For many years the determination of the shear viscosity of interfacial layers has been source
of strong controversy. This is mainly because different techniques provided different values …

During emulsification and further processing (eg, pasteurizing), the oil–water interface is
mechanically and thermally stressed, which can lead to oil droplet aggregation and …

In the lungs, the Laplace pressure, ΔP= 2γ/R, would be higher in smaller alveoli than larger
alveoli unless the surface tension, γ decreases with alveolar interfacial area, A, such that 2ε> …

Two-point microrheology was applied to a homogeneous (DPPC monolayers) and a
heterogeneous (asphaltene films) interface. For DPPC monolayers, both the longitudinal …

Digitonin, a steroidal saponin obtained from the foxglove plant (Digitalis purpurea), displays
a wide spectrum of biological properties and is often used as a model in mechanistic …

A new approach to the analysis of nonlinear surface dilational rheological properties was
developed with the aim to enlarge the accessible range of surface pressures. The dilational …

Hypothesis In-plane interactions among adsorbed phospholipids (PL) at an oil–water
interfacial film may vary based on the size of the headgroup or the size and saturation of the …

Biologically relevant monolayer and bilayer films often consist of micron-scale high viscosity
domains in a continuous low viscosity matrix. Here we show that this morphology can cause …

Photodynamic therapy of cancer comprises the activation of photosensitizer molecules
delivered to cancer cells, to generate reactive oxygen species that mediate cytotoxicity. In …

Pulmonary surfactant, which is a complex mixture of lipids and proteins, plays a key role in
the functional properties of the respiratory system. Lipids form complexes with proteins to …
