A comparative study of hardness/scratch/wear properties of TiCN and TiAlN coatings on DIN 1.2842 steel by CA-PVD method
Simsir, Mehmet; Palaci, Yuksel; Özer, Ali (Springer, 2021)In the present study, TiCN and TiAlN were deposited on DIN 1.2842 (AISI O2) steel, and their mechanical properties was compared by investigating coating thickness, adhesion strength, microhardness, and elastic modulus. To ... -
An investigation of corrosive effects on zirconia with different crystal structures
Soygun, Koray; Özer, Ali; Ulucan, Mehmet Çağatay; Bolayır, Giray (Wiley, 2021)This study aimed to compare the time-related corrosive resistance in different corrosive solution environments after sintering of zirconia with different crystal structures. The zirconia samples were produced in pellet ... -
Evaluation of the microhardness of different resin-based dental restorative materials treated with gastric acid: Scanning electron microscopy–energy dispersive X-ray spectroscopy analysis
Ünal, Murat; Candan, Merve; İpek, İrem; Küçükoflaz, Merve; Özer, Ali (Wiley, 2021)The aim of this study is to evaluate the microhardness, relative surface roughness, and elemental changes of resin-based dental restorative materials (RDRMs) after gastric acid treatment. Five different RDRMs (Group 1 ... -
Gallium oxide films deposition by RF magnetron sputtering; a detailed analysis on the effects of deposition pressure and sputtering power and annealing
Mobtakeri, Soheil; Akaltun, Yunus; Özer, Ali; Kılıç, Merhan; ŞenadımTüzemen, Ebru; Gür, Emre (Elsevier, 2021)In this study, gallium oxide (Ga2O3) thin films were deposited on sapphire and n-Si substrates using Ga2O3 target by radio frequency magnetron sputtering (RFMS) at substrate temperature of 300 °C at variable RF power and ... -
Investigation of nitrogen doped ZnO thin films: Effects on their structural and optical properties
Hopoglu, H; Aydınoglu, H.S.; Ozer, A.; Senadım Tüzemen, E. (Elsevier, (2021))Un-doped and nitrogen-doped ZnO thin films were grown by using radio frequency (RF) magnetron sputtering method changing the nitrogen flow rate between 0% ����� 12.5% and the thickness dependence of films was determined. ... -
Novel natural spider silk embedded electrospun nanofiber mats for wound healing
Öksüz, Kerim Emre; Kurt Özkaya, Neşe; Şahin İnan, Zeynep Deniz (Elsevier, 2021)In recent years, electrospun nanofiber mats based on biopolymers have been extensively investigated for tissue and biomedical engineering, mainly because of remarkable morphological similarity with the natural ... -
Synthesis and characterization of chitosan–vermiculite composite beads for removal of uranyl ions: isotherm, kinetics and thermodynamics studies
Şenol, Zeynep Mine; Şimşek, Selçuk; Özer , Ali; Şenol Arslan, Dilek (Springer, 2021)In this study, a new material containing Chitosan (Ch)–Vermiculite (V) composite beads was synthesized with epichlorohydrin cross-linking agent and used to remove uranyl ions from the aqueous solution. The prepared new ... -
