An original phenobarbital anticonvulsant Halonal, 5-ethyl-1-(2-fluorobenzoyl)-5-phenylpyrimidine-2,4,6(1H,3H,5H)-trione, stimulated the cellular immune and the humoral response in long-term alcoholized male (CBAxC57Bl/6) F1 mice to the level of healthy animals. Voltammetry was found to be suitable for determination of Halonal R/S-enantiomeric ratio, which was exemplified on the authentic sample with the R/S-composition of 40:60. Molecular docking (Schrödinger program, Glide) showed that Halonal behaved as a benzonal derivative interacting with GABAAR via the BARB binding site, with S-Halonal having higher similarity score than its R-enantiomer because of a different orientation of the 2-fluorobenzoyl substituent.

Two thermostable representatives of methyl-substituted triazolofurazan derivatives with zwitterionic N+N– bonds were obtained via the thermal cyclization of N,N’-bis(azidofurazanyl)-N-methyltriazene. 5-(N-Azidofurazanyl-N-methylamino)triazolofurazan was the product of known intramolecular reaction of neighboring azido and azo groups. Its isomer with methyl group in the triazolofurazan core was formed in the course of new cyclization of azido and triazene groups representing an original NN bond formation reaction giving an unusual zwitterionic heterocyclic system.

A 3D printed microreactor and UV-VIS spectral diagnostic system were adapted for an automatic protocol for screening parameters of citrate-based droplet synthesis of gold nanoparticles. Using this system, 27 combinations of synthesis parameters were screened within an hour and data were collected from more than 1000 individual droplets with nanoparticles. The developed system allows both filtering the spectra of target droplets and conducting a comprehensive multivariate analysis of all key descriptors.

The calculation of the electronic structure of MdO2 was carried out using the fully relativistic method of discrete variation (RDV), a scheme of molecular orbitals (MO) was built and a histogram of the spectrum of X-ray photoelectron spectroscopy (XPS) was constructed in the range of electron binding energies (BE) 0–∼40 eV. It was discovered that the complex structure of the XPS spectrum of valence electrons is associated with the formation of the outer valence molecular orbitals (OVMO, BE from 0 to ∼15 eV) and of the inner valence molecular orbitals (IVMO, BE from ∼15 to ∼40 eV). The effective charge of Md in MdO2 calculated from the MO compositions was equal to +0.50 electrons. IVMO electrons were found to weaken the bond formed by OVMO in MdO2 by ∼34%.

Acidic deep eutectic solvent was prepared from choline chloride and trifluoromethanesulfonic acid at room temperature. Reaction between aromatic aldehydes and arylacetylenes in this solvent gave chalcones whose in situ reaction with sodium arenesulfinates in water successfully provided γ-keto sulfones in good yields. This deep eutectic solvent could be easily recovered and reused for several runs.

The ionic liquid choline cinnamate was applied for the first time as a defect passivator in light-absorbing layers of perovskite solar cells (PSCs). It was found that bulk passivation with an addition of 0.5% ionic liquid notably enhances the photothermal stability of PSCs, while surface passivation leads to the opposite effect with the loss of device stability, due to the complex origin of the influence of choline cinnamate on the defect structure and microstructure of hybrid halide perovskites.
