In this paper, In2O3/SnO2 thin films deposited on the fabric for camouflage net are developed. Effect of the film thickness on the spectral reflective properties is investigated thoroughly. Results of the influence of the film thickness on the morphology and spectral properties are presented. Application of In2O3/SnO2 film in the infrared camouflage field is proposed. © Chin.Phys.Soc.

Conductive films with high transmittance in both visible and infrared regions were prepared using treated polyethylene (PE) films as the substrate and poly(3, 4-ethylenedioxythiophene) (PEDOT) as the conductive substance by screw coating method. Then the transmittance and conductivity of conductive films were investigated by UV-vis spectroscopy, IR and four-point probe method. The results indicate that the surface hydrophilicity of PE films can be improved significantly after coating modifications. Both the modified layer and the conductive layer show little influence on the transmittance of the visible light while decrease the infrared transmittance of PE conductive films. When the mass fraction of ultraviolet light solid glue CBU225 is 20% and the PEDOT emulsion is doped with 5% dimethyl sulfoxide (DMSO), the conductive films exhibit a surface resistance of 8640Ω and a transmittance in 550 nm of 75.8% together with the highest transmittance in infrared region.

Ruthenium doped nanostructured lithium titanates have been synthesized through a reverse microemulsion method with a subsequent sintering process. The as-prepared powders are characterized by the X-ray diffraction and transmission electron microscope techniques. The results indicate that a solid solution of Li4Ti5 - xRuxO 12 is formed when x was less than 0.1. The electrochemical performances of the as-prepared materials are investigated in a potential range from 0.01 to 2.5 V by charge and discharge characterizations. In that, the as-prepared Li4Ti4.95Ru0.05O12 exhibits an excellent electrochemical performance. The specific discharge capacity remains as 131 mAh g-1 over 100 cycles even cycled at a large density of 17,500 mA g-1 (60 C-rate). While the current density decreases to be 875 mA g-1(3 C-rate), the corresponding specific discharge capacity is kept as high as 259 mAh g-1 after 100 cycles. © 2012 Published by Elsevier B.V.

The current problem with the detection of trace metal targets underground such as anti-personnel landmines lies in the shortage of suppression capability of the soil background interference and extraction accuracy of the abnormal target signal. In response to these issues, the staple principle of the frequency-domain electromagnetic method in the geophysics and measured data is researched; on this basis, a processing algorithm is developed that eliminates the soil background interference with sensor driven by multi-frequency signal, and this algorithm is deduced and proved. The cross-correlation algorithm and FPGA are applied to the sensor signal processing, which implements digital signal processing and effectively improves the signal to noise ratio of the received signal and extraction accuracy. A special test instrument is developed and used to verify algorithm on the soil-bins that is stuffed with typical kind of soil, and the comparative test results on the magnetic soil which produce the toughest background interference indicate that target signal could be picked up effectively from background interference, accordingly the algorithm is proved to be feasible. © 2015 ISSN.
