It is worldwide recognized that the superior properties of nanomaterials will promise a revolutionary new approach with a major impact in various innovative applications. These property improvements or even new properties derive from structural features such as particle size or layer thickness on a scale 1-100 nm, much smaller than that found in conventional materials. The screening and synthesis of new nanostructured metal oxides is a major research topic of the Institute for Materials Research (IMO). The research is performed in close collaboration with IMOMEC, the division of IMEC located at the Campus of Hasselt University. The responsible scientists within IMO/IMOMEC are prof. dr. Marlies Van Bael and prof. dr. Heidi Van den Rul. The main scientific interest of the research group lays in the development of environ- mentally friendly chemical syntheses of ce- ramic oxide thin films, ceramic oxide pow- ders and (nano)particles. The research is focused on solution based synthesis of nanostructured metal oxides: • nanoparticles with controlled shape and size, • thin films (<100 nm), ultrathin films (<30nm) and • nanostructured films with various compo- sitions and properties.

The main scientific interest of the research group lays in the development of environ-mentally friendly chemical syntheses of ce-ramic oxide thin films, ceramic oxide pow-ders and (nano)particles.
The research is focused on solution based synthesis of nanostructured metal oxides: • nanoparticles with controlled shape and
size, • thin films (<100 nm), ultrathin films
(<30nm) and • nanostructured films with various compo-
sitions and properties.
Film deposition starting from a water-based precursor solution is a non-toxic, environ-mentally friendly process to obtain coa-tings with tailored properties such as bio-compatibility or bioactivity, UV-protection, antibacterial or catalytic properties etc.

Hasselt University – Campus DiepenbeekAgoralaan - Building D – B- 3590 Diepenbeek (Belgium)
Hasselt University, campus Diepenbeek, is located in the center of the Euregion-Maas-Rhine. A shortdistance from Liège, Maastricht, Eindhoven, Leuven, Brussels, Antwerp, Aachen, and Cologne.
Since nanomaterials possess unique, be-neficial, chemical, physical and mechani-cal properties, they can be used for a wide variety of applications. For (multi)metal oxide nanomaterials, these include e.g.- tougher and harder but also ductile and
machinable ceramics - membranes for gasfiltration and nano-
filtration - high sensitivity sensors - high performance electronics - next generation computer chips - nanoparticulate catalysts - components with an increased fatigue
life - longer-lasting medical implants
These are only a few applications of (mul-ti)metal oxide nanomaterials; many other uses are yet to be discovered.
A major barrier at this moment is the abi-lity to synthesize nanoparticles and films with precisely controlled size, composi-tion and shape in a way that is econo-mically and ecologically well-considered. Therefore,processing of the nanoscale building blocks into the real materials suitable for applications is of essential importance in view of revealing the high performance and new properties.
