And the article was included in Chemical Papers in 2022.Application In Synthesis of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

Surface behavior and interfacial mixing properties of the cationic surfactant hexadecyl benzylammonium chloride (HDBAC) and anionic one sodium di-2-ethylhexylsulfosuccinate (AOT) were studied at four temperatures (288-318 K) in an aqueous solution using tensiometry method. The critical micelle concentration (CMC) for individual and binary mixture was evaluated to gain the interfacial parameters such as surface excess concentration, min. area per mols. of single and mixture system, and interfacial free energy. The results show expansion of min. area per mols. of binary mixture (about 1000-2500 Ų) compared with that of single surfactants (about 100-250 Ų). Based on Rosen′s model, the synergism parameters were calculated and the data obtained show that neg. values of mol. interaction parameter (β^σ ) indicate an attractive interaction between the surfactants, where the more neg. value was – 7.63146 for the mixture of 90% AOT and 10% HDBAC. Also, the values of activity coefficients less than unity indicate a strong synergistic interaction between the two surfactants. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Application In Synthesis of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride).

The effects of polymeric molar mass, concentration, and adding of different surfactants on the electrospun poly(vinyl alcohol) nanofibers was written by Eren Boncu, Tugba;Ozdemir, Nurten. And the article was included in Latin American Journal of Pharmacy in 2019.SDS of cas: 122-18-9 The following contents are mentioned in the article:

The aim of the study is to produce nanofibers using electrospinning with aqueous poly(vinyl alc.)(PVA) solutions Effect of PVA molar mass and concentration and effect of surfactants on the properties of PVA solutions and on the diameter size of electrospun PVA nanofibers were examined It was shown that the viscosity of the polymer solution was increased by increasing PVA molar mass and concentration To obtain the nanofiber structure, optimum PVA_18.000 (molar mass = 18,000 g/mol) and PVA_50.000 (molar mass = 50,000 g/mol) concentrations were found to be 30% weight/weight and 20% weight/weight, resp. With the addition of anionic and cationic surfactants, the viscosity and the elec. conductivity of the polymer solutions were increased while the surface tension and fiber diameters of the nanofibers were decreased (p < 0.05). However, nonionic surfactants have shown no statistically significant effect (p > 0.05). As a result, electrospun nanofibers were produced using PVA and water and the diameters and properties of nanofibers can be modified by controlling the parameters examined in the study. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9SDS of cas: 122-18-9).

Atomic vibrations and phonons are an excellent source of information on nanomaterials that the authors can access through a variety of methods including Raman scattering, IR spectroscopy, and EELS. In the presence of a plasmon local field, vibrations are strongly modified and, in particular, their dipolar strengths are highly enhanced, thus rendering Raman scattering and IR spectroscopy extremely sensitive techniques. Exptl. the interaction between a relativistic electron and vibrational modes in nanostructures is fundamentally modified in the presence of plasmons. The authors finely tune the energy of surface plasmons in metallic nanowires in the vicinity of hexagonal BN, making it possible to monitor and disentangle both strong phonon-plasmon coupling and plasmon-driven phonon enhancement at the nanometer scale. Because of the near-field character of the electron beam-phonon interaction, optically inactive phonon modes are also observed Besides increasing the understanding of phonon physics, the results hold great potential for studying sensing mechanisms and chem. in complex nanomaterials down to the mol. level.

