Keywords: chitosan microsphere corrosion sensing. We’ll tell you more about this compound (cas:76-60-8).

Chitosan microspheres containing bromocresol green, cresol red, and phenolphthalein for corrosion detection, through pH change, are synthesized in order to be used in protective coatings for aluminum alloys. Microspheres containing corrosion detection species are characterized morphol. (SEM) and physico-chem. (FTIR, TGA). Release studies (UV-vis) are performed in corrosion-promoting conditions (pH, NaCl), and detection studies by immersion in media associated with corrosion activity while microspheres’ sensing activity is evaluated visually. Electrochem. characterization of AA2024 substrates in the presence of chitosan spheres is performed to understand material performance, and a color change is observed as a result of local pH increase in cathodic areas when corrosion takes place. These findings can be correlated with the results from release studies and seem a promising approach for corrosion sensing purposes, not only because pH increase is possible to detect due to corrosion, but also because chitosan is considered an environmentally friendly material.

In this study, a novel coral-like Fe2O3/Mn2O3 nanocomposite (FMNC) was synthesized by a one-step surfactant-mediated co-precipitation method. The application of this material was demonstrated for the degradation of organic dyes. The crystallog. anal. of FMNC confirmed the presence of α-Fe2O3 and α-Mn2O3 with no impurity of MnFe2O4. The photocatalyst showed strong absorbance in the UV and Visible range with a low bandgap energy of 1.11 eV. In the optimized exptl. conditions (0.5 g L-1 photocatalyst, 10 mg L-1 MB concentration, and 5 mmol L-1 H2O2), the FMNC photocatalyst showed 80-97% degradation of organic dyes within 75 s using low power UV-C irradiation Moreover, scavenger studies confirmed the involvement of ·OH radicals and holes as the main active species responsible for the dye degradation process. The photocatalytic degradation process was insignificantly affected by the presence of inorganic anions. The photocatalyst showed a ∼ 5% loss of performance after seven photocatalytic cycles. This study concluded that UV/H2O2/FMNC system is a fast, efficient, and economical approach for remediation of dye-contaminated wastewater.

Abstract: The anthropogenic carbon dioxide (CO2) denseness in the earth’s atm. is increasing day-to-day by combusting fossil fuels for power generation. And, it is the most important greenhouse gas (GHG) responsible for 64% of global warming. Solvent-based carbon capture gained more attention towards researchers because of its easiness to integrate with the coal-fired power plant without significant modifications. During CO2 absorption, the phys. property of the solvent gets changed. A change in the solvent’s physicochem. property affects further CO2 absorption, thereby increasing the carbon-capture energy demand. The present exptl. study encompasses CO2 absorption studies using 30 wt% aqueous monoethanolamine (MEA), 2-amino-2-methyl-1-propanol (AMP) and piperazine (PZ) followed by the detailed anal. of physicochem. properties (pH, carbon loading (α), viscosity (μ), d. (ρ) and surface tension (σ)) of various CO2-loaded solutions The results revealed that these properties are exhibiting interdependent eccentrics. Furthermore, an empirical model was developed to predict the carbon loading of the tested solvents. This model includes the tested physicochem. properties, reaction mixture temperature, diffusivity and change in the mass of solvent during carbon loading. In addition, an empirical model for viscosity as a function of temperature, carbon loading and mol. weight of solvents was developed.

Keywords: zinc europium terbium tetrazolyl isophthalate MOF preparation crystal structure; thermal stability zinc europium terbium tetrazolyl isophthalate MOF; adsorption luminescence zinc europium terbium tetrazolyl isophthalate MOF; fluorescent probe zinc europium terbium tetrazolyl isophthalate MOF.They researched the compound: 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide( cas:76-60-8 ).Application of 76-60-8. Aromatic heterocyclic compounds can be divided into two categories: single heterocyclic and fused heterocyclic. In addition, there is a lot of other information about this compound (cas:76-60-8) here.

