Given the non-renewability of fossil fuels, the task of processing plastic waste into liquid fuels seems to be a promising one. Thermocatalytic conversion is one of the methods that allows obtaining liquid products of the required hydrocarbon range. Clays and clay minerals can be distinguished among possible environmentally friendly, cheap, and common catalysts. The moderate acidity and the presence of both Lewis and Brønsted acid sites on the surface of clays favor heavier hydrocarbons in liquid products of reactions occurring in their pores. Liquids produced with the use of clays are often reported as being in the gasoline and diesel range. In this review, the comprehensive information on the thermocatalytic conversion of plastics over clays obtained during the last two decades was summarized. The main experimental parameters for catalytic conversion of plastics according to the articles’ analysis, were the reaction temperature, the acidity of modified catalysts, and the catalyst-to-plastic ratio. The best clay catalysts observed were the following: bentonite/spent fluid cracking catalyst for high-density polyethylene (HDPE); acid-restructured montmorillonite for mediumdensity polyethylene (MDPE); neat kaolin powder for low-density polyethylene (LDPE); Ni/acidwashed bentonite clay for polypropylene (PP); neat kaolin for polystyrene (PS); Fe-restructured natural clay for a mixture of polyethylene, PP, PS, polyvinyl chloride (PVC), and polyethylene terephthalate (PET). The main problem in using natural clays and clay minerals as catalysts is their heterogeneous composition, which can vary even within the same deposit. The serpentine group is of interest in studying its catalytic properties as fairly common clay minerals.

All data were obtained using atomic force microscopy. The spring constant of probes was specified for each sample measurement.

The surface of immature reticulocytes was examined by atomic force microscopy (AFM) to determine specific changes during the development of ALL and AML. In patients with ALL the surface area of reticulocytes increased by 18.5 %, volume by 8.7 %, the width of invaginations by 18 %, and cell height decreased by 7.8 %. In patients with AML, the volume increased by 12.6 %, roughness by 35.5 %, the height of protrusions by 36.2 %, the depth of invaginations by 24.8 %, their width by 18.2 %, and the maximum height difference of the surface by 31.9 %. The obtained data1 has important prognostic value in studying the bone marrow activity during acute leukemia.

The lack of studies of some rare earth elements (REE) and the insufficient knowledge of their catalytic activity in the structure of LDHs indicate the need for further research.

It is known that mitochondria are involved in many cellular activities like lipid modifications, redox balance, calcium balance and cell death. Many important functions of mitochondria change in cancer, and these organelles can be a target of therapy. The aim of the research was to study the effect of SMF on cancer cells.

No significant differences in Young's modulus were found, but a downward trend was noted. The obtained data has important prognostic value in studying the bone marrow activity during acute leukemia.

The objective of the work is an investigation of erythropoiesis cytokinetic parameters under the normal health conditions and during the development of the acute lymphoblastic leukemia and the acute myeloblastic leukemia. It was found that the distribution of reticulocytes shifts towards an increase of immature reticulocyte fraction while the ratio between maturing and immature cells remains unchanged. The method presented can be used in clinical diagnostic and scientific research of bone marrow hematopoietic activity.
