The Solar Army’s mission is to find an alternative fuel source that will replace the burning of fossil fuels. The desired fuel is hydrogen gas, obtained from the reaction of water and sunlight. This reaction happens naturally but needs to be much faster i... see more

Technique for synthesis magnetically operated nanocomposites based on transition metals oxides (MeFe2O4, Me = Fe2+, Ni2+, Co2+) with biologically compatible coating (SiO2)x were developed and optimized. Tetraethoxysilane (TEOS) and sodium silica... see more

The possibility of obtaining cyclopentanone by pyrolysis of calcium adipate at different temperatures was considered. The pyrolysis proceeded with the formation of cyclopentanone and cyclopentene. The use of metal salts and metal oxide cata... see more

A low-temperature hydrothermal synthesis technique was employed as a medium to produce ceria-zirconia mixed oxides particles at temperatures of 200–300 °C and pressure of 10 MPa in a batch process. At these conditions, the average crystallite sizes of cer... see more

A brief review was made, where various views of scientists on role of oxygen in conditions of dissolution of minerals (sulfides, oxides, metals) in a hydrochemical process were discussed, and author’s view on this process was given.

The product information plays an important role in the improvement of the manufacturing, allowing the tracking of the part through the full life cycle. Laser marking is one of the most versatile techniques for this purpose. In this paper, a modification o... see more

In the present paper, porous materials were prepared from the hydrothermal treatment of aqueous solutions of tannin, a renewable phenolic resource extracted from tree barks, containing dissolved salts of transition metals: V, Cr, Ni and Fe. Hydrothermal t... see more

This work studied protective material consisting of several metal oxide composites (Pb3O4, WO3, SnO2, and Bi2O3)-natural rubber (NR) for X-ray and gamma-ray shielding. The composites were prepared through open milling and vulcanization processes and furth... see more

This work aims to study the structural and photocatalytic performance of p-type (NiO) and n-type (SnO2) semiconductor metal oxides via the same synthesis process and conditions. The structural properties of the synthesized nickel oxide and stannic oxide n... see more
