Broadening the polarity range of polymer-based aqueous two-phase systems (ATPSs) is of practical significance. Recently, ionic liquids have been used as adjuvants to modify the polarity and properties of PEG-rich phases in PEG/salt ATPSs. However, thus far, only short alkyl (containing less than 8 carbon atoms)-chained ionic liquids have been able to promote the extraction performance of ATPSs; long alkyl-chained ionic liquids have decreased the extraction performance significantly due to their distribution in the bottom phase. In the present study, we found that by complexing with Triton X-100 (TX-100), long alkyl-chained imidazolium ionic liquids [C n mim]Br (n = 10 and 12) as adjuvants were enriched in the top phase of PEG/salt ATPSs, and hence, the polarity difference of the two phases were increased. By extracting two model substances (S-mandelic acid (MA) and l -tryptophan (Trp)), it was concluded that, although the long alkyl-chained [C n mim]Br adjuvant decreased the extraction performance of the ATPS substantially, the long alkyl-chained [C n mim]Br/TX-100 complex as the adjuvant enhanced the extraction performance of the ATPS significantly. Compared with the case without an adjuvant, when the [C 12 mim]Br/TX-100 complex and the [C 10 mim]Br/TX-100 complex were used as the adjuvants, the partition coefficients of MA and Trp in the PEG 600/(NH 4 ) 2 SO 4 ATPS were increased up to 3 ∼ 4 times, much better than those with short alkyl-chained ionic liquid as the adjuvant. Moreover, the [C 12 mim]Br/TX-100 complex is more conductive to the transfer of MA into the PEG-rich phase, and the [C 10 mim]Br/TX-100 complex is more conductive to the transfer of Trp into the PEG-rich phase.

The effect of intermolecular interaction of Phthalic acid (PA) and nonionic surfactants on electrodeposition was studied and the electrodeposition of tin was used as a model system. The CV curve of the electrolyte in the presence of a combination of PA and Triton X-100 (TX100) indicates that a relatively compact adlayer forms on the electrode surface and the electrodeposition of tin is inhibited very well. It is expected that the aromatic character of the hydrophobic moiety of both TX100 and PA enhance the binding interaction and the blocking effect is governed by the intermolecular interaction between PA and TX100. Scanning electron microscopic (SEM) image shows that a smooth, regular and compact deposit was obtained from the electrolyte with both PA and TX100. A relatively low carbon content of the deposit indicates that the incorporation of the additive in a deposit is strongly controlled in the presence of both PA and TX100. The possible explanation for the reduced incorporation may be proposed as the formation of the linkage of the molecules caused by intermolecular interaction between PA and TX100.

Abstract A new route to synthesis hierarchical Ti-rich TS-1 with uniform intracrystalline mesopores, uniform crystal size and the higher Ti content has been developed by using the environmental-friendly and cheap surfactant Triton X-100 as the assisted template agent and (NH 4 ) 2 CO 3 as crystallization-mediating agent. In this way, the surface area and pore volume of the resulting materials can be adjusted by the Triton X-100 content. The catalytic properties of the Nano-size hierarchical Ti-rich TS-1 were investigated by hydroxylation of benzene to phenol with H 2 O 2 as oxidizing agent and deionized water as solvent. Due to the combination of hierarchical pores and high titanium content, the hierarchical Ti-rich TS-1 shows improved catalytic activity in the oxidation of benzene. Graphical Abstract

Triton X-100 (TX-100) is a commonly used surfactant in the manufacture of biosensors. The factors limiting the use of TX-100 in biosensors are environmental concerns. In this study, the binary system of sodium dodecyl benzene sulfonate (SDBS) and fatty alcohol-polyoxyethlene ether (AEO) was investigated from the physicochemical principle of surfactant interaction and its application in biosensors. The results demonstrated that a mixture of SDBS and AEO at an appropriate molar ratio had a comparable activity to TX-100 in terms of surface activity, micelle formation, dynamic adsorption, foaming, emulsifying, and cell permeability. Theory and experimentation support the idea that SDBS-AEO might take the place of TX-100 in the manufacturing of biosensors. This study contributes to the development of alternatives to TX-100 and provides a new perspective for an in-depth study of the interaction mechanism of additives in biosensor design.

