Influence of rare earth treatment on interfacial ...

Jan 25, 2007  Rare earth treatment, relatively, seems to have caused the increase of quinoid carbonyl functions (peak I of O 1s spectra). In addition, rare earth treatment promoted the reduction of peak II in the O 1s spectra (carbonyl oxygen atoms in esters, amides, anhydrides and oxygen atoms in hydroxyls or ethers). Also, there is a decrease in the ester ...
