Thermodynamic and spectroscopic studies on cationic surfactant tetradecyltrimethylammonium bromide in aqueous solution of trisubstituted ionic liquid 1, 2-dimethyl-3-octylimidazolium chloride at different temperatures

In this work, the effects on micellar behavior of long chain cationic surfactant tetradecyltrimethylammonium bromide (TTAB) upon the addition of trisubstituted ionic liquid (IL), 1, 2-dimethyl-3-octylimidazolium chloride [odmim][Cl] at temperatures, 298.15?318.15 K has been studied. Different techniques such as conductance, surface tension, fluorescence and H-1 NMR have been employed to understand the interactional mechanisms. The values of critical micelle concentration (cmc) and various thermodynamic parameters have been calculated from conductivity measurements. The surface parameters like effectiveness of decrease in surface tension (?(cmc)), minimum surface area occupied per surfactant monomer (A(min)), maximum surface excess concentration (?(max)), and adsorption efficiency (pC(20)) have been evaluated by surface tension measurements. Micellar aggregation number (N-agg) has been determined by quenching of pyrene. Further to understand interactions in post micellar region, H-1 NMR measurements have been performed. It has been observed that the lipophilicity of interacting ion modified the thermodynamic and aggregation properties of TTAB.

Effects of microbubble pre-ozonation time and pH on trihalomethanes and haloacetic acids formation in pilot-scale tropical peat water treatments for drinking water purposes

The high concentrations of dissolved organicmatter (DOM), chloride, and bromide in tropical peat water have a significant impact on the formation of carcinogenic disinfection by-products (DBPs) such as trihalomethanes (THMs) and haloacetic acids (HAAs), especially during the chlorination process. Therefore, other pretreatment methods to effectively remove these harmful substances in the water during treatment are needed. The aim of this study was to determine the effects of microbubble pre-ozonation pH on the reduction of THM4 and HAA5 formed during the peat water treatment process and to determine the best conditions for microbubble pre-ozonation to reduce the formation of these two classes of DBPs. The microbubble pre-ozonation was conducted at a pH of 5.5, 7, and 8.5. Furthermore, the primary treatments applied after this pretreatment were coagulation and activated carbon adsorption before post-chlorine disinfection. The coagulation process using aluminum sulfate and activated carbon adsorption succeeded in reducing the formation of THM4 after chlorination, to a level below USEPA standards, but the concentration of HAA5 was still high. However, the use of microbubble preozonation significantly reduced the formation of both classes of compounds during the chlorination process of the peatwater. Also, the concentration of THM4 increased during the pre-ozonation process in all pH conditions, but HAA5 decreased except in alkaline state. Furthermore, the ideal conditions for microbubble pre-ozonation on peat water were at pH 7 (neutral) after 30 min, with the total THM4 concentration at 33.73 +/- 0.40 mu g/L, and that of HAA5 at 49.89 +/- 0.09 mu g/L, falling below the USEPA standard.

Phosphorus-halogen bond elongation and autoionization in a Cl,Br,I-series of N-heterocyclic phosphane halides with saturated backbone: diazaphosphorinane vs. diazaphosphorinenium salt

Halide exchange reactions of PX3 (X = Br, I) and the known 1,3-di-tert-butyl-2-chloro-1,3,2-diazaphosphorinane (1) gave the bromide (2) and the iodide (3). The new compounds have been characterized by elemental analysis, IR and NMR spectroscopy. H-1, C-13 and P-31 NMR spectroscopic data give strong evidence for a non-ionic behaviour of 1, 2 and 3 in solution. Single crystal X-ray structure determinations of 2 and 3 for the first time allowed for a detailed comparative study of the solid state structures of a Cl,Br,Iseries of NHPXs with aliphatic backbone. Like in 1 in 2 a partially flattened cyclohexane-like chair conformation with the nitrogen atom substituents in a diequatorial orientation and a substantially elongated covalent bond between the phosphorus atom and the axial oriented halogen atom is found. Neither a covalent P-I bond nor a preferred chair conformation is present in the solid autoionization product 3 that should be labelled phosphorinenium iodide instead of P-iodophosphorinane. Its solid state structural parameters are in line with the expectations for a [-N(tBu)](2)>P+-fragment with high diazaphosphaallyl cationic character. (C) 2020 Elsevier Ltd. All rights reserved.

