Fabrication, Morphology Analysis, and Mechanical Properties of Ti Foams Manufactured Using the Space Holder Method for Bone Substitute Materials

Çetinel, Oktay; Esen, Ziya; Yıldırım, Bora (MDPI, 2019-03-17)

Porous titanium (Ti) offers several key attributes as a biomedical material. Among the known characteristics of Ti relevant to biomedical applications, the mechanical performance and effects of a pore structure on the ...
Investigation of the Erosive Wear Resistance of Boronized Ash-Blowing Nozzles

Çalık, A.; Özbakır, O.; Karakaş, S.; Uçar, N. (Polish Acad Sciences Inst Physics, 2017-02)

In this study, pack boronizing was applied to ash-blowing nozzles manufactured from AISI 1040 steels using Ekabor II powders as the boronizing source at a temperature of 1273 K for a duration of 8 h. Erosive wear tests of ...
Diffusion Kinetics of Binary Ti-Ni Shape Memory Alloys

Uçar, Nazım; Doğan, Şule; Özdemir, Ahmet Faruk; Karakaş, Mustafa Serdar; Çalık, A. (Polish Acad Sciences Inst Physics, 2017-09)

In this work, the boriding of binary Ti-Ni shape memory alloys was carried out in a solid medium at 1173 and 1273 K for 2, 4, and 8 h using the powder pack method with Ekabor-Ni powders. The boride layer was characterized ...
Synthesis, molecular structure and DFT study of 2-(N-Benzoylbenzamido)pyridine-3-yl benzoate

Yüksektepe, Çiğdem; Kazak, Canan; Özdoğan, Cem; Güvenç, Ziya B.; Büyükgüngör, Orhan; Arslan, Figen; Odabaşoğlu, Mustafa (Springer/Plenum Publishers, 2011-10)

The biologically important 2-amino-3-hydroxypyridine reacts with benzoyl chloride to give 2-(N-benzoylbenzamido)pyridine-3-yl benzoate. This synthesized compound has been studied by elemental analysis, X-ray crystallography ...
Ionization energies, Coulomb explosion, fragmentation, geometric, and electronic structures of multicharged boron clusters B-n (n=2-13)

Akman, Nurten; Taş, Murat; Özdoğan, Cem; Boustani, Ihsan (Amer Physical Soc, 2011-08-11)

Based on the ab initio quantum chemical methods, we have determined fragmentation channels, ionization energies, and the Coulomb explosion of multicharged boron clusters B-n (n = 2-13), where n is the cluster size. The ...
Stability of edge states and edge magnetism in graphene nanoribbons

Kuntsmann, Jens; Özdoğan, Cem; Quandt, Alexander; Fehske, Holger (Amer Physical Soc, 2011-01-21)

We critically discuss the stability of edge states and edge magnetism in zigzag edge graphene nanoribbons (ZGNRs). We point out that magnetic edge states might not exist in real systems and show that there are at least ...
Characterization of Ti-6Al-4V alloy foams synthesized by space holder technique

Esen, Ziya; Bor, Şakir (Elsevier Science S A, 2011-03-25)

Ti-6Al-4V foams, biomedical candidate materials, were synthesized by powder metallurgical space holder technique as a result of evaporation of magnesium to achieve desired porosity content. Final products contained porosities ...
