  • Elastic anisotropy of liquid crystals elastomers is typically measured at low frequencies for the applications such as soft robotics, actuators, and origami. Here the authors study the elastic anisotropy of LCE using Brillouin light spectroscopy at gigahertz frequencies such as radio frequencies or 5 G cellular networks.

  • Synthetic polymer nano-objects with well-defined hierarchical structures are important for a wide range of applications such as nanomaterial synthesis, catalysis, and therapeutics. Here the authors demonstrate the strategy of fabricating controlled hierarchical structures through self-assembly of folded synthetic polymers.

  • Liquid-phase-processable graphene nanoribbons (GNRs) over 200 nm long and with well-defined structures have now been synthesized by a bottom-up method, and are found to have a large optical bandgap of 1.88 eV. Scanning probe microscopy revealed highly ordered self-assembled monolayers of the GNRs, and the high intrinsic charge-carrier mobility of individual ribbons was characterized by terahertz spectroscopy.

  • The realization of ultrastable, nanostructured glassy polymer films by pulsed-laser evaporation is reported. Compared with standard poly(methyl methacrylate) glass, these polymer glasses are 40% less dense and have a 40-degree-higher glass transition temperature. Their unique properties, which are a manifestation of their globular nanostructure, should make these glasses attractive for applications where weight and stability are critical.
