The characterization of the barium titanate ceramic powders prepared by the Pechini type reaction route and mechanically assisted synthesis
(Elsevier Sci Ltd, Oxford, 2010)
BaTiO3 ceramic powders were prepared by a complex method based on the Pechini type reaction route and mechanically assisted synthesis. In both ways BaTiO3 ceramics were sintered after 120 min on 1300 degrees C without ...
Dielectric and relaxor behavior of BaBi4Ti4O15 ceramics
(Elsevier Science Sa, Lausanne, 2010)
Barium bismuth titanate BaBi4Ti4O15 (BBiT) ceramics have been prepared using non-conventional solid-state reaction route based on mechanochemical synthesis during intensive milling. The X-ray diffraction method was used ...
Immobilization of hexavalent chromium by fly ash-based geopolymers
(Elsevier Sci Ltd, Oxford, 2017)
In this paper the immobilization of hexavalent chromium (Cr (VI)) by fly ash (FA)-based geopolymers was investigated, depending on FA characteristics, mechanical activation of FA, geopolymer synthesis conditions and ...
Flooding modifies the genotoxic effects of pollution on a worm, a mussel and two fish species from the Sava River
(Elsevier, Amsterdam, 2016)
Extreme hydrological events, such as water scarcity and flooding, can modify the effect of other stressors present in aquatic environment, which could result in the significant changes in the ecosystem functioning. Presence ...
Dielectric and ferroelectric properties of Ho-doped BiFeO3 nanopowders across the structural phase transition
(Elsevier Sci Ltd, Oxford, 2017)
We have studied Ho-doped BiFeO3 nanopowders (Bi1-xHoxFeO3, x = 0-0.15), prepared via sol-gel method, in order to analyse the effect of substitution-driven structural transition on dielectric and ferroelectric properties ...
Formation of stable radicals in catechin/nitrous acid systems: Participation of dinitrosocatechin
(Elsevier Sci Ltd, Oxford, 2016)
Catechins are transformed into dinitrosocatechins (diNOcats) and then oxidized to the quinones by salivary nitrite under conditions simulating the stomach. This manuscript deals with formation of stable radicals in the NO ...
Ultraviolet-B component of sunlight stimulates photosynthesis and flavonoid accumulation in variegated Plectranthus coleoides leaves depending on background light
(Wiley, Hoboken, 2015)
We used variegated Plectranthus coleoides as a model plant with the aim of clarifying whether the effects of realistic ultraviolet-B (UV-B) doses on phenolic metabolism in leaves are mediated by photosynthesis. Plants were ...
Transformation of Cs-exchanged clinoptilolite to CsAlSi5O12 by hot-pressing
(Elsevier Sci Ltd, Oxford, 2017)
Dense CsAlSi5O12 was successfully obtained by hot pressing of Cs-exchanged clinoptilolite at 900 degrees C. Simultaneous application of high temperature and mechanical pressure allowed formation of CsAlSi5O12 at temperature ...
Antiradical activity of delphinidin, pelargonidin and malvin towards hydroxyl and nitric oxide radicals: The energy requirements calculations as a prediction of the possible antiradical mechanisms
(Elsevier Sci Ltd, Oxford, 2017)
Naturally occurring flavonoids, delphinidin, pelargonidin and malvin, were investigated experimentally and theoretically for their ability to scavenge hydroxyl and nitric oxide radicals. Electron spin resonance (ESR) ...
Parenchyma cell wall structure in twining stem of Dioscorea balcanica
(Springer, Dordrecht, 2017)
Anatomical adaptation of liana plants includes structural changes in cell walls of different tissues: fibers, vessel elements and tracheids. However, the contribution of parenchyma cells to stem twining in liana plants is ...
