Increased production and use of zinc oxide nanoparticles (ZnO-NPs) in consumer products has prompted the scientific community to investigate their potential toxicity, and understand their impact on the environment and organisms. Molecular mechanisms involved in ZnO-NP toxicity are still under debate and focus essentially on high dose expositions. In our study, we chose to evaluate the effect of...

Nanoparticles are being intensively investigated because of their unique optical, electrical and catalytic properties which make them a potential material for utilization in the field of medicine electronic and environmental issues. This paper is concerned with the removing a heavy metal, Chromium, from its aqueous solution by Iron oxide nanoparticle filtration. Solutions of varying chromium co...

objective: zinc oxide eugenol (zoe) under composite restorations should be covered with a suitable material in order to prevent the harmful effect of zoe on the composite. the aim of this in vitro study was to evaluate microleakage of composite restorations in pulpotomized primary molars with different bases for covering the zoe layer and to assess the distance between different layers. materia...

a novel zinc oxide - agar nanocomposite was successfully synthesized using zinc chloride as a precursor. the nanocomposite was prepared using a domestic microwave oven. the prepared nanocomposites have been characterized by fourier transform infrared (ftir) spectroscopy, x-ray diffraction (xrd) analysis, scanning electron microscopy (sem) and uv- visible spectroscopy. the crystalline properties...
