Archaeometric Analyses of Medieval Pottery from the Lower Danube Region, Romania

open access: yesChemPlusChem, EarlyView.
This study is about the pottery manufacturing in the Lower Danube region during the Early Medieval period (8th–10th c. AD). Optical microscopy, Particle induced X‐ray emission, and X‐ray diffraction analyses performed on 32 representative ceramic shards excavated at Pantelimonu de Sus, Constanţa County, Romania, provide clues on the raw materials and ...

From Green to Brown: Characterization of the Fast Alteration of Modern Greenish Enamels in Glass Windows

open access: yesChemPlusChem, EarlyView.
Spots and stains appeared on the modern green enamel from different stained‐glass windows as a consequence of environmental alteration. The multianalytical characterization showed a 3‐step alteration mechanism divided into Pb2+ lixiviation from the enamel, formation of hydrocerussite (2PbCO3·Pb(OH)2), and transformation into scrutinyite (α‐PbO2) and ...

Can Chain Leaders Stop Greenwashing Practices in Supply Chain Governance? An Empirical Investigation Into Business Strategies

open access: yesCorporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT In the context of the global green transformation of supply chains, corporate greenwashing has exhibited a networked diffusion trend, yet the role of chain leaders in this governance process remains unclear. Based on resource orchestration theory (ROT), this study uses data from Chinese A‐share listed firms and their supply chain partners ...

Modelling Thomson Scattering in a Hydrogen Plasma at Stellar Interior Conditions Using the Hypernetted‐Chain Approach

open access: yesContributions to Plasma Physics, EarlyView.
ABSTRACT Under the extreme conditions found in small stars, where electron degeneracy and Coulomb coupling are significant, accurate modeling of Thomson scattering is crucial for determining opacity, a primary quantity for stellar energy transport.
