A Multi‐Analytical Approach for the Compositional Characterization and Chronological Discrimination of Benin (Nigeria) Metal Sculptures

Archaeometry, Volume 68, Issue 5, Page 1022-1036, October 2026.
ABSTRACT This study presents a multi‐analytical archaeometric approach for the compositional characterization and chronological discrimination of Benin metal sculptures in relation to the 1897 Punitive Expedition. The methodology integrates elemental composition (XRF and ICP), stable lead isotope ratios (MC‐ICP‐MS) for alloy system characterization ...

Application of Multi‐Method Dating for Understanding the Gravettian North of Moravia, Central Europe

Archaeometry, Volume 68, Issue 5, Page 1050-1061, October 2026.
ABSTRACT This article presents the results of integrating three methods to assess the age of the Upper Palaeolithic site of Pietraszyn 11 (SW Poland), close to the Moravian Gate. Sediment chronology determined using optically stimulated luminescence produced promising, yet ambiguous results (51.0 ± 3.7 to 20.3 ± 0.7 ka).

Graphene Oxide Membranes for Critical Raw Materials Recovery and Water Purification: From Cleanroom Wastewater to Fluorite

Advanced Energy and Sustainability Research, Volume 7, Issue 9, September 2026.
This study demonstrates a closed‐loop membrane process using functionalized graphene oxide to purify semiconductor wastewater and recover high‐purity fluorite ( CaF2), a critical raw material. By reducing fluorine levels from 21 to 1.4 mg L−1, meeting strict international safety standards, the method successfully transformed hazardous waste into a ...
