Pure ZnO and Sr doped ZnO nanoparticles are synthesized via Co-precipitation method using Zinc acetate dehydrate Zn (CH3COO)2. 2H2O, Strontium acetate Sr (CH3COO)2, as source materials. The influence of Sr dopants contents on the morphology, absorption, emission, and photocatalytic activity of ZnO synthesized nanoparticles was investigated systematically. The photocatalytic activity of pure and...

The effect of Zn-doping in CoFe2O4 nanoparticles (NPs) through chemical co-precipitation route was investigated in term of structural, optical, and magnetic properties. Both XRD and FTIR analyses confirm the formation of cubic spinel phase, where the crystallite size changes with Zn content from 46 to 77 nm. The Scherrer method, Williamson-Hall (W-H) analysis, and size-strain plot method (SSPM)...

The possibility of obtaining nanocrystaline lead sulfide by an electrolytic method using electrodes is demonstrated, and the influence temperature on synthesis process investigated. Based results X-ray diffraction studies, chemical phase composition obtained samples determined, as well parameters unit cell crystals lattice. size nanocrystallites magnitude residual mechanical strain in them dete...

Although embedded Ge nanocrystals (NCs) have been grown by variety of techniques and its properties have been studied extensively, intrinsic properties of isolated Ge NCs have not been studied properly due to lack of proper synthesis technique. Here we report on the synthesis of freestanding Ge nanoparticles (NPs) down to approximately 7 nm using ball milling technique and study its structural ...

In this study, an abundant and eco-friendly photocatalytic material, Fe2O3 particles were synthesized by sonochemical method. Morphological microstructural investigations of undoped Ni, Co-doped performed. The effect particle morphology microstructure on its performance was further investigated. Comparative studies for evaluating crystallite sizes conducted Williamson-Hall (W-H) method modified...

Distribution data describing the current shea range were obtained from John Hall (University of Wales, Bangor); for details, see previous reports and Vitellaria paradoxa: a monograph (Hall et al., 1996). In 2010, these records were supplemented with shea plot data from Burkina Faso, Mali and Ghana, and with the collection localities of herbarium specimens held at the Royal Botanic Gardens, Kew ...

Pristine Antimony tungstate nanoparticles prepared via a simple hydrothermal process showcase interesting photocatalytic efficiency, degrading Methylene Blue (MB) completely in 180 min under visible light. In this study, the impact on crystalline quality and related optical properties as well efficiency of antimony due to temperature variation during synthesis are explored. While X-ray diffract...
