Ambient light induced antibacterial action of curcumin/graphene nanomesh hybrids
(Royal Soc Chemistry, Cambridge, 2017)
Curcumin and its derivates are well-known for their different biological activities including antibacterial. On the other hand there are controversial reports concerning the antibacterial potential of graphene and, in ...
Structural and Electrical Properties of Ti Doped alpha-Fe2O3
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
In this work we have analyzed the effects of Ti doping on structural and electrical properties of alpha-Fe2O3. When the amount of added Ti (5 wt.% TiO2) was within the solubility degree and XRD, SEM and EDS analysis revealed ...
The Influence of Compaction Pressure on the Density and Electrical Properties of Cordierite-based Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
Due to its characteristics, cordierite, 2MgO center dot 2Al(2)O(3)center dot 5SiO(2), is a high-temperature ceramic material of a great scientific interest. Mechanical activation of the starting mixtures containing 5.00 ...

(Pensoft Publ, Sofia, 2013)
Investigations on the species composition and host range of aphids on ornamental greenhouse plants in Bulgaria was conducted over a period of five years, from 2008 to 2012. Twenty greenhouses, growing ornamentals for ...
Influence of Prolonged Sintering Time on Density and Electrical Properties of Isothermally Sintered Cordierite-based Ceramics
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
Mechanical activation is a commonly used and relatively fast and inexpensive procedure for sample preparation before the sintering process. Cordierite, a stoichiometric mixture of three different oxides (2MgO center dot ...
Pro-apoptotic and pro-differentiation induction by 8-quinolinecarboxaldehyde selenosemicarbazone and its Co(III) complex in human cancer cell lines
(Royal Soc Chemistry, Cambridge, 2016)
8-Quinolinecarboxaldehyde selenosemicarbazone (H8qasesc) and its octahedral Co(III) complex were characterized by single crystal X-ray diffraction analysis, spectroscopy methods and cyclic voltammetry. The antineoplastic ...
ZnTiO3 Ceramic Nanopowder Microstructure Changes During Compaction
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2013)
ZnTiO3 nanopowder as a constitutive component in compact production was primarily characterised. Scanning electron micrographs of as received powder were recorded. Mercury porosimetry and nitrogen adsorption were also ...
Fractal Corrections of BaTiO3-ceramic Sintering Parameters
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2014)
Morphology of ceramics grains and pores as well as Brownian character of particle dynamics inside ceramics specimen contributes to better understanding of the sintering process. BaTiO3-ceramics, studied in this paper, has ...
