Pocket Money, Personal Interest, and Family Practices: What Shapes Students Economic Literacy?
University students' economic literacy depends not only on their field of study but also on their interest in economics, the learning environment, and family financial practices. For example, students who received pocket money irregularly tend to perform better on economic literacy tests than their peers who received financial support on a regular basis. These findings come from a study conducted by HSE University involving more than 1,100 students from five Russian universities. The findings have been published in Cakrawala Pendidikan.

Phenyl substitution as an effective way to control the luminescent properties of polyphenylcyclopentadienyl lanthanide complexes

Mendeleev Communications. 2024. Vol. 34. No. 3. P. 325–328.
Puntus L., Daniil A. Bardonov, Varaksina E., Ilya V. Taydakov, Dmitrii M. Roitershtein, Ilya E. Nifant’ev, Konstantin A. Lyssenko

Lanthanide complexes [CpXLnCl2(Me3tach)]n (Ln = Tb, Gd; CpX = Cp, CpPh, CpPh; Me3tach = 1,3,5-trimethyl-1,3,5- triazacyclohexane; n = 1, 2), containing cyclopentadienyl (Cp), 1,3-diphenylcyclopentadienyl (CpPh) and tetraphenyl- cyclopentadienyl (CpPh) anions as ν-bonded antenna ligands, have been synthesized. A combined analysis of quantum chemical, optical and X-ray diffraction data has shown that the introduction of phenyl groups into the Cp ring leads to the inevitable appearance of intraligand charge transfer states due to the nonequivalence of the phenyl rings.

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 ...
