Tribological Properties of (EN AW-AlCu4MgSi(A)) Aluminium Alloy Surface Layer After Ball Burnishing (open access)

Tribological Properties of (EN AW-AlCu4MgSi(A)) Aluminium Alloy Surface Layer After Ball Burnishing

Article presents the tribological properties of (EN AW-AlCu4MgSi(A)) aluminium alloy surface layer after ball burnishing. EN AW-AlCu4MgSi(A) aluminium alloy is widely used as a structural material in aerospace and automotive applications. The authors have subjected it to grinding, polishing and ball burnishing. The authors have performed ball-on-disk tribological tests. We have also determined normalized 3D roughness parameters. High surface smoothness turns out to be obtainable. Favorable effect of the ball burnishing on the tribological properties of the alloy are seen. Results will be presented at the International Scientific Conference BALTTRIB, 2015.

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.
