Theory
LF I- Liquid-fluid interfaces I (MAFR)
Surface tension and its physical implications. Measurement of surface/interfacial tension. Thermodynamic quantities at interfaces. Monolayers.
LF II- Liquid-fluid interfaces II (JMV)
Kinetics properties of interfacial layers: adsorption dynamics and dilatational rheology. Theoretical and empirical models, diffusion coefficient and dilatational parameters. Experimental methods. Examples and case studies: surfactants, proteins, polymers and microgels.
WP I- Wetting phenomena I (MARV)
Adhesion. Contact angle hysteresis. Fundamental equations. Contact angle measurement and interpretation.
WP II- Wetting phenomena II (MARV)
Extreme wettability: liquid/air-repellent, liquid/air-retaining. Singular techniques (based on the drop motion).
