For the last 20 years, it has been common lore that the free energy of RNA duplexes formed from canonical Watson–Crick base pairs (bps) can be largely approximated with dinucleotide bp parameters and a few simple corrective constants that are duple

Summary Conjugated polymers possess unique optoelectrical properties. Characterizing their synthesis and mechanical processability is crucial for tailored applications. Their poor solubility presents a universal challenge, however. Here, we report a

Structure and dynamics are examined for unentangled randomly-sulfonated polystyrene ionomer samples with cesium as counterion, using the X-ray scattering, DSC, and linear viscoelasticity (LVE) measurements. The large size of cesium cation leads to lo

We present a coarse-grained (CG) molecular dynamics (MD) simulation study of polymer nanocomposites (PNCs) containing nanorods with homogeneous and patchy surface chemistry/functionalization, modeled with isotropic and directional nanorod-nanorod att

The nonlinear stress–strain response of synthetic and biological networks and gels manifested in a monotonic increase of an instantaneous modulus is a result of the nonlinear deformation of individual network strands. To describe this behavior, we

The dynamic heterogeneity of polymer chains is characterized by the lower correlation times of its end Kuhn segments with respect to those of the middle segments. In this study, the heterogeneity was investigated using molecular dynamics simulation o

It is shown that, in the melts of linear macromolecules, the effects of dynamic heterogeneity associated with the presence of end segments are not vanishingly small in the limit $$N \to \infty $$, where $$N$$ is the number of Kuhn segments in the mac
