Department of Physics National Institute of Technology, Rourkela Rourkela-769008, Orissa, India CERTIFICATE This is to certify that, the work in the report entitled “Synthesis and Characterization of Zinc Oxide Nanoparticles by Sol-Gel Process” by Mr Surya Prakash Ghosh, in partial fulfilment of Master of Science degree in PHYSICS at the National Institute of Technology, Here we get a new line of high purity zinc oxide nanoparticles primarily targeted for antimicrobial activity against Bacillus subtilis and Escherichia coli.as shown in figure 1.Zinc oxide nanoparticles prepared Nanoparticles manufactured by different methods were found to be broadly similar, and most of their properties apart from size distribution match those of larger particles. Department of Chemistry, Physical Chemistry Laboratory, S. S. J. Zinc oxide nanoparticles and curcumin have been shown to be excellent antimicrobial agents and promising anticancer agents, both on their own as well as in combination. EXPERIMENTS ZnO nanoparticles fabricated via hydrothermal route from urea solution and zinc chloride solution. Green synthesis of zinc oxide nanoparticles using fresh peels extract of Punica granatum and its antimicrobial activities. Zinc Oxide ( ZnO )Zinc Oxide ( ZnO ) WAQI AHMED NAJAMWAQI AHMED NAJAM 31159991183115999118 Master Of Electronics And InformationMaster Of Electronics And Information Engineering (MEIE)Engineering (MEIE) Email:Email: … Zinc oxide nanoparticles (ZnO NPs) are of particular interest for antimicrobial applications as, unlike many other types of NPs, ZnO is an FDA approved food additive and is generally recognised as safe and non-toxic in low concentrations. Zinc Oxide (ZnO) is one of the most exploitable nanoparticles (NPs) in industrial and consumer products especially in cosmetics, food additives, pharmaceuticals, biosensors, photo electricity and rubber industry etc.Regarding their wide variety of applications, they constantly come into contact with human body parts. 7-9. To determine particle size distribution, 30 w% zinc oxide dispersions were prepared by adding zinc oxide to a mixture of water and dispersing agent. Antibacterial activity of zinc oxide nanoparticles (ZnO-NPs) has received significant interest worldwide particularly by the implementation of nanotechnology to synthesize particles in the nanometer region. antibacterial activity of zinc oxide nano particles were probed by many researchers. nanoparticles /crystals in the calcinated zinc oxide, ZnO than in the uncalcin ated zinc oxide. Trophic transfer of differently coated zinc oxide nanoparticles using crustaceans (Daphnia magna) and zebrafish (Danio rerio) Zinc oxide (ZnO) nanoparticles had been in current studies due to its large bandwidth and high exciton binding energy and it has prospective applications such as electronic, optical, mechanical, magnetic and chemical properties that are significantly different from those of bulk counterpart. Sol-Gel Synthesis of Zinc Oxide (ZnO) Nanoparticles … 285 bandgap energy of 3.49 ev for as-prepared samples. Relative Density : 5.607 Melting Point : Zinc oxide sublimes at atmospheric pressure at temperatures over 1200 oC. Under high pressure a melting point of 1975 C has been estimated. Zinc oxide nanoparticles are the semiconductor materials having band gap energy 3.37 eV and very large excitation binding energy (60meV) at room temperature.
