THE phenomenon of intercrystalline attack by liquid metals on solid metallic crystalline aggregates is well known 1, but the recorded cases which we have been able to find are chiefly of the ...

Challenges still remain to understand the complex chemistry of the intercrystalline boundaries and surface chemistry of the films and to learn how best to exploit them. This material will be keeping ...

In the northern Gulf of Gabes, the Nummulite barrier of the Reineche Member (SW of the Kerkennah archipelago) demonstrates substantial reservoir quality improvement, with porosity reaching up to 30% ...

We study deformation and metamorphic processes in the Earth at all scales, from nanostructures to plate boundaries, using tools ranging from electron microscopy to field geology. Our investigations ...

The stage is adjustable in x-y-z dimensions and can be tilted allowing irregularly shaped samples to be accommodated. XRD is an important tool for determining the intercrystalline structures of ...

On this page, we aim to provide an overview of all PhD dissertations in the Department of Earth Sciences and its Utrecht predecessors. Since 2011, Utrecht Studies in Earth Sciences (USES) is the main ...

Our microstructural analysis of the studied alloys has shown that barium introduction leads to the formation of a more homogeneous structure of grains and to an increase in their size (Figure 2), ...

Abstract The procedures for design and reinforcement projects regarding flexible pavements available in Brazil are mostly based on empirical models developed from studies carried out in specific ...
