Retention behaviour of natural clayey materials at different temperatures

Lyesse Laloui, Simon Salager, Marta Rizzi

The water retention capacity of geomaterials, and especially clayey soils, is sensitive to temperature changes as the physical mechanisms of retention, such as capillarity or adsorption, are affected by it. It is therefore a major issue to be able to defin ...

The hydro-mechanical behaviour of shales is becoming one of the most important issues in modern geomechanics, largely driven by petroleum industries (i.e., the extraction of shale gas), the sequestration of CO2 and the nuclear waste geological storage. In ...

Pd-functionalized MEMS resonator for hydrogen gas sensing

Jürgen Brugger, Luis Guillermo Villanueva Torrijo, Thomas Kiefer, Jonas Gustav Henriksson

This work presents the fabrication and characterization of a novel hydrogen-detecting micro-resonator based on the expansion of palladium (Pd) as it is exposed to hydrogen (H2) gas. The working principle of the device has been confirmed and it shows a stro ...
