(17) The ESCA depth profiling experiments involved several elemental analyses (Na, Ba, O, B, Si, Al, and C) for both the product-contact surface and various depths (0.01-0.30 micron) beneath the surface.
(18) The addition of the silicone-containing polyol did not significantly lower the surface wettability, although ESCA-measured silicon content increased and physical properties were unfavourably affected by the incorporation of this co-soft segment.
(19) Future research in this area will include the use of surface analytical techniques such as Auger electron spectroscopy and ESCA.

Illicium
Definition:
(n.) A genus of Asiatic and American magnoliaceous trees, having star-shaped fruit; star anise. The fruit of Illicium anisatum is used as a spice in India, and its oil is largely used in Europe for flavoring cordials, being almost identical with true oil of anise.
Example Sentences:
