https://doi.org/10.53293/jasn.2022.5179.1178

Abstract
  Extensive studies were devoted to iron oxide nanoparticles (IONPs), in recent years. Iron oxides are chemical compounds that have various polymorphic forms, including maghemite (γ-Fe2O3), magnetite (Fe3O4), and Hematite (α-Fe2O3). Among them, the most important studied is magnetite (Fe3O4) ...  Read More ...

Volume 2, Issue 3 , September 2022, , Page 147-156

https://doi.org/10.53293/jasn.2022.4558.1125

Abstract
  In this study, Au:TiO2 nanoparticles (NPs) are prepared by using the laser ablation method in liquid at different laser energies (600, 800, and1000 mJ). After that, Au: TiO2 NPs were deposited on porous-Si(PS). Porous silicon (PS) is synthesized by using the photo-electrochemical etching (PECE) of n-type ...  Read More ...
