An EPFL Bachelor's student has solved a mystery that has puzzled scientists for 100 years. He discovered why gas bubbles in narrow vertical tubes seem to remain stuck instead of rising upward. According to his research and ...

Tiny gas-filled bubbles in the porous rock found around hot springs are thought to have played an important role in the origin of life. Temperature differences at the interface between liquid phases could therefore have initiated ...

The formation of air bubbles in a liquid appears very similar to its inverse process, the formation of liquid droplets from, say, a dripping water faucet. But the physics involved is actually quite different, and while those ...

Hydraulic fracturing, or fracking, provides critical energy for society, but also uses large amounts of fresh water while producing corresponding amounts of wastewater. Water-based foams, which use about 90 percent less water ...

The chemical composition of gases emitted from volcanoes—which are used to monitor changes in volcanic activity—can change depending on the size of gas bubbles rising to the surface, and relate to the way in which they ...

An international team of researchers has found a way to make solar hydrogen generation more efficient in microgravity environments. In their paper published in the journal Nature Communications, the group describes what they ...
When gold nano particles in water are illuminated by a laser, they get very hot: well above the boiling point of water. The formation of vapour bubbles caused by this, is well-known. New experiments, however, using a very ...
