A facile and highly porous heterogeneous matrix was designed as a support for zero-valent Cu nanoparticles. This heterogeneous support is composed of filter paper, chitosan, and titanium dioxide, and on this support matrix, a metallic Cu2+ nanoparticle was loaded. The metallic Cu2+ nanoparticle was then reduced to Cu0 in NaBH4 solution The prepared catalyst (Cu/CHTiO2/FP) was characterized by X-ray diffraction (XRD), Fourier transforms IR spectroscopy (FTIR), scanning electronic microscopy (SEM), energy-dispersive X-ray spectrometry (EDS), and energy-dispersive X-ray spectroscopy (XPS) and the results indicated that the synthesis of zero-valent Cu nanoparticles on the heterogeneous support by this method was successful. The prepared Cu/CHTiO2/FP catalytic activity was investigated to remove four different textile dyes: Rhodamine B, Bromocresol Green, Methyl orange, and Eriochrome Black T in the presence of NaBH4. The results show that the catalyst is efficient and can be adapted to remove the different classes of dyes studied. Aside from the catalyst’s efficiency, it could be quickly recovered by simply pulling out from the reaction medium, washed, and reused. The reusability of the catalyst recorded over 90% removal after five cycles.

In organic chemistry, atoms other than carbon and hydrogen are generally referred to as heteroatoms. The most common heteroatoms are nitrogen, oxygen and sulfur. Now I present to you an article called Silver nanoparticles incorporated in dicarboxylic/TEPA modified halloysite nanotubes for the degradation of organic contaminants, published in 2020-11-30, which mentions a compound: 76-60-8, mainly applied to silver nanoparticle dicarboxylic acid TEPA halloysite nanotube organic contaminant, Product Details of 76-60-8.

Silver supported on organo-modified halloysite nanotubes (Ag-HNTX/T) were fabricated through three steps of modifications; (i) functionalization of pristine halloysite nanotubes (HNT) with dicarboxylic acids, namely succinic acid (SA), oxalic acid (OX), or sebacic acid (SB), (ii) addition of tetraethylenepentamine (TEPA), and finally (iii) incorporation of silver particles (Ag). The modification with dicarboxylic acid and TEPA on HNT was proven by the presence of -COOH and -NH functional groups in the FTIR spectra. Upon introduction of Ag particles on the organo-modified HNT, the Ag-HNTSA/T sample exhibits UV-DRS absorption at 460 nm, corresponding to the presence of Ag particles with the average size of 12.1 ± 6.5 nm. The HRTEM result reveals that Ag particles are deposited on the surface and inside the lumen of HNT, which is in-line with slight decrease in SBET attributed to some pore blocking in Ag-HNTSA/T. The catalytic activity of the fabricated Ag-HNTX/T (X = SA, OX or SB) was evaluated through the borohydride-assisted degradation of organic contaminants, i.e. methyl orange (MO), methylene blue (MB), p-nitrophenol (p-NP), and bromocresol green (BG). The Ag-HNTX/T catalyst exhibited excellent catalytic activity and the process follows the pseudo-first order kinetics. The Ag-HNTX/T possesses sustainable catalytic performance up to 15 recycled applications.

The chemical properties of alicyclic heterocycles are similar to those of the corresponding chain compounds. 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 Removal of Bromocresol Green from aqueous solution by electro-Fenton and electro-Fenton-like processes with different catalysts: laboratory and kinetic model investigation, the main research direction is bromocresol green aqueous solution kinetic model.Synthetic Route of C21H14Br4O5S.

This study presents the removal of triarylmethane dye Bromocresol Green from aqueous solution by the electro-Fenton process. As catalysts five different cations were used: Fe2+, Ce3+, Ni2+, Mn2+, and Co2+. They play crucial roles in the whole process because they react with H2O2 producing hydroxyl radicals that are capable of breaking down dye mols. Based on this, a comparison of catalytic activity of these cations in the electro-Fenton process is made for Bromocresol Green degradation A simple and universal kinetic model is also applied to study the catalytic activity of investigated catalysts. Due to its multidimensionality it is fitted to exptl. data using a genetic algorithm. The procedure of fitting using a genetic algorithm is thoroughly described and demonstrated. The activity of utilized catalysts is compared based on both exptl. and model data revealing that for Bromocresol Green removal all alternative catalysts (Ni2+, Co2+, Ce3+, Mn2+) are better than the typical one (Fe2+, 51.83% degradation). The best catalyst is Co2+ with 78.35% degradation efficiency. Moreover, the adopted kinetic model proved its universality and outlined different interactions between catalysts and dye mols.

