·The oxide scale is predominantly two layered with an outer layer of magnetite and an inner layer of wüstite The wüstite layer takes up about 2/3 of the oxide layer in thickness After the oxide scales were peeled off from high carbon steel the exterior and opposite surfaces were observed
Steel production causes a third of all industrial CO2 emissions due to the use of carbon based substances as reductants for iron ores making it a key driver of global warming Therefore research efforts aim to replace these reductants with sustainably produced hydrogen Hydrogen based direct reduction HyDR is an attractive processing technology given that direct
·We studied the kinetics of the formation of iron oxide nanocrystals obtained from the solution phase thermal decomposition of iron−oleate complex via the heating up process To obtain detailed information on the thermal decomposition process and the formation of iron oxide nanocrystals in the solution we performed a thermogravimetric mass spectrometric analysis

·Iron oxide scale is a by product of continuous casting billet or steel ingot and its rolling process also known as iron scale which accounts for about % of annual steel production [] For example global crude steel production in 2021 was billion tons and the output of iron oxide scale was about million tons which is quite considerable []
·Furthermore lesser amounts of regular iron oxides can present above the dense Cr 2 O 3 layer due to lower solubility of oxygen and diffusivity of ions [6] Therefore the existence of the columnar coarse grained magnetite middle layer is unlikely in oxide scales of alloys containing Cr concentration above the critical quantity
·Sustainable iron production methods such as electrolysis of iron chloride or oxide and deep eutectic solvent extraction are investigated to reduce the carbon footprint in the iron and steel industry is a promising technology that has already been demonstrated on a small scale 135 In this process the electrolyte is iron ore iron oxide
·Co precipitation synthesis of stable iron oxide nanoparticles with NaOH New insights and continuous production via flow chemistry Furthermore thermal decomposition syntheses require post processing steps such as purification and phase transfer usually after a time consuming ligand exchange step if IONPs need to be dispersed in aqueous
A similar concept can be used to investigate the effect of Ni incorporation into cobalt oxide spinel and to optimize the electrocatalyst composition 29a As shown in Figure 8 e f Ni containing cobalt oxide samples show different OER activities after an activation process due to the uptake of iron impurities from KOH electrolytes
·1 Introduction Methane CH 4 is a powerful greenhouse gas in the Earth s atmosphere generating 28 34 times more radiative forcing than carbon dioxide CO 2 on a centennial time scale Myhre et al 2013 A major part of the CH 4 on Earth is produced in marine sediments by methanogenesis which is the final step in the gradual fermentation of organic
