The present study was carried out to determine whether low dose of zinc oxide nanoparticles (Nano-ZnO) could serve as a potential substitute of pharmacological dose of traditional ZnO in weaned piglets. 180 crossbred weaning piglets were randomly assigned to 3 treatments. Experimental animals were fed basal diet supplemented with 0 mg Zn/kg (Control), 600 mg Zn/kg (Nano-ZnO) and 2000 mg Zn/kg (...

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...

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. the p...

In order to provide ultraviolet barrier, antifungal and antibacterial properties, nano-zinc oxide (ZnO) was added lamellar zirconium phosphate (ZrP). The synthesized via reaction of oxychloride octahydrate phosphoric acid following its chemical modification with Jeffamine nano-ZnO. Diffractometric, morphological, thermal, structural relaxometric evaluations were conducted. Fourier transform inf...

For a full estimation of the risk related with the presence of engineered nanoparticles (ENPs) in the environment, the use of the current ecotoxicological methods may prove insufficient. In the study presented herein, various methods of assessment of ecotoxicity were applied to compare the phytotoxicity of three ENPs: nano-ZnO, nano-TiO2 and nano-Ni. The toxicity was assayed both for aqueous so...

ZnO nanoparticles have been proved to be promising in cancer treatment, including the tumor cells destruction with minimal damage to the healthy cells. In the present study highly pure ZnO nano particles with a narrow size distribution of 16-19 nm were prepared by the simple DMC (Dry Mechano-Chemical) method in the lab. The anticancer activity on MCF7 (Breast cancer cell) and A549 (Lung Cancer ...

zno nanorod was prepared by microwave assisted method. the crystal structure of the nano powders were confirmed by x-ray diffraction analysis and the mean particle size was estimated by the scherrer,s formula .the surface morphology of the nano particles were analyzed by   using sem . the absorption spectrum of the material in the uv-vis range was recorded .the energy band gap of the material w...

Si, Xe and C NMR is used to investigate a porous material consisting of nano-sized ZnO particles coated by silane molecules. These materials are synthesized by a novel sol–gel procedure where the nanoscale ZnO particles are formed in the presence of the coating material 3-methacryloxypropyl-trimethoxysilane (‘‘silane’’). The BET specific surface of the uncoated particles, synthesized by the sam...

Minimally processed pomegranate rapidly loses its overall quality because of high water loss and microbial contamination. Nano-ZnO in combination with carboxymethyl cellulose (CMC) coating was used on pomegranate arils. Arils were dipped for 4min in distilled water (control), 0.1 or 0.2% (w/v) nano-ZnO suspension and then ZnO treated arils were coated with 0.5% (w/v) CMC and stored for 12days a...

The influence of different application methods on UV protective properties of white and dyed cotton functionalized with ZnO nanoparticles (nano-ZnO) was investigated. The methods differ in application procedure, time of treatment and auxiliaries used in the treating bath. The ultraviolet protection factor (UPF) was determined for untreated and functionalized samples. The presence of nano-ZnO on...