Design, synthesis and evaluation of halogenated furanone derivatives as quorum sensing inhibitors in Pseudomonas aeruginosa

The biofilm formation of Pseudomonas aeruginosa (P. aeruginosa) is regulated by a phenomenon of quorum sensing (QS). With 5-hydroxyl-3,4-halogenated-5H-furan-2-ones as beginning, analogs bearing alkyl chains, vinyl bromide, or aromatic rings were designed and synthesized. The minimum inhibitory concentration (MIC) of the compounds against P. aeruginosa was assayed and the biofilm inhibition ratio was determined at different concentrations lower than the MIC. C-5 aromatic substituted furanones showed remarkable biofilm formation as well as inhibition of virulence factor production in P. aeruginosa. Fluorescence report analysis identified the QS regulatory mechanism of the most active compound 29. This study provides us a novel candidate for combating drug resistant bacteria strains by merely inhibiting biofilm formation. Without suppressing the regular life cycle of the bacteria, bacterial resistance mechanisms may not be activated.

An overview of bromate formation in chemical oxidation processes: Occurrence, mechanism, influencing factors, risk assessment, and control strategies

Chemical oxidation processes have been extensively utilized in disinfection and removal of emerging organic contaminants in recent decades. Some undesired byproducts, however, are produced in these processes. Of them, bromate has attracted the most intensive attention. It was previously regarded as a byproduct that typically occurred in ozone-based oxidation processes. However, for the past decade, bromate formation has been detected in other oxidation processes such as CuO-catalyzed chlorination, SO4 center dot–based oxidation, and ferrate oxidation processes. This review summarizes the occurrences, mechanisms, influencing factors, risk assessment, and control strategies of bromate formation in the four oxidation processes, i.e., ozone-based oxidation, chlorine-based oxidation, SO4 center dot–based oxidation, and ferrate oxidation. Besides, some unresolved issues for future studies are provided: (1) Clarification of the relative contributions of SO4 center dot- and Br center dot to the oxidation of bromine for bromate formation in SO4 center dot–based oxidation processes; (2) evaluation of the role of different reactive species in the bromate formation in the process of UV/HOCl; (3) quantification of the dual role of alkalinity in bromate formation during ozonation; (4) assessment of the risks of bromate formation in SO4 center dot–based oxidation processes for practical applications; and (5) exploration of strategies for inhibiting bromate formation in SO4 center dot–based oxidation, UV/chlorine, and metal oxide-catalyzed chlorination processes.

DNA and RNA binding studies on a novel bromo-bridged dimeric copper(II) complex stabilized from a Schiff base ligand

A novel red copper(II) compound, bis(mu-bromo)bis(2-(benzothiazol-2-yl-hydrazono)-1,2-diphenyl-ethanone)-dicopper(II) (1), has been fostered by equimolar reaction of a Schiff-base ligand, 2-(benzothiazol-2-yl-hydrazono)-1,2-diphenyl-ethanone (LH), with copper(II) bromide in satisfactory yield. 1 has thoroughly been characterized by C, H and N elemental analyses, FT-IR and UV-vis (both in solid state and in solution) spectroscopies, and room-temperature magnetic susceptibility and conductivity measurements. Dimeric 1 bears symmetric rare bromo-bridges in its crystal structure. 1 retains its solid-state identity even in a protic solvent like methanol. 1 in methanol displays two-step one-electron redox response. Theoretical calculations based on DFT were executed to probe the electronic structure of 1 and to augment its color. DNA- and RNA-binding aspects of both LH and 1 have been explored. Thermodynamic binding parameters have been determined. LH is a major-groove binder to DNA, while 1 manifests itself as a minor-groove binder. This binding has been corroborated through molecular docking. Nucleic acid binding aspect of such type of rare bromo-bridged red copper(II) dimer is unprecedented.

