The techniques of melt-quenching have been used to generate 53B2O3—2NaF—27PbO – $$(20-x)$$ BaO— $$x$$ La2O3 $$(0\le x \ge 15) glass system$$ . XRD patterns established the amorphous character samples. There is a clear evidence role modifier in network. thermal characteristics identified increase with an content. Increasing increases linear and non-linear optical bandgap energy Urbach energy. By...

In this paper, La2O3-B2O3-CaO (LBC) glass ceramics were sintered at low temperature to density BaTi4O9 (BT4) microwave dielectric ceramics. The effects of composition ratio and sintering on the micromorphology, phase properties LBC/BT4 multiphase investigated. Experimental results showed that LBC microcrystalline BT4 happened between ceramic interface reaction obviously, with increase content i...

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...
