DOI: 10.1002/adma.202203242
Abstract: Fast removal of small water drops from surfaces is a challenging issue in heat transfer, water collection, or anti‐icing. Poly(dimethylsiloxane) (PDMS) brushes show good prospects to reach this goal because of their low adhesion to… read more here.

DOI: 10.1021/acs.chemmater.8b03183
Abstract: Icing of various surfaces is often a result of the collision of supercooled water drops with substrates. Ice formation from supercooled water drops is initiated by nucleation when the size of an ice embryo reaches… read more here.

DOI: 10.1021/acs.langmuir.1c03206
Abstract: Superhydrophobic surfaces have attracted considerable attention because of their unique water-repellency and their wide range of applications. The conventional method to characterize the surface wetting properties of surfaces, including superhydrophobic surfaces, relies on measuring static… read more here.

DOI: 10.1021/acs.langmuir.2c00941
Abstract: When a water drop slides over a hydrophobic surface, it usually acquires a positive charge and deposits the negative countercharge on the surface. Although the electrification of solid surfaces induced after contact with a liquid… read more here.

DOI: 10.1103/physrevlett.129.104501
Abstract: A falling liquid drop, after impact on a rigid substrate, deforms and spreads, owing to the normal reaction force. Subsequently, if the substrate is nonwetting, the drop retracts and then jumps off. As we show… read more here.
