Amphiphilic single and double networks: a small-angle X-ray scattering investigation
(2016)We investigated the microphase-separated morphologies of water-swollen amphiphilic single and double polymer networks using small-angle X-ray scattering (SAXS). The networks consist of (i) a first conetwork containing ...

Article
Covalent amphiphilic polymer networks
(2003)The recent literature on chemically cross-linked amphiphilic polymer networks is reviewed. The main subjects covered are network synthesis, characterization, modeling and applications. Special mention is made to more modern ...

Microphase separation in ABA triblock copolymer-based model conetworks in the bulk: Effect of loop formation
(2006)This work estimates the free energy and domain size and predicts the phase diagram of microphase-separated model polymer conetworks, consisting of end-linked ABA triblock copolymers with cross-link points of relatively low ...

Microphase separation in the bulk in ABA triblock copolymer-based model conetworks: Effects of core crowding and loop formation
(2013)The microphase separation in the bulk, in the strong segregation limit, of model conetworks based on end-linked ABA triblock copolymers was investigated by calculating and minimizing the total Gibbs free energy for the ...

Microphase separation under constraints: A molecular thermodynamic theory for polyelectrolytic amphiphilic model networks in water
(2004)The aqueous aggregation behavior of covalent model networks comprising amphiphilic ABA triblock copolymers with hydrophilic ionic mid-blocks and hydrophobic non-ionic end-blocks was studied by formulating a molecular ...

A morphological analysis of the macro motor unit potential
(1999)The technique of macro EMG is used to investigate the motor unit architecture in a number of pathological conditions. Amplitude and area are the most commonly used criteria, but these parameters alone are not sufficient ...

A preliminary RAPD-PCR analysis of Cimicifuga species and other botanicals used for women's health
(2002)Traditional taxonomic methods of botanical identification that rely primarily on morphological observations cannot be used efficiently when only powdered plant materials are available. Thus, our objectives were to determine ...
