This study successfully incorporated different chromium ions (Cr3+) fractions into beta-tricalcium phosphate (beta TCP) using the wet-precipitation process aided by microwave radiation. The microstructure analysis of the prepared materials was investigated using XRD and FESEM. The XRD results revealed that the characteristic peaks of Cr-beta TCP materials matched the standard phase of beta TCP crystals. The lattice parameters were decreased with increasing amounts of Cr3+ ions while the degree of crystallinity was increased. The FESEM results revealed that the entire materials were spherical from nano to micro size. The particle growth rate increased significantly as the amount of Cr3+ ions increased. SBF solution was used to test the bioactivity of materials for 14 days at 37 degrees C. The results shows that incorporating Cr3+ ions accelerated the degradation rate of beta TCP and enhanced the deposition rate of the apatite layer. The antibacterial study of beta TCP doped with Cr3+ ions confirmed that the samples were effective as antibacterial agents against Pseudomonas aeruginosa (P. aeruginosa).

LANTHANUM DOPED DICALCIUM PHOSPHATE MIXED WITH GRAPHENE OXIDE BONE CEMENTS AS A POTENTIAL MATERIAL IN BIOMEDICAL APPLICATIONS Motameni, Ali; Evis, Zafer; -, -; Department of Engineering Sciences (2021-9-06) In this thesis, mesoporous particles of β-tricalcium phosphate (βTCP, βCa3(PO4)2) and lanthanum (La) doped βTCP were synthesized by wet precipitation method attached with a microwave refluxing system. Pure dicalcium phosphate (DCP) and La modified dicalcium phosphate (La-DCP) bone cements were prepared based on acid/base reaction between βTCP (or La- βTCP) and monocalcium phosphate monohydrate (MCPM) in the presence of water. DCP bone cements were also mixed with 1.5-3.5wt.% of graphene oxide (GO). The obta...
Highly Efficient Room Temperature Synthesis of Silver-Doped Zinc Oxide (ZnO:Ag) Nanoparticles: Structural, Optical, and Photocatalytic Properties Yildirim, Ozlem Altintas; Ünalan, Hüsnü Emrah; Durucan, Caner (Wiley, 2013-03-01) Synthesis of silver-doped zinc oxide (ZnO:Ag) nanoparticles through precipitation method has been reported. The synthesis was conducted at room temperature and no subsequent thermal treatment was applied. ZnO nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), fourier transmission infrared spectroscopy (FTIR), and ultraviolet-visible (UVVis) spectroscopy. Detailed crystallographic investigation was accomplished through ...
Synthesis of iron borophosphates and phosphates with zeo-type structures Tuncel, Selcan; Kızılyallı, Meral; Department of Chemistry (2004) New iron phosphate and borophosphate compounds were synthesized and characterized by single crystal/powder X-ray diffraction, infrared spectroscopy, raman spectroscopy, thermogravimetric analysis, electron microscopy and elemental analysis. Using several compositions, Fey B(PO4)x type of compounds were attempted to be prepared by solid state reactions. The solid state reactions of boron compounds with a phosphating agent has been completed at 950oC. A new product Fe2BP3O12 is synthesized and indexed in this...
Immobilization of invertase in conducting polymer matrices Selampinar, F; Akbulut, Ural; Ozden, MY; Toppare, Levent Kamil (1997-09-01) This paper reports a novel approach in the electrode immobilization of an enzyme, invertase, by electrochemical polymerization of pyrrole in the presence of enzyme. The polypyrrole/invertase and polyamide/polypyrrole/invertase electrodes were constructed by the entrapment of enzyme in conducting matrices during electrochemical polymerization of pyrrole. This study involves the preparation and characterization of polypyrrole/invertase and polyamide/polypyrrole/invertase electrodes under conditions compatible...
STRUCTURAL INVESTIGATION OF NANO HYDROXYAPATITES DOPED WITH Mg(2+) AND F(-) IONS Sun, Z. P.; Evis, Zafer (2009-01-23) Pure and Mg(2+) & F(-) doped nano hydroxyapatites (HA) were synthesized by a precipitation method and sintered at 1100 degrees C to investigate their densification and structure. Different amounts of Mg(2+) and F ions were doped in to HAs. X-ray diffraction was used to identify the presence of phases And lattice parameters of HA and tri-calcium phosphates (TCP) present in the samples. Densification of HA was improved by the addition of these ions. In most of the doped samples, beta-tri-calcium phosphate (TC...
