Low-cost nanostructures
Why nanostructures ? Why/what is low-cost ?
- IMM Our low-cost NS
- IMM ZnO low-cost NS
Nanorods applications -Light diffuser (IMEC, Belgium) -UV detectors (Catania) -Catalysis (KU Leuven, Belgium)
Nanowalls applications: -pH e gas sensor (Roma) -Cancer detection (Tel Aviv Univ.) -DSSC (Tunisie)
200 nm Al film
ZnO nanowalls
Other applications: Energy harvesting Wearable electronics Disposable portable devices Flexibile, ink-jet fabrication
