The 'Second Shift' Is Not Why Women Avoid News
Women are more likely than men to avoid political and economic news, but the reasons for this behaviour are linked less to structural inequality or family-related stress than to personal attitudes and the emotional perception of news content. This conclusion was reached by HSE researchers after analysing data from a large-scale survey of more than 10,000 residents across 61 regions of Russia. The study findings have been published in Woman in Russian Society.

Синтез Fe-ZIF и особенности сорбции ионов цинка и меди на его поверхности

Журнал неорганической химии. 2023. Т. 68. № 7. С. 939–945.
Vashurin A., Карасева А. А., Филиппов Д. В.

A method for the synthesis of a zeolite imidazolate framework based on Fe(III) at various metal/linker ratios is proposed, which is used as a sorbent for the extraction of zinc(II) and copper(II) ions. For the obtained materials, it was found that the particles have a hexagonal structure and represent a microheterogenic system with an average particle size of 0.05–0.1 microns. Nitrogen adsorption isotherms in Fe-ZIF pores have been obtained. As a result of their processing, the parameters of the porous structure of the synthesized samples were found. The adsorption of Cu2+ and Zn2+ ions from aqueous solutions at a temperature of 298.15 K was studied and their high degree of extraction was shown. The adsorption of copper and zinc ions is spontaneous in all cases. The maximum degree of filling of the active centers of the surface reaches 0.96 and 0.71 for copper and zinc, respectively. The course of adsorption in the volume of an energetically homogeneous porous adsorbent and the predominance of micropores in the structure of 2-ethylimidazolate of iron(III) have been established.

A new approach to managing the extraction properties of eutectic solvents based on aliphatic alcohols is proposed. Aliphatic alcohols, when functioning as hydrogen bond donors within a eutectic solvent, significantly enhance the solvent’s efficiency in extracting metal ions. Conversely, when the alcohol acts as a hydrogen bond acceptor, its extraction properties diminish. Molecular modelling reveals ...

Садртдинова Г. И., Nifantiev I., Vinogradov A. et al., Russian Chemical Reviews 2025 Vol. 94 No. 9 P. 1 – 55
The reactivity of polar vinyl monomers, unsaturated compounds containing functional groups, depends on the presence or absence of conjugation between the C=C bond and the neighbouring unsaturated moieties or donor heteroatoms. Conjugated polar vinyl monomers (acrylates, vinyl ethers, etc.) (co)polymerize upon free-radical initiation. The reaction is widely used to produce numerous polymer materials that qualitatively differ ...

Cu(I) acetylide clusters decorated with pyridylphosphine ligands: structural diversity, cuprophilic interactions and phosphorescence properties
Baranov A., Bagryanskaya I., Novikov A. et al., Inorganic Chemistry Communications 2026 Vol. 189 Article 116670
The reaction of copper(I) phenylacetylide [PhC ≡ CCu]n with the 2-pyridylphosphines (tBu2PyP and Ph2PyP) offers a straightforward route to structurally diverse clusters. With tBu2PyP, a trinuclear cluster [Cu3(C ≡ CPh)3(tBu2PyP)3] featuring a Cu3 triangular was isolated. Surprisingly, the reaction of [PhC ≡ CCu]n with Ph2PyP yields two isomeric clusters [Cu4(C ≡ CPh)4(Ph2PyP)4] with tetrahedral or zigzag-arranged Cu4 cores. Upon prolonged storage in acetonitrile, the tetrahedral Cu4 cluster converts to ...

Dipolar [3+2] Cycloaddition of Nitrones to 3-Aroylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-triones
Khramtsova E. E., A. S. Novikov, Dmitriev M. V., Russian Journal of Organic Chemistry 2026 Vol. 62 Article 12
The dipolar [3+2]-cycloaddition reactions of 3-aroylpyrrolo[2,1-c][1,4]benzothiazine-1,2,4-triones with diarylnitrones lead to the formation of benzo[b]isoxazolo[5',4':2,3]pyrrolo[1,2-d][1,4]thiazines. The reac- tion proceeds stereoselectively to form exclusively the (2aS*,3R*,5aS*) diastereomers. Density functional theory computations for the model reaction showed that the (2aS*,3R*,5aS*) diastereomers are both kinetically and thermodynamically preferred over the alternative (2aS*,3S*,5aS*) diastereomers. At room temperature in solution, the ...

The interaction of the PBr3 molecule with Si dangling bonds (DBs) on a chlorinated Si(100) surface was studied. The DBs were charged in a scanning tunneling microscope (STM) and then exposed to PBr3 directly in the STM chamber. Uncharged DBs rarely react with molecules. On the contrary, almost all positively charged DBs were filled with molecule fragments. ...