Electromagnetic synergy is a more effective physical method than a single AC electric field (ACEF) to enhance oil–water separation. However, the critical coalescence conditions and transformation mechanism of droplets adsorbing surfactant molecules in the synergistic electromagnetic field (EMSF) still lack research. Herein, a series of Triton X-100-adsorbed droplets with different surface tensions were prepared, and the critical coalescence electric intensity ( E c ) of the droplets under ACEF and EMSF were compared. Micro high-speed experiments revealed that E c of droplets under EMSF is higher than under ACEF. The electric intensity, E c , increased with the increase in interfacial tension γ under both ACEF and EMSF. This study provides valuable results for designing high-performance devices by introducing electromagnetic synergy in water-in-oil emulsion treatment. For the equipment with electromagnetic synergy to strengthen oil–water separation, the allowable optimal voltage should be higher than that of the electrostatic coalescer, and the adjustment range is 2.99%−9.57%.

Nano-scaled polypyrrole (PPy) particles have been successfully synthesized with the help of Triton X-100 micelles via soft template approach. The polypyrrole nanoparticles have been spin-coated on surface acoustic wave (SAW) transducers to demonstrate their sensing capability toward acetone gas exposure. Field Emission Scanning Electron Microscopes (FE-SEM) and Fourier transform infrared (FT-IR) spectroscopy have been utilized to characterize these PPy nanoparticles. The PPy nanoparticles have an average diameter of 95 nm. The responses of the sensors are linearly associated with the acetone concentrations in the range from 5.5 ppm to 80 ppm. In response to 5.5 ppm acetone exposure, the response and recovery time are 9 s and 8.3 s, respectively. SAW sensors coated with PPy nanoparticles were potentially useful to detect acetone.

Nitrogen-doped carbons (NC) and carbon nitride (C 3 N 4 ) belong to the two fundamental pillars of functionalized carbon materials that have broad applications in different fields. The synthesis of NC and C 3 N 4 often starts from different precursors, and a general approach that can offer both architectures is still highly sought. Herein, a facile Triton X-100-assisted copolymerization-carbonization strategy is reported to fulfill this task. By moderating the weight ratios of Triton X-100 and several conventional precursors of C 3 N 4 ( e.g ., dicyandiamide, urea, and cyanamide), a series of both types of N-functionalized carbons with controllable N dopants is successfully afforded. The yielded solids transform from graphitic C 3 N 4 with low surface areas to porous NC when the weight ratio reaches the critical values. This phenomenon might be attributed to the intensified copolymerization between the intermediates of both starting precursors during the carbonization, resulting in increased oxygen content and decreased N:C ratio in the products. Both the bulk and activated carbon-supported materials are then designed and used as metal-free catalysts in the dehydrochlorination of ethylene dichloride, a key reaction in polyvinyl chloride manufacture. It is found that NC is significantly more active than C 3 N 4 , but the corresponding supported catalysts exhibit an opposing trend. The structure-activity correlations suggest both the number of different N defects and the surface areas might play key roles in determining the dehydrochlorination chemistry.

The efficiency of chemical enhanced oil recovery (EOR) is significantly influenced by the adsorption behavior of surfactants on rock surfaces, a phenomenon not fully understood in terms of molecular structuring and interfacial dynamics. In this study, we present a multi-scale investigation that integrates static adsorption experiments, quartz crystal microbalance with dissipation (QCM-D), and molecular dynamics (MD) simulations to elucidate the adsorption characteristics of two representative nonionic and anionic surfactants, Triton X-100 and sodium dodecyl benzene sulfonate (SDBS). Their adsorption capacities followed the order: montmorillonite > calcium carbonate > silicon dioxide. The adsorption isotherm of surfactants on calcium carbonate and silicon dioxide followed the Langmuir model, while adsorption on montmorillonite aligned more with the Freundlich model. Kinetic studies indicated that the adsorption processes for both surfactants followed the pseudo-second-order model. Thermodynamic analysis revealed that the adsorption processes were both exothermic and spontaneous. Notably, QCM-D measurements further confirmed bilayer adsorption structures for both surfactants at the solid-liquid interface. Complementary MD simulations provided molecular-level insights into adsorption energy, conformational arrangement, spatial distribution, and hydrogen bonding networks, revealing distinct interaction mechanisms for the two surfactants. The obtained results offer a comprehensive understanding of surfactant-rock interactions, which are crucial for optimizing chemical flooding processes in EOR applications.

