Business The Solution

Wettability – made and measured to order – Information Centre – Research & Innovation

Industrial applications usually call for surfaces built to bring in or repel drinking water. EU-funded scientists are devising new strategies to characterise and manufacture these types of surfaces and will make their conclusions general public in a new Open up Innovation Environment.

The leaf of the lotus flower is famed for its potential to shed drinking water and preserve itself clear and dry. Can we understand from biology and design elements with very similar qualities? That is the goal of the fourteen educational and industrial associates in the EU-funded OYSTER job who are exploring the ‘wettability’ of surfaces and how they can be engineered to buy.

‘Most elements are possibly in get hold of with the environment or with drinking water or other liquids,’ claims job coordinator Marco Sebastiani, from the University of Roma Tre in Italy. ‘So, you might want to regulate how the drinking water interacts with these surfaces.’ A floor that repels drinking water, like the lotus leaf, is stated to be hydrophobic. A floor that attracts drinking water is hydrophilic.

The impetus at the rear of the job came from industry. One corporation was trying to find new hydrophilic elements for comfortable get hold of lenses though a further needed to make hydrophobic aircraft windows that shed drinking water and are self-cleaning. ‘These were being two absolutely various applications but the scientific difficulty was the exact same: first of all, how to regulate the wettability by engineering the surfaces and then how to evaluate the wettability.’

Triangular solution

OYSTER is based on what Sebastiani calls a ‘triangle’ of 3 pillars: characterisation, manufacturing and modelling. Initially, the job is working with the European Supplies Characterisation Council to design typical strategies for measuring and characterising the wettability qualities of surfaces.

Then scientists will use superior manufacturing and coating systems to build surfaces of specified wettability. ‘We also want to build styles that can predict what the wettability will be by switching the chemistry or morphology of the floor. So, we are working on these 3 principal pillars and hoping to bring these superior applications to true industrial merchandise.’

Now at the midway place of the four-year job, the scientists will shortly complete a series of protocols for measuring wettability and other floor qualities. ‘We are presently tests samples from the industrial associates,’ Sebastiani claims. ‘Next we will use the protocols to design and build new elements with managed wettability.’

Open up innovation

Whilst the project’s quick goal is to generate remedies for the healthcare and aeronautics sectors, a further aim is for OYSTER to guide the way in making what is acknowledged as an Open up Innovation Environment, a web platform where scientists and organizations can share thoughts.

‘The outcomes of the job will not be limited to the two principal applications and the organizations included,’ Sebastiani explains. ‘We will share the information and the information that we will generate through the job. Then we will be capable to come across other organizations, other SMEs in distinct, that might be interested in these applications.’

Programs could be in any industry where a sound floor interacts with a liquid. Sebastiani thinks the most vital will be prosthetic implants these types of as knee and hip joints, meant to bond with the encompassing tissue. ‘If you can regulate the wettability you can regulate quite finely how the cells increase on these surfaces.’

Sebastiani hosted an open up working day in Brussels on 28 November to showcase OYSTER and connected jobs and, most importantly, to endorse the Open up Innovation Environment for industry as a full. ‘In potential, there will be regions for any form of industrial difficulty,’ he claims. ‘This could be an engine for resolving problems coming from industry in a a lot more rapidly, additional effective way.’
