A POSSIBLE AMPHORA FRAGMENT FROM 6TH CENTURY BALATONLELLE, WESTERN HUNGARY [EGY LEHETSÉGES AMPHORA TÖREDÉK A 6. SZÁZADI BALATONLELLÉRŐL] JF - ARCHEOMETRIAI MŰHELY J2 - ARCHEOMETRIAI MŰHELY VL - 21 PY - 2024 IS - 2 SP - 201 EP - 216 PG - 16 SN - 1786-271X DO - 10.55023/issn.1786-271X.2024-016 UR - https://m2.mtmt.hu/api/publication/34839820 ID - 34839820 AB - This study reports on a unique finding connected to the re-examination of the ceramic assemblage recovered from the Langobard age (6th century AD) settlement of Balatonlelle, situated in the territory of the former Roman province of Pannonia (now in western Hungary). An undecorated body sherd, not picked up by either the initial typological evaluation of the ceramics or by the preliminary petrographic analysis, was now reassessed by thin section ceramic petrography and scanning electron microscopy. The new analyses revealed that this sherd contains rock and mineral inclusions originated from ophiolites, including slightly serpentinised peridotite fragments. Such rocks do not occur on the surface in Hungary, whereas they are commonly found in the Eastern Mediterranean. The presence of ophiolites in the potsherd indicates that this vessel was produced in a distant territory. The macroscopic characteristics of the sherd combined with its petrographic fingerprint suggest that this pot might have been a transport amphora produced in the Eastern Mediterranean. Although rarely found in Pannonia in the Migration Period, several amphora types, including the most frequently found LRA 1 type, were produced in numerous production centres in the Eastern Mediterranean, in territories geologically congruous with the aplastic inclusions found in the fabric of the Balatonlelle sherd. The significance of this finding is that from Langobard age Pannonia, amphorae occur only sporadically, connected mainly to former Roman settlements. While any conclusions drawn from a single sherd must necessarily remain tentative, this sherd nonetheless provides some material evidence for the existence of some sort of contact between Balatonlelle and the Eastern Mediterranean during the 6th century, be it economic, political or cultural. This study also aims to celebrate the career of György Szakmány, who was one of the key figures to establish ceramic petrographic research and education in Hungary, and trained many generations of petrographers – including the present authors. As such, it also serves as an example how ceramic petrography can bring a new dimension of information to archaeological research. LA - English DB - MTMT ER - TY - JOUR AU - Li, T. AU - Zhang, Y.

For detailed characterization of such materials, a set of techniques is used, such as transmission electron microscopy, atom probe tomography, as well as small-angle scattering of X-rays and neutrons. The latter techniques make it possible to analyze the largest volume of material, while maintaining the ability to detect various nanoscale features. Since ferritic-martensitic oxide dispersion-strengthened steels are ferromagnetic materials, magnetic scattering has to be taken into account in the processing of small-angle neutron scattering data. The nanostructure of ferritic-martensitic oxide dispersion-strengthened steels with different alloying systems (different content of Cr, V, W, Al, and Zr) is investigated by small-angle neutron scattering. A comparison of the results of the study of the nanostructure of steels (oxide particles and clusters) in the ferromagnetic state with and without magnetic scattering is carried out. It is shown that oxide particles have a significantly higher magnetic contrast in comparison with nanoscale clusters. At the same time, the most accurate hardness values can be obtained by taking into consideration of both oxide inclusions and clusters. © Pleiades Publishing, Ltd. 2024.

However, the current drawbacks of this approach prove the need for further research and development in the field. Herein, novel ternary solid polymer electrolytes have been developed using varying loads of MOF-808 metal-organic framework and [BMIM][SCN] ionic liquid (IL) incorporated in a poly(vinylidene fluoride-co-hexafluoropropylene) matrix. The solid polymer electrolytes were evaluated at morphological, structural, thermal, mechanical and electrochemical levels, and their performance in cycling battery testing was assessed. The results showed a homogeneous structure throughout all the samples and a good dispersion of the distinct components. The polymer polar phase and degree of crystallinity of the samples are increased with increasing IL content, and the thermal and mechanical properties are appropriate for battery application. The ionic conductivity of the samples reaches maximum values of 4.68 × 10−5 S‧cm−1 at room temperature, lithium transference numbers up to 0.65, and high electrochemical stability, making them well-suited for battery applications. The assembled stability after 50 cycles at C/10 with a discharge capacity value of 150 mAh‧g−1 at room temperature was tested/derived. The obtained results show the potential of this system for high performance room temperature solid polymer electrolytes.

The steels under study have different alloying systems differing in their contents of Cr, V, Ti, Al, and Zr. The methods of local analysis of TEM and APT revealed a significant number of nanosized oxide particles and clusters. Their sizes, number densities, and compositions were determined. A calculation of hardness from SANS data collected without an external magnetic field, or under a 1.1 T field, showed good agreement with the microhardness of the materials. The importance of taking into account two types of inclusions (oxides and clusters) and both nuclear and magnetic scattering was shown by the analysis of the scattering data. © 2024 by the authors.
