Archaeometric Analyses of Medieval Pottery From the Lower Danube Region, Romania
ChemPlusChem, Accepted Article.This paper discusses the pottery manufacturing in the Lower Danube region during the Early Medieval period. Optical Microscopy (OM), Particle Induced X‐ray Emission (PIXE) and X‐ray Diffraction (XRD) were performed on thirty‐two ceramic shards unearthed at Pantelimonu de Sus, Romania, dated to the 8th‐10th c. AD. The petrographic observations showed an

Phenol‐Rich Carbon Dots as Metal‐Free Nano‐Photocatalysts for [3 + 2] Cycloaddition Reactions
ChemSusChem, EarlyView.Phenol‐rich carbon dots can be effectively used, in combination with a proper base and the Schreiner thiourea (A), as nano‐photocatalysts to drive synthetically relevant [3 + 2] cycloaddition reactions between cyclopropyl ketones 1 and unsaturated hydrocarbons 2. Carbon dots (CDs) are unique carbon‐based nanoparticles with potential applications in the
