M.. And the article was included in Journal of Molecular Liquids in 2022.Name: 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride This article mentions the following:

Three gemini non-ionic surfactant-based polyethylene oxide with variable hydrophobic tails; 8 carbons (GPEOC), 12 carbons (GPEOL), and 16 carbons (GPEOP) have been synthesized successfully. The synthesized gemini surfactant regulated the preparation of the nano-catalyst AgNPs for toxic materials removal. The AgNPs were prepared via photo-chem. reduction reaction based on using the sun light and the gemini surfactants as reducing and capping agents, resp. The surfactant′s tail exhibited a substantial impact on regulating the AgNPs preparation as confirmed by TEM, UV-vis, and DLS measurements. The surfactant GPEOP produced AgNPs with a uniform, dispersibility and smaller particles size 14.8 ± 5.4 nm comparing to other two gemini surfactants GPEOC and GPEOL with shorter hydrophobic tail. The surface and thermodn. performance of the GPEOC, GPEOL and GPEOP gemini non-ionic surfactants were dependent on both solution temperature and surfactant′s tail hydrophobicity. The adsorption ability is significantly improved as functional of temperature or hydrophobicity. Elongation the surfactant′s tail and increasing the temperature, promote lowering the critical micelle concentration and enhance the adsorption affinity at interfaces. The study was extended to investigate how the surfactant′s tail improve the catalytic performance of the AgNPs-based catalyst. The surfactant′s tail controlled the catalytic performance of the AgNPs regarding the methylene blue and p-nitrophenol removal, where the GPEOP/AgNPs exhibited highest catalytic activity. Addnl., the surfactant′s tail controlled the antimicrobial of the prepared surfactant and surfactant/AgNPs hybrid system.

Development of polyester filters with polymer nanocomposite active layer for effective dye filtration was written by Pasichnyk, Mariia;Gaalova, Jana;Minarik, Peter;Vaclavikova, Miroslava;Melnyk, Inna. And the article was included in Scientific Reports in 2022.Product Details of 61-73-4 This article mentions the following:

Organic dyes such as methyl orange (MO) and methylene blue (MB) are widely used in different industries and have become one of the leading emerging water contaminants. The purpose of the current research is to develop new polymer nanocomposite filters for the effective elimination of the dyes, which are non-biodegradable and not efficiently removed by traditional treatment methods. New padded and covered filters were produced applying polystyrene-acrylic/ZnO nanocomposite on the polyester surface by blade coating and one-bath pad methods. Principal results determined by SEM anal. confirm that functionalized layer can create unprecedented function of filter textile material depending on the way of treatment. Due to the modification, the surface area increased from 5.9 for untreated polyester to 85.2 (padded), 44.6 (covered) m²/g. The measured pore size of produced filters is around 3.4 nm, which corresponds to the mesoporous structure. Our study reported effective filters with the rate of MB and MO removal efficiencies up to 60%. Moreover, a colorless reduced form of MB-leuco-methylene blue (LMB) could be created. The functionalized layer of the developed filters through hydrogen bonding between the -OH groups of styrene-acrylic mols. and the -N(CH₃)₂ groups on LMB can stabilize LMB.

Multifunctional coatings with broadband antireflective, durable, photocatalytic, and self-cleaning properties can enhance photovoltaic (PV) power generation by reducing the cleaning frequency and surface light reflection of PV modules. However, such coatings must be cost-effective and maintain their functional integrity under harsh outdoor environmental conditions. In this study, bayberry-like SiO₂ @TiO₂ nanoparticles were prepared by a sol-gel method, and their synthesis procedure and SiO₂/TiO₂ sol volume ratio were optimized based on the refractive index, transmittance distribution, and methylene blue degradation rate. Afterwards, three-layer gradient refractive index broadband antireflective coatings (TGBA) of the optimized SiO₂ @TiO₂ nanoparticles were simulated theor. and systematically characterized by various exptl. techniques. The average transmittance of TGBA-coated glass was 8.93% (380-1800 nm) higher than that of undipped glass, and the photocatalytic performance of TGBA was verified by studying methylene blue photodegradation The self-cleaning performance of TGBA was assessed by outdoor exposure, multi-cycle UV irradiation, and dark storage. The durability of TGBA was evaluated by conducting hardness measurements, abrasion testing, thermal cycling, and damp heat tests. The external quantum efficiency and J-V curves of TGBA-coated PV mini-modules revealed that their short-circuit current densities and power conversion efficiencies were substantially higher than those of undipped modules. The proposed multifunctional coatings can enhance PV power generation in harsh environments.

