Removal of 241Am from Aqueous Solutions by Adsorption on Sponge Gourd Biochar
(MDPI, 2023)
Luffa cylindrica biomass was converted to biochar and the removal of 241Am by pristine and oxidized biochar fibers was investigated in laboratory and environmental water samples. This species has the added advantage of a ...
Ciprofloxacin conjugated to diphenyltin(iv): a novel formulation with enhanced antimicrobial activity
(Royal Society of Chemistry, 2020-09-07)
The metalloantibiotic of formula Ph2Sn(CIP)2 (CIPTIN) (HCIP = ciprofloxacin) was synthesized by reacting ciprofloxacin hydrochloride (HCIP·HCl) (an antibiotic in clinical use) with diphenyltin dichloride (Ph2SnCl2DPTD). ...
Radionuclide removal from aqueous solutions using Oxidized Carbon Fabrics
(MDPI, 2023)
The adsorption of actinide ions (Am(III) and U(VI)) from aqueous solutions using pristine and oxidized carbon fabrics was investigated by means of batch experiments at different pH values (pH 4, 7 and 9) and temperatures ...
Improving the Cd(ii) detection capability of a new anionic rare earth metal-organic framework based on a [RE6(μ3-OH)8]10+secondary building unit: an ion-exchange approach towards more efficient sensors
(Royal Society of Chemistry, 2020-07-01)
The synthesis and characterization of a new family of rare earth (RE) MOFs based on a hexanuclear (RE3+)6 secondary building unit (SBU) and the angular dicarboxylic ligand 4,4′-oxybisbenzoic acid (H2OBA) with the formula ...
Pine needle–derived biochar adsorbents for removal of Sm(III) and competitive toxic metals from model aqueous matrices
(Elsevier, 2023)
Pine needle–derived biochars have been prepared and investigated as adsorbent materials for the removal of trivalent samarium (Sm(III)) from aqueous systems. The biochars, which were previously oxidized and magnetized), ...
Characterization of spun PMMA/UiO-66-NH2@PMMA thin films and their SPR sensing response to haloalkane vapors
(IEEE Sensors Council, 2022-10-01)
Immobilization of metal-organic framework (MOF) particles onto a gold substrate using spin coating is a difficult task due to the lack of cohesion forces between the crystals and the substrate. Therefore, it was decided ...
Dynamic covalent amphiphilic polymer conetworks based on end-linked pluronic F108: preparation, characterization, and evaluation as matrices for gel polymer electrolytes
(American Chemical Society, 2024-04-26)
We present the development of a platform of well-defined, dynamic covalent amphiphilic polymer conetworks (APCN) based on an α,ω-dibenzaldehyde end-functionalized linear amphiphilic poly(ethylene glycol)-b-poly(propylene ...
Mixed-valence manganese carboxylate clusters, {MnIII6MnII4}, {MnIII7MnII5Na}, and {MnIII7MnII5}, derived from the combined use of Di-2-pyridyl ketone with selected aliphatic diols

Abstract
Three new polynuclear clusters with the formulae [Mn10O4(OH)(OMe){(py)2C(O)2}2{(py)2C(OMe)(O)}4(MeCO2)6](ClO4)2 ...
Catalysis of a Diels–Alder Reaction between Azachalcones and Cyclopentadiene by a Recyclable Copper(II)-PEIP Metal-Organic Framework
(Multidisciplinary Digital Publishing Institute (MDPI), 2023-08-01)
Metal-organic frameworks (MOFs) have attracted considerable interest as emerging heterogeneous catalysts for organic transformations of synthetic utility. Herein, a Lewis-acidic MOF, {[Cu3(PEIP)2(5-NH2-mBDC)(DMF)]·7DMF}∞, ...
Highlighting the structure – directing capability of the functional groups of angular dicarboxylic ligands: New 2-dimensional Cu2+ MOFs from analogous synthetic routes
(Elsevier, 2021-09-01)
The reaction of Cu(NO3)2·2.5H2O with the angular dicarboxylic ligands 4,4′-oxybis(benzoic acid) (H2OBA), or 4,4′-(hexafluoroisopropylidene)bis(benzoic acid)) (H2HFPBBA), or 4,4′-sulfonyldibenzoic acid (H2SDBA) in a ~1/2 ...
