  6. STSM’s: 5 (on 11 granted by the action)

  7. Conclusions & Perspectives: • Positive start-up activity • Increase links with other WG’s • Increase utilisation of STSM • Develop and exploit collaborations with other networks/projects: - COST D43: “Colloid and Interface Chemistry for Nanotecnology” (WG 6) - ESA Topical Teams - ESA Research Projects on Emulsions and Foams • Evaluate and build opportunities for applications into EU 7° FP initiatives
