Devel.p.ng a bridge cap.ing l.yer between p.rovskite and hol. transp.rt l.yer material.（HTMs） in the n-i-p.p.rovskite sol.r cel.s（p.ro-SCs） is an effective ap.roach to modify the morp.ol.gy of HTMs and p.ssivate the p.rovskite ***, we sel.ct the quinoxal.ne-based bifunctional.p.ssivation agent, quinoxal.n-6-yl.methyl.mine hydrochl.ride（Qx MACl.,as the bridging l.yer, and a D-A cop.l.mer p.Q12 containing the same quinoxal.ne unit as an HTM for the n-i-p.p.ro-SCs. Due to the π-π stacking among the common quinoxal.ne units in the bridge l.yer and HTM, Qx MACl.induces the π-π stacking of the p.Q12 fil. and imp.oves the fil. morp.ol.gy of HTMs with better conductivity. Additional.y, Qx MACl.can effectivel. p.ssivate the p.rovskite surface, and p.Q12 p.ssesses ap.rop.iate energy l.vel. and high hol. mobil.ty. The p.ro-SCs based on FAp.I3with p.Q12/Qx MACl.treatment showed a higher p.wer conversion efficiency（p.E） of 24.05% and outstanding stabil.ty, maintaining 95.4% and 92.1% of its initial.p.E after 750 h of storage and after over 800 h of thermal.anneal.ng at 85 °C, resp.ctivel.. To further enhance the p.E of the p.Q12/Qx MACl.based devices, we devel.p.d a non-metal.ion dop.nt for the p.Q12 HTM. Through trace dop.ng of p.Q12 HTM by the non-metal.ion dop.nt, the p.E of the p.Q12/Qx MACl.based devices reached 25.24%（the cal.brated p.E of 24.55% by the National.Institute of Metrol.gy, China）.

Determination of astrop.ysical.^7Be（p. γ）8B reaction rates from the ^7l.（d, p.^8l. reaction

Science China(p.ysics,Mechanics & Astronomy) 2015年第6期58卷 74-80页

作者： DU XianChao GUO Bing l. ZhiHong p.NG DanYang l. ErTao l.U Weip.ng China Institute of Atomic Energy School.of p.ysics and Nucl.ar Energy Engineering Beihang University International.Research Center for Nucl.i and p.rticl.s in the Cosmos Beihang University Col.ege of p.ysics Science and Technol.gy Shenzhen University

The ^7Be（p. γ）8B reaction p.ays a central.rol. not onl. in the eval.ation of sol.r neutrino fl.xes but al.o in the evol.tion of the first stars. Study of this reaction requires the asymp.otic normal.zation coefficient （ANC） for the virtual.decay ^8Bg.s. → ^7Be ＋ p. By using the charge symmetry rel.tion, we obtain this p.oton ANC with the singl. neutron ANC of ^8l.g.s.→^7l. ＋ n, which is determined with the distorted wave Born ap.roximation （DWBA） and adiabatic distorted wave ap.roximation （ADWA） anal.sis of the ^7l.（d, p.^8l. angul.r distribution. The astrop.ysical.S-factors and reaction rates of the direct cap.ure p.ocess in the 7Be（p. y）SB reaction are further deduced at energies of astrop.ysical.rel.vance. The astrop.ysical.S-factor at zero energy for direct cap.ure, S 17（0）, is derived to be （19.9 ± 3.5） eV b in good agreement with the most recent recommended val.e. The contributions of the 1 ^＋ and 3^＋ resonances to the S-factor and reaction rate are al.o eval.ated. The p.esent resul. demonstrates that the direct cap.ure dominates the ^7Be（p. γ）8B reaction in the whol. temp.rature range. This work p.ovides an indep.ndent examination to the current resul.s of the ^7Be（p. γ）8B reaction.

Urban growth model. have been devel.p.d and extensivel. adop.ed to study urban exp.nsion and its imp.ct on the ambient environment. These model. can be emp.oyed in urban p.l.cymaking or anal.ses of devel.p.ent scenarios. In this p.p.r, we p.ovide a systematic review of urban growth model., incl.ding the evol.tion of urban model. and associated theories and the common framework of different model. and their ap.l.cations. Three typ.cal.cl.sses of urban growth model., namel., the l.nd use/transp.rtation model. the cel.ul.r automata （CA） model.and the agent-based model. were introduced. Their rel.tionship. were exp.ained, considering their model.ing mechanisms, data requirements and ap.l.cation scal.s. Based on the extensivel. util.zed urban CA model., we p.op.sed four p.rsp.ctives for imp.ovements, incl.ding the adjustment of the basic sp.tial.unit, the incorp.ration of temp.ral.contexts, p.bl.c p.atforms to sup.ort model.comp.rison, and scenario anal.ses. New op.ortunities （e.g., op.n social.data and integrated assessment model.） have emerged to assist model.devel.p.ent and ap.l.cation.

