Modeling electrode polarization in dielectric spectroscopy: Ion mobility and mobile ion concentration of single-ion polymer electrolytes.
A novel method is presented whereby the parameters quantifying the conductivity of an ionomer can be extracted from the phenomenon of electrode polarization in the dielectric loss and tan deltaExpand
Nanocasting nanoporous inorganic and organic materials from polymeric bicontinuous microemulsion templates
Recent work is reviewed in which nanoporous polyethylene, derived from a polymeric bicontinuous microemulsion, is used as a nanocasting template in the synthesis of a catalogue of porous materials,Expand
Nanoporous Materials Derived from Polymeric Bicontinuous Microemulsions
We demonstrate a universal approach to the synthesis of nanoporous materials with pore structures that are highly precise replications of bicontinuous microemulsions. The materials can be formed atExpand
Hierarchically structured materials from block polymer confinement within bicontinuous microemulsion-derived nanoporous polyethylene.
The unique structure of the polyethylene template is exploited to generate new hierarchically structured porous monoliths, which are spatially variant in a complex manner, due to the three-dimensionally interconnected nature of the confining geometry and its distribution in pore sizes. Expand
High-temperature nanoporous ceramic monolith prepared from a polymeric bicontinuous microemulsion template.
Microscopy and gas sorption measurements suggest a well-defined pore size distribution spanning roughly 60-100 nm, sizes previously unattainable through related techniques. Expand
Surfactant-induced assembly of enzymatically-stable peptide hydrogels.
The secondary structure of a linear nonapeptide composed of a hydrophobic alanine/phenylalanine core flanked by hydrophilic acid/amine units is characterized and anionic surfactant sodium dodecyl sulfate induces the formation of β-sheets and macroscopic gelation in this otherwise unstructured peptide.

Hierarchically porous silica prepared from ionic liquid and polymeric bicontinuous microemulsion templates
Polymeric bicontinuous microemulsions (BμE) are unique disordered morphologies found in well-designed ternary blends of two immiscible homopolymers and a diblock copolymer surfactant. ByExpand
Stress Relaxation in Epoxy Thermosets via a Ferrocene-Based Amine Curing Agent
Physical stress relaxation in rubbery, thermoset polymers is limited by cross-links, which impede segmental motion and restrict relaxation to network defects, such as chain ends. In parallel, theExpand
A multi-stimuli responsive, self-assembling, boronic acid dipeptide.
It is shown for the first time that the binding of polyols to the BA functionality can modulate a peptide between its assembled and disassembled states. Expand
