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. Bu bilgiler ışığında, yapılacak çalışmada, çinko oksit nanotellerin, karbon fiber üzerinde hidrotermal yöntem il ...Daha fazlası

Effect of Coating Material on High Temperature Oxidation of Inconel 738LC Superalloy

Simge AVCI

Inconel 738LC alaşımı nikel bazlı bir süperalaşımdır ve genellikle gaz türbinlerinde, türbin nozullerinde ve türbin bıçaklarında kullanılmaktadır. Gaz türbin motoru bileşenlerinde kullanımı yaygın olan Inconel 738LC çalışma ortam koşulları sebebi ile yüksek sıcaklık ile birlikte yüksek korozyona da maruz kalmaktadır. Bu sebeple, bu malzemenin yüksek sıcaklık mukavemet değeri ve yüksek sıcaklık oksidasyon direnci büyük önem taşımaktadır. Bu çalışmada karbon elementinin Inconel 738 alaşımında mekanik ve mikroyapısal etkileri incelenmiştir. Oda sıcaklığında ve iki farklı yüksek sıcaklıktak ...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

Investigation of the Effect of Electrode Material on Antibacterial Activity in Plasma Treatment with Dielectric Barrier Discharge

Merve Gül

Plasma is an ionized gas generated under an electric field that contains photons, free electrons, ions, free radicals, and reactive oxygen/nitrogen species (RONS). Cold atmospheric plasma (CAP) is generated in the cold form under a high electric field at atmospheric pressure. CAP is generated using two methods, Dielectric Barrier Discharge (DBD) and plasma jet. In the DBD method, the electrode configuration, shape, material, and substance from which the dielectric barrier is made are important. Beyond the electrode design and geometry, the barrier and electrode materials can also impact the re ...Daha fazlası
