Fountain Created by Lasers, Marangoni Effect is the Cause

Physicists have achieved a record-setting level of electron mobility in a thin film of ternary tetradymite. Materials like this will be essential for more efficient and sustainable electronic devices that can do more work with less power.

Researchers achieved record-breaking electron mobility with a new material, paving the way for revolutionary advances in electronic devices and technology.

Skoltech researchers and their colleagues from MIPT and China's Center for High Pressure Science and Technology Advanced Research have computationally explored the stability of the bizarre compounds of hydrogen, lanthanum, and magnesium that exist at very high pressures. In addition to matching the various three-element combinations to the conditions at which they are stable, the team discovered five completely new…

Recently, researchers from the Changchun Institute of Optics, Fine Mechanics and Physics of the Chinese Academy of Sciences published a study in Materials Today Physics that sheds light on the light emitting properties of perovskite materials after being subjected to femtosecond laser processing.

Engineers have discovered that they can actually move deep water and create upward fountains by shining laser beams on the water's surface. The finding, credited to the Marangoni effect, has potential to impact fluid dynamics in many applications.

A pair of University of Houston engineers has discovered that they can create upward fountains in water by shining laser beams on the water's surface. Jiming Bao, professor of electrical and computer engineering at UH, and his postdoctoral student Feng Lin, attribute the finding to a phenomenon known as the Marangoni effect, which causes convection and explains the behavior of water when differences in surface…
