Nonlinear properties of antimony-doped BaTiO3 ceramics
(Springer Heidelberg, Heidelberg, 2015)
Barium titanate nanopowders doped with various concentrations of antimony were synthesized by polymeric precursors method based on modified Pechini process. Obtained powders were pressed and sintered at 1,573 K for 8 h. ...
Characterisation of antioxidants in photosynthetic and non-photosynthetic leaf tissues of variegated Pelargonium zonale plants
(Wiley, Hoboken, 2016)
Hydrogen peroxide is an important signalling molecule, involved in regulation of numerous metabolic processes in plants. The most important sources of H2O2 in photosynthetically active cells are chloroplasts and peroxisomes. ...
Thermal behaviour of the TiO2-based gels obtained by microwave-assisted sol-gel method
(Springer, Dordrecht, 2017)
In order to establish the influence of the preparation method on thermal behaviour of gels obtained by the sol-gel and microwave-assisted sol-gel methods, a comparative thermal analysis study was conducted by the ...
Dielectric properties, complex impedance and electrical conductivity of Fe2TiO5 nanopowder compacts and bulk samples at elevated temperatures
(Springer, Dordrecht, 2017)
In this work we have investigated changes in dielectric properties, electrical conductivity and complex impedance of Fe2TiO5 nanopowder compacts and bulk samples as a function of elevated temperature (room to 423 K compacts, ...
In vitro antibiofilm activity of the freshwater bryozoan Hyalinella punctata: a case study of Pseudomonas aeruginosa PAO1
(Taylor & Francis Ltd, Abingdon, 2016)
The antibiofilm and possible antiquorum sensing effects against the strain Pseudomonas aeruginosa PAO1 of five crude extracts of the freshwater bryozoan Hyalinella punctata (Hancock, 1850) were evaluated in vitro for the ...
An insight into antimicrobial activity of the freshwater bryozoan Pectinatella magnifica
(Taylor & Francis Ltd, Abingdon, 2016)
The antimicrobial activity of five crude extracts of the freshwater bryozoan Pectinatella magnifica (Leidy, 1851) was evaluated in vitro for the first time. P. magnifica acetone extract exhibited the highest antibacterial ...
Boom-bust like dynamics of invasive black bullhead (Ameiurus melas) in Lake Sava (Serbia)
(Wiley, Hoboken, 2019)
The life-history traits and population dynamics of the black bullhead Ameiurus melas (Rafinesque) were studied monthly from August 2009 to December 2012 in Lake Sava in Belgrade (Serbia). This period included a mass mortality ...
An insight into anti-biofilm and anti-quorum sensing activities of the selected anthocyanidins: the case study of Pseudomonas aeruginosa PAO1
(Taylor & Francis Ltd, Abingdon, 2017)
Anti-biofilm activity of three anthocyanidins (pelargonidin, cyanidin and delphinidin) was evaluated for the first time at in vitro conditions. All the compounds reduced the formation of Pseudomonas aeruginosa PAO1 biofilm ...
Anti-cancer effects of wedelolactone: interactions with copper and subcellular localization
(Royal Soc Chemistry, Cambridge, 2018)
Wedelactone (WL), a plant polyphenolic derivative of coumestan, represents a promising anti-cancer agent. The underlying mechanisms of its action are not fully understood and appear to involve interplay with copper ions. ...
Evaluation of genotoxic potential of avarol, avarone, and its methoxy and methylamino derivatives in prokaryotic and eukaryotic test models
(Taylor & Francis Ltd, Abingdon, 2019)
In this study, mutagenic and genotoxic potential of anti-tumor compounds avarol, avarone, and its derivatives 3 '-methoxyavarone, 4 '-(methylamino)avarone and 3 '-(methylamino)avarone was evaluated and compared to cytostatics ...
