Modification of Activated Carbon for the Adsorption of Humic Acid
(SAGE Publications, 2015-02-01)
Highly selective acetalization of glycerol with acetone to solketal over acidic carbon-based catalysts from biodiesel waste
(Elsevier Sci Ltd, 2016)
The glycerol acetalization reaction in the presence of acetone was evaluated using acidic carbon-based catalysts from biodiesel waste as catalysts. Acidic carbon-based catalysts were prepared with different glycerin: ...
Highly selective determination of dopamine in the presence of ascorbic acid and serotonin at glassy carbon electrodes modified with carbon nanotubes dispersed in polyethylenimine
(American Scientific Publishers, 2008-11)
We report the highly selective and sensitive voltammetric dopamine quantification in the presence of ascorbic acid and serotonin by using glassy carbon electrodes modified with a dispersion of multiwall carbon nanotubes ...
Mesoporous activated carbon from sunflower shells modified with sulfonic acid groups as solid acid catalyst for itaconic acid esterification
(Elsevier Science, 2021-07)
Mesoporous activated carbon from sunflower shells (SAC) modified with sulfonic acid groups (SACSO3H-XX) was synthesized by grafting the sulfonic groups on the carbon surface to produce novel heterogeneous and reusable solid ...
Understanding the acid dissolution of Serpentinites (Tailings and waste rock) for use in indirect mineral carbonation
(2022-04-01)
Solid carbonates can be formed by indirect mineral carbonation using the pH swing method for CO2 storage. It occurs at low temperatures and pressures in four stages: acid dissolution, purification, carbonation, and recovery. ...
UNUSUAL MORPHOLOGY OF CALCIUM CARBONATE CONTROLLED BY AMINO ACIDS IN AGAROSE GEL
(Sociedad Chilena de Química, 2010)
Solubility Of Protocatechuic Acid, Sinapic Acid And Chrysin In Supercritical Carbon Dioxide
(ELSEVIER SCIENCE BVAMSTERDAM, 2016)
Effect of an acid diet allied to sonic toothbrushing on root dentin permeability: An in vitro study
(2010-12-01)
This study quantified alterations in root dentin permeability after exposure to different acid beverages. Twenty-five third molars were sectioned below the cementoenamel junction, the root segment was collected, and the ...
