Journal ArticleDOI
Selective transport of metal ions across polymer inclusion membranes (PIMs) containing calix[4]resorcinarenes
TL;DR: In this article, the use of polymer inclusion membranes (PIMs) for selective and efficient transport of metal ions is increasingly retaining attention, and the authors applied them for the investigation of facilitated transport of Zn(II), Cd(II, and Pb(II) ions from aqueous nitrate source phase.
Journal ArticleDOI
Preparation, characterization and thermal studies of polymer inclusion cellulose acetate membrane with calix[4]resorcinarenes as carriers
TL;DR: In this paper, a polymer inclusion membrane (PIM) system with cellulose acetate polymer as support and calix[4]resorcinarenes as carriers has been developed.
Journal ArticleDOI
Recyclable Keggin Heteropolyacids as an Environmentally Benign Catalyst for the Synthesis of New 2-Benzoylamino-N-phenyl-benzamide Derivatives under Microwave Irradiations at Solvent-Free Conditions and the Evaluation of Biological Activity
Karima Ighilahriz-Boubchir,Baya Boutemeur-Kheddis,Chérifa Rabia,Malika Makhloufi-Chebli,Maamar Hamdi,Artur M. S. Silva +5 more
TL;DR: It is found that the use of H3PW12O40·13H2O acid coupled to microwave irradiation allowed obtaining a high-yielding reaction with a short time.
Journal ArticleDOI
Synthesis and optical properties of coumarins and iminocoumarins: Estimation of ground- and excited-state dipole moments from a solvatochromic shift and theoretical methods
Amal Rabahi,Malika Makhloufi-Chebli,Safouane M. Hamdi,Artur M. S. Silva,Djaffar Kheffache,Baya Boutemeur-Kheddis,Maamar Hamdi +6 more
TL;DR: In this paper, the optical properties of coumarin and iminocoumarin were investigated in different solvents by UV/vis absorption and fluorescence spectroscopy at room temperature (298 K).
Journal ArticleDOI
Keggin and Dawson-type polyoxometalates as efficient catalysts for the synthesis of 3,4-dihydropyrimidinones: experimental and theoretical studies
Liza Saher,Malika Makhloufi-Chebli,Leila Dermeche,Baya Boutemeur-Khedis,Chérifa Rabia,Artur M. S. Silva,Maamar Hamdi +6 more
TL;DR: In this paper, 3,4-Dihydropyrimidinones were synthesized by a multicomponent condensation of an aldehyde, a β-keto ester, and urea, in acetonitrile and ethanol using Keggin and Dawson type polyoxometalates as catalysts.
