Direct electrochemical reduction of mixed TiO2 and NiO powders to TiNi alloy has been successfully demonstrated in molten CaCl2 at 900℃ by constant voltage electrolysis. The electrolysis en- ergy consumption was as low as 23.4 kWh/kg-TiNi, although the current efficiency was 20.5% in the pre- liminary experiments. During the process, NiO was first reduced to Ni at high speed, accompanied by TiO2 being perovskitized to CaTiO3?x which was gradually reduced to Ni3Ti and TiNi, assisted by the depolarization of the preformed Ni. The cell voltage for preparation of the TiNi alloy was lower than that for Ti. Adjusting the cell voltage not only affected the reduction speed, but also offered a convenient ac- cess to the preparation of the nickel/perovskite composite.

在有限标记样本下,为了有效协同空谱信息提高高光谱图像的分类性能,提出了一种基于自适应字典的小样本高光谱图像分类方法。首先,对高光谱图像进行熵率超像素分割,分析标记样本的超像素区域和光谱近邻,将鉴别力高的样本扩展至标记样本集;然后,在扩展的标记样本集上分析测试样本的空谱信息,对不同的测试样本精简标记样本集,形成自适应字典;最后,在自适应字典上,协同空谱信息重构测试样本,在协同表示中同时考虑重构字典中空谱信息的竞争性。实验结果表明,对比传统的基于光谱的方法和固定窗口尺寸下融合空谱特征的高光谱图像分类方法,在印地安农林数据集上,当训练样本数目仅为样本集数目2%时,本文方法总体分类精度为91.45%,比其他方法高3.48~39.52个百分点;在训练样本数为1%的帕维亚大学数据集上,该方法的总体分类精度达到95.54%,比其他方法高2.45~21.63个百分点,验证了本文方法的有效性。

A simple （2×2） pixelated flexible infrared nanosensor array based on carbon nanoparticles （CNPs） was fabricated through a simple and low-cost flame method. By integrated with a micro controller unit, the sensor array could detect power density of incident infrared light in real-time. The mechanism for the superior infrared sensing property of the flexible sensor array based on CNP was also studied in detail in this work.
