Spectrofluorimetric Analysis of Synthetic and isolated lignin from Omorika
(22th International Symposium on Biophysic, 2004)
Lignin is the one of the main constituitive polymers of the plant cell wall that protect plant cell from different kond of stress. Lignin precursors, the plenolic alcohols, belong to the group of phenylpropanoid compounds. ...
Excitation of guided waves in materials with negative refraction
(Elsevier, 2008)
We study, both analytically and numerically, electromagnetic beam transmission through a layered structure that includes a waveguide slab of metamaterial with negative refraction. The resonant excitation of the leaky guided ...

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] ...
Evolution of the microstructure of disperse ZnO powders obtained by the freeze-drying method
(Elsevier Science Sa, Lausanne, 2004)
Freeze-drying, as a cryochemical powder processing method is applied in the synthesis of ZnO submicrometer to narrosized powders. The process involves rapid freezing of the sprayed precursor solution, drying under vacuum ...
