Chemical composition of potassium-glass vessels from the 14th-15th centuries found in Tartu, Estonia
Publikováno v:
Journal of Archaeological Science: Reports. 38:102978
XRF-analysis of 18 fragments of several 14th–15th-century vessel types and an additional fragment of a 16th-century glass vessel, found primarily from the cesspits in the medieval town centre of Tartu, was carried out. The study reveals that these

Fragments of five enamelled glass beakers found from the Estonian towns Viljandi and Tartu have been studied by using Raman spectroscopy, optical absorption and X-ray fluorescence methods. The beakers of 13th–14th–century dating are made of soda-

Stacking order of multilayer graphene (MLG) has attracted elevated interest because one can expect that rotationally faulted MLG has the charge transfer properties similar to those of single layer graphene. In our work, we studied MLG stacking on Ni

Graphene growth by chemical vapor deposition on low cost metal foils is a promising approach for the production of large-scale graphene. However, the precise control of the uniformity of synthesized mono- and multilayer graphene requires elucidation

New corrosion-resistant hybrid coatings based on graphene and polypyrrole were prepared and studied. A two-step process was used to fabricate the coatings. First, graphene was grown on a commercial copper foil by chemical vapor deposition (CVD) metho
