Comparison of polyamine, phenol and flavonoid contents in plants grown under conventional and organic methods
(International Journal of Food Science and Technology, 2008-10-01) [Artigo]
The objective of this work was to compare the contents of polyamines (putrescine, spermidine and spermine), and total soluble phenols and flavonoids in parts of plants grown under either organic or conventional cropping, ...
Schottky emission in nanoscopically crystallized Ce-doped SnO2 thin films deposited by sol-gel-dip-coating
(Thin Solid Films, 2008-11-28) [Artigo]
This paper reports the electrical effects of the incorporation of Ce(III) or Ce(IV) in SnO2 thin films, prepared by the sol-gel-dip-coating technique. This doping has drastically increased the resistivity compared to undoped ...
