Electrochemically deposited iridium-oxide: Estimation of intrinsic activity and stability in oxygen evolution in acid solution
(Elsevier Science Sa, Lausanne, 2021)
Hydrated iridiumoxyhydroxide (IrOx) films were electrochemically deposited from an alkaline oxalic solution at constant anodic potentials and by applying a potential cycling protocol, in both cases with variation of the ...
Acoustic communication during reproduction in the basal gobioid Amur sleeper and the putative sound production mechanism
(Wiley, Hoboken, 2021)
Gobioids (Gobiiformes: Gobioidei) are a large group of vocal fishes with four sound types documented during aggressive or reproductive interactions in 23 species. Most attention has been dedicated to sound production in ...
Electrospun Nickel Manganite (NiMn2O4) Nanocrystalline Fibers for Humidity and Temperature Sensing
(MDPI, Basel, 2021)
Nickel manganite nanocrystalline fibers were obtained by electrospinning and subsequent calcination at 400 degrees C. As-spun fibers were characterized by TG/DTA, Scanning Electron Microscopy and FT-IR spectroscopy analysis. ...
Seasonal feeding habits and ontogenetic diet shift of black bullhead (Ameiurus melus) in Lake Sava (Serbia)
(Srpsko biološko društvo, Beograd, i dr., 2021)
The black bullhead is an invasive species that forms dense populations and has a negative impact on the native ichthyofauna. Recent studies indicate that it is one of the most dominant invasive fish species in Serbian ...
Tetragonal CoMn2O4 nanocrystals on electrospun carbon fibers as high-performance battery-type supercapacitor electrode materials
(Royal Soc Chemistry, Cambridge, 2021)
We herein report a simple two-step procedure for fabricating tetragonal CoMn2O4 spinel nanocrystals on carbon fibers. The battery-type behavior of these composite fibers arises from the redox activity of CoMn2O4 in an ...
Surface optical phonon and multi - phonon transitions in YVO4: Eu3+ nanopowders
(Elsevier, Amsterdam, 2021)
In this paper two methods of preparation of yttrium orthovanadate nanopowders were presented: Solid State Reaction (top - down approach) and Solution Combustion Synthesis (bottom - up approach). For starting structural ...
Fast Oxide-Ion Conductors in Bi2O3-V2O5 System: Bi108-xVxO162+x(x=4-9) with 3 x 3 x 3 Superstructure
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2021)
In this study, the possibility to stabilize O-2 ion conductors in Bi2O3-V2O5 system was investigated. Six pseudo-binary Bi2O3-V2O5 mixtures [3.50 lt x(V2O5) lt 8.50 mol%] were thermally treated at 1000 degrees C for 1 ...
Knowledge Use in Education for Environmental Citizenship-Results of Four Case Studies in Europe (France, Hungary, Serbia, Turkey)
(MDPI, Basel, 2021)
The aim of the paper is to contribute to the research on education for environmental citizenship in a comparative perspective. The central concept of education is the complex issue of knowledge. In the present paper, ...
Genotoxicity of fluoride subacute exposure in rats and selenium intervention
(Pergamon-Elsevier Science Ltd, Oxford, 2021)
The aims of this study were to: (i) examine the toxic effects of sodium fluoride (NaF) in blood, liver, spleen, and brain cells of Wistar rats after the subacute exposure; (ii) explore the potential protective properties ...
Repellent activity of Tanacetum parthenium (L.) and Tanacetum vulgare (L.) essential oils against Leptinotarsa decemlineata (Say)
(Cambridge Univ Press, Cambridge, 2021)
The Colorado potato beetle, Leptinotarsa decemlineata (Say), is one of the most destructive pest species to have developed resistance to most chemical insecticides. We determined the composition and evaluated the potential ...