Here, we present a first investigation of the inhibition mechanism of surfactant Triton X-100 (TX-100) on the oxidation degradation of polycyclic aromatic hydrocarbons (PAHs) in site soil aggregates using sodium citrate assisted Fe 2+ -activated persulfate (SC/Fe 2+ /PS). First, TX-100 was not only competed the adsorption sites of soil aggregates with PS, but also consumed PS, which inhibit the PAHs remediation rate in the TX-100 elution followed by the SC/Fe 2+ /PS oxidation system from 55.6% in the oxidation system to 50.3%. Furthermore, in the oxidation followed by elution system, PAHs was adsorbed on the iron minerals produced during the oxidation, which would be form a bound PAHs that was difficult to react with PS, and then re-eluted to the soil by the TX-100. Additionally, it was found that the oxidative and the elution efficiency of PAHs exhibited negative correlations with aggregate particle sizes. Finally, soil microorganism communities were more strongly changed by SC/Fe 2+ /PS oxidation and PAHs concentration than that of TX-100 elution, with obvious alterations bacteria than fungi, the effects of SC/Fe 2+ /PS and PAHs concentration on microorganism communities were opposite. This study provided a proof of regulating mechanisms for the site soil remediation using surfactants combined with the iron-PS system. Environmental Implications Surfactants may have inhibitory effects in advanced oxidative systems on the removal of PAHs and may alter soil microorganism diversity. It is necessary to comprehensively analyze the intrinsic regulatory mechanisms, and the correlation between the remediation process and soil microbial community structure of surfactants affecting the remediation efficiency of PAHs in site soil aggregates. This work comprehensively discussed the controlling mechanisms of surfactants affect the oxidation remediation of PAHs in the site soil and providing new insights for the design of the remediation technologies for the soil polluted with PAHs in the future.

OmpA signal peptide mediated cgt gene from Paenibacillus macerans JFB05-01 was cloned and expressed in E. coli BL21 (DE3). The effects of glycine and Triton X-100 on extracellular production of α-cyclodextrin glycosyltransferase (α-CGTase) were investigated. When supplemented with Gly or Triton X-100 to the culture media individually, the secreted extracellular enzyme reached 32 or 33 U/mL at 48 h of cultivation, respectively. When supplemented with Gly and Triton X-100 together, the extracellular α-CGTase activity reached 48 U/mL after 48 h cultivation, which was 20-fold of the control group without any additives. Analysis of membrane permeability demonstrated that addition of glycine and Triton X-100 enhanced the permeability of both outer and inner membrane. The potential mechanism of the enhanced protein secretion was discussed.

The prevention and treatment of oral diseases is more difficult in diabetic patients with poorly controlled blood glucose levels. This study aims to explore an effective, low-cytotoxicity medication for root canal treatment in diabetic patients. The antibacterial effect of the combination of Triton X-100 (TX-100) and metformin (Met) onEnterococcus faecalis(E. faecalis) was evaluated by determining the minimum inhibitory concentration (MIC), minimum bactericidal concentration required to kill 99% bacteria (MBC99) and by conducting dynamic time-killing assays. While the antibiofilm activity was measured by crystal violet (CV) assay, field emission scanning electron microscope (FE-SEM), confocal laser scanning microscope (CLSM) and colony-forming unit (CFU) counting assays. The expression of relative genes was evaluated by real-time quantitative polymerase chain reaction (RT-qPCR), and the cytotoxicity of the new combination on MC3T3-E1 cell was also tested. Results showed that the antibacterial and antibiofilm activities of Met could be significantly enhanced by very low concentrations of TX-100 in both normal and high-glucose conditions, with a much lower cytotoxicity than 2% chlorhexidine (CHX). Thus, the TX-100 + Met combination may be developed as a promising and effective root canal disinfectant for patients with diabetes.Keywords:antimicrobial activity;dentinal tubules;Enterococcus faecalis;high-glucose condition;metformin;Triton X-100

Chemical absorption technology has been wildly demonstrated in industry, the absorbents have become one of the most decisive factors for the process intensification of CCS technology. In this work, two schemes about bended amine and nanofluid were adopted to develop high-performance TETA-based absorbent. A bubble reaction experimental system was established to extract key data of absorbents’ properties. An AHP model was applied by setting up characteristic matrices to determine the CO 2 capture capacities of the overall aspects. The results show that the configuration of 10 wt. %TETA + 5.0 wt. %AMP has the optimal CO 2 capture performance with the highest score of 0.763 in blended amine category. The performance of nanofluids are generally higher than the blank TETA solution, though it triggers a 0.6%–3.1% growth of Purchase cost. The AHP score increases first and then declines with the rising of nanoparticle’s mass fraction, and the highest score is given to the activator of 0.1 wt. % TiO 2 . For the configurations of nanofluids- surfactants, the citrate sodium shows a superior overall CO 2 capture performance than Triton X-100, and the reasonable mass fraction of citrate sodium is considered as 0.05 wt. % with the AHP score of 0.792.
