Bridging the Late Antique Gap in Northwest Arabia: New Archaeological Evidence on the Occupation of Wādī al‐Qurā (al‐ʿUlā [AlUla], Saudi Arabia) Between the Third and Seventh Centuries CE

Arabian Archaeology and Epigraphy, EarlyView.
ABSTRACT In 2019, the Dadan Archaeological Project (CNRS/RCU/AFALULA) identified a Late Antique village 1 km south of ancient Dadan in the al‐ʿUlā valley (northwest Saudi Arabia). Three excavation seasons at this site (2021–2023) have uncovered a massive building constructed in the late third or early fourth cent.

Review of recent advances in the design, synthesis, and modification of biochar for remediation of heavy metal pollution in water

The Canadian Journal of Chemical Engineering, Volume 104, Issue 4, Page 1769-1795, April 2026.
Research frontiers in using biochar for heavy metal remediation. Abstract Heavy metal contamination of water has long been a serious environmental issue. Biochar and biochar‐based composites are emerging as effective and sustainable solutions for heavy metal removal due to their strong adsorption abilities and environmentally friendly nature.

Modeling of Physical–Chemical and Thermomechanical Properties of Glasses From Recycled Waste

International Journal of Applied Glass Science, Volume 17, Issue 2, April 2026.
ABSTRACT This research focuses on understanding the high‐temperature phase evolution occurring during the vitrification of heterogeneous construction and demolition wastes (CDWs). The aim of this project is to transform this widely distributed and mostly unused waste stream into a homogeneous, engineered, glass‐based material with predictable ...

Unlocking Green Oxygen's Potential for Planetary Carbon Management

ChemSusChem, Volume 19, Issue 5, 13 March 2026.
Water electrolysis generates both H2 and O2, yet industrial focus remains largely restricted to H2‐driven reductions. The parallel use of O2 offers considerable rewards but remains underexplored. Unlocking this dual‐gas potential necessitates robust cross‐sector communication to identify and scale viable industrial use cases.

Thermodynamic study of heavy metals behavior during municipal waste incineration [PDF]

, 2005
The incineration of municipal solid waste (MSW) contributes significantly to the presence of heavy metals in urban area aerosols. It is thus important to ascertain the quantities and chemical forms of the heavy metals (HM) that are emitted from the ...
