GCN-Seminar, Maria Messing, NanoLund - Designing Nanoparticle-based Materials: From Sparks to Multifunctional Materials
Smart nanomaterials with designed properties based on nanoparticles have the potential to revolutionize applications in, for example, magnetics and catalysis. But implementing nanoparticles’ potential for such applications requires realizing and understanding nanoparticles with controllable size, morphology, crystal structure and chemical composition on a large scale, at low costs and in a safe and environmentally friendly way.
Spark ablation is a method with high potential to fulfill the above declared requirements, especially for the production of pure metal and compound particles . In this talk I aim to demonstrate some of the possibilities with aerosol-based nanotechnology. I will show how spark ablation can be used to produce nanoparticles with fully precise and tailored size, morphology and chemical composition [2, 3], and their controlled self-assembly into larger structures . I will then show a few examples of the possible use of these particles in magnetic and catalytic applications.
