In this article, a series of pH regulated surfactants with different hydrophobic chain length and carboxyl group mol. structure positions were designed and synthesized. The mol. structure of pH regulated surfactants was analyzed by mass spectrometry and ¹H NMR spectroscopy. The results of the surface activity test show that the pH regulated surfactants have lower surface tension, which indicates that it is easier to adsorb directionally at the gas-liquid interface and to aggregate in solution Both inorganic and organic counterions can improve the viscosity of the system to some extent, but the viscosity-increasing ability of organic counterions is much higher than that of inorganic counterions. The results of rheol. and dynamic light scattering show the transition from spherical micelles to wormlike micelles was observed when pH increased from 5 to 8 in the Docos-13-enoylamino-acetic acid (Gly-22)/Trimethylstearylammonium chioride (ODAC) system. The results of Cryo-transmission electron microscopy verify this result directly. Also, the exptl. results show that the Gly-22/ODAC system has excellent pH cycle regulation performance, which can significantly reduce the application cost of the system. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Application of 122-18-9).

N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides. Chlorination modifies the physical properties of hydrocarbons in several ways. These compounds are typically denser than water due to the higher atomic weight of chlorine versus hydrogen. Organochlorine compounds are lipophylic, meaning they are more soluble in fat than in water. This gives them a high tenancy to accumulate in the food chain (biomagnification).Application of 122-18-9

Sonochemical degradation of surfactants with different charge types: Effect of the critical micelle concentration in the interfacial region of the cavity was written by Nanzai, Ben;Suzuki, Seiya;Okitsu, Kenji. And the article was included in Ultrasonics Sonochemistry in 2021.Recommanded Product: 122-18-9 The following contents are mentioned in the article:

Ionic surfactants tend to accumulate in the interfacial region of ultrasonic cavitation bubbles (cavities) because of their surface active properties and because they are difficult to evaporate in cavitation bubbles owing to their extremely low volatilities. Hence, sonolysis of ionic surfactants is expected to occur in the interfacial region of the cavity. In this study, we performed sonochem. degradation of surfactants with different charge types: anionic, cationic, zwitterionic, and nonionic. We then estimated the degradation rates of the surfactants to clarify the surfactant behavior in the interfacial region of cavitation bubbles. For all of the surfactants investigated, the degradation rate increased with increasing initial bulk concentration and reached a maximum value. The initial bulk concentration to obtain the maximum degradation rate had a pos. correlation with the critical micelle concentration (cmc). The initial bulk concentrations of the anionic surfactants were lower than their cmcs, while those of the cationic surfactants were higher than their cmcs. These results can be explained by the neg. charged cavity surface and the effect of the coexisting counterions of the surfactants. 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).

N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides.

The haloform reaction, using chlorine and sodium hydroxide, is also able to generate alkyl halides from methyl ketones, and related compounds. Chloroform was formerly produced thus.Recommanded Product: 122-18-9

Building of hierarchical structure of functionalized montmorillonite anchored with ZnO: Toward fabricating high-performance polyethylene composite was written by Wang, Junling;Wang, Bibo;Ma, Chao;Xiao, Yuling;Guo, Wenwen;Cai, Wei;Song, Lei;Wang, Xin;Hu, Yuan. And the article was included in Applied Clay Science in 2020.Application of 122-18-9 The following contents are mentioned in the article:

As is well known, polyethylene (PE) is flammable with the release of abundant heat, confirming its low fire safety. Consequently, the extended application of PE is restrained. In this work, we propose the facile preparation of multi-component hybrid (functionalized montmorillonite anchored with ZnO, defined as FMZH) and its promising utilization in PE. With the aid of functionalized compound, the obtained hybrid shows good dispersion state, as well as strong interfacial interaction with polymer matrix. By incorporating FMZH fillers, the marked reductions in peak heat release rate (PHRR) and total heat release (THR) can be obtained, corroborating the enhanced fire safety. Specifically, with the addition of 5.0 wt% 1-2FMZH and 1-4FMZH, the PHRR values are reduced to 567 and 667 kW/m2, resp., corresponding to 54.7 and 46.8% decrease. Also, the suppressing effect on the release of decomposition fragments can be evidenced by the decreased absorbance intensity in FTIR spectra. Furthermore, the presence of these fillers shows marginal influence on the nonisothermal crystallization behavior of PE. Addnl., the FMZH composite with hierarchical structure shows superior gas barrier function over pristine ZnO and montmorillonite.

