Chemical and structural properties of reduced graphene oxide – dependence on the reducing agent
(Springer, 2020-11-09)
Graphene oxide (GO) prepared from graphite powder using a modified Hummers method and reduced graphene oxide (rGO) obtained from GO using different reductants, i.e. sodium borohydride, hydrazine, formaldehyde, sodium ...
Effect of Microwave Treatment in a High Pressure Microwave Reactor on Graphene Oxide Reduction Process—TEM, XRD, Raman, IR and Surface Electron Spectroscopic Studies
(MDPI, 2021-09-30)
Reduced graphene oxide (rGO) was prepared by chemical reduction of graphene oxide (GO) (a modified Hummers method) in aqueous solutions of hydrazine (N2H4), formaldehyde (CH2O), formic acid (HCO2H) accompanied by a microwave ...
Surface Study of Fe3O4 Nanoparticles Functionalized with Biocompatible Adsorbed Molecules
(Frontiers Media SA, 2019-10-04)
Surfaces of iron oxide of ferrimagnetic magnetite (Fe3O4) nanoparticles (MNPs) prepared by Massart’s method and their functionalized form (f-MNPs) with succinic acid, L-arginine, oxalic acid, citric acid and glutamic acid ...
C sp2/sp3 hybridisations in carbon nanomaterials – XPS and (X)AES study
(Elsevier, 2018-05-05)
Shape of the C KLL (KVV) Auger spectrum provides a measure of C sp2/sp3 hybridisations, alternative to C 1s spectra fitting. Due to a smaller kinetic energy of C KLL electrons than C 1s photoelectrons the investigated ...
Valorizing the Unexplored Filtration Waste of Brewing Industry for Green Silver Nanocomposite Synthesis
(MDPI, 2022-01-28)
The brewing industry generates a substantial amount of by-products rich in polyphenols, carbohydrates, sugars, sulfates, nitrogen compounds, organic carbon, and several elements, including chlorine, magnesium, and phosphorus. ...
Valorization of Brewery Wastes for the Synthesis of Silver Nanocomposites Containing Orthophosphate
(MDPI, 2021-10-10)
Brewery wastes from stage 5 (Wort precipitate: BW5) and stage 7 (Brewer’s spent yeast: BW7) were valorized for the synthesis of silver phosphate nanocomposites. Nanoparticles were synthesized by converting silver salt in ...
