X-ray computed microtomography of Megachirella wachtleri [PDF]
Scientific Data, 2018 AbstractUnderstanding the origin and early evolution of squamates has been a considerable challenge given the extremely scarce fossil record of early squamates and their poor degree of preservation. In order to overcome those limitations, we conducted high-resolution X-ray computed tomography (CT) studies on the fossil reptile Megachirella wachtleri ...

Using small-angle X-ray scattering to investigate the compaction behaviour of a granulated clay [PDF]
, 2015 The compaction behaviour of a commercial granulated clay (magnesium aluminium smectite, gMgSm) was investigated using macroscopic pressure-density measurements, X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray microtomography (XμT) and ...

Phase-contrast X-ray microtomography of mouse fetus
Biology Open, 2012 Summary A phase-contrast X-ray microtomography system using the Talbot imaging has been built at the SPring-8 synchrotron radiation facility. This system has much higher density resolution than absorption-based X-ray microtomography.

Morphological characterization of a polymeric microfiltration membrane by synchrotron radiation computed microtomography [PDF]
, 2007 Most commercial polymeric membranes are prepared by phase inversion. The performance of the membranes depends greatly on the morphology of the porous structure formed during the different steps of this process.

Microfocus X-ray sources for 3D microtomography [PDF]
, 1994 An analytic model for the performance of cone beam microtomography is described. The maximum power of a microfocus X-ray source is assumed to be approximately proportional to the focal spot size.

First diagnosis of septic arthritis in a dinosaur [PDF]
Royal Society Open Science, 2016 Identification and interpretation of pathologies in the fossil record allows for unique insights into the life histories of extinct organisms. However, the rarity of such finds limits not only the sample size for palaeopathologic studies, but also the ...
