Fabrication and Characterization of Ni Thin Films Using Direct-Current Magnetron Sputtering

Ni films are deposited by using ultra high vacuum dc magnetron sputtering onto silicon substrates at room temperature, and the high-quality and high-density films are prepared. The parameters, such as thickness, density and surface roughness, are obtained by using small-angle x-ray diffraction (XRD) analyses with the Marquardt gradient-expansion algorithm. The deposition rate is calculated and the Ni single layer can be fabricated precisely. Based on the fitting results, we can find that the surface roughness of the Ni films is about 0.7nm, the densities of Ni films are around 97% and the deposition rate is 0.26nm/s. The roughness of the surface is also characterized by using an atomic force microscope (AFM). The changing trend of the surface roughness in the simulation of XRD is in good agreement with the AFM measurement.     

ULTIMATE BOUNDEDNESS FOR A DIFFERENTIAL DELAY MODEL

This paper considers the scalar differential delay equation x(t) = -μx(t)-f(x(t-Τ(t)), t). By using the mapping method we obtain that the solutionswill be ultimately in some interval.     

聚合物复合膜的制备及吸液性能

由聚丙烯（PP）、聚乙烯（PE）制成的单层或多层微孔膜（PP，PP／PE／PP）具有良好的机械强度，且具备自关闭功能，已被广泛用作液态锂离子电池的隔膜，但PP，PP／PE／PP等微孔膜表面能低，难与塑料电极真正复合为一体，不能直接用于聚合物锂离子电池。因此在PP，PP／PE／PP等微孔膜表面涂敷一层具有黏结性质的过渡薄膜，兼顾两种材料的优点，有助于提高机械强度和将电极粘结起来的黏结力。聚合物复合膜是一种具有3层结构的复合膜，由两外层膜及中间膜组成。正丁醇不溶胀PVDF—HFP，可以丁醇为介质来测量复合膜的吸液率，该数据可作为膜孔率高低的判据，也可用于粗略判断膜电导率高低。
