Zeolites have become promising adsorbents for wastewater treatment due to their enhanced adsorption capacity, stability of crystalline structure, high porosity and surface area. One of the primary goals of our study was to assess the effectiveness of employing NaY zeolite as a sorbent and potential solid matrix for immobilizing radionuclides. In th...

In this work we studied the interaction of the sea urchin skeleton with polyethylsilsesquioxane to obtain composites and studied their properties. The composite was obtained by interaction of polyethylsilsesquioxane with the skeleton of a sea urchin at a ratio of 2:1 under the conditions of mechanochemical activation. When the composite is heated,...

The photocatalytic properties of heterostructures comprised of various strontium bismuthates and bismuthyl carbonate were studied. Enhanced photocatalytic activity was found in SrxBiyOz/(BiO)2CO3 heterostructures for various strontium bismuthates. The enhanced photocatalytic activity in this type of heterostructure was found to arise from type II h...

In this work, we obtained polycalciumphenylsiloxane (PCPS) by the interaction of calcium bis (acetylacetonate) with polyphenylsiloxane. The first method consisted in boiling the starting reagents in toluene for several hours; the second was as follows: the mixture of the starting reagents was preliminarily treated mechanically in a ball mill, follo...

The paper presents spark plasma sintering-reaction synthesis (SPS-RS) of SrTiO3-based mineral-like ceramics with a perovskite structure, which is promising for immobilization of Sr-90 radionuclides. Detailed time-resolved study of phase transformations taking place in the reactive mixture (SrCO3 and TiO2) within 20–1000 °C temperature range was con...

The morphology, specific surface area, and sorption properties toward Sr-90 radionuclides in seawater of a sorption material based on manganese oxide have been investigated. The material was fabricated through interaction of KMnO4 and H2O2 with subsequent annealing at 500 °C. The sorbent is characterized with the mechanical strength sufficient for...

Polyphenyl siloxanes containing chromium, iron, and aluminum in the backbone chain have been synthesized. The structure of the obtained staircase nano-metal complexes has been studied by the methods of XRD analysis and IR, ²⁹Si and ²⁷Al NMR, and XPS spectroscopy and scanning electron microscopy. Physical-chemical characteristics of these compounds...

The study of the structure of polylphenylsiloxanes containing magnesium, cobalt, nickel, and zinc has been performed by the methods of PAS, XRD, and XPS. Using the XRD data, the areas of cross-section of polymer molecules (according to the Miller–Boyer method) and coherent scattering (CS) volumes have been calculated. The data of positron annihilat...

... Fruitful study of the chemistry of polyorganosiloxanes, polymetallorganosiloxanes and their derivatives expands the scope of application of these compounds. Thus, they can be used to produce surfactants, synthetic rubbers [2], various composites [3], biomimetic materials [4], additives to machine oils [5,6], membranes, films, etc. ...
... Second, it represents a matrix (template) for the formation of a porous inorganic skeleton in the composite. A similar solution has already been successfully implemented by the authors of the present study, earlier in [48,49], where biomimetic composites were synthesized. In the present study, a simpler method of reaction, according to Equation (1), implemented under microwave hydrothermal heating conditions, was chosen. ...
... Using the spark plasma sintering (SPS) consolidation method, we were able to immobilize adsorbed cobalt ions quickly and efficiently into a strong ceramic wollastonite matrix. SPS is carried out by applying a pulsed direct current through the powder mass simultaneously with mechanical action, generating localized joule heating and spark discharges at the interface between particles [42,43]. This process leads to rapid heating and enables sintering to occur at lower temperatures and for shorter periods of time than conventional methods. ...
... It is shown that there is a direct relationship between the thickness of the surface layer of spherical particles of PMOS and the size of spherulites, which indicates the fractal structure of larger particles [11]. ...
... Today, to establish the structure of polymetallorganosiloxanes, such a probe method as PAS [9,10] can be used to determine defects in the structure of matter, the number of elementary units per unit volume [11,12], the environment of atoms and "holes" of free volume, based on the values of annihilation numbers [13], as well as diffractometry. In this paper, we have used both methods in connection with each other. ...
... These data coincide with the percentage of T2 (60%) and T3 (40%) fragments. Based on the data obtained, the spatial layered structure of polyphenylsiloxanes containing bivalent and trivalent metals was presented [10]. ...
