Direct Determination of Dissolution Rates at Crystal Surfaces Using 3D X-ray Microtomography

ACS Earth and Space Chemistry, 2018
Investigations of mineral surface reactivity have recently challenged the classical approach of determining dissolution rates from mineral powders as crystals often exhibit heterogeneous and/or anisotropic reactivity.

X-ray microtomography of bones and teeth

Physiological Measurement, 1996
X-ray microtomography is a miniaturized version of computerized axial tomography with a resolution of the order of micrometres. In the biomedical field it is particularly useful in the study of hard tissue because of its ability to accurately measure the linear attenuation coefficient.

X-ray microtomography of materials

International Materials Reviews, 1999
X-ray microtomography allows imaging of the interior microstructure of materials non- destructively and with spatial resolution which can approach that of optical microscopy (typically, no better t...

Description of Ore Particles from X-Ray Microtomography (XMT) Images, Supported by Scanning Electron Microscope (SEM)-Based Image Analysis

Microscopy and Microanalysis, 2018
In this paper, three-dimensional (3D) image data of ore particle systems is investigated. By combining X-ray microtomography with scanning electron microscope (SEM)-based image analysis, additional information about the mineralogical composition from ...

Hard X-Ray Microtomography Using X-Ray Imaging Optics

Japanese Journal of Applied Physics, 2001
The first experiment to test the hard X-ray microtomography using X-ray imaging optics was carried out at the undulator beamline BL47XU of SPring-8. A Wolter type grazing incidence mirror was used as an objective. A charge coupled device (CCD) camera coupled with a phosphor screen and a relay lens (pixel size: 6 µm×6 µm, spatial resolution: 12.3 µm

Desktop X-ray microscopy and microtomography

Journal of Microscopy, 1998
Recent developments in X‐ray microtomography have made it possible to miniaturize a CT scanner into a versatile and cost‐effective desktop system that fits into any laboratory environment. The possibilities of the technique are demonstrated for a range of applications. It is also shown how an existing scanning electron microscope with an X‐ray detector

X-ray Microtomography of Ceramic Artifacts

MRS Proceedings, 1995
In this paper we describe the analysis of ceramic artifacts with a new type of three dimensional x-ray microscopy which can have micron spatial resolution. The x-ray microscopy is based on a microtomographic technique which reconstructs the three dimensional structure of millimeter sized specimens from high resolution digital radiographs of the ...
