And the article was included in Journal of Surfactants and Detergents.Electric Literature of C25H46ClN The following contents are mentioned in the article:

The conductivity measurement has been used to determine the first and second CMC′s (CMC₁ and CMC₂) of alkyldimethylbenzylammonium chloride (C_nBCl; n = 12, 14 and 16) as well as gemini surfactant trimethylene-1,2-bis-(dodecyldimethylammonium bromide) (12-2-12) with sodium dodecylbenzenesulfonate (SDBS) in aqueous solutions using Rubing′s the regular theory approximation as well as the dissociated Margules Model. The use of Margules model allows us to calculate activity coefficients of the constituents and hence provides better values of micellar parameters for asym. mixed systems as compared to the regular solution theory. The CMC1 values for C_nBCl/SDBS mixtures were seen to be lower than those predicted from their ideal mixtures suggesting synergistic interactions although the synergism increases with chain length (n) of the cationic surfactant. Both CMC₁ and CMC₂ experience a decrease with rising values of n. The addition of salts including NaCl, KCl, NaBr, Na₃PO₄, and Na₂SO₄ in mixtures of C16BCl and SDBS suggests that salt counterions have a considerable impact on CMC1 when either surfactant is in excess. Zeta potential (ζ) measurements provide more evidence in favor of these observations. The thermodn. features of micellization have also been scrutinized using isothermal titration calorimetry (ITC). This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Electric Literature of C25H46ClN).

Photothermal therapy has always been a very attractive anti-cancer strategy, drawing a lot of attention thanks to its excellent performance as a non-invasive and pretty safe technique. Lately, nanostructures have become the main characters of the play of cancer therapy due to their ability to absorb near-IR radiation and efficient light-to-heat conversion. Here we present the synthesis of polyethylene glycol (PEG)-stabilized hybrid ultrasmall (<20 nm) gold-silver nanotriangles (AuAgNTrs) and their application in photothermal therapy. The obtained AuAgNTrs were deeply investigated using high-resolution transmission electron microscopy (HR-TEM). The cell viability assay was performed on U-87 glioblastoma multiforme cell model. Excellent photothermal performance of AuAgNTrs upon irradiation with NIR laser was demonstrated in suspension and in vitro, with >80% cell viability decrease already after 10 min laser irradiation with a laser power P = 3W/cm² that was proved to be harmless to the control cells. Moreover, a previous cell viability test had shown that the nanoparticles themselves were reasonably biocompatible: without irradiation cell viability remained high. Herein, we show that our hybrid AuAgNTrs exhibit very exciting potential as nanostructures for hyperthermia cancer therapy, mostly due to their easy synthesis protocol, excellent cell compatibility and promising photothermal features.

Aggregation and adsorption properties of benzyldimethylhexadecylammonium chloride (BDHAC) with three cationic alkanediyl-1,s-bis(tetradecyldimethyl-ammonium bromide) gemini surfactants, viz. butanediyl-1,4-bis(tetradecyldimethylammonium bromide), pentanediyl-1,5-bis(tetradecyldimethylammonium bromide) and hexanediyl-1,6-bis(tetradecyldimethylammonium bromide) resp. referred to as 14-4-14, 14-5-14 and 14-6-14 (in general 14-s-14, where s = 4, 5, 6) have been studied by tensiometric, conductometric, fluorimetric and dynamic light scattering exptl. methods at 298.15 K. The studies were conducted at various compositions of the mixed systems ranging between 0 and 1. The parameters determined include different physicochem. and interaction parameters. The neg. values of interaction parameters obtained for mixed micelle formation point out the attractive interaction among the components and lead to non-ideality which has been theor. treated by Clint′s and Rubingh′s models. The BDHAC + 14-s-14 mixtures in different mole fractions were used in the synthesis of very stable silver nanoparticles (Ag NPs) in aqueous media, which were characterized by UV-visible spectroscopy. Dynamic light scattering measurements revealed that the size of micelles as well as Ag NPs increases with the increase in mole fraction of BDHAC in the mixtures and the size of Ag NPs can be very much controlled by using mixtures of surfactants.

Influence of the addition of organo-montmorillonite nanofiller on cross-linking of polysiloxanes – FTIR studies was written by Wojcik-Bania, Monika. And the article was included in Spectrochimica Acta in 2021.Recommanded Product: 122-18-9 The following contents are mentioned in the article:

The main aim of the present work was to investigate the effect of organo-montmorillonite nanofiller on the crosslinking process of polysiloxane. Two series of model polysiloxane nanocomposites were prepared by incorporating organoclay at different amounts such as 0, 1, 2, 4, and 8 wt% in relation to the weight of the polymer matrix. Poly(methylhydrosiloxane) (PMHS) was cross-linked with two linear vinylsiloxanes of different chain lengths between functional end-groups through hydrosilylation. This reaction was carried out in the presence of Karstedt’s catalyst at equimolar ratios of reactive groups. Fourier-transform IR (FTIR) spectroscopic measurements obtained during the crosslinking processes as well as for the reaction products revealed that the rate of hydrosilylation and its efficiency are influenced by the type of the crosslinking agent used and the amount of organo-montmorillonite introduced into the polysiloxane network. Quant. anal. of the recorded FTIR spectra showed that as the amount of nanofiller in the polysiloxane matrix increased, the rate and efficiency of the crosslinking process decreased. Swelling measurements confirmed that the increase in the amount of unreacted Si-H groups in the system resulted in a lower cross-link d. of the studied materials. Furthermore, X-ray diffraction and transmission electron microscopy were performed to determine the nature of dispersion of organoclay within the studied systems. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Recommanded Product: 122-18-9).

