Article Abstract

Edge-functionalized graphite (EFG) is prepared via a "direct" covalent attachment of organic molecular wedges. The EFG is dispersed in N-methyl-2-pyrrolidone with a concentration as high as 0.27 mg mL(-1), leading to high-yield exfoliation of the three-dimensional graphite into two-dimensional graphene-like sheets.

High-quality narrow black phosphorus nanoribbons with nearly atomically smooth edges and well-defined edge orientation.

Black phosphorus nanoribbons (BPNRs) with a tunable bandgap and intriguing electronic and optical properties hold strong potential for logic applications. However, efficiently producing high-quality BPNRs with precise control over their size and structure remains a great challenge. Here we achieved high-quality, narrow and clean BPNRs with nearly atomically smooth edges and well-defined edge orientation at high yield (up to ~95%) through the sonochemical exfoliation of the synthesized bulk BP crystals with a slightly enlarged lattice parameter along the armchair direction.

Two-dimensional (2D) nanomaterials of quasicrystals are highly desirable as these materials may have novel physical laws and properties that the 2D crystalline materials do not have, since the crystal structures of quasicrystals are quite different from those of traditional crystals. However, producing quasicrystal nanosheets with high yield still remains challenging because quasicrystals are generally non-van der Waals (n-vdW) solids with strong chemical bonds between constituent atoms, which makes them difficult to exfoliate. Here, an efficient liquid-phase shear exfoliation (LPSE) method is developed to successfully produce atomically-thin AlCoNi quasicrystal nanosheets with a gram-scale collection.

Rotator cuff tendon-bone healing is impeded by inflammation and inadequate regeneration. This study evaluates exosome-mimetics (EMs) derived from stem cells of human exfoliated deciduous teeth (SHEDs) as a therapeutic strategy to enhance repair.SHED-EMs were synthesized via serial extrusion and characterized using transmission electron microscopy, nanoparticle tracking analysis, and Western blot.

One-dimensional (1D) van der Waals (vdW) nanowires, formed from molecular chains bonded through weak interactions, represent a significant departure from traditional nanowires by offering the potential to miniaturize functional devices to the molecular scale while maintaining crystallinity, a feature attributable to their exfoliable nature and chemically inert surfaces. However, the lack of efficient synthesis methods has hindered the exploration of their intrinsic properties and potential applications. The production of vdW nanowires has predominantly relied on the exfoliation of bulk crystals, leaving their direct synthesis largely unexplored.

The study demonstrates a scalable and reproducible method for synthesising graphene oxide (GO) nanosheets from commercial carbon fibres derived from carbonised polyacrylonitrile (PAN) polymer. An exfoliation route with nitric acid allows for the preparation of monolayer GO nanosheets with a consistent thickness of 0.9 ± 0.