The presence of antimicrobials, antimicrobial-resistant bacteria (ARB), and the associated antimicrobial resistance genes (ARGs) in the environment is a global health concern. In this study, the concentrations of 25 antimicrobials, the resistance of Escherichia coli (E. coli) strains in response to the selection pressure imposed by 15 antimicrobials, and enrichment of 20 ARGs in E. coli isolated from hospital wastewaters and surface waters were investigated from 2016 to 2018. In hospital wastewaters, clarithromycin was detected at the highest concentration followed by sulfamethoxazole and sulfapyridine. Approx. 80% of the E. coli isolates were resistant, while 14% of the isolates exhibited intermediate resistance against the tested antimicrobial agents. Approx. 61% of the examined isolates were categorized as multidrug-resistant bacteria. The overall abundance of phenotypes that were resistant toward drugs was in the following order: β-lactams, tetracycline, quinolones, sulfamethoxazole/trimethoprim, aminoglycosides, and chloramphenicol. The data showed that the E. coli isolates frequently harbored blaTEM, blaCTX-M, tetA, qnrS, and sul2. These results indicated that personal care products were significantly associated with the presence of several resistant phenotypes and resistance genes, implying their role in co-association with multidrug resistance. Statistical anal. also indicated a disparity specific to the site, treatment, and year in the data describing the prevalence of ARB and ARGs and their release into downstream waters. This study provides novel insights into the abundance of antimicrobial, ARB and ARGs in Sri Lanka, and could further offer invaluable information that can be integrated into global antimicrobial resistance databases.

Abstract: Background: Direct localization of small and deep pulmonary nodules before thoracoscopic surgery using the hookwire or methylene blue techniques has been recently attempted for better surgical outcomes. In this study, we compare the outcomes of the above two techniques. Methods: Two hundred and nineteen patients undergoing 135 hookwire and 151 methylene blue techniques in our University Hospital between July 2020 and Jan. 2022 were compared for localization and hospitalization durations, and the complication risk. Other confounders included patients′ age, gender, localization position, nodules location, count, diameter, and depth. Results: After adjustment of all predictors, the methylene blue technique was associated with a significant 0.6-min (parameter estimate (PE) = -0.568, p value = 0.0173) and an 0.7-day shorter localization and hospitalization time (PE = -0.713, p value = < 0.0001) as compared to using the hookwire technique. The hookwire technique was significantly associated with 5 times the risk of developing a post-localization complication (Adjusted Odds Ratio (Adj OR) = 4.52, 95% CI 1.53-13.33) and 3.6 times the risk of developing a pneumothorax (Adj OR = 3.57, 95% CI 1.1-11.62) as compared to adopting the methylene blue technique. Conclusions: Compared to the hook wire technique, the methylene blue technique offers a shorter procedure and hospitalization stay, as well as a safer post-operative experience.

Endocrine-disrupting chemicals in a typical urbanized bay of Yellow Sea, China: Distribution, risk assessment, and identification of priority pollutants was written by Lu, Shuang;Lin, Chunye;Lei, Kai;Xin, Ming;Wang, Baodong;Ouyang, Wei;Liu, Xitao;He, Mengchang. And the article was included in Environmental Pollution (Oxford, United Kingdom) in 2021.Application of 101-20-2 This article mentions the following:

