A different method for producing a flexible LiMn2O4/MWCNT composite electrode for lithium ion batteries

Çetinkaya, Tuğrul; Akbulut Uludağ, Ahsen; Güler, Mehmet Oğuz; Akbulut, Hatem (VAN GODEWIJCKSTRAAT 30, 3311 GZ DORDRECHT, NETHERLANDS, 2014)

A flexible lithium manganese oxide (LiMn2O4)/multi-wall carbon nanotube (MWCNT) composite electrode was produced by casting a slurry-containing powdered LiMn2O4 on a previously prepared MWCNT paper. The structure of this ...
Electrons, phonons and superconductivity in rocksalt and tungsten-carbide phases of CrC

Tütüncü, Hüseyin Murat; Bağcı, Sadık; Akbulut Uludağ, Ahsen (IOP PUBLISHING LTD, 2012)

We present results of ab initio theoretical investigations of the electronic structure, phonon dispersion relations, electron-phonon interaction and superconductivity in the rocksalt and tungsten-carbide phases of CrC. It ...
High stable Li-air battery cells by using PEO and PVDF additives in the TEGDME/LiPF6 electrolytes

Akbulut Uludağ, Ahsen; Tokur, Mahmud; Algül, Hasan; Çetinkaya, Tuğrul; Uysal, Mehmet; Akbulut, Hatem (PERGAMON-ELSEVIER SCIENCE LTD, 2016)

An ether based electrolyte containing TEGDME/LiPF6 was optimized, which possessed low viscosity and high ionic conductivity, under dry argon atmosphere in a glove box. In order to prevent air breathing cathode clogging by ...
Stability effect of some organic and inorganic additions in the EMITFSI-LiTFSI nanocomposite electrolytes for lithium-air batteries

Akbulut Uludağ, Ahsen; Akbulut, Hatem; Tokur, Mahmud; Algül, Hasan; Çetinkaya, Tuğrul; Uysal, Mehmet (SPRINGER HEIDELBERG, 2016)

Since the EMITFSI/LiTFSI electrolyte possess low viscosity, high ionic conductivity and thermal stability properties, in this study, 1M 1-ethyl-3-methyl-imidazoliumbis (trifluoromethanesulfonyl) imide (EMITFSI)/Lithium bis ...
The Effect of Calcination Temperature on the Electrochemical Performance of ZnO Coated LiMn2O4/MWCNT Nanocomposite Cathodes

Akbulut Uludağ, Ahsen; Çetinkaya, Tuğrul; Akbulut, Hatem (AL LOTNIKOW 32-46, PL-02-668 WARSAW, POLAND, 2014)

In this study, it is aimed to develop LiMn2O4/MWCNT nanocomposite cathode materials by using different calcination temperatures (300, 500, 700 degrees C). The aim of using MWCNTs in the active material is to overcome poor ...
The effect of MWCNT reinforcing on the electrochemical performance of LiMn2O4/MWCNT nanocomposite cathodes

Akbulut Uludağ, Ahsen; Akbulut Uludağ, Ahsen; Çetinkaya, Tuğrul; Akbulut, Hatem (WILEY-BLACKWELL, 2014)

In this study, nanocrystalline LiMn2O4 cathode materials were synthesized by a facile sol-gel method and were then mechanical alloyed with varying amounts of MWCNTs in order to obtain a high capacity nanocomposite cathode ...
Withdrawal of Staphylococcus aureus from intensive care units in Turkey

Karabay, Oğuz; Akbulut Uludağ, Ahsen (MOSBY-ELSEVIER, 2013)

Conclusions: The incidence of S aureus infections is declining rapidly in Turkish ICUs, with potential impacts on empirical treatment strategies in these ICUs. Copyright (C) 2013 by the Association for Professionals in ...
