How water wets and self-hydrophilizes nanopatterns of physisorbed hydrocarbons. Our experiments evidence that water molecules can very effectively hydrophilize initially hydrophobic surfaces that consist of weakly bound hydrocarbon carpets.

Dry Two-Step Self-Assembly of Stable Supported Lipid Bilayers on Silicon Substrates. We analyze a cleanroom-compatible method for dry fabrication of stable SLBs directly on silicon surfaces, which self-assemble without hydration. Published in International Journal of Molecular Sciences (2020):
Study of nitrogen implantation in Ti surface using plasma immersion ion implantation & deposition technique as biocompatible substrate for artificial membranes. The formation of artificial membranes was confirmed by AFM, measuring the topography at different temperatures and performing force curves. Published in Materials Science and Engineering: C (2020):
AFM image for the DPPC at 24 °C (a), 38 °C (b), 47 °C (c) and 56 °C (d) at the same scanning area.
Wetting properties of hydrothermally synthesized crystalline CuFeO2 delafossite porous surfaces. After annealing treatment at relatively low temperatures T > 300 C (Tmelt $ 1100 C), the CuFeO2 surface displayed superhydrophilicity and a rapid absorption of H2O droplets via its intergranular porosity. Published in Materials Letters (2019).

Surface Morphology of Vapor-Deposited Chitosan: Evidence of Solid- State Dewetting during the Formation of Biopolymer Films. Our work shows that ultrathin biopolymer films can undergo dewetting during film formation, even in the absence of solvents and thermal annealing. Published in ACS BioMacromolecules (2016):
