    (Elsevier Sci Ltd, 2024) Hussaini, Ali Akbar; Sarılmaz, Adem; Özel, Faruk; Erdal, Mehmet Okan; Yıldırım, Murat
    Despite being a relatively new technology, low-cost 3D printing has exhibited a significant impact on many facets of daily life. 3D printing has gained its popularity due to its ease of designing, quick prototyping, and waste reduction. In this study, we synthesized CeO2/BaMoO4 nanocomposite and characterize it with UV-vis, XRD, and SEM. Band gap of CeO2/BaMoO4 was found as 3.17 eV, showing an excellent semiconductor behavior. We also fabricated affordable 3D-printed working electrodes for application in dopamine hydrochloride detection. CeO2/BaMoO4 were modified onto 3D-printed electrodes and commercially purchased screen-printed electrodes to compare its applicability in dopamine detection. Electroactive surface areas were enhanced by addition of CeO2/BaMoO4. In linear range of 5-1000 mu M, limit of detection values were found as 4.52 mu M and 2.77 mu M for CeO2:BaMoO4/SPE and CeO2:BaMoO4/3DPE biosensors, respectively. Sensitivity was calculated as 8.7285 and 0.3142 A/M.cm(2) for CeO2:BaMoO4/SPE and CeO2:BaMoO4/3DPE, respectively. Both devices have shown significant reproducibility, repeatability and selectivity.

    Fabrication of hydrophobic waste based-microfibers ıncorporated with green synthesized metal oxides for oil/water separation applications
    (Springer Science and Business Media B.V., 2025) Dilber, Abdülkadir; Hussaini, Ali Akbar; Durmaz, Fatih; Ulukus, Deniz; Yıldırım, Murat
    Developing affordable, long-lasting, and effective membranes is essential for the treatment of oily wastewater, which has become a substantial problem. In this study, an affordable and environmentally-friendly hydrophobic microfibers were designed. Polystyrene wastes were recycled into a functional hydrophobic microfiber. ZnO, CuO, and CuO-ZnO nanoparticles were synthesized using pine pollen waste via green approach. Thereafter, green synthesized nanoparticles were incorporated into recycled polystyrene to fabricated an efficient microfiber. Fabricated microfibers were characterized via FT-IR and XRD, SEM and SEM–EDS. Water contact angle of the polystyrene nanofibers were increased from 123.5° to 139.1° by metal oxide incorporation. Separation efficiency of the polystyrene microfiber was also improved by addition of green synthesized CuO to 81.84%. Notably, these environmentally-friendly membrane nanocomposites can be used in water–oil separation applications successfully.
