Small molecule desorption prior to dissolution of a polymeric glass
(Wiley Subscription Services, Inc., A Wiley Company, 2006-07-15)
Poly(methyl methacrylate) (PMMA) discs in various molecular weights (M-w) were prepared by free-radical polymerization. Pyrene (Py) was introduced during polymerization as a fluorescence probe. In situ steady state ...
Monitoring diffusion of reptating polymer chains by a direct energy transfer method: A Monte Carlo simulation
A kinetic Monte Carlo method was used to simulate the diffusion of reptating polymer chains across an interface. A time-resolved fluorescence technique in conjunction with a direct energy transfer method was used to measure ...
Breakdown of the Stokes-Einstein relation in supercooled liquids
(TRANS TECH PUBLICATIONS LTD, 2004)
Breakdown of the Einstein-Stokes relation in undercooled liquids is one of the unsolved problems in the theory of liquids. The self-diffusion coefficient follows the temperature dependence of the Einstein-Stokes equation ...
