Scanning transmission x-ray microscopy of isolated multiwall carbon nanotubes

Applied Physics Letters, 2006
Scanning transmission x-ray microscopy (STXM) has been used to study isolated carbon nanotubes for the first time. STXM and transmission electron microscopy were applied to the same type of nanotubes, providing unique information about their composition, and electronic and structural properties.

Scanning Transmission X-Ray Microscopy

2018
Scanning transmission X-ray microscopy (STXM) is a method to obtain a microscopic image of the raster-scanned sample by detecting the transmission intensity of the focused X-rays. As drawn in Fig. 96.1, a Fresnel zone plate (FZP) is often used to focus the soft X-rays from the synchrotron radiation sources (Attwood in Soft X-rays and Extreme ...

Scanning transmission X‐ray microscopy study of microbial calcification

Geobiology, 2004
ABSTRACTCalcium phosphates and calcium carbonates are among the most prevalent minerals involved in microbial fossilization. Characterization of both the organic and mineral components in biomineralized samples is, however, usually difficult at the appropriate spatial resolution (i.e. at the submicrometer scale). Scanning transmission X‐ray microscopy (

Chemical component mapping of pulverized toner by scanning transmission X-ray microscopy

Micron, 2006
Toners are micron scale polymer particles constructed of several kinds of resin, pigment, wax, etc. Transmission electron microscopy (TEM) is used for observation of the dispersion of the component materials in toners, but TEM images cannot identify simultaneously all components.

Scanning Transmission X-Ray Microscopy of Hydrated Mitotic Chromosomes

1992
Images of fully hydrated mitotic chromosomes from Vicia faba were recorded on the Scanning Transmission X-ray Microscope at 110, 85, 60, and 35 mM ionic strengths. The images revealed an increase in chromosome diameter and length as the salt concentration was reduced, in agreement with findings from visible light microscopy.

Quantitative analysis of mammalian chromosome by scanning transmission soft X-ray microscopy

Ultramicroscopy, 2018
Soft X-ray spectromicroscopy was applied to study the quantitative distribution of DNA and protein in a mammalian chromosome at the spatial resolution of 100 nm. The quantities of DNA and protein were evaluated using 1s-π* transition in the NEXAFS spectra at the nitrogen K absorption edge.

Scanning transmission x-ray microscopy (STXM) of plutonium oxide

Journal of Vacuum Science & Technology A
Scanning transmission x-ray microscopy was used to examine plutonium oxide particles formed by the corrosion of δ-phase plutonium alloy under high-humidity conditions. O K-edge spectra collected from eight distinct particles displayed significant spectral differences, revealing heterogeneity in oxidation states within a single sample batch.

Soft X‐ray microscopy with a cryo scanning transmission X‐ray microscope: I. Instrumentation, imaging and spectroscopy

Journal of Microscopy, 2000
We have developed a cryo scanning transmission X‐ray microscope which uses soft X‐rays from the National Synchrotron Light Source. The system is capable of imaging frozen hydrated specimens with a thickness of up to 10 μm at temperatures of around 100 K.
