The findings originate from the destruction layer of the late 13th century AD as well as from two churches and a manor of a noble citizen. The studied samples are made of Eastern Mediterranean plant ash glass, mainly of the Levantine origin, and of glass with high concentrations of boron and lithium, which origin is associated with Western Anatolia. It does not necessarily imply that the vessels themselves originate from these glassmaking regions, because raw glass, at least Eastern Mediterranean (Levantine), was a long-distance trade commodity and could have been imported into Byzantium or elsewhere. Glass of presumably Western Anatolian origin is heterogeneous in composition and likely originate from glassmaking centers that used raw materials from different sources. Most glass of this group features signs of the extensive recycling. The glass with a high B and Li content appears in Esky-Kermen in the 10th century AD at the latest. According to an earlier study of window glass composition from the site, its emergence here before the 13th century remained doubtful. Two early Islamic marvered vessels are made of glass with elevated content of boron and lithium, featuring signs of recycling. Such examples have already been recorded earlier among glassware made in this style from Pergamon and Branichevo in Serbia. This raises the question of possible manufacturing centers for some vessels with marvered décor.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"19 4","pages":"593 - 605"},"PeriodicalIF":0.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://link.springer.com/content/pdf/10.1134/S2635167624601815.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489566","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study focused on the spring wheat collection from the Omsk Agricultural Research Center. Through genotyping of the collection and statistical analysis of field data from 2022 and 2023, it was determined that the translocation 1RS.1BL and the TaGS2-A1a allele exert the most substantial positive influence on plant productivity and spike structure. The effect of the TaGS2-A1a allele was more pronounced in plants lacking the translocation 1RS.1BL: the difference in grain weight per spike between the TaGS2-A1a and TaGS2-A1b alleles ranged from 0.2 to 0.5 g (18 to 56%). Additionally, the influence of VRN-B1 on heading dates was more significant in plants without the translocation: those with the spring allele Vrn-B1 outpaced plants with the winter allele vrn-B1 by three days. Therefore, the presence of the translocation 1RS.1BL appears to mask the phenotypic expression of TaGS2-A1 and VRN-B1. Plants carrying the allelic combination TaGS2-A1a+1RS.1BL+vrn-B1 demonstrated greater productivity than other allelic combinations.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"19 5","pages":"796 - 807"},"PeriodicalIF":0.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489602","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This work assesses the effect of graphene oxide (GO) and multi-walled carbon nanotubes (MWCNTs) on the growth, viability, oxidative stress, and content of photosynthetic pigments in the cells of a common microalga of the genus Desmodesmus. The study shows differences in the effects of different carbon nanomaterials at the same concentrations. Thus, GO does not have a negative effect on the viability and cell growth of the microalga Desmodesmus armatus with the exception of an increase in the level of oxidative stress, which ultimately affects growth of the culture. At the same time, when MWCNTs are added at concentrations of 100 and 1000 μg/L, a significant decrease in the growth of the cell number is recorded already on the 7th day of the experiment, with the effect maintained at the end of the experiment (14th day). At the same concentrations, a significantly higher level of oxidative stress is observed on the 14th day of the experiment. The analyzed CNMs do not have a reliable effect on the content of photosynthetic pigments. Thus, in the studied concentrations, GO turns out to be practically safe for the studied microalgae, unlike MWCNTs, which show noticeable toxicity. This can be taken into account in the future when developing practical applications for such CNMs, and can also be used in environmental regulation of their content in the environment.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"19 5","pages":"675 - 682"},"PeriodicalIF":0.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489402","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

(2n = 6x = 42) and the tetraploid durum wheat Triticum durum (2n = 4x = 28) are two commercially the most important wheat species worldwide. These two species are components of the same gene pool, which evolved under different conditions, which made it possible to acquire different adaptations to a wider range of environmental conditions. Identification and characterization of introgressed fragments of one species in the genome of another can help in the search for new loci responsible for economically valuable traits. Single nucleotide polymorphism (SNP) microarrays provide information on the genotypes of thousands of positions throughout the genome. This information can be used to obtain the distribution of alleles of one species in the genome of another and to determine the location of introgressed fragments. In our work, we used genotyping data from the SNP microarray to identify durum wheat chromosome fragments containing bread wheat alleles in the offspring from crossing bread and durum wheat. We have studied the distribution of the genetic material of bread wheat in 15 combinations from crosses of bread and durum wheat. Introgressed fragments of bread wheat into the durum wheat genome were identified on chromosomes 1A, 1B, 4A, 5B, 6B, and 7A. The introgressed fragments showed polymorphism in different breeding lines. A functional enrichment analysis of genes in the introgression fragments showed the presence of statistically significant enrichment of genes responsible for various molecular functions, biological processes and cellular components. The obtained data can be used to identify new QTL of economically valuable traits for obtaining durum wheat varieties with improved agronomic traits.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"19 5","pages":"830 - 842"},"PeriodicalIF":0.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489600","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This is due to the wide area of its growth and dominant position in terms of reserves in the Russian Federation. However, there are technological difficulties associated with its use as a building material due to the peculiarities of its structure and properties. Approaches to studying the physical and mechanical characteristics of wood from the nanolevel to macrolevel are demonstrated. They are focused on identifying the features of the microstructure and their relationship with the physical and mechanical characteristics at various structural levels. Using the dynamic nanoindentation and scratch-test methods, the values of the hardness and Young’s modulus are obtained from the cell wall level to the ring structure of larch wood. At the levels above individual cell wall both characteristics are found to be several times higher in late wood that in early one within annual growth ring. It is shown that the accuracy of determining the width of annual rings from the obtained profile of mechanical properties is no worse than the standard optical method. This makes it possible to use the proposed approach to solve problems of dendrochronology and its related disciplines.","PeriodicalId":716,"journal":{"name":"Nanotechnologies in Russia","volume":"19 5","pages":"708 - 718"},"PeriodicalIF":0.8,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489361","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
