Algorithm of Amorphous Carbonaceous Nanomaterial Structure Identification with a Joint X-Ray and Neutron Diffraction Data Analysis
摘要:
开发了一种用于无定形碳纳米材料的结构识别的算法,该算法具有联合X射线和中子衍射数据分析,使用来自其他诊断的样品的化学组成的数据。该算法是以前开发的用于类似纳米材料的X射线衍射诊断的算法的扩展([1] Chem.Phys.Lett.,506,265-268(2011))。该算法是测试的例子处理的计算数据的样本,其中模型的碳氢化合物薄膜的片段在[1]中分析。该算法是感兴趣的碳和氢的原子分数可比的材料的结构诊断。
英文摘要:
An algorithm is developed for structure identification of amorphous carbonaceous nanomaterials with a joint x-ray and neutron diffraction data analysis, using the data on the chemical composition of the sample from other diagnostics. The algorithm is an extension of one formerly developed for the x-ray diffraction diagnostics of similar nanomaterials ([1] Chem. Phys. Lett., 506, 265-268 (2011)). The algorithm is tested on the example of processing the computed data for a sample which models a fragment of hydrocarbon films analyzed in [1]. The algorithm is of interest for structure diagnostics of materials with comparable atomic fractions of carbon and hydrogen.
