The effect of the starting material on the thermal decomposition of iron oxyhydroxides
(Springer, 2003-02)
The effect of the iron precursor on the thermal decomposition of iron oxyhydroxides was studied by DSC, DTA and TG in this work. Samples were prepared from iron nitrate, iron sulfate and iron chloride and the thermal curves ...
Nitric oxide, nitrosyl iron complexes, ferritin and frataxin: A well equipped team to preserve plant iron homeostasis
(Elsevier Ireland, 2011-11)
Iron is a key element in plant nutrition. Iron deficiency as well as iron overload results in serious metabolic disorders that affect photosynthesis, respiration and general plant fitness with direct consequences on crop ...
Nitric Oxide and Frataxin: Two Players Contributing to Keep Cellular Iron Homeostasis.
(Oxford University Press, 2009-06-25)
BackgroundNitric oxide (NO) is a signalling and physiologically active molecule in animals, plants and bacteria. The specificity of the molecular mechanism(s) involved in transducing the NO signal within and between cells ...
Surface and interface interplay on the oxidizing temperature of iron oxide and Au-iron oxide core-shell nanoparticles
(Royal Society of Chemistry, 2016-07)
This article presents the effect of oxidation temperature on shape anisotropy, phase purity and growth of core-shell heterostructures and consequently their effect on structure-property relationships. Iron oxide and Au-iron ...
Nitric oxide, nitrosyl iron complexes, ferritin and frataxin: a well equipped team to preserve plant iron homeostasis
(Elsevier Ireland, 2011-04)
Iron is a key element in plant nutrition. Iron deficiency as well as iron overload results in serious metabolic disorders that affect photosynthesis, respiration and general plant fitness with direct consequences on crop ...
A new catalyst material based on niobia/iron oxide composite on the oxidation of organic contaminants in water via heterogeneous Fenton mechanisms
(Elsevier Science, 2007-01)
The present work describes the preparation of novel materials based on niobia (Nb2O5)/iron oxides and their use as catalyst on oxidizing reactions of organic compounds in aqueous medium with hydrogen peroxide. These new ...
Decoding plant responses to iron deficiency: Is Nitric Oxide a central player?
(Landes Bioscience, 2014-10-01)
Plants respond to iron deprivation by inducing a series of physiological and morphological responses to counteract the nutrient deficiency. These responses include: (i) the acidification of the extracellular medium, (ii) ...
Decoding plants adaptive responses to iron deficiency: Is Nitric Oxide a central player?
(Landes Bioscience, 2008-10)
Plants respond to iron deprivation by inducing a series of physiological and morphological responses to counteract the nutrient deficiency. These responses include: (i) the acidification of the extracellular medium, (ii) ...
Visible light enhanced Cr(VI) removal from aqueous solution by nanoparticulated zerovalent iron
(Elsevier, 2014-02)
Cr(VI) removal using nanoparticulated zerovalent iron is enhanced under visible light in comparison with the dark process. Using an Fe:Cr(VI) molar ratio (MR) of 1, 77% removal was obtained after two hours under irradiation, ...
