Optoelectronic properties of highly porous silver oxide thin film by Ahmad Al-Sarraj (17151007)

“…The obtained results indicate the formation of mixed mesoporous Ag₂O and AgO NW thin films. The Ag₂O phase of silver oxide appears after 300 s of oxidation under the same conditions, while the optical transparency of the thin film decreases as plasma etching time increases. …”

Antibacterial Properties of Polysulfone Membranes Blended with Arabic Gum by Souhir Sabri (9553808)

“…A pronounced decrease in bacterial attachment was seen in the field emission scanning electron microscopy (FESEM) images for PS/AG membrane samples compared to both commercial (Microdyn-Nadir) and bare PS (without AG) membranes. …”

Evaluation of the cementite morphology influence on the hydrogen induced crack nucleation and propagation path in carbon steels by Shabnam Karimi (19457575)

“…The ECCB tests were performed in H-free and two H charging steps with −1050 mV and −1550 mV charging potential versus Ag/AgCl reference electrode. The results show that both materials are resistant to crack initiation in the H-free condition while under −1050 mV charging, crack propagates through the grain boundaries in a tortuous path in spheroidite mi-crostructure and the lamellar microstructure displayed a higher strength with small cracks propagating through both the grain boundaries and the lamellas. …”

Mirizzi Syndrome: Mastering the Challenge, Characterization and Management Outcomes in a Retrospective Study of 60 Cases by Yousef Yahia (19756989)

“…Laparoscopic cholecystectomy was the most common surgical approach (76.7%), particularly in type 1 (79.6%), and decreased to 50% in advanced types. Hepaticojejunostomy was more common in the advanced types.…”

Investigation of the structural, optical and gas sensing properties of PANI coated Cu–ZnS microsphere composite by Hemalatha Parangusan (6556133)

“…The emission peaks obtained in photoluminescence spectra confirm the presence of surface defects in the prepared composite. The UV-DRS study shows that the bandgap of the samples is found to decrease for the PANI/Cu–ZnS composite compared to the pure Cu–ZnS sample. …”

Intravenous administration of gold nanoparticles in rats exhibit alterations in sphingomyelins, bile acids, sphingolipids, and cholesterol esters levels by Haya Al-Sulaiti (5449256)

“…Gold (AuNPs) and silver (AgNPs) NPs are among the important nanoplatforms that received extensive attention recently for various biomedical applications. …”

Control of the Speed of a Light-Induced Spin Transition through Mesoscale Core-Shell Architecture by Slimani, Ahmed

“…A series of photomagnetic coordination polymer core-shell heterostructures, based on the light-switchable RbaCob[Fe(CN)6]c·mH2O (RbCoFe-PBA) as core with the isostructural KjNik[Cr(CN)6]l·nH2O (KNiCr-PBA) as shell, are studied using temperature-dependent powder X-ray diffraction and SQUID magnetometry. …”
