Surface tension and compression modulus anisotropies of a phospholipid monolayer spread on water and on formamide
Article Abstract:
A study was conducted to analyze the elastic characteristics of the low-temperature solid phase of a 1,2-distearoyl-sn-glycero-3-phophatidylcholine monolayer spread at the air-water and at the air-formamide interfaces. Experimental results indicated that the surface wave excitation method generated accurate measurements of the surface tension and of the monolayer compression modulus.

Dynamical heterogeneity in glassy o-terphenyl: Manifestation of environment changes in photoisomerization kinetics of probe molecules
Article Abstract:
A new method is described for investigating the dynamical heterogeneity in glassy mixtures by using an example of o-terphenyl (OTP). The dependence of isomerization quantum yield on light intensity is attributed to the change in the local environment of the probe molecules.

Rotational mobility of guest molecules in o-terphenyl below T(sub g)
Article Abstract:
An optical anisotropy decay technique for measuring probe rotational times in glassy materials is presented. The results show that below T(sub g)-9 K, the temperature dependence of rotation mobility was much weaker with activation energy of 70 plusmn 15 kJ/mol.
