And the article was included in Journal of the American Chemical Society in 2018.COA of Formula: C25H46ClN The following contents are mentioned in the article:

Novel mesostructured silica microparticles are synthesized, characterized, and investigated as a drug delivery system (DDS) for antimicrobial applications. The materials exhibit a relatively high d. (0.56 g per 1 g SiO₂) of benzalkonium chloride (BAC), pore channels of 18 Å in width, and a high surface area (1500 m²/g). Comparison of the small-angle X-ray diffraction (SAXRD) pattern with Barrett-Joyner-Halenda (BJH) pore size distribution data suggests that the 18 Å pores exhibit short-range ordering and a wall thickness of ca. 12 Å. Drug release studies demonstrate pH-responsive controlled release of BAC without addnl. surface modification of the materials. Prolonged drug release data were analyzed using a power law (Korsmeyer-Peppas) model and indicate substantial differences in release mechanism in acidic (pH 4.0, 5.0, 6.5) vs. neutral (pH 7.4) solutions Microbiol. assays demonstrate a significant time-dependent reduction in Staphylococcus aureus and Salmonella enterica viability above 10 and 130 mg L^-1 of the synthesized materials, resp. The viability of cells is reduced over time compared to control samples. The findings will help in widening the use of BAC as a disinfectant and bactericidal agent, especially in pharmaceutical and food industries where Gram-pos. and Gram-neg. bacterial contamination is common. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9COA of Formula: C25H46ClN).

N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides. Organic chlorides can cause corrosion in pipelines, valves and condensers, and cause catalyst poisoning. The hydrocarbon processing industry (HPI) and others are affected by damage caused by these substances. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.COA of Formula: C25H46ClN

Nanorattles with tailored electric field enhancement was written by Schnepf, Max J.;Mayer, Martin;Kuttner, Christian;Tebbe, Moritz;Wolf, Daniel;Dulle, Martin;Altantzis, Thomas;Formanek, Petr;Foerster, Stephan;Bals, Sara;Koenig, Tobias A. F.;Fery, Andreas. And the article was included in Nanoscale in 2017.Related Products of 122-18-9 The following contents are mentioned in the article:

Nanorattles are metallic core-shell particles with core and shell separated by a dielec. spacer. These nanorattles have been identified as a promising class of nanoparticles, due to their extraordinary high elec.-field enhancement inside the cavity. Limiting factors are reproducibility and loss of axial symmetry owing to the movable metal core; movement of the core results in fluctuation of the nanocavity dimensions and commensurate variations in enhancement factor. We present a novel synthetic approach for the robust fixation of the central gold rod within a well-defined box, which results in an axisym. nanorattle. We determine the structure of the resulting axisym. nanorattles by advanced transmission electron microscopy (TEM) and small-angle X-ray scattering (SAXS). Optical absorption and scattering cross-sections obtained from UV-vis-NIR spectroscopy quant. agree with finite-difference time-domain (FDTD) simulations based on the structural model derived from SAXS. The predictions of high and homogenous field enhancement are evidenced by scanning TEM electron energy loss spectroscopy (STEM-EELS) measurement on single-particle level. Thus, comprehensive understanding of structural and optical properties is achieved for this class of nanoparticles, paving the way for photonic applications where a defined and robust unit cell is crucial. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Related Products 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. Aryl chlorides may be prepared by the Friedel-Crafts halogenation, using chlorine and a Lewis acid catalyst.Related Products of 122-18-9

Screening of biocides, metals and antibiotics in Swedish sewage sludge and wastewater was written by Oestman, Marcus;Lindberg, Richard H.;Fick, Jerker;Bjoern, Erik;Tysklind, Mats. And the article was included in Water Research in 2017.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

Incoming sewage water, treated effluent and digested sludge were collected from 11 Swedish sewage treatment plants (STPs) on 3 different days. Anal. protocols were established for a large number of compounds (47) with antimicrobial properties and the collected samples were then screened for the presence of these selected substances. Liquid chromatog. tandem mass spectrometry (LC-MS/MS) and inductively coupled plasma mass spectrometry (ICP-MS) were used to analyze the samples. Thirty organic compounds and 10 metals were detected above their resp. detection limit. Quaternary ammonium compounds were the most abundant substances in the particulate phases with levels up to 370 μg/g and benzotriazoles were the most common in the aqueous phases with levels up to 24 μg/L. Several compounds with no, or very limited, previously reported data were detected in this study, including chlorhexidine, hexadecylpyridinium chloride and 10-benzalkonium chloride. Some of these were both frequently detected (>60% detection frequency) and found in high levels (up to 19 μg/g d.w. sludge). This study gives a comprehensive overview of the presence in Swedish STPs of a number of antimicrobial substances, providing crucial information in designing relevant studies on potential microbial co- and cross resistance development between antibiotics, biocides, and metals in the sewage system.

