摘要：

The heterogeneous nucleation of hen-egg-white lysozyme (HEWL) crystals has been investigated using a double(thermal)-pulse technique, thus detaching nucleation from the growth stage. n(t) dependencies of the nucleus number, n, vs. time, t, were plotted for surfaces rendered hydrophobic (by means of hexamethyl-disilazane) and for bare glass surfaces. Preferred crystallite orientation supplied additional information. The discussion is based on the classical Stranski-Kaischew theory of crystal nucleation. With a purposely developed new technique the adhesion energies have been measured for HEWL crystals, grown on different supports. (C) 1999 Elsevier Science B.V. All rights reserved.
