When foams collapse (and when they don t)

A second crack event in the film (b) causes a collapse front to be formed which sweeps up the RVPB. view more Credit: Tokyo Metropolitan University Tokyo, Japan - Researchers from Tokyo Metropolitan University have revealed how liquid foams collapse by observing individual collapse events with high-speed video microscopy. They found that cracks in films led to a receding liquid front which sweeps up the original film border, inverts its shape, and releases a droplet which hits and breaks other films. Their observations and physical model provide key insights into how to make foams more or less resistant to collapse.

Shuffling bubbles reveal how liquid foams evolve

Note how bubbles move in the same direction along the same row, or in exactly the opposite direction in adjacent rows over long. view more Credit: Tokyo Metropolitan University Tokyo, Japan - Researchers from Tokyo Metropolitan University studied the dynamics of foams. When a drop of water was added to a foam raft, the bubbles rearranged themselves to reach a new stable state. The team found that bubble movement was qualitatively different depending on the range of bubble sizes present. Along with analogies with soft-jammed materials, these findings may inspire the design of new foam materials for industry.
