Poly (3,4-ethylene dioxythiophene):poly (styrene sulfonate) (PEDOT:PSS) is a promising conductive polymer to be the next-generation electrode for medical purposes. However, PEDOT:PSS exhibits low conductivity (~1×10−3 S cm−1); hence, incorporating silver nanoparticles (SNP) with will improve electrical conductivity. This paper aims investigate properties differences between doped SNP-based film...

The influence of 0.05% sodium polyanethol sulfonate on the growth of 24 strains of Neisseria meningitidis in broth medium was examined; several of the strains were markedly inhibited. A paper disk method was evolved for screening the sensitivity of various bacteria to sodium polyanethol sulfonate on solid medium; the highest sensitivity was observed in N. meningitidis and Neisseria gonorrhoeae....

A series of perfluorinated compounds (PFCs) including perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA) have been recently measured in a variety of environmental samples and biological matrices. In order to better understand the human exposure routes of these chemicals, levels of PFOS, PFOA, perfluorobutane sulfonate (PFBS), perfluorohexane sulfonate (PFHS) and perfluorooctane ...

In the title sulfonate derivative, C(24)H(26)O(9)S(3), all atoms apart from those of one of the 4-methyl-benzene-sulfonate residues lie approximately in a disc; the dihedral angles between the approximately orthogonal benzene ring and those in the plane are 74.53 (9) and 67.79 (11)°. In the crystal, mol-ecules are consolidated into the three-dimensional architecture by C-H⋯O inter-actions. One ...

The title compound, C4H12N+·C6H6NO3S-·C6H7NO3S, consists of an ion pair and a zwitterionic neutral mol-ecule. The cation adopts an extended conformation [C-C-N-C torsion angles = 177.1 (3) and -178.4 (3)°]. In the crystal, the components are linked by N-H⋯O and N-H⋯N hydrogen bonds, generating a three-dimensional network, which is consolidated by weak C-H⋯O inter-actions.

The specific adsorption of ionomer sulfonate groups on Pt-based catalysts in membrane electrode assemblies (MEAs) has severely restricted Pt catalytic activity, utilization, proton conductivity and mass transport. Here we report a blocking strategy using cyclohexanol to mitigate the detrimental impacts Nafion ionomer. Cyclohexanol with chair or boat conformation blocked path onto surface via co...

BACKGROUND Perfluoroalkyl chemicals, including perfluorooctanoic acid and perfluorooctane sulfonate, are man-made chemicals that have been detected in the blood of over 98% of the US population. Serum uric acid is a novel biomarker, even mild elevations of which has been implicated in the development of hypertension, diabetes mellitus, cardiovascular disease, and chronic kidney disease. We exam...

The bilayer structure of poly(3,4-ethylenedioxythiophene):poly(styrene sulfonate) (PEDOT:PSS) coating on silver nanowires (AgNWs) film is a promising for replacing indium tin oxide (ITO) as flexible transparent conductive electrode. Pristine PEDOT:PSS due to its hydrophilicity and high permeability cannot fully protect AgNWs from mechanical stress oxidation. Here, we present composite approach ...

Perfluorinated compounds have raised concern due to their potential 16 association with detrimental postnatal outcomes in animals and humans. We tested the effects 17 of perfluorooctane sulfonate (PFOS) on a human pluripotent teratocarcinoma (known as 18 NCCIT) cells as an in vitro prototype for developmental toxicity in mammals. NCCIT 19 contains stem-cells able to differentiate into endoderm,...
