The redox state influences the interaction of ubiquinones with phospholipid bilayers
Differential scanning calorimetry (DSC) has been used to study the interaction of ubiquinones (UQn) and their reduced forms, ubiquinols (UQnH2), with dipalmitoylphosphatidylcholine (DPPC) in multilamellar vesicle...

Dichroic Ratio and Thermal Diffusivity Measurements on Polydiacetylene Single Crystal Films by Photothermal Probe Beam Deflection
Substituted diacetylenes have been polymerized by low energy electron irradiation, leading to single crystal polymers. Films thicknesses can be controlled by adjusting the incident electron energy. The work re...
