Atmospheric AACVD Growth of Nd3+: ZnO Thin Films With Temperature‐Optimized Crystallinity and Up‐Conversion Quantum Yield

Rida Elleuch; Marwa ben Chobba; Ikram Benammar; et al.

Thin films doped with rare-earth ions often suffer from poor crystallinity and low up-conversion quantum yield (UCQY), limiting their use in photonic and energy-conversion devices. Nd3+ ions remain particularly underexplored when doped in thin-film, with no…

Dual‑functionalized sulfonated poly (arylene ether sulfone) membranes with sulfonamide crosslinks and octyl grafts for intermediate‑temperature proton exchange fuel cells

Qana A. Alsulami; Walid Mabrouk; Sherif M. A. S. Keshk

Fluorine‐free proton exchange membranes are increasingly required to replace perfluoro sulfonic acid (PFAS) materials in hydrogen fuel cells operating at low humidity and moderate temperatures. In this work, a one‐step grafting–crosslinking strategy was used to fabricate…

Sorption behavior of diclofenac on a kaolinite–biochar composite: adsorption mechanisms and environmental implications

R. Lafi; R. Elleuch; S. Jebri; et al.

Diclofenac sodium (DCF), a common pharmaceutical contaminant, poses risks to both environmental and human health even at low concentrations. Although environmental levels typically fall within the ng/L–µg/L range, this study investigates DCF sorption in the low‑mg/L…

Interfacial modulation in OPVA–ZnO–GO nanocomposites for enhanced proton transport and emission control

Ridha Elleuch; Khaled Charradi; Abdullah Y.A. Alzahrani; et al.

Flexible electronic platforms require polymer nanocomposites that integrate high optical transparency, tunable photoluminescence (PL), and efficient proton transport. Conventional poly(vinyl alcohol) (PVA) systems often suffer from limited chain mobility and poor nanoparticle dispersion, leading to trade-offs…

Modified laser-induced graphene as scaffold for the sensitive and selective sensing of pharmaceutical products

Sabrine Baachaoui; Ismaila Diedhiou; Sherif M.A.S. Keshk; et al.

Diclofenac is a widely used pharmaceutical pollutant that is frequently detected in wastewater and natural waters; however, its reliable on-site quantification remains challenging because of costly instrumentation, labor intensive sample preparation, and electrodes with limited electron-transfer…

Fabrication of transparent, dopant-free OPVA–GO nanocomposites with tunable proton conductivity and optical transparency for photonic and energy applications

Qana A. Alsulami; Khaled Charradi; Fatmah M. Alshareef; et al.

Polyvinyl alcohol (PVA) is valued for its transparency and film-forming ability, but its limited chemical reactivity and weak nanofiller interactions restrict functional tunability. Partially oxidized PVA (OPVA), enriched with ketone and hydroxyl groups, provides a versatile…
