Aluminum mobility in mildly acidic mine drainage: Interactions between hydrobasaluminite, silica and trace metals from the nano to the meso-scale
(Elsevier B.V., 2019)
Aluminum precipitates control the hydrochemistry and mineralogy of a broad variety of environments on Earth (e.g., acid mine drainage, AMD, coastal wetlands, boreal and alpine streams, tropical acid sulfate soils, laterites ...
Strain- and electric field-induced band gap modulation in nitride nanomembranes
(2013-05-15)
The hexagonal nanomembranes of the group III-nitrides are a subject of interest due to their novel technological applications. In this paper, we investigate the strain- and electric field-induced modulation of their band ...
The effect of anodization parameters on the aluminum oxide dielectric layer of thin-film transistors
(2020-05-01)
Aluminum-oxide (Al2O3) is a low cost, easily processable and high dielectric constant insulating material that is particularly appropriate for use as the dielectric layer of thin-film transistors (TFTs). Growth of ...
Competition between humic substances and α-amino acids by metal species
(2004-08-30)
The aim of the present work was to carry out experimental comparison between humic substances (HS) and representative α-amino acids (methionine, methionine sulfoxide and cysteine hydrochloride) in relation to the complexation ...

Interaction of arsenic species with tropical river aquatic humic substances enriched with aluminum and iron
(2016-04-01)
The mobility and bioavailability of arsenic (As) are strongly controlled by adsorption/precipitation processes involving metal oxides. However, the organic matter present in the environment, in combination with these oxides, ...
