内容简介:

Icing has long been recognized as a serious hazard for safety and for functioning of systems in diverse areas such as transportation, power and communication systems, infrastructures, and even domestic or commercial appliances. The control of water behavior at the interface through the tailoring of surface wetting properties represents a great scientific and technological challenge and opportunity, which can be used as a strategy to control and mitigate ice formation on surfaces. During the lecture, Dr. Antonini will present his research activities focused on understanding the interaction mechanism between liquid and solid surfaces in freezing conditions. Focus will be given to the effects of surface wetting and topography on ice nucleation, to the wetting behavior of superhydrophobic surfaces in icing conditions, and to ice adhesion, highlighting the role of environmental conditions where relevant. A brief discussion of practical issues, challenges, and innovations in using non-wetting coatings will also presented.

主讲人简介:

Dr. Carlo Antonini received the BSc in Aerospace Engineering (2004) and the MSc in Aeronautical Engineering (2007), from Politecnico di Milano, Italy, and the PhD in Technologies for Energy and Environment from University of Bergamo (2011), Italy, with a thesis titled “Superhydrophobicity as a strategy against icing”. In 2012, he received support from the European Research Council (ERC) to join ETH Zurich, Switzerland, as a Marie Curie Fellow; and worked in the Laboratory of Thermodynamics in Emerging Technologies on the project “ICE2: ICEphobicity for severe ICing Environments”. In March 2015 he joined EMPA – Swiss Federal Laboratory for Material Science and Technology – as scientist, focusing on the control of surface wetting properties of cellulose-based materials for various engineering applications, ranging from liquid separation (oil remediation) to thermal insulation. One of projects included ice templating as a technique to fabricate ultra-porous foams from nanofibrillated cellulose with selective liquid absorption. Since 2017 he is the scientific advisor of ApiTech (www.api-tech.it), an italian startup supporting innovation in SMEs. In September 2018 he joined the Department of Materials Science at the University of Bicocca-Milano (Italy), as tenure-track senior researcher, with support of a Rita Levi Montalcini Fellowship.
