Oxygen permeability of fully condensed lipid monolayers

Article Abstract:

The oxygen permeation resistance of highly condensed monolayers composed of a homologous series of saturated diacyl phosphatidylcholine lipids was measured using a novel technique that combined micromanipulation and electrochemical techniques. The use of lipid monolayer-coated air microbubbles allowed measurement of the oxygen permeation resistance of fully condensed lipid monolayers that were previously unavailable using classical film balance techniques.

Ultrafast chelation dynamics of cyclopentadienyl manganese tricarbonyl derivatives with pendant sulfides

Article Abstract:

The ring formation with the organometallics as a mechanism for an ultrafast photoswitch is investigated. The photoinduced dynamics of cyclopentadienyl manganese tricarbonyl derivatives are investigated in n-heptane solution on the ps to micro seconds scale by UV-pump IR-probe transient absorption spectroscopy.

Driving forces of phase transitions in surfactant and lipid systems

Article Abstract:

A thermodynamic study of the driving forces of phase transitions in surfactant and lipid system is presented. The driving forces of phase transitions can be determined from the appearance of the phase diagram using the approach based on van der Waals differential equation.
