This research was conducted to evaluate effects of mycorrhiza fungi and nano zinc oxide on agro physiological traits of wheat under salinity stress based on factorial experiment according complete randomized block design with three replications under greenhouse condition at 2014. Treatments included salinity in three levels [no-salt (S0) or control, salinity 40 (S1) and 80 (S2) mM NaCl], two le...

introduction: intrinsic tooth discolorations after endodontic treatment are principally attributed to the composition of necrotic pulp tissue, hemorrhage within the pulp cavity, endodontic medicaments and/or filling materials. residual sealer left in pulp chamber after obturation can cause discoloration. the objective of this in vitro study was to evaluate coronal discoloration created by ah26 ...

background & objectives: direct addition of antimicrobial materials to food during food processing is an effective method for controlling microbial contaminants of food and extending the shelf-life of food products. objective of this research was to study the antimicrobial effect of zinc oxide (zno) nanoparticle and potential applications of zno nanoparticles in terms of controling two food...

background: new treatment modalities are developed with the aim of escalating tumor absorbed dose and simultaneously sparing the normal structures. the use of nanotechnology in cancer treatment offers some possibilities including destroying cancer tumors with minimal damage to healthy tissues. zinc oxide nanoparticles (zno nps) are wide band gap semiconductors and seem to have a good effect on ...

   Zinc oxide has been considered as a promising semiconductor material for fabrication of transparent conductive oxides (TCOs), electronic devices, optoelectronics, and solar cells. Among the various morphologies of zinc oxide, nanorods are more widely used because of the ease of synthesis and providing a direct path for the transport of charge carriers. The electrochemical deposi...

BACKGROUND Antibiotic resistant bacteria can be considered as a main problem in infection management. Zinc oxide nanoparticles (ZnO NPs), individually or in combination with antibiotics, can be considered as good candidates for struggling against drug resistant bacteria. METHODS In this study, Zinc oxide nanoparticles were synthesized using sol-gel method in low temperature as a cost effectiv...

background: galvanization is the process of coating steel or cast iron pieces with a thin layer of zinc allowing protection against corrosion. one of the important hazards in this industry is exposure to zinc compounds specially zinc oxide fumes and dusts. in this study we evaluated chronic effects of zinc oxide on the respiratory tract of galvanizers. method : 188 workers were selected from a ...

the improvement of the physical properties of indium tin oxide (ito) layers is quite advantageous in photovoltaic applications. in this study the ito film is deposited by rf sputtering onto p-type crystalline silicon (c-si) with (100) orientation, multicrystalline silicon (mc-si), and glass substrates coated with zno and annealed in vacuum furnace at 400°c. electrical, optical, structural and m...
