Natural minerals are widely used in treatment technologies as mineral fertilizer, food additive in animal husbandry, and cosmetics because they combine valuable ion-exchanging and adsorption properties together with unique physicochemical and medical properties. Saponite (saponite clay) of the Ukrainian Podillya refers to the class of bentonites, a subclass of layered magnesium silicate montmor...

Deep-ultraviolet (deep-UV) nonlinear optical (NLO) crystals play a crucial role in modern laser frequency conversion technology. Traditionally, the exploration of deep-UV NLO crystals is mainly focused on borates, while, the use of phosphates recently opened up a novel and promising non-boron pathway for designing new deep-UV NLO crystals. Extending this pathway to aluminosilicates led to the d...

Abstract The paper presents the results of studies effect electromagnetic, ultrasonic and acid treatments on structure adsorption index alkaline-earth bentonite modified with nanoparticles silicon oxide aluminum. Studies have shown that contribute to an increase in capacity by 5, 10, 25%, respectively. Modification stabilized nanodispersed hydrosols amorphous (6-10.5 nm) crystalline boehmite (3...

The current focus on renewable energy sources and the circular economy favors thermal conversion of low-quality fuels, such as biomass waste. However, main limitation their usability in power sector is risk slagging, fouling, ash deposition, high-temperature corrosion. These problems may be avoided or significantly mitigated by application aluminosilicate clay minerals fuel additives. In this p...

The decoration of a togatus Roman sculpture found in Salamanca 2015 has been examined to identify the applied pigments. study was performed using environmental scanning electron microscopy –ESEM– with an energy-dispersive X-ray analyser –ESEM-EDX– and Raman spectroscopy –RS– microscopic mode. ESEM-EDX allowed elemental chemical composition samples be established, concentration distribution each...

Alkali-activated concrete (AAC) is widely considered to be a sustainable alternative Portland cement concrete. However, on account of extensive heterogeneity in composition the aluminosilicates, coupled with failure classical materials science approaches unravel underlying composition-property linkages, reliable prediction AAC's properties has remained infeasible. This paper presents random for...

The paper presents results of studies on the possibility using ultrafiltration method supported by sorption low-cost, easily accessible aluminosilicates to purify water contaminated with radionuclides. An aqueous solution radionuclides in form cations at different oxidation states—Cs(I)-137, Co(II)-60 and Am(III)-241—as well as pertechnetate anions—TcO4?-99m—was treated proposed hybrid method. ...
