Improvement of barium titanate properties induced by attrition milling
(Elsevier Sci Ltd, Oxford, 2012)
Barium titanate powder was prepared by soft chemical process from polymeric precursors (modified Pechini process). The synthesized barium titanate (BT) powder was nanosized and the factor of agglomeration (F-agg) pointed ...
Influence of mechanical activation on sphene based ceramic material synthesis
(Elsevier Sci Ltd, Oxford, 2013)
Sphene (CaTiSiO5), a calcium titanosilicate ceramic has been prepared from a powder mixture of CaCO3, TiO2 and SiO2 using vibromilling for homogenization and activation of precursors. The mechanochemical process initially ...
High-voltage electrophoretic deposition of preferentially oriented films from multiferroic YMn2O5 nanopowders
(Elsevier Sci Ltd, Oxford, 2013)
Processing of the YMn2O5 powder is very challenging, since it decomposes to YMnO3 and Mn3O4 at temperatures close to 1180 degrees C, while samples consolidation commonly demands high temperatures. The main goal of this ...
Redox therapy in neonatal sepsis: reasons, targets, strategy, and agents
(Lippincott Williams & Wilkins, Philadelphia, 2014)
Neonatal sepsis is one of the most fulminating conditions in neonatal intensive care units. Antipathogen and supportive care are administered routinely, but do not deliver satisfactory results. In addition, the efforts to ...
Preparation and characterization of Cu and Zn modified nickel manganite NTC powders and thick film thermistors
(Elsevier, Amsterdam, 2013)
A simple ball milling/thermal treatment procedure was applied to obtain fine thermistor powders. Three different powder compositions were analyzed-Cu0.2Ni0.5Zn1.0Mn1.3O4, Cu0.25Ni0.5Zn1.0Mn1.25O4 and Cu0.4Ni0.5Mn2.1O4. XRD ...
X-ray absorption near-edge structure micro-spectroscopy study of vanadium speciation in Phycomyces blakesleeanus mycelium
(Springer Heidelberg, Heidelberg, 2015)
Vanadium speciation in the fungus Phycomyces blakesleeanus was examined by X-ray absorption near-edge structure (XANES) spectroscopy, enabling assessment of oxidation states and related molecular symmetries of this transition ...
Indicators of unsustainable fishery in the Middle Danube
(Wiley, Hoboken, 2016)
Fishery in the Danube River basin has been characterised over the past century by increasing fishing levels, illegal fishing practices and poor regulations. However, there is a remarkable lack of available information on ...
ZnS:Mn nanoparticles functionalized by PAMAM-OH dendrimer based fluorescence ratiometric probe for cadmium
(Elsevier, Amsterdam, 2015)
We report a nanocomposite of ZnS:Mn quantum dots and a third generation PAMAM-OH dendrimer (ZnS:Mn"PAMAM-OHG=3) which was rationalized to be used as ratiometric nanosensor for Cd2+ in aqueous solution. The nanoparticles ...
Effects of acute cooling on fish electroretinogram: A comparative study
(Elsevier Science Inc, New York, 2015)
Temperature dependence of electroretinogram (ERG) was investigated in 3 fish species occupying different habitats - dogfish shark (Scyliorhinus canicula), Prussian carp (Carassius gibelio) and European eel (Anguilla ...
