在这项研究中,利用正交测量技术的组合来预测胶体纳米棒的平均长度和直径。沉降系数分布和电迁移率分布,分别从分析ultracenthagation和扫描迁移率粒度仪,用于流体动力学相关。该方法在理论上得到了验证,并应用于Au和ZnO纳米棒样品。结果表明,这两种测量技术的组合是一个很好的方法,纳米棒的二维表征。
A combination of orthogonal measurement techniques is utilized in this study to predict the average lengths and diameters of colloidal nanorods. Sedimentation coefficient distributions and electrical mobility distributions obtained from analytical ultracentrifugation and a scanning mobility particle sizer, respectively, are used for the hydrodynamic correlation. The method is validated theoretically and application to Au and ZnO nanorod samples is shown. The results demonstrate that the combination of both measurement techniques is an excellent method for the two-dimensional characterization of nanorods.
