1In-situ synthesis of interconnected SWCNT/OMC framework on silicon nanoparticles for high performance lithium-ion batteries显示文摘In spite of silicon has a superior theoretical capacity, the large volume expansion of Si anodes during Li^+ insertion/extraction is the bottle neck that results in fast capacity fading and poor cycling performance. In this paper, we report a silicon, single-walled carbon nanotube, and ordered mesoporous carbon nanocomposite synthesized by an evaporation-induced self-assembly process, in which silicon nanoparticles and single-walled carbon nanotubes were added into the phenolic resol with F-127 for co-condensation. The ordered mesoporous carbon matrix and single-walled carbon nanotubes network could effectively accommodate the volume change of silicon nanoparticles, and the ordered mesoporous structure could also provide efficient channels for the fast transport of Li-ions. As a consequence, this hybrid material exhibits a reversible capacity of 861 mAh g^(-1) after 150 cycles at a current density of 400 mAg^(-1). It achieves significant improvement in the electrochemical performance when compared with the raw materials and Si nanoparticle anodes.Weiwei Li Shimou Chen Jia Yu Daliang Fang Baozeng Ren Suojiang Zhang 2016Green Energy & Environment2016,1,1:7
2Applied Sequence Stratigraphy in Nonmarine Basin of China显示文摘This paper presents a preliminary summary of the applied sequence stratigraphy in nonmarine basins in China. The geological and geophysical data show that the nonmarine sequences mainly resulted from both allocyclic and autocyclic processes where the most important factors were isolated tectonics and climate. However, the environmental factor should have been crucial. The depositional base level served as the sea level in the marine environment, while the water table, lake level and fluvial equilibrium were profiled in a terrigenous environment. This accommodation varied periodically with the base level, resulting in the formation of a series of depositional sequences in terms of genesis and space. Basically, the base level of the inner continent was not affected by the changes in the relative sea level. But there would have been some relations between the changes in the relative sea level and that in the continental base level during eustacy flooding. However, a small time lag existed between the changes in the marine basin and the inner continent basin, The lake basin is smaller than the marine basin, but its velocity of sediment supply is greater than that of the marine basin. Therefore, the number of nonmarine sequences is greater than that of marine ones in the same period. It is important to recognize the system tracts for the study of high-precision or high-resolution sequence stratigraphy, especially to analyze the low-stand systems tract with its depositional system. The sequence boundary is genetically characterized by subaerial exposure, stratigraphic truncation and subaqueous erosion. The deposition analysis of Zhanhua depression reveals 5 sequence architectures: alluvial-fluvial/lacustrine architecture, transitional architecture formed between haline (mesohaline) lake and fresh lake, marine duration-deep lacustrine architecture, half deep lacustrine-ramp architecture and fluvial-alluvial plain architecture. During the major development of the nonmarine basin, the step-faulting breaks controlled the depositional system. Usually, the low-stand complex fan, prograding wedge and high-stand turbidity fan were close to the third stepping break. In the low-stand period, the sediments went around the incised valleys which then were filled with sand bar near the second stepping break. At the first stepping break the sediments were bypassed step by step or the alluvial fan was deposited with forced regressions in the low-stand time. The low-stand wedge may serve as favorable subtle or complex traps at the basin floor fan. The economic effectiveness is measured with the borehole in Bohai Bay basin.Wei Kuisheng Li Daliang Zhang Shoupeng Hao Yunqing Department of Energy and Geology , China University of Geosciences , Beijing 100083 Du Zhenchuan Department of Energy Resomces and Geology , Hebei Technology University , Handan 056038 Zong Guoho 2001Journal of China University of Geosciences2001,12,4:5

4New knowledge of the Upper Triassic in Liupanshan Basin,Ningxia,China显示文摘Based upon the new data of spore pollen, plant and bivalve fossils, the coal bearing strata in the Liupanshan Basin, Ningxia Hui Autonomous Region, Northwest China, which were formerly assigned to the Middle Jurassic Yan’an Formation, are divided into two parts in the present study. The major part is assigned to the Upper Triassic and the overlying part remains in the Jurassic. The new division is of significance to the oil gas exploration of the basin and the interpretation of the sedimentary and tectonic history and the geographic environment of Liupanshan area during the early Mesozoic.Daliang Li Shuxin Dong Shenghui Deng 1998Chinese Science Bulletin1998,43,13:3
