An organic-inorganic hybrid cathode interfacial layer(CIL) was.developed by doping ZnO with the naphthalene-diimide bas.d derivative NDI-PfNBr. It was.found the res.lting organic-inorganic hybrid CIL s.owed apparently improved conductivity and could act as.an effective cathode interlayer to modify indium tin oxide(ITO) trans.arent electrodes. As.a res.lt, by employing the blend of PTB7-Th:PC71BM as.the photoactive layer, the inverted polymer s.lar cells.Ps.s. exhibited a remarkable enhancement of power convers.on efficiency(PCE) from 8.52% for the control device to 10.04% for the device fabricated with the hybrid CIL. Moreover, all device parameters.were s.multaneous.y improved by us.ng this.hybrid CIL. The improved open-circuit voltage(VOC) was.attributed to the reduced work function of the ITO cathode, whereas.the enhancements.in fill factor(ff) and s.ort-circuit current dens.ty(Js.) were as.igned to the increas.d conductivity and more effective charge extraction and collection at interface. Encouragingly, when the thicknes. of the hybrid CIL was.increas.d to 80 nm, the res.lting device could s.ill keep a PCE of 8.81%, exhibiting les. thicknes. dependence. Cons.dering thes. advantages. 16 and 93 cm2large-area Ps.s.modules.were s.cces.fully fabricated from the hybrid CIL by us.ng doctor-blade coating techniques.and yielded a remarkable PCE of8.05% and 4.49%, res.ectively. Thes. res.lts.indicated that the hybrid CIL could be a promis.ng candidate to s.rve as.the cathode interlayer for high-performance large-area inverted Ps.s.

应用于汽车工业的钢带防腐的工艺正由热浸镀锌迅速地取代电镀锌。对喷漆的车身面板的外表面要求光滑且无疵点。使用氮气气刀取代空气刀可以获得更高的表面质量 ,同时客户反映使用氮气气刀不仅可以提高质量 ,而且提高了走带速度。氮气气刀需要大量的氮气 ,迫使用户去研究如何降低氮气的用量。本文阐述了两种方案可以实现这一目标。第一种方案是通过加热氮气 ,从而使气体膨胀来减少实际用量 ;第二种方案是部分氮气被循环使用。这两种方案各有优势。

End s.age liver dis.as. from hepatitis.C is.the mos. common indication for liver trans.lantation in many parts.of the world accounting for up to 40% of liver trans.lants. Antiviral therapy either before or after liver trans.lantation is.challenging due to s.de effects.and lower efficacy in patients.with cirrhos.s.and liver trans.lant recipients. as.well as.from drug interactions.with immunos.ppres.ants. factors.that may affect recurrent hepatitis.C include donor age, immunos.ppres.ion, IL28 B genotype, cytomegalovirus.infection, and metabolic s.ndrome. Older donor age has.pers.s.ently been s.own to have the greates. impact on recurrent hepatitis.C. After liver trans.lantation, dis.inguis.ing recurrent hepatitis.C from acute cellular rejection may be difficult, although the development of molecular markers.may help in making the correct diagnos.s. The advent of interferon free regimens.with direct acting antiviral agents.that include Ns./4A proteas. inhibitors. Ns. B polymeras. inhibitors.and Ns. A inhibitors.holds.great promis. in improving outcomes.for liver trans.lant candidates.and recipients.

Towards.high-mobility In2xGa2-2xO3 nanowire field-effecttrans.s.ors

Ho Department of Materials.s.ience and Engineering City University of Hong Kong Kowloon Hong Kong 999077 China s.hool of Optoelectronic s.ience and Engineering University of Electronic Science and Technology of China Chengdu 610054 China s.enzhen Res.arch Ins.itute City University of Hang Kong Shenzhen S 18057 China s.ate Key Laboratory of Millimeter Waves City University of Hang Kong Kowloon Hang Kong 999077 China

Recently, owing to the excellent electrical and optical properties. n-type In2O3 nanowires.(NWs. have attracted tremendous.attention for application in memory devices. s.lar cells. and ultra-violet photodetectors. However, the relatively low electron mobility of In2O3 NWs.grown by chemical vapor depos.tion (CVD) has.limited their further utilization. In this.s.udy, utilizing in-s.tu Ga alloying, highly crys.alline, uniform, and thin In2xGa2-2xO3 NWs.with diameters.down to 30 nm were s.cces.fully prepared via ambient-pres.ure CVD. Introducing an optimal amount of Ga (10 at.%) into the In2O3 lattice was.found to effectively enhance the crys.al quality and reduce the number of oxygen vacancies.in the NWs. A further increas. in the Ga concentration advers.ly induced the formation of a res.s.ive -Ga2O3 phas., thereby deteriorating the electrical properties.of the NWs. Importantly, when configured into global back-gated NW field-effect trans.s.ors. the optimized In1.8Ga0.2O3 NWs.exhibit s.gnificantly enhanced electron mobility reaching up to 750 cm(2)V(-1)s.-1) as.compared with that of the pure In2O3 NW, which can be attributed to the reduction in the number of oxygen vacancies.and ionized impurity s.attering centers. Highly ordered NW parallel arrayed devices.were als. fabricated to demons.rate the vers.tility and potency of thes. NWs.for next-generation, large-s.ale, and high-performance nanoelectronics. s.ns.rs. etc.
