Lead (Pb) is a heavy metal known for its adverse effects on both human health and the environment. In recent years, the industrial utilization of Pb²⁺ has surged, underscoring the imperative need for efficient measurement methods. In this study, a rapid and simple photochemical method was used to synthesize thioglycolic acid (TGA)-stabilized CdTe/ZnSe core-shell quantum dots (QDs). These CdTe/ZnSe QDs emit vibrant green fluorescence and exhibit remarkable quenching in the presence of Pb²⁺ ions. This property enables the development of an on-site on/off sensor without the necessity of additional modifications. The proposed sensor possesses an outstanding sensitivity to Pb²⁺, with a detection limit and linear range of 31.8 nM and 50 nM-10 µM, respectively. Importantly, the selectivity of this fluorescence-based sensor was validated by analyzing various positively and negatively charged ions. Furthermore, the developed sensor showed reliable performance against real river, agricultural, and tap water, as confirmed by Inductively Coupled Plasma (ICP) analysis. Additionally, CdTe/ZnSe QDs immobilized on glass slides were successfully employed for on-site water sample analysis, providing a versatile solution for environmental monitoring.

Herein, the synthesis of multifunctional engineered GOs with the structure of GO@Fe₃O₄-ligands-CdTe quantum dots (QDs) by an environment-friendly aqueous method was reported. l-cystein (Cys), 3-trimethoxysilyl-propanethiol (TMSP), and glutathione (GSH) were selected as ligands.The as-prepared GO@Fe₃O₄-ligands-CdTe QDs hybrid nanostructures were characterized by different methods.The findings indicate that the nanocomposites of GO@Fe₃O₄-ligands-CdTe QDs demonstrate superparamagnetic properties at room temperatureThe saturation magnetization values for GO@Fe₃O₄, GO@Fe₃O₄-Cys-CdTe, GO@Fe₃O₄-GSH-CdTe, and GO@Fe₃O₄-TMSP-CdTe, are 25, 14, 16, and 2 emu g^-1, resp.These nanocomposites show stable and strong luminescence at 580-600 nm.The magnetic nanostructures also reveal the absorption wavelength at 300-490 nm.Using TMSP ligand as a bridge between QDs and magnetic GOs, the luminescence of the nanostructure has not decreased much compared to CdTe QDs.The use of Cys ligand preserves the saturation magnetism of the nanocomposite more than magnetic GO, and the dispersed nanostructure is stable in water.Furthermore, the transverse and longitudinal optical (TO and LO) phonon modes of prepared GO@Fe₃O₄-ligands-CdTe QDs were obtained by Kramers-Kronig (KK) relations based on fourier-transform IR (FTIR) spectroscopy.The Z-scan results show that the type of used ligand has a great effect on the nonlinear optical (NLO) properties of the final product.The largest NLO parameters are related to GO@Fe₃O₄- TMSP -CdTe QDs, and the values of nonlinear absorption coefficient and nonlinear refractive index were obtained as 2.17 x 10^-3(cm/W) and10.27 x 10^-8(cm²/W), resp.As a result, GO@Fe₃O₄-ligands-CdTe QDs nanostructures can be considered as promising multifunctional nanostructures for various biomedical applications and NLO devices.

A modified method for detection of interface and onset point in the asphaltenic fluids

作者: Barzegar, Farzad ; Shahparast, Mehdi Bayat ; Shabani, Ali

Asphaltene precipitation and deposition causes many serious problems to the petroleum industry from the reservoir to the surface facilities.Therefore, it is important to bring it under control by finding a method to accelerate or slow down its precipitation and deposition.For achieving this purpose two parameters play an important role; onset point of the precipitation and amount of the deposited phase.When asphaltene precipitates, it is capable of depositing in the solutionAfter the deposition, the solution split into two phases; asphaltene-rich and asphaltene-lean.Determining the amount of the deposited phase needs to distinguish the interface between two phases.In this study, a novel method has been developed for simultaneous detection of the onset point and the interface using a single IR beam at the standard pressure and temperatureThe proposed method is based on the IR light absorption and scattering during precipitation and deposition of the asphaltene aggregates.The results of the paper show that the proposed method can properly measure the interface of the deposited phase (error <6%).Also, the measured onset point of the precipitation for the asphaltenic solution is in the acceptable range (0.4-0.5 volume fraction).
