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 ...
Characterization of Al-W oxide coatings on aluminum formed by pulsed direct current plasma electrolytic oxidation at ultra-low duty cycles
(Elsevier Science Sa, Lausanne, 2021)
The growth of thin oxide coatings on the aluminum substrate in water-based sodium tungstate electrolyte by plasma electrolytic oxidation (PEO) is discussed and experimentally illustrated. The growth is carried out using a ...
Seasonal variations of macro-, micro-, and toxic elements in tissues of vimba bream (Vimba vimba) from the Danube River near Belgrade, Serbia
(Springer Heidelberg, Heidelberg, 2021)
Vimba bream (Vimba vimba) individuals were collected from the Danube River near Belgrade, from May 2016 to May 2017. Samples of muscle and liver tissue were analyzed for concentrations of 25 elements (macro-, micro-, and ...
Flexible lead-free NBT-BT/PVDF composite films by hot pressing for low-energy harvesting and storage
(Elsevier Science Sa, Lausanne, 2021)
The idea of this work is finding the way to efficiently and safely use mechanical energy released in small quantities around us to power up small-scale electronic devices used in everyday life. To this purpose, flexible ...
Chitosan and pectin-based films and coatings with active components for application in antimicrobial food packaging
(Elsevier Science Sa, Lausanne, 2021)
This investigation was aimed to develop films and coatings based on natural biopolymers and active components, with physicochemical and functional properties for application in antimicrobial packaging. Biopolymer films ...
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 ...
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 ...
A comparison of major taste- and health-related compounds among newly released Italian strawberry cultivars
(Int Soc Horticultural Science, Leuven 1, 2021)
Strawberry (Fragaria x ananassa Duch.) is one of the most popular edible fruit worldwide of which consumption constantly increases with the development of new cultivars available at almost all season. Besides being delicious, ...
Immobilization of yeast cell walls with surface displayed laccase from Streptomyces cyaneus within dopamine-alginate beads for dye decolorization
(Elsevier, Amsterdam, 2021)
High amounts of toxic textile dyes are released into the environment due to coloring and wastewaters treatment processes' inefficiency. To remove dyes from the environment and wastewaters, researchers focused on applying ...
Raspberry seeds extract selectively inhibits the growth of human lung cancer cells in vitro
(Taylor & Francis Ltd, Abingdon, 2021)
This study was focused on in vitro cytotoxicity screening of the raspberry seeds methanol extract towards a number of cancer cell lines of human origin. The tested extract at the preferred concentrations (IC50 lt 30 mu ...
