Machining of titanium-based materials using the hybrid Mechano-Electrochemical Milling process KU Leuven
This research aims the investigation and development of a novel hybrid machining process, called "Mechano‑Electrochemical Milling" (MECM). The combination of milling and Electrochemical Machining (ECM) can extend the range of machinable materials and increase the performance of ECM. The considered materials in this research are titanium-based because of the typical interaction between ECM and titanium‑based materials. This interaction implies ...
Temperature dependent NIR emitting lanthanide-PMO/silica hybrid materials KU Leuven Universiteit Gent
Two materials - a mesoporous silica (MS) and a periodic mesoporous organosilica (PMO) functionalized with dipyridyl-pyridazine (dppz) units were grafted with near-infrared (NIR) emitting lanthanide (Nd3+, Er3+, Yb3+) complexes in an attempt to obtain hybrid NIR emitting materials. The parent materials: dppz-vSilica and dppz-ePMO were prepared by a hetero Diels-Alder reaction between 3,6-di(2-pyridyl)-1,2,4,5-tetrazine (dptz) and the double bonds ...
Combination of HAADF-STEM and ADF-STEM tomography for coreshell hybrid materials Universiteit Antwerpen
Characterization of coreshell type nanoparticles in 3D by transmission electron microscopy (TEM) can be very challenging. Especially when both heavy and light elements coexist within the same nanostructure, artifacts in the 3D reconstruction are often present. A representative example would be a particle comprising an anisotropic metallic (Au) nanoparticle coated with a (mesoporous) silica shell. To obtain a reliable 3D characterization of such ...
Towards the development of advanced organized hybrid conjugated polymer/nanoparticle materials KU Leuven
This project aims to optimize the efficiency of optical isolators. Optical isolators are devices that allow light to pass in one direction, but block it in the opposite one. This is very similar to an electrical diode, which allows a current to flow in only one direction. Optical isolators are important, for example, if one wants to protect lasers from back reflections, which can disturb the laser's operation. Furthermore, they are a crucial ...
Carbon based materials and hybrid nanostructures investigated by advanced transmission electron microscopy Universiteit Antwerpen
Polymer based hybrid materials for photovoltaic applications: a morphological and electro-optical approach Universiteit Hasselt
In the scope of reducing the cost of the photovoltaic electricity, the polymer based solar cells are considered as a potential alternative to the expensive conventional silicon solar photovoltaic devices. While reducing the production costs, polymer based solar cells have to maintain the stability and efficiency of the silicon based devices. To realize this, it is necessary to understand and improve the currently limiting factors of the polymer ...
Novel hybrid materials for gas sensing applications made of metal-decorated MWCNTs dispersed on nano-particle metal oxides Universiteit Antwerpen
Hybrid porous titania phosphonate networks with different bridging functionalities: Synthesis, characterization, and evaluation as efficient solvent separation materials Interuniversitair Micro-Electronica Centrum vzw Universiteit Antwerpen Universiteit Hasselt
Hybrid titania phosphonate materials can demonstrate a high added value as tailored sorption materials. They combine high chemical stability with great structural versatility, given the wide diversity of functional groups that can be incorporated. Hereto, a fundamental understanding of the synthesis strategies influencing the material performance is required. Therefore three porous TiO2 phosphonate hybrid structures with different functional ...
