Sonochemical preparation of SnS and SnS nano- and micropowders and their characterization.

Sonochemical production of tin(II) and tin(IV) sulfides is investigated. Different conditions of syntheses are examined: used solvent (ethanol or ethylenediamine), source of tin (SnCl or SnCl), the molar ratio of thioacetamide to the tin source, and time of sonication. The obtained powders are characterized by the X-ray diffraction method (PXRD), scanning electron microscopy (SEM), scanning transmission electron microscopy (STEM), energy-dispersive X-ray spectroscopy (EDX), and the Tauc method.

Application of sonochemically synthesized SnS and SnS in the electro-Fenton process: Kinetics and enhanced decolorization.

SnS and SnS powders were synthesized with the use of ultrasound. The indirect sonication was applied with ultrasound frequency 40 kHz and acoustic power 38 W/L. Products of syntheses were examined with PXRD, TEM, EDX, XPS, and UV-Vis (the Tauc method) investigations.

[Evaluation of the activity of selected elements of the immune system in depression].

Aim: The evaluation of the activity of selected elements of the immune system in depression.

Method: Lymphocyte subsets evaluation (CD3+, CD4+, CD8+, CD16+, CD19+, CD4/CD8) was performed in 32 patients with depression (21 women and 11 men in the age from 21 to 66 years) using the flow cytometry method. The cytokine evaluation (sIL-2R, IL-4, IL-6) was performed in 39 patients with depression (23 women and 16 men in the age from 21 to 66 years) using the ELISA method.
