Lipid Melting Transitions Involve Structural Redistribution of Interfacial Water

Sylvie Roke, Halil Ibrahim Okur, Filip Kovacik, Tereza Schönfeldová

Morphological and gel-to-liquid phase transitions of lipid membranes are generally considered to primarily depend on the structural motifs in the hydrophobic core of the bilayer. Structural changes in the aqueous headgroup phase are typically not considere ...

Determination and evaluation of the nonadditivity in wetting of molecularly heterogeneous surfaces

Francesco Stellacci, Michele Ceriotti, Sylvie Roke, Quy Ong Khac, Halil Ibrahim Okur, David Mark Wilkins, Zhi Luo, Anna Murello, Filip Kovacik

The interface between water and folded proteins is very complex. Proteins have "patchy" solvent-accessible areas composed of domains of varying hydrophobicity. The textbook understanding is that these domains contribute additively to interfacial properties ...

Hydration mediated interfacial transitions on mixed hydrophobic/hydrophilic nanodroplet interfaces

Sylvie Roke, Halil Ibrahim Okur, Nikolay Smolentsev, Rüdiger Scheu, Filip Kovacik

Interfacial phase transitions are of fundamental importance for climate, industry, and biological processes. In this work, we observe a hydration mediated surface transition in supercooled oil nanodroplets in aqueous solutions using second harmonic and sum ...
