Graphene Oxide-Promoted Reshaping and Coarsening of Gold Nanorods and Nanoparticles

Abstract: This paper describes thermally induced reshaping and coarsening behaviors of gold nanorods and nanoparticles immobilized on the surface of graphene oxide. Cetyltrimethylammonium bromide-stabilized gold nanorods with an aspect ratio of ~3.5 (54:15 nm) and glutathione-capped gold nanoparticles with an average core size of ~3 nm were synthesized and self-assembled onto the surface of graphene oxide. The hybrid materials were then heated at different temperatures ranging from 50 to 300 °C. The effects of heat trea… Show more

“…This is one of the highest reported smoke reduction values for LbL fl ame retardant fi lms on polyurethane. [ 9,11,21,24 ] Reducing smoke release can reduce the risk of injury in fi re situations by allowing for better visibility to reach exits and also lowering irritant gases that can exacerbate the toxicity of other gases commonly released in fi res such as carbon monoxide. Having the lowest weight addition of 18 wt% (similar to common fl ame retardant additives), further testing (fl ame spread, open fl ame testing) was focused on Recipe B [PEI-Py/PAA+MWCNT] because weight added is an important metric (everything else being equal) when thinking about effi cacy and minimizing processing steps.…”

“…[5][6][7][8] Layer-by-layer (LbL) assembled nanocoatings have recently shown promise for reducing foam fl ammability. [9][10][11][12] LbL deposition is a simple, water-based technology that can produce multifunctional nanocoatings through nanoscale control of composition and structure. [ 13 ] The conformal nature of these coatings allows them to uniformly cover complex surfaces with varying size, shape, and porosity.…”

“…It′s worth noting that the activity of metal diseleniums catalysts is heavily dependent on their microstructure. However, due to high current densities and long‐term testing, nanorods or nanoparticles of some metal diseleniums tend to agglomerate, resulting in decreased stability and reduced catalytic activity . In order to increase the OER performance of the selenide, further improvement of the morphology and physical properties of the metal selenide is required.…”
