摘要
A readily synthesized dipeptide shows unprecedented gelation behavior when dispersed and submitted to ultrasound in nonsolvents. SEM and FFEM revealed spectacular shape changes from a sheet-like material into a highly interconnected fiber network and ribbons while the dipeptide maintains an anti conformation inside beta-sheets at the molecular scale.
