Interaction of oxidized copper surfaces with alkanethiols in organic and aqueous solvents. the mechanism of Cu2O reduction
(American Chemical Society, 2010-03)
The interaction of 1-octanethiol, 1,8-octanedithiol, 1-hexadecanethiol, and 16-mercaptohexadecanoic acid with polycrystalline copper surfaces was investigated comparatively using forming solutions with polar (0.05 M NaOH ...
Comparison of arsenate adsorption from neutral pH aqueous solutions using two different iron-trimesate porous solids: Kinetics, equilibrium isotherms, and synchrotron X-ray absorption experiments
(Springer, 2020-10-06)
We have explored the use of two different iron-based porous materials for arsenic uptake from neutral pH aqueous solutions. Both materials are reminiscent of a material known as MIL-100(Fe), a Metal Organic Framework (MOF) ...
Effect of the electrode potential on the surface composition and crystal structure of LiMn2O4 in aqueous solutions
(Pergamon-Elsevier Science Ltd, 2018-04)
Cubic spinel LiMn2O4 has been studied for the reversible extraction of Li+ from natural brine after the application of suitable electrode potentials. In this work we report on the insertion/extraction of Li+ from natural ...
Emulsions of sunflower wax in pectin aqueous solutions: Physical characterization and stability
(Elsevier Science, 2018-06)
The knowledge of the stability and physical properties of film-forming solutions is necessary for optimizing the process design of films. In order to evaluate their applicability for the production of edible films, the ...
Recent advances on elemental biosorption
(Springer Heidelberg, 2019-03)
Industrial activities play a relevant role in environmental pollution since their wastes contain high concentrations of toxic elements that can add significant contamination to natural water and other water sources if no ...
Adsorption of organic pollutants by amine functionalized mesoporous silica in aqueous solution. Effects of pH, ionic strength and some consequences of APTES stability
(Elsevier, 2019-10)
A mesoporous silica with MCM-41 type pore array was synthesized by hydrothermal method and then was functionalized with known amounts of 3-aminopropyltriethoxysilane (APTES) in order to study the selective adsorption towards ...
Practical class to evaluate the adsorption of Al(III) ions from aqueous solutions using non-viable bacterial biomass trapped in an agar-agar matrix
(Taylor & Francis, 2020-01)
The contamination of wastewater with metals and the use of biotechnologies to remove them is commonly discussed in theoretical biology, microbiology and biotechnology classes aimed at undergraduate students. This work ...
Rouse dynamics in PEO-PPO-PEO block-copolymers in aqueous solution as observed through fast field-cycling NMR relaxometry
(Elsevier, 2018-08-15)
We present a proton fast field-cycling (FFC) NMR relaxometry study of the molecular dynamics in three different deuterated water-dispersed triblock copolymers of ethylene oxide (EO) and propylene oxide (PO):EO80PO27EO80(F68), ...
Catalysis Communications “Catalytic wet air oxidation of phenol aqueous solutions by 1% Ru/CeO2-Al2O3 catalysts prepared by different methods
(Elsevier Science, 2006-07-21)
The wet air oxidation of phenol aqueous solutions (5 g/L) has been studied in a trickle bed reactor (140 º and 7 atm of oxygen pressure). The experiments were performed over several 1%Ru/5%CeO2–Al2O3 samples, prepared by ...
Infrared study of trifluoroacetic acid unpurified synthetic peptides in aqueous solution: Trifluoroacetic acid removal and band assignment
(Academic Press Inc Elsevier Science, 2011-03)
Synthetic peptide or protein samples are mostly unpurified with trifluoroacetic acid (TFA) used during the synthesis procedure, which strongly interferes with structure determination by infrared (IR) spectroscopy. The aim ...
