The 4^th BioApproNFS-Wett Workshop was held at Instituto Superior Técnico, in Lisbon, Portugal, on the 4^th and 5^th June, 2015.

The workshop, hosted by the Multiscale Transport Phenomena Laboratory of IN+ was organized in the context of the network of the Marie-Curie project “BioApproNFS-Wett - Biomimetic Approaches of Natural Functional Surfaces with hierarchical micro & nano structure and the extreme Wettability”.

Invited speakers from the University of Nottingham, Liverpool John Moores University, Instituto Superior Técnico and from the Key Laboratory of the Ministry of Education for Bionic Engineering, at Jilin University, gave in total 10 lectures divided in three main sessions: Session I - Micro-structured & bioinspired surfaces for extreme wetting scenarios:  Manufacturing; Session II - Micro-structured & bioinspired surfaces for extreme wetting scenarios: Applications; Session III – Bionics and Biomimetics in Engineering.

The workshop ended on the 5^th June, after a visit to the Laboratory of Thermofluids Combustion and Energy Systems of IN+ and particularly to the Multiscale Transport Phenomena Laboratory, where the workshop participants were able to see the various experiments and equipment working in situ and discuss with the researchers working at the lab in a more informal environment.
