Non equilibrium thermodynamics of protein organization

Three quarters of the thesis will be devoted to the discussion of non equilibrium systems. We show how certain biological systems cannot be described by standard thermodynamics. The reason is that the energy consumption due to the hydrolysis of ATP imposes ...

Unravelling the precipitation pathway of biorelevant minerals: from fundamental studies to biomedical applications

Agnese Carino

The formation pathway of biominerals archetypes, namely calcium carbonate (CaC) and calcium phosphates (CaPs), was investigated using a multidisciplinary approach. The time-resolved analytical data were collected using a controlled-composition method and i ...

Coupled Thermo-hydro-Mechanical Effects on Caprock Stability During Carbon Dioxide Injection

Lyesse Laloui, Chao Li

This study presents a numerical investigation of the effects of coupled material properties on the caprock stability. A thermo-hydro-mechanical framework is proposed in order to reproduce the physical processes. The results indicate that for a given geomet ...

Study of Silicon Nitride resonators for optomechanics and security applications

Tom Larsen, Alberto Barulli

In this work the design, fabrication and characterization of silicon nitride nano-mechanical resonators is presented, starting from silicon nitride thin films deposited on Si wafers according to ten different recipes. The properties of such devices will de ...

Watching ultrafast responses of structure and magnetism in condensed matter with momentum-resolved probes

Fabrizio Carbone, Paul Beaud

We present a non-comprehensive review of some representative experimental studies in crystalline condensed matter systems where the effects of intense ultrashort light pulses are probed using x-ray diffraction and photoelectron spectroscopy. On an ultrafas ...

New method for measuring compressibility and poroelasticity coefficients in porous and permeable rocks

Lucas Xan Pimienta

Over the last decades, a large understanding has been gained on the elastic properties of rocks. Rocks are, however, porous materials, which properties depend on both response of the bulk material and of the pores. Because in that case both the applied ext ...

2D meso-scale modeling of masonry elements using cohesive elements

Jean-François Molinari, Katrin Beyer, Nicolas Richart, Shenghan Zhang, Seyedeh Mohadeseh Taheri Mousavi

Many stone masonry structures that were constructed in the past centuries are now counted towards the cultural heritage. The low strength and brittle behavior make these heterogeneous structures very vulnerable to various natural or man-made disasters such ...

Predicting the axial capacity of piles in sand

Lyesse Laloui, Jean-Marie Fuerbringer, Alessandro Francesco Rotta Loria, Alberto Minardi, Luis Felipe Orellana Espinoza

Currently, although several tools have been proposed for the numerical modelling of the pile-soil interface, there is not a well-established framework concerning the quantitative impact that different estimations of the mechanical properties of this settin ...

Picosecond acoustics method for measuring the thermodynamical properties of solids and liquids at high pressure and high temperature

Livia Eleonora Bove Kado

Based on the original combination of picosecond acoustics and diamond anvils cell, recent improvements to accurately measure hypersonic sound velocities of liquids and solids under extreme conditions are described. To illustrate the capability of this tech ...

Equation of state of liquid mercury to 520 K and 7 GPa from acoustic velocity measurements

Livia Eleonora Bove Kado

Ultrafast acoustics measurements on liquid mercury have been performed at high pressure and temperature in a diamond anvil cell using picosecond acoustic interferometry. We extract the density of mercury from adiabatic sound velocities using a numerical it ...