Rapid analysis of benzalkonium chloride using paper spray mass spectrometry was written by Liu, Jingjing;Deng, Wenjie;Yu, Muqian;Wen, Ruizhi;Yao, Shouzhuo;Chen, Bo. And the article was included in Journal of Pharmaceutical and Biomedical Analysis in 2017.Electric Literature of C25H46ClN The following contents are mentioned in the article:

A paper spray mass spectrometry (PS-MS) method for rapid and reliable anal. of benzalkonium chloride (BAC) in compound eye drops and body surface disinfectant was developed. The sample was dropped onto triangular filter paper, and high voltage (3.5 kV) was applied to form an electrospray. This method can provide the composition of benzalkonium chloride in samples without pretreatment, solvent or chromatog. separation, and the anal. time is only 10 s. The primary homologs C₁₂-BAC, C₁₄-BAC and C₁₆-BAC of benzalkonium chloride were quant. analyzed using PS-MS. Samples were subjected to simple dilution and quantified using the internal standard method. Ion trap mass spectrometry was scanned using SIM mode. The linear ranges of C₁₂-BAC, C₁₄-BAC and C₁₆-BAC were 1-100 μg mL^-1; the linear regression coefficients were 0.998-0.999; the detection limits (LODs) were 0.1 μg mL^-1; the limit of quantifications (LOQs) was <1 μg mL^-1, and the method validation indicated that the method precision and accuracy were good. Compared with HPLC-UV methods, there was no significant difference in the quant. determination of the actual samples, but the anal. time for PS-MS is shorter (2 min). In addition, reagent consumption in PS-MS is small, and no chromatog. separation is needed, suggesting that PS-MS is especially suitable for high-throughput anal.

Ultrasound-assisted sample preparation for simultaneous extraction of anionic, cationic and non-ionic surfactants in sediment was written by Wiest, Laure;Giroud, Barbara;Fieu, Maeva;Assoumani, Azziz;Lestremau, Francois;Vulliet, Emmanuelle. And the article was included in Talanta in 2022.Recommanded Product: 122-18-9 The following contents are mentioned in the article:

Despite their very wide use in various fields, knowledge concerning surfactants in environmental solid matrixes is generally poor. One of the difficulties encountered in the anal. of surfactants is their very diverse physicochem. properties which require different extraction techniques. The objective of this work was therefore to develop an extraction method in sediments that allows the simultaneous anal. of anionic, cationic and non-ionic surfactants. Different extraction techniques (salting-out, ultrasound), solvents and additives were compared. The optimized method, followed by anal. by coupling liquid chromatog. with tandem mass spectrometry, was then validated and applied to real samples in which the analytes were quantified by matrix matched calibration. Optimization of the extraction parameters showed different trends depending on the surfactant family. However, ultrasound assisted extraction with a 90/10 acetonitrile/water mixture at 1% acetic acid and 0.1 M EDTA showed the best results overall. The quantification limits obtained, between 6.4μg/kg for linear alkylbenzene sulfonate (LAS) C10 and 158μg/kg for 1-laureth sulfate, allow the anal. of traces in sediments. Eighteen of the 27 targeted surfactants were thus detected. The highest concentrations were found for LAS and quaternary ammoniums. Strong correlations between concentrations of different homologues of the same families of surfactants were observed This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Recommanded Product: 122-18-9).

How the type of interface can alter the behavior of an aprotic ionic liquid-water mixture entrapped in different reverse micelles: An exploratory study using an enzymatic reaction as a sensor was written by Blach, Diana;Girardi, Valeria R.;Silber, Juana J.;Correa, N. Mariano;Falcone, R. Dario. And the article was included in Colloids and Surfaces, A: Physicochemical and Engineering Aspects in 2022.Electric Literature of C25H46ClN The following contents are mentioned in the article:

In this work, we decipher how an aprotic Ionic Liquid (IL)-water mixture structure can be altered upon confinement in different reverse micelles (RMs) media. Thus, the effect of the polar pseudophase composition in RMs formulated by anionic or cationic surfactants was monitored using the well-known enzymic hydrolysis reaction of 1-naphthyl phosphate (1-NP) with alk. phosphatase (AP). Water and an aqueous mixture formed by the IL 1-butyl-3-methylimidazolium trifluoromethanesulfonate ([C4C1i.m., TfO]) as the polar pseudophase were used. As surfactants, the anionic sodium diethylhexyl sulfosuccinate (AOT) and the cationic benzyl-n-hexadecyldimethylammonium chloride (BHDC) were employed. The effect of the nanoconfinement, as well as the impact of the polar solvent content and the type of interface, were analyzed by determining the Michaelis-Menten parameters. In homogeneous media, the catalytic efficiency of the hydrolysis reaction is strongly dependent on the amount of water in the mixtures evaluated. In RMs the catalytic efficiency is dependent on both, the polar content and the type of surfactant used. Thus, by using a model reaction with an enzyme entrapped inside different RMs it was possible to learn that an aprotic IL:water mixture can be strongly disturbed when it is confined in a cationic or anionic RMs. This particular behavior can produce a deep impact on the technol. applications of these organized systems.

