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.

This Side of the Border: The Mexican Revolution through the Lens of American Photographer Otis A. Aultman

This presentation discusses the Mexican Revolution, as seen through the camera lens of American photographer Otis A. Aultman. In 2009, El Paso Public Library's Archivist Marta Estrada received a grant from the UNT Libraries to digitize a portion of their Otis Aultman Photograph Collection and add it to The Portal to Texas History. El Paso Public Library's collection on the Portal consists of more than 500 digitized glass plate negative photographs that documents the Mexican Revolution through the eyes of Mr. Aultman, many of which have not been seen for a century.

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.
