Functionalization of reverse osmosis membrane with graphene oxide to reduce both membrane scaling and biofouling حسب Mohammad Y. Ashfaq (14152290)

"…Results indicated that the permeate flux was reduced by only 15% at the end of the scaling experiment as opposed to the bared RO membrane which faced up to 22% decline in flux. The results of scanning electron microscopy, Fourier transform infrared, and X-ray diffraction confirmed that the bared RO membrane was extensively scaled by the CaSO4 precipitates. …"

Klotho overexpression protects human cortical neurons from β-amyloid induced neuronal toxicity حسب Mohammed R. Shaker (10316180)

"…Our data reveal that upregulation of <i>KLOTHO</i> significantly reduced β-amyloid-induced neuronal degeneration and apoptosis, as evidenced by decreased cleaved caspase-3 expression and preservation of axonal integrity. …"

Performance and analysis of kappa-carrageenan hydrogel for PFOA-contaminated soil remediation wastewater treatment حسب Alsaka, Lilyan

"…Due to pore size shrinkage, the AC-kC and V-kC hydrogels achieved the highest PFOA rejection at pH 4, whereas the water flux decreased. Increasing the PFOA concentration reduced water flux and increased PFOA rejection. …"
