Paramagnetic Iron-Doped Hydroxyapatite Nanoparticles with Improved Metal Sorption Properties. A Bio-Organic Substrates-Mediated Synthesis
(American Chemical Society, 2014-02)
This paper describes the synthesis of paramegnetic iron-containing hydroxyapatite nanoparticles and their increased Cu2+ sorbent capacity when using Ca2+ complexes of soluble bio-organic substrates from urban wastes as ...
Lipid metabolism alterations in the neuronal response to A53T α-synuclein and Fe-induced injury
(Elsevier Science Inc, 2018-10-08)
Pathological α-synuclein (α-syn) overexpression and iron (Fe)-induced oxidative stress (OS) are involved in the death of dopaminergic neurons in Parkinson's disease (PD). We have previously characterized the role of ...
Identificação de plintita e/ou resíduo de saprolito em solos com elevado gradiente textural
(Universidade Federal de Santa MariaBrasilAgronomiaUFSMPrograma de Pós-Graduação em Ciência do SoloCentro de Ciências Rurais, 2022-03-22)
The identification of mottles such as plinthite and saprolite residue in the soil can be considered a difficult task, both in the field and in the laboratory. The incorrect identification of these redoximorphic features ...
Trace elements in magnetite from massive iron oxide-apatite deposits indicate a combined formation by igneous and magmatic-hydrothermal processes
(Elsevier, 2015)
Iron oxide-apatite (IOA) deposits are an important source of iron and other elements (e.g., REE, P, U, Ag and Co) vital to modern society. However, their formation, including the namesake Kiruna-type IOA deposit (Sweden), ...
Mecanismo inédito de imobilização de arsênio baseado em agregação orientada de nanopartículas cristalinas de (Hidr)óxidos de ferro e alumínio: evidências por microscopia eletrônica de transmissão
(Universidade Federal de Minas GeraisUFMG, 2017-06-26)
Iron and aluminium (hydr)oxides play a major role in arsenic fixation in the environment due to their capacity for arsenic uptake by adsorption or co-precipitation. Nevertheless, the mechanisms responsible for the arsenic ...
Novel gelling pectins from Zea mays husks’ agro-industrial residue and their interaction with calcium and iron (II)
(Elsevier, 2021-11)
Pectin enriched fractions were isolated from maize husks. High-power ultrasound (US) pretreatment increased the yield in pectin extraction performed through alkaline hydrolysis of ferulate-bridges followed by hydrolysis ...
