Modification of the morphology and functional properties of metallic surfaces with low-energy ion beams. KU Leuven
Proteins, e.g. antibodies or enzymes, are highly attractive molecules for both
research and application due to their specific properties and functionalities. A
vast majority of the applications involve immobilized molecules, i.e. proteins
which are attached to a solid substrate. Ideally, an accurate control over the
amount, position and orientation of the immobilized biomolecules is required,
as the functionality of ...
Quoting Nobel Laureate Wolfgang Pauli: “God made the
bulk; surfaces were invented by the devil”. Surfaces and
interfaces are indeed prone to unpredictable physical and
chemical modifications due to interactions with
uncontrolled atmospheres, surface re-organization, and
contamination. High-impact research dealing with
interfaces can therefore only be achieved if surfaces can be
prepared, treated, and ...
Molecular self-assembly has been widely used as tool for the modification and functionalization of surfaces, whereby in many cases pristine surfaces like highly-oriented pyrolytic graphite (HOPG) were used as substrates to study supramolecular self-assembly from solution. Scanning probe techniques enable the study of these molecular layers with sub-molecular resolution. Similar to crystallization in bulk, supramolecular self-assembly is known ...
Surfaces and interfaces play a pivotal role in chemistry and physics, because they break phase symmetry. Often ordering effects occur near the surface, which deeply modify the physical properties and chemical reactivity. Thermodynamically, liquid crystals are rather simple systems because their liquid character allows them to relax rapidly and reach equilibrium. A far more complex and richer situation occurs for crystals, for which the ...
The IOF fellow will focus on membranes and functional surfaces, two areas linked by the need for expertise in thin film deposition. Three research groups form the scientific foundations for this application. They focus on membrane development (Ivo Vankelecom, COK, Partner 1), porous coatings for sensors and diagnostics (Rob Ameloot, COK, Partner 2) and biomedical implants and devices (Bob Puers, ESAT, Partner 3).
Carbon-based materials form the backbone of many industrial applications such as chemical purification, separation technology and, gas adsorption and storage. The applicability of most of these materials, which are composed of two-dimensional (2D) sheets of sp2 hybridized carbon called graphene, is a result of their porosity and high surface area. A large variety of these come from natural sources and/or are produced in such a way that their ...
