Adsorption of arsenic onto films based on chitosan and chitosan/nano-iron oxide
(Elsevier Science, 2020-12)
Films made from neat chitosan and chitosan with magnetic nanoparticles (MNPs) were tested as adsorbents of arsenate ions. Sorption equilibrium and sorption kinetics studies are reported, including different models applied ...
Chitosan-Derived Iron Oxide Systems for Magnetically Guided and Efficient Water Purification Processes from Polycyclic Aromatic Hydrocarbons
(American Chemical Society, 2017-01)
Chitosan and pyrolyzed chitosan, acting as protective frameworks of magnetic nanoparticles (magnetite/maghemite and/or metallic Fe), have been investigated to be used in magnetically guided water remediation processes from ...
Pushing the photodelivery of nitric oxide to the visible: Are {FeNO}7 complexes good candidates?
(Royal Society of Chemistry, 2017-11)
Photodelivery of NO requires stable compounds which can be made reactive by irradiation with (visible) light. Traditional {MNO}6 complexes require a substantial ligand design to shift their absorption spectra to the ...
The effect of incorporation of iron in cerium oxide structure on reducibility and catalytic performance for methane oxidation in diluted streams
(Elsevier, 2019-06)
Iron-doped ceria solids were synthesized through the citrate route. The incorporation of iron in the structure of ceria produced changes in the shape of the crystallites constituting the solid particles and the pore ...
Iron oxide nanoparticles and VOx/Hexadecylamine nanotubes composite
(Elsevier Science, 2008-07)
In this work, we present the synthesis and characterization of a hybrid nanocomposite constituted by iron oxide nanoparticles and vanadium oxide/Hexadecylamine (VOx/Hexa) nanotubes. Transmission Electron Microscopy (TEM) ...
The era of nitric oxide in plant biology: Twenty years tying up loose ends
(Academic Press Inc Elsevier Science, 2019-04-01)
Nitric oxide (NO) is an essential signal molecule to maintain cellular homeostasis in uni and pluricellular organisms. Conceptually, NO intervenes as much in sustaining basal metabolic processes, as in firing cellular ...
Iron oxide mineralogy in Mollisols, Aridisols and Entisols from southwestern Pampean region (Argentina) by environmental magnetism approach
(Elsevier Science, 2020-03)
Ferromagnetic compounds of seven southwestern soils from Pampean region comprise iron oxides and oxyhydroxides that have an important role, because of their high surface reactivity, controlling soil adsorption and ...
