From 2D to 3D crystals: a multi-scale, multi-technique and multisystem approach of the crystallization of organic molecules (2Dto3D). University of Antwerp
The occurrence of two or more crystal structures for a given molecule, a phenomenon which is called polymorphism, is ubiquitous to various classes of synthetic and natural compounds. Examples of polymorphism are known in numerous application fields, such as food, explosives, pigments, semiconductors, fertilizers, and pharmaceutical drugs. Different crystal structures, so-called polymorphs, of the same compound exhibit sometimes very different ...
A generalised method for the screening and selection of noncentrosymmetriccrystals for performant NLO-materials. University of Antwerp
Organic second-order nonlinear optical (NLO) materials for electro-optical applications are gaining interest because of their superior properties in comparison with their inorganic counterparts. The design and selection of the materials, however, remains a mainly empirical undertaking due to the multi-level nature of this research. Therefore, in this project, both the molecular and supramolecular levels will be optimised for a promising category ...
Characterisation and modeling of the initial growth and stability of anisotropic Au and Au/Ag nanoparticles at the atomic scale. University of Antwerp
Electron microscopy for materials research (EMAT), Plasma, laser ablation and surface modeling - Antwerp (PLASMANT)
The overall goal of this project is to characterise and simulate the growth and stability of anisotropic Au and Au/Ag nanocrystals at the atomic scale. In order to reach this final objective, our intermediate technical goals are:• To experimentally determine the p osition and chemical nature of each individual atom in anisotropic Au and Au/Ag NP's.• To develop a reactive force field required for the atomistic simulations.
RADESOL - RAtional DEsign of blends for bulk heterojunction SOLar cells Vrije Universiteit Brussel
Dirk Vanderzande, Bruno Van Mele
The main goal of the project is to unravel nanomorphology formation at the molecular level and its effect on device performance beyond the state-of-the-art by an integrated experimental effort and a unique combination of equipment and expertises, aiming at the study of blends via advanced thermal analysis, solid-state NMR, and X-ray diffraction and ptychography 3D imaging techniques, combined with analysis of the optoelectronic characteristics ...
Modeling of the electrical conductivity of thin film solid oxides Vrije Universiteit Brussel
On the physiochemical properties of the interface between nanometer thin polymer films and nano-controlled oxide layers Vrije Universiteit Brussel
This project will focus on nanometer thin polymer films on oxides as representing the ideal hybrid system to understand the interface between network polymers and oxide substrates. In order to unravel the interactions going on in this area, we will analyse them in a very controlled way by tuning both the characteristics if the oxide layers as well of the polymer film.

Development of dynamic preventive self-healing thin films based on reversible covalent networks Vrije Universiteit Brussel
Filip Du Prez, Guy Van Assche
Thin cross-linked polymer films with multiple reversible covalent bonds are developed as a sustainable self-restoring alternative for regular surface coatings prone to fatigue- and micro damage. In this project, novel photo-reversible covalent linking units will be synthesized that can be split and reformed multiple times by different wavelengths of light without appreciable degradation. An innovative network-design will guarantee that small ...
