Abstract – Polietilenglicol-containing maleate interaction with phosphorus (V) oxochloryde has led to formation of a novel surface-active monomer with the terminal phosphate group. The polymerization ability of the synthesized monomer was studied in the processes of binary and tertiary copolymerization with peroxide-containing monomer 5-Tertbutylperoxy- 5-methyl-2-hexene-3-yne (VEP) and N-vinyl pyrrolidone to form a surface-active copolymers. The possibility of using these copolymers as surface-active macroinitiators of emulsion polymerization of styrene and composites, to create polymeric substrates for tissue engineering was shown.
Recombination luminescence in LaPO4-Eu and LaPO4-Pr nanoparticles
(Видавництво Львівської політехніки, 2012) Vistovskyy, V.; Malyy, T.; Voloshinovskii, A.; Getkin, A.; Shapoval, O.; Zaichenko, A.; Mitina, N.
The luminescence properties of LaPO4-Eu and LaPO4-Pr nanoparticles with various sizes (8–50 nm) are studied upon the excitation by VUV and X-ray quanta. The dependences of luminescence intensity on nanoparticle size for nanoparticles LaPO4-Pr and LaPO4-Eu possessing, respectively, by the electron and hole recombination luminescence at the excitation by quanta of various energies are discussed.
Structural and magnetic characterization of functional surface coated maghemite nanoparticles
(Видавництво Львівської політехніки, 2012) Demchenko, P.; Mitina, N.; Zaichenko, A.; Nedelko, N.; Lewińska, S.; Ślawska-Waniewska, A.; Dłużewski, P.; Bilska, M.; Ubizskii, S.
Nanoparticles composed of magnetic γ-Fe2O3 core and organic shell were synthesized via template synthesis in the presence of functional oligoperoxide surfactants and further graft-polymerization initiated from their surface. X-ray diffraction (XRD), transmission electron microscopy (TEM) and magnetic measurements (PPMS) were used to characterize the obtained magnetic system of core-shell nanoparticles. XRD results confirm the existence of γ-Fe2O3 phase as well as show an average diameter of nanoparticles around 10 nm. The obtained particles are superparamagnetic at the room temperature. Magnetic measurements indicate also sufficiently strong dipolar interparticle interactions at low temperatures.
