The ancient Egyptians poured water over sand to reduce solid-solid friction when transporting heavy blocks of stone across the desert. More recently, the same basic idea—turning surfaces slippery when wet—was used to minimize and even eliminate solid-liquid friction, resulting in new classes of ultra-slippery, liquid-repellent surfaces. I will discuss different strategies to design such surfaces inspired by examples in nature, namely the pitcher plant and articular cartilage. Such surfaces can eliminate contact-line pinning on moving droplets (water and oil) and have many applications in the water-energy nexus (water-harvesting, anti-icing, and anti-fouling), biomedical devices (preventing blood clots), and making photonic crystals.Event details:<ul><li>Wednesday 19 October</li><li>10:30am - 11:30am (AEDT), followed by a catered light lunch</li><li>In person only</li><li>S﻿eminar Room 4001, Level 4, Sydney Nanoscience Hub (Building A31), Physics Road, The University of Sydney</li><li><a href="https://maps.sydney.edu.au/?area=CAMDAR&amp;_ga=2.165129786.462042188.1606200107-789368931.1586843718" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">see map</a> (walk up the big grey stairs or take the lift to Level 4 from the first entrance on left in the courtyard between Physics and SNH)</li></ul>Please be sure to RSVP to the event by 18 October.About the speaker:<a href="https://www.dandaniel.me/" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">Dr Dan Daniel</a> was born in Indonesia, but spent most of his formative years outside: first in Singapore, followed by undergraduate and postgraduate training in the UK (Cambridge, 2011) and the States (Harvard, 2017), before finally returning to Singapore. He is now a group leader (<a href="https://www.a-star.edu.sg/imre/research-departments/advanced-characterization-and-instrumentation/the-droplet-lab" target="_blank" data-msys-clicktrack="0" rel="nofollow noopener noreferrer">the Droplet Lab</a>) at the Agency for Science, Research and Technology (A*STAR), Singapore. His main research interests are in the physics of droplets, wetting/adhesion, and soft matter. He has authored and co-authored multiple papers in top journals, including Nature Physics, Nature Materials, PNAS, PRL, and PRX. More recently, he was awarded the IACIS Emerging Investigator Award (2022). He will be moving his lab to KAUST (Saudi Arabia) in Nov 2022.Image below: Dr Dan Daniel
