The Eastern-sigillata samples exhibited the best quality. The small size of the pores and inclusions suggests the use of finely dispersed clay. In addition, a mixture of two types of clay (ferrous and more refractory calcareous) was revealed. The special and, apparently, careful preparation of the clay suspension for the slip layer production included addition of a potassium-containing preparation, presumably, potassium potash (to glaze better the layer), as well as an iron-containing pigment, likely, ochre. The firing temperature for this group of samples was about 1000°C. Pontic sigillata products differed from the Eastern pottery by a lower content of potassium potash and the absence of specially added pigment in the varnish layer. The firing temperature was lower: 850–900°C. The Bosporan products are characterized by much less thorough preparation of both the clay raw material as a base and the varnish layer, as well as the lowest firing temperature in comparison with other groups (500–900°C).","PeriodicalId":527,"journal":{"name":"Crystallography Reports","volume":"69 6","pages":"988 - 997"},"PeriodicalIF":0.6,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143423489","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Despite the different purposes of the structures (the tomb on the Eski-Kermen plateau was built inside an existing building, the outer walls of the tomb in Gorzuvit were “built up” to increase the internal space volume), lime mortar was used in both cases. The faunal remains found in the lime base made it possible to clarify the origin of the carbonate raw material used. The lime mortar used on Eski-Kermen was prepared from the Eocene nummulitic limestone, from which, in particular, the plateau itself is composed, while in Gorzuvit the limestone of the Upper Oxfordian deposits of the southern slopes of the Main Ridge of the Crimean Mountains was applied. Rounded large pebbles (of river or sea origin), sand (presumably of river origin), and plant remains were used as technological admixtures in Gorzuvites. On the Eski-Kermen plateau, due to limited resources, mainly only heterogeneous, fairly large fragments of crushed, partially burnt ceramics are found. The obtained results confirm the hypothesis that the local changes in the mortar composition are associated with the availability of raw materials near the construction site, of both natural and anthropogenic origin.","PeriodicalId":527,"journal":{"name":"Crystallography Reports","volume":"69 6","pages":"998 - 1006"},"PeriodicalIF":0.6,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143423492","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The interest in these ligands is caused by their potential biological activity and possibility of using them in pharmaceutics. The composition of the synthesized metal complex is found to be [Cu(1,10-phen)2NO3](C8H8O3⋅NO3), as confirmed by elemental analysis. The molecular and crystal structures of the complex are studied by X-ray diffraction (XRD). Its crystallographic characteristics, bond angles, lattice parameters, and geometry of hydrogen bonds are determined. The data obtained made it possible to construct a 3D model of the material.

The changes in the molecular organization of monolayers of two neutral phospholipids—dipalmitoylphosphatidylcholine and dipalmitoylphosphatidylethanolamine—after the injection of a protein solution underneath the monolayer have been analyzed. Experiments were performed with a recombinant ectodomain of the S-protein, expressed in a CHO-K1 cell strain. Electron microscopy data showed that the protein is trimerized. Grazing incidence diffraction measurements were performed to study the influence of the trimer ectodomain of the S-protein on the structure of the dipalmitoylphosphatidylcholine monolayer. It is found that protein injection under the monolayer does not induce disturbance of the monolayer crystal structure. The experimental results obtained in X-ray studies and compression isotherm measurements indicate that the interaction with the S-protein does not result in destabilization of the monolayer for both phospholipids.","PeriodicalId":527,"journal":{"name":"Crystallography Reports","volume":"69 6","pages":"931 - 938"},"PeriodicalIF":0.6,"publicationDate":"2025-02-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143423372","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The ordering of Ca, Fe, Mn, and Na atoms in octahedra of six-membered rings, as well as Zr and Na atoms in M2 positions at the centers of square pyramids, with a common base, formed by the edges of these octahedra, has been established with the P3 symmetry. The trigonal unit cell parameters are a = 14.222(3) Å, c = 30.165(5) Å, and V = 5283.9 Å3. Taking into account the new data, the studied low-calcium eudialyte can be assigned to the subtype of oneillite or raslakite, being a high-zirconium variety of the latter. The study of the structure of this mineral in rhombohedral symmetry (sp. gr.
