In this study, the radiation degradation/modification of the vulcanized EPDM and the effects of dose rate, peroxide type/content in vulcanization system and ENB content of EPDM were studied to investigate the change in the extend of the modification/degradation of the mechanical properties of vulcanized EPDM via gamma irradiation. In addition, thermal, dynamic mechanical, ATR-FTIR, TGA, TGA-FTIR tests were carried out to understand the change of properties of vulcanized EPDM via irradiation. Samples were irradiated with two different dose rates of 1280 and 64.6 Gy/h. Total dose of irradiation was up to 184 kGy. The FTIR spectral analysis showed structural changes of EPDM via irradiation. It was observed that the dose rate changed the mechanical properties with different extends. The change of ENB content of EPDM and peroxide type and content in vulcanization system affect extend of the modification/degradation of the EPDM's properties.

Degradation of poly(bisphenol-a-epichlorohydrin) by gamma irradiation
Ozdemir, Tonguc; Usanmaz, Ali (Elsevier BV, 2008-06-01)
In this study, radiation stability of poly(bisphenol-a-epichloroliydrin) (PBEH) was studied via gamma irradiations at two different dose rates of 1540 and 82.8 Gy/h, in order to understand the possible use of PBEH in radioactive waste management as a solidifying agent. The total dose of irradiation was up to 2150kGy. Degradation nature was tested by studying the changes in mechanical and thermal properties with the change of dose rate and total dose of irradiation. Tensile strength at yield was increased fi...
Co-60 gamma irradiation influences on physical, chemical and electrical characteristics of HfO2/Si thin films
KAYA, ŞENOL; Yıldız, İlker; LÖK, RAMAZAN; YILMAZ, ERCAN (Elsevier BV, 2018-09-01)
Co-60 gamma irradiation effects on physical, chemical and electrical characteristics of HfO2/Si thin films have been investigated in details. The variations on the crystallographic structure and surface morphology of the films under irradiation exposures were characterized by using X-ray diffractions (XRD) and Atomic Force Microscopy (AFM) measurements. The irradiation influences on the electrochemical structure of the films were analyzed by X-ray photoelectron spectroscopy (XPS) for various depths of the H...
Treatment of opium alkaloid containing wastewater in sequencing batch reactor (SBR)-Effect of gamma irradiation
Bural, Cavit B.; Demirer, Goksel N.; Kantoglu, Omer; Dilek, Filiz Bengü (Elsevier BV, 2010-04-01)
Aerobic biological treatment of opium alkaloid containing wastewater as well as the effect of gamma irradiation as pre-treatment was investigated. Biodegradability of raw wastewater was assessed in aerobic batch reactors and was found highly biodegradable (83-90% degradation). The effect of irradiation (40 and 140 kGy) on biodegradability was also evaluated in terms of BOD5/COD values and results revealed that irradiation imparted no further enhancement in the biodegradability. Despite the highly biodegrada...
Synthesis and characterization of hydrogels from allyl methacrylate and acrylamide copolymer
Ayazoğlu, Neslihan; Usanmaz, Ali; Keskin, Selda; Department of Polymer Science and Technology (2011)
Acrylamide based hydrogels were synthesized through copolymerization reaction of allyl methacrylate with acrylamide. Copolymerization reactions were carried out with solution polymerization in tetrahydrofuran by using α-α-azoisobutyronitrile as an initiator at 60 0 C. Three copolymer compositions were studied having 5, 15, 25 molar percentage of allyl methacrylate as feed concentrations. The synthesized copolymers were characterized by FTIR, NMR, DSC, TGA and GPC. 1H-NMR spectra were used to confirm the che...
Correlations of the thermodynamic quantities with the frequency shifts of a lattice mode close to the I-II transition in NH4Br
Yurtseven, Hasan Hamit (Elsevier BV, 2010-06-01)
We correlate here the specific heat C-p with the frequency shifts (1/V) (partial derivative V/partial derivative T) and the thermal expansivity alpha(p) with the (1/v) (partial derivative V/partial derivative P)(T) close to the I-II transition in NH4Br. This correlation is performed for the Raman mode of vs (140 cm(-1)) using the molar volume data for NH4Br. It is shown here that spectroscopic modifications of the Pippard relations are applied satisfactorily to the I-II phase transition by using a lattice m...
