Recently, Dowling et al synthesized a hydrophobically modified chitosan (hm-chitosan) by attaching benzene-n-octadecyl tails to the backbone of chitosan via reaction with 4-octadecylbenzaldehyde.
The carbon and nitrogen content yielded from ortho hydroxytoluene chitosan and those yielded from initial chitosan were detected by Elemental Analyser (Vario EL/micro cube, Elementar Inc., Germany), further the degree of deacetylation (DD) of chitosan and the DS of modified chitosan were calculated according to Eq.1 and Eq.2 respectively [11]: (1) (2) Where, WC, WN represents the percentage of carbon and nitrogen content in the material respectively.

This is consistent with Ma et al [19] about the impact of sodium tripolyphosphate on the rheological characteristics of paste cement.

X-ray photoemission spectroscopy (XPS) analyses were performed with a Kratos Axis Ultra DLD using a high-resolution monochromatic Al-Kα line X-ray source at 1486.6 eV and a photoelectron take-off angle normal to the surface.

This technique allows ameliorating both the high temperature (1000-1300°C) properties by homogeneous dispersion of fine oxides particles in the alloy and the medium temperature ones (800-1000°C) by precipitation of an intermetallic γ phase of Ni3(Al, Ti) type.
