Development and application of an innovative method for studying the diffusion of dissolved gases in porous saturated media KU Leuven
Fine-grained sedimentary formations are investigated in numerous scientific fields, e.g., as
a host formation for a deep geological repository for high-level radioactive waste, as cap rocks for oil reservoirs or CO2 geosequestration, or as potential economic resources in case of shale gas extraction. The permeability characteristics of these geological strata are important to assess their
ability to act as a long-term effective ...
A general law describing the diffusion of membrane proteins in vivo based on single molecule tracking of membrane proteins in Escherichia Coli. KU Leuven
The ultimate goal of cell biology is to understand how proteins function in real cells and to understand their regulatory mechanisms. To achieve this goal one needs to analyze molecules in their cellular environment and not under idealized test tube conditions. A major difference between in vivo and in vitro conditions is the crowdedness (and associated molecular complexity) of the cytoplasm and biological membranes. As a consequence ...
Multivariate Decomposition Finite Element Method for Elliptic PDEs with Random Diffusion Coefficients KU Leuven
We develop a multivariate decomposition finite element method (MDFEM) for solving elliptic PDEs with random diffusion coefficients where the diffusion coefficient is parameterized by a countably infinite number of random variables and an appropriate system of functions. We consider two models of parametric diffusion coefficients: uniform and lognormal.
We show that the MDFEM reduces the computational complexity of estimating the expected ...
Accounting for Complex Structure in Diffusion Weighted Imaging Data using Volume Fraction Representations KU Leuven
The domain of diffusion weighted imaging (DWI) has come a long way since its initial development in the mid-1980s. Over the years, we have gained a better understanding of the accompanying techniques and necessary processing steps involved, furthermore leading to a wealth of new insights in the complex workings of the (human) brain. The introduction of diffusion tensor imaging (DTI) has played a crucial role in thisprocess, as it provided ...

Modeling of diffusion and reaction kinetics in nanoporous materials. Ghent University
My project is situated in the field of porous materials. These condensed state materials require a multi-scale approach, because processes occur on a range of time and length scales: from quantum pgysics/chemistry at the atomistic scale up to diffusion at the nanoscale. This project will study the materials with computer experiments, in order to use the new chemical/physical insights about diffusion, adsorption and kinetics for the ...
