Structure and photocatalytic influence of N-doping ATO nano-tubes on antibacterial activity toward Escherichia coli

RETRACTED: Effects of N Doping on Structure and Improvement Photocatalytic Properties of Anatase TiO2 Nanoparticles

The Influence of Ag Doping on Structural, Optical Properties and Photocatalytic Activity of TiO2/SiO2 Nanocomposite

In the present study, TiO 2 /SiO 2 and TiO 2 /SiO 2 /Ag nanocomposite powders were synthesized by sol-gel technique. Moreover, for investigation of the Ag doping effect different concentrations of dopant were added. Structures were characterized by IR spectroscopy, Scanning Electron Microscopy (SEM), Energy Dispersive Analytical X-Ray (EDAX), and X-Ray Diffraction (XRD) methods. Fur...

effects of n doping on structure and improvement photocatalytic properties of anatase tio2 nanoparticles

in order to improve uv and visible lights photocatalytic activities of the pure anatase tio2, a novel and efficient n-doped tio2 photocatalyst was prepared by sol-gel method. n-doped titania is prepared using triethylamine (with difference molar ratios) as the nitrogen source. the crystalline structure, morphology, particle size, absorbance and band-gap and chemical structure of n-doped tio2 wa...

antibacterial activity of chitosan against escherichia coli

introduction: chitosan possesses more than 5000 glucossamine residue. since chitosan possesses potentially reactive amino functional groups, this polymer has been shown to be of potential use in many different fields, including as an antifungal compound in agriculture, flocculating in waste water treatment, a food additive and alimentary industries, hydrating agent in cosmetics and more recentl...

Essential Oils Nanoemulsions: ‎Preparation, Characterization and Study of ‎Antibacterial Activity against Escherichia ‎Coli

   This research studies the application of essential oil nanoemulsion as herbal medicine instead of using antibiotics and chemicals. Thyme, shirazi thyme and rosemary essential oils were selected as herbal drugs. Essential oil nanoemulsions with Tween 80 and/or Sodium dodecyl sulfate (SDS) surfactants were prepared and investigated. Physicochemical characterizations such as hydrodynamic di...
