Effect of Nanoscale Morphology on the Conductivity of Polymerized Ionic Liquid Block Copolymers
Polymerized ionic liquid (POIL) block copolymers represent a unique class of materials for fundamental studies of single ion conduction as a function of morphology in microphase-separated polymerExpand
Unexpected consequences of block polydispersity on the self-assembly of ABA triblock copolymers.
TLDR
It is demonstrated that polydisperse SBS triblockCopolymers self-assemble into periodic structures with unexpectedly enhanced stabilities that greatly exceed those of equivalent monodisperse copolymers, and it is shown that narrow dispersitycopolymers are not required for periodic nanoscale assembly.

Low-symmetry sphere packings of simple surfactant micelles induced by ionic sphericity
TLDR
It is shown that surfactant micelles also form complex, tetrahedrally closest-packed Frank–Kasper (FK) phases, and it is demonstrated that these unexpected structures arise from simultaneous optimization of interparticle electrostatic interactions and the spherical symmetry of the charged ion clouds around each micelle.

Ab Initio Modeling of Electrolyte Molecule Ethylene Carbonate Decomposition Reaction on Li(Ni,Mn,Co)O2 Cathode Surface.
TLDR
This work implies that the possible rate-limiting steps of the electrolyte molecule decomposition are the reactions on the decomposed organic products on the cathode surface rather than on the bare cathodes, which is commonly used in commercial Li-ion batteries. Expand
Synthetic Mimics of Bacterial Lipid A Trigger Optical Transitions in Liquid Crystal Microdroplets at Ultralow Picogram-per-Milliliter Concentrations
TLDR
These and other results suggest that these amphiphiles trigger orientational transitions at ultralow concentrations through a unique mechanism that is similar to that of Lipid A and involves formation of inverted self-associated nanostructures at topological defects in the LC droplets. Expand
Order and Disorder in High χ/Low N, Broad Dispersity ABA Triblock Polymers
Using a combination of small-angle X-ray scattering (SAXS) and transmission electron microscopy (TEM), we document the composition-dependent morphologies of 39 newExpand
Microstructure of copolymers formed by the reagentless, mechanochemical remodeling of homopolymers via pulsed ultrasound
The high shear forces generated during the pulsed ultrasound of dilute polymer solutions lead to large tensile forces that are focused near the center of the polymer chain, but quantitativeExpand
Cobalt-mediated radical polymerization routes to poly(vinyl ester) block copolymers
Cobalt-mediated radical polymerizations (CMRPs) utilizing redox initiation are demonstrated to produce poly(vinyl ester) homopolymers derived from vinyl pivalate (VPv) and vinyl benzoate (VBz), andExpand
