Nanomaterials have unique physical, electronic, mechanical, and chemical properties with an enormous potential for applications. This is a consequence of the modified or even entirely new mechanisms, which can occur at such very small size. Scaling and disruptive size effects on properties come into play as the surface- or interface-to-volume ratio increases dramatically. Therefore, nanomaterials have properties that are dominated by surfaces and interfaces. It is our aim to discover new functionalities based on interface-dominated effects, explore them and develop suitable fabrication processes for their technological use.
