摘要：
A new mechanism of network recrystallization has been demonstrated in supercritical CO2 in which a "saw tooth" pressure oscillation has been employed to induce growth of a filament microstructure in a crystalline material (aspartame). During the pressure cycles repeated deposition of material occurs onto the filaments which ultimately grow and interconnect to form small, discrete clusters of approximately 100 μm diameter. © 1990 American Chemical Society.
