Chemical and structural optimization of ZnCl2 activated carbons via high temperature CO2 treatment for EDLC applications
(Pergamon-Elsevier Science Ltd, 2018)Development of biomass based activated carbon materials for electrical double layer capacitor (EDLC) usage has gained attention as a result of requesting efficient and low cost energy storage device production. In this ... -
Deformation behaviour of a new Magnesium ternary alloy
(Amer Inst Physics, 2018)Magnesium based alloys are yet to fill a greater niche especially in the automotive and aeronautical industry. In fact, such alloys have a big weight saving potential, together with good damping characteristics. However, ... -
DEVELOPMENT OF HYDROGEN PURIFICATION MEMBRANE BASED ON Pd-Mn-Ag TERNARY SYSTEM
(International Association for Hydrogen Energy, IAHE, 2022)In this paper, we investigate Pd-Mn-Ag ternary system for potential alloys as separation membranes. For this purpose, thin film membranes of varying compositions were produced via magnetron sputtering. These were evaluated ... -
Development of rolling technology for twin roll casted 1500MM wide magnesium AZ31 alloy
(Minerals, Metals & Materials Soc, 2009)Magnesium alloy AZ31 sheets of 4.5-6.5mm thick and 1500mm width were produced by twin roll strip casting first time in Turkey. Afterwards, sheets were hot and cold rolled down to less than 1mm both by laboratory and ... -
Forming Behaviour at Elevated Temperature of a Laser Heat-Treated AZ31 Magnesium Alloy Sheet
(Trans Tech Publications Ltd, 2018)The tailoring of mechanical and technological properties of the initial material in sheet metal forming has been widely investigated and successfully applied. The benefits of such an approach can be found in the improvement ... -
Large magnetocaloric effects in magnetic intermetallics: First-principles and Monte Carlo studies
(E D P Sciences, 2015)We have performed ab initio electronic structure calculations and Monte Carlo simulations of frustrated ferroic materials where complex magnetic configurations and chemical disorder lead to rich phase diagrams. With lowering ... -
Mechanical and microstructural evaluation of solid-state foamed Ti6Al4V-ELI alloy
(Elsevier B.V., 2022)Metallic materials adopted in biomedical applications play a key role in the replacement of so-called "hard tissues" (the human bone). Titanium (Ti) alloy prostheses are considered the best among all metallic implants due ... -
Mechanical characterization of highly porous beta-Si3N4 ceramics fabricated via partial sintering & starch addition
(Elsevier Sci Ltd, 2013)In this study, porous beta-Si3N4 ceramics containing limited amount of Sm2O3 and CaO as sintering aids were produced by addition of potato starch (10 and 20 vol.%) and partial sintering. Two different Si3N4 powders, alpha- ... -
Metal ve seramik tozlarının bilgisayar kontrollü tek eksenli kalıpta preslenmesi
(1999)This study is about the investigation of the mechanical properties of metal and ceramic powders pressed by a uniaxial die. The bronze powders have spherical particles, copper powders are of oval, iron powders are of porous ... -
Morphology effect on electrochemical properties of doped (W and Mo) 622NMC, 111NMC, and 226NMC cathode materials
(Pergamon-Elsevier Science Ltd, 2020)An investigation was carried out on layered Li(NixMnyCo1-x-y)O-2 (NMC) cathode active materials for Li-ion batteries to determine the effect of morphology on their electrochemical performances. The NMC active materials ... -
Non-volatile high-temperature shell-magnetic pinning of Ni-Mn-Sn Heusler precipitates obtained by decomposition under magnetic field
(Elsevier Science Bv, 2018)The thermodynamic instability of the off-stoichiometric Ni49.8Mn45.1Sn5.1 martensitic Heusler causes it to decompose into ferromagnetic Ni50Mn25Sn25 precipitates and an antiferromagnetic NiMn matrix. If the decomposition ... -
Preventing of LaNiO3 Formation at the LSGM-NiO Interface via LDC Protective Layer and Proper Processing Route for Solid Oxide Fuel Cells
(Electrochemical Soc Inc, 2017)LSGM based SOFCs suffer from performance degradation during operation, especially with Ni-containing anodes. One of the causes for performance degradation in an LSGM-based SOFC system was investigated. XRD and SEM studies ... -