5Low-overpotential electrochemical ammonia synthesis using BiOCl-modified 2D titanium carbide MXene显示文摘Electrochemical synthesis of ammonia has the advantages of low energy consumption and promising environmental protection,as compared to the traditional Haber-Bosch process.However,the commercial utilization of this novel system is limited by the low Faradaic efficiency,poor ammonia yield and high overpotential due to the strong NN bond and the dominant competing reaction of hydrogen evolution reaction(HER).Herein,a BiOCl-modified two-dimensional(2D)titanium carbide MXenes nanocomposite(BiOCl@Ti_(3)C_(2)T_(x))is proposed as a promising electrocatalyst for ambient nitrogen(N_(2))reduction reaction with excellent catalytic performance and superior long-term stability at low overpotential.In 0.1 mol/L HCl,this catalyst attains a high Faradic efficiency of 11.98%and a NH_(3)yield of 4.06μg h^(-1)cm^(-2)at-0.10 V(vs.RHE),benefiting from its strong interaction of Bi 6p band with the N 2p orbitals,combined with its large specific surface area and the facile electron transfer.Yu Wang Munkhbayar Batmunkh Hui Mao Hui Li Baohua Jia Shuyao Wu Daliang Liu Ximing Song Ying Sun Tianyi Ma 2022Chinese Chemical Letters2022,33,1:2
6Inside-out dual-doping effects on tubular catalysts:Structural and chemical variation for advanced oxygen reduction performance显示文摘Dual-doping of carbon,especially the combination of nitrogen and a secondary heteroatom,has been demonstrated efficient to optimize the oxygen reduction reaction(ORR)performance.However,the optimum dual-doping is still not clear due to the lack of strong experimental proofs,which rely on a reliable method to prepare carbon materials that can rule out the interference factors and then emphasize only the doping effects.In this work,an inside-out doping method is reported to prepare carbon submicrotubes(CSTs)as a material to study the principles of designing dual-doping catalysts for ORR.The interference factors including the metal impurities and doping gradient in the bulk phase are excluded,and the doping effects including the structural and chemical variation of carbon are studied.P-doping exhibited a higher pore-forming ability to perforate carbon and a lower doping content,but a higher ORR catalytic activity as compared with S-and B-doped N-CSTs,demonstrating the N,P co-doping is more efficient in making carbon-based catalysts for ORR.First-principle calculations reveal that the edge C situated around the oxidized P site nearby a graphitic N atom is the active site that shows the lowest ORR overpotential comparable to Pt-based catalysts.This study suggests that the catalytic activity of dual-heteroatoms-doped carbons not only depends on the intrinsic chemical bonding between heteroatoms and carbon,but also is affected by the structural variation generated by introducing different atoms,which can be extended to the study of other kinds of functionalization of carbon and potential reactions besides ORR.Yang Gao Debin Kong Jiaxu Liang Daliang Han Bin Wang Quan-Hong Yang Linjie Zhi 2022Nano Research2022,15,1:2
7Transformation of Laves phases and its effect on the mechanical properties of TIG welded Mg-Al-Ca-Mn alloys显示文摘The effects of Al content and Ca/Al mass ratio on the microstructure and mechanical properties of tungsten inert gas(TIG)welded Mg-2Ca-x Al-0.5Mn(x=0,1,5)alloy joints were studied in present work.Results showed that increasing Al content was effective in reducing the dendrite spacing at the fusion zone(FZ)edge.The Laves phases in the FZ and the heat-affected zone(HAZ)can be changed from Mg_(2)Ca to(Mg,Al)_(2)Ca with the decrease of Ca/Al ratio,and the(Mg,Al)_(2)Ca could be further transformed to Al_(2)Ca under welding thermal cycle.Furthermore,dynamic dissolution and precipitation of Laves phases and Al_(8)Mn_(5)phases occurred in the HAZ,resulting in a gradient microstructure and hardness peak in this area.The tensile properties of the joints were significantly improved with the increase of Al content,which was mainly due to the modification of Laves phases.Sensen Chai Shiyu Zhong Qingshan Yang Daliang Yu Qingwei Dai Hehe Zhang Limeng Yin Gang Wang Zongxiang Yao 2022Journal of Materials Science & Technology2022,,25:2

9Antenna Selection in Energy Harvesting Relaying Networks Using Q-Learning Algorithm显示文摘In this paper,a novel opportunistic scheduling(OS)scheme with antenna selection(AS)for the energy harvesting(EH)cooperative communication system where the relay can harvest energy from the source transmission is proposed.In this considered scheme,we take into both traditional mathematical analysis and reinforcement learning(RL)scenarios with the power splitting(PS)factor constraint.For the case of traditional mathematical analysis of a fixed-PS factor,we derive an exact closed-form expressions for the ergodic capacity and outage probability in general signal-to-noise ratio(SNR)regime.Then,we combine the optimal PS factor with performance metrics to achieve the optimal transmission performance.Subsequently,based on the optimized PS factor,a RL technique called as Q-learning(QL)algorithm is proposed to derive the optimal antenna selection strategy.To highlight the performance advantage of the proposed QL with training the received SNR at the destination,we also examine the scenario of QL scheme with training channel between the relay and the destination.The results illustrate that,the optimized scheme is always superior to the fixed-PS factor scheme.In addition,a better system parameter setting with QL significantly outperforms the traditional mathematical analysis scheme.Daliang Ouyang Rui Zhao Yuanjian Li Rongxin Guo Yi Wang 2021China Communications2021,18,4:1
