Journal ArticleDOI
Wettability alteration of carbonate rocks by surfactants: A mechanistic study
TL;DR: In this article, an extensive mechanistic study was performed utilizing different analytical tools to study the effects of surfactants on the sample rock's wettability, and the results indicated that the surfactant act in different manners according to their structure.
Journal ArticleDOI
Sulfonic acid supported on hydroxyapatite-encapsulated-γ-Fe2O3 nanocrystallites as a magnetically Brønsted acid for N-formylation of amines
TL;DR: The magnetically catalytic system was recovered by-passing time consuming filtration operation by using an external magnet device as discussed by the authors, which also enhances product purity and promises economic as well as environmental benefits.
Journal ArticleDOI
Sulfamic acid heterogenized on hydroxyapatite-encapsulated γ-Fe2O3 nanoparticles as a magnetic green interphase catalyst
TL;DR: In this article, a green system for chemical synthesis is introduced, which is based on magnetic nanoparticle-supported propylsulfamic acid deposited onto hydroxyapatite [γ-Fe2O3-HAp-(CH2)3-NHSO3H] synthesized as a unique heterogeneous acid catalyst.
Journal ArticleDOI
Nanomagnetically modified sulfuric acid (γ-Fe2O3@SiO2-OSO3H): an efficient, fast, and reusable green catalyst for the Ugi-like Groebke-Blackburn-Bienaymé three-component reaction under solvent-free conditions
TL;DR: In this paper, superparamagnetic nanoparticles of modified sulfuric acid (γ-Fe2O3@SiO2-OSO3H) represent a straightforward and green catalyst for the rapid synthesis of aminoimidazopyridine skeletons via the Groebke-Blackburn-Bienayme three-component reaction.
Journal ArticleDOI
Experimental study of the removal of copper ions using hydrogels of xanthan, 2-acrylamido-2-methyl-1-propane sulfonic acid, montmorillonite: Kinetic and equilibrium study.
TL;DR: Removal of copper ions from aqueous solution using novel xanthan gum (XG) hydrogel and xantha gum-graft- 2-acrylamido-2-methyl-1-propane sulfonic acid/montmorillonite hydrogels and adsorption process was found to follow Langmuir isotherm model, fitted well with pseudo second order model.
