Radiation induced chain addition of allylbenzene to 1,4-dioxane has been studied by IR-, UV-, mass-, NMR- and ESR-spectrometry. Efficiency of the addition depends on the concentration of monomer and it has an optimum at C-monom<0.125M. Apparently, upper concentration limit of the reaction is caused by absorbed energy transfer on the molecule of monomer followed by energy deactivation. Radiation-chemical yields of the product are 12 and 31 molec./100 eV for 0.125M and 0.07M solution, respectively. The value of G(prod) is an evidence of chain character of the process.


Gamma-radiation initiated addition of allylbenzene to the morpholine
Nesterov, SV; Kucukyavuz, S; Önal, Ahmet Muhtar (Springer Science and Business Media LLC, 1999-10-01)
Radiation induced addition of allylbenzene to morpholine in liquid state was investigated by UV-, IR-spectroscopy and GS/mass spectrometry. Conversion of monomer depends on its initial concentration in the solution and this value is maximum for 0.05M solution. Radiation chemical yield of the product, G(prod), increases with concentration of allylbenzene and for 0.15M solution it is equal approximately 9.7 molec/100 eV. This value points on chain character of the process. Final product was identified by elec...

Studies of finer details in mass and charge distribution in fission leads to a better understanding of the fission process. Experimental determination of independent and cumulative yields using radiochemical techniques as well as mass spectrometers and fission product recoil separators form the basis of such studies. It has been established that closed shells as well as an even number of nucleons influence both mass and charge distributions. The magnitudes of these effects may be estimated from existing exp...
Quantum chemical treatment of cyanogen azide and its univalent and divalent ionic forms
Türker, Burhan Lemi; Atalar, Taner (Elsevier BV, 2008-05-30)
An explosive material, cyanogen azide (CN4) and its univalent and divalent anionic and cationic forms have been studied quantum chemically by using different theoretical approaches. In this study, the structures considered have been screened for their relative stabilities. Also, they have been investigated whether the charged forms play a role in the usual explosion process or any electrical charging during storage cause explosion. Various quantum chemical properties are obtained and discussed. It has been ...
Experimental determination of the dose deposition profile of a Sr-90 beta source
GAZA, R; Bulur, Enver; McKeever, S. W. S.; Soares, C. G. (Oxford University Press (OUP), 2006-09-01)
Three different methods for characterising the dose deposition profile of a Sr-90/Y-90 radioactive source are described: GAFChromic film dosimetry, Thermoluminescence (TL) and Optically Stimulated Luminescence (OSL). For the film measurements, GAFChromic film samples were stacked at different depths between polyethylene terephthalate (PET) foils. For TL, the thickness of a TLD-500 dosemeter was gradually reduced by polishing and the TL from chips of different thickness was used in conjunction with a mathema...
Sorption of radioactive cesium and barium ions onto solid humic acid
Celebi, O.; Kilikli, A.; ERTEN, HASAN NİYAZİ (Elsevier BV, 2009-09-15)
In this study, the sorption behavior of two important fission product radionuclides ((137)Cs and (140)Ba) onto sodium form of insolubilized humic acid (INaA) were investigated as a function of time, cation concentration and temperature, utilizing the radiotracer method. The sorption processes are well described by both Freundlich and Dubinin-Radushkevich type isotherms. Thermodynamic constants such as: free energy (Delta G(ads)), enthalpy (Delta H(ads)), entropy (Delta S(ads)) of adsorption were determined....
