Ion Transport, Viscoelastic, and Thermal Properties of Several Poly(Ethylene Glycol) and Poly(Propylene Glycol) Based Polymer Electrolytes
This dissertation explores the relationship between ionic conductivity, viscosity, and thermal properties of several MePEG and MePPG based copolymer electrolytes. In particular two main copolymer modifications have been investigated namely copolymerization with "bulky groups" and cross …

Polyethylene glycol stationary phases for capillary gas chromatography
… are the high molecular weight polyethylene glycols (HMW PEG) which are commercially available in a wide range of molecular weights, cross-linkable and uncross-linkable (Carbowax 2OM and 4OM, the Superox series, etc.). Their most outstanding features are their unique polarity and selectivity; …

Analysis of Polyethylene Glycol in the α-Hemolysin Nanopore
… blockade. In this thesis we look at polyethylene glycol (PEG) as it enters and blocks current through a single alpha hemolysin pore. We report the effects of ionic strength, PEG size, and applied voltage on the depth and duration of the current blockades. We also apply autocorrelation analysis on …

Polyethylene glycol copolymer nanocarriers: Biocompatibility, uptake and intracellular trafficking in neurons
Spinal cord injury (SCI) causes neuronal death and leads to persistent loss of motor and sensory functions. Treatment of SCI is challenging as axon regeneration from damaged neurons is largely inhibited in the central nervous system (CNS). Moreover, targeting therapeutics to damaged CNS neurons is …

Interactions Between Polyethylene Glycol Chains and Proteins and Chemically Selective Surfaces
The results presented in this work directly demonstrate that far from presenting an inert and repulsive steric barrier, PEG brushes can interact differently with different chemically selective surfaces. Clearly, PEG is not an inert, simple polymer whose biological activity, especially, vis-a-vis …
