Nitrate does not result in iron inactivation in the apoplast of sunflower leaves
(Amer Soc Plant Biologists, Rockville, 2003)
It has been hypothesized that nitrate (NO3-) nutrition might induce iron (Fe) deficiency chlorosis by inactivation of Fe in the leaf apoplast (H.U. Kosegarten, B. Hoffmann, K. Mengel [1999] Plant Physiol 121: 1069-1079). ...
The effects of the pause to pulse ratio in the regime of pulsating overpotential on the formation of honeycomb-like structures
(Elsevier Science Inc, New York, 2009)
The formation of honeycomb-like structures in the pulsating overpotential (PO) regime was examined by scanning electron microscopy (SEM). The honeycomb-like structures obtained with a square-wave PO of different pause to ...
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] ...
The nature of structural changes in nanocrystalline ZnO powders under linear heating conditions
(Elsevier Sci Ltd, Oxford, 2004)
The nature of exothermal and irreversible structural changes observed during linear heating of nanocrystalline ZnO powders was investigated using differential scanning calorimetry, X ray, SEM and TEM analysis. Nanocrystalline ...
