In order to investigate the effect of salinity tension and zinc nano oxide on physiological parameters of Rapeseed and Camelina, a factorial experiment was conducted based on a completely randomized design with three replications in the greenhouse conditions of Department of Biology of Urmia University in 2012-13. The factor of zinc nano oxide was investigated at three levels of zero, 25 and 1...
INTRODUCTION: Antibacterial properties of nanoparticles have recently come into the spotlight in endodontic therapy. OBJECTIVES: Evaluation of the antimicrobial efficacy of zinc oxide based sealer incorporated with silver and zinc oxide nanoparticles compared with simple zinc oxide sealer against Enterococcus faecalis. MATERIALS AND METHODS: The study was conducted on 60 human extracted mandibu...
background : incidence of white spots due to demineralization of enamel and gingival problems is an unacceptable result of orthodontic treatment. plaque accumulation and bacterial biofilm growth are responsible for these phenomena. the resin-based dental composites used as bonding agents in orthodontics play a major role in mentioned problems. as recent researches assert the an...
Metal-oxide (MO) semiconductors have emerged as enabling materials for next generation thin-film electronics owing to their high carrier mobilities, even in the amorphous state, large-area uniformity, low cost, and optical transparency, which are applicable to flat-panel displays, flexible circuitry, and photovoltaic cells. Impressive progress in solution-processed MO electronics has been achie...
Quantum dot (QD), also called artificial atom, is a semiconductor nanocrystal with the size on the order of a few nanometers. By modifying its composition, size and shape, its density of electronic states can be engineered and thus many physical properties can be widely and easily adjusted. Strong quantum confinement of electronic carriers at nanometer scale makes band-gap and luminescence ener...
BACKGROUND: Suitable and useful usage of different kind of fertilizers is the main way for reformation and potential of soil fertility and increasing of crops yield. Microelements are the critical elements for plants; also play the important role in crop productivity where it is used in low rate. Optimum plant nutrition and maximum yield is achieved when nutrient elements are a...
