Synthesis and Characterization of Polyhedral Oligomeric Silsesquioxane (POSS) Based Amphiphiles
… LE/LC phase transitions were observed in Π-A isotherms over part of the experimentally accessible temperature range and were attributed to a change from a vertex-on to face-on conformation. Apparent BAM images confirmed LC islands coexisted with the LE phase. The experimentally observed …

Nanoscale Confinement Effects on Poly(ε-Caprolactone) Crystallization at the Air/Water Interface & Surfactant Interactions with Phospholipid Bilayers
… of surface pressure-area per monomer (Π−A)) isotherms for the Langmuir films at the A/W interface showed that PCL-b-PtBA copolymers, PCL triheads and PCL MNPs all formed homogenous monolayers below the dynamic collapse pressure of PCL, Π<sub>C</sub> ~11 mN•m⁻¹. For compression past the …

Synthesis and Characterization of Polyhedral Oligomeric Silsesquioxane (POSS) Based Amphiphiles
… surface pressure - area per molecule (? -A) isotherms as well as Brewster angle microscopy (BAM) at the air/water (A/W) interface. Compared with previous work on trisilanol-POSS derivatives, the results indicated that POSS-triester was surface active and formed a liquid-expanded (LE) …
