In this study, we report the development of an EDTA-crosslinked cyclodextrin polymer (ECDP)-based sensor for the real-time, naked-eye detection of hazardous methylene blue (MB) dye in aqueous solutions and natural water samples. The sensor functions via a competitive host–guest inclusion mechanism involving sodium dodecyl sulphate (SDS) and ECDP, which modulates the alignment of liquid crystals (LCs). Initially, SDS induces homeotropic ordering at the fluid interface, but when complexed with ECDP, it causes a tilted LC alignment. Upon the introduction of MB, SDS is displaced from the ECDP cavity and re-adsorbs at the LC/aqueous interface, triggering an orientational transition from tilted to homeotropic. This transition is clearly observed as a distinct bright-to-dark shift under crossed polarizers. The host–guest (ECDP/MB) inclusion complexation mechanism was further confirmed by FT-IR, XRPD, and DSC analyses. The developed sensor exhibits high selectivity for MB in dye-contaminated natural water samples and sensitivity to MB concentrations upto 0.10 mM. This study demonstrates the potential of cyclodextrin-based polymers for liquid crystal sensing applications, offering promising pathways for future developments in environmental monitoring.</div></div>","PeriodicalId":371,"journal":{"name":"Journal of Molecular Liquids","volume":"416 ","pages":"Article 126479"},"PeriodicalIF":5.3,"publicationDate":"2024-11-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142655189","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study presents a green, eco-friendly approach to imparting antimicrobial properties to cellulose cotton fabric (CCF) by depositing silver nanoparticles (AgNPs) synthesized using <em>Bryophyllum pinnatum</em> (BP) leaf extract as a natural reducing agent. To improve the durability of AgNPs on CCF, an environmentally friendly method was used to synthesize AgNPs, which were subsequently applied to biocompatible CCF using BP leaf extract as a natural reducing agent. Owing to the presence of phytochemicals, the AgNPs were rapidly produced with a uniform size and shape under ambient conditions. The synthesized nanoparticles were characterized using techniques such as ultraviolet–visible spectroscopy, Fourier-transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM) coupled with energy dispersive X-ray (EDX) spectrophotometry, and X-ray diffraction (XRD) analysis to confirm their size (average size 60.4 ± 8.5 nm), morphology, and crystalline structure. Subsequently, the CCF was coated with these AgNPs using an eco-friendly deposition method. The mechanical properties of the treated fabric were assessed to ensure that the coating process did not compromise the fabric’s integrity or safety for human use. The results indicated that the CCF–BP–AgNPs retained its mechanical strength and exhibited no cytotoxic effects, regarding it suitable for various applications in healthcare, apparel, and household textiles. The antibacterial activity of the CCF–BP–AgNPs was evaluated by measuring zone inhibition against <em>Escherichia coli</em>, <em>Bacillus subtilis</em>, and <em>Staphylococcus aureus</em>. The photocatalytic activity of the coated cloth was assessed by observing the breakdown of organic dye Congo Red (CR) in simulated sunlight.

Hence, this study deals with the development of comprehensive models for estimating the <em>C_p</em> of DESs. To reach this target, 682 experimental data, encompassing the <em>C_p</em> of 36 different DESs over widespread ranges of pressure and temperature, were assembled from the literature. The foregoing data were employed to establish new models based on four machine learning techniques, including Gaussian process method (GPM), Adaptive neuro-fuzzy inference system (ANFIS), Radial basis function neural network (RBF-NN) and Multilayer perceptron neural network (MLP-NN). The evaluations performed based on the statistical indices and graphical tools demonstrated that although all suggested models present excellent estimations, that designed based on the MLP-NN method yields the highest accuracy with Mean absolute percentage error (MAPE) and coefficient of determination (<em>R²</em>) values being 0.4% and 99.93, respectively, for the validation data. A comparison between the results of the literature correlations and those of novel models confirmed the obvious superiority of the latter. Moreover, the proposed models properly described the <em>C_p</em> variations of different DESs versus pressure and temperature. The order of importance of various factors in controlling the <em>C_p</em> of DESs was also determined based on the sensitivity analysis.

Previous studies have focused on the depression of galena. In this study, gallic acid (GA) was utilized as a molybdenite depressant during Mo-Pb flotation separation. Single mineral flotation experiments showed that pH notably influenced galena and molybdenite flotation with GA, particularly at pH 10, displaying the most substantial recovery difference. Mixed mineral flotation experiments revealed GA’s selective depression on molybdenite. At the optimal dosage of GA, the Mo recovery was reduced by 76.62 percentage points, while the Pb recovery remained unaffected. The depression and separation mechanisms of GA were investigated using contact angle, infrared spectroscopy, Zeta potential, inductively coupled plasma optical emission spectrometer (ICP-OES), X-ray photoelectron spectroscopy (XPS) analysis, first-principles calculations analysis, and interface interaction free energy calculations. The results indicate that GA treatment significantly reduces the hydrophobicity of molybdenite surfaces; however, it slightly enhances the hydrophobicity of galena surfaces. At pH 10, the primary species in GA solution is HGA^3-. It adsorbs on PbO species of the galena surface as Pb-GA complexes and tends to detach from the surface at high adsorption capacity, resulting in galena not being depressed by GA. Differently, GA adsorbs on the molybdenite surface through hydrophobic attraction force, rendering it hydrophilic. Additionally, after treatment with potassium butyl xanthate (PBX), the hydrophobicity of GA-treated galena is significantly enhanced, while the hydrophobicity of GA-treated molybdenite is not restored. This is because PBX can adsorb stably on GA-treated galena, but its adsorption on GA-treated molybdenite is hindered by the pre-adsorbed GA.</div></div>","PeriodicalId":371,"journal":{"name":"Journal of Molecular Liquids","volume":"416 ","pages":"Article 126460"},"PeriodicalIF":5.3,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142655157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
