Synthesis and characterization of porous zinc oxide nano-flakes film in alkaline media
In this study, porous zinc oxide nano-flakes were successfully synthesized by anodization method on zinc substrate in a 0.025 M NaOH and 0.05 M NH4Cl solution with the voltage of 10 V at room temperature. The field emission scanning electron microscopy’s (FESEM) images show the structural evolution during 90 min of the anodization process. They also demonstrate the dependency of growth of ZnO f...
متن کاملEffect of Incorporation of Nano-Hydroxyapatite and Nano-Zinc Oxide in Resin Modified Glass Ionomer Cement on Metal Bracket Debonding
Background and Aim: Use of fluoride releasing materials to decrease the risk of demine-ralization around orthodontic brackets would be reasonable as an adhesive for bracket bonding only if they provide acceptable shear bond strength (SBS). The aim of this study was to evaluate the SBS of resin-modified glass ionomer cements (RMGICs) modified by nano-zinc oxide (NZnO) and nano- hydroxyapatite (N...
متن کاملSynthesis and Characterization of Nano-Sized Hexagonal and Spherical Nanoparticles of Zinc Oxide
ZnO plays an important role in many semiconductors technological aspects. Here, direct precipitation method was employed for the synthesis of nano-sized hexagonal ZnO particles, which is based on chemical reactions between raw materials used in the experiment. ZnO nanoparticles were synthesized by calcinations of the ZnO precursor precipitates at 250 ˚C for 3hours. ...
متن کاملIn Vitro Antibacterial Activity and Minimum Inhibitory Concentration of Zinc Oxide and Nano-particle Zinc oxide Against Pathogenic Strains
In the emerging issue of increased multi-resistant properties in food borne pathogens, zinc oxide (ZnO) and nano-particle zinc oxide (nano-ZnO) are being used increasingly as antimicrobial agents. Thus, the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) of nano-ZnO towards pathogens microbes Bacillus subtilus NRRL B-543, Bacillus megaterium ATCC 25848, Staph...
متن کاملantimicrobial effect of nano-zinc oxide and nano-chitosan particles in dental composite used in orthodontics
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...
