Increasing Contribution of Condensable Particulate Matter From Stationary Combustion Sources Under Strict Control Standards in China

Geophysical Research Letters, Volume 52, Issue 17, 16 September 2025.
Abstract China's implementation of stringent emission control measures during 2014–2020 has effectively reduced filterable particulate matter (FPM) emissions from stationary combustion sources, while increasing the contribution of condensable particulate matter (CPM) to total PM emissions.

Effect of Coordination Structure of Iron Ions on Iron Oxide Activity Coefficients in the CaO‐SiO2‐FeO‐Fe2O3 Slags at 1573 K Under Oxygen Partial Pressures Between 10−9 and 10−4 atm

steel research international, Volume 96, Issue 8, August 2025.
Activity coefficients of FeO and FeO1.5 in CaO‐SiO2‐FeO‐Fe2O3 melts have been investigated from the perspective of the coordination structures of iron ions. γFeO are higher than γFeO1.5$$ \gamma_{\text{FeO}_{1.5}} $$. In addition, γFeO1.5$$ \gamma_{\text{FeO}_{1.5}} $$ increases with increasing the ratio of Fe3+(oct) pct./Fe3+(tetr) pct., which ...

Thermodynamic Constraints and Prospects for Intensified Steel Deoxidation

steel research international, Volume 96, Issue 8, August 2025.
The article provides a short survey of steel deoxidation and considers how to increase its efficacy. Bringing a specially tailored, powdered slag into the reaction site can directly bind the deoxidation product oxides, resulting in lower dissolved oxygen activity, total oxygen content, and cleaner steel.

Electrified Carbon Cycling for Neutralizing the Steelmaking Industry

Carbon Energy, Volume 7, Issue 7, July 2025.
Steelmaking is energy‐intensive and heavily reliant on fossil fuels, contributing significantly to global carbon emissions. Developing a renewable processing approach compatible with existing infrastructure is urgent. Electrified carbon cycling based on CO2RR converts CO2 into CO, reducing coke usage and CO2 emissions, thus enabling carbon‐neutral ...
