Growth and etching kinetics of tetragonal lysozyme

The morphology and kinetics of the growth and dissolution of lysozyme in aqueous solutions with 2.5% NaCl and at pH=4.5 were studied in-situ with a depth resolution of 300 Å (4 unit cells) by high resolution optical microscopy and digital image processing. The bulk super- or undersaturation, σ, of the solution insidea closed growth cell was controlled by temperature. The growth habit was bound by (110) and (101) faces that grew through layer...
