Graphical Abstract: As a result of the comparative study of axial ligand orientation towards the equatorial plane in α - dioximates Co (III) obtained by us and those described in the specialized literature (found in Cambridge Crystallographic Data Centre) showed that the external anions and solvent molecules contribute to the orientation of axial ligands as selenourea and thiourea. For aniline and sulphanilamide ligands, is more convenient the parallel orientation to form π-π interactions between the aromatic rings of ligands and the metallocycle of equatorial plane.

Graphical Abstract: Macrophages play an important role in the pathological development of different diseases. Therefore, macrophage targeting represents an important challenge in design of new medicines. This review gives a general presentation of small molecule-recognition concepts used for macrophage targeting. It describes mechanisms and systems for macrophage-targeted delivery, their obtaining and application.

Graphical Abstract: Iron-based nanoparticles have gained a lot of attention due to their properties which offer a broad range of biomedical and industrial applications. Traditional methods of synthesis of iron nanoparticles strongly influence their properties and limit their applicability. Recently, there has been a growing interest in the development of biological routes of syntheses of iron nanoparticles as the resulting particles have structural characteristics required by biomedical field. The mechanism for the synthesis of iron-based nanoparticles by microorganisms and its current limitation are presented.

Graphical Abstract:
In Memory of Valeriu Ropot for his scientific contributions in Waters Protection
The present study estimates chemical composition and status of the groundwater from the Dniester river basin. Research includes defining of springs/fountains location, evaluating physicochemical features of water, highlighting of main pollutants and pollution sources, establishing of water type and quality. The research was achieved within the State Program "Scientific research and water quality management".

Graphical Abstract: The key quantitative characteristics of the theory of buffer action for polycomponent mono- and two-phase systems have been derived. It is shown, that the buffer properties in relation to the solid phase components are amplified with an increase of solubility due to protolytic or complex formation equilibria in saturated solutions.

Graphical Abstract: Crystalline precipitate which occurs due to the presence of tartaric salts is frequently encountered in young wines in form of white-dirty lamellar crystals at the bottom of tank. The aim of the study is to prevent the tartaric salts from crystallization in young wine blend Biance/Sauvignon by implementing various schemes and procedures.
