Facile synthesis of pseudo-peanut shaped hematite iron oxide nano-particles and their promising ethanol and formaldehyde sensing characteristics

Nanobiotechnology emerged as integration of nanotechnology and biotechnology for developing bioactive, biosynthetic and eco -friendly technology for synthesis of nanomaterials. Nanostructures have great demand in areas such as chemistry, catalysis, electronics, energy, and medical applications. Metallic nano-particles are normally synthesized by wet chemical synthesis techniques using the toxic and inflammable chemicals. Present research work on preparation of silver nano-particles by green nano synthesis method and has advantages over conventional methods involving chemical agents which can cause environmental toxicity. The synthesis technique is a cost effective and environment friendly technique for green nano synthesis of silver nano-particles from varying concentrations of AgNO3 solution and extract of Carica papaya fruit of different concentrations which acts as reducing and capping agent. Characterizations has been done using UV–Vis absorption spectroscopy, XRD, particle size analyser and SEM with EDX. Antimicrobial activity was done using Escherichia coli and Pseudomonas.

Zirconia Powders

ABSTRACTNanostructured yttrium stabilized zirconia powders with yttria concentrations between 0.0 and 10.0 mol % were prepared via an aqueous chemical synthesis route. This synthesis involved the spray atomization of the aqueous solution mixture of zirconyl chloride and yttrium chloride into a reaction vessel that contained a diluted ammonium hydroxide, followed by ultrasonication, separation and heat treatment. These powders were characterized using SEM, TEM, XRD, and chemical analysis. The crystalline structure was refined using the Rietveld technique. At temperatures below 200 °C, the powders were amorphous solid solutions with an structure independent of yttria concentration, where yttrium atoms occupied the zirconium positions in the zirconyl group, e.g., (Zr4(1-x) Y4x(OH)8(OH2)16)(8-4x)+. Annealing the sample at 400 °C, the amorphous phases crystallized into monoclinic, tetragonal or cubic nanocrystalline zirconia, depending on yttria concentration, where the non-doped samples had a mixture of monoclinic and tetragonal phases.
