The leaf of the lotus flower is famed for its potential to drop drinking water and preserve itself thoroughly clean and dry. Can we learn from biology and structure resources with similar qualities? That is the aim of the fourteen academic and industrial companions in the EU-funded OYSTER venture who are checking out the wettability of surfaces and how they can be engineered to purchase.

Most resources are possibly in get in touch with with the atmosphere or with drinking water or other liquids, suggests venture coordinator Marco Sebastiani, from the University of Roma Tre in Italy. So, you could want to control how the drinking water interacts with these surfaces. A floor that repels drinking water, like the lotus leaf, is said to be hydrophobic. A floor that draws in drinking water is hydrophilic.

The impetus guiding the venture arrived from sector. A single enterprise was searching for new hydrophilic resources for smooth get in touch with lenses though a different wanted to make hydrophobic aircraft windows that drop drinking water and are self-cleansing. These ended up two totally different programs but the scientific challenge was the identical: very first of all, how to control the wettability by engineering the surfaces and then how to evaluate the wettability.

Triangular approach

OYSTER is based on what Sebastiani calls a triangle of 3 pillars: characterisation, production and modelling. To start with, the venture is working with the European Elements Characterisation Council to structure normal approaches for measuring and characterising the wettability qualities of surfaces.

Then researchers will use superior production and coating technologies to make surfaces of specified wettability. We also want to develop styles that can forecast what the wettability will be by transforming the chemistry or morphology of the floor. So, we are working on these 3 principal pillars and attempting to bring these superior programs to actual industrial items.

Now at the midway issue of the 4-12 months venture, the researchers will shortly finish a sequence of protocols for measuring wettability and other floor qualities. We are previously testing samples from the industrial companions, Sebastiani suggests. Next we will use the protocols to structure and make new resources with managed wettability.

Open up innovation

Though the projects quick aim is to deliver methods for the health care and aeronautics sectors, a different aim is for OYSTER to lead the way in making what is known as an Open up Innovation Atmosphere, a internet platform where researchers and companies can share thoughts.

The outcomes of the venture will not be restricted to the two principal programs and the companies involved, Sebastiani explains. We will share the information and the know-how that we will deliver in the course of the venture. Then we will be capable to obtain other companies, other SMEs in individual, that could be fascinated in these programs.

Apps could be in any discipline where a sound floor interacts with a liquid. Sebastiani thinks the most crucial will be prosthetic implants these types of as knee and hip joints, supposed to bond with the encompassing tissue. If you can control the wettability you can control pretty finely how the cells develop on these surfaces.

Sebastiani hosted an open up day in Brussels on 28 November to showcase OYSTER and linked initiatives and, most importantly, to advertise the Open up Innovation Atmosphere for sector as a complete. In long term, there will be locations for any form of industrial challenge, he suggests. This could be an motor for solving issues coming from sector in a considerably quicker, far more helpful way.
