Webhomogeneous iodine complexation (whether via iodine vapor deposition or iodine sol-utions) for water-insoluble polymers having various compositions and geometries. Our present study reports the fabrication of iodine complexes of two medically rele-vant polymer families, specifically polyamides (PA) and polyurethanes (PU). The bioci- Web7 sep. 2024 · Complexation of aroma compounds using starch inclusion complex could be a potential approach due to the hydrophobicity of the left-handed single helical structure. In the present study, we used starch of three different V-type structures, namely V 6h, V 7, and V 8, to encapsulate six different aroma compounds, including 1-decanol (DN), cis -3 ...

Iodine, for example, is slightly soluble in water to give a yellowish-brown solution. Brown solutions are also formed with alcohol, ether, ketones, and other compounds acting as Lewis bases through an oxygen atom, as in the following example: force bellow star wars
