Natural leather still represents great importance among the materials used by humans in modern times, although it is oldest-known fiber humans. Adding new features to leather, such as bacteria and fungi resistance, electrical conductivity magnetic properties, an ambitious goal for developers. In our study, production characterization of anti-microbial sole coated with zinc oxide nanoparticles w...

introduction: ferric sulfate pulpotomy is a safe and effective method of the pulpotomy of primary teeth. but the results of different studies indicate low success rate of ferric sulfate pulpotomy in comparison to formocresol pulpotomy and a portion of these failures may be related to stimulating and harmful effects of zinc oxide eugenol paste. the aim of this study was to determine and compare ...

Zinc oxide (ZnO) nanoparticles are being increasingly utilized in a variety of products and applications and are therefore commonly discharged into aquatic environments, increasing exposure and potentially impacting aquatic organisms. Zinc oxide nanoparticles can depress growth of some marine phytoplankton, and several examples of nanoparticle trophic transfer have been documented, although not...
