Microstructural characterization of mechanically activated ZnO-Cr2O3 system
(Elsevier Sci Ltd, Oxford, 2005)
An equimolar mixtures of starting ZnO and Cr2O3 powders were mechanically activated by grinding using a planetary ball mill for various periods of time (40-320min). Formation of nanocrystalline ZnCr2O4 as normal spine] ...
Enhanced photocatalytic activity of Ag modified ZnO nanopowders prepared by solvothermal method / POBOLJŠANA FOTOKATALITIČKA AKTIVNOST SREBROM MODIFIKOVANIH ZnO NANOPRAHOVA DOBIJENIH SOLVOTERMALNIM POSTUPKOM
(Српско кристалографско друштво, Београд, Serbian Crystallographic Society, Belgrade, Serbia, 2015)
Zinc oxide is a well-known photocatalyst mainly used to degrade organic water
pollutants using artificial or sunlight. It is one of the most widely used material because of its
good photoactivity, biological and chemical ...
Analysis of isothermal sintering of zinc-titanate doped with MgO
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2007)
The aim of this work was analysis of isothermal sintering of zinc titanate ceramics doped with MgO obtained by mechanical activation. Mixtures of ZnO, TiO2 and MgO (0, 1.25 and 2.5%) were mechanically activated 15 minutes ...
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 ...
Electroretinographic evaluation of spectral sensitivity in yellow and silver eels (Anguilla anguilla)
(Cambridge Univ Press, New York, 1998)
Although differences in visual pigments between developmental stages of the European eel are well known, the expected differences in spectral sensitivity have not been demonstrated at the electrophysiological level. In ...
Temporal analysis of electroretinographic responses in fishes with rod-dominated and mixed rod-cone retina
(General Physiol And Biophysics, Bratislava, 2009)
Photoreceptor content of fish retinas could be accessed by comparative electroretinographic (ERG) studies using flickering light stimuli that could separate rod-mediated vision where critical flicker frequency (CFE, frequency ...
Relevance of the ability of fructose 1,6-bis(phosphate) to sequester ferrous but not ferric ions
(Elsevier Sci Ltd, Oxford, 2011)
The cytoprotective activity of F16BP has been documented in severe conditions such as convulsions, reperfusion injury, septic shock, diabetic complications, hypothermia-induced injury, UV-provoked skin damage and in other ...
Fluctuating vs. Continuous Exposure to H2O2: The Effects on Mitochondrial Membrane Potential, Intracellular Calcium, and NF-kappa B in Astroglia
(Public Library Science, San Francisco, 2013)
The effects of H2O2 are widely studied in cell cultures and other in vitro systems. However, such investigations are performed with the assumption that H2O2 concentration is constant, which may not properly reflect in vivo ...
The effects of wild-type and mutant sod1 on smooth muscle contraction
(Srpsko biološko društvo, Beograd, i dr., 2015)
In this work we compared the mutated liver copper zinc-containing superoxide dismutase (SOD1) protein G93A of the transgenic rat model of familial amyotrophic lateral sclerosis (FALS), to wild-type (WT) rat SOD1. We examined ...
The role of autophagy and lipolysis in survival of astrocytes under nutrient deprivation
(Elsevier Ireland Ltd, Clare, 2015)
Astrocytes can survive nutrient deprivation (ND) for days. However, the pro-survival strategy of astrocytes under such a metabolic challenge is still not clear. In the present study, we examined the effects of inhibition ...
