Abstract

Abstract Full‐field transmission x‐ray tomography can obtain 3D morphology and configurations of nanoscale materials. In this study, we further demonstrate the feasibility of this technique using magnetic chains consisting of cobalt mesospheres. The preliminary images presented in this article clearly reveal that three types of cobalt nanoparticles, namely, hollow, core–shell, and solid were found for magnetic chain synthesis. Furthermore, the tomographic analyses revealed the growth mechanism of magnetic chains self‐assembled by cobalt nanoparticles. We may claim that the spatial resolution and contrast characteristics of the full‐field transmission x‐ray tomography can satisfy the research requirements of nanomaterial science. Hence, transmission x‐ray tomography could be a powerful complementary method for imaging and analysis of nanoscale materials.

由钴介球组成的磁链的纳米级分析

全文场透射x射线断层扫描可以获得纳米级材料的三维形态和构型。在本研究中，我们利用钴介球组成的磁链进一步证明了该技术的可行性。本文提供的初步图像清楚地揭示了用于磁链合成的三种类型的钴纳米颗粒，即空心、核壳和固体。此外，层析分析揭示了钴纳米粒子自组装磁链的生长机制。我们可以说，x射线全场透射层析成像的空间分辨率和对比度特性可以满足纳米材料科学的研究要求。因此，透射x射线断层扫描可以成为纳米级材料成像和分析的有力补充方法。

期刊介绍： X-Ray Spectrometry is devoted to the rapid publication of papers dealing with the theory and application of x-ray spectrometry using electron, x-ray photon, proton, γ and γ-x sources. Covering advances in techniques, methods and equipment, this established journal provides the ideal platform for the discussion of more sophisticated X-ray analytical methods. Both wavelength and energy dispersion systems are covered together with a range of data handling methods, from the most simple to very sophisticated software programs. Papers dealing with the application of x-ray spectrometric methods for structural analysis are also featured as well as applications papers covering a wide range of areas such as environmental analysis and monitoring, art and archaelogical studies, mineralogy, forensics, geology, surface science and materials analysis, biomedical and pharmaceutical applications.
