Investigations of mechanical and flammability properties of hdpe reinforced flame retardant additives including antimony trioxide Antimon trioksit içeren alev geciktirici katkılı yüksek yoğunluklu polietilen’in mekanik ve alevgeciktiricilik özelliklerinin incelenmesi

Engin, Berk

ÖZETGünümüzde, Yüksek Yoğunluklu Polietilen (HDPE)’nin, kimyasal direnç, kolay üretim tekniği, termal ve elektriksel yalıtımı, yüksek mukavemet/yoğunluk oranı gibi özelliklere sahip olmasından olayı yaygın bir kullanım alanı mevcuttur. Ancak HDPE, içerdiği karbon ve hidrojenden dolayı son derece yanıcıdır, HDPE'nin yangına karşı dayanıklılığını geliştirmek için uygulanabilecek bazı Alev Geciktirici takviye işlemlerivardır. Bu çalışmada Antimon Trioksit (Sb2O3) içeren iki farklı tipte ticari AlevGeciktirici masterbatch belli oranlarda HDPE matrise takviye edilmiştir. Bu şekilde HDPE matris örne ...Daha fazlası

Neurovascular Co-Cultures in hydrogel building blocks Hidrojel bloklarda nörovasküler ko-kültür çalışmaları

Ersoy, Fulya

ABSTRACTCreating a tissue or an organ model is the most emerging field of the biomedical research for the last decades. Three-dimensional scaffolds that will mimic the extracellular matrix were designed and used in various applications to investigate the behavior of cells.In this study, both the synthesis of the polymer and the fabrication of three-dimensional hydrogel scaffolds were practiced. Gelatin methacrylate (GelMA) was synthesized prior to photopolymerization of the hydrogel. A novel scaffold fabrication device was designed and manufactured. This device allowed us fabricating computer ...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

Carbon based heating elements and their practical applications Karbon bazlı ısıtma elemanları ve pratik uygulamaları

Yavaş, Ahmet

ABSTRACTCarbonaceous materials have attracted a tremendous amount of attention during the last decades due to their outstanding properties for a variety of applications. Among them, carbon fibers are state of the art materials with excellent physical, mechanical, electrical, thermal and chemical properties. Especially the thermal and electrical properties of carbon fibers combined with other prominent characteristics enable them to be employed as an effective heating element. Regarding to this motivation, in this study, it is mainly aimed to fabricate carbon fiber based heating elements and to ...Daha fazlası
