Fabrication of silicon oxide nanodots with an areal density beyond 1 teradots inch(-2)

The combination of solvent annealing, surface reconstruction, and a tone-reversal etching procedure provides an attractive approach to utilize block copolymer (BCP) lithography to fabricate highly ordered and densely packed silicon oxide nano-dots on a surface. The obtained silicon oxide nano-dots feature an areal density of 1.3 teradots inch(-2) .     

An emerging pore-making strategy: confined swelling-induced pore generation in block copolymer materials

Block copolymers (BCPs) composed of two or more thermodynamically incompatible homopolymers self-assemble into periodic microdomains. Exposing self-assembled BCPs with solvents selective to one block causes a swelling of the domains composed of this block. Strong swelling in the confinement imposed by the matrix of the other glassy block leads to well-defined porous structures via morphology reconstruction. This confined swelling-induced pore-making process has emerged recently as a new strategy to produce porous materials due to synergic advantages that include extreme simplicity, high pore regularity, involvement of no chemical reactions, no weight loss, reversibility of the pore forming process, etc. The mechanism, kinetics, morphology, and governing parameters of the confined swelling-induced pore-making process in BCP thin films are discussed, and the main applications of nanoporous thin films in the fields of template synthesis, surface patterning, and guidance for the areal arrangements of nanomaterials and biomolecules are summarized. Recent, promising results of extending this mechanism to produce BCP nanofibers or nanotubes and bulk materials with well-defined porosity, which makes this strategy also attractive to researchers outside the nanocommunity, are also presented.     

一种改进的SUSAN兴趣点检测算法

兴趣点是图像中重要的几何特征,兴趣点的准确检测对于图像处理具有重要意义。为了优化SUSAN算法,提高算法的有效性,对SUSAN兴趣点检测算法中阈值的确定提出了改进。在图像每个像素的SUSAN模板中首先计算阈值t的初值,在利用迭代法获得终值,使其在各种不同的对比度下仍能正确检测兴趣点。实验结果证明了该方法的有效性。
