Introduction
In January 2020, I joined Unallab and Koc University Surface Science and Technology Center (KUYTAM) as a Ph.D. Student. My research focuses mainly on metallic thin films, magnetron sputtering, and high-entropy alloys for biomedical and electrocatalyst applications.

The aim of the current study is to develop and evaluate antibacterial and biocompatible refractory high-entropy alloy (RHEAs) film using RF magnetron sputtering technique. For this purpose, Ti1.5ZrTa0.5Nb0.5W0.5 RHEA film and its Ag nanoparticle doped analog (with an Ag content of 9 atomic %) were deposited on Ti6Al4V substrate. The microstructural...
Even though metallic biomaterials have long been utilized as the key materials in biomedical applications due to their exceptional mechanical properties, corrosion and bacterial infection problems place a limit on their prolonged clinical applications. In order to overcome such problems, surface modification of the implants via exerting a durable a...
Light-weight high entropy alloys (LWHEAs) are considered equiatomic or near-equiatomic alloys consisting of at least five elements. Low-density elements, like Al and Ti, are the key constituents in designing these alloys so that features such as reduced overall density and improved mechanical properties are achieved.
A new LWHEAs (Al2CrFeMnTi) is d...
In the present research, a non-equimolar Ti1.5ZrTa0.5Nb0.5Hf0.5 RHEA film with a thickness of 1.025 µm was deposited on 316 L, CoCrMo, and Ti6Al4V substrates by RF magnetron sputtering system. The microstructural characterizations showed that an amorphous and compact film with a continuous and cauliflower-like morphology was developed on the substr...
In recent years, 3D assemblies of graphene are developed as promising materials in various applications, such as energy storage devices. In this paper, we have reported a method for the synthesis of Graphene Aerogel (GA) utilizing a novel reducing system to achieve high electrochemical properties. GAs were obtained via chemical reduction of Graphen...
The electrodeposition technique was used to produce Co, Co/micro-Al2O3, and Co/nano-Al2O3 coatings. The effect of particle size on current efficiency, thickness, composition, morphology, and structure of the coatings was investigated. The potentiodynamic polarization technique and electrochemical impedance spectroscopy was used to study the corrosi...
