DEVELOPMENT OF POLYMER MATRIX COMPOSITES WITH TUNABLE DIELECTRIC PROPERTIES
Özkaragöz, Nadire Nazlı; Dericioğlu, Arcan Fehmi; Department of Metallurgical and Materials Engineering (2022-2-08)
Ferroelectric materials are used in different applications because of their superior electrical and dielectric properties. Ferroelectric materials are polarized when an electrical field is applied to the material. This spontaneous polarization continues even if an electrical field is removed. BST (Barium Strontium Titanate) is one of the attractive ferroelectric materials which has a high dielectric constant and low dielectric loss tangent (tanδ). High dielectric constant and low loss tangent are necessary ...
Development of anodes for direct oxidation of methane fuel in solid oxide fuel cells
Akdeniz, Yelda; Timurkutluk, Bora; Timurkutluk, Cigdem (2016-06-22)
In addition to pure hydrogen, solid oxide fuel cells (SOFCs) can utilize hydrocarbons as a fuel. However, conventional Ni-based anodes exhibit an excellent catalytic activity towards the hydrocarbon cracking reaction and thus the carbon deposition occurs in the anode. The deposited carbons quickly deactivate the anode irreversibly by covering the active surface of the anode catalyst. As a result, a significant degradation in the cell performance can be seen. In this study, the anode structure is modified by...
Development of magnesium potassium phosphate cement pastes and mortars incorporating fly ash
Bilginer, Baki Aykut; Erdoğan, Sinan Turhan; Department of Civil Engineering (2018)
Magnesium potassium phosphate cements (MKPCs) have some promising properties to be considered as an alternative to ordinary Portland cement binders. The favorable properties of these cements are high early and ultimate strength. On the other hand, they have some problems like rapid setting, high heat of reaction, high cost and poor water stability. In this study, the effect of several factors like magnesium-to-phosphate molar ratio (M/P), water-to-binder ratio (W/B) and retarder (borax) content on propertie...
Development of cathode materials for li-ion batteries by sputter deposition
Erdoğan, Erdem Erkin; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2022-2-10)
The electrochemical performance of Li-ion batteries depends mostly on the cathode material. Cobalt has a huge impact on electrochemical properties and is widely used in cathode materials, but due to its toxicity and cost, recent research is focused on reducing the amount of cobalt in cathode materials. In this study, cathode active materials are produced by magnetron sputtering to obtain the optimum amount of cobalt while optimizing the electrochemical properties. Pechini sol-gel method is used to produce p...
Development of activated carbon/bimetallic transition metal phosphide composite materials for electrochemical capacitors and oxygen evolution reaction catalysis
Köse, Kadir Özgün; Aydınol, Mehmet Kadri (2022-09-01)
Pinecone-derived activated carbon (AC) and bimetallic transition metal phosphide (TMP) composites were produced and utilized as electrochemical capacitor (EC) electrodes and oxygen evolution reaction (OER) catalysts in this study. The base transition metal (TM) was Ni for all samples, and the secondary TM was one of Fe, Mn and Co. AC serves as a porous structure for double layer formation and active sites for OER catalysis. Bimetallic TMP is utilized due to redox reactions in EC and catalytic activity in OE...
