Synthesis and characterization of titanosilicate ets-10 for potential photovoltaic applications
Galioğlu, Sezin; Akata Kurç, Burcu; Department of Micro and Nanotechnology (2010)
Different kinds of nanoparticles are widely used in optoelectronic and photovoltaic applications to harvest light to increase efficiency of devices. ETS-10, which is a synthetic microporous material consisting of –Ti-O-Ti-O-Ti- wires that run in the crystal in a and b directions, has been of interest in such applications due to its unique properties. In the current study, the synthesis conditions of ETS-10 were investigated in order to obtain pure ETS-10 crystals with the desired morphology. For this purpos...
Synthesis and characterization of hydrothermally grown potassium titanate nanowires
KAPUSUZ, Derya; Kalay, Yunus Eren; Park, Jongee; Öztürk, Abdullah (2015-06-01)
Potassium titanate (KT) nanowires were synthesized by a one-step hydrothermal reaction between TiO2 and aqueous KOH solution. The effects of KOH concentration and reaction time on hydrothermal formation and KT nanowire growth were investigated. The nanowire growth mechanism was elucidated using a combined study of powder X-ray diffraction, and scanning and transmission electron microscopy. The results revealed that hydrothermal growth was initiated by the formation of amorphous-like Ti-O-K sheets in anatase...
Synthesis and functionalization of graphene oxide nanocomposites for anticancer drug delivery
Kamal Mohammed Ahmed Hassan, Heba; Evis, Zafer; Tezcaner, Ayşen; Department of Biomedical Engineering (2022-6-27)
Graphene, graphene quantum dots (GQDs) their derivatives and gold nanoparticles (AuNPs), all have a wide range of applications in biomedical applications, particularly anticancer drug delivery, due to their large surface area, chemical and mechanical stability, and good biocompatibility. The first goal of this research is to improve the chemistry and solubility of rGO by doping it with boron and decorating it with AuNPs (Au-B-rGO), as well as to improve the loading efficiency of the anticancer drug doxorubi...
Synthesis and characterization of benzodithiophene containing conjugated polymers for organic bulk heterojunction solar cells
Taşkaya Aslan, Sultan; Çırpan, Ali; Department of Chemistry (2022-8-2)
Bulk heterojunction organic solar cells (BHJ-OSCs) have drawn attention as a renewable energy source due to their flexibility, lightweight and low cost in large-area applications. Besides the design of novel polymeric materials with different building blocks, the device architectures of the solar cells have been improved significantly to increase the power conversion efficiency (PCE) of solution-processed OSCs over the last years. Up to now, PCE for single layer BHJ-OSCs has reached 18%, and high performanc...
Synthesis and Characterization of Multifunctional GdB3O6/Ca10(PO4)6(OH)2 Core/Shell Particles for Biomedical Applications
Uzun, Mehmet Burak; Yılmaz, Ayşen; Department of Chemistry (2023-1-06)
Multifunctional particles with multiple properties are used in biomedical applications for cancer treatment. With the recently developing technology, particles with photoluminescent properties can perform real-time imaging. In this study, Ce3+/Tb3+ co-doped, Eu3+ doped GdB3O6 particles were synthesized, coated with hydroxyapatite (HAP) and polyethylene glycol (PEG). Then, particles were loaded with doxorubicin. Ce3+/Tb3+ co-doped and Eu3+ doped GdB3O6 particles were synthesized by the sol-gel process using ...
