Hybrid carbon-based materials are in demand to achieve the desired activities in various fields. However, such materials lack aqueous dispersibility or mechanical strength, which can be addressed by certain modifiers such as surfactants, polymers, metal oxides, and deep eutectic solvents (DESs), among others. Dodecyl trimethylammonium bromide (DTAB) and a typical DES (reline; choline chloride/urea, 1:2) have been employed in conjunction with graphene oxide−titanium oxide nanocomposites (GO@TiO 2 NCs) to get advanced adsorbents (which are characterized by various physicochemical techniques). A model hazardous dye, methylene blue (MB), was used to study the adsorption potential of the above-developed material. The process was optimized in terms of the adsorbent dose, initial MB concentration, pH, and contact time. Various kinetic and adsorption isotherm models were used to analyze the data. Pseudosecond-order kinetics (R 2 = 0.999) has been followed by the Langmuir adsorption isotherm (R 2 = 0.998). Kinetics revealed that 100% MB adsorption was achieved with DES-based NC (DES-GO@TiO 2 ), which is better than that with both DTAB-based (DT-GO@TiO 2 ) and pure pristine material (GO@TiO 2 ). It is proposed that DES (reline) couples TiO 2 on the GO surface with an alternative route to drive MB from an aqueous background. Adsorption data were compared with other similar reported adsorbents, and it was found that the developed DES-based advanced material shows ultrafast MB adsorption (the rate of adsorption has been found to be 222 μg MB per gram of DES-GO@TiO 2 in 1 s). The sustainability and economy of the adsorbent were revealed by repeating numerous adsorption cycles (up to seven times) without losing the adsorption efficiency. The study can be applied in various chemical industries where color or coloring material is involved in the effluent. Further, other similar greener DESs should be used in order to develop sustainable structure−performance relationship for a safer environment.

“…In recent years, a broad community of surface chemists has shown a great deal of scientific interest in the physicochemical modifications of surface-active agents in an attempt to improve the functionality of surfactant formulations. In this context, various additives, including salts, solvents, polymers, drugs, etc., have been introduced to the micellar environment of amphiphilic systems to achieve the desired features with various industrial importance in cosmetics, food products, enhanced oil recovery, and pharmaceuticals . Among all the additives, nonaqueous alcohol solvents have been examined mostly in amphiphile-water-solvent ternary systems using both theoretical and experimental approaches. − The exceptional solubilizing and hydrogen bonding potential of alcohols distinguish them as solvents of choice .…”

The influence of 2,2,2-trifluoroethanol (TFE) on the micellar properties of ionic surfactants hexadecyltrimethylammonium bromide (CTAB), hexadecyltrimethylammonium ptoluenesulfonate (CTAT), sodium dodecyl sulfate (SDS), Nlauroylsarcosine sodium salt (SDDS), and nonionic surfactant Triton X-114 (TX-114) in aqueous solutions was studied using tensiometry, electrical conductivity, fluorimetry, time-resolved fluorescence, and microcalorimetry. With increasing concentrations of TFE, the micellar charge densities of the ionic head groups decrease, causing a decrease in the critical micelle concentration (CMC) of ionic-surfactant solutions (SDS, SDDS, CTAB, and CTAT) in micellar solutions. However, for nonionic surfactant TX-114, the polar headgroup undergoes some conformational changes causing an increase in the value of CMC. Time-resolved fluorescence decay measurements were done to get evidence of penetration of TFE molecules into the stern layer of the micelle. The micellar aggregation number declines with increasing concentration of solvent, indicating a higher concentration of mixed solvent reducing the number of monomers needed for micellization for ionic surfactants, whereas for nonionic TX-114, it indicates some structural changes of the molecule forming the micelle in the presence of TFE.

“…One of them is using Gemini amphiphilic aggregates in gene delivery [10,11], antimicrobial activity [12,13], and sooner or later the synthesis of mesoporus material [14,15]. Another issue of those traits is the creation and observe of several cationic Gemini surfactant categories [16][17][18][19][20].…”

On the basis of alkyl alcohol and eipchlorohydrine three novel multi-alkyl quaternary-ammonium salt cationic surfactants have been created. 1H-NMR and FTIR spectrometry researches are used on this investigation. Artificial products structures are confirmed by FTIR and 1H-NMR spectrometries. There is an increase in alkyl group in the order C4 < C6 < C8. This growth is used to pick out the decline in critical micelle concentration (CMC), which discovered that the higher the floor features, the bigger the alkyl group. MTT cytotoxicity assay is used to assess the organic efficacy of Gemini surfactants as well as estimating their toxicity. Compound A3 was discovered to has a high impact on MCF-breast most cancers cell line. It reached the best rate of inhibition of 27.28% - 5.4% with concentration 25 – 400 µg ml-1, in comparison with compounds A1 and A2. The rate of inhibition for A1 is 36.3% - 5.3% with concentration 25 – 400 µg ml-1. The rate of inhibition for A2 is 48.9% - 5.6 % with concentration 25 – 400 µg ml-1.