Valence, Size, and Shape Control of Gold Nanoparticles Synthesized by Electron-Assisted Reduction was written by Shi, Mengge;Wang, Zhao. And the article was included in Chemistry – An Asian Journal in 2020.SDS of cas: 122-18-9 The following contents are mentioned in the article:

An electron-assisted strategy was developed to prepare Au nanoparticles (AuNPs) at room temperature Glow discharge plasma as electron source was successfully used to control the valence state, size, and shape of AuNPs. Stable Au(I) was obtained in 3 min by plasma, and Au(I) was reduced to zero valence with the increase in treatment time. An increase in the amount of Au did not induce an increase in particle size. A narrow size distribution was also achieved. The narrowest size distribution was observed at 9 min at 600 V. AuNPs grew slowly under glow discharge plasma, which slightly changed the mean size of AuNPs. Also, the average size of AuNPs was smaller under alk. conditions. The initial pH of the solution can affect the nucleation and growth of AuNPs and further affect their particle size. Spherical AuNPs, hexagonal AuNPs, rectangular AuNPs, flower-shaped AuNPs, and Au nanorods were easily obtained within 30 min by adding different additives. The hexagonal AuNPs exhibited the largest current response toward caffeine and showed a good linear range (0.1-1000μM) with a low detection limit (0.064μM), because their high-energy planes can increase the electron transfer rate and improve electrocatalytic activity.

ZnO nanostructures with antibacterial properties prepared by a green electrochemical-thermal approach was written by Sportelli, Maria Chiara;Picca, Rosaria Anna;Izzi, Margherita;Palazzo, Gerardo;Gristina, Roberto;Innocenti, Massimo;Torsi, Luisa;Cioffi, Nicola. And the article was included in Nanomaterials in 2020.Reference of 122-18-9 The following contents are mentioned in the article:

Zinc oxide (ZnO) nanostructures are widely applied materials, and are also capable of antimicrobial action. They can be obtained by several methods, which include phys. and chem. approaches. Considering the recent rise of green and low-cost synthetic routes for nanomaterial development, electrochem. techniques represent a valid alternative to biogenic synthesis. Following a hybrid electrochem.-thermal method modified by our group, here we report on the aqueous electrosynthesis of ZnO nanomaterials based on the use of alternative stabilizers. We tested both benzyl-hexadecyl-dimetylammonium chloride (BAC) and poly-diallyl-(dimethylammonium) chloride (PDDA). Transmission electron microscopy images showed the formation of rod-like and flower-like structures with a variable aspect-ratio. The combination of UV-Vis, FTIR and XPS spectroscopies allowed for the univocal assessment of the material composition as a function of different thermal treatments. In fact, the latter guaranteed the complete conversion of the as-prepared colloidal materials into stoichiometric ZnO species without excessive morphol. modification. The antimicrobial efficacy of both materials was tested against Bacillus subtilis as a Gram-pos. model microorganism. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Reference of 122-18-9).

Investigation on interaction of DNA and several cationic surfactants with different head groups by spectroscopy, gel electrophoresis and viscosity technologies was written by Guo, Qing;Zhang, Zhaohong;Song, Youtao;Liu, Shuo;Gao, Wei;Qiao, Heng;Guo, Lili;Wang, Jun. And the article was included in Chemosphere in 2017.Name: N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

In this study, the interaction between DNA and several cationic surfactants with different head groups such as Et hexadecyl di-Me ammonium bromide (EHDAB), hexadecyl di-Me benzyl ammonium chloride (HDBAC), and cetyl pyridinium bromide (CPB) were investigated by UV-vis absorption, fluorescence and CD (CD) spectroscopy, gel electrophoresis, and viscosity technologies. The results show that these cationic surfactants can interact with DNA and major binding modes are electrostatic and hydrophobic. Also, CPB and HDBAC mols. interact with DNA by partial intercalation, and CPB has slightly stronger intercalation than HDBAC, while EHDAB interacts with DNA by non-intercalation. The different head groups of the surfactant mols. can influence the interaction strength. CPB has the stronger interaction with DNA than the others. Moreover, surfactant concentration, the ratio of DNA and fluorescence probe, ionic strength can influence the interaction. The surfactants may interact with DNA by the competition reactions with BR for DNA-BR. The increase of ionic strength may favor the surface binding between DNA and surfactants to some extent. This work provides deep mechanistic insight on the toxicity of cationic surfactants with different head groups to DNA mols.

Fluorographene as a Mass Spectrometry Probe for High-Throughput Identification and Screening of Emerging Chemical Contaminants in Complex Samples was written by Huang, Xiu;Liu, Qian;Huang, Xiaoyu;Nie, Zhou;Ruan, Ting;Du, Yuguo;Jiang, Guibin. And the article was included in Analytical Chemistry (Washington, DC, United States) in 2017.Application In Synthesis of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

Mass spectrometry techniques for high-throughput anal. of complex samples are of profound importance in many areas such as food safety, omics studies, and environmental health science. Here the authors report the use of fluorographene (FG) as a new mass spectrometry probe for high-throughput identification and screening of emerging chem. contaminants in complex samples. FG was facilely synthesized by 1-step exfoliation of fluorographite. With FG as a matrix or probe in matrix-assisted or surface-enhanced laser desorption/ionization time-of-flight mass spectrometry (MALDI- or SELDI-TOF MS), higher sensitivity (detection limits at ppt or subppt levels), and better reproducibility were achieved than with other graphene-based materials due to the unique chem. structure and self-assembly properties of FG. The method was validated with different types of real complex samples. By using FG as a SELDI probe, the authors could easily detect trace amount of bisphenol S in paper products and high-fat canned food samples. Also, the authors have successfully identified and screened as many as 28 quaternary ammonium halides in sewage sludge samples collected from municipal wastewater treatment plants. FG probe is a powerful tool for high-throughput anal. of complex samples by MS.

