Graphical Abstract: The aim of this research work was to evaluate the role of different fractions of humic substances in the binding of Al(III), Fe(III) and Cu(II) ions into complexes. The share of humic substances with a molecular weight of 20–5 kDa increases from 37% to 59%, when the total concentration of humic substances also increases. It was established that humic substances with molecular weight 20–5 kDa bounded the smallest amount of Al(III), Fe(III) and Cu(II) into complexes.

Graphical Abstract: The Pseudo-Jahn-Teller-Effect governs the glutamate mutase and methylmalonate-CoA mutase preliminary step and provides insight into particular details of in vivo C-N bond cleavage reactions of the adenosylcobalamin cofactor. Multi-configurational self-consistent field (MCSCF) calculations show that the preliminary step reaction glutamate mutase and methylmalonate-CoA mutase processes occur in the absence of total energy barriers.

Graphical Abstract: The degradation of diisopropyl methylphosphonate (DIMP) in aqueous solutions was studied using ultrasound irradiation with a fixed frequency of 26.6 kHz, following the first-order kinetic model. The experimental parameters, including the pH, the initial concentration of DIMP, the processing time, and the concentration of the additive CCl4 were investigated. The best degradation efficiency of 98% was observed at pH of 10, adding 0.8 g/L CCl4 for a processing time of 45 min.

plant extract, phenolic compound, antioxidant, biodiesel, oxidation stability.

Graphical Abstract: The extracts from the leaves of Deschampsia antarctica, Camelina sativa, and Camellia japonica plants, as well as from Camelina sativa and Silybum marianum seedcakes were investigated as potential additives for improvement of biodiesel stability against oxidation. In spite of significant distinctions in the content of various phenolic compounds, all the extracts were found to effectively inhibit DPPH radicals and decelerate transformation of fatty acid esters of biodiesel into organic acids by ~9-26%. Various extracts were shown to have different activity towards the biodiesel from rape and camelina seed oils; this result is consistent with the assumption that there is no universal stabilizer for different types of biodiesel.

Full Text (PDF): Download
Graphical Abstract: DFT computations identify the effects that enable the synthesis of geometrically-strained epoxide from deprotonated halohydrins. These computations also explain the preference for the formation of larger cyclic ethers with five-atom rings over six-atom-rings. Increased temperature favors elimination over SN2 only when the reacting moieties are part of separate molecules.

Graphical Abstract: The crystal structure of 1,5-bis(2-hydroxy-3-methoxybenzylidene) carbonohydrazide (1) was determined by X-ray single crystal diffraction study. In solid-state the molecule adopts the anti keto conformation, while NMR studies proved evidence on the presence of its syn tautomer in DMSO solution.

Graphical Abstract: In this paper the process of reagent desalination of mineralized mine waters was studied. Reagents 5/6 aluminum hydroxochloride and sodium aluminate were used during liming. Complex processing of waste generated during reagent water treatment allows to create a low-waste technology for the purification of mineralized water.

adiabatic potential, electronic degeneracy, Jahn-Teller effect, pseudo Jahn-Teller effect, spontaneous symmetry breaking.
Full Text (PDF): Download
Graphical Abstract: This paper discusses the notion of symmetry of polyatomic systems defined as invariance under transformations, and showes that this important property of atomic matter is extremely vulnerable, and may undergo internal breakdown, subject to the presence of electronic degeneracy or pseudodegeneracy. It is shown that electronic degeneracy and its extended form, called pseudodegeneracy, are actually the only source of spontaneous symmetry breaking (SSB) in nature, including all forms of matter, beginning with elementary particles, via nuclei, atoms, molecules, and solids. Theoretically, the vulnerability of the notion of symmetry is due to the fact that, following quantum mechanics, the separation of the motion of electrons and nuclei (and, similarly, the separation of motions of elementary particles) is approximate, and hence the classical notion of polyatomic space configuration is approximate too, with SSB as one of its main violation.
