Dynamics of Poly Dimethyl Amino Ethyl Methacrylate / water glycerol mixtures
We want to study the microscopic mechanisms of solvent dynamics such as water and glycerol in ahydrophilic polymer. Dielectric measurements suggest that below the glass... -
Molecular weight dependence of 2D-confined dynamics in glass-forming systems
We seek to explore the dynamics of glass forming systems upon extreme 2D-confinement. These experiments are motivated by preliminary experiments on oligomers and macromolecules... -
Exploring Polymer Vibrations under Extreme Confinement: Substrate Effects
We seek to explore extreme confinement on the vibrational density of states of polyethylene oxide (PEO) over a wide energy-transfer range (10-3000 cm-1). These experiments are... -
Dynamics of Polymer/Polymer nanocomposites
By adding only about 1% of soft polymer nanoparticles to natural rubber, a dramatic decrease in the viscosity (more than 50%) is induced. Our recent time of flight measurements... -
Is dynamic asymmetry the essential ingredient in the (universal?) 'strong-fra...
We want to elucidate whether the so-called ¿strong-fragile¿ transition reported for water mixtures is a universal phenomenon driven by confinement effects originated by the...
