On December 15, 2020, Muz, Melis; Escher, Beate I.; Jahnke, Annika published an article.Synthetic Route of 80-07-9 The title of the article was Bioavailable environmental pollutant patterns in sediments from passive equilibrium sampling. And the article contained the following:

Sediment-associated risks depend on the bioavailable fraction of organic chems. and cannot be comprehended by their total concentrations The present study investigated contamination patterns of bioavailable chems. in sediments from various sites around the globe by using passive equilibrium sampling. The extracts had been characterized previously for mixture effects by in vitro reporter gene assays and were in this study analyzed using gas chromatog.-high resolution mass spectrometry for 121 chems. including both legacy and emerging contaminants. The spatial distribution of the detected chems. revealed distinct contamination patterns among sampling sites. We identified compounds in common at the different sites but most contaminant mixtures were site-specific. The mixture effects of the detected chems. were predicted with a mixture toxicity model from effect concentrations of bioactive single chems. and detected concentrations, applying a joint model for concentration addition and independent action. The predicted mixture effects were dominated by polycyclic aromatic hydrocarbons, and among the chems. with available effect data, 17% elicited oxidative stress response and 18% activated the arylhydrocarbon receptor. Except for two sites in Sweden, where 11 and 38% of the observed oxidative stress response were explained by the detected chems., less than 10% of effects in both biol. end points were explained. These results provide a comprehensive investigation of bioavailable contamination patterns of sediments and may serve as an example of employing passive equilibrium sampling as a monitoring technique to integrate the risk of bioavailable sediment-associated chems. in aquatic environments. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Synthetic Route of 80-07-9

Kodama, Susumu; Yoshii, Nao; Ota, Akihiro; Takeshita, Jun-ichi; Yoshinari, Kouichi; Ono, Atsushi published an article in 2021, the title of the article was Association between in vitro nuclear receptor-activating profiles of chemical compounds and their in vivo hepatotoxicity in rats.Recommanded Product: 80-07-9 And the article contains the following content:

The liver plays critical roles to maintain homeostasis of living organisms and is also a major target organ of chem. toxicity. Meanwhile, nuclear receptors (NRs) are known to regulate major liver functions and also as a critical target for hepatotoxic compounds In this study, we established mammalian one-hybrid assay systems for five rat-derived NRs, namely PXR, PPARα, LXRα, FXR and RXRα, and evaluated a total of 326 compounds for their NR-activating profiles. Then, we assessed the association between their NR-activating profile and hepatotoxic endpoints in repeated-dose toxicity data of male rats from Hazard Evaluation Support System. In the in vitro cell-based assays, 68, 38, 20, 17 and 17 compounds were identified as positives for PXR, PPARα, LXRα, FXR and RXRα, resp. The association analyses demonstrated that the PXR-pos. compounds showed high frequency of endpoints related to liver hypertrophy, such as centrilobular hepatocellular hypertrophy, suggesting that PXR activation is involved in chem.-induced liver hypertrophy in rats. It is intriguing to note that the PXR-pos. compounds also showed statistically significant associations with both prolonged activated partial thromboplastin time and prolonged prothrombin time, suggesting a possible involvement of PXR in the regulation of blood clotting factors. Collectively, our approach may be useful for discovering new functions of NRs as well as understanding the complex mechanism for hepatotoxicity caused by chem. compounds The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Recommanded Product: 80-07-9

And the article contained the following:

