Features of gas chromatographic analysis of thermally unstable compounds.

Confirming the stability of analytes during gas chromatographic (GC) analysis is an important criterion, especially for previously uncharacterized compounds. However, the variations of absolute peak areas at different injector temperatures usually do not allow us to reveal the thermal instability of analytes during GC analysis. Such variations may be caused by peak area known discrimination typical for using capillary columns, especially at low split injection.

A new pseudopolymorph of berberine chloride: crystal structure and Hirshfeld surface analysis.

A new pseudopolymorph of berberine, 9,10-dimeth-oxy-5,6-di-hydro-2-7λ-[1,3]dioxolo[4,5-]iso-quinolino-[3,2-]isoquinolin-7-ylium chloride methanol monosolvate, CHNO ·Cl·CHOH, was obtained during co-crystallization of berberine chloride with malonic acid from methanol. The berberine cations form dimers, which are further packed in stacks. The title structure was compared with other reported solvates of berberine chloride: its dihydrate, tetra-hydrate, and ethanol solvate hemihydrate.

Cross-Cultural Comparison of Relationships between Empathy and Implicit Theories of Emotions (in Chinese and Russians).

The current manuscript presents the results of a cross-cultural comparison of the relationships between empathy and implicit theories of emotion in individuals from China and Russia. We hypothesized that the members of the Chinese culture would differ from the more Western Russian participants in terms of relationships between the various components of the emotional domain. Thus, we aimed to identify latent personality profiles while hypothesizing that the Chinese sample would demonstrate more prominent links between empathy and implicit theories regarding the possibility of controlling emotions.

Personality regulation of decisions on physical distancing: Cross-cultural comparison (Russia, Azerbaijan, China).

The present study investigated cross-cultural comparison of the personality variables (rationality, risk readiness, empathy, Dark Triad traits, implicit theories of emotions) in predicting decisions on physical distancing during the COVID-19 pandemic. The sample included 1077 participants from Russia, Azerbaijan, and China. After reporting if they trust the media, participants chose from different reasons why they wear or don't wear a mask: care for self vs others, risk for oneself vs others, autonomy for oneself vs others, risk estimation, law-abidingness; then participants completed questionnaires.
