Intracellular reorganization and ionic signaling of the phycomyces stage i sporangiophore in response to gravity and touch
(Communicative and Integrative Biology, 2013)
Unicellular zygomycete fungus Phycomyces blakesleeanus exhibits a typical apical growth that depends on a complex interaction of different physiological processes. Sensitivity to the light, wind, barriers, touch and gravity ...
Converting low dose radiation to redox signaling
(Plant Signaling and Behavior, 2013)
In contrast to the damaging effects of high doses, low dose radiation (UV, gamma) has been reported to provoke constructive changes in plants. However, the mechanisms by which plants recognize and respond to low dose ...
Antioxidative status and acclimatization capacity of bamboo - potential use for air quality improvement in urban areas
(Fresenius Environmental Bulletin, 2013)
Phyllostachis bissetti was introduced to urban areas in Belgrade with the aim to improve the quality of air polluted by heavy traffic. Dust released from fuel combustion adsorbed on the leaves reaching up to 10% of leaf ...
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 ...
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 ...
Synthesis and Characterization of Pt Catalysts on SnO2 Based Supports for Oxygen Reduction Reaction
(Electrochemical Soc Inc, Pennington, 2013)
The oxygen reduction reaction was studied at Pt nanocatalysts on two different tin oxide based supports, Sb-SnO2 and Ru-SnO2, in acid solution. Tin oxide based supports were synthesized by hydrazine reduction method. ...
Antifungal activity of quinhydrone against saccharomyces cerevisiae
(Fresenius Environmental Bulletin, 2013)
Quinhydrone (QH) is a redox active charge transfer complex commonly used as a redox standard. Information on quinhydrone generation in plants is scarce and its physiological role is still unclear. Recently we have showed ...
