In this study, the synthesis of a new Hg²⁺ chemosensor-based nanomagnetic particle (Fe₃O₄@SiO₂@Pr-NCIM) was investigated via coating the Fe₃O₄ magnetic nanoparticles (MNPs) with SiO₂, 3-Aminopropyltriethoxysilan (APTES), and Imidazole-2-Carbaldehyde, resp., and then it was characterized through the different analyses, including FT-IR, SEM, EDX, and VSM.The fluorescence properties of the Fe₃O₄@SiO₂@Pr-NCIM were studied in the presence of various cations in EtOH as a green solvent.The obtained results showed that it can be utilized as a new chemosensor with high sensitivity and selectivity for Hg²⁺ ion.In addition, the impressive limit of detection (LOD) of 4.03 x 10^-6 for the Hg²⁺ ion demonstrated the acceptable linear relation between Hg²⁺ concentration and the fluorescence intensity of the synthesized Fe₃O₄@SiO₂@Pr-NCIM structure.Utilizing the B3LYP/6-311g (d,p)/LANL2DZ method, DFT calculations were conducted, encompassing MEP map, geometry optimization, HOMO-LUMO, and the evaluation of quantum descriptors.The exptl. mechanism of interaction between the ligand and Hg²⁺ is confirmed by the DFT calculation

A risk-based maintenance planning in process industry using a bi-objective robust optimization model

Author: Monfared, Mohammadali Saniee ; Alipour, Zohreh ; Monabbati, Sayyed Ehsan

We have developed an innovative risk-based maintenance planning methodol. using a bi-objective scenario-based robust optimization model.This approach determines robust, optimal maintenance intervals for process industries.Our methodol. comprises two main phases: risk assessment and maintenance planning.In the initial phase, we identified critical items using a Bow-tie diagram, which is subsequently mapped into a Bayesian network to estimate the overall risk based on historical data and process knowledge.In the second phase, we developed a bi-objective scenario-based robust optimization model to Pareto-optimize both risk and cost under operational risks.This results in a robust maintenance plan capable of withstanding time, costs, and failure rate uncertainties inherent in process industries with considering decision-makers′ attitudes to risk (risk-averse, risk-neutral, or hybrid attitude).The computational results demonstrate the significant impact of considering uncertainty of critical data, and robustness on the selected maintenance plan and system performance.

Functionalizing UiO-66-NH2 by 4‑chloro-3-formylcoumarin, as an optical chemosensor of Al3+ and F− and its computational studies

Author: Feizi-Dehnayebi, Mehran ; Mirhosseyni, Marziesadat ; Badiei, Alireza ; Mohammadi Ziarani, Ghodsi ; Moradi-Chaleshtori, Fateme

Metal-organic frameworks (MOFs) have arisen as a promising category of substances for sensing applications because of their unique structural features and tailorable characteristics.In this study, functionalization of UiO-66-NH₂ with 4-chloro-3-formylcoumarin was completed to enhance the fluorescence properties and selective binding interactions.So, the florescence response of UiO-66-N-ChloroCoumarin (UiO-66-N-CC) towards various ions was studied and the obtained results represented high selectivity for Al³⁺ and F^- ions in EtOH.The UiO-66-N-CC exhibited a linear correlation for Al³⁺ ions from 10 to 940 μL, with detection limit of 8.79 x 10^-5 M and for F^- ions, from 10 to 100 μL, with detection limit of 3.39 x 10^-5 M.Addnl., the influence of potential interfering ions, including Ag⁺, K⁺, Pb²⁺, Hg²⁺, Cd²⁺, Ni²⁺, Ca²⁺, Cu²⁺, Mg²⁺, Mn²⁺, Co²⁺, Zn²⁺, Cr³⁺ for Al³⁺ and Br^-, Cl^-, I^-, F^-, CN^-, SCN^-, OH^-, NO^-₂, CH₃COO^-, HSO^-₃, SO^2-₄, Cr₂O^2-₇, HPO^2-₄, CO^2-₃ for F^-, was investigated, demonstrating minimal effects on the fluorescence emission, conforming the selectivity of the method.The gaseous phase d. functional theory (DFT) calculation was performed by B3LYP/6-311 g (d,p)/def2-TZVP computational methodol. for the ground state of UiO-66-N-CC and UiO-66-N-CC+Al³⁺complex.The reactivity, stability, and mechanism of the interaction between UiO-66-N-CC and Al³⁺ ions were investigated by DFT calculations like geometry optimization, MEP surface, and MO theory.
