Mechanical properties of monolayer GaS and GaSe crystals
(American Physical Society, 2016-12)The mechanical properties of monolayer GaS and GaSe crystals are investigated in terms of their elastic constants: in-plane stiffness (C), Poisson ratio (ν), and ultimate strength (σU) by means of first-principles calculations. ... -
Merger dynamics in three-agent games
(Springer, 2011-09)We present the effect of mergers, a term which we use to mean a temporary alliance, in the dynamics of the three-agent model studied by Ben-Naim, Kahng and Kim and by Rador and Mungan. Mergers are possible in three-agent ... -
Metal ion release from nitrogen ion implanted CoCrMo orthopedic implant material
(Elsevier, 2006-05)CoCrMo alloys are used as orthopedic implant materials because of their excellent mechanical and corrosion properties. However, when placed in vivo, these alloys release Co, Cr, Mo ions to host tissues, which may give rise ... -
Metal ion release from TiN coated CoCrMo orthopedic implant material
(Elsevier, 2006-04)In this study, a medical grade CoCrMo alloy was coated with TiN by means of physical vapor deposition (PVD) technique at 550 °C for 6 h. The TiN layer microstructure and thickness were studied by X-ray diffraction (XRD) ... -
Metal mesh filters based on Ti, ITO and Cu thin films for terahertz waves
(Springer, 2016-02-01)In this study, we have investigated the spectral performance of resonant terahertz (THz) bandpass filters which were produced from thin films with a metal-mesh shape. The aforementioned filters were fabricated from titanium, ... -
