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 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 ... -
Iron oxide@graphitic carbon core-shell nanoparticles embedded in ordered mesoporous N-doped carbon matrix as an efficient cathode catalyst for PEMFC
(2020)Developing electrocatalysts with high activity and long-term stability towards oxygen reduction reaction (ORR) in acidic media is still an important topic. However, most of the already reported non-precious-metal catalysts ... -
Micromixing efficiency of particles in heavy metal removal processes under various inlet conditions
(2019)Water quality problems are a persistent global issue since population growth has continually stressed hydrological resources. Heavy metals released into the environment from plating plants, mining, and alloy manufacturing ... -
On the magnetic aggregation of Fe3O4 nanoparticles
(2021)Background and objective In-vivo MRI-guided drug delivery concept is a personalized technique towards cancer treatment. A major bottleneck of this method, is the weak magnetic response of nanoparticles. A crucial improvement ... -
Remediation of Polluted with Chromium Waters and Soils Cultivated with Wheat (Triticum durum) Using Zeolites Modified with Iron Oxide
(2016)The present study examines the efficiency of soil amendments regarding the retention of chromate ions, from water and cultivated soil with wheat (Triticum durum). The minerals and iron oxides that have been used were ... -
Soil and maize contamination by trace elements and associated health risk assessment in the industrial area of Volos, Greece
(2019)Agricultural lands adjacent to industrial activities are vulnerable due to the risk of trace elements (TEs) being accumulated into crops and subsequently humans. One such case concerns the industrial area of Volos, Greece, ...
