Presentation Transcript

  1. Scientific Board The Scientific Board is composed by some of the Tethis co-founder and by two scientists not directly involved in the firm’s activities. • 2 external members: • Prof. Pier Giuseppe Pelicci, Director of the Experimental Oncology Dept., Europena Institue of Oncology, Milano Prof. Massimo Sancrotti, Analytical Division Leader, TASC-INFM National Laboratory, Trieste, Italy • 5 co-founders members: • Prof. Paolo Milani • Dott. Emanuele Barborini • Dott. Paolo Piseri • Dott. Andrea Ridi • Dott. Simone Vinati

  2. Board of Directors The Board of directors is composed by six Tethis co-founders and one delegate from the University of Milano. • Six co-founders members: • Dott. Stefano Morri - President • Dott. Andrea Ridi - CEO • Dott. Mario Zanone Poma • Prof. Paolo Milani • Ing. Giovanbattista Laghezza • Dott. Massimo Gatelli • One delegate from the University of Milano: • - Prof. Gianpiero Sironi

  3. Main features of the technology • Production and deposition of thin films through cluster assembling on metallic, semi-conducting, polymeric and organic substrates • Compatible with traditional thin films deposition techniques, for the production of nano-composite materials • Compatible with microelectronics planar technologies • Parallel production processes with high deposition rate • Production of micro and nanopatterned films with high spatial resolution and aspect ratio

  4. Fields of application • Tethis’ technology provide an high versatility and has a very broad application spectrum, i.e.: • nanostructured sensor arrays for gas sensing, electronic nose, multi-parametric sensors, environmental monitoring • supercapacitors • fuel cells • photo-catalytic devices • lab on a chip for bio-technological applications (proteomics, genomics e post genomics) • bio-compatible materials for tissue engineering

  5. Source Chamber Deposition Chamber Cluster Beam PMCS Nanostructured Thin Film To Vacuum Pump To Vacuum Pump Technology (1) The production technique, called Supersonic Cluster Beams Deposition (SCBD), consists in the assembling of clusters produced in supersonic expansions. The cluster source, called Pulsed Microplasma Cluster Source (PMCS) was designed, developed, and patented by three co-founders of Tethis

  6. Anode Pulsed Valve Nozzle Cathode Technology (2) PMCS principle of operation 1 2 Microplasma formation due to an intense electric discharge Ion sputtering of cathode surface Injection of an inert gas pulse Expansion of the mixture gas-clusters into a supersonic cluster beam Thermalization of the ablated material and cluster aggregation 3 4

  7. Pre-Industrial Deposition Apparatus (1) This apparatus is at the LGM Labs, University of Milano. It can be used by Tethis personnel due to an agreement between Tethis, INFM and the University of Milano

  8. An example: Nanostructured composites materials for electrochemical applications Platinum content: 1% at. Increase of Platinum content Platinum content: 20% at.
