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

Colors from the Past: Ion Beam Analyses on Glass Finds Excavated at the Late Iron Age Settlement from Tinosu, Prahova County, Romania

ChemPlusChem, EarlyView.
Particle induced X‐ray emission‐Particle induced gamma‐ray emission analyses of 20 glass fragments from monochrome or millefiori vessels and adornments from the Late Iron Age site from Tinosu, Romania (1st c. BC and 1st c. AD) indicates compositions similar to coeval Hellenistic and Roman glass finds , suggestive for imports.

N‐Aryl or N‐Alkyl Pyridinium‐Substituted Excited‐State Intramolecular Proton Transfer Fluorophores

ChemPlusChem, EarlyView.
This article describes the synthesis of a series of fluorophores consisting of N‐alkyl or N‐aryl pyridinium groups connected at different positions of a 2‐(2′‐hydroxyphenyl)benzoxazole scaffold and the exploration of the photophysical properties in solution (dichloromethane) and in the solid state as amorphous powders.

Interplay between Structure and Conduction Mechanism of Piperazinium‐Functionalized Poly[Ethylene Pyrrole/Ethylene Ketone/Propylene Ketone] Anion Conducting Membranes

ChemSusChem, EarlyView.
A new anion exchange membrane based on random piperaziniumethyl N‐substituted poly[ethylene pyrrole/ethylene ketone/propylene ketone] (P‐FPKK), with a conductivity of 11.3 mS cm−1 at 60 °C in hydroxyl form, is developed. This material is very promising to overcome the issue of anionic membranes as potential alternatives to proton exchange membranes in ...
