Spectroscopic Investigation and Magnetic Study of Iron, Manganese, Copper and Cobalt-doped Hydroxyapatite Nanopowders

H. Kamal & A. M. Hezma · Physical Science International Journal · 2015

Pure, Mn+2, and Fe+3- doped hydroxyapatite (HAp) nanoparticles were synthesized by the wet chemical method. Another two samples were prepared by mixing Mn+2 with Cu+2 into HAp (Mn-Cu HAp) and Fe+3 with Co+2 into HAp (Fe-Co HAp). All samples were prepared without change in the sto...

Structural Investigations on Na2O – CaO-V2O5- SiO2 Bioglass Ceramics

G. El-Damrawi, A. K. Hassan, H. Kamal, M. Aboelez & S. Labeeb · Current Journal of Applied Science and Technology · 2016

All as obtained glasses in the system 24.5 Na2O-24.5 CaO-6 P2O5- xV2O5 (45-x) SiO2 (x ranges from 0-15 mole %) are transparent and have an amorphous network structure. Glasses containing up to 6 mol% V2O5 still transparent upon heat treatment at 660°C for 4 hours. On the other ha...
