Design and implementation of a mems based spiral channel dielectrophoretic separator for cytometry applications
Yılmaz, Gürkan; Külah, Haluk; Department of Electrical and Electronics Engineering (2010)
This thesis reports design and implementation of a MEMS based spiral channel dielectrophoretic separator for cytometry applications. Main objective of the thesis is to separate leukemia cells from healthy leukocytes with respect to the differences in their dielectric properties. A novel MEMS based dielectrophoretic separator with spiral channels and concentric 3D electrodes has been proposed. The proposed geometry decreased the footprint, which reduces the device cost, without degrading the separation and q...
Microwave assisted solid state synthesis of rare earth ions doped LaBO3, YBO3 and GdBO3, their characterizations and investigations of luminiscence properties
Severoğlu, Metehan; Yılmaz, Ayşen; Esentürk, Okan; Department of Chemistry (2016)
LnBO3 are notable host materials to doped with Rare Earth Element (REE) to achieve strong luminescence. Therefore, it attracts great attention of scientist for many decades with promising applications in many field such as affordable Light Emitting diode (LED) devices. This research covers the synthesis of undoped lanthanum, gadolinium, and yttrium orthoborates and dysprosium, terbium and samarium ions doped LnBO3 (Ln: La, Gd, Y) by microwave assisted solid state synthesis method to investigate the effect o...
Symbol space and meaning in hittite architecture
Onurlu, Sema; Güven, Suna Naziyet; Department of History of Architecture (2004)
The importance of the Hittites derives from the fact that they were an organized central power extending over a large territory within which a number of societies maintained their language, culture and traditions. The archaeological findings of Hattusha, the Hittite capital reveal that the city had reached its maximum limits during the Great Kingdom period and the most magnificient and monumental buildings of the city are dated to this period. Yazilikaya, the open air sanctuary which reached to its final fo...
Cobalt ferrite supported platinum nanoparticles: Superb catalytic activity and outstanding reusability in hydrogen generation from the hydrolysis of ammonia borane
Akbayrak, Serdar; Özkar, Saim (2021-08-15)
In this work, platinum(0) nanoparticles are deposited on the surface of magnetic cobalt ferrite forming magnetically separable Pt-0/CoFe2O4 nanoparticles, which are efficient catalysts in H-2 generation from the hydrolysis of ammonia borane. Catalytic activity of Pt-0/CoFe2O4 nanoparticles decreases with the increasing platinum loading, parallel to the average particle size. Pt-0/CoFe2O4 (0.23% wt. Pt) nanoparticles have an average diameter of 2.30 +/- 0.47 nm and show an extraordinary turnover frequency of...
Estimation of carbon dioxide flux in shallow lakes in Turkey
Kalvenas, Jennifer; Beklioğlu, Meryem; Department of Biology (2014)
The role of Turkish shallow lakes as a sink or source of carbon from 44 shallow lakes sampled once from 2006 – 2012 over six degrees of latitude is analyzed in terms of spatial resolution. Two of the lakes (Eymir and Mogan) were sampled over the spring, summer, and fall seasons from 2006 – 2010 under dry and wet periods and analyzed for temporal resolution. An equation using pH, specific conductivity, wind speed, temperature, and acid neutralizing capacity (ANC) was used to determine CO2 fluxes (Trolle et a...
