Bu çalışmada, Edirne-Enez bölgesinden alınan Ca-montmorillonit türü kil numunesine kısa zincirli amin grubundan dimetilamonyum hidroklorür adsorplanarak elde edilen kil-organik kompleksinin dielektrik parametreleri belirlenmiştir. Bu işlemde, numunenin 5Hz-13MHz aralığında ölçülen admitans değerlerinden hesaplanan kompleks geçirgenliğin reel ve sanal kısımları elektrik modülü formalizminde ifade edilmişitir. Bu parametrelerin belirlenmesinde, yukarıdaki frekans bölgesinde etkili olan yönelimli ve arayüzeysel kutuplanma mekanizmalarını en genel biçimde temsil eden teorik bağıntı (Havriliak-Negami ve güç yasalı iletkenlik bağıntılarının toplamı olan) deneysel verilere uydurulmuştur.
Dimetilamonyum-montmorillonit yönelimli kutuplanma arayüzeysel kutup-lanma elektrik modülü formalizmi
In this study, we have determined the dielectric properties of the clayorganic complex obtained by adsorption of a short chained amine, namely dimethylammonium hydrochloride, on a Ca-montmorillonite type clay sample picked from Edirne-Enez area. Complex electrical permittivity of the sample are calculated from the admittance values measured in the 5Hz-13MHz range, and these permittivities are expressed using electric modulus formalism. The dielectrical parameters are determined by fitting a theoretical expression, containing the orientational (Havriliak-Negami) and interfacial (conductivity with power law) polarization mechanisms effective in the above frequency region, to the experimental data.

Selcuk University Journal of Science Faculty accepts articles in Turkish and English with original results in basic sciences and other applied sciences. The journal may also include compilations containing current innovations.
It was first published in 1981 as "S.Ü. Fen-Edebiyat Fakültesi Dergisi" and was published under this name until 1984 (Number 1-4).
In 1984, its name was changed to "S.Ü. Fen-Edeb. Fak. Fen Dergisi" and it was published under this name as of the 5th issue.
When the Faculty of Letters and Sciences was separated into the Faculty of Science and the Faculty of Letters with the decision of the Council of Ministers numbered 2008/4344 published in the Official Gazette dated 3 December 2008 and numbered 27073, it has been published as "Selcuk University Journal of Science Faculty" since 2009.
It has been scanned in DergiPark since 2016.
