this study investigated the photocatalytic behaviors for the nanocomposite of tio2 p25 and semnan natural zeolite in the decomposition of tetracycline under visible light in an aqueous solution. the structural features of the composite were investigated by a series of complementary techniques that included x-ray diffractometer (xrd), fourier transform infrared spectroscopy (ftir), scanning elec...

the proliferation of hepatocellular carcinoma (hcc) cells is one of the leading causes of liver cancer mortality in humans. the inhibiting effects of matrine on hcc cell proliferation have been studied, but the mechanism of that inhibition has not been fully elucidated. since, apoptosis plays an important role in hcc cell proliferation. we examined the apoptosis-inducing effect of matrine on tu...

today, due to qualitative growth and scientific advances, energy, especially electricity is increasingly needed by human society. one of the almost endless and pure energy which have been paid attention over the years is the solar energy. solar cells directly convert solar energy into electrical energy and are one of the main blocks of photovoltaic systems. significant improvement has been made...

nanocomposites of multi-walled carbon nanotubes and titanium dioxide (mwcnt/tio2) were synthesized by the sol-gel method. regarding hydrophobicity of carbon nanotubes (cnts), benzyl alcohol was used as the linking agent between cnt powder and tio2 gel which was prepared from the precursor of titanium tetraisopropoxide. the prepared samples were treated under thermal treatments. a part of the sa...
