Sentences with phrase «graphene oxide nanoparticles»
As Jake Lanphere, a UC Riverside graduate student who co-authored the paper, which was published in the journal Environmental Engineering Science («Stability and Transport of Graphene Oxide Nanoparticles in Groundwater and Surface Water»), explained to Nanoclast in an email interview: «Other studies have looked at ideal lab conditions that do not necessarily reflect the conditions one might find in aquatic environments.

However, this approach requires precision engineering of nano - features (in a detection chip), complex optical setups, novel nano - probes (such as graphene oxide, carbon nanotubes, and gold nanorods) or additional amplification steps such as aggregation of nanoparticles to achieve sensitive detection of biomarkers.
Researchers at Umeå University, together with researchers at Uppsala University and Stockholm University, show in a new study how nitrogen doped graphene can be rolled into perfect Archimedean nano scrolls by adhering magnetic iron oxide nanoparticles on the surface of the graphene sheets.
By this method they obtain anchoring sites for the iron oxide nanoparticles that are decorated onto the graphene sheets in a solution process.
The nanoscrolls can be visualized as traditional «Swiss rolls» where the sponge - cake represents the graphene, and the creamy filling is the iron oxide nanoparticles.
Moreover, they showed that by removing the iron oxide nanoparticles by acid treatment the nanoscrolls again open up and go back to single graphene sheets
They additionally found the reason why their battery works: the spacing of the iridium catalyst nanoparticles in the reduced graphene oxide (rGO) cathode favor the production of lithium superoxide (LiO2) and inhibit peroxide (Li2O2) generation.
