Asymptotics for Orthogonal Polynomials and High-frequency Scattering Problems KU Leuven
The goal of this thesis is to exploit asymptotic behaviour in high-degree orthogonal polynomials and high-frequency acoustic scattering problems to obtain %[Dave] problems. This leads to
a lower computational cost. The code is made publicly available and validates this goal as well as the accuracy of the results of this thesis.
We are interested in the higher-order asymptotic behavior of orthogonal polynomials of Jacobi-, ...
Advanced illumination techniques for high-contrast highresolution fluorescence and scattering microscopy Ghent University
In light microscopy an object is illuminated with a lamp or a laser and the transmitted,
reflected or fluorescent light is detected to get information on the object. In the project two approaches will be developed to study small particles and their interaction with living cells: Light Sheet Fluorescence Microscopy and Complex Beam Scattering Microscopy.
In standard fluorescence microscopy the entire sample is illuminated and there ...
Supramolecular organization of conjugated polythiophenes studied by harmonic light scattering KU Leuven
Crystallization is a very common process in nature and has important applications in many scientific domains. The crystal structure determines physical and chemical material properties. It is easy and well known how to characterize crystal structures. However to gain control over the crystals structure and the properties (i.e. crystal engineering), one must control the crystallization process. To do so, fundamental understanding of ...
In-situ study of the crystallization dynamics of organic materials with harmonic light scattering. KU Leuven
We propose to study the crystallization dynamics of organic materials using harmonic light scattering. Harmonic light scattering is a combination of second-harmonic and third-harmonic light scattering, two nonlinear optical processes, that yield information on growth and symmetry of all intermediates during the crystallization process. Currently, no other accessible techniques are available to obtain this type of in-situ information. A first ...
Studying self-assembly of cellulose nanocrystals with harmonic light scattering KU Leuven
The aim of this project is to study the self-assembly and phase behavior of liquid crystalline cellulose mesophases with advanced light scattering techniques. These techniques use harmonic light scattering, whereby very intense laser light generates so-called harmonics. For example, laser light of 900 nm will generate new wavelengths at 450 nm (second harmonic) and 300 nm (third harmonic). These harmonics enable us to characterize the local ...
Quantification of 3D correlated disorder in materials from electron diffraction diffuse scattering with application to lithium battery materials. University of Antwerp
The first aim of this project is to determine whether it is possible to quantify the three dimensional correlated disorder in materials using the three dimensional diffuse scattering in electron diffraction patterns. Correlated disorder is any type of deviation from an average structure that is correlated between neighbouring unit cells only. Many open questions in materials science are related to this correlated disorder. If we can use electron ...
X-ray scattering to study nanostructures of solids and food Ghent University
Everything that surround us is made out of building blocks. Their configuration and the manner in which they connect to each other determines the characteristics of a system (material or food). For instance, it determines their color, hardness, melting point, performance and stability. The length scale of these building blocks is in the nanoscale and can be studied by X-ray scattering. Scattering techniques are non-invasive; therefore, the ...
Study of nucleation and crystal growth of pharmaceuticals by X-ray and harmonic light scattering Ghent University
In this project we will study the crystallization process of pharmaceutical compounds using state-ofthe-
art nonlinear optical scattering techniques, combined with more traditional linear scattering and
x-ray scattering techniques. The proposed techniques provide complementary information about
different stages of the process, from aggregation and nucleation to subsequent growth. This opens a
window into the fundamental ...
