Phase-field modeling of micropore formation in a solidifying alloy

Hossein Meidani

This thesis is focused on the study of the morphology of micropores formed during solidification of metallic alloys. Micropores constrained to form in well-developed dendritic solid network adopt complex non-spherical shapes. Previous studies using X-ray t ...

Gold nanoparticles as high-resolution X-ray imaging contrast agents for the analysis of tumor-related micro-vasculature

Giorgio Margaritondo

Background: Angiogenesis is widely investigated in conjunction with cancer development, in particular because of the possibility of early stage detection and of new therapeutic strategies. However, such studies are negatively affected by the limitations of ...

Topology of evolving pore networks

Emmanuel Gallucci, Marco Stampanoni

Morphological and topological quantification of complex pore networks is of great relevance for environmental engineering, earth science and industry. Recent developments of 3D imaging techniques such as X-ray microtomography or X-ray microscopy provide an ...

Curvature of micropores in Al-Cu alloys: An X-ray tomography study

Michel Rappaz, Milan Felberbaum

Micropores formed in Al-Cu alloys cast under controlled conditions have been analyzed using high-resolution X-ray tomography. The influence of inoculation conditions, copper content, cooling rate and initial hydrogen content on the morphology of pores has ...

An X-ray computed tomography-based index to characterize the quality of cataclastic carbonate rock samples

Aurèle Parriaux, Pascal Turberg, Reto Meuli, Vincent Labiouse, Pierre Guillaume Christe

X-ray computed tomography (XRCT) can reconstruct, in a nondestructive way and in three-dimension, the distribution of densities within opaque materials. Consequently, it provides an effective possibility to characterize the inner content of rock core sampl ...

Symbios SPS-standard and custom stem micromotion comparison by micro- CT imaging

Vu Thanh-Hieu Nguyen

The aim of this study is to compare the difference in µ-motion between a custom stem implant and a sps standard stem and assess the importance of patient specificity. A surgeon would implant 3 sps-standar stems and 3 custom stems in 6 cadaveric femurs. The ...

Connectivity of Phases and Growth Mechanisms in Peritectic Alloys Solidified at Low Speed: an X-Ray Tomography Study of Cu-Sn

Michel Rappaz, André Phillion, Jonas Valloton, Marco Stampanoni

The variety of microstructures that form at low solidification speed in peritectic alloys, bands, and islands, or even coupled (or cooperative) growth of the primary alpha and peritectic beta phases, have been previously explained by nucleation-growth mech ...
