Chiral Symmetry Breaking: Crystallisation of Molecules at Surfaces Chiral symmetry breaking of molecular crystals is a spontaneous process which separates molecules into their enantiomorph state so that they can form individual chiral crystal structures. The talk will introduce important terms which are related to chirality of molecules. Two dif ... more |

Influence of pore-confined water on the thermal expansion of a zinc-based metal-organic framework Metal-organic frameworks (MOFs) consist of metal nodes that are connected through organic linkers forming a porous network. While certain MOFs may collapse upon minimal water uptake, others possess remarkable stability upon water exposure allowing to harvest water from atmospheri ... more |

Physically based mean-field modelling of dislocation creep On a macrosopic scale, the phenomenon of "creep" is the slow plastic deformation of a solid material at high temperatures and mechanical stress. In the natural environment, creep is the main mechanism of deformation in the earth's solid crust at a dept greater than 20 km. In tech ... more |

Analysing transport through porous media with pore network modeling When simulating Stokes flow, characteristic values are used to describe the air transport properties through porous media, such as paper. However, the arrangement of the pathways is often not adequately represented in the definition of these properties. In this study, we highligh ... more |
