Oxide coated nickel powder as support for platinum(0) nanoparticles: Magnetically separable catalysts for hydrogen generation from the hydrolysis of ammonia borane Akbayrak, Serdar; Çakmak, Gülhan; Öztürk, Tayfur; Özkar, Saim (2024-10-15) We report the development of a novel method for the preparation of magnetically separable platinum nanoparticles. Magnetic nickel nanopowder is initially synthesized in a radiofrequency plasma reactor where in-line passiva...
A combinatorial study on ZnO-In2O3-SnO2 system: The effects of different postgrowth annealing conditions on optical and electrical properties Can, Hilal Aybike; Öztürk, Tayfur; AKYILDIZ, HASAN (2022-11-01) ZnO-In2O3-SnO2 (ZITO) thin film library was produced via the combinatorial approach. The films were deposited using a magnetron sputtering system. Varying ZITO compositions were obtained in a single deposition run by emplo...
A novel air-stable O3-type layered oxide cathode material with low Ni content for sodium-ion batteries Patat, Şaban; Şahin, Ayşe; Taş, Yusuf; Şanlı, Ferhat; Yılmaz, Yakup; Öztürk, Tayfur (2022-06-01) A novel O3-NaMn0.42Fe0.42Ni0.17O2 cathode material for sodium-ion batteries is synthesized, for the first time, by a co-precipitation method followed by solid-state reaction. The effect of Ni2+, Cu2+ and Ca2+ substitution ...
Processing optimization of SiO2-capped aluminum-doped ZnO thin films for transparent heater and near-infrared reflecting applications Can, Hilal Aybike; Tonbul, Beyza; PİŞKİN, FATİH; Öztürk, Tayfur; AKYILDIZ, HASAN (2021-01-01) In this study, a series of optimization steps were performed in the production of Al-doped ZnO (AZO) thin films to tailor their properties as efficient transparent heaters and for near-infrared (NIR) reflectance. The films...
Segregation resistant nanocrystalline/amorphous (La, Sr) CoO3-(La,Sr)2CoO4 composite cathodes for IT-SOFCs Sari, Dogancan; Yaşar, Bengisu; Pişkin, Fatih; Kalay, Yunus Eren; Öztürk, Tayfur (2019-01-01) There is a considerable interest in lowering the operating temperature of solid oxide fuel cells. In this respect, (La,Sr)CoO3(La,Sr)(2)CoO4 dual phase oxides have attracted much attention as cathode materials due to their...
Plasma Synthesis of AlNiCo Core/Shell Nanopowders Genç, Ayşe Merve; Öztürk, Tayfur; Kalay, Yunus Eren (2018-11-26) Aluminum-nickel-cobalt (AlNiCo) permanent magnets revolutionized the permanent magnet industry in 1920’s but has not been thoroughly studied after the development of powerful rare-earth permanent magnets. As compared to ra...
Combinatorial development of nanocrystalline/amorphous (La,Sr)CoO3-(La,Sr)2CoO4 composite cathodes for IT-SOFCs Sari, Doğancan; Piskin, Fatih; Torunoglu, Ziya Cagri; Yasar, Bengisu; Kalay, Yunus Eren; Öztürk, Tayfur (2018-11-15) In this study, a combinatorial approach was used to develop cathode materials with improved performance at temperatures in the range 500-700 degrees C. A thin film composite cathode library was obtained by co-sputtering of...
Preface: 2nd International Symposium on Materials for Energy Storage and Conversion (mESC-IS2017) Öztürk, Tayfur (2018-10-04)
Synthesis of Dual Oxide Cathode for IT-SOFCs via Th ermal Plasma Aysal, Havva Eda; Sarı, Doğancan; Pişkin, Fatih; Öztürk, Tayfur (2018-09-25) The composition and microstructure of cathode materials has a large impact on the performance of solid oxide fuel cells (SOFCs). It was recently shown that the sputter deposited (La0.8Sr0.2) CoO3 (LSC-113) - (La0.5Sr0.5)2C...
Surface Modified Metal Hydrides as Negative Electrode s for NiMH Batteries Eyövge, Cavit; Şahin, Ezgi Onur; Öztürk, Tayfur (2018-09-17) There is a renewed interest in NiMH batteries with improved energy densities that could approach those of Li-ion batteries. Efforts to improve the energy density concentrates on alternative anode as well as cathode materia...
