Biosorption and desorption of lanthanum(III) and neodymium(III) in fixed-bed columns with Sargassum sp.: Perspectives for separation of rare earth metals
(Wiley-Blackwell, 2012-05-01)
Rare earth (RE) metals are essentials for the manufacturing of high-technology products. The separation of RE is complex and expensive; biosorption is an alternative to conventional processes. This work focuses on the ...
Analysis of source separation algorithms in industrial acoustic environments
(Institute of Electrical and Electronics Engineers Inc., 2015)
This paper shows the results from the computation cost evaluation of three blind source separation algorithms. The algorithms tested were: FastICA, Adaptive Algorithm Based on Natural Gradient, and Adaptive EASI Based on ...
Use of chemically modified silica with beta-diketoamine groups for separation of alpha-lactoalbumin from bovine milk whey by affinity chromatography
(Academic Press Inc. Jnl-comp Subscriptions, 1997-01-15)
Silica gel surface was chemically modified with beta-diketoamine groups by reacting the silanol from the silica surface with 3-aminopropyl-triethoxysilane and 3-bromopentanedione, With this material, copper ions were ...
A study of the effect of high inlet solids loading on a cyclone separator pressure drop and collection efficiency
(Elsevier Science SaLausanneSuíça, 2000)
Neurobiological effects of neonatal maternal separation and post-weaning environmental enrichment
(Elsevier Science, 2013-03)
Throughout the lifespan, the brain has a considerable degree of plasticity and can be strongly influenced by sensory input from the outside environment. Given the importance of the environment in the regulation of the brain ...
Synthesis and characterization of montmorillonite/polyaniline composites and its usage to modify a commercial separator
(Elsevier Science SA, 2021-01)
Composites of montmorillonite (MMT) and polyaniline (PANI) were synthetized through a facile and inexpensive method. Two samples with different MMT:PANI ratios were studied and deeply characterized by XRD, TG, zeta potential, ...
2-Mercaptoimidazole covalently bonded to a silica gel surface for the selective separation of mercury(II) from an aqueous solution
(Marcel Dekker IncNew York, 1997)
2-Mercaptoimidazole covalently bonded to a silica gel surface for the selective separation of mercury(II) from an aqueous solution
(Marcel Dekker Inc, 1997-01-01)
Silica gel with a specific surface area of 365 m(2).g(-1) and an average pore diameter of 60 Angstrom was chemically modified with 2-mercaptoimidazole. The degree of functionalization of the covalently attached molecule, ...

Xylene isomerization in a membrane reactor. Part I: The synthesis of MFI membranes for the p-xylene separation
(Elsevier Science Sa, 2006-09)
The synthesis and characterization of silicalite and ZSM-5 films supported on porous SS tubes are described. Composite membranes were used to separate xylene isomers between 150 and 400 °C. Permeation measurements of the ...
