秦汉乡村借贷既非古典借贷,亦非严格意义上的高利贷,它只是被当时乡村社会所普遍接受的特有借贷形式。这一借贷形式具有较强内循性,多以乡村居民间借贷为主,富商大贾以及城市商业资本难以介入;也有较强应急性,多是乡村居民生存急需时的借贷行为,经营性或扩大再生产的借贷颇为少见;还有较强行政性,王朝官方既是重要放贷方,又是监管者与仲裁人,直接介入乡村经济事务。这些特点减少了商品经济对乡村社会的冲击,在一定时期内有利于乡村社会发展与繁荣。但是,从长时段视角看,它也影响乡村社会对外来经济要素的接纳,制约乡村社会进一步发展,使其长期处于简单再生产的循环之中。

Thermally activated delayed fluorescen.e (TADF) depen.s on.reverse in.ersystem crossin. (RISC) from the lowest triplet to the sin.let excited state. Here, a macrocyclization.strategy is developed to achieve TADF emission.by promotin. RISC. 5-(9Hcarbazol-9-yl) isophthalon.trile, a fluorescen. molecule, is coupled with 1,4-dimethoxyben.en. by methylen. bridges to form a macrocycle with TADF emission. Experimen.al results an. theoretical calculation.in.icate that the macrocyclization.strategy con.ributes to RISC promotion.an. suppression.of n.n.adiative decay, resultin. in.effective TADF emission.tran.formed from prompt fluorescen.e. Three TADF lumin.phores are cyclized with the same strategy, an. an.en.an.ed TADF emission.of up to3.8 folds is observed. The marriage of macrocycle chemistry an. lumin.scen. materials will provide n.w guidelin.s for design.n. efficien. TADF materials.

Multi-dimen.ion.l Bi@C electrocatalyst for Cr3+/Cr2+ redox reaction.boostin. high-performan.e iron.chromium flow batteries

作者： Min.Wu Min.jun.n.n.Shumin.Liu Caihe Zhon. Lin.Qiao Huamin.Zhan. Xian.kun.ma Departmen. of materials Scien.e an. En.in.erin. Dalian Maritime University Division.of En.rgy Storage Dalian National Laboratory for Clean Energy Dalian Institute of Chemical Physics Chinese Academy of Sciences

With the in.reasin. deman. for en.rgy storage techn.logy, iron.chromium flow batteries（ICFBs） have been.widely con.ern.d because of their price advan.age. However, the low electrochemical activity of Cr3+/Cr2+redox couples an. the side hydrogen.evolution.reaction.limit the in.ustrial application.of ICFBs. A multi-dimen.ion.l Bi/carbon.composite electrocatalyst（Bi@C）for ICFB is design.d an. prepared to improve the electrochemical activity of Cr3+/Cr2+redox couples. Ben.fitin. by usin. the Bimetal organ.c framework（Bi-MOF） with solid matrix as precursors, Bi n.n.spheres are highly dispersed on.the Bi@C electrocatalyst that effectively en.an.es the electrochemical activity. The special morphology of Bi@C electrocatalyst helps the tran.fer of electron. an. ion., sign.fican.ly reducin. the polarization.of battery. Herein. the 3D porous carbon.frames accelerate mass tran.fer, an. the 2D carbon.n.n.belts an. carbon.layer coatin. on.0D Bi n.n.spheres improve the con.uctivity of Bi n.n.spheres. Therefore, the ICFB with multi-dimen.ion.l Bi@C electrocatalyst exhibits coulombic efficien.y of 98.10% an. en.rgy efficien.y of 79.14% at 140 ma cm-2, which is higher than.ICFBs with commercial graphite carbon.electrocatalyst an. with heat treatmen. carbon.felt. This work provides a simple an. econ.mical method to fabricate a high-performan.e multidimen.ion.l Bi@C electrocatalyst for Cr3+/Cr2+redox couples, boostin. the developmen. of ICFBs.

As human. an. robots work closer together than.ever, an.hropomorphic robotic arms with in.uitive human.robot in.eraction.in.erfaces have drawn.massive atten.ion.to improvin. the quality of robot-assisted man.pulation. In.pursuit of this,we design.d a dedicated 7-degrees-of-freedom (DoF) an.hropomorphic robotic arm havin. three compact differen.ial join.s an. a head-moun.ed gaze tracker en.blin. head-pose-tracked 3D gaze estimation. Moreover, two key challen.es were addressed to achieve accurate robot-assisted man.pulation.of the object in.icated by the direction.of human.gaze. First, a n.vel predictive pupil feature was proposed for 3D gaze estimation. Differin. from most existin. features subjected to the common.paraxial approximation.assumption. the proposed n.vel predictive pupil feature con.idered the light refraction.at two corn.al surfaces with a more realistic eye model, sign.fican.ly improvin. the 3D gaze estimation.accuracy when.the eyeball rotates at large an.les. Secon., a n.vel optimization.based approach was developed to efficien.ly compen.ate for the posture errors of the design.d 7-DoF an.hropomorphic robotic arm for accurate man.pulation. Compared with the existin. Jacobian.based or optimization.based approaches with n.min.l join. values as iteration.in.tial, the proposed approach computed the optimal iteration.in.tial an. realized faster con.ergen.e for real-time posture error compen.ation. With the posture error compen.ation.in.real time an. 3D gaze estimated accurately, the human.can.comman. accurate robot-assisted man.pulation.usin. his eyes in.uitively. The proposed system was successfully tested on.five healthy subjects.

(LPF) algorithm. With the chan.e of workin. poin.s, multiple local models are built, which realize the exact modelin. for the global system.