Gold Nanoearbuds: Seed-Mediated Synthesis and the Emergence of Three Plasmonic Peaks was written by Roy, Debashree;Xu, Yi;Rajendra, Ranguwar;Wu, Lin;Bai, Ping;Ballav, Nirmalya. And the article was included in Journal of Physical Chemistry Letters in 2020.Electric Literature of C25H46ClN The following contents are mentioned in the article:

We demonstrate the first successful synthesis of reasonably monodisperse and single-crystalline gold nanoearbuds (Au NEBs) using a binary surfactant mixture of cetyltrimethylammonium chloride (CTAC) and benzyldimethylhexadecylammonium chloride (BDAC) in seed-mediated growth method. We have focused on the key chem. parameters behind the formation and growth of Au NEBs to result in tunable dimensions (length, 37-77 nm; width, 4-6 nm; aspect ratio, 7-19), as a consequence of which the longitudinal surface plasmon resonance (LSPR) peak could be tuned beyond 1200 nm. The achievement of LSPR beyond 1200 nm while maintaining the dimension well below 100 nm is a challenging accomplishment in the realm of one-dimensional (1D) Au nanostructures. This earbud-like morphol. addnl. exhibits three plasmonic peaks, rather uncommon for 1D nanostructures, which were analyzed theor. based on the finite element method. The new resonance peak of the Au NEB was assigned as an addnl. longitudinal mode intensified by the bulbous ends as well as the high aspect ratio, thereby providing conclusive evidence that it is indeed a new morphol.

Non-aqueous reverse micelles created with a cationic surfactant: Encapsulating ethylene glycol in BHDC/non-polar solvent blends was written by Agazzi, Federico M.;Falcone, R. Dario;Silber, Juana J.;Correa, N. Mariano. And the article was included in Colloids and Surfaces, A: Physicochemical and Engineering Aspects in 2016.Electric Literature of C25H46ClN The following contents are mentioned in the article:

We present results on a new system that forms non-aqueous reverse micelles (RMs) created with a cationic surfactant, benzyl-n-hexadecyldimethylammonium chloride (BHDC), encapsulating ethylene glycol (EG), in different nonpolar solvents blends of n-heptane:benzene. It is shown that a cationic surfactant forms RMs using EG as polar solvent without the addition of a co-surfactant. In particular, we analyzed the EG solubilization capacity, the droplet size values and the interface composition of EG/BHDC/n-heptane:benzene RMs, using dynamic light scattering (DLS) and the solvatochromic behavior of 1-methyl-8-oxyquinolinium betaine (QB) as mol. dye. The EG solubilization capacity depends on the external phase composition decreasing when the n-heptane content increases. Using DLS technique, we demonstrate the formation of RMs, and observe that for the same [EG]/[BHDC] ratio, the micellar size increases when n-heptane content increases. Using QB it was found that EG penetrates into the micellar interface changing dramatically the composition and the droplet-droplet interaction, in comparison when water is encapsulated.

The importance of studying mixed micellar and surface-active features of ionic liquid-surfactant systems in surfactant chem. research is enormous due to the wide range of potential uses of such systems. The mixed micellar behavior gets influenced by the presence of additives like gelatin in the solution Using conductivity and refractive index measurement techniques, the mixed micellar properties of surface-active ionic liquid (SAIL) 1-dodecyl-3-methylimidazolium chloride [C₁₂mim][Cl] and cationic surfactant benzyldimethyl-n-hexadecylammonium chloride (16-BAC) were investigated in aqueous media and gelatin protein solution at (293.15, 298.15, 303.15, and 308.15) K. Surface tension measurement technique was used to confirm the critical micelle concentration (cmc) values and calculate different surface-active parameters for [C₁₂mim][Cl]/[16-BAC] mixed system at 298.15 K.

QuEChERS-based purification coupled with UPLC-MS/MS method, was developed for six quaternary ammonium compounds (QACs) determination in dairy products. Powder samples were firstly dispersed by water. Protein in liquid milk was precipitated and sample solution was extracted by acetonitrile. QuEChERS-based purification was used to purify the solution QACs were finally separated by HILIC column and detected in MRM mode of MS/MS under ESI⁺. The stable isotope benzyl-2,3,4,5,6-d₅-dimethyltetradecylammonium bromide (C₁₄-BAC-d₅) was used as an internal standard This method was validated in terms of linearity, sensitivity, precision, accuracy. Linear relations were favorable for QACs over the selected concentration ranges of 0.2-50 μg/L, with correlation coefficients greater than 0.999. The limits of detection (LODs) were in the range of 0.4-14.5 μg/kg. Recoveries were between 91.2% and 115% with RSDs of 2.8-7.5% for intra-day precision and 3.7-6.7% for inter-day precision.