Endocrine-disrupting chems. (EDCs) in water are receiving particular attention as they pose adverse effects on aquatic systems, even at trace concentrations A comprehensive study was conducted on 14 EDCs (five estrogens and nine household and personal care products (HPCPs)) in the water of the urbanized Jiaozhou Bay in the Yellow Sea during summer and winter. Results showed that the total concentration of 14 EDCs ranged from 100 to 658 ng L^-1 and 56.7-212 ng L^-1 in the estuarine and bay water, resp. The average total concentration of five estrogens in summer was significantly (p < 0.05) lower than that in winter due to the higher precipitation dilution and degradations during summer, whereas the average total concentration of nine HPCPs was significantly (p < 0.05) higher during the summer than during the winter because of the higher usage and emissions during the summer. Estrogens and HPCPs were dominated by 17α-ethinylestradiol and p-hydroxybenzoic acid (PHBA), resp. High PHBA concentrations may be related to the hydrolysis of parabens. The total concentrations of EDCs were higher in the eastern coastal seawater of the bay due to the strong influence of domestic and industrial wastewater discharge. Estrogens may interfere with the endocrine system of aquatic organisms in the bay because the total estradiol equivalent concentration exceeded 1 ng L^-1. 17α-Ethinylestradiol was the main contributor to the estrogenic activity. The EDC mixtures posed high risks (RQ > 1) to mollusks, crustaceans, and fish, and low to moderate risks (RQ < 1) to algae. Fish was the most sensitive aquatic taxon to the EDC mixtures Given the concentration and frequency of EDCs, the optimized risk quotient method revealed that 17α-ethinylestradiol, estrone, triclocarban, triclosan, and 17β-estradiol should be prioritized in ecol. management because of their high risks (prioritization index of >1).

A comparative photophysical study of molecular association of structurally similar phenothiazine dyes in aqueous solutions of caffeine was written by Ghanadzadeh Gilani, A.;Ghary Haghighat, A.. And the article was included in Journal of Molecular Structure in 2022.Computed Properties of C16H18ClN3S This article mentions the following:

This paper comparatively reports the role of a mol. additive (caffeine) on the absorption and emission spectral characteristics and mol. association of a series of phenothiazine dyes in aqueous solutions The studied dyes were five phenothiazine dyes (thionine, azure A, azure B, toluidine blue O, and methylene blue) with strong close mol. structures. The spectral data of the water-caffeine-dye systems were systematically analyzed and discussed based on the chem. structure of the constituent mols. The aggregate structure and the dimer characteristics were analyzed based on the exciton model. The additive was to act as strong water structure-breaker over the range of studied concentration The main driving force for breaking the dye aggregation is water-caffeine or dye-caffeine interactions at low and moderate caffeine contain. At the high additive concentrations, the caffeine-caffeine, dye-dimer caffeine, and caffeine-water-caffeine might have crucial role in the spectral and aggregation behavior of the dyes. Caffeine induces markedly fluorescence quenching in emission spectra of the studied dyes. In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Computed Properties of C16H18ClN3S).

3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen.While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.

Two-dimensional z-type MoS₂/g-C₃N₄ semiconductor heterojunction nanocomposites for industrial methylene blue dye degradation under daylight was written by Sivakumar, S.;Daniel Thangadurai, T.;Manjubaashini, N.;Nataraj, D.. And the article was included in Colloids and Surfaces, A: Physicochemical and Engineering Aspects in 2022.Related Products of 61-73-4 This article mentions the following:

The photocatalytic degradation of textile dyes by graphitic carbon nitrides (g-C₃N₄) under sunlight has received increased attention. Nevertheless, the photocatalytic application of g-C₃N₄ is still limited by its faster charge carrier recombination. To overcome this obstacle, this research has used an impregnation approach to deposit thin-layered molybdenum disulfide (MoS₂) on g-C₃N₄. The crystallinity, morphol., chem. composition, and structural defects of the resulting two-dimensional (2D) z-type MoS₂/g-C₃N₄ semiconductor heterojunction nanocomposite were investigated by XRD, SEM, EDAX, HRTEM, XPS, Raman, and FT-IR techniques. The microscopic images clearly show that (i) g-C₃N₄ is densely covered by MoS₂, and (ii) the g-C₃N₄ and MoS2 interface. Using industrial dye, Methylene Blue (MB), the photocatalytic degradation competency of 5% MoS₂/g-C₃N₄ and 10% MoS₂/g-C₃N₄ nanocomposites was examined under natural sunlight. The homogeneous distribution of the MoS₂ layer on the g-C₃N₄ surface helps significantly to reduce the charge carrier recombination during the photocatalytic process. The Mott-Schottky and impedance measurements demonstrate a more active site for photogenerated electron-hole pair and efficient charge separation for enhanced photocatalytic process, which is consistent with the optical property results. Based on the findings, we confirm that the as-prepared MoS₂/g-C₃N₄ nanocomposites outperformed bare MoS₂ and g-C₃N₄ in terms of MB degradation (100%). In the experiment, the researchers used many compounds, for example, 3,7-Bis(dimethylamino)phenothiazin-5-ium chloride (cas: 61-73-4Related Products of 61-73-4).

