Industrial applications often contact for surfaces made to attract or repel h2o. EU-funded researchers are devising new strategies to characterise and manufacture such surfaces and will make their findings general public in a new Open Innovation Ecosystem.

The leaf of the lotus flower is famed for its potential to shed h2o and retain itself clear and dry. Can we find out from biology and style elements with very similar houses? That is the goal of the fourteen educational and industrial partners in the EU-funded OYSTER venture who are discovering the ‘wettability’ of surfaces and how they can be engineered to purchase.

‘Most elements are both in call with the environment or with h2o or other liquids,’ states venture coordinator Marco Sebastiani, from the College of Roma Tre in Italy. ‘So, you may possibly want to regulate how the h2o interacts with all those surfaces.’ A floor that repels h2o, like the lotus leaf, is reported to be hydrophobic. A floor that draws in h2o is hydrophilic.

The impetus driving the venture arrived from field. One business was trying to find new hydrophilic elements for tender call lenses whilst yet another wished to make hydrophobic plane home windows that shed h2o and are self-cleansing. ‘These were two totally diverse applications but the scientific difficulty was the identical: to start with of all, how to regulate the wettability by engineering the surfaces and then how to evaluate the wettability.’

Triangular tactic

OYSTER is primarily based on what Sebastiani calls a ‘triangle’ of 3 pillars: characterisation, producing and modelling. 1st, the venture is working with the European Materials Characterisation Council to style normal strategies for measuring and characterising the wettability houses of surfaces.

Then researchers will use innovative producing and coating technologies to make surfaces of specified wettability. ‘We also want to develop products that can forecast what the wettability will be by shifting the chemistry or morphology of the floor. So, we are working on these 3 most important pillars and making an attempt to bring these innovative applications to actual industrial products.’

Now at the midway position of the 4-yr venture, the researchers will shortly complete a series of protocols for measuring wettability and other floor houses. ‘We are currently screening samples from the industrial partners,’ Sebastiani states. ‘Next we will use the protocols to style and make new elements with managed wettability.’

Open innovation

Although the project’s fast goal is to create methods for the health care and aeronautics sectors, yet another aim is for OYSTER to direct the way in generating what is recognized as an Open Innovation Ecosystem, a internet platform where researchers and corporations can share strategies.

‘The outcomes of the venture will not be limited to the two most important applications and the corporations included,’ Sebastiani clarifies. ‘We will share the facts and the know-how that we will create during the venture. Then we will be in a position to locate other corporations, other SMEs in specific, that may possibly be fascinated in these applications.’

Applications could be in any industry where a reliable floor interacts with a liquid. Sebastiani thinks the most significant will be prosthetic implants such as knee and hip joints, intended to bond with the bordering tissue. ‘If you can regulate the wettability you can regulate pretty finely how the cells increase on these surfaces.’

Sebastiani hosted an open up day in Brussels on 28 November to showcase OYSTER and associated tasks and, most importantly, to boost the Open Innovation Ecosystem for field as a complete. ‘In potential, there will be parts for any form of industrial difficulty,’ he states. ‘This could be an engine for fixing problems coming from field in a significantly a lot quicker, much more efficient way.’
