    Abstract: In this research study for the firsttime zirconium doped vanadium oxide nanotubes (VONTs) were synthesized. Zr-doped VONTs were performed by using hydrothermal method. Zr-VONTs prepared 0.02 wt%. The structure and morphology of the nanotubes were investigated by x- ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron ... Show More

    Abstract: This paper focus on the thermal pyrolysis of used tyre with different catalysts at a temperature 550°C and at a heating rate of 15°C/min. The effect of process parameters on liquid yield, char formation and volatiles were also studied. In the present work, thermal pyrolysis of waste tyre samples with two selected catalysts, namely Jordan zeolite (z... Show More

    Abstract: The preparation of pure enantiomers has an increasing demand both for academic and industrial (pharmaceutical) practice. This is not surprising, because the active ingredients of a main part of medicines (about 70-80%) are pure enantiomers. Several selective methods are known for preparation of pure enantiomers but the more economical and usual met... Show More
