Electrocatalytic oxygen reduction reaction(ORR)and hydrogen evolution reaction(HER)in acidic media are vital for the applications of renewable energy ***,the low mass activity of noble Pt urgently needs to be improved due to the strong binding energetics of oxygen species(*O)with Pt *** we report fine PtxSr alloy(-2 nm)supported on N-doped carb on(NC)pyrolyzing from ZIF-8 as bifunctional electrocatalysts toward ORR and HER in acidic *** representative Pt_(2)Sr/NC exhibits an onset potential of 0.94 V *** and half-wave potential of 0.84 V toward ORR,and a low over-potential of 27 mV(10 mA cm^(-2))toward HER,***,the mass activities of Pt_(2)Sr/NC are 6.2 and 2.6 times higher than that of Pt/C toward ORR(at 0.9 V)and HER(at-30 mV),***,Pt_(2)Sr/NC possesses a retention rate of 90.97%toward acidic ORR after 35000 s of continuous *** density functional theory(DFT)calculations and X-ray photoelectron spectroscopy analysis,the incorporation of Sr into Pt forming Pt_(2)Sr alloy redistributes the electronic structures of Pt-Pt bonds,changing the rate-determining step for the ORR on Pt sites from the formation of*OH from*O to the generation of*OOH along with decreasing the energy barrier,which is also confirmed by the downshift of d band ***,the downshift of d band center also leads to the optimization of the adsorption energy(H*)with Pt,significantly improving Pt_(2)Sr/NC toward HER.

作者： su zhiwei CHEN Qingchuan

Ion beam technology is used widely in many fields such as electric, material, optics, medicine, biology and so on. At the same time, it brings some huge technological effects and economical benefits, especially for the optical applocations. According for the technology, the properties of high accuarate spectral analyzer also can be improved by manufacturing the lage-area holographic ion beam eathing（HIBE） grating. Simultaneously, as one of the parts of ion beam technology, the developments of ion beam sources have some important effects to content the demands of ion beam technology such as large ion beam flux, excellent optical qualities. In this paper, an ion beam source called inductively coupled plasma（ICP） ion beam source was introduced, and the extractor system, the application prospect were also discussed.

Objective:To coat a zirconia surface with silica-zirconia using a dip-coating technique and evaluate its effect on resin-zirconia shear bond strength(SBS).Methods:A silica-zirconia suspension was prepared and used to coat a zirconia surface using a dip-coating *** hundred and eighty-nine zirconia disks were divided into three groups according to their different surface treatments(polishing,sandblasting,and silica-zirconia coating).Scanning electron microscopy(SEM),energy dispersive X-ray(EDX),and X-ray diffraction(XRD)were used to analyze the differently treated zirconia *** primer treatments(Monobond N,Z-PRIME Plus,and no primer)were also applied to the zirconia ***,180 composite resin cylinders(Filtek Z350)were cemented onto the zirconia disks with resin cement(RelyX Ultimate).The SBS was measured after water storage for 24 h or 6 *** data were analyzed by two-way analysis of variance(ANOVA).Results:SEM and EDX showed that the silica-zirconia coating produced a porous layer with additional Si,and XRD showed that only tetragonal zirconia was on the silica-zirconia-coating *** with the control group,the resin-zirconia SBSs of the,andblasting group and silica-zirconia-coating group were significantly increased(P<0.05).The silica-zirconia coating followed by the application of Monobond N produced the highest SBS(P<0.05).Water aging significantly reduced the resin-zirconia SBS(P<0.05).Conclusions:Dip-coating with silica-zirconia might be a feasible way to improve resin-zirconia bonding.

上海广东浸信会是20世纪上半叶由旅沪粤籍浸信会信徒构成的移民宗教团体。它诞生于基督教在华传播中与地缘性移民社会的互动,并在近代上海城市中为粤人移民开辟了宗教空间,介入移民再社会化过程,混合宗教因素和同乡因素,构建起粤人信徒独有的同乡网络,在某些方面发挥着传统同乡组织的职能。上海广东浸信会的系列活动揭示了基督教传播中较特殊的“同乡与同信仰”活动模式,在粤人移民网络中展示了移民作为宗教跨境传播的载体力量,也呼应着基督教中国化的趋势,将中国传统乡土意识、近代民族意识和西方宗教文化融合。

关键词：粤人浸信会移民与宗教同乡教会同乡与同信仰基督教中国化
