Abstract
  Zinc Oxide (ZnO) nanoparticles (NPs) were biosynthesized by using a leaf extract of Allium Calocephalum Wendelbow (ACW) plant. The impact of various zinc salts on the characteristic properties of synthesized ZnO NPs and which salt is more suitable for the synthesis of ZnO NPs were investigated. The used ...  Read More

Abstract
  Supernova remnants (SNRs) are remarkable astronomical objects which are a diffuse, expanding nebula of gas that is a direct result of a star's explosive death, resulting in a supernova explosion. SNRs play a vital role in the scattering of tough elements which are made in the supernova explosion into ...  Read More

Abstract
  This study examines the synthesis of copper oxide nanoparticles (NPs) by using a Q-Switched Nd-Yag (1064 nm) laser on copper foil immersed in Distilled Water (DW). The solution color changed to light green refers to the production of copper oxide NPs. The generated nanoparticles were studied to determine ...  Read More
