Investigation of structural morphology and electrical properties of graphene-C₆₀ hybrids

This article reports on the electrophoretic deposition of C₆₀ on graphene. The results suggest that graphene based C₆₀ structures are attractive as flexible transparent electrodes and are excellent electron accepting/charge transport materials for the construction of efficient photovoltaic devices.

3D-printed and injection molded polymer matrix composites with 2D layered materials (open access)

3D-printed and injection molded polymer matrix composites with 2D layered materials

This article reports on a study where 2D TMDs (MoS₂ and WS₂) and the 3D allotrope of carbon and graphite were incorporated into acrylonitrile butadiene styrene (ABS) and polyethylene terephthalate glycol (PETG) matrices in order to form polymer matrix composites (PMCs). The multipronged analysis described in this study was motivated by the purpose to fuse together topics of low-cost, additive manufacturing with 2D layered materials, and studying their ensuing mechanical and tribological properties.

Biocompatible, large-format, inkjet printed heterostructure molybdenum disulfide-graphene photodetectors on conformable substrates (open access)

Biocompatible, large-format, inkjet printed heterostructure molybdenum disulfide-graphene photodetectors on conformable substrates

This article describes an inkjet printed, biocompatible, heterostructure photodetector that was constructed using inks of photo-active molybdenum disulfide (MoS2) and electrically conducting graphene which facilitated charge collection of the photocarriers. The importance of such devices stems from their potential utility in age-related-macular degeneration, which is a condition where the photosensitive retinal tissue degrades with aging, eventually compromising vision. The absence of effective therapeutic remedies for patients with this disorder has motivated the development of such devices to restore some degree of visual function.
