Info Beasiswa S3: PhD position: "with focus on Sorption induced deformations of nano/microporous materials"
The Chair of Building Physics of ETHZ studies porous materials and their interactions with fluids. We are offering a
PhD position: "with focus on Sorption induced deformations of nano/microporous materials"
Sorption originates at the molecular scale from
the interactions between the atoms/molecules of the solid skeleton and
the molecules of the fluid. This molecular interaction may lead to
sorption-induced deformations. A signature of many disordered materials
is the appearance of hysteresis in the sorption and mechanical process.
Disorder can be modelled by coupling the material consisting of a
distribution of sorption sites and mechanical contacts at different
scales. The physical behavior of these features and their coupling can
be understood using molecular dynamics and micro-mechanical models.
Using upscaling, the coupling between sorption and deformation is
modeled in a continuum manner by a poromechanical approach, taking into
account the underlying solid-fluid interactions.
In this PhD, we develop a coupled poromechanical model for sorption-induced deformation of nano/microporous materials. This poromechanical model is documented from experimental observations and molecular simulation results performed at lower scales. Different microporous materials will be studied: consolidated granular media, cellular materials and composite materials. Hierarchical polymeric materials, like wood, will be studied in more detail with special focus on shape memory effects upon wetting and drying.
