Symmetric Blocking
(Elsevier Science, 2015-11)
We present three different techniques that use information about symmetries detected in the input formula to block the expansion of diamonds in a modal tableau. We show how these blocking techniques can be included in a ...
Facile one-pot synthesis and solution behavior of poly(acrylic acid)-block-polycaprolactone copolymers
(Elsevier Science, 2019-01)
A metal-free protocol to obtain poly(acrylic acid)-block-polycaprolactone diblock copolymers (PAA-b-PCL) by a one-pot method involving simultaneous Reversible Addition-Fragmentation Chain Transfer (RAFT) and Ring Opening ...
Model Block Copolymers: Synthesis, Properties and Morphological Characterization
(Nova Science Publishers, 2014)
Block copolymers constitute a fascinating group of polymeric materials belonging to the "soft matter" family. These materials are formed by blocks of polymeric chains from different monomers. In most cases, these blocks ...
Evolution of morphologies of a PE-b-PEO block copolymer in an epoxy solvent induced by polymerization followed by crystallization-driven self-assembly of PE blocks during cooling
(Royal Society of Chemistry, 2016-03)
Polymerization-induced nanostructuration combined with crystallization-driven self-assembly was used to generate complex nanostructures in an epoxy network. A PE-b-PEO block copolymer (Mn = 1400; 50 wt% PEO), was dispersed ...
Nanostructured epoxies based on the self-assembly of block copolymers: A new miscible block that can be tailored to different epoxy formulations
(American Chemical Society, 2007-02)
Nanostructured thermosets may be obtained by the self-assembly of amphiphilic block copolymers (BCP) in a reactive solvent and fixation of the resulting morphologies by the cross-linking reaction. Nanostructuration requires ...
Coupling between mean curvature and textures in block copolymer thin films deposited on curved substrates
(Royal Society of Chemistry, 2013-08-16)
We study the dynamics of coarsening in a cylinder-forming polystyrene-block-poly(ethylene-alt-propylene) block copolymer thin film deposited on a topographically patterned substrate. Thermal annealing leads to highly ordered ...
A new information theoretic test of the Markov property of block errors in fading channels
(Institute of Electrical and Electronics Engineers, 2005-03)
This paper introduces a new and effective information theoretic test of the accuracy of the Markov property of block errors in fading channels. We apply the test to verify the validity of a first-order Markov model for ...
Mixed-morphology and mixed-orientation block copolymer bilayers
(Royal Society of Chemistry, 2014-08)
Block copolymers have attracted considerable attention due to their ability to self-assemble into highly regular structures, spanning length scales from several nanometers to over 100 nm. Block copolymers confined in thin ...
Smectic block copolymer thin films on corrugated substrates
(Royal Society of Chemistry, 2015-02)
In this work we study equilibrium and non-equilibrium structures of smectic block copolymer thin films deposited on a topographically patterned substrate. A Brazovskii free energy model is employed to analyze the coupling ...