A new family of isostructural 3d -4f heterometallic metal-organic frameworks (HMOFs), [Zn3EuxTb2-x(TZI)4(DMA)5(H2O)3]·4DMA [x = 0(1), 0.3(2), 0.6(3), 0.9(4), 1(5), 1.2(6), 1.5(7), 1.8(8), 2(9)], was synthesized using the 5-(4-(tetrazol-5-yl)phenyl)isophthalic acid (H3TZI) ligand, LnIII ions and ZnII ions under solvothermal conditions. All HMOFs exhibit a (3,3,4,5,5)-connected 63·63(42·62·82)(4.65·8)(4.66·83) topol., which features three different types of motifs: one is a mononuclear ZnII ion and the other two motifs are binuclear [Zn(COO)3Ln] clusters. The adsorption experiments indicate that Zn3Tb2 (1) could efficiently remove almost all I2 from cyclohexane solution after 12 h and also showed better adsorption towards neutral red (NR) dye (adsorption: only the Zn3Tb2 (1) was taken as one representative). Simultaneously, the luminescence sensing showed that Zn3Tb2 (1) and Zn3Eu2 (9) have excellent response and sensitivity towards pollutants such as Fe3+ ions and 2,4,6-trinitrophenol (TNP) with high selectivity and a fairly low limit of detection through luminescence quenching effect. Moreover, seven trimetallic-doped HMOFs 2-8 analogs of Zn3Ln2 (single) HMOFs were designed and prepared, showing different changes of luminescent color. More interestingly, Zn3Eu1.5Tb0.5 (7) with white-light emission was fabricated by doping relative concentrations of Eu3+ and Tb3+ ions. To the best of the authors’ knowledge, Zn3Eu1.5Tb0.5 (7) represents a novel kind of heterometallic Zn3Ln2 HMOFs with white-light emission. It could be deduced that the excellent characteristics, namely strong typical luminescence emission of ZnII and LnIII ions, microporous channels, active open metal sites (tetracoordinated ZnII-metal sites), and uncoordinated carboxylate O atoms and uncoordinated tetrazolate N atoms, made the above HMOFs an ideal platform for adsorption, luminescence sensing, and white-light emission. More significantly, these HMOFs are the first reported Zn-Ln heterometallic materials with the H3TZI ligand.

In order to rapidly characterize the free-base nicotine (FBN) in e-liquids, two indicators, bromocresol green (BCG) and chlorophenol red (CPR), which could provoke color reactions with FBN, were employed to develop a spectroscopic method for FBN quantification in e-liquids The developed method was compared with the pH method and the NMR method. The results showed that the two color indicators were weakly acidic and could bind with FBN but not with protonated nicotine, thus indicating the mass fraction of FBN. The correlations between the spectroscopic responses and the mass fraction of FBN in e-liquids were established based on this principle. The calibration curve was lgA616 = 0.0172c – 0.5378 (r2 = 0.9989, LOD = 0.11 mg/g, LOQ = 0.37 mg/g) when adopting BCG, while the calibration curve for CPR was lgA587 = 0.0154c – 0.8130 (r2 = 0.9936, LOD = 0.19 mg/g, LOQ = 0.63 mg/g). Sixteen com. e-liquid samples were tested using the developed method. The average proportion of FBN (αfbn) in e-liquids was 19.2% for the e-liquids with higher than 20 mg/g nicotine and 76.1% for those with lower than 20 mg/g nicotine. In addition, the mass fractions of FBN obtained by this method were higher than those by the pH method when αfbn was lower. There was a good correlation between the FBN mass fractions obtained by the spectroscopic method and by the NMR method. As an indicator, CPR was better than BCG. The spectrometry method can realize the rapid and visual determination of FBN in e-liquids

