The organic anion of the title compound, {[Na(C(15)H(9)O(10)S)(H(2)O)(2)]·H(2)O}(n) {systematic name: poly[[diaqua-[μ-2-(3,4-dihy-droxy-phen-yl)-3,5,7-trihy-droxy-4-oxo-4H-chromene-8-sulfon-ato]-sodium] monohydrate]}, has a nearly planar structure. The Na atom is six-coordinated by O atoms, two from water mol-ecules and four from the anion. The dihedral angle between the ring systems in the ani...

Perfluorooctane sulfonate (PFOS) is under increased scrutiny asanenvironmentalpollutantduetorecentreportsof itsworldwide distribution, environmental persistence, and bioaccumulation potential. The susceptibility of technical PFOS and PFOS branched isomers to chemical reductive dehalogenation with vitamin B12 (260 μM) as catalyst and Ti(III)-citrate (36 mM) as bulk reductant in anoxic aqueous so...

Abstract The current study presents a new class of functional derivatives ( 1–3 ) consisting dicationic viologen (4,4’-bipyridinium unit) V 2+ capped by nucleobases thymine NB 1 ), adenine 2 thymine/adenine , and ion-paired with amphiphilic anion 3,4,5-tris(dodecyloxy)benzene sulfonate DOBS − ). target our work focuses on the design synthesis molecular building blocks in which three different f...

This research aimed to study the effects of individual components on physicochemical properties systems composed surfactants, polymers, oils, and electrolytes in order maximize recovery efficiency kerosene while minimizing impact environment human health. Four independent factors, namely anionic surfactant sodium dodecylbenzene sulfonate (X1) (SDBS), oil (X2) (kerosene), water-soluble polymer p...

Abstract This work focuses on the improvement of electrospinnability low-sulfonate lignin (LSL)/polyvinylpyrrolidone (PVP) solutions by addition surfactants (SDS, CTAB and Tween-20) as well ability resulting nanofibers to structure castor oil. Solutions with two LSL/PVP weight ratios (70:30 90:10) in DMF were prepared adding variable surfactant concentrations (0–1 wt.%), physicochemically chara...

Abstract Our scope is synthesis a new poly fluorobenzamide oxime ester and study its structural, optical, dielectric properties. Consequently, (( E )-2-((acryloyloxy)imino)- N -(4-fluorophenyl) acetamide) ( AIFPA ) was as-synthesized via condensation reaction of )- -(4-fluorophenyl)-2-(hydroxyimino) acetamide with acrylic acid to polymerize it free radical polymerization PAIFPA ). over above, t...

Due to its biocompatibility, electrical conductivity, and tissue-like elasticity, poly(3,4-ethylenedioxythiophene):polystyrene sulfonate (PEDOT:PSS) constitutes a highly promising material regarding the fabrication of smart cell culture substrates. However, until now, high-throughput synthesis pure PEDOT:PSS geometries was restricted flat sheets fibers. In this publication, first microfluidic p...

Abstract The solution casting process was used to fabricate nanocomposite samples composed of carboxymethylcellulose (CMC), polyvinyl alcohol (PVA), poly(3,4-ethylenedioxythiophene) polystyrene sulfonate (PEDOT:PSS) and filled with varied concentrations nickel oxide nanoparticles (NiO NPs). effect NiO on the structural, optical, electrical properties pure CMC/PVA/PEDOT:PSS mixture studied discu...

The use of polyethersulfone (PES), an excellent but highly hydrophobic thermoplastic, as a matrix material for ionexchange membranes was investigated. To make PES ion-exchangeable, sulfonate groups were introduced to the polymer chains by sulfonation reaction with chlorosulfonic acid. The degree of sulfonation of sPES was estimated to be 21%. Preliminary experiments investigated the effect of p...

A series of radiation-grafted alkaline anion-exchange membranes (AAEMs) with degrees of grafting (by mass) in the range 20 – 26% were produced and characterised. Conductivities (from impedance spectroscopy) up to 0.023 ± 0.001 S cm at 50 ± 1°C were demonstrated, which are between 20 – 50% of values for the commercial acidform membrane Nafion-115 (σ = 0.045 ± 0.004 (65°C) – 0.104 ± 0.008 (50 ± 1...
