A neglected natural source for targeting glioblastoma
(Taylor & Francis Ltd, Abingdon, 2021)
The cytotoxicity of the methanol extract of the freshwater sponge Ochridaspongia rotunda (Arndt, 1937) (Malawispongiidae) was evaluated by MTT assay at in vitro conditions against three brain tumour cell lines (Neuro-2A, ...
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 ...
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 ...
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 ...
First principle study on structural and optoelectronic properties and band-gap modulation in germanium incorporated tin (IV) oxide
(Elsevier, Amsterdam, 2021)
First principle calculations on pure and germanium (Ge) incorporated tin (IV) oxide (SnO2) are performed to understand their structural, electronic, and optical properties at the microscopic level. The optimized ground ...
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 ...