To evaluate the impact of upper tract urothelial carcinoma (UTUC) on bacillus Calmette-Guerin (BCG) response and progression in patients with non-muscle-invasive bladder cancer (NMIBC). We performed an institutional review board-approved review of patients with NMIBC treated with adequate intravesical BCG, as defined by the US Food and Drug Administration, at our institution between 2000 and 2018. Patients were stratified by presence of any UTUC and time of UTUC diagnosis (preceding vs synchronous to NMIBC diagnosis or metachronous disease after NMIBC diagnosis). Descriptive statistics were used to summarize the data overall and by groups, and t-tests or Wilcoxon’s rank sum tests and Pearson’s chi-squared or Fisher’s exact tests were used to analyze continuous and categorical data, resp. Of 541 patients with NMIBC treated with adequate BCG, 59 (10.9%) were diagnosed with UTUC. Of these, 34 had a history of UTUC prior to NMIBC (UTUC-P; median [interquartile range {IQR}] 13.1 [7.4-27.6] months prior), while 25 developed UTUC after diagnosis of NMIBC (six synchronous and 19 metachronous; median [IQR] 12.1 [1.7-28.1] months after). Compared to the non-UTUC group, patients with UTUC-P were more likely to exhibit Tis without papillary tumor in the bladder (20.6% vs 5.0%; P < 0.001), but were less likely to have T1 disease on index transurethral resection (8.8% vs 49.4%; P < 0.001). Patients with UTUC-P developed more recurrences (55.9% vs 34.0%; P = 0.010), any stage/grade progression (23.5% vs 9.8%; P = 0.012) and progression to muscle-invasive or metastatic disease (17.6% vs 6.4%; P = 0.014). The presence of high-grade UTUC-P compared to low-grade UTUC-P was associated with increased NMIBC recurrence (68.2% vs 25.0%; P = 0.049). There was no significant difference in rates of recurrence or progression based on timing of UTUC with respect to the index bladder tumor, although this anal. was limited by small numbers Presence of UTUC prior to a diagnosis of NMIBC was associated with an almost twofold increased recurrence and progression rates after adequate BCG therapy. This should be considered when counselling patients and designing cohorts for clin. trials.

The ability to program sol-gel transition in time is key for living organisms to maintain their vital functions and to grow complex materials. Replicating this behavior with synthetic chem. networks is challenging, but highly rewarding for the design of intelligent biomimetic materials. Thanks to a combination of autocatalysis and supramol. complexation, the iodate-hydroxymethanesulfinate-poly(vinyl alc.) system features the emergence of self-propagating gelation fronts, stable or transient depending on the fine-tuning of the system.

Synthetic Route of C21H14Br4O5S. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide, is researched, Molecular C21H14Br4O5S, CAS is 76-60-8, about The Apoptosis Mechanism of Epirubicin Combined with BCG on Human Bladder Cancer Cells.

The purpose of our study was to explore the combination effect of epirubicin and Bacillus Calmette Guerin (BCG) and its mechanism. Bladder cancer is a threat to human health worldwide. Commonly used chemotherapy drugs and biotherapy have significant therapeutic effects on bladder cancer, but the mechanism and combined effects are still unclear. To evaluate the anti-cancer effect of epirubicin combined with BCG on human bladder cancer cells, our studies were carried out. The viability of human bladder cancer cells with epirubicin and/or BCG treatments was examined by Cell Counting Kit-8 (CCK-8) assay. Apoptosis and cell cycle phase were determined by flow cytometry anal. Pre-apoptosis factors of caspase-3, p53, B-cell lymphoma 2 associated X protein (Bax) and anti-apoptosis factor of B-cell lymphoma 2 (Bcl-2) were detected by western blot. The viability of human bladder cancer with epirubicin or BCG treatment was decreased and the viability with epirubicin combined with BCG treatment was decreased more, which were determined by CCK-8 assay. Both epirubicin and BCG increased the apoptosis rate of human bladder cancer and arrested more cells into G0/G1 phase, which were tested by flow cytometry. The expression of caspase-3, p53 and Bax was increased and the expression of Bcl-2 was decreased with epirubicin treatment on human bladder cells, which were analyzed by western blot. The expression of caspase-3 and p53 was increased with BCG treatment, which was examined by western blot. Epirubicin induced apoptosis in human bladder cancer cells by up-regulating the expression of proapoptotic factors (caspase-3, p53 and Bax) and down-regulating the expression of anti-apoptotic factor (Bcl-2). BCG promoted apoptosis of human bladder cancer cells by up-regulating the expression of caspase-3 and p53. BCG plays a potential role at the time of the combination of epirubicin and BCG on bladder cancer cells in early stage. Both epirubicin and BCG affected cell cycle distribution via arresting more bladder cancer cells at G0/G1 phase, which ultimately led bladder cancer proliferation in vitro and promoted apoptosis.
