Double Slag Operating Standard for Mitigation of CO2 Emissions in Basic Oxygen Steelmaking

steel research international, EarlyView.
Basic oxygen furnace (BOF) steelmaking uses a double slag process (DSP) to produce low‐phosphorus steel. To reduce carbon emissions in a BOF, the hot metal ratio (HMR) must be lowered. The present article describes the optimal conditions for DSP operations under low‐HMR conditions: temperature of 1360 ± 5 °C, total Fe content of 10 ± 2 wt%, basicity (=

Sequential Reduction of Chromite Pellets Using Hydrogen and Silicon Carbide for Carbon Emission Abatement During Ferrochrome Production

steel research international, EarlyView.
H2 prereduction selectively metallizes Fe in UG2 chromite pellets at 1100°C, while silicon carbide becomes active at 1300°C to convert remaining Cr2O3 to carbides and promote Cr metallization. By separating the roles of H2 and SiC, the sequential route reaches up to 65.7% Cr metallization and suppresses in‐furnace CO generation by ≈75% versus ...

Elucidation of Degradation Mechanism, Kinetic Triplets and Product Analysis of Nafion N115 Membrane: An Experimental and Theoretical Study

Safety Science and Technology, EarlyView.
Thermal degradation mechanism and kinetic triplets of Nafion N115 were elucidated via TGA, kinetic compensation analysis, Sestak–Berggren reconstruction, quantum calculations, and GC–MS. A diffusion‐controlled model governs active pyrolysis, although persistent perfluorinated products were identified, highlighting environmental implications and ...

Protic Ionic Liquids in Contrast to Aprotic Analogs: Transport Properties and Electrochemical Reactivity

The Chemical Record, EarlyView.
The transport properties and electrochemical reactivity of protic ionic liquids (ILs) are compared with those of aprotic analogs. Protic ILs are characterized by strong cation–anion hydrogen bonding and labile protons, enabling proton conduction and highlighting their potential as fuel cell electrolytes.

Iron Physiology and Its Impact on Atopic Diseases: An EAACI Taskforce Report

Allergy, EarlyView.
ABSTRACT Iron is essential for oxygen transport, energy metabolism, and immune regulation. Yet iron deficiency is the most common micronutrient disorder across all age groups, affecting nearly one quarter of the global population. Iron deficiency triggers nutritional immunity, a host defense mechanism that withholds and redistributes iron, contributing
