Computational analysis of paramagnetic spherical Fe3O4 nanoparticles under permanent magnetic fields
(2018)The influence of permanent constant magnetic fields on the paramagnetic nanoparticles motion is analyzed in this study. The numerical model is developed in the OpenFOAM® platform and includes all major forces acting on ... -
Enhanced electrocatalytic overall water splitting over novel one-pot synthesized Ru–MoO3-x and Fe3O4–NiFe layered double hydroxide on Ni foam
(2021)Herein, two novel electrocatalysts are simultaneously grown on Ni foam (NF) through a one-step hydrothermal method. The as-prepared Ru–MoO3-x NF exhibits good performance for HER with low overpotentials of 12 mV at 10 mA ... -
Enhanced Ultrasonic-Assisted Heterogeneous Fenton Degradation of Organic Pollutants over a New Copper Magnetite (Cu-Fe3O4/Cu/C) Nanohybrid Catalyst
(2020)A copper magnetite nanohybrid catalyst (Cu-Fe3O4/Cu/C), abundant of Schottky interfaces and structural defects, with ultrathin encapsulation of graphitic carbon, was synthesized and tested. The catalyst shows enhanced ... -
Magnetic nanoparticles in medical diagnostic applications: Synthesis, characterization and proteins conjugation
(2016)Background: Magnetic nanoparticles (NPs) used in biomedical applications should be discrete with small particle sizes, narrow size distribution and superparamagnetic. NPs can be tailored to target, through chemical bonds, ... -
Mixing of Fe3O4 nanoparticles under electromagnetic and shear conditions for wastewater treatment applications
(2022)The ability of heavy metals to accumulate in living organisms, combined with the fact that they are not biodegradable, necessitates an expansion and improvement of the existing water purification methods. An effective ... -
Novel Fe7S8/C nanocomposites with accelerating iron cycle for enhanced heterogeneous electro-Fenton degradation of dyes
(2022)Fe3+/Fe2+ interconversion is one of the key factors for heterogeneous electro-Fenton degradation of organic pollutants. In this study, MIL-101Fe-derived carbon wrapping Fe7S8 nanocomposite (Fe7S8/C-1-600) exhibits outstanding ... -
