CHARACTERIZATION OF ZINC OXIDE NANOPARTICLES AND THEIR APPLICATIONS IN FOOD SAFETY Ruoyu Li Dr. Mengshi Lin and Dr. Azlin Mustapha, Thesis Supervisors ABSTRACT In this study, ZnO NPs suspension was studied for their antibacterial activities against Escherichia coli O157:H7. Department of Chemistry, Physical Chemistry Laboratory, S. S. J. Timisoara, Romania, 08 - 10 September 2011. SEM images Zinc oxide nanoparticles. In this work, Zinc oxide (ZnO) nanoparticles were used to adsorb H 2 S gas at ambient temperatures. Szalay B, Vezér T. In vitro mutagenicity evaluation of iron oxides nanoparticles by the bacterial reverse mutation assay. Thesis Submitted to the School of Graduate Studies, Universiti Putra Malaysia, in Fulfillment of the Requirements for the Degree of Master of Science . DONYA RAMIMOGHADAM. By . And they found length and average outer diameter of the ZnO nanotubes were about 2.4 m and 200 nm, respec-tively [43]. Co-precipitation method of synthesis and characterization of iron oxide nanoparticles N D Kandpal*, N Sah, R Loshali, R Joshi and J Prasad. Scanning electron microscope was used to decide size, location and shape of the Zinc oxide nanoparticles. Notably, evidence has shown that zinc is an important nutrient in living organisms. The effects of H 2 S concentration (80-1700 mg L-1), nanoparticle size (18, 80-200 nm), gas flow rate (200 and 450 mL min-1), temperature (1-41 C) and adsorbent … Uncoated Zincoxide 42 . In recent years, zinc oxide nanoparticles (ZnO NPs) have gained tremendous attention attributed to their unique properties. February 2014 © of zinc oxide nanoparticle on biodistribution and zinc metabolism in mice over 3 to 35 weeks. 3.4. Zinc oxide: Healthy or risky 43 2.11. Applications of zinc oxide nanoparticles 41 2.9. pared zinc oxide nanotubes by hydrothermal syn-thesis using zinc nitrate as a precursor. Campus Kumaun University, Almora 263601, India . PREPARATION OF ZINC OXIDE NANO- AND MICRO-STRUCTURES USING HYDROTHERMAL-TEMPLATE METHOD AND THEIR APPLICATIONS . Liquid-phase synthesis Laser ablation Pulsed laser ablative deposition (PLD) is a striking synthetic method due to its ability to These images demonstrated that zinc oxide nanoparticles are spherical in shape and their sizes are about 30-63nm. 8 2.10. 13. th. Their results showed minimum toxicity to mice when they were ex-posed to 50 and 500 mg/kg zinc oxide nanoparticle in diet. DKMT Conference on Integrative Medicine, Nutrition and Health. Received 08 February 2013; revised 04 September 2013; accepted 03 December 2013 The zinc oxide nanoparticles (ZnO NPs) green synthesis were prepared by using Olea europaea leaves extract as bio-reductant agent. The development of formulations of nanosized nanoparticles of titanium dioxide and zinc oxide with minimized light scattering in the visible region [27, 28], together with reports on allergic reaction to some organic UV attenuators [29], have resulted in a rapid increase of titania and zinc oxide in sunscreens.
