Today, the antiviral activity of oxide nanomaterials can be used in fight against viral disease COVID-19. It is thought that Ag nanoparticles may bind to surface glycoprotein virus and interfere with virus’s interaction epithelial cells, inhibit reproduction by releasing silver ions cell. The viruses’ inhibition RNA (ribonucleic acid) DNA (deoxyribonucleic genomes nanocomposites action was pres...

H2 production can be used as a clean and renewable energy source for various applications, including fuel cells, internal combustion engines, chemical production. Using nickel-based catalysts steam reforming biomass tar presents challenges related to catalyst deactivation, poisoning, heterogeneous composition, high process temperatures, gas impurities. To overcome these challenges, adopting wit...
