Surface tension of the oppositely charged sodium poly(styrene sulfonate) /benzyldimethylhexadecylammonium chloride and sodium poly(styrene sulfonate)/polyallylamine hydrochloride mixtures was written by Owiwe, Mina T.;Ayyad, Ahmed H.;Takrori, Fahed M.. And the article was included in Colloid and Polymer Science in 2020.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

Oppositely charged polyelectrolyte/surfactant and the coacervate polyanion/polycation mixtures are known to display complex properties at water/air interface which are not fully elucidated. The change in surface tension of the anionic polyelectrolyte sodium poly(styrene sulfonate) (NaPSS) with either benzyldimethylhexadecylammonium chloride (BAC) as the cationic surfactant or the cationic polyelectrolyte polyallylamine hydrochloride (PAACl) as a function of temperature and added salts was investigated. Neither of the pure polyelectrolytes showed significant surface activity; however, addition of oppositely charged surfactant or polyelectrolyte to varying concentrations of NaPSS solutions had changed the surface activity drastically. The surface tension of the NaPSS/BAC complex is lower than that of pure BAC surfactant. The surface tension of these complexes showed significant decrease with increasing temperatures and the surface excess entropy was deduced from these measurements. Addition of ionic salts enhanced the association of the polyelectrolyte/surfactant mixture but had little effect on the polyelectrolytes coacervate. The surface tension of low concentrations of NaPSS/PAACl coacervate displayed a peak which can be attributed to charge inversion. Graphical abstract [graphic not available: see fulltext].

As a biodegradable polymeric material, the polylactic acid (PLA) has broad applications resulting from its various advantages and unique characteristics. Nevertheless, the application of PLA in various fields is greatly limited by its high flammability. Our recent effort focuses on the manipulation of benzyldimethylhexadecylammonium chloride (HDBAC) modified titanium carbide (Ti3C2T_x) ultra-thin nanosheets which are then used to improve the fire safety of PLA composites filled with silicon microencapsulated ammonium polyphosphate (SiAPP). The flame retardant evaluation showed that when 2.0 wt% HDBAC modified Ti3C2T_x (HDBAC-Ti3C2T_x) and 13.0 wt% SiAPP were added, the LOI value was increased to 33.3%, and the UL-94 V-0 level was obtained, besides the peak heat release rate, total heat release, peak smoke production rate and total smoke release decreased by 49.8%, 31.9%, 60.3% and 52.7%, resp. The barrier and catalytic effects of the modified Ti3C2T_x nanosheets together with the subsequently formed TiO₂ and phosphorus-containing species forming intact expanded carbon layers and interrupting the combustion route are responsible for remarkably improving flame retardancy and suppressing toxic gases of PLA. This work provides a new approach for greatly reducing the fire hazard of PLA.

Formation of drug-participating catanionic aggregates for extended delivery of non-steroidal anti-inflammatory drugs from contact lenses was written by Torres-Luna, Cesar;Koolivand, Abdollah;Fan, Xin;Agrawal, Niti R.;Hu, Naiping;Zhu, Yuli;Domszy, Roman;Briber, Robert M.;Wang, Nam Sun;Yang, Arthur. And the article was included in Biomolecules in 2019.Category: chlorides-buliding-blocks The following contents are mentioned in the article:

This paper focuses on extending drug release duration from contact lenses by incorporating catanionic aggregates. The aggregates consist of a long-chain cationic surfactant, i.e., cetalkonium chloride (CKC), and an oppositely charged anti-inflammatory amphiphilic drug. We studied three non-steroidal anti-inflammatory (NSAID) drugs with different octanol-water partition coefficients; diclofenac sodium (DFNa), flurbiprofen sodium (FBNa), and naproxen sodium (NPNa). Confirmation of catanionic aggregate formation in solution was determined by steady and dynamic shear rheol. measurements. We observed the increased viscosity, shear thinning, and viscoelastic behavior characteristic of wormlike micelles; the rheol. data are reasonably well described using a Maxwellian fluid model with a single relaxation time. In vitro release experiments demonstrated that the extension in the drug release time is dependent on the ability of a drug to form viscoelastic catanionic aggregates. Such aggregates retard the diffusive transport of drug mols. from the contact lenses. Our study revealed that the release kinetics depends on the CKC concentration and the alkyl chain length of the cationic surfactant. We demonstrated that more hydrophobic drugs such as diclofenac sodium show a more extended release than less hydrophobic drugs such as naproxen sodium.

Enhancement of Hot Electron Generation in Colloidal Plasmonic Nanocrystals by Adsorption of Pt Clusters was written by Yang, Yi;Wang, Kaiyu;Khan, Majid;Hu, Ningneng;Ni, Weihai. And the article was included in Advanced Optical Materials in 2022.Product Details of 122-18-9 The following contents are mentioned in the article:

Surface scattering of electrons is used to be recognized as a detrimental damping process of the plasmonic oscillation, whereas such electron-surface scattering generates hot electrons (HEs) inside the metal nanocrystals, being of great significance in practical applications, i.e., photodetection or photocatalytic reactions. However, utilizing surface scattering in colloidal plasmonic nanocrystals in realistic catalytic reactions remains challenging. This work presents a systematic study on the HE rates of colloidal Au nanocrystals, including nanospheres, nanocubes, and nanorods, and their enhancement from the adsorption of Pt clusters. Au nanocubes exhibit the highest single particle-averaged incident photon-to-electron conversion efficiency among the three types of the nanocrystals. The Au nanocrystals are further adsorbed with Pt clusters, and the highest photocurrent enhancement by nearly one order of magnitude is observed To explain the exptl. observations, the contribution of the Pt adsorption to the plasmon damping is characterized by single-particle dark-field spectroscopy, and the HE rates are calculated by employing the finite-element method. The overall significant enhancement of the photocurrent due to the Pt adsorption is finally explained by both electromagnetic and catalytic effects of the Pt clusters.

Ultrafast dynamics of ionic liquids in colloidal dispersion was written by Ren, Zhe;Kelly, Jordan;Gunathilaka, C.

And the article was included in Physical Chemistry Chemical Physics in 2017.Application In Synthesis of N-Benzyl-N,N-dimethylhexadecan-1-aminium chloride The following contents are mentioned in the article:

Ionic liquid (IL)-surfactant complexes have significance both in applications and fundamental research, but their underlying dynamics are not well understood. The authors apply polarization-controlled two-dimensional IR spectroscopy (2D-IR) to study the dynamics of [BMIM][SCN]/surfactant/solvent model systems. The authors examine the effect of the choice of surfactants and solvent, and the IL-to-surfactant ratio (W-value), with a detailed anal. of the orientation and structural dynamics of each system. Different surfactants create very different environments for the entrapped ILs, ranging from a semi-static micro-environment to a fluxional environment that evolves even faster than the bulk IL. The oil-phase also clearly affects the microscopic dynamics. The anisotropy decay for entrapped ILs completes within 10 ps, which is similar to free thiocyanate ion in water, while a significant reorientation-induced spectral diffusion (RISD) effect is observed The entrapped ionic liquid are highly dynamic for all W-values, and no core-shell structure is observed Authors hypothesize that, instead of an ionic liquid-reverse micelle (IL-RM), the microscopic structure of this system is small colloidal dispersions or pairs of IL and surfactants. A detailed anal. of the polarization-controlled 2D-IR spectra of AOT system reveals a potential ion-exchange mechanism.

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.

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.

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.

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.

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.

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
