Piezo-optical study of the behaviour of short chain liquid polymers
The molecules of short chain liquid polymers exist in a dynamic mixture of conformations. Intermolecular interactions are important, rendering statistical mechanical models inappropriate: instead, free volume concepts are used. Evidence of an ordered liquid state in the n-alkanes is disputed, and …

Coupling of the electrical, mechanical and optical response in polymer/liquid-crystal composites
… droplets embedded in a polymer matrix may enable optical switching in the composite film through the alignment of the LC director along an external electric field. When a ferroelectric material is used as host polymer, the electric field generated by the piezoelectric effect can orient the …

Testing theories for thermal transport using high pressure
… the pressure dependent thermoreflectance and piezo-optical coefficient of metal film transducers—Al, Ta, and Au(Pd) alloy (≈5 at. % Pd) at a laser wavelength of 785 nm. The thermoreflectance of Ta and Au(Pd) are comparable to that of Al at ambient conditions and independent of pressure in the …
