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.

Cache-Aided General Linear Function Retrieval (open access)

Cache-Aided General Linear Function Retrieval

This article designs a novel coded caching scheme that outperforms uncoded caching schemes that either use unicast transmissions or let each user recover all files in the library. It extends the scope of the authors’ past work that only considered the class of linear functions that operate element-wise over the files.
