The reduction of Fe2O3 powder at the top layer by the volatiles from high volatile (HV) bituminous coal at the bottom layer of a multilayer powder geometry including a separating alumina layer was studied. The simultaneous effects of the alumina layer thickness, time, temperature and the weight of coal on the amount of reduction and coal devolatilization were studied by implementing a rotatable...

The role of microstructural defects (dislocation density and grain boundary areas) on the passive film properties formed cold- hot-rolled interstitial free (IF) steels is investigated in 0.1 M NaOH solution. Electron backscattered diffraction (EBSD) shows higher defect cold-rolled samples. Potentiodynamic polarization (PDP) electrochemical impedance spectroscopy (EIS) results exhibit lower barr...

Conventional anaerobic digestion is currently challenged by limited degradability and low methane production. Herein, it proposed that magnetic nanoparticles (Fe3O4-NPs) bioelectrochemical systems can be employed for the improvement of organic content degradation. In this study, effect electrode configuration was examined through application a system Fe3O4-NPs in (AD). A microbial electrolysis ...

Nanoparticles (NPs) of lead tetroxide (Pb3O4) with the spherical morphology were manufactured by reaction nitrate sodium hydroxide, while nanoparticles red iron oxide (Fe2O3) similar fabricated hydrothermal route in presence ferric chloride hexahydrate as precursor. Evaluation chemical structure, purity and Fe2O3 Pb3O4 NPs was carried out analysis via X-ray diffraction (XRD) well scanning elect...

The ability to selectively destroy cancer cells while sparing normal tissue is highly desirable during the cancer therapy. Here, magnetic targeted photothermal therapy was demonstrated by the integration of MoS2 (MS) flakes and Fe3O4 (IO) nanoparticles (NPs), where MoS2 converted near-infrared (NIR) light into heat and Fe3O4 NPs served as target moiety directed by external magnetic field to tum...

Coal ash is one of the significant factors for operating efficiency pressurized coal chemical looping gasification (CLG). To explore influence mechanism physical deposition and combination on iron-based oxygen carrier (OC) under conditions, effects content, components pressure reduction performance Fe2O3/Al2O3 OC are investigated. The micro-structure phase transformation particles conditions ch...

Weathering products of two fragments of Dronino iron ungrouped meteorite found in the wet and drier clay sand were studied using X-ray diffraction and Mössbauer spectroscopy with a high velocity resolution. The products of metal oxidation in the internal and external surface layers were different for both fragments. The weathering products in fragment found in the wet clay sand contain magnetit...

Background Pathogenic bacteria have always been a significant threat to human health. The detection of pathogens needs to be rapid, accurate, and convenient. Methods We present a sensitive surface-enhanced Raman scattering (SERS) biosensor based on the combination of vancomycin-modified Ag-coated magnetic nanoparticles (Fe3O4@Ag-Van MNPs) and Au@Ag nanoparticles (NPs) that can effectively cap...
