Neto, Chiara - University of Sydney

研究领域

Associate Professor Chiara Neto’s research on the physical chemistry of interfaces takes inspiration from nature, seeking ways to replicate natural phenomena to apply to such diverse challenges as developing self-cleaning paints, increasing the energy efficiency of commercial shipping and alleviating water scarcity in arid climates. “I am fascinated with natural patterns and surfaces, their functionality and beauty, and how they can be mimicked to develop functional materials that everyone can experience in everyday life. “One area of my research involves working with superhydrophobic (extremely water-repellent) surfaces that mimic the way a lotus leaf repels water. Water rolls rather than slides off a lotus leaf, taking with it any dust particles and keeping the leaf dry and clean. Such self-cleaning coatings would have many applications, from the paint to the automotive to the food industries. “Another area of interest is the investigation of fluid flow against solid surfaces. By finely controlling the chemistry and topography of surfaces, we are able to induce ‘interfacial slip’, thus reducing hydrodynamic drag. This technology could be applied to coating a ship’s hull to enable it to move more quickly through water, reducing energy input and pollution. “I am also working to develop functional micro-patterned surfaces, such as one that mimics the African desert-dwelling Stenocara beetle, which harvests water from fog. Their mostly waxy shells are micro-patterned with special patches where water condensation can occur, and as this condensation grows, the drops of water run along channels into the beetle’s mouth. From this example I hope to develop a low-cost surface coating that can be used to capture atmospheric water from humid air, to alleviate water scarcity in arid places or in emergency situations. “I love my job. I cannot imagine doing anything that interests and challenges me more. “I joined the University of Sydney in 2007, and I find it stimulating and extremely rewarding. I am surrounded by people who are ambitious but also collegial and collaborative, who take great pride in their research but also in their service to the community and to their students. Sydney Uni has brought out the best skills and attitude I had to offer.”