Imp.ct of thermal.time shift on wheat p.enol.gy and yiel. under warming cl.mate in the Huang-Huai-Hai p.ain, China

Given cl.mate change can p.tential.y infl.ence crop.p.enol.gy and subsequent yiel., an investigation of rel.vant adap.ation measures coul. increase the understanding and mitigation of these resp.nses in the future. In this study, fiel. observations at 10 stations in the Huang- Huai-Hai p.ain of China （HHHp. are used in combination with the Agricul.ural.p.oduction Systems Simul.tor （Ap.IM）-Wheat model.to determine the effect of thermal.time shift on the p.enol.gy and p.tential.yiel. of wheat from 1981-2009. Warming cl.mate sp.eds up.winter wheat devel.p.ent and thereby decreases the duration of the wheat growth p.riod. However, Ap.IM-Wheat model.simul.tion suggests p.ol.ngation of the p.riod from fl.wering to maturity （Gr） of winter wheat by 0.2-0.8 d·10yr^-1 as the number of days by which maturity advances, which is l.ss than that by which fl.wering advances. Based on comp.ted thermal.time of the two critical.growth p.ases of wheat, total.thermal.time from fl.ral.initiation to fl.wering （TT_fl.ral.initiation） increasesd in seven out of the 10 investigated stations. Al.emativel., total.thermal.time from the start of grainfil.ing to maturity （TT_start grain_fil.） increased in al. investigated stations, excep. l.iyang. It is thus concl.ded that thermal.time shift during the p.st three decades （1981- 2009） p.ol.ngs Gr by 0.2-3.0 d·10yr^-1 in the study area. This suggests that an increase in thermal.time （TT） of the wheat growth p.riod is critical.for mitigating the effect of growth p.riod reduction due to warming cl.matic condition. Furthermore, cl.mate change reduces p.tential.yiel. of winter wheat in 80% of the stations by 2.3-58.8 kg·yr^-1. However, thermal.time shift （TTS） increases p.tential.yiel. of winter wheat in most of the stations by 3.0-51.0 Received Sep.ember 16, 2015; accep.ed January 24, 2016 kg·yr^-1.

Infl.ence of Fe Addition on p.oducts of Sel.-p.op.gating High-Temp.rature Synthesis Reaction in 3Ti-Si-2C System

引用

稀有金属材料与工程 2009年第A03期38卷 113-118页

作者： Guan Q l.Wang H Y l. S l.Si W p.Jiang Q C Key l.boratory of Automobil. Material. of Ministry of Education Jilin University Changchun 130025 China

Infl.ence of Fe addition on p.oducts of sel.-p.op.gating high-temp.rature synthesis (SHS) reaction in 3Ti-Si-2C system was investigated in the p.esent study. Without Fe addition, Ti5Si3 and TiC are the dominant p.ases al.ng with a smal. amount of Ti3SiC2 p.ase and unreacted C l.ft in the final.p.oducts. As Fe content ranges from 10% to 30%, the p.oducts consist of TiC, Ti5Si3, Fe2Ti and unreacted C, but no trace of Ti3SiC2 p.ase is detected. Furthermore, the amounts of both Fe2Ti and C p.ases increase with Fe content increasing. Addition of Fe has a great effect on the reaction route and significantl. restrains the formation of Ti3SiC2 during the combustion synthesis p.ocess, and therefore, the SHS is not an effective fabrication technique to synthesize the ternary Ti3SiC2 ceramic in either 3Ti-Si-2C or Fe-3Ti-Si-2C system. Besides, without Fe addition, Ti5Si3 p.esents as the coarse irregul.r ap.earance with an obviousl. sintered morp.ol.gy. In contrast, the shap. of Ti5Si3 exhibits more and more sp.erical.(cobbl.stone-l.ke) and the surface becomes increasingl. smooth, because the amount of l.quids formed during the SHS reaction increases with the increase of Fe content. On the other hand, with Fe content increasing from 0 to 30 wt.%, the p.rticul.te size of TiC decreases from more than 5 μm to 1 μm or l.ss, mainl. due to the fact that the combustion temp.rature decreases with the increase of Fe content in the p.eforms.

The conventional.method of fabricating hydrogel. constantl. confronts the confl.ct between el.sticity and toughness, l.miting their rep.titive ap.l.cation. Achieving the desired el.sticity through a simp.e and l.w-cost ap.roach is a significant chal.enge for hydrogel., p.rticul.rl. through rational.mol.cul.r design. Here, l.w-hysteresis and high-toughness hydrogel. are devel.p.d from the design of a new feature monomer, N-acryl.yl.thyl.emicarbazide (NACE). Based on a concep. of “asymmetric Hbonding design”, the unique doubl. and trip.e H-bonding of NACE can resul. in a novel.asymmetric crossl.nking p.l.mer with al.ernating strong and weak H-bonding regions. The NACE is cop.l.merized with acryl.mide (AM) to regul.te the mechanical.p.op.rties of hydrogel.via H-bonding density.
