Magnetic graphene oxide as a platform for the immobilization of cellulases and xylanases: Ultrastructural characterization and assessment of lignocellulosic biomass hydrolysis
(2021-02-01)
For producing second-generation ethanol (cellulosic ethanol) and other value-added bioproducts, magnetic graphene oxide (GO-MNP) was synthesized in this work and used as the immobilization support for an industrial ...
Step-by-step synthesis of iron-oxide nanoparticles attached to graphene oxide: A study on the composite properties and architecture
(Pergamon-Elsevier Science Ltd, 2018-11)
A set of nanocomposites made of iron oxide nanoparticles covalently bonded to graphene oxide and reduced graphene oxide was successfully prepared. The synthesis was carried out in a precise step-by-step process in order ...
A new approach on synergistic effect and chemical stability of graphene oxide-magnetic nanocomposite in the heterogeneous Fenton degradation of caffeine
(2021-01-01)
Two compositions of graphene oxide-magnetite nanocomposites were studied as catalysts in the heterogeneous Fenton process. Transmission electron microscopy and X-ray diffraction revealed that the graphene oxide sheets were ...
Magnetic Graphene Oxide as a Carrier for Lipases Immobilization: An Approach for Hydrolysis of Olive Oil Emulsion
(2021-01-01)
The use of lipases in industrials processes has increased due to its ability to catalyze total or partial hydrolysis reactions of fatty acids. However, due to the difficulty of isolation and purification of lipases, as ...
Study of the influence of magnetite nanoparticles supported on thermally reduced graphene oxide as filler on the mechanical and magnetic properties of polypropylene and polylactic acid nanocomposites
(MDPI, 2021)
A study addressed to develop new recyclable and/or biodegradable magnetic polymeric materials is reported. The selected matrices were polypropylene (PP) and poly (lactic acid) (PLA). As known, PP corresponds to a non-polar ...
Reduced graphene oxide decorated with Ni-Fe-Mo permalloy obtained by sputtering
(2021-03-01)
This work illustrates an effective method for obtaining hybrid nanoparticles of Ni-Fe-Mo permalloy and reduced graphene oxide (rGO). The metallic nanoparticles were spread by the sputtering technique, which allowed a good ...
