Single-ion conductors based on covalent organic frameworks (COFs) have garnered attention as a potential alternative to currently prevalent inorganic ion conductors owing to their structural uniqueness and chemical versatility.

Here, we present a class of solvent-free COF single-ion conductors (li-COF@P) based on weak ion-dipole interaction as opposed to traditional strong ion-ion interaction. The ion (li+ from the COF)-dipole (oxygen from poly(ethylene glycol) diacrylate embedded in the COF pores) interaction in the li-COF@P promotes ion dissociation and li+ migration via directional ionic channels. Driven by this single-ion transport behavior, the li-COF@P enables reversible li plating/stripping on li-metal electrodes and stable cycling performance (88.3% after 2000 cycles) in organic batteries (li metal anode||5,5'-dimethyl-2,2'-bis-p-benzoquinone (Me2BBQ) cathode) under ambient operating conditions, highlighting the electrochemical viability of the li-COF@P for all-solid-state organic batteries.

数字经济发展对收入差距的影响事关包容性增长的整体实现。使用2010~2020年个体与省级层面相结合的面板数据,采用双向固定效应模型检验数字经济发展水平对低中技能劳动力与高技能劳动力间收入差距的作用和机制。研究表明:数字经济发展水平的提高拉大了低中技能劳动力与高技能劳动力间的收入差距,且产业智能化在这一过程中发挥了中介作用。异质性分析表明:在中国东部地区、非农业户口劳动力群体中,数字经济对收入差距的拉大作用均得以增强;在中国中西部地区、农业户口劳动力群体中,数字经济对收入差距的作用分别为缩小和无显著影响。同时,数字经济发展前期对低中技能劳动力与高技能劳动力间的收入差距无明显作用,但后期扩大收入差距的作用逐渐显现。研究结论拓展了数字经济与收入差距相关的研究,为政府制定相应政策提供了可操作性建议,有助于为后期数字经济推动包容性增长蓄力。

RELAXED CONDITIONS FOR CONSENSUS IN MULTI-AGENT COORDINATION

引用

Journal of Systems Science & Complexity 2008年第3期21卷 347-361页

作者： Qin li zhongping JIANG Department of Electrical and Computer Engineering Polytechnic University Six Metrotech Center Brooklyn NY 11201 USA

This paper proposes relaxed sufficient conditions for the consensus of multi-agent systems by the averaging protocols with time-varying system topology. Bidirectional information exchange between neighboring agents is considered and both the discrete-time and continuous-time consensus protocols are studied. It is shown that the consensus is reached if there exists an unbounded time sequence such that two agents who own the maximum and minimum states at each time instant in the sequence will be jointly connected at some future time. Further, this result is applied to the original nonlinear Vicsek model, and a sufficient condition for the heading consensus of the group with restricted initial conditions is obtained.

General Trends in Electronic Structure, Stability, Chemical Bonding and Mechanical Properties of Ultrahigh Temperature Ceramics TMB_2(TM=transition metal)

引用

Journal of Materials Science & Technology 2015年第3期31卷 285-294页

作者： Yanchun Zhou Huimin Xiang Zhihai Feng zhongping li Science and Technology on Advance Functional Composite Laboratory Aerospace Research Institute of Materials & Processing Technology

The electronic structure, stability, chemical bonding and mechanical properties of 3d, 4d and 5d transition metal diboride TMB2 were investigated using first-principles calculations based on density functional theory. All the primary chemical bonds, i.e., metallic, ionic and covalent have contributions to the bonding of TMB2. The number of valence electrons of transition metals or the valence electron concentration(VEC) of TMB2 has strong effects on the lattice parameters, stability and mechanical properties of TMB2. Both lattice constants a and c decrease with VEC, but c decreases faster than a, which is attributed to the enhanced TM de B p(sp2) bonding. Bulk modulus B of TMB2 increases continuously with VEC due to the enhanced TM de B p(sp2) and TM dd bonding. Shear modulus G increases with VEC,reaching a maximum at VEC=3.33, and then decreases with further increase of VEC. YB2 and Mn B2 have low Young’s modulus and are predicted to have good thermal shock resistance. According to Pugh’s criterion(G/B < 0.571), Mn B2, Mo B2 and WB2are predicted as ductile or damage tolerant ultrahigh temperature ceramics(UHTCs).
