Expanding effective, affordable, and versatile electrocatalysts for water splitting to produce hydrogen fuel is a significant challenge.Herein, a composite based on iron (III) oxide @ N- doped carbon (NC) - reduced graphene oxide (Fe₃O₄@NC/RGO) was prepared using simultaneous pyrolyzing an aspartic acid/iron-based MOF and graphene oxide (Asp-Fe MOF/GO) nanocomposite.The synthesized Fe₃O₄@NC/RGO features a large active surface area and a well-dispersed arrangement of active sites, resulting in exceptional multifunctional properties for hydrogen and oxygen evolution reactions (HER and OER).It exhibits low overpotentials of 295 mV for OER and 105 mV for HER at a c.d. of 10 mA cm^-2 in 1 M KOH.The results indicate that the multifunctional properties of Fe₃O₄@NC/RGO, characterized by an abundance of active sites, excellent elec. conductivity, and an optimal electronic structure, are attributed to the synergistic effects of iron oxide, N-doped carbon, and reduced graphene oxide (RGO).This synergy enhances the electrocatalytic properties of the composites.The multifunctional qualities of the Fe₃O₄@NC/RGO composite make it highly desirable for various sustainable and renewable energy-related applications.

Domino-like turn-on chemiluminescence amplification: Opening a gateway through proximal-imidazole species formation and metal-ligand complexation

Article

Due to their extremely low background signal and high sensitivity, the chemiluminescence (CL) probes have received a great attention in various chemical and biological applications. However, the lack of selectivity is still a challenging task. As an innovative topic of research, in this work we developed a domino-like turn-on CL reaction through proximal-imidazole species for the first time. The oxidation reaction of N-(2H-[1,2,4]thiadiazolo[2,3-a]pyridine-2-ylidene)benzamide (1) by hydrogen peroxide found to promoted by a domino-like reaction between proximal imidazole species and the Co²⁺-1 complex formation which accompanied by a dramatically turn-on emission. In the way of explaining the possible mechanism, the application of density functional theory (DFT) studies revealed that there are three possible pathways for the reactions between precursor 1 and HOO^- in the presence of imidazole to produce the oxidized isomers. The strongest interaction found to occur in pathway 3, in which the sulfur atom was oxidized, while there was some repulsion between HOO^- and 1, due to the effects of two different charges in pathways 1 and 2. To confirm tits applicability, the CL system was successfully applied to highly selective quantification of vitamin B₁₂ in some real samples. The linear dynamic range was achieved from 0.08 to 34 ng mL^-1 and the detection limit was evaluated as 0.028 ng mL^-1. This new method introduced fluorescence selectivity and CL sensitivity in single technique. It was finally anticipated that the CL amplification through proximal-imidazole species possesses a great potential on tuning various color-emissions based on different metal-ligand complex formations studied.

Identification and classification of adulteration in some fossil fuel products using an electronic nose

作者: Kakaei, Amir ; Naderloo, Leila ; Mostafaei, Mostafa

The objective of this study was to identify and classify adulteration in certain fossil fuel products (including gasoline, diesel, and kerosene) using an electronic nose (e-nose).In this research, blends of gasoline-diesel, gasoline-kerosene, and diesel-kerosene were prepared at volumetric ratios of 5%, 10%, 15%, 20%, 25%, and 30%.Data acquisition was performed using an e-nose system equipped with 10 metal oxide semiconductor (MOS) sensors.The collected data were analyzed using various methods, including Linear Discriminant Anal. (LDA), Quadratic Discriminant Anal. (QDA), Support Vector Machine (SVM), and Artificial Neural Network (ANN).Among the sensors, MQ135, TGS2611, and TGS2610 demonstrated the highest performance.The results showed that the identification and classification of pure fuels using QDA, SVM, and ANN achieved 100% accuracy, while the LDA method achieved 98.8% accuracy in distinguishing pure fuel types.Based on the results, the e-nose system demonstrated over 90% accuracy in detecting and classifying fuel adulteration, outperforming traditional methods based on conductivity and pH measurements.
