Journal of Applied Polymer Science, EarlyView.Kevlar is traditionally modeled as a rigid‐rod polymer, yet rheological behavior deviates from this assumption. The review introduces a novel “twist‐tie” entanglement theory for aramid polymer chains in the nematic liquid crystal state, providing a molecular explanation for deviations from rigid‐rod models. Understanding twist‐tie entanglement dynamics

Next Generation Hosts for Protein Recognition, Assembly and More
Chemistry – A European Journal, EarlyView.The original design of synthetic receptors for proteins was based on macrocycles with a hydrophobic core and a polar/charged periphery. This design, geared towards protein recognition, facilitates receptor self‐assembly. Macrocycle oligomerization, in turn, contributes to protein assembly as evidenced in many cocrystal structures.
