Highly branched “bottlebrush” polymers are a class of macromolecules characterized by
side chains that are densely grafted from a backbone that is typically linear. Their unique …

Three subjects in polymer and soft matter physics are outlined in the present article. The first
relates to concepts of an ideal glass transition. We describe work on ultra‐stable glass …

The melt rheology of single-chain nanoparticles (SCNPs), which are synthesized by
intrachain cross-linking of linear precursors, remains an unresolved issue. In this study, we …

Ring polymers have fascinated scientists for decades, but experimental progress has been
challenging due to the presence of linear chain contaminants that fundamentally alter …

Molecular dynamics simulations confirm recent extensional flow experiments showing ring
polymer melts exhibit strong extension-rate thickening of the viscosity at Weissenberg …

We combine linear viscoelastic measurements and modeling in order to explore the
dynamics of blends of the same-molecular-weight ring and linear polymers in the regime of …

We present a comprehensive experimental rheological dataset for purified entangled ring
polystyrenes and their blends with linear chains in nonlinear shear and elongation. In …

The considerable interest in two-dimensional (2D) materials and complex molecular
topologies calls for a robust experimental system for single-molecule studies. In this work …

Inspired by advances in the chemical synthesis of interlocking polymer architectures,
extensive molecular dynamics simulations have been conducted to study the dynamical …

Extensive molecular simulations are applied to characterize the equilibrium dynamics,
entanglement topology, and nonlinear extensional rheology of symmetric ring-linear …
