Radiation grafting of various water-soluble monomers on ultra-high molecular weight polyethylene powder: Part I. Grafting conditions and grafting yield
Aydinli, B; Tincer, T (Elsevier BV, 2001-02-01)
Monomers of some water-soluble polymers; acrylic acid, methacrylic acid, acrylamide, N, N-dimethyl acrylamide and 1-vinyl-2 pyrrolidone, were grafted on ultra-high molecular weight polyethylene (UHMWPE) powders by a direct grafting method in an aqueous medium in air. Inhibition of homopolymerisation was achieved by adding various concentrations of Fe2+ or Cu2+ ions. It was found that the degree of grafting increases linearly with dose till a gelation state is reached, and varies between 40 and 12% depending...
ESR dating of calcrete nodules from Bala, Ankara (Turkey): Preliminary results
Kucukuysal, Ceren; Engin, Birol; Günal Türkmenoğlu, Asuman; Aydas, Canan (Elsevier BV, 2011-02-01)
The age of two calcrete nodules (C1 and C2) from the Bala section in the region of Ankara, Turkey, is determined by the Electron Spin Resonance (ESR) method. Three radiation-induced ESR signals at g=2.0056 (A signal), g=2.0006 (C signal) and g=2.0038 (broad signal, BL) were observed. The broad signal (BL) intensity was used as a dating signal. The properties of this dating signal are described in this manuscript. The calcrete nodules were irradiated with a Co-60 gamma source and measured with an ESR spectro...
Hydrophobicity of chalcopyrite with dithiophosphate and dithiophosphinate in electrochemically controlled condition
Guler, T; Hicyilmaz, C (Elsevier BV, 2004-03-18)
The degree of hydrophobicity of chalcopyrite was determined by contact angle measurements on polished chalcopyrite surface in electrochemically controlled conditions. Results have shown that the increase in solution pH adversely affect hydrophobicity due to heavy surface oxidation. Maximum contact angles were measured at moderately oxidizing potentials, which proposed that slight oxidation is necessary for a hydrophobic chalcopyrite surface. Sodium diisobutyl dithiophosphinate (DTPI) displayed better result...

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...
