Restoring and maintaining the gas layer (plastron) on underwater superhydrophobic surface (SHS) is critical for the real-world application of SHS, such as reducing friction drag in high-Reynolds number turbulent flows. In this work, we experimentally investigated the capability of a technology based on porous material and gas injection to restore the plastron on an underwater SHS from a fully wetted state.
We tracked 3D motion of bacteria and found how they accumulated to the wall. Check out more information here.
Md Elius worked in Ling’s lab from Sep 2021 to Aug 2023. His Master thesis work was to understand the bacterial and super-hydrophobic surface interaction. He will join UC Berkeley as a graduate student. Congratulations!
A new paper entitled “Fabrication and characterization of super-hydrophobic surfaces based on sandpapers and nano-particle coatings” was published in Colloids and Surfaces A: Physicochemical and Engineering Aspects. This work was supported by NSF, ONR, and UMassD seed fund. Full article is available here.
Christina Hart and her team members Ethan Osley, Damian Guilbe Boscana, and Shawn Marcoux took home the first-place $500 prize for their design to build an underwater holographic imaging system for marine microplastics detection. This is a capstone project, sponsored our group. Check out more details of this news here.
We have a new paper accepted for publication at Physical Biology, entitled: “Velocity correlations in jackdaw flocks in different ecological contexts”. This work is a collaboration with Prof. Ouellette from Stanford University and Prof. Thornton from University of Exeter. The plot below show the spatial distributions of velocity and velocity fluctuation in one of the jackdaw flocks.
A new paper entitled “Effect of hologram plane location on 3D particle tracking using digital holographic microscopy” was accepted for publication in Applied Optics. This work was supported by ONR.
A new paper titled: “A General Model for the Longevity of Super-Hydrophobic Surfaces in Under-Saturated, Stationary Liquid” was published in Journal of Heat Transfer. This work is supported by ONR and NSF.
