Resumen:

The phase diagram of the dioctadecylamine Langmuir monolayer is determined from pressure-area isotherms and from direct observations of the monolayer using Brewster angle microscopy. In the L - S1 transition, the domains of the emerging phase are outstanding six-fold dendrites. We study the factors that modify the form of growth of these domains, and we are able to detect that in certain specific conditions of undercooling, the domains have a fingering instability and after some growing time present tipsplitting. If undercooling persists, the domains undergo a transition to side-branching. © 2005 by Imperial College Press. All rights reserved.
