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.

Outline of a Washing Treatment to Improve Electric Arc Furnace Slag Environmental Behavior

steel research international, Volume 97, Issue 5, Page 2541-2558, May 2026.
This study evaluates a water‐washing treatment for electric arc furnace slag to reduce the leaching of hazardous elements (Cr, Ba, Mo, and V), enabling its reuse. The process effectively decreases leachate concentrations. Using the treated slag as a substitute aggregate in concrete reduces greenhouse gases emissions by 42.5% compared to landfilling ...

3D‐Printed Geopolymer as a Basic Heterogeneous Catalyst for the Synthesis of α‐Cyanoacrylates Through the Knoevenagel Condensation

European Journal of Organic Chemistry, Volume 29, Issue 16, 25 April 2026.
3D‐printed geopolymers are presented as efficient and reusable heterogeneous catalysts for the Knoevenagel condensation. Under mild and green conditions, they promote the high‐yield synthesis of diverse α‐cyanoacrylates with remarkable stability and scalability.

Tracking the Dynamics of human Colonisation and Adaptation in Central Vanuatu: Preliminary Results From Excavation and Survey at Pangpang, East Efate

Archaeology in Oceania, Volume 61, Issue 1, Page 221-236, April 2026.
ABSTRACT In October 2022 an extensive archaeological landscape was identified by staff of the Vanuatu Cultural Centre at Pangpang on the east coast of Efate Island in central Vanuatu. It included midden deposits on the banks of the Pangpang River near the sea at Forari Bay where Lapita and Early Erueti‐style pottery sherds were recovered.
