A perspective on experimental findings and theoretical explanations of novel dynamics at free surface and in freestanding thin films of polystyrene
Autor: K. L. Ngai, Daniele Prevosto, Simone Capaccioli
Most studies of the dynamics at the surface and in thin films of polystyrene (PS) are focused on the change of glass transition temperature from the bulk value. In this perspective, we highlight three new developments in research on the dynamics of P

Broadband local dielectric spectroscopy
Autor: Mauro Lucchesi, Daniele Prevosto, Simone Capaccioli, M. Labardi
A route to extend the measurement bandwidth of local dielectric spectroscopy up to the MHz range has been devised. The method is based on a slow amplitude modulation at a frequency Ω of the excitation field oscillating at a frequency ω and the cohe
