Electrophoretic Coating of Hydroxyapatite-Boron Nitride Nanocomposites on Titanium Implants

Bakan F., Sezen M., Goncu Y., Ay N., Sabanci University, TR

Titanium (Ti) and its alloys have long been used as implant materials in dental and orthopedic applications. However, they can suffer certain disadvantages, such as poor osteoinductive properties and low corrosive-wear resistance. The potential of [...]

Synthesis and Characterization of Novel Multifunctional SiO2 nanoparticles

Aslan A., Bozkurt A., Soydan A.M., Ata A., Gebze technical university, TR

In the present work, azole functional silica nanoparticles synthesized and characterized. For the preparation of azole functional SiO2, a two-step method based on hydrolyzed of TEOS was used in this study. The epoxy functional SiO2 [...]

Nanoanalysis of Gas Assisted Ion Etching of High Density Polyethylene using FIB/SEM Platforms for the Development of Functional Surfaces

Sezen M., Bakan F., Sabanci University, TR

Although soft matter, such as polymers, are very much prone to react on electron/ion beam irradiation, it is well possible to turn degradation dependent physical/chemical changes from negative to positive when materials are exposed to [...]

The Effect of Sintering Conditions on the Formation of Hydroxyapatite-Boron Nitride Nanocomposites

Bakan F., Sezen M., Goncu Y., Ay N., Gecgin M., Sabanci University, TR

Being the main inorganic constitution of hard tissues (bone and teeth),calcium phosphates has been applied in medical and dental applications in hard tissue repair. Hydroxyapatite (HAp) ceramics have attracted attention because of their excellent osteoconductive [...]
