The method is shown to be capable of detecting nitrogen incorporation by variations in NH stretching band intensity and oxygen incorporation by carbonyl related bands. The method is particularly sensitive to loss of aromaticity as seen by evolution of the aromatic and aliphatic CH stretching band intensities.

Effects of cold plasma treatment on seed germination and seedling growth of soybean

“…4), which was in consistent with Bormashenko et al who found that cold radiofrequency air plasma treatment dramatically decreased the apparent contact angle of lentil and wheat seeds23. The plasma treatment could change the chemical structure and the roughness of the surface, and finally lead to a dramatic change of wetting behavior of the seed, which may account for the increase in water uptake of seed25.…”

Improvement of wheat seed vitality by dielectric barrier discharge plasma treatment

“…In this study, the wheat seed coat was softened after the DBD plasma treatment; these phenomena suggest that the wheat seed surface underwent oxidation by the DBD plasma, which might account for the increase in water uptake of the wheat seeds. Wild and Kesmodel [] reported that the chemical structure and roughness of the seed surface could be changed by a plasma treatment, which resulted in the change of wetting behavior of the seed and affected its water uptake. Because the hydrophily of the seeds was enhanced by the plasma treatment, its ability to absorb water would also be enhanced, leading to better growth [Jiang et al, ].…”

Physical mechanisms of interaction of cold plasma with polymer surfaces

“…The plasma treatment creates a complex mixture of surface functionalities which influence physical and chemical properties of polymers, and results in a dramatic change in the wetting behaviour of the surface; this is true for both solid and liquid surfaces [7][8][9][10][11][12][13][14][15][16][17].…”