Adsorption of benzalkonium chlorides onto polyethylene microplastics: Mechanism and toxicity evaluation was written by Kim, Tae-Kyoung;Jang, Minhee;Hwang, Yu Sik. And the article was included in Journal of Hazardous Materials in 2022.Electric Literature of C25H46ClN The following contents are mentioned in the article:

Usage of disposable plastic products and disinfectants has been skyrocketing due to the COVID-19 pandemic. The random disposal of plastic products may result in greater microplastic pollution. Benzalkonium chloride is known as one of the most common ingredients of disinfectants. In this study, the adsorption behavior of benzalkonium chlorides (BAC₁₂, BAC₁₄, BAC₁₆) on polyethylene microplastics (PE-MPs) and the combined toxic effects were investigated using batch adsorption experiment and Daphnia magna. PE-MPs had strong adsorption capacity for BACs and the adsorption capacity increased (11.03-22.77 mg/g) with their octanol-water distribution coefficients The effect of pH was negligible while dissolved organic matter inhibited the adsorption. A slightly inverse relation between particle size of PE-MPs and adsorption was observed Addnl., the MP aging with UV/H₂O₂ increased the adsorption of BAC₁₂ but decreased that of relatively hydrophobic BAC₁₄ and BAC₁₆. The survival rate of Daphnia magna increased ≤100% in the presence of PE-MPs depending upon their adsorption capacities, suggesting that PE-MPs do not act as a carrier but rather as a scavenger for BACs. This study provides important information necessary for environmental risk assessment with regard to the combined pollution of MPs and toxic chems. This study involved multiple reactions and reactants, such as N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9Electric Literature of C25H46ClN).

N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride (cas: 122-18-9) belongs to organic chlorides. An organic chloride is an organic compound containing at least one covalently bonded atom of chlorine. Their wide structural variety and divergent chemical properties lead to a broad range of names and applications. Alkanes and aryl alkanes may be chlorinated under free radical conditions, with UV light. However, the extent of chlorination is difficult to control.Electric Literature of C25H46ClN

Development and application of retention time prediction models in the suspect and non-target screening of emerging contaminants was written by Aalizadeh, Reza;Nika, Maria-Christina;Thomaidis, Nikolaos S.. And the article was included in Journal of Hazardous Materials in 2019.Application of 122-18-9 The following contents are mentioned in the article:

Hydrophilic interaction liquid chromatog. (HILIC) and reversed phase LC (RPLC) coupled to high resolution mass spectrometry (HRMS) are widely used for the identification of suspects and unknown compounds in the environment. For the identification of unknowns, apart from mass accuracy and isotopic fitting, retention time (t_R) and MS/MS spectra evaluation is required. In this context, a novel comprehensive workflow was developed to study the t_R behavior of large groups of emerging contaminants using Quant. Structure-Retention Relationships (QSRR). 682 compounds were analyzed by HILIC-HRMS in pos. Electrospray Ionization mode (ESI). Moreover, an extensive dataset was built for RPLC-HRMS including 1830 and 308 compounds for pos. and neg. ESI, resp. Support Vector Machines (SVM) was used to model the t_R data. The applicability domains of the models were studied by Monte Carlo Sampling (MCS) methods. The MCS method was also used to calculate the acceptable error windows for the predicted t_R from various LC conditions. This paper provides validated models for predicting t_R in HILIC/RPLC-HRMS platforms to facilitate identification of new emerging contaminants by suspect and non-target HRMS screening, and were applied for the identification of transformation products (TPs) of emerging contaminants and biocides in wastewater and sludge. 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. Organochlorines stimulate the central nervous system and cause convulsions, tremor, nausea, and mental confusion. Examples are dichlorodiphenyltrichloroethane (DDT), chlordane, lindane, endosulfan, and dieldrin. 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

Patterning Metal Nanowire-Based Transparent Electrodes by Seed Particle Printing was written by Layani-Tzadka, Muriel E.;Tirosh, Einat;Markovich, Gil. And the article was included in ACS Omega in 2017.Name: N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

This paper describes a unique combination of ink jet printing of functional materials with an intricate self-assembly process. Gold-silver nanowire (NW) mesh films were produced by a sequential deposition process, in which small metal seed nanoparticle film was deposited at desired areas by ink jet printing, followed by coating with a thin-film of NW growth solution Two different types of NW growth solutions were used: the first, based on BDAC (benzylhexadecyldimethylammonium chloride), exhibited bulk solution growth mode and was thus suitable for coverage of large uniform areas. The second type was based on CTAB (hexadecyltrimethylammonium bromide), which induced NW growth confined to the substrate solution interface and thus enabled patterning of small transparent electrode features, which have the same dimensions as the deposited seed droplets. A selective silver plating bath was used to thicken the ultrathin NWs, to stabilize them, and reduce the sheet resistance, resulting in films with sheet resistance in the range of 20-300 Ω/sq., with 86-95% light transmission and relatively low haze. This simple patterning method of the NW film works at ambient conditions on many different types of substrates and has the potential to replace conventional photolithog. used for indium tin oxide (ITO) patterning for applications such as touch sensors and flexible/stretchable electronics. 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).

