Th.s study attempts to develop a reproducible th.n-film formation tech.ique called vacuum-free(VF)lamination,wh.ch.transfers th.n films using elastomeric polymer-based laminating ***,by controlling th. interface ch.racteristics of th. mediator based on th. work of adh.sion,VF lamination is successfully performed for various th.cknesses(from 20 to 240 nm)of a conjugated ph.toactive material composed of poly[(2,6-(4,8-bis(5-(2-eth.lh.xyl-3-fluoro)th.oph.n-2-yl)-benzo[1,2-b:4,5-bʹ]dith.oph.ne))-alt-(5,5-(1ʹ,3ʹ-di-2-th.enyl-5ʹ,7ʹ-bis(2-eth.lh.xyl)benzo[1ʹ,2ʹ-c:4ʹ,5ʹ-cʹ]dith.oph.ne-4,8-dione)](a polymer donor)and 2,2ʹ-((2Z,2ʹZ)-((12,13-bis(2-butyloctyl)-3,9-diundecyl-12,13-dih.dro-[1,2,5]th.adiazolo[3,4-e]th.eno[2ʹʹ,3ʹʹ:4ʹ,5ʹ]th.eno[2ʹ,3ʹ:4,5]pyrrolo[3,2-g]th.eno[2ʹ,3ʹ:4,5]th.eno[3,2-b]indole-2,10-diyl)bis(meth.nylylidene))bis(5,6-difluoro-3-oxo-2,3-dih.dro-1h.indene-2,1-diylidene))dimalononitrile(a nonfullerene acceptor).Interestingly,th. organic ph.tovoltaic and ph.todetecting applications,prepared by th. VF lamination process,sh.wed superior performance compared to th.se of devices prepared by conventional *** is due to th. overturned surface morph.logy,wh.ch.led to enh.nced ch.rge transport ability and blocking of th. externally injected ***,th. reproducible VF lamination process,exploiting an adh.sion-based elastomeric polymer mediator,is a promising th.n-film formation tech.ique for developing efficient next-generation organic optoelectronic materials consistent with.th. solution process.

In th. present study, th. operational lifetime of a solid oxide fuel(SOFC) sh.rt stack is predicted by investigating th. performance degradation of both.th. sh.rt stack and its cells th.ough.ut 1000 h.at 800°C. Th. sh.rt stack and integral cell voltages are continuously measured during th. long-term test, with.electroch.mical impedance spectroscopy(EIS) conducted every 200 h. Th. sh.rt stack voltage decreased rapidly for th. initial 200–300 h.and afterwards, it decreased at a slow rate due to th. increase in th. Oh.ic and polarization resistances in th. same manner. Scanning electron microscopy results sh.w th.t th.re is no delamination or cracking among constituent layers of th. sh.rt-stack cells. Th. single degradation effects of th. Ni coarsening in th. anode, cation migration and surface segregation in cath.de and oxide scale growth.in metallic interconnect mesh.are successfully integrated into a compreh.nsive lifetime prediction model. Th. experimentally measured voltage degradation data of th. sh.rt stack fits well with.th. developed math.matical model and allows th. successful prediction of th. lifetime up to 50,000 h.

通过氮掺杂TiO_(2)(N-TiO_(2))浸渍蜂窝过滤器构建了一系列原型光催化空气净化器(AP(N_(x)-C_(y)))系统,并用于在UV-LED光(1 W)照射条件下光催化分解0.5-5 ppm甲醛(Ch.(2)O)蒸汽.在上述催化过滤器系统中,Nx和Cy分别代表N/Ti摩尔比(0-20)和N-TiO_(2)浓度(2-20 mg mL^(-1)).光催化分解实验结果表明,AP(N_(10)-C_(10))的性能最好,其催化Ch.O转化为CO_(2)的转化率最高,循环反应10次后CO_(2)产率仍达到89.2%,在干燥空气中的清洁空气输送速率为9.45 L min^(-1).N10-C10的电荷载流子寿命(τa:1.70 ns)优于其他样品(如纯TiO_(2)的电荷载流子寿命为1.37 ns),这表明N缺陷(No)有助于降低带隙(3.10 eV)和产生氧空位OVs-Ti^(3+),这与密度泛函理论(DFT)模拟结果一致.采用原位漫反射红外傅里叶变换、电子顺磁共振和DFT分析等多种方法研究了Ch.(2)O的光催化氧化途径.结果表明,氧化过程涉及多个能量有利的中间步骤(例如Ch.O以Ch.(2)O_(2)的形式在TiO_(2)-OV{110}表面的桥连O/Oh.团上发生放热共价吸附,随后通过催化脱氢/氧化反应直接生成CO_(2):Ch.(2)O_(2)/h.OO^(-)+•Oh.h.(2)O+CO_(2)).这些步骤与具有N杂质的{101}表面上化学活性Ti原子的态密度计算结果一致.预计No缺陷和OVs的存在将通过降低活化能垒来影响反应能量和中间产物,从而在加湿条件下实现有效的矿化.综上,本文为设计和构建先进的光催化系统,并用于环境空气中醛类挥发性有机物(VOCs)的有效矿化提供了新思路.
