摘要：

Amphiphilic molecules and water are the basic components of many different systems; their morphology and topology conditions depend on many physical and chemical parameters, mainly concentration. These systems may be either three dimensional (vesicles, micelles) or two dimensional (membranes). In this paper, we investigate Langmuir monolayers on water by means of X-ray reflectivity, with the aim to characterize the liquid expanded/liquid condensed and liquid condensed/solid transitions. We also study the structure of the Newton black film (i.e., the ultimate stage of the thinning of a soap film). The main result for the latter problem is the complete lack of water and the two-dimensional crystallization of this "inverted membrane".
