TiO2-based strategies for mitigating hexavalent chromium in portland cement: a mechanism-guided mini review

Frontiers in Materials
Hexavalent chromium, Cr(VI), remains a critical concern in cement and clinker-based materials because of its solubility, mobility, and health-related risks.

Sensitivity Analysis of CO₂ Emitted in Clinker and Cement Production

Computation
This study performs a sensitivity analysis of CO2 emissions from clinker and cement production using life cycle assessment (LCA). Both local and global sensitivity analyses (LSA and GSA) are conducted. LSA uses outputs from the GCCA EPD tool—developed by

Determination of Slurry’s Properties of Oil Well Cement Produced from Local Raw Materials

UMYU Scientifica Journal
Oil well cementing is a critical step in well construction, where cement slurry is pumped into the annular space between the casing and the borehole wall to achieve zonal isolation, provide casing support, and ensure long-term well stability.

Coal Fires as Geomorphic Agents in Northwestern China: Evidence from Combustion Metamorphic Rocks and Associated Landforms

Fire
Natural coal fires are commonly investigated as sources of resource loss and environmental disturbance, yet their capacity to shape relief after combustion remains poorly resolved. This study examines the geomorphic expression of natural paleo-coal fires
