Generation, storage and delivery of singlet oxygen by a multifunctional agent
(Bilkent University, 2017-04)Photodynamic therapy (PDT) relies on thephoto sensitized generation of sin- glet oxygen (by consuming dissolved oxygen) within tumortissues whose oxygen level is already low enough to make this treatment self-limiting. In ... -
Iron oxide/silica core-shell nanoparticles as rechargeable sources of singlet oxygen for synthetic applications
(Bilkent University, 2017-04)In the rapidly developing world ofsynthetic chemistry, there is aconstant need for high-efficient catalyst. Besides this, reusable and easily removable catalysts are highly desired to reduce costs for environmentally ... -
Synthesis and characterization of Bodipy-derived singlet oxygen sensor
(Bilkent University, 2017-02)Singlet oxygen is a biochemically produced reactive species, which can trigger various cellular responses. It is also produced by photosensitization by the intermediacy of photosensitizer therapy of cancer. Real-time imaging ... -

Utilization of reducible mixed metal oxides as promoters for the enhancement of sulfur regeneration in nsr catalysts
(Bilkent University, 2016-08)Pt functionalized binary, ternary, and quaternary oxides (e.g. Pt/BaO/CeO2/ZrO2/Al2O3) were synthesized by wetness impregnation method and characterized by X-ray Diffraction (XRD), Brunauer–Emmett–Teller (BET) surface area ... -
Metal dicyanamides as solid adsorbents for CO2/N2 separation and efficient water oxidation catalysts
(Bilkent University, 2016-08)The demand for the energy has been increasing exponentially and it is expected to double by 2050 as a result of population increase in the world. The fact that fossil-based fuels are limited and they releases CO2 gas, which ... -
Designing novel DENOx catalysts with a wide thermal operational window
(Bilkent University, 2016-06)The main objective of this study is to design novel DeNOx catalyst to widen the operational temperature range of exhaust emission control systems. For this purpose, single and multi NOx-storage domains (e.g. K2O, BaO) were ... -
Identification of NO subscript x species adsorbed on cobalt(II)-supported zirconia and sulfated zirconia and investigation of their reactivity toward methane
(Bilkent University, 2002)In the period between the eleventh and the thirteenth centuries migrations from the Frankish heartland into different parts of Europe created a situation in which we see the “Europeanization of Europe”. In the course of ... -
