Journal ArticleDOI
Antioxidant chemistry of graphene-based materials and its role in oxidation protection technology†
Yang Qiu,Zhongying Wang,Alisa C. E. Owens,Indrek Külaots,Yantao Chen,Agnes B. Kane,Robert H. Hurt +6 more
TL;DR: It is shown that encapsulation of TiO2 nanoparticles in graphene nanosacks reduces undesired photo-oxidative damage to nearby organic target molecules, which suggests graphene encapsulation as a new approach to managing adverse environmental or health impacts of redox-active nanomaterials.
Journal ArticleDOI
Aerosol synthesis of cargo-filled graphene nanosacks.
Yantao Chen,Fei Guo,Ashish Jachak,Sang-Pil Kim,Dibakar Datta,Jingyu Liu,Indrek Külaots,Charles A. Vaslet,Hee Dong Jang,Jiaxing Huang,Agnes B. Kane,Vivek B. Shenoy,Robert H. Hurt +12 more
TL;DR: Water microdroplets containing graphene oxide and a second solute are shown to spontaneously segregate into sack-cargo nanostructures upon drying, promising for many applications where nanoscale materials should be isolated from the environment or biological tissue.
Journal ArticleDOI
Size distribution of unburned carbon in coal fly ash and its implications
TL;DR: In this article, a set of nine coal fly ashes, obtained from various US utilities, were fractionated by standard dry-sieving techniques, and the carbon contents of the different size fractions were measured and the nature of the carbon particles was examined.
Journal ArticleDOI
Mercury Vapor Release from Broken Compact Fluorescent Lamps and In Situ Capture by New Nanomaterial Sorbents
TL;DR: This work characterizes the time-resolved release of mercury vapor from broken CFLs and from underlying substrates after removal of glass fragments to simulate cleanup, and successfully suppressed Hg vapor escape following CFL fracture.
Journal ArticleDOI
Explosive thermal reduction of graphene oxide-based materials: mechanism and safety implications.
TL;DR: Thermal reduction of graphene oxide or graphite oxide (GO) is an important processing step in the fabrication of many graphene-based materials and devices, and some bulk solid GO samples can undergo explosive decomposition when small samples are heated slowly in inert gas environments.
