The starting materials, 4-aminoazobenzene, 2-aminoazotoluene, stearic acid, palmitic acid, tetradecanoic acid, and dodecanoic acid
, were purchased from Alfa Aesar Tianjin Chemicals, Aldrich Chemicals, and TCI Shanghai Chemicals, respectively.

They revealed that dodecanoic acid
(C12) and decanoic acid (C10) both stimulated CCK secretion, but ghrelin plasma levels only significantly decreased in the C12-acid group.

The resultant metallic coating had a superhydrophilic nature, but could he switched into superhydrophohic by spraying an acetone solution of dodecanoic acid
while the sprayed surface remained within a temperature range of 100-200[degrees]C, although dodecanoic acid
itself has a hydrophilic nature.
