Abstract

Higher-order statistical analysis of X-ray scattering from dilute solutions of polydisperse goethite nanorods was performed and revealed structural information which is inaccessible by conventional small-angle scattering. For instance, a pronounced temperature dependence of the correlated scattering from suspension was observed. The higher-order scattering terms deviate from those expected for a perfectly isotropic distribution of particle orientations, demonstrating that the method can reveal faint orientational order in apparently disordered systems. The observation of correlated scattering from polydisperse particle solutions is also encouraging for future free-electron laser experiments aimed at extracting high-resolution structural information from systems with low particle heterogeneity.

摘要

对多分散针铁矿纳米棒稀溶液的X射线散射进行了高阶统计分析，揭示了传统小角散射无法获得的结构信息。例如，观察到悬浮液相关散射存在明显的温度依赖性。高阶散射项偏离了粒子取向完全各向同性分布所预期的值，表明该方法可以揭示明显无序系统中微弱的取向有序性。多分散粒子溶液相关散射的观测结果对于未来旨在从低粒子异质性系统中提取高分辨率结构信息的自由电子激光实验也很有鼓舞作用。