In this work, a series of fluorene-containing fluorinated polyethersulfone (PES-6AF/BHPF) copolymers with high temperature resistance and intrinsic low dielec. constant (low-ε) have been designed and synthesized from 4,4′-dichlorophenyl sulfone (DCS) and polyphenol. The performance of obtained PES-6AF/BHPF can be controlled and optimized by controlling the copolymers structure. The thermal and dielec. properties of PES-6AF/BHPF were evaluated comprehensively. The obtained PES-6AF/BHPF copolymers show high glass transition temperatures (Tg) ranging from 200 to 260 °C, and 5% weight loss temperatures (Td5%) is stable up to 500 °C. The ε value of PES-6AF/BHPF-0% and PES-6AF/BHPF-100% are as low as 2.1 and 2.3, and the loss tangent (tan δ) are only 0.0088 and 0.003 at 1 kHz, resp. In addition, all of PES-6AF/BHPF films show good stability of dielec. properties in high temperature conditions. More importantly, the PES-6AF/BHPF copolymers are soluble in common solvents (such as DMAc, NMP, DMF, THF). The PES-6AF/BHPF copolymers are amorphous and can be easily cast into transparent and flexible films with tensile strength of 62-74 MPa and an elongation at break of 13.3-15.8%. The outstanding comprehensive properties made it possible to be the most promising polymer candidates for high-performance interlayer dielecs.

And the article contained the following:

A novel sulfonated polyvinyl alc. containing alkynyl groups (SPVA-CC) and a new sulfonated poly (aryl ether ketone sulfone) (SPAEKS) are synthesized. Semi-crosslinked membrane (semi-crosslink-SPAEKS-x) was prepared by click reaction of mercapto-alkynes between 1, 5-pentanedithiol and SPVA-CC. The chem. structures of SPAEKS, SPVA-CC and semi-crosslink-SPAEKS-x are confirmed by 1H-NMR and FTIR spectra. The semi-crosslink-SPAEKS-x membranes show good mech. properties, excellent dimensional stability and oxidative stability. The proton conductivity of SPAEKS and semi-crosslink-SPAEKS-x membranes is in the range of 25.6-52.5 mS/cm. The methanol permeability of semi-crosslink-SPAEKS-x membranes is in the range of 1.4-1.7 x 10-7 cm-2 s-1, which is much lower than that of Nafion 117 membrane (18.3 x 10-7 cm-2 s-1). Especially, the proton selectivity of semi-crosslink-SPAEKS-15 membrane (24.3 x 104 S s cm-3) is above seven times higher than that of Nafion 117 membrane (3.4 x 104 S s cm-3).

And the article contained the following:

The synthetic chems. in food contact materials can migrate into food and endanger human health. In this study, the traveling wave collision cross section in nitrogen values of more than 400 chems. in food contact materials were exptl. derived by traveling wave ion mobility spectrometry. A support vector machine-based collision cross section (CCS) prediction model was developed based on CCS values of food contact chems. and a series of mol. descriptors. More than 92% of protonated and 81% of sodiated adducts showed a relative deviation below 5%. Median relative errors for protonated and sodiated mols. were 1.50 and 1.82%, resp. The model was then applied to the structural annotation of oligomers migrating from polyamide adhesives. The identification confidence of 11 oligomers was improved by the direct comparison of the exptl. data with the predicted CCS values. Finally, the challenges and opportunities of current machine-learning models on CCS prediction were also discussed.

Phifer, Adrienne; Gray, George; Kratchman, Jessica; Attene-Ramos, Matias S. published an article in 2021, the title of the article was Assessing how in vitro assay types predict in vivo toxicology data.Application In Synthesis of 4,4′-Sulfonylbis(chlorobenzene) And the article contains the following content:

In vivo animal bioassays are increasingly being supplemented with in vitro assays to serve as the new standard for chem. toxicity tests. Despite this shift, investigators face challenges related to increased reliance on in vitro data. The aim of this study was to deploy a streamlined method to assess the ability of in vitro data to predict similar results as in vivo data by correlating chem. toxicity rankings obtained using Benchmark Doses and Benchmark Dose Lower Limits (BMD(L)s) derived from in vivo and in vitro assays. In vitro and in vivo assay characteristics were assessed for their impact on the predictive ability of in vitro data. Min. best-fit BMD(L)s were calculated for chems. using Environmental Protection Agency′s (EPA′s) Benchmark Dose Software (BMDS). Forty-one chems. met the inclusion criteria of this study. Relative chem. toxicity rankings were assessed through Kappa statistics, Pearson correlations, and/or Ordinary Least Squares (OLS) regressions. Results illustrated likely ability of in vitro data to predict similar results as short-term in vivo data. Further, rankings derived from in vitro cytotoxicity assays, unlike stress response assays, significantly correlated with rankings derived from short-term in vivo assays. These results support the use of in vitro data as a prioritization tool within toxicity testing.

