    • Enhancement of the critical current density in FeO-coated MgB2 thin films at high magnetic fields 

      Surdu, Andrei E.; Hamdeh, Hussein H.; Al-Omari, Imaddin A.; Sellmyer, David J.; Socrovisciuc, Alexei V.; Prepelita, Andrei A.; Koparan, Ezgi T.; Yanmaz, Ekrem; Ryazanov, Valery V.; Hahn, Horst; Sidorenko, Anatolie S. (BEILSTEIN-INSTITUT, 2011-12-14)
      The effect of depositing FeO nanoparticles with a diameter of 10 nm onto the surface of MgB2 thin films on the critical current density was studied in comparison with the case of uncoated MgB2 thin films. We calculated the ...
    • Fischer-Tropsch synthesis: Effect of Cu, Mn and Zn addition on activity and product selectivity of cobalt ferrite 

      Gnanamani, Muthu Kumaran; Hamdeh, Hussein H.; Jacobs, Gary; Qian, Dali; Liu, Fang; Hopps, Shelley D.; Thomas, Gerald A.; Shafer, Wilson D.; Xiao, Qunfeng; Hu, Yongfeng; Davis, Burtron H. (Royal Society of Chemistry, 2016)
      The effect of Cu, Mn and Zn addition on cobalt ferrite was investigated for Fischer-Tropsch synthesis (FTS). Oxalate co-precipitation followed by decomposition under inert conditions was used to obtain various metal ...
    • Mossbauer investigations in hematite nanoparticles 

      Al-Omari, Imaddin A.; Narayanaswamy, Venkatesha; Halder, Sajib; Hamdeh, Hussein H.; Alaabed, Sulaiman; Kamzin, Aleksandr. S.; Muralee Gopi, Chandu V.V.; Khaleel, Abbas A.; Issa, Bashar; Obaidat, Ihab M. (AMG Transcend Association, 2021-10-16)
      Hematite nanoparticles of average size 20 nm were synthesized using the sol-gel method, and the structural characterizations were conducted using XRD and TEM. The XRD profile revealed a small fraction of the maghemite ...
    • Role of Cu2+ substitution on the structural and magnetic properties of Ni-ferrite nanoparticles synthesized by the microwave-combustion method 

      Elshahawy, A. M.; Mahmoud, Mohamed H.; Makhlouf, Salah A.; Hamdeh, Hussein H. (Elsevier B.V., 2015-11)
      Ni1-xCuxFe2O4 (x=0.00, 0.05, 0.10, 0.15, 0.20 and 0.25) nanoparticles were successfully synthesized by microwave-induced combustion process using urea as fuel. The structural and magnetic properties of the samples were ...