Degradation of cationic surfactants using immobilized bacteria: Its effect on adsorption to activated sludge was written by Bergero, Maria F.;Lucchesi, Gloria I.. And the article was included in Journal of Biotechnology in 2018.COA of Formula: C25H46ClN The following contents are mentioned in the article:

Adsorption of cationic surfactants (QACs) Br-tetradecyltrimethylammonium (TTAB), Cl-tetradecylbenzyldimethylammonium (C₁₄BDMA) and Cl-hexadecylbenzyldimethylammonium (C₁₆BDMA) to activated sludge from a wastewater treatment plant was tested. Adsorption equilibrium was reached after 2h, and for initial 200mgL^-1 81%, 90% and 98% of TTAB, C₁₄BDMA and C₁₆BDMA were resp. adsorbed. After six successive desorption cycles, 21% of TTAB and 12.7% of C₁₄BDMA were desorbed from the sludge. In agreement with the percentage of QACs pre-adsorbed, the more hydrophobic the compound, the lesser the extent of desorption. Wastewater samples with activated sludge were supplemented with TTAB 200mgL^-1 and Ca-alginate beads containing the QACs-degrading microorganisms Pseudomonas putida A (ATCC 12633) and Aeromonas hydrophila MFB03. After 24h, 10mgL^-1 of TTAB were detected in the liquid phase and 6-8mgL^-1 adsorbed to the sludge. Since without Ca-alginate beads or with empty beads total TTAB amount (phase solid and liquid) did not change, the 90% reduction of the initial 200mgL^-1 after treatment with immobilized cells was attributed to the bacterial consortium’s capacity to biodegrade QACs. The results show the advantages of using immobilized bacteria to achieve complete QACs elimination from wastewater systems, thus preventing them from reaching the environment.

A number of techniques, including conductivity, surface tension, dynamic light scattering, transmission electron microscopy, and ¹H NMR (¹H NMR), Fourier transform IR (FT-IR), and ¹H-¹H 2D nuclear Overhauser effect spectroscopy (¹H-¹H 2D NOESY), have been used to investigate the effect of amide bonds on the interfacial and assembly properties of a cationic surfactant, N-anilinoformylmethyl-N-cetyl-N,N-dimethyl ammonium chloride (AMC-C₁₆), in aqueous solutions The adsorption of AMC-C₁₆ has been found to be much better than that of the conventional cationic surfactant, benzyl cetyldimethylammonium chloride (BAC-16) at the air/water interface and in solution The surface tension measurements show the presence of two critical aggregation concentrations (CAC₁ and CAC₂) for AMC-C₁₆. The presence of a strong intermol. hydrogen bond of AMC-C₁₆ was confirmed by ¹H NMR and FT-TR. The mol. interactions of AMC-C₁₆ were detected by ¹H-¹H 2D NOESY.

Gold nanoparticles optical properties induced by water and an ionic liquid (bmimBF₄) inside cationic reverse micelles was written by Blach, Diana;Martinez O., Fernando. And the article was included in New Journal of Chemistry in 2017.Electric Literature of C25H46ClN The following contents are mentioned in the article:

The authors report the effect of a polar solvent entrapped in benzyl-n-hexadecyldimethylammonium chloride (BHDC) reverse micelles (RMs) as nanoreactors for the synthesis of gold nanoparticles (AuNPs). We evaluate how the room temperature ionic liquid (RTIL) 1-butyl-3-methylimidazolium tetrafluoroborate (bmimBF₄) and water inside the RMs could control the interactions at the interface as a key factor that affects the final properties of the synthesized nanoparticles. The results show that the bmimBF₄ supramol. network under confinement plays an important role in the nucleation and growth mechanism of AuNPs. In addition, the results show how the polar solvent could induce a specific interaction at the interface, including ionic segregation, which affects the BHDC chloride (Cl^–) counterion availability at the interface, droplet size, interface flexibility and thus the material exchange rate between droplets. These factors strongly influence the AuNPs size, polydispersity, morphol. and crystallinity. The RTIL bmimBF₄ in BHDC RMs induces a decrease in ionic segregation of the Cl^– ions available at the interface which favors sphericity and monocrystallinity in the AuNPs formed. Moreover, water does not affect the availability of Cl^– ions at the interface, and the insertion of these ions in the previous crystalline layer is a key factor in the anisotropy and polycrystallinity of the AuNPs obtained. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Electric Literature of C25H46ClN).