And the article was included in Environmental Science & Technology in 2021.Recommanded Product: 122-18-9 The following contents are mentioned in the article:

Quaternary ammonium compounds (QACs) are commonly used in a variety of consumer, pharmaceutical, and medical products. In this study, bioaccumulation potentials of 18 QACs with alkyl chain lengths of C8-C18 were determined in the in vitro-in vivo extrapolation (IVIVE) model using the results of human hepatic metabolism and serum protein binding experiments The slowest in vivo clearance rates were estimated for C12-QACs, suggesting that these compounds may preferentially build up in blood. The bioaccumulation of QACs was further confirmed by the anal. of human blood (sera) samples (n = 222). Fifteen out of the 18 targeted QACs were detected in blood with the ΣQAC concentrations reaching up to 68.6 ng/mL. The blood samples were collected during two distinct time periods: before the outbreak of the COVID-19 pandemic (2019; n = 111) and during the pandemic (2020, n = 111). The ΣQAC concentrations were significantly higher in samples collected during the pandemic (median 6.04 ng/mL) than in those collected before (median 3.41 ng/mL). This is the first comprehensive study on the bioaccumulation and biomonitoring of the three major QAC groups and our results provide valuable information for future epidemiol., toxicol., and risk assessment studies targeting these chems.

Surface chemistry interactions of cationorm with films by human meibum and tear film compounds was written by Georgiev, Georgi As.;Yokoi, Norihiko;Nencheva, Yana;Peev, Nikola;Daull, Philippe. And the article was included in International Journal of Molecular Sciences in 2017.Name: N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

Cationorm (CN) cationic nanoemulsion was demonstrated to enhance tear film (TF) stability in vivo possibly via effects on tear film lipid layer (TFLL). Therefore the interactions of CN with human meibum (MGS) and TFLL in vitro and in vivo deserve special study. MGS and CN were spread at the air/water interface of a Langmuir surface balance to ensure a range of MGS/CN oil phase ratios: 20/1, 10/1, 5/1, 3/1, 2/1 and 1/1. The films capability to reorganize during dynamic area changes was evaluated via the surface pressure-area compression isotherms and step/relaxation dilatational rheol. studies. Films structure was monitored with Brewster angle microscopy. CN/TFLL interactions at the ocular surface were monitored with non-contact specular microscopy. The in vitro studies of MGS/CN layers showed that (i) CN inclusion (at fixed MGS content) increased film elasticity and thickness and that (ii) CN can compensate for moderate meibum deficiency in MGS/CN films. In vivo CN mixed with TFLL in a manner similar to CN/MGS interactions in vitro, and resulted in enhanced thickness of TFLL. In vitro and in vivo data complement each other and facilitated the study of the composition-structure-function relationship that determines the impact of cationic nanoemulsions on TF. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Name: N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride).

A simple one-step procedure to synthesise gold nanostars in concentrated aqueous surfactant solutions was written by Liebig, Ferenc;Henning, Ricky;Sarhan, Radwan M.;Prietzel, Claudia;Schmitt, Clemens N. Z.;Bargheer, Matias;Koetz, Joachim. And the article was included in RSC Advances in 2019.Safety of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

Due to the enhanced electromagnetic field at the tips of metal nanoparticles, the spiked structure of gold nanostars (AuNSs) is promising for surface-enhanced Raman scattering (SERS). Therefore, the challenge is the synthesis of well designed particles with sharp tips. The influence of different surfactants, i.e., dioctyl sodium sulfosuccinate (AOT), sodium dodecyl sulfate (SDS), and benzylhexadecyldimethylammonium chloride (BDAC), as well as the combination of surfactant mixtures on the formation of nanostars in the presence of Ag⁺ ions and ascorbic acid was investigated. By varying the amount of BDAC in mixed micelles the core/spike-shell morphol. of the resulting AuNSs can be tuned from small cores to large ones with sharp and large spikes. The concomitant red-shift in the absorption toward the NIR region without losing the SERS enhancement enables their use for biol. applications and for time-resolved spectroscopic studies of chem. reactions, which require a permanent supply with a fresh and homogeneous solution HRTEM micrographs and energy-dispersive X-ray (EDX) experiments allow us to verify the mechanism of nanostar formation according to the silver underpotential deposition on the spike surface in combination with micelle adsorption.
