Opis:: Tin dioxide nanoparticles were synthesized by sol-gel method and calcined at different temperatures in the range 350-750°C. The $SnO_2$ precursor solution was prepared from $SnCl_2$·$2H_2O$ (tin (II) chloride dihydrate), and chloride ions were removed from the solution before the sol-gel synthesis was applied. $SnO_2$ powders were characterized by thermal analyses, X-ray diffraction, field emission gun-scanning electron microscopy, and energy dispersive X-ray spectroscopy, and grain size of nanoparticles were determined by using the Debye-Scherrer formula.

Opis:: In this study, a bronze matrix (90 wt% Cu + 10 wt% Sn) was reinforced with $Al_2O_3$ particles using mechanical alloying and then produced by a subsequent rapid current sintering technique. The mechanically ball milled bronze powders were reinforced with electroless Ni coated 20 vol.% $Al_2O_3$ particles with three different particle sizes of 90, 70, and 50 μm. Microhardness testing, and scanning electron microscopy were used for the structural characterization of the composites. The tribological behavior of the resultant composites was tested by the ball-on-disk method at 1.0 N applied load with 0.3 m/s sliding speed for determination the wear loss and friction coefficient features against a counterface steel ball.

Opis:: In this study, silicon/multi-wall carbon nanotube (Si/MWCNT) and silicon/molybdenum/multi-wall carbon nanotube (Si/Mo/MWCNT) composites were produced by high speed planetary ball milling. Produced Si/MWCNT composite containing 50 wt.% Si and 50 wt.% MWCNT and dispersingdifferent amount of molybdenum nanopowders (1 wt.%, 3 wt.% and 5 wt.%) Si/Mo/MWCNT composites were produced by high speed planetary ball milling. Surface morphology of produced composite electrodes was characterized using scanning electron microscopy (SEM) and EDS dot-map analyze was performed to investigate dispersion of MWCNT and molybdenum powders in the composite structure. X-ray diffraction (XRD) technique was carried out to investigate structure of produced Si/Mo/MWCNT composites. Electrochemical performance of the electrodes were tested between 50 mV and 1.5 V in CR2016 test cell.

Opis:: Silicon/MWCNT composite electrodes were produced using high-speed planetary ball milling. Content of MWCNT were altered in silicon/MWCNT composite electrodes and effect of MWCNT content on the electrochemical performance of silicon electrodes were characterized by scanning electron microscopy and X-ray diffraction techniques. Coin type CR2016 test cells were assembled by using produced nanocomposite electrodes. Prepared test cells were electrochemically cycled at a current density of 200 mA/g. Furthermore, cyclic voltammetry curve of composite electrodes were performed to investigate electrochemical reactions between electrode and electrolyte.

Opis:: Mixed silicon/graphite anode materials were produced via mechanical milling process. The morphologies of mixed powders and electrodes were characterized via scanning electron microscopy and X-ray diffraction pattern. Electrochemical tests were performed by coin-type (CR2016) test cells. The cells were cyclically tested on a battery tester, and discharge capacities of produced anode materials were investigated with using constant current 300 mA/g over a voltage range of 80 mV-1.2 V.
