Development of D -type fiber optic sensors for detection of refractive index variation in evanescent wave field /
Güleryüz, Burcu; Durucan, Caner; Aslan, Mustafa M.; Department of Metallurgical and Materials Engineering (2014)
The purpose of this study is to design, construct, develop and test D-type multimode fiber optic (F/O) sensors based on evanescent wave field sensing. A comprehensive work has been performed both theoretically and experimentally using a geometrical modification approach to improve the sensors response in different manners for detecting the refractive index (RI) variations and bio-molecular interactions in aqueous environment. In this study, the D-type F/O sensors performance was improved utilizing optical w...

Development of cathode materials for li-ion batteries by sputter deposition
Erdoğan, Erdem Erkin; Aydınol, Mehmet Kadri; Department of Metallurgical and Materials Engineering (2022-2-10)
The electrochemical performance of Li-ion batteries depends mostly on the cathode material. Cobalt has a huge impact on electrochemical properties and is widely used in cathode materials, but due to its toxicity and cost, recent research is focused on reducing the amount of cobalt in cathode materials. In this study, cathode active materials are produced by magnetron sputtering to obtain the optimum amount of cobalt while optimizing the electrochemical properties. Pechini sol-gel method is used to produce p...
Development of amperometric cholinesterase biosensors based on a conducting polymer for detection of anti-dementia drugs and pesticides
Turan, Janset; Toppare, Levent Kamil; Özkan, Necati; Department of Polymer Science and Technology (2016)
Cholinesterase enzymes are considered as one of the most important enzymes in living organisms and they are targeted by many inhibitors. Cholinesterase inhibitors are potentially toxic however they also have certain applications as treatment of dementia and Alzheimer’s diseases. These inhibitors can bind the active side of the cholinesterase enzymes forming stable complexes. This inhibitory effect can be used to construct fast and sensitive detection system. Also, conducting polymers are known to be well su...
Development of helical tubular reactor for hydrogen producing photosynthetic bacteria
Sarı, Süleyman; Eroğlu, İnci; Department of Biotechnology (2007)
Photobiological hydrogen production from organic materials occurs with the help of illumination and under aerobic conditions within photobioreactors. Novel designs are needed in order to increase the light conversion efficiency and to improve the biological hydrogen production. In this thesis, purple non sulfur bacteria Rhodobacter sphaeroides O.U. 001 was employed as the hydrogen producing microorganism. Two different types of photobioreactors, namely oscillatory helical photobioreactor and recycling helic...
