Methods to improve antibacterial properties of PEEK: A review Uysal, Idil; Tezcaner, Ayşen; Evis, Zafer (2024-03-01) As a thermoplastic and bioinert polymer, polyether ether ketone (PEEK) serves as spine implants, femoral stems, cranial implants, and joint arthroplasty implants due to its mechanical properties resembling the cortical bon...
Boron nitride nanofiber/Zn-doped hydroxyapatite/polycaprolactone scaffolds for bone tissue engineering applications Turhan, Emine Ayşe; Akbaba, Sema; Tezcaner, Ayşen; Evis, Zafer (2023-05-01) In this study, Zn doped hydroxyapatite (Zn HA)/boron nitride nanofiber (BNNF)/poly-ε-caprolactone (PCL) composite aligned fibrous scaffolds are produced with rotary jet spinning (RJS) for bone tissue engineering applicatio...
Additive manufacturing of hexagonal lattice structures: Tensile tests and validation Ture, Mustafa Okan; Evis, Zafer; ÖZTÜRK, FAHRETTİN (2023-04-01) In this paper, different hexagonal lattice structures of the tensile test specimens were designed, manufactured by additive manufacturing, and tested in three different lengths. Moreover, flat shape tensile test specimens ...
3D porous bioceramic based boron-doped hydroxyapatite/baghdadite composite scaffolds for bone tissue engineering Jodati, Hossein; Evis, Zafer; Tezcaner, Ayşen; Alshemary, Ammar Z.; Motameni, Ali (2023-04-01) Making composite scaffolds is one of the well-known methods to improve the properties of scaffolds used in bone tissue engineering. In this study, novel ceramic-based 3D porous composite scaffolds were successfully prepare...
Improvement of bioactivity with dual bioceramic incorporation to nanofibrous PCL scaffolds Altunordu, Gercem; Tezcaner, Ayşen; Evis, Zafer; Keskin, Dilek (2023-03-01) Bone tissue injuries, diseases or related clinical interventions require bone tissue engineering (BTE) approaches for regeneration of large bone defects, especially for compromised situations. Most BTE applications in lite...
Functionalization of graphene oxide quantum dots for anticancer drug delivery Mohammed-Ahmed, Heba K.; Nakipoğlu, Mustafa; Tezcaner, Ayşen; Keskin, Dilek; Evis, Zafer (2023-02-01) Graphene quantum dots (GQDs) have a wide range of applications in biomedical applications, particularly anticancer drug delivery. In this study, graphene oxide quantum dots conjugated with glucosamine and boric acid (GOQDs...
Machining parameters and distortion analyses in end milling of AA2050 and AA7050 Ates, Elvan; Evis, Zafer; ÖZTÜRK, FAHRETTİN (2023-01-01) The machining of high-strength-low-density materials such as AA2050-T84 and AA7050-T7451 has become one of the most important focuses in the development of the aerospace industry. AA7050-T7451 that shows good fatigue resis...
Synthesis and characterization of pure and Mg, Cu, Ag, and Sr doped calcium-deficient hydroxyapatite from brushite as precursor using the dissolution-precipitation method Lakrat, Mohammed; Jodati, Hossein; Mejdoubi, El Miloud; Evis, Zafer (2023-01-01) Calcium-deficient hydroxyapatite (CDHA) is an attractive biomaterial for medical applications due to its similarity with the mineral part of bones. This study presents, for the first time, the preparation of CDHA form brus...
Alginate/gelatin/boron-doped hydroxyapatite-coated Ti implants: in vitro and in vivo evaluation of osseointegration Pazarçeviren, Ahmet Engin; Evis, Zafer; Dikmen, Tayfun; Altunbaş, Korhan; Yaprakçı, Mustafa V.; Keskin, Dilek; Tezcaner, Ayşen (2023-01-01) In this study, boron-doped hydroxyapatite (BHT)-loaded alginate/gelatin-based (A/G) hydrogel coating on Ti was fabricated to support bone integration through triggering osteoinduction, vascularization and immunomodulation....
Fibroin reinforced, strontium-doped calcium phosphate silicate cements for bone tissue engineering applications Işık, Gülhan; Pazarçeviren, Ahmet Engin; Evis, Zafer; Tezcaner, Ayşen (2023-01-01) Calcium phosphate silicate cements (CPSCs) have been developed to overcome problems like high acidity due to presence of brushite and high temperatures evolving as polymethyl methacrylate (PMMA) cements cure at surgery sit...
