ED AX energy-dispersive X-ray

The Pt Ru atomic ratios were obtained by Energy dispersive X-ray analysis (EDX) using a scanning electron microscope (SEM) Phillips XL30 with a 20 keV electron beam and equipped with ED AX DX-4 microanaliser. 

Characterization. CHNS analysis was carried using the Thermo Finnigan FLASH EA 1112 CHNS analyzer. Energy dispersive analysis of X-rays (EDAX) was carried using the OXFORD ED AX system. Infrared spectroscopic studies of KBr pellets were recorded in the mid-IRregion (Bruker IFS-66v). Thermogravimetric analysis was carried out (Metler-Toledo) in nitrogen atmosphere (flow rate... 

BN nanotubes were prepared by a standard literature procedure.7 BN nanotubes were prepared by the reaction of B2C>3 with multi-walled carbon nanotubes (MWNTs) in the presence of ammonia at 1250 °C for 3 h. A grey spongy product was obtained after the reaction indicating the presence of unreacted MWNTs along with BN nanotubes. The product was washed with hot water to remove excess B2O3. The excess carbon present in the product was removed by oxidation at 800 C in low-pressure air (20 mPa). Scanning electron microscope (SEM) and energy dispersive analysis of X-rays (ED AX) were performed with...
