Dielectrophoretically alignment of MWCNTs in poly(ethylene glycol) dimethacrylate for neural guiding of PC12 cells PC12 hücrelerinin nöral yönlendirilmesi için ÇDKNT'lerin poli(etilen glikol) dimetakrilat içinde dielektroforetik olarak hizalanması

Seven, Fikri

ABSTRACTPC12 cell line is widely used as an in vitro model for neuronal diseases and studying cell differentiation behavior. The cell line has the ability to differentiate into neuronlike cells in the presence of nerve growth factor (NGF), resulting in neural extensions called dendrites and axons. Cell patterning is widely used in applications such as neuron network formation, tissue engineering, and cell based biosensors. In this study, the effect of randomly distributed and aligned multi walled carbon nanotubes (MWCNTs) in poly(ethylene glycol) dimethacrylate (PEGDMA) on PC12 cell neuronal d ...Daha fazlası

Gölcez, Tansu

ABSTRACTNervous system diseases occupy a very large place among diseases without treatment today. One of the major challenges in nervous system diseases is achieving functional connection between nerve cells. A neuronal network is a very complex structure consisting of connections between neuronal cells through dendrites and axons. In this context, a human brain can be described as a complex neuron network. Platforms capable of creating a neuronal network have the potential to be used in a variety offields, such as modeling neuron-related diseases, finding new treatments, building biological c ...Daha fazlası

Economic analysis of water storage by rainwater harvesting technique at Izmir Katip Celebi İzmir Katip Çelebi Üniversitesi yağmur suyu hasadı tekniği ile su depolanmasının ekonomik analizi

Taşçı, Hadya

ABSTRACTIn this thesis, the economic analysis of water storage by rainwater harvesting technique at Izmir Katip Celebi university (IKCU) was studied. The data from the flowmeters, which were installed in the men-women toilets in the central classrooms, were recorded, and the catchment area was calculated. According to the data, the amount of rainwater to be collected can meet the water demand in the toilets flushing. Theeconomic analysis of the rainwater harvesting (RWH) was made for three scenarios their difference in initial cost by the calculations of the payback period (PBP), the net prese ...Daha fazlası

Integration and testing of the RFID-enabled smart factory RFID-etkin akıllı fabrikanın entegrasyonu ve test edilmesi

Akdağ, İsmail

ABSTRACTWith the development of technology, factory needs in supply chain management from production to customers have started to change. Factories have started to frequently benefit from communication systems in product tracking, warehouse stock control and supply chain management. Radio Frequency Identification (RFID) system is one of the main components of IoT technologies, where data transfer occurs wirelessly and flexibly, instead of traditional tracking and monitoring methods. RFID systems, which are automatic identification systems such as barcode systems used for the last 30 years, off ...Daha fazlası

Growth of zinc oxide nanostructures on carbon fibers: Production, characterization and photocatalytic properties Çinko oksit nanoyapıların karbon fiber üzerinde büyütülmesi: Üretimi, karakterizasyonu ve fotokatalitik özellikleri

Doğan Tunç, Irmak

ÖZETSon yıllarda, karbon fiber üzerine büyütülmüş çinko oksit nano yapıları, üstünyapısal, elektriksel ve optik özellikle dolayısı ile yoğun olarak çalışılmaktadır. ZnO, geniş band aralığı (3.37 eV) nedeniyle morötesi ışık altında aktive olabilen bir yarı iletken fotokatalizördür. Ancak, çinko oksidin karbon temelli malzemeler üzerinde büyütülmesi veya yapısına metallerin katkılanması ile yasak band aralığının daraltılması ve görünür bölge ışığı altında aktive edilmesi sağlanabilir.
