The synthesis, characterization and liquid crystal properties of a homologous series of new tridentate 5-((4-nalkoxyphenyl) azo)-N-(3-ydroxypropyl) salicylaldimine ligands (alkoxy = octloxy, decyloxy, dodecyloxy and tetradecyloxy) and their dicopper(II) complexes are reported. These ligands were prepared by the condensation of the 5-((4-nalkoxyphenyl)azo)salicylaldehydes homologous with 3-amino-1-propanol. The ligands and their dicopper complexes have been characterized by IR, 1H NMR, mass spectroscopy and elemental analyzes. The liquid crystalline properties of the ligands and the related dicopper complexes were studied by differential scanning calorimetry (DSC) and by using a polarizing microscope equipped with a heating and cooling stage. None of the free ligands exhibit liquid crystalline behavior but all of the dicopper complexes demonstrate a smectic A mesophase. 相似文献

Global existence and boundedness of classical solutions for a chemotaxis model with consumption of chemoattractant and logistic source 下载免费PDF全文
This paper deals with the following chemotaxis system: under homogeneous Neumann boundary conditions in a bounded domain with smooth boundary. Here, δ and χ are some positive constants and f is a smooth function that satisfies with some constants a ?0,b > 0, and γ > 1. We prove that the classical solutions to the preceding system are global and bounded provided that Copyright © 2016 John Wiley & Sons, Ltd. 相似文献

A computational and experimental approach is undertaken to study the enhancement of convective heat transfer in fully-developed internal flows by an electrically-induced secondary flow field. Using longitudinal flat electrodes along a parallel-plate configuration, the corona discharge is employed to generate an electrically induced secondary flow on the cross section of the flow passage. The electrically-induced secondary flow forms a swirling flow field in the fully-developed condition and enhances the heat transfer significantly. The flow field was solved computationally and the results were verified and validated by grid refinement study and computational error analysis. 相似文献
