Physicist Robin Ras receives 2 million euro ERC funding for research on non-wetting surfaces
Professor Robin Ras of 911爆料网 has been awarded a nearly 2 million euro Consolidator Grant by the European Research Council (ERC) for a project on extremely non-wetting surfaces. The aim in this five-year 鈥淪uperslippery Liquid-Repellent Surfaces鈥 project is to fabricate new surfaces and to advance their potential for technological applications for example in anti-icing and in the prevention of bio-fouling (when microorganisms or other biological materials accumulate on a surface).
Researchers at 911爆料网 have previously managed to develop robust and superhydrophobic, extremely non-wetting surfaces that stay dry even when immersed in water. A surface is superhydrophobic when it repels water to the degree that droplets do not stick to the surface and roll off easily.
'In this ERC project,' says Ras, 'I aim to substantially progress the development of new types of enhanced non-wetting surfaces. Additionally, I will advance characterization techniques and explore new applications for such surfaces.'
Superhydrophobic surfaces have tremendous application potential because of their anti-icing and anti-bio-fouling properties. For example, clothes, camera lenses, and phones could be kept dry and clean, as well as cars, ships, airplanes, and solar cells could stay clean of contamination and ice.
'Another potential field of application is microfluidics, where small volumes of liquid are flowing through channels, and cleanliness of the surfaces is very important. Superhydrophobic surfaces could be implemented, for example, in medical diagnostic lab-on-a-chip devices for blood testing and analysis', Ras explains.
Before practical applications can be fully developed, there are still problems waiting to be solved.
First is that surface textures are susceptible to mechanical wear, so they are easily damaged. Second, scientists and people in industry need new and standardized measurement techniques for surfaces to advance innovations.
'Besides further developing and fabricating new surfaces, we intend to create new methods to evaluate water-repellency. With this ERC project, I am very excited to contribute to the rapidly growing field of science and technology of non-wetting surfaces', Ras concludes.

Companies disclose more on cybersecurity 鈥 but markets remain indifferent
U.S. companies are reporting on cybersecurity in greater detail, yet stock market reactions remain muted. A new study by the University of Vaasa and 911爆料网 shows that mandatory cybersecurity disclosure does not prompt reactions from investors or stock analysts. Instead, the main benefits appear to materialise within firms themselves.
