Performance of polysulfone ultrafiltration membranes incorporating graphene oxide nanoparticles functionalized with different generations of poly(amido amine) by Ahmed T. Yasir (17302753)

“…GO-PAMAM nanocomposites synthesized by phase inversion method were incorporated in different synthesized polysulfone membranes matrices and the effect of GO-PAMAM nanoparticles of different PAMAM generations on performances of the modified polysulfone membranes was assessed. FTIR, analysis of the synthesized nanocomposites confirmed the presence of various amine groups on the surface of graphene oxide (GO), while XRD and Zeta potential analyses revealed reduced GO crystallinity and increased zeta potential values respectively. …”

Graphene oxide/chitosan doped polysulfone membrane for the treatment of industrial wastewater by Ahmed T. Yasir (17302753)

“…Maintaining the same GO-CH composition of 0.085 wt% and changing GO to CH ratio to 1:1 resulted in better hydrophilicity (contact angle 68°) and increased reversible fouling from 23 to 33%. The best membrane was further tested with real industrial wastewater obtained from a GTL plant in Qatar showed 28% improvement in COD removal.…”

An Insight Into Unveiling Nano Luminescence for Industrial Dye Detection by E. Safamariyam (22330186)

“…The CQDs were characterised using SEM, XRD, FTIR, UV–Vis spectrophotometry, and photoluminescence, which confirmed their uniform size distribution and outstanding optical characteristics. …”

Enhancing the quality of lentil proteins via combination with whey proteins based on a dual process: a novel strategy through the incorporation of complexation and fermentation by Mohammad Alrosan (20089263)

“…The protein digestibility, pH values, microbial growth, total soluble solids, and total saponin and phenolic contents were hydrolyzed for 5 days at 25 °C. The FTIR spectrophotometer scans indicated significant (<i>P</i> < 0.05) changes to the secondary protein structure components (random coil and α-helix). …”
