Background: Three-dimensional (3D) printed crystal structures are useful for chemistry teaching and research. Current manual methods of converting crystal structures into 3D printable files are time-consuming and tedious. To overcome this limitation, we developed a programmatic method that allows for facile conversion of thousands of crystal structures directly into 3D printable files.

In general, Ukrainian and Russian populations of Slobozhanshchina genetically are very close, their set and frequency range of Y-chromosome haplogroups are typical for the Eastern Europe. But a detailed analysis of highly informative Y-chromosome markers showed that after 3,5 centuries of coexistence on the same historical territory, the both nations retain the ethnic specificity of their gene pools: Ukrainian populations are similar to the rest of Ukraine, and Russian populations are similar to the south of the European part of Russia.

- The Slavic languages diverged rapidly due to the expansion of speakers from Central-East Europe during medieval times, incorporating genes from local populations in Eastern Europe and the Balkans.
- Genetic analysis on various ethnic groups speaking Balto-Slavic languages revealed a strong correlation between genetic distances and geography (0.9), while showing a slightly lower correlation with mitochondrial DNA and language (0.7).
- The study indicates that present-day Slavic genetic diversity was shaped locally, identifying two main gene pools: 'central-east European' for West and East Slavs and 'south-east European' for South Slavs, with evidence of shared ancestry and gene flow between East-West and South Slavs.
The area of what is now the Ukraine has been the arena of large-scale demographic processes that may have left their traces in the contemporary gene pool of Ukrainians. In this study, we present new mitochondrial DNA data for 607 Ukrainians (hypervariable segment I sequences and coding region polymorphisms). To study the maternal affinities of Ukrainians at the level of separate mitochondrial haplotypes, we apply an original technique, the haplotype co-occurrence analysis.
