To reduce the cost of manufacture,it is urgent to develop effi-cient and stable platinum(Pt)-free counter electrode(CEs)electrocatalysts for dye-sensitized solar cells(DSSCs).In this study,a simple electrospinning and carbonization strategy has been developed to synthesize carbon nanofibers(CNFs)loaded with Ni and Mo2C nanoparticles(Ni/Mo2C/CNFs)as CE.Owing to the high electrical conductivity of CNFs and the large catalytic activity of Ni and Mo2C,an excellent electrochemical performance of Ni/Mo2C/CNFs as CE is achieved.The optimized DSSC assembled with Ni/Mo2C(2:1)/CNFs-based CE exhibits a power conversion effi-ciency(PCE)of 8.90％,which exceeds the corresponding values of the device using the Pt(8.07％),Ni/Mo2C(1∶1)/CNFs(8.68％),Ni/Mo2C(1∶2)/CNFs(8.20％),Ni/CNFs(7.50％)and Mo2C/CNFs(6.10％).This work provides a new strategy for developing effective and low-cost CE materials in DSSCs.

室内家具散发的挥发性有机物(VOC)对空气质量有重要影响.家具中VOC的散发特性可由初始可散发浓度C0、扩散系数Dm和分配系数K表征,因此测定三大关键参数是揭示散发机理的基础.此外,环境条件也是影响散发的重要因素.本文选用板式家具,首先建立了双层数值模型,然后提出了能够同时测定三大关键参数的多参数拟合法,并开展实验测试获得了典型VOC的关键参数值.同时以温度为变量条件,分析了温度对散发过程的影响规律.结果 表明,随着温度的升高,Dm增大,K减小,C0呈非单调变化.
低维化是提高材料热屯性能的有效方法.本文采用基于密度泛函理论的第一性原理和形变势理论,研究了MoS2/WS2异质结的能带结构和热电性能.研究结果表明异质结具有1.10 eV的间接带隙,且堆叠方式对异质结的能带结构影响较小.双轴应变可以起到能带调控的作用,并进一步影响塞贝克系数和电导率.n型和p型掺杂体系的功率因子分别在1％和3％的压缩应变情况下得到显著提高.研究证实了施加双轴应变是提高异质结热电性能的有效方法.
随着飞行器性能的提升,其高效热管理的重要性日益凸显,因而整体热管理系统逐渐得到广泛应用.本文以一种典型的飞行器整体热管理系统为研究对象,通过引入热阻、热动势和能量源等部件构建其热量流模型,应用基尔霍夫定律获得系统中能量的整体输运与转换规律,并明确系统性能和各设计、运行参数间的直接约束关系.以此为基础并结合遗传算法,以热管理系统的总体轻量化为目标,实现了其多参数全局优化.优化结果表明只依赖经验的系统设计容易错失最优解.
本文针对燃料预着火问题,对文献预着火实验和理论做了梳理,对比激波管中典型NTC燃料DME在不同当量比下着火实验数据.从燃料基础化学特性着手,结合着火延迟期温度微扰动敏感性、热耗散特征以及反应时间尺度特征进行预着火过程理论分析,明晰了温度微扰动敏感性和反应时间尺度特征是预着火发生的主导性因素.研究发现,DME和正庚烷在稀当量比、低压、低燃料浓度时更容易发生预着火.为判断和解析其它燃料预着火现象发生条件和发生机制提供理论参考.
通过分析“实践十号”卫星长时间微重力下单颗粒煤燃烧实验的彩色和红外图像,获得了单颗煤粒在各向同性燃烧条件下周围碳烟辐射强度分布,同时使用瞬态燃烧模型对实验进行模拟,进一步揭示了煤颗粒周围的碳烟浓度分布规律及其控制因素.实验和模型研究表明,2 mm煤颗粒在(1.5～7)r0处存在碳烟.挥发分燃烧中期,当氧气质量分数低于8％且气体温度高于1400 K时,颗粒周围的碳烟辐射强度和体积分数沿径向均呈双峰分布,而常重力下实验受自然对流影响呈现单峰分布.
