Autor: Stoyan C. Russev, L Lakov, I Balchev, M Aleksandrova, G. V. Avdeev, Teodor Milenov, T Nurgaliev, I. Kostadinov, Evgenia Valcheva, K. Genkov

Using RF magnetron sputtering, we deposited Bi12TiO20 (BTO) thin films on various substrates (glass, quartz, stainless steel (SS304), (001) and (111) Si and sital-ceramics, Al and Cu foils). The films had a constant thickness of 1.3 μm. The as-depos

Characterization of hybrid fillers based on carbon black of different types obtained by impregnation

Autor: Petrunka Malinova, Falleh R. Al-Solamy, L. Lakov, Omar A. Al-Hartomy, Nikolay Dishovsky, Ahmed A. Al-Ghamdi

Publikováno v: Proceedings of the Institution of Mechanical Engineers, Part L: Journal of Materials: Design and Applications. 231:584-599

The paper presents the investigations on obtaining dual phase fillers with preset silica content running a successful impregnation of two completely different types of conventional carbon black with silicasol. The hybrid fillers studied were characte

Thiouracil modified activated carbon as a sorbent for some precious and heavy metal ions

Autor: P. Tzvetkova, L. Lakov, O. Peshev, P. Vassileva

Publikováno v: Journal of Porous Materials. 15:593-599

A new sorbent is prepared by modifying activated carbon obtained from apricot stones with 2-hydroxy-2-mercaptopyrimidine (2-thiouracil). The products have been characterized as to their surface area, pore volumes, content of the functional groups wit

Activated carbon sorbent with thioetheric sites—preparation and characterization

Autor: Galia Gentscheva, O. Peshev, P. Vassileva, Elisaveta Ivanova, P. Tzvetkova, L. Lakov

Publikováno v: Journal of Porous Materials. 15:331-334

An activated carbon sorbent containing thioetheric sites (ACTS) was prepared by modification of the activated carbon with 2,2′-thiodiethanol. The specific surface area, pore volume, concentration of oxygen-containing groups and sulfur content of th

Analytical characterization of a silica gel sorbent with thioetheric sites

Autor: Galia Gentscheva, O. Peshev, L. Lakov, P. Vassileva, Elisaveta Ivanova, P. Tzvetkova

Publikováno v: Microchimica Acta. 156:303-306

The sorption behavior of a newly synthesized silica gel sorbent with thioetheric sites (STS) towards microgram levels of Au(III), Pt(IV) and Pd(II) was studied. Au(III) is quantitatively (>95%) sorbed in the pH region of 1–9. The sorption of Pt(IV)

Organic–inorganic composites based on cyclotriphosphazene-cross-linked PHEMA networks

Autor: R. S. Velichkova, P. Mihailova, O. Peshev, I. Uzunov, L. Lakov, S. D. Ivanova, D. Christova, P. Tzvetkova

Publikováno v: Designed Monomers and Polymers. 6:11-21

Allyl-functionalized cyclotriphosphazenes (CPs) have been synthesized, characterized, and applied as cross-linking agents in the radical polymerization of 2-hydroxyethyl methacrylate (HEMA). The effect of the number of allylic substituents in the CP