Epoxy compounds usually have stronger nucleophilic ability, because the alkyl group on the oxygen atom makes the bond angle smaller, which makes the lone pair of electrons react more dissimilarly with the electron-deficient system. 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 Ligand binding to natural and modified human serum albumin.Application In Synthesis of 3,3-Bis(3,5-dibromo-4-hydroxy-2-methylphenyl)-3H-benzo[c][1,2]oxathiole 1,1-dioxide.

This paper reports evaluation of ligand binding constants for unmodified or biotinylated HSA (HSAB) for two well-known HSA binding ligands, naproxen and bromocresol green. Results demonstrate differential scanning calorimetry (DSC) is a reliable quant. method for straight-forward and rapid evaluation of ligand binding constants for HSA and modified derivatives DSC measured the thermodn. stability of free and ligand-bound HSA and HSAB at pH = 6.0, 7.4 and 8.0. DSC anal. provided a quant. gauge of responses of HSA and HSAB thermodn. stability to ligand binding. The influence of different levels of biotinylation of HSAB on ligand binding, and how ligand binding varied as a function of pH for these mols. was also examined In the three pH environments, biotinylation increased stability of HSAB alone compared to free HSA at pH 7.4. Stabilities of free protein and ligand-bound complexes varied with pH in the order, pH = 6.0>7.4>8.0. Our anal. approach provided very accurate estimates for known binding constants of these ligands for HSA. Results revealed, for both ligands, extent of biotinylation of HSAB affected binding, reducing binding constants from three to 100-fold. DSC anal. was able to delineate inter-relationships between mol. structure and thermodn. stability of HSA and HSAB bound by ligands; and their variations with pH.

In a document, author is Yaikhan, Thanachaporn.

Intercellular communication is a crucial process for the multicellular community in both prokaryotes and eukaryotes. Indole has been recognized as a new member of the signal molecules which enables the regulated control of various bacterial phenotypes. To elucidate the inter-species relationship among enteric microorganisms via indole signaling, Klebsiella pneumoniae (KP) culture was treated with indole solution and examined for the pathogenicity by using various phenotypic tests. Both synthetic and naturally-produced indole preparations had no deteriorating effect on growth and autoaggregative capacity of KP. The results showed that biofilm formation of carbapenem-susceptible K. pneumoniae (KP-S) was clearly induced by indole exposure (approximate to 2-10 folds), whereas no significant difference was observed in the resistant counterpart. In addition, the tolerance to beta-lactam antibiotics of KP was altered upon exposure to indole and/or derivatives assessed by Kirby-Bauer disk diffusion test. Taken together, our finding indicates the functional role of indole in changing or modulating pathogenic behaviors of other bacteria.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 520-27-4, in my other articles.

Thirty unreported indole derivatives containing dithioacetal moiety were synthesized and evaluated for antiplant viral activity. Bioassay results displayed that some of the target compounds showed better activities against tobacco mosaic virus (TMV) than the commercial Ribavirin in vivo. In particular, anti-TMV curative, protective and inactivating activity of 4p were 55.1, 57.2, and 80.3%, respectively, and EC50 value for inactivating activity was 88.5 mu g/mL. The observation of transmission electron microscope showed that 4p may have a certain destructive effect on TMV particles. To further study, microscale thermophoresis analysis result also demonstrated that 4p powerfully interacted with TMV coat protein in vitro. Hence, this study provides a strong evidence suporting that indole derivatives might be applied as new antiviral agents.

Indole-3-carbinol (I3C), a hydrolysis product of indole-3-methylglucosinolate, is toxic to herbivorous insects and pathogens. In mammals, I3C is extensively studied for its properties in cancer prevention and treatment. Produced in Brassicaceae, I3C reversibly inhibits root elongation in a concentration-dependent manner. This inhibition is partially explained by the antagonistic action of I3C on auxin signaling through TIR1. To further elucidate the mode of action of I3C in plants, we have identified and characterized a novel Arabidopsis mutant tolerant to I3C, ICT1. This mutant was identified following screening of the Full-length cDNA Over-eXpression library (FOX) seed collection for root growth in the presence of exogenous I3C. ICT1 carries the AT2G19750 gene, which encodes an S30 ribosomal protein. Overexpression, but not knockout, of the S30 gene causes tolerance to I3C. The tolerance is specific to I3C, since ICT1 did not exhibit pronounced tolerance to other indole or benzoxazinoid molecules tested. ICT1 maintains I3C-induced antagonism of auxin signaling, indicating that the tolerance is due to an auxin-independent mechanism. Transcript profiling experiments revealed that ICT1 is transcriptionally primed to respond to I3C treatment.