Many phenols and parabens are applied in cosmetics, pharmaceuticals and food, to prevent growth of bacteria and fungi. Whether these chems. affect inflammatory diseases like allergies and overweight is largely unexplored. We aimed to assess the associations of use of personal care products with urine biomarkers levels of phenols and paraben exposure, and whether urine levels (reflecting body burden of this chem. exposures) are associated with eczema, rhinitis, asthma, specific IgE and body mass index. Demographics, clin. variables, and self-report of personal care products use along with urine samples were collected concurrently from 496 adults (48% females, median age: 28 years) and 90 adolescents (10-17 years of age) from the RHINESSA study in Bergen, Norway. Urine biomarkers of triclosan (TCS), triclocarban (TCC), parabens and benzophenone-3, bisphenols and dichlorophenols (DCP) were quantified by mass spectrometry. Detection of the urine biomarkers varied according to chem. type and demographics. TCC was detected in 5% of adults and in 45% of adolescents, while Pr (PPB) and Me (MPB) parabens were detected in 95% of adults and in 94% (PPB) and 99% (MPB) of adolescents. Women had higher median urine concentrations of phenolic chems. and reported a higher frequency of use of personal care products than men. Urine concentration of MPB increased in a dose-dependent manner with increased frequency of use of several cosmetic products. Overall, urinary biomarker levels of parabens were lower in those with current eczema. The biomarker concentrations of bisphenol S was higher in participants with pos. specific IgE and females with current asthma, but did not differ by eczema or rhinitis status. MPB, ethylparaben (EPB), 2,4-DCP and TCS were inversely related to BMI in adults; interaction by gender were not significant. Reported frequency of use of personal care products correlated very well with urine biomarker levels of paraben and phenols. Several chems. were inversley related to BMI, and lower levels of parabens was observed for participants with current eczema. There is a need for further studies of health effects of chems. from personal care products, in particular in longitudinally designed studies.

And the article was included in Molecules in 2022.Electric Literature of C13H9Cl3N2O This article mentions the following:

There is a need for rapidly screening thyroid hormone (TH) signaling disruptors in vivo considering the essential role of TH signaling in vertebrates. We aimed to establish a rapid in vivo screening assay using Xenopus laevis based on the T3-induced Xenopus metamorphosis assay we established previously, as well as the Xenopus Eleutheroembryonic Thyroid Assay (XETA). Stage 48 tadpoles were treated with a series of concentrations of T3 in 6-well plates for 24 h and the expression of six TH-response genes was analyzed for choosing a proper T3 concentration Next, bisphenol A (BPA) and tetrabromobisphenol A (TBBPA), two known TH signaling disruptors, were tested for determining the most sensitive TH-response gene, followed by the detection of several suspected TH signaling disruptors. We determined 1 nM as the induction concentration of T3 and thibz expression as the sensitive endpoint for detecting TH signaling disruptors given its highest response to T3, BPA, and TBBPA. And we identified betamipron as a TH signaling agonist, and 2,2,4,4-tetrabromodiphenyl ether (BDE-47) as a TH signaling antagonist. Overall, we developed a multiwell-based assay for rapidly screening TH signaling disruptors using thibz expression as a sensitive endpoint in X. laevis.
