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 ...
Use of histopathology and elemental accumulation in different organs of two benthophagous fish species as indicators of river pollution
(Wiley, Hoboken, 2015)
The bottom feeding fish species have a good potential to be used for assessments of pollution, as they are under pressure from pollutants from both water and sediments. In this study, the level of similarity of histopathological ...
The assessment of soil availability and wheat grain status of zinc and iron in Serbia: Implications for human nutrition
(Elsevier, Amsterdam, 2016)
The deficiency of zinc (Zn) and iron (Fe) is a global issue causing not only considerable yield losses of food crops but also serious health problems. We have analysed Zn and Fe concentrations in the grains of two bread ...
Antiferromagnetism and heat capacity of NaCo2-xCuxO4 ceramics
(Elsevier Sci Ltd, Oxford, 2017)
Polycrystalline samples of NaCo2-xCuxO4 (x=0, 0.01, 0.03 and 0.05) were synthesized in two different ways: 1) by a mechanochemically assisted solid-state reaction method (MASSR) and 2) by a citric acid complex method (CAC). ...
Comparative study of structural and electrical properties of Pr and Ce doped BiFeO3 ceramics synthesized by auto-combustion method
(Elsevier Science Sa, Lausanne, 2016)
Polycrystalline Bi1-xPr(Ce)(x)FeO3 ceramics (x = 0, 0.03, 0.05 and 0.10) were prepared by auto-combustion method using urea as a fuel. The influence of Pr(Ce) doping on structural, vibrational, morphological, dielectric ...
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 ...
Bacterial cellulose-lignin composite hydrogel as a promising agent in chronic wound healing
(Elsevier, Amsterdam, 2018)
Lignins and lignin-derived compounds are known to have antibacterial properties. The wound healing agents in the form of dressings produce faster skin repair and decrease pain in patients. In order to create an efficient ...
Mechanical and microstructural properties of alkali-activated fly ash geopolymers
(Elsevier, Amsterdam, 2010)
This paper investigates the properties of geopolymer obtained by alkali-activation of fly ash (FA), i.e. the influence of characteristics of the representative group of FA (class F) from Serbia, as well as that of the ...
Effects of the concentrated NH4NO3 solution on mechanical properties and structure of the fly ash based geopolymers
(Elsevier Sci Ltd, Oxford, 2013)
The geopolymers based on fly ash were exposed to the concentrated (6 M) NH4NO3 solution for 540 days. The highest compressive strength decrease occurred in the initial 28 days testing period. Study of the effects of the ...
