AbstractPlastic films are among the most used materials. In many applications, both high strength and low thickness are required. The thickness of free-standing plastic films has recently been reduced to micrometres, 200 nm and even 60 nm. Pushing this boundary further faces considerable challenges, as processability conflicts with stability at the ‘ultrathin’ scale (below ~100–200 nm).

AbstractElectronic systems and devices operating at significant power levels demand sophisticated solutions for heat dissipation. Although materials with high thermal conductivity hold promise for exceptional thermal transport across nano- and microscale interfaces under ideal conditions, their performance often falls short by several orders of magnitude in the complex thermal interfaces typical of real-world applications.

AbstractHierarchical assembly is used to construct complex materials using elementary building units, mainly depending on the non-covalent interactions involving dynamic bonds. Here we present a hierarchical assembly strategy to build highly crystalline tubular frameworks. A multi-level assembly process driven by dynamic covalent bonds and coordination bonds is shown to produce a supramolecular nanotubular framework and three tubular covalent organic frameworks (COFs).

AbstractScanning probe microscopy and scanning transmission electron microscopy (STEM) are powerful tools to trigger atomic-scale motions, pattern atomic defects and lead to anomalous quantum phenomena in functional materials. However, these techniques have primarily manipulated surface atoms or atoms located at the beam exit plane, leaving buried atoms, which govern exotic quantum phenomena, largely unaffected.
