CHEMICAL SYNTHESIS OF AlAND CoDOPED $\style{font-family:Arial}{{\mathrm{LiNi}}_6 {\mathrm{Mn}}_2{\mathrm{Fe}}_2{\mathrm O}_2}$ (NMF) CATHODE MATERIAL
Çakmak, Gülhan (2019)Al and Co doped LiNixMnyFezO2 (NMF) was synthesized using sol-gel method. The effect of dopants on the structural stability of LiNixMnyFezO2 (NMF) cathode material was investigated. For this purpose, the powder preparation ... -
Continuous synthesis of graphite with tunable interlayer distance
Çakmak, Gülhan; Öztürk, Tayfur (Elsevier Science Sa, 2019)A study was carried out to produce graphite with controlled interlayer distance synthesized from methane using hydrogen as modifying agent. The synthesis was carried out in radio frequency (r.f.) thermal plasma where the ... -
A dual-doping strategy of LaCoO3 for optimized oxygen evolution reaction toward zinc-air batteries application
Hilal, Mohamed Elhousseini; Şanlı, Seyfettin Berk; Dekyvere, Sander; Çakmak, Gülhan; Younus, Hussein A.; Pişkin, Fatih; Pişkin, Berke; Verpoort, Francis (WILEY, 2022)Perovskite-based electrocatalysts are extensively investigated as a replacement for noble metals electrocatalysts for energy storage and conversion devices. Their interesting catalytic activity, low cost, and diversity are ... -
Effect of Heat Treatment on the Microstructure, Phase Distribution, and Mechanical Properties of AlCoCuFeMnNi High Entropy Alloy
Çakmak, Gülhan (Hindawi Ltd, 2017)The present paper reports the synthesis of AlCoCuFeMnNi high entropy alloy (HEA) with arc melting process. The as-cast alloy was heat treated at 900 degrees C for 8 hours to investigate the effect of heat treatment on the ... -
Rhodium(0), Ruthenium(0) and Palladium(0) nanoparticles supported on carbon-coated iron: Magnetically isolable and reusable catalysts for hydrolytic dehydrogenation of ammonia borane
Akbayrak, Serdar; Çakmak, Gülhan; Öztürk, Tayfur; Özkar, Saim (Elsevier Ltd, 2020)We report the synthesis of magnetically isolable ruthenium(0), rhodium(0), and palladium(0) nanoparticles, supported on carbon-coated magnetic iron particles, and their employment as catalysts in hydrolysis of ammonia ... -
Thermal plasma synthesis of (La,Sr)CoO3-(La,Sr)2CoO4 composite cathodes for intermediate temperature solid oxide fuel cells (IT-SOFC)
Aysal, Havva Eda; Kılıç, Fahrettin; Çakmak, Gülhan; Öztürk, Tayfur (Elsevier Ltd, 2023)(La,Sr)CoO3 and (La,Sr)2CoO4 dual phase powders were synthesized via thermal plasma to be used as cathodes for intermediate temperature solid oxide fuel cells (IT-SOFC). This covered pure (La,Sr)CoO3 as well as the composites ...
