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...
Bactericidal and in vitro osteogenic activity of nano sized cobalt-doped silicate hydroxyapatite Alshemary, Ammar Z.; Hussain, Rafaqat; Dalgic, Ali Deniz; Evis, Zafer (2022-10-01) Hydroxyapatite (HA) particles with enhanced antibacterial properties can be prepared by integrating metal ions into the crystal structure of the nanoparticles. Cobalt and silicate ions containing HA (Co/Si-HA) with the formula Ca10-xCox(PO4)6-y(SiO4)y(OH)2 (x = 0.2, 0.6, and 1.0 and y = 0.5) was successfully synthesised by using microwave-assisted wet precipitation method. X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), transmission electron microscopy (TEM), and inductively coupled...
Analysis of protein-protein interaction networks using random walks Can, Tolga; Singh, Ambuj K. (2005-08-21) Genome wide protein networks have become reality in recent years due to high throughput methods for detecting protein interactions. Recent studies show that a networked representation of proteins provides a more accurate model of biological systems and processes compared to conventional pair-wise analyses. Complementary to the availability of protein networks, various graph analysis techniques have been proposed to mine these networks for pathway discovery, function assignment, and prediction of complex mem...
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...
In situ DRIFTS characterization of wet-impregnated and sol-gel Pd/TiO 2 for NO reduction with CH4 Karakaş, Gürkan; Ozkan, Umit S. (Elsevier BV, 2002-05-01) The adsorption/desorption behavior of 2%Pd/TiO2 catalysts synthesized by wet-impregnation and modified sol–gel techniques were examined in NO–CH4–O2 reaction using in situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS). The catalyst prepared by the modified sol–gel method showed significantly higher resistance toward oxygen while maintaining a 100% NO conversion. Under NO+CH4+O2 flow, the main adsorbed NO species was identified as the linearly adsorbed NO on metallic palladium (Pd0–NO)...
