The effects of plant growth regulators on growth, yield, and phenolic profile of lentil plants
(Academic Press Inc Elsevier Science, San Diego, 2012)
The effects of plant growth regulators (PGRs) such as gibberellic acid (GA(3)), indole-3-acetic acid (IAA), kinetin, Prohexadione-Calcium (Prohex-Ca), and Topflor on lentil plants were investigated employing physiological ...
Structure and properties of Ni-Zn ferrite obtained by auto-combustion method
(Elsevier Science Bv, Amsterdam, 2015)
Nanosized nickel zinc ferrite powders with general formula Ni1-xZnxFe2O4 (x=0.0, 0.3, 0.5, 0.7, 1.0) were synthesized by an auto-combustion method starting from metal nitrates. X-ray analysis indicated the formation of ...
Chemical stability and electrical properties of Nb doped BaCe0.9Y0.1O3-delta as a high temperature proton conducting electrolyte for IT-SOFC
(Elsevier Sci Ltd, Oxford, 2013)
BaCe0.9-xNbxY0.1O3-delta (where x=0, 0.01, 0.03 and 0.05) powders were synthesized by solid-state reaction to investigate the influence of Nb concentration on chemical stability and electrical properties of the sintered ...
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 ...
Electrical properties of niobium doped barium bismuth-titanate ceramics
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
BaBi4Ti4-5/4xNbxO15 (BBNTx, x = 0.0.05, 0.15, 0.30) ceramics have been prepared by solid state method. XRD data indicate the formation of single-phase-layered perovskites for all compositions. SEM micrographs suggest that ...
Influence of electrodeposition parameters of Ni-W on Ni cathode for alkaline water electrolyser
(Pergamon-Elsevier Science Ltd, Oxford, 2013)
In this study, different Ni-W coatings, obtained by cheap and technologically simple electrodeposition method, were examined as potential electrocatalysts for the hydrogen evolution reaction (HER). All electrodepositions ...
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 ...
Fast photoluminescence quenching in thin films of 4,4 '-bis(2,2-diphenylvinyl)-1,1 '-biphenyl exposed to air
(Elsevier, Amsterdam, 2015)
The photoluminescence (PL) quenching mechanism of UV light and air-exposed amorphous thin films of 4,4'-bis(2,2-diphenylvinyl)-1,1'-biphenyl (DPVBi), a well-known hole-transport material used in organic light-emitting ...
Genetic diversity and virulence of Xanthomonas campestris pv. campestris isolates from Brassica napus and six Brassica oleracea crops in Serbia
(Wiley, Hoboken, 2019)
The present study provides insight into the diversity of 147 Xanthomonas campestris pv. campestris (Xcc) isolates obtained from six Brassica oleracea vegetable crops (broccoli, cabbage, cauliflower, collard greens, kale, ...
Demographic flexibility influences colonization success: profiling invasive fish species in the Danube River by the use of population models
(Springer, Dordrecht, 2015)
Invasive species have the ability to modify their life-history traits in newly colonized areas, with positive shifts in specific life history traits under favourable environmental conditions. If such positive changes in ...
