LiV(PO) cathodes for Li-ion batteries (LIBs) were synthesized using a hydrothermal method with the subsequent annealing in an argon atmosphere to achieve optimal properties. The X-ray diffraction analysis confirmed the material's single-phase nature, while the scanning electron microscopy revealed a granular structure, indicating a uniform particle size distribution, beneficial for electrochemical performance. Magnetometry and electron spin resonance studies were conducted to investigate the magnetic properties, confirming the presence of the relatively low concentration and highly uniform distribution of tetravalent vanadium ions (V), which indicated low lithium deficiency values in the original structure and a high degree of magnetic homogeneity in the sample, an essential factor for consistent electrochemical behavior.

1-D oxides Zn1-xCuxO and spherical composites Zn1-xCuxO/CuO were obtained by thermolysis of formate-glycolate complexes Zn1-xCux (HCOO)(OCH2CH2O)1/2 (0 ≤ x ≤ 0.15). The structural and property characteristics showed that Cu was introduced into the Zn site of the ZnO lattice to form the Zn0.

The ESEEM spectroscopy was used to determine positions of the Nd impurity ions in YSiO single crystal. It is established that neodymium ions substitute yttrium ions in the Y2 positions with seven nearest oxygen ions. Crystal field parameters of Nd impurity centers in isotopically pure YSiO and ScSiO single crystals were determined using data of CW EPR spectroscopy and the known energy level schemes.

Ninety six colorectal carcinoma patients were included in a randomised study, 48 were treated with Ukrain monotherapy (15 with metastatic and 33 with nonmetastatic colorectal carcinoma) and 48 with 5-fluorouracil (5-FU) and X-ray therapy (the same randomised groups). The results of therapy including clinical, haematological, immunological and biochemical parameters show that Ukrain has favourable properties in the treatment of colon and rectal cancer as a monotherapy because of its malignotoxic and immunomodulating action. Objective response rate in the group of metastatic colorectal cancer treated by Ukrain was 40%.
