Abstract
Like dissolves like: Bisureas containing environmentally benign CO 2-philic groups derived from peracetylated gluconic acid dissolve in supercritical CO2 at 298 K and 62 MPa. Upon depressurization of the CO2, the initially powdery bisureas (left image) form microfibrillar foams (right image). (Figure Presented).
