    Synthesizing Iron Atom Doped Carbon Nanotubes by Elguja R Kutelia, Ayten S Bakhtiyarova, Sayavur I Bakhtiyarov

    Published 2025-01-01
    “…Iron nanoparticles tend to agglomerate due to their strong magnetic interactions and high surface energy, resulting in inhomogeneous doping that diminishes the effectiveness of the composite in applications like electromagnetic shielding, catalysis, or energy storage. To mitigate this, controlled synthesis techniques such as Chemical Vapor Deposition (CVD) with regulated precursor flow rates or solution-based methods with surfactants can be utilized. …”

    From density functional theory to machine learning predictive models for electrical properties of spinel oxides by Yuval Elbaz, Maytal Caspary Toroker

    Published 2024-05-01
    “…Abstract This work focuses on predicting and characterizing the electronic conductivity of spinel oxides, which are promising materials for energy storage devices and for the oxygen evolution and oxygen reduction reactions due to their attractive properties and abundance of transition metals that can act as active sites for catalysis. To this end, a new database was developed from first principles, including band structure and conductivity properties of spinel oxides, and machine learning algorithms were trained on this database to predict electronic conductivity and band gaps based solely on the compositions. …”

    Assessment of the Oxidative Desulfurization of Middle Distillate Surrogate Fuels with Spectroscopic Techniques by Eleni Syntyhaki, Anastasia Detsi, Dimitrios Karonis

    Published 2020-01-01
    “…The goal of this study was the implementation of a simple and economical oxidative and extractive system for the desulfurization of surrogate mixtures with an intermediate sulfur concentration 1% w/w, at the mild temperature of 70°C, and without the use of supplementary and assisting methods such as heterogeneous catalysis or ultrasound irradiation. The sulfur content was estimated using X-ray fluorescence. …”
