摘要

分光光度法被用于实现x射线光谱显微镜的空间分辨率的显着改进，允许在更细的空间尺度上进行化学微量分析。近边缘x射线吸收精细结构(NEXAFS)的化学灵敏度是大多数使用x射线光谱显微镜进行化学微量分析的研究人员所熟悉的。然而，通过压型图获得的额外相信息提供了额外的和诱人的数据，以及潜在的额外化学信息。本文探讨了二氧化硅纳米球体系的相化学信息。

Making chemical sense of phase in soft X-ray spectroptychography

Spectroptychography is being used to realize a significant improvement in the spatial resolution of x-ray spectromicroscopy, allowing chemical microanalysis at finer spatial scales. The chemical sensitivity of near edge X-ray absorption fine structure (NEXAFS) is familiar to most researchers who use x-ray spectromicroscopy for chemical microanalysis. However, the additional phase information available through ptychography provides additional and tantalizing data, and potentially additional chemical information. This paper explores the chemical information available in phase for a system of silicon dioxide nanospheres.

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
