Abstract: This research work discusses the biosynthesis of zinc oxide nanoparticles using Aloe vera leaves extract. This green method of nanoparticle synthesis is advantageous because it is cost effective and has no negative environmental impact. This synthesis was carried out in solution and the formation of the Zinc oxide nanoparticles was observed by colour change. The FTIR spectrum of the nanoparticles showed sharp bands at about 435 cm-1 and 491 cm-1 which can be attributed to ZnO stretching bands. The band at 1313 cm-1 corresponds to C-N stretching bonds of......

Abstract: 2-amino thiazole was diazotized with sodium nitrite and 6(M) hydrochloric acid at 00C. Then it was coupled with 2-methoxy aniline. The mixture was stirred for 1h then 0.001(M) sodium hydroxide solution was added into the mixture until PH=6.0 was reached. Ruthenium (II) complex was prepared by adding the above dye to the hot solution of [Ru(bpy)2cl2]in ethanol and refluxed for 2h. After removal of excess solvent under reduced pressure, ammonium hexafluoro.......