Biocompatible supramolecular systems based on novel cationic imidazolium- and urethane-containing amphiphiles: Self-assembly and antimicrobial properties

In the framework of this investigation novel cationic amphiphiles of N-(2-butylaminocarbonyloxyethyl)-N-alkylimidazolium bromides series have been synthesized and characterized in terms of their aggregation capacity in aqueous solutions, antimicrobial properties and solubilization action toward hydrophobic dye. Using tensiometry, conductometry and fluorescence spectroscopy techniques it has been demonstrated, that the presence of urethane fragment with butyl moiety is responsible for the one order of magnitude decrease of critical micelle concentration of amphiphiles in comparison with unsubstituted analogs. Fabrication of aggregates with hydrodynamic diameter in the range of 4-10 nm has been exhibited for all amphiphiles. Transmission electron microscopy technique allows to establish the spherical shape of aggregates formed. These amphiphiles were shown as effective solubilizers of hydrophobic azodye, which efficacy could be 2.5-fold increased by elongation of the length of hydrophobic tail by four methylene units. Estimation of interaction of amphiphiles with biological objects has revealed, that all compounds exhibit high bacteriostatic and bactericide properties preferably toward gram-positive strains, as well as they have low hemolytic activity at active concentrations. Antibacterial properties of tetradecyl amphiphilic derivative have surpassed norfloxacin by S and 85 times in relation to Staphylococcus aureus and Bacillus cereus, respectively.

Study on Hydrolysis of Magnesium Hydride by Interface Control

Magnesium hydride (MgH2) is one of the competitive hydrogen storage materials on account of abundant reserves and high hydrogen content. The hydrolysis of MgH2 is an ideal and controllable chemical hydrogen generation process. However, the hydrolyzed product of MgH2 is a passivation layer on the surface of the magnesium hydride, which will make the reaction continuity worse and reduce the rate of hydrogen release. In this work, hydrogen generation is controllably achieved by regulating the change of the surface tension value in the hydrolysis, a variety of surfactants were systematically investigated for the effect of the hydrolysis of MgH2 In the meantime, the passivation layer of MgH2 was observed by scanning electron microscope (SEM), and the surface tension value of the solution with different surfactants were monitored, investing the mechanism of hydrolysis adding different surfactants. Results show that different surfactants have different effects on hydrogen generation. The hydrogen generation capacity from high to low is as follows: tetrapropylammonium bromide (TPABr), sodium dodecyl benzene sulfonate (SDBS), Ecosol 507, octadecyl trimethyl ammonium chloride (OTAC), sodium alcohol ether sulfate (AES), and fatty methyl ester sulfonate (FMES-70). When the ratio of MgH2 to TPABr was 5 : 1, the hydrogen generation was increased by 52% and 28.3%, respectively, at the time of 100 s and 300 s. When hydrolysis time exceeds 80 s, the hydrogen generation with AES and FMES-70 began to decrease; it was reduced by more than 20% at the time of 300 s. SEM reveals that surfactants can affect the crystalline arrangement of Mg(OH)(2) and make the passivation layer three-dimensionally layered providing channels for H2O molecules to react with MgH2.

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 4286-55-9, in my other articles.

Photobrightening in Lead Halide Perovskites: Observations, Mechanisms, and Future Potential

There has been a meteoric rise in the commercial potential of lead halide perovskite optoelectronic devices since photovoltaic cells and light-emitting diodes based on these materials were first demonstrated. One key challenge common to each of these optoelectronic devices is the need to suppress nonradiative recombination, a process that limits the maximum achievable efficiency in photovoltaic cells and light-emitting diodes. In this Progress Report, recent studies that seek to minimize this loss pathway in perovskites through a photobrightening treatment, whereby the luminescence efficiency is enhanced through a light illumination passivation process are examined. The sensitivity of this effect to various experimental considerations is examined, including atmosphere, photon energy, photon dose, and also the role of perovskite composition and morphology; under certain conditions there can even be photodarkening effects. Consideration of these factors is critical to resolve seemingly conflicting literature reports. Proposed mechanisms are scrutinized, revealing that there is now some consensus but further work is needed to identify the specific defects being passivated and elucidate universal mechanisms. Finally, the prospects for these treatments to minimize halide migration and push the properties of polycrystalline films towards those of their single-crystal counterparts are discussed.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 4286-55-9. Name: 6-Bromohexan-1-ol.