Kim, Jun Ha; Vinothkannan, Mohanraj; Kim, Ae Rhan; Yoo, Dong Jin published an article in 2020, the title of the article was Anion exchange membranes obtained from poly(arylene ether sulfone) block copolymers comprising hydrophilic and hydrophobic segments.SDS of cas: 80-07-9 And the article contains the following content:

The anion exchange membrane may have different phys. and chem. properties, electrochem. performance and mech. stability depending upon the monomer structure, hydrophilicity and hydrophobic repeating unit, surface form and degree of substitution of functional groups. In current work, poly(arylene ether sulfone) (PAES) block copolymer was created and used as the main chain. After controlling the amount of NBS, the degree of bromination (DB) was changed in Br-PAES. Following that, quaternized PAES (Q-PAES) was synthesized through quaternization. Q-PAES showed a tendency of enhancing water content, expansion rate, ion exchange capacity (IEC) as the degree of substitution of functional groups increased. However, it was confirmed that tensile strength and dimensional properties of membrane reduced while swelling degree was increased. In addition, phase separation of membrane was identified by at. force microscope (AFM) image, while ionic conductivity is greatly affected by phase separation The Q-PAES membrane demonstrated a reasonable power output of around 64 mW/cm2 while employed as electrolyte in fuel cell operation.

And the article contained the following:

The present paper describes the design and evaluation of novel hydrophilic-hydrophobic poly(arylene ether sulfone) (PAES) multiblock copolymers for their synergistic effects upon transport properties and their potential use in proton exchange membrane water electrolysis. The multiblock copolymers are prepared via a coupling reaction between (i) a hydrophilic segment consisting of a disulfonated quinone fluorinated biphenyl group that contains fluorine moieties next to the sulfonated groups to increase the acidity, and (ii) hydrophobic segments composed of non-sulfonated biphenyl sulfone to provide dimensional stability. Two different lengths (mol. weights; 5 k and 10 k, where k represents 103 g mol-1) of hydrophobic segments are used to investigate the effects of the membrane properties compared with those of Nafion and PAES random copolymer (i.e., BPSH40). Atomic force microscopy images of the BPSH40 and multiblock membranes are shown to agree closely with a mesoscale simulation, thus confirming the importance of the morphol. effect upon the transport properties. Moreover, the multiblock copolymer with a higher proportion of hydrophilic segments (10 k-5k) was shown to provide enhanced performance (3.41 A cm-2 at 1.9 V) compared to the multiblock copolymer with equal proportions of hydrophilic and hydrophobic segments (10 k-10 k) due to the greater continuity of nano-sized ionic channels. The experimental process involved the reaction of 4,4′-Sulfonylbis(chlorobenzene)(cas: 80-07-9).Related Products of 80-07-9

And the article contained the following:

Hydrocarbon-based membranes can extend the operating current range of a polymer electrolyte membrane water electrolyzer (PEMWE) because of their low gas permeability and high proton conductivity However, increasing the ion exchange capacity for sufficiently high proton conductivity leads to poor mech. stability and increased gas permeability for hydrocarbon-based membranes. This study presents a poly(p-phenylene)-based multiblock polymer with an oligomeric chain extender (CE-sPP-PPES) for improved mech. stability and extended operating current range. With the introduction of a chain extender, the mech. and chem. stability were notably enhanced. The effects of ion exchange capacity on mech. properties, proton conductivity, and hydrogen crossover were investigated compared to a Nafion membrane. The CE-sPP-PPES-based PEMWE has a 2.1 times wider operating current range than a Nafion-based PEMWE because of its smaller ohmic overvoltage and lower gas crossover at an optimal ion exchange capacity, demonstrating the possibility of a new hydrocarbon-based membrane for PEMWE.
