In this study, nanocomposite materials based on titanium dioxide and polymethylene naphthalene sulfonate (PMNS) were investigated. The main objective was to evaluate the enhancement in ionic conductivity of the synthesized TiO₂/PMNS nanocomposites. Key structural parameters—including nanotube diameter, wall thickness, and pore spacing—were measured and statistically…

Keywords: anodizing, ammonium fluoride, water, pore diameter, naphthalene, polymethylene naphthalene sulfonate, electrical conductivity.

STUDY COLOUR REACTION OF CERIUM (III) WITH 2-[2-HYDROXYPHENILAZO]- NAPHTHALENE-1,8-DYHYDROXY-3,6-DISULPHONATE SODIUM AND BROMIDE CETYLTRIMETHYLAMMONIA

S.R.Gadjiyeva, F.E.Huseynov, M.T.Axundova, F.M.Chiraqov

Complex formation of cerium (III) with 2-[2-hydroxyphenilazo] naphthalene-1,8-dyhydroxy-3,6-disulphonate sodium (H3R) in the presence and the absence of bromide cetyltrimethylammonia has been studied. A parity of components is equal to 1:2 in homogeneous and to 1:2:2 in different ligand compounds. The influence of foreign ions to…

The radiolysis of Naphthalene, Fenantrene and benzo-pirilene and its water solutions under γ-radiation has been conducted. The decomposition of the above mentioned PAH and formation of products and the mechanism of radiolytic processes has been studied. It has been established that radiation-chemical yields of decomposition…