QuEChERS: a simple extraction for monitoring quaternary ammonium biocide pollution in soils and antimicrobial resistance was written by Godfrey, A. Ruth;Townsend, Rachel;Desbrow, Claire;Felion, Celeste. And the article was included in Analytical Methods in 2020.COA of Formula: C25H46ClN The following contents are mentioned in the article:

Quaternary ammonium compounds (QACs) are broad-spectrum disinfectants used in a range of everyday materials. Their high usage rates, limited regulation and reporting has meant their environmental release is largely uncontrolled and impact unknown. With links to antimicrobial resistance (AMR) and adsorption to wastewater solids (that are recycled), there is a need for more controlled disposal measures and monitoring. These environmental matrixes are highly complex requiring methods that are often laborious and costly to undertake. Using a robust quant. reversed-phase LC-MS/MS method, we have shown that an ‘off the shelf’ QuEChERS product can reliably extract (<10% RSD) aromatic and aliphatic QACs anticipated within municipal, industrial and agricultural waste from water and soil, with reduced matrix effects of 95.7-104.4% for recoveries of up to 53% from soil when combined with extract dilution Therefore, unlike current literature, this work has shown that, with minimal development, the QuEChERS product can provide a rapid, effective and low cost preparation for quantifying QAC pollution and monitoring AMR. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9COA of Formula: C25H46ClN).

Influence of serum concentration and surface functionalization on the protein adsorption to mesoporous silica nanoparticles was written by Lin, Chih-Yu;Yang, Chia-Min;Linden, Mika. And the article was included in RSC Advances in 2019.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

A study of a protein corona on mesoporous silica nanoparticles (MSNs) at in vitro and in vivo relevant serum concentrations is presented. Three MSNs different in terms of mesoscopic pore arrangement, surface chem. and surface roughness were studied. After incubation in either 10% or 100% serum, the hard protein corona-particle complexes were collected and analyzed by DLS, zeta-potential, and TGA, and the corona proteins were analyzed with SDS-PAGE. A good correlation between SDS-PAGE and TG results in terms of total amounts of proteins adsorbed was established. The results demonstrated that more proteins, especially apolipoproteins, were associated with the particles at higher serum concentration regardless of surface chem. and morphol. differences. Also, the mean mol. weight of the adsorbed proteins was clearly lower under full serum conditions modeling in vivo conditions as compared to under dilute conditions modeling in vitro conditions, but functionalization of the MSNs by carboxylic acid functionalities reduced protein adsorption. The influence of the structural characteristics of the MSNs on the protein adsorption was minor.

Interactions among the oppositely charged polymer and surfactant are significantly complex in comparison to the interaction between an ionic surfactant and nonionic polymer vis-a-vis the physicochem. properties of the resulting polymer-surfactant solutions In this work, we have deliberated upon the interactions taking place in between a water-soluble anionic polymer, sodium alginate (SA), with a cationic amphiphile, hexadecylbenzyldimethylammonium chloride (C16BzCl), in absence and in presence of sodiumchloride (NaCl) and sodium salicylate (NaSl) employing tensiometric, conductometric, and rheometric measurements. The system was characterized by evaluating physicochem. properties like viscosity curves, critical aggregation concentration (cac), and critical micelle concentration (cmc) as a function of C16BzCl concentration The results show significant differences between the ions furnished by NaCl and NaS1 which could be justified on the basis of effect of solubilization, differential binding of NaSl to polymeric backbone, electrolyte effect, and the solvent modifying tendencies in contrast to the only salt effect of NaCl.
