Roll-to-roll (R2R) technologies are mature core processes in manufacturing lines for graphical printing industry. In several other areas (e.g. electronics or optics) R2R techniques are emerging, being expected to notably lower the unit prices of flexible devices. In particular, recently developed roller-based nanoimprinting methods enable unrivalled throughput and productivity for precise fabricat ...

The main objective of Riblet4Wind is the transfer of a technology that has already demonstrated its capacity for increasing the energy efficiency in the aeronautics sector, to the wind energy industry.Application of functional coatings with riblet structure will improve the drag to lift ratio of rotor blades significantly. Wind tunnel experiments have proven the capability of this riblet-coating t ...