Cyanuric chloride-imidazole dendrimer functionalized nanoparticles as an adsorbent for magnetic solid phase extraction of quaternary ammonium compounds from fruit and vegetable puree based infant foods was written by Zhao, Tangjuan;Zhang, Mengyan;Ma, Ling;Ma, Li;Shi, Hongmei;Kang, Weijun;Xu, Xiangdong. And the article was included in Journal of Chromatography A in 2021.Recommanded Product: 122-18-9 The following contents are mentioned in the article:

A novel magnetic solid-phase extraction (MSPE) material (Fe3O4@SiO2-NH2-G2) had been prepared and employed for adsorption and anal. of seven quaternary ammonium compounds (QACs) in infant fruit and vegetable products coupled with high performance liquid chromatog. tandem mass spectrometry (HPLC-MS/MS). In this paper, Fe3O4@SiO2-NH2-G2 was synthesized based on Fe3O4@SiO2-NH2 and dendrimer (G2) consisting of cyanuric chloride and imidazole. The morphol., configuration and magnetic behavior of the magnetic material were characterized by transmission electron microscopy (TEM), Fourier transform IR spectrometry (FT-IR), X-ray diffraction (XRD), and vibrating sample magnetometer (VSM). Critical parameters affecting extraction efficiency, such as the adsorbent amount, sample pH, extraction time, the type of eluent, and desorption time, were optimized. The proposed method provided good linearity with the correlation coefficients (R2) of 0.9992-0.9999, low limits of detection (LODs) (0.05-0.50μg kg-1) and limits of quantitation (LOQs) (0.20-2.00μg kg-1). The satisfactory method recoveries in three spiked infant fruit and vegetable products samples were between 80.12% and 101.35% with the relative standard deviations (RSDs) less than 12.04%. In summary, the established method was an effective sample preparation method and showed good prospect for the anal. of QACs in complex matrixes.

Two-dimensional 16-BAC/SDS polyacrylamide gel electrophoresis of mitochondrial membrane proteins was written by Smejkal, Gary;Kakumanu, Srikanth. And the article was included in Methods in Molecular Biology in 2019.Name: N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

The substitution of the reverse polarity benzyldimethyl-n-hexadecylammonium chloride (16-BAC) polyacrylamide gel electrophoresis (PAGE) for isoelec. focusing (IEF) in the first dimension of electrophoresis improves the solubility of extremely hydrophobic proteins and their recovery compared to conventional 2D IEF/SDS PAGE. The acidic environment of 16-BAC PAGE has also been shown to better preserve the labile methylation of basic proteins such as the histones. Several improvements of the 2D 16-BAC/SDS PAGE method are collectively described here with particular emphasis on the separation of mitochondrial membrane proteins of low mol. mass. Lowering the 16-BAC concentration 50-fold in the gel and buffers decreases the formation of mixed 16-BAC/SDS micelles, which otherwise interferes with the separation of very low mol. mass proteins in second dimension SDS PAGE, and consequently improved the resolution of mitochondrial membrane proteins in the 10-30 kDa range.

Tuned Surface-Enhanced Raman Scattering Performance of Undulated Au@Ag Triangles was written by Liebig, Ferenc;Sarhan, Radwan M.;Prietzel, Claudia;Schmitt, Clemens N. Z.;Bargheer, Matias;Koetz, Joachim. And the article was included in ACS Applied Nano Materials in 2018.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

Neg. charged ultraflat gold nanotriangles (AuNTs) stabilized by the anionic surfactant dioctyl sodium sulfosuccinate (AOT) were reloaded with the cationic surfactant benzylhexadecyldimethylammonium chloride (BDAC). Because of the spontaneous formation of a catanionic AOT micelle/BDAC bilayer onto the surface of the reloaded AuNTs, a reduction of Ag⁺ ions leads to the formation of spherical silver nanoparticles (AgNPs). With increasing concentration of AgNPs on the AuNTs, the localized surface plasmon resonance (LSPR) is shifted stepwise from 1300 to 800 nm. The tunable LSPR enables to shift the extinction maximum to the wavelength of the excitation laser of the Raman microscope at 785 nm. Surface-enhanced Raman scattering (SERS) experiments performed under resonance conditions show an SERS enhancement factor of the analyte mol. rhodamine RG6 of 5.1 × 10⁵, which can be related to the silver hot spots at the periphery of the undulated gold nanoplatelets.

IR plasmonic nanoantennas are key building blocks in nanotechnol. By coupling and confining light into spatial volumes below the diffraction limit, IR plasmonic nanoantennas provide unique opportunities to sense and signal at nanometer length scales for energy harvesting, as light sources, and in nanomedicine applications. However, in contrast to their radio- and microwave counterparts, widespread use of plasmonic nanoantennas has been limited, due in part to the inability to synthesize these structures maintaining nanoscale precision in large batches with uniform yields. This communication describes a directed assembly approach to generate large quantities of IR plasmonic nanoantennas with sharp and widely tunable absorption peaks from 1 to 3 μm. It is exptl. demonstrated that the nanoantenna absorption peak depends linearly on the chain length, in agreement with simulations, providing a straightforward means to understand and predict the IR response of these materials.
