Nano-structured photon management is currently an interesting topic since it can enhance the optical absorption and reduce the surface reflection which will improve the performance of many kinds of optoelectronic devices, such as Si-based solar cells and light emitting diodes. Here, we report the fabrication of periodically nano-patterned Si structures by using polystyrene nano-sphere lithography...
In this paper, we used the CHINA-VALS scale to analysis the influence of the values and lifestyle on China's mobile phone buyers. On the basis of survey data, through factor analysis and K-means cluster analysis this paper segment consumer into four groups; Next, we researched the demographic factors and product purchase intention in use of chi-square tests; Finally, we did chiasma analysis on the...
With the rapid development of the network technology and education technology, network education is developing quickly. The development of network education promotes the research and development of a variety of software and systems supporting network education. But most of the existing network education supporting systems lack of personalized learning environment and are less intelligent, which can...
4-Nitro-4 -amino-biphenyl (p-NBA), a photo- and thermostable chromophore with high nonlinear optical (NLO) activity, was used to react with various epoxy resins, then three linear functionalized epoxy polymers were obtained and further crosslinked with a trimer of hexamethylene diisocynate during poling process. The second harmonic generation behaviors of linear and crosslinked poled polymers have...
