ChemCatChem, Volume 18, Issue 5, 13 March 2026.MoO3 is active for hydrodeoxygenation of phenol at high temperatures. Ru/MoO3 gives high conversions and selectivities at lower temperature. Catalytic performance correlates with both Ru content and the concentration of Mo–OH sites on the surface (formed by hydrogen spillover from Ru) but not with the amount of reduced Mo centers (oxygen vacancies). Mo–

Geoarchaeology, Volume 41, Issue 2, March/April 2026.ABSTRACT This study presents new evidence for the early use of lime mortar during the Early Iron Age at the Piscina Torta site (Ostia, Italy), situated on the earliest Holocene beach ridges in the southern Tiber delta. The site, which was earlier described as a briquetage site, dates from between the late 8th and 6th century BCE and consists of a large
