Frequent use of bisphenol-a polycarbonate in daily life results with a huge amount of polycarbonate waste. The proper utilization of this waste would be an environmental friendly approach. As polymeric materials are candidate materials for radioactive waste embedding, having an aromatic structure within the main chain, the bisphenol-a polycarbonate is a candidate material to be used as an embedding matrix for the confinement of low and intermediate level radioactive waste. This possibility would partly solve the problem of huge amount of waste generated due to the usage of polycarbonate.

Possible use of EPDM in radioactive waste disposal: Long term low dose rate and short term high dose rate irradiation in aquatic and atmospheric environment
Hacioglu, Firat; Ozdemir, Tonguc; Cavdar, Seda; Usanmaz, Ali (2013-02-01)
In this study, changes in the properties of ethylene propylene diene terpolymer (EPDM) irradiated with different dose rates in ambient atmosphere and aqueous environment were investigated. Irradiations were carried out both with low dose and high dose rate irradiation sources. EPDM samples which were differentiated from each other by peroxide type and 5-ethylidene 2-norbornene (ENB) contents were used. Long term low dose rate irradiations were carried out for the duration of up to 2.5 years (total dose of 1...
Development of rare earth-free negative electrode materials for NiMH batteries
Onur Şahin, Ezgi; Öztürk, Tayfur; Department of Metallurgical and Materials Engineering (2016)
Ni/MH battery negative electrodes normally make use of rare earth AB5 compounds. Development of rare earth-free negative electrode materials for Ni/MH batteries is desirable so as to lower the cost, and widen the availability. Although there are a number of alternatives, of these AB2 alloys are particularly attractive, as they offer better capacities than AB5. A major problem in this group of alloys is that they are difficult to activate, i.e. they require a large number of cycles before they could reach th...
Degradation of poly(carbonate urethane) by gamma irradiation
Ozdemir, T.; Usanmaz, Ali (Elsevier BV, 2007-06-01)
Poly(carbonate urethane) (PCU), is a valuable commercial engineering polymer. In order to understand the possible use of PCU in radioactive waste management as a solidifying agent or as a disposal container, radiation stability of the PCU is studied by Co-60 gamma irradiations at two different dose rates of 1540 and 82.8 Gy/h. The total dose of irradiation was up to 6.24 MGy. Degradation nature was tested by studying the changes in mechanical and thermal properties with rate and total dose of irradiation. U...
Preparation and characterization of conductive polymer composites, and their assessment for electromagnetic interference shielding materials and capacitors
Köysüren, Özcan; Bayram, Göknur; Department of Chemical Engineering (2008)
The aim of this study was to improve electrical properties of conductive polymer composites. For this purpose, various studies were performed using different materials in this dissertation. In order to investigate the effect of alternative composite preparation methods on electrical conductivity, nylon 6/carbon black systems were prepared by both in-situ polymerization and melt-compounding techniques. When compared with melt compounding, in-situ polymerization method provided enhancement in electrical condu...
