable perspective for the scale applications of precious metals,but the general and facile preparation of various precious metal-based SACs remains challenging.Herein,a general movable printing method has been developed to synthesize various precious metal-based SACs,such as Pd,Pt,Rh,Ir,and Ru,and the features of highly dispersed single atoms with nitrogen coordination have been identified by comprehensive characterizations.More importantly,the synthesized Pt-and Ru-based SACs exhibit much higher activities than their corresponding nanoparticle counterparts for hydrogen oxidation reaction and hydrogen evolution reaction(HER).In addition,the Pd-based SAC delivers an excellent activity for photocatalytic hydrogen evolution.Especially for the superior mass activity of Ru-based SACs toward HER,density functional theory calculations confirmed that the adsorption of the hydrogen atom has a significant effect on the spin state and electronic structure of the catalysts. | Ruisong Li Daoxiong Wu Peng Rao Peilin Deng Jing Li Junming Luo Wei Huang Qi Chen Zhenye Kang Yijun Shen Xinlong Tian | 2023 | Carbon Energy2023，5，7： | 0 |
| 14 | Analytical model of cutting force in axial ultrasonic vibration-assisted milling in-situ TiB_(2)/7050Al PRMMCs显示文摘Ultrasonic vibration-assisted milling has been widely applied in machining the difficultto-cut materials owing to the remarkable improvements in reducing the cutting force.However,analytical models to reveal the mechanism and predict the cutting force of ultrasonic vibrationassisted milling metal matrix composites are still needed to be developed.In this paper,an analytical model of cutting force was established for ultrasonic vibration-assisted milling in-situ TiB_(2)/7050 Al metal matrix composites.During modeling,change of motion of the cutting tool,contact of toolchip-workpiece and acceleration of the chip caused by ultrasonic vibration was considered based on equivalent oblique cutting model.Meanwhile,material properties,tool geometry,cutting parameters and vibration parameters were taken into consideration.Furthermore,the developed analytical force model was validated with and without ultrasonic vibration milling experiments on in-situ TiB_(2)/7050 Al metal matrix composites.The predicted cutting forces show to be consistent well with the measured cutting forces.Besides,the relative error of instantaneous maximum forces between the predicted and measured data is from 0.4%to 15.1%.The analytical model is significant for cutting force prediction not only in ultrasonic-vibration assisted milling but also in conventional milling in-situ TiB_(2)/7050 Al metal matrix composites,which was proved with general applicability. | Xiaofen LIU Wenhu WANG Ruisong JIANG Yifeng XIONG Kunyang LIN Junchen LI Chenwei SHAN | 2021 | Chinese Journal of Aeronautics2021，34，4： | 0 |
| 15 | Se-sensitized NIR hot band absorption photosensitizer for anti-Stokes excitation deep photodynamic therapy显示文摘Conventional anti-Stokes materials-involved deep photodynamic therapy(dPDT)requires much high-intensity irradiance due to low photosensitization efficiency.Herein,we proposed a'booster effector'approach to construct highly efficient hot band absorption phototherapeutics for low/biosafety power anti-Stokes light-triggered d PDT.Se,as'booster effector',was introduced into hot band absorption luminophores(HBAs),which not only significantly facilitated intersystem crossing,but also simultaneously enhanced hot band excitation efficiency atν808,as a result successfully enabling excellent photogenerated singlet oxygen capability of HBAs under ultra-low power anti-Stokes excitation(10 mW cm^(-2)in vitro).As far as we know,such low laser power-initiated photosensitization activity has never been reported in the existing anti-Stokes material systems.Importantly,FUC-Se ME can self-assemble into uniform nanospheres in water,greatly boosting cellular uptake(>25-fold larger than FUC-Se),and achieve superior cancer-killing effect(808 nm,10 mW cm^(-2),5 min,the half-maximal inhibitory concentration IC50=1.36μM).After further PEGylation with folate-attached polymer,the resultant FUC-Se ME@FA can effectively enrich at the tumor(signal-to-background ratio,10).Under safety irradiation(330 mW cm^(-2)),FUC-Se ME@FA effectively inhibits deep-seated tumor progression(the tumor growth inhibition rate,84%).This work provides a successful paradigm,possibly being more clinically beneficial than conventional anti-Stokes materials. | Dandan Ma Hui Bian Saran Long Panwang Zhou Ruisong Tian Yingnan Wu Haoying Ge Mingle Li Jianjun Du Jiangli Fan Yukui Zhang Xiaojun Peng | 2022 | Science China Chemistry2022，65，3： | 0 |
