We have investigated the Sb and Sb-2 doping of graphene and the effect of Li-n (n=2-4) atoms in detail. We find chemisorption only when we replace C with Sb and Sb-2 and distort the lattice. The additional adsorption of Li atoms changes the electronic band structure of the system.

Copper(0) Nanoparticles Supported on Silica-Coated Cobalt Ferrite Magnetic Particles: Cost Effective Catalyst in the Hydrolysis of Ammonia-Borane with an Exceptional Reusability Performance KAYA, MURAT; Zahmakıran, Mehmet; Özkar, Saim; Volkan, Mürvet (2012-08-01) Herein we report the development of a new and cost-effective nanocomposite catalyst for the hydrolysis of ammonia-borane (NH3BH3), which is considered to be one of the most promising solid hydrogen carriers because of its high gravimetric hydrogen storage capacity (19.6% wt) and low molecular weight. The new catalyst system consisting of copper nanoparticles supported on magnetic SiO2/CoFe2O4 particles was reproducibly prepared by wet-impregnation of Cu(II) ions on SiO2/CoFe2O4 followed by in situ reduction...
Mo doping of layered Li (NixMnyCo1-x-y-zMz)O-2 cathode materials for lithium-ion batteries PİŞKİN, BERKE; Uygur, Cansu Savas; Aydınol, Mehmet Kadri (Wiley, 2018-10-10) We systematically investigated the effects of Mo doping on the structure, morphology, and the electrochemical performance of Li (NixMnyCo1-x-y-zMz)O-2 (NMC) cathode materials for Li-ion batteries. Layered NMC cathodes were synthesized with the ratio of 111, 622, and 226 via spray pyrolysis yielding submicron-sized aggregates in the shape of hollow spherical particles. We performed X-ray diffraction analyses to determine the present phases and the ordering in structure. X-ray diffraction pattern of Mo-doped ...
Electron-phonon scattering in metallic single-walled carbon nanotubes Park, JY; Rosenblatt, S; Yaish, Y; Sazonova, V; Toffoli, Hande; Braig, S; Arias, TA; Brouwer, PW; McEuen, PL (2004-03-01) Electron scattering rates in metallic single-walled carbon nanotubes are studied using an atomic force microscope as an electrical probe. From the scaling of the resistance of the same nanotube with length in the low- and high-bias regimes, the mean-free paths for both regimes are inferred. The observed scattering rates are consistent with calculations for acoustic-phonon scattering at low biases and zone boundary/optical phonon scattering at high biases.
Adsorption of RuSex (x=1-5) cluster on Se-doped graphene: First principle calculations AKTÜRK, OLCAY ÜZENGİ; Tomak, Mehmet (2015-08-30) We have investigated the adsorption of RuSex (x =1-5) cluster on Se-doped graphene. The change of the adsorption energy with the number of Se atoms and magnetization values are investigated. Electronic properties of adsorption of RuSex (x =1-5) cluster on Se-doped graphene are investigated. The highest adsorption energy belongs to RuSe adsorbate. The biggest magnetization value belongs to RuSe2 adsorbate. This adsorbate makes the substrate half metallic. This property is important in electronic device appli...
Magnetic Fe3O4-chitosan micro- and nanoparticles for wastewater treatment ŞAHBAZ, DENİZ AKIN; YAKAR, ARZU; Gündüz, Ufuk (2019-08-18) In this study, first, magnetic nanoparticles (MNP) were synthesized using a coprecipitation method and the synthesized particles were characterized using Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), dynamic light scattering (DLS), and vibrating sample magnetometry (VSM). According to DLS and VSM analyses results, it was seen that the size of the MNP was smaller than 10 nm and they exhibited superparamagnetic properties, respectively. Then, magnetic Fe3O4-chitosan micro/n...
