简介:Abstract 

Surface attached nanobubbles have not only been a challenge to understand their diffusional stability but even more they challenged the experimentalist to prove their existence reliably. A multimodal optical atomic force microscopy approach provided data to measure size and content of these soft objects. I will try to convince you that hydrophobic attraction and pinning is sufficient for the understanding of all reliable experimental data. 

报告人介绍:Brief Biography 

Claus-Dieter Ohl (PhD Physics, U G?ttingen, 1998) works experimentally on fundamental and applied fluid mechanics. He is interested in fast multiphase flows such as laser induced cavitation, sonoluminescence, shock waves in liquids and their medical applications, droplet fragmentation and recently a novel boiling regime. After a two postdoc positions at Johns Hopkins (Prof Prosperetti) and U Twente (Prof Lohse) he received the Dutch VIDI fellowship 2005 to focus on application of cavitation for drug delivery. In 2007 he joined Nanyang Technological University in Singapore and was tenured in 2012. During the 10 years at NTU his lab made important contributions to cavitation in microfluidics and soft materials, time-reversal acoustics, focused photoacoustics, and nanofluidics. In 2017 he was appointed as full Professor at the University of Magdeburg in Germany and is now setting up their Soft Matter department. In his spare time he explores how to make use of virtual reality for education.
