Breathing behavior of flexible mixed metal Metal- Organic Frameworks

Date: 01.03.2017
  • Promotor(s): Danny Vanpoucke
  • Institution(s): UHasselt
  • Domain(s): Physics
The MIL-47/53 metal organic framework has a wine rack motif. In this motif metal-oxide chains can be considered as hinges, and the linker molecules as the wooden planks linking the hinges. From this picture, it is easy to understand such a metal organic framework to be flexible. However, in experiment it was found that depending on the metal used in the hinges, the wine rack can be very flexible (MIL-53(Al)) or rather rigid (MIL-47(V)). Furthermore, adding V to MIL-53(Al) makes this framework less flexible. In this work, we will investigate, using quantum mechanical calculations, how mixing the metals modifies the flexibility of these metal organic frameworks. We will calculate how we can prevent these wine racks from collapsing.

Atomistic picture of fluorescent probes into lipid bilayer membranes: probing lipid rafts through (non-) linear absorption spectroscopy

Date: 01.07.2016
  • Promotor(s): Stefan Knippenberg
  • Institution(s): UHasselt
  • Domain(s): Life sciences
Cells and their membranes are known to be fundamental building blocks of living organisms and human beings. It is therefore of primordial importance to trace and early detect malfunctions or defects. One of the ideas to gain information about the condition of the cellmembrane is the embedding of a suited fluorescent probe. Dependent on its environment – and on e.g. the orientation of the surrounding lipids – the UV/VIS and non-linear absorption spectra of the compound are expected to change. With the foreseen calculations, we investigate the shape of the bilipid membranes and quantize the influence on the probing species.

Breathing behavior of flexible Metal-Organic Frameworks with MIL-47/53 topology

Date: 01.07.2016
  • Promotor(s): Danny Vanpoucke
  • Institution(s): UHasselt
  • Domain(s): Physics
This project is part of ongoing research studying breathing Metal- Organic Frameworks. These materials are known to change their volume by 50% or more under the influence of temperature, the presence of certain molecules or pressure. This makes them well-suited for applications as sensors (e.g. the material contracts/expands at a certain temperature or in the presence of certain molecules) or shock-absorbers (i.e. the material contracts under pressure and expands again when the pressure is released, without losing its crystal structure). In this project, we investigate the role of the metal-clusters, determining if breathing occurs under the influence of temperature or pressure.
