DOI: 10.1007/s11060-017-2621-7

Abstract: Expression of CD44 in glioma cells was previously correlated with tumor grade and is considered a stem cell marker. CD44 stabilizes the cystine–glutamate transporter (xCT) and inhibits apoptosis in cancer stem cells (CSCs). Recently it… read more here.

DOI: 10.1016/j.apcata.2019.117119

Abstract: Abstract In this work, CuOx/Chabazite(CHA, SSZ-13, SAPO-34 etc) catalysts were prepared by wet impregnation method for ammonia selective catalytic oxidation. CuOx/H-SSZ-13 exhibited superior NH3 conversion and N2 selectivity compared with CuOx/H-SAPO-34 below 300 °C under both… read more here.

DOI: 10.1016/j.cattod.2017.05.073

Abstract: Abstract The conversion of Y-zeolites having a wide silica/alumina ratio (SAR, 5.2–80) into other zeolites was attempted using tetraethylammonium hydroxide (TEA-OH) as an organic structure directing agent (SDA). Depending on the SARs of the Y-zeolites,… read more here.
