Counterbalance between Surface and Confinement Effects As Studied for Amino-Terminated Poly(propylene glycol) Constraint in Silica Nanopores
Kiprop Kipnusu, Wycliffe; M. Elmahdy, Mahdy; Elsayed, Mohamed; Krause-Rehberg, Reinhard; Kremer, Friedrich American Chemical Society (2019)Broadband dielectric spectroscopy (BDS) and orthopositronium annihilation lifetime spectroscopy (PALS) are combined to study the molecular dynamics and the free volume of poly(propylene glycol) terminated with amino end ... -
Glassy dynamics predicted by mutual role of free and activation volumes
Kiprop Kipnusu, Wycliffe; Elsayed, Mohamed; Iacob, Ciprian; Pawlus, Sebastian; Krause-Rehberg, Reinhard; Paluch, Marian Royal Society of Chemistry (2019)Broadband Dielectric Spectroscopy (BDS) at elevated pressures and Positron Annihilation LifetimeSpectroscopy (PALS) are employed to elucidate the importance of the ratio of activation and freevolumes during vitrification. ...
