Dimensional analysis of the thermomechanical problem arising during through-hardening of cylindrical steel components
Şimşir, Caner; Luebben, Thomas; Hoffmann, Franz; Zoch, Hans-Werner (Elsevier BV, 2010-09-01)
This article concerns the dimensional analysis of the complex thermomechanical problem arising during through-hardening of cylindrical steel components. A complete and independent set of physically based dimensionless numb...
Development of electrically conductive porous silk fibroin/CNF scaffolds.
Tufan, Yiğithan; Öztatlı, H; Garipcan, B; Ercan, B (IOP Publishing, 2020-10-22)
Tissue engineering applications typically require 3D scaffolds which provide requisite surface area for cellular functions, while allowing nutrient, waste and oxygen transportation with the surrounding tissues. Concurrentl...
Modeling of reversible gamma/alpha transformations of low carbon steels in the intercritical temperature range
Reti, T; Felde, I; Gür, Cemil Hakan (2004-10-28)
A phenomenological kinetic model has been developed for the prediction of non-isothermal reversible incomplete transformations in low-carbon hypoeutectoid steels. The theoretical basis of the proposed method has its origin...

Guerrero, Martha; Şimşir, Caner; Deus, Augusto; Sarler, Bozidar (Hindawi Limited, 2014-01-01)
Marine Algae-PLA composites as de novo alternative to porcine derived collagen membranes
Sayin, S.; Kohlhaas, T.; Veziroglu, S.; Okudan, E. S.; Naz, M.; Schroeder, S.; Saygili, E.; Acil, Y.; Faupel, F.; Wiltfang, J.; Aktas, O. C.; Guelses, A. (2020-09-01)
Resorbable and volume-stable collagen matrices have been preferred as grafting materials for diverse clinical applications in recent years. On the other hand, there is always an existing risk of transmission of infection w...
Nitrogen effects on radiation response in 12Cr ferritic/martensitic alloys
Aydogan, E.; Gigax, J. G.; Parker, S. S.; Eftink, B. P.; Chancey, M.; Poplawsky, J.; Maloy, S. A. (Elsevier BV, 2020-12-01)
Ferritic/martensitic steels are one of the best candidates for structural materials for high dose applications in next generation nuclear reactors. The composition of structural materials must be optimized for reliable ser...
Enhanced Performance of Nanowire-Based All-TiO2 Solar Cells using Subnanometer-Thick Atomic Layer Deposited ZnO Embedded Layer
Ghobadi, Amir; Yavuz, Halil I.; Ulusoy, T. Gamze; Icli, K. Cagatay; Ozenbas, Macit; OKYAY, Ali Kemal (2015-03-01)
In this paper, the effect of angstrom-thick atomic layer deposited (ALD) ZnO embedded layer on photovoltaic (PV) performance of Nanowire-Based All-TiO2 solar cells has been systematically investigated. Our results indicate...
Characterization and antibacterial efficacy of silver-coated Ca-Na-Zn-Si/Ti glasses
Wren, Anthony; Akgun, Betul; Adams, Brian; Coughlan, Aisling; Mellott, Nathan; Towler, Mark (SAGE Publications, 2012-11-01)
A glass series [xSiO(2[-y])center dot 0.36ZnO center dot 0.17Na(2)O center dot 0.05CaO (starting at x = 0.50, y = 0.08 TiO2)] was formulated with TiO2 substituting SiO2. Each glass/silver-coated glass was characterized usi...
Arpak, Bertan; Araz, Kenan; Nakas, Ipek; Bor, Sakir; Nergiz, Ibrahim (2012-09-01)
To obtain TiNi foams with interconnected pores that have surface quality necessary for bone growth in addition to required mechanical performance, sintering with the space holder technique was employed in this study, which...
A biomechanical comparison between original and used titanium miniplates
Tuncer, N; Demiralp, AS; Guven, O; Keskin, A; Bor, S (Elsevier BV, 1996-02-01)
Four dogs were chosen for this study, An experimental fracture was made in the mandibular symphysis region of each dog. Two miniplates and eight screws mere applied, and removed three and six months postoperatively.
