Biogenic nanoparticles: copper, copper oxides, copper sulphides, complex copper nanostructures and their applications
(Springer, 2013-09-01)
Copper nanoparticles have been the focus of intensive study due to their potential applications in diverse fields including biomedicine, electronics, and optics. Copper-based nanostructured materials have been used in ...
Copper nanoparticles grown under hydrogen: Study of the surface oxide
(Elsevier, 2011)
Copper nanoparticles with sizes between 10nm and 50nm were grown by condensation in hydrogen
at pressures from 10 Pa to 1200 Pa. The crystallite size ranged from 10nm to 25nm using the Scherrer
method. X-ray diffraction ...
Graphene Oxide as a Platform for Copper Pentacyanonitrosylferrate Nanoparticles and their Behavior in the Electro-oxidation of N-Acetylcysteine
(Wiley-Blackwell, 2020-07-01)
This work describes the preparation of graphene oxide by the Modified Hummers Method and the chemical modification of its surface with nanoparticles of copper pentacyanonitrosylferrate(III) (GOCuNP). The materials obtained ...
Oxidation of copper nanoparticles in water: mechanistic insights revealed by oxygen uptake and spectroscopic methods
(Royal Society of Chemistry, 2013-02)
Oxidation of aqueous ∼8 nm unprotected copper nanoparticles takes place under air in approximately 2 hours at 30 °C to give Cu2+ as a final product through an intermediate Cu+ species. At 5 °C the process is about 5 times ...
Copper nanoparticles and reduced graphene oxide modified a glassy carbon electrode for the determination of glyphosate in water samples
(2020-01-01)
A novel electrochemical sensor based on a glassy carbon electrode, modified with reduced graphene oxide and copper nanoparticles (GC/rGO-CuNPs), was developed for the determination of glyphosate herbicide (GLY) by differential ...
Cyclodextrin inclusion compound crystals for growth of Cu-Au core-shell nanoparticles
(Springer, 2015)
The preparation and structural elucidation of the 2 alpha-cyclodextrin/decylamine inclusion compound (IC) by proton nuclear magnetic resonance, rotating frame overhauser effect spectroscopy and powder X-ray diffraction ...
