SIAM Platform (University of Namur) expertise in materials characterization relies on its capacity to use and combine various spectroscopies (XPS, ToF-SIMS & IBA). SIAM has several facilities for functionalizing materials and/or synthesizing thin films by plasma treatments and performs fundamental research in materials sciences, surfaces, interfaces and ion/matter interaction. Different kinds of materials and/or samples, coming from materials sciences, life sciences but not only (materials evaluation inside a biological matrix) can be thoroughly analysed.
