The generation of liquid foams is at the heart of numerous natural, technical or scientific processes. Even though the subject of foam generation has a long-standing history, many recent progresses have been made in an attempt to elucidate the fundamental processes at play.

Foam-in-Foam Polyurethane Composite
Journal of Cellular Plastics, 2002Open-pore flexible polyurethane (PUR)foams with various pore sizes (1–8 mm)were used as 3-D filler to reinforce low-density, closed-cell PUR flexible foam. The final composite has a “foam-in-foam” structure. Compared to the unfilled PUR flexible foam, the composite exhibits considerable improvement on mechanical properties: with the same density, the ...

Langmuir, 2010
Because of their layered structure, thermotropic smectic mesogens can form stable foams. In this study, two-dimensional foams of 8CB are prepared in the smectic A phase. We determine the structures of the foam cells and study the aging dynamics. Three stages of foam evolution are distinguished. The freshly prepared foam consists of multilayers of small

Materials Characterization, 1972
Abstract The shape, distribution, arrangement, and stability of cells in a typical foam and polycrystal are compared, and their observed dissimilarity is attributed to a fundamental difference in the structure of the two systems. In particular, it is shown that certain features of a polycrystal may be accounted for, if the surface of its grains is ...

Endeavour, 1985
Abstract This article reviews the general properties of liquid and solid foams; the principles underlying their preparation and stability; and the ways in which they can be broken down. It then goes on to consider how foams can be used in pharmacy; for example, to extend the period of absorption of drugs. It also discusses the use of foam flotation —
