Scientific Video Award

Rebound of a oil-lubricated water drop on a hydrophilic surface

Muhammad Saeed Saleem

Capture Speed : 20,000fps

Outline

A compound drop consisting of a water core and a silicone oil shell impacts on a hydrophilic glass substrate. Remarkably, the oil shell acts as a lubricating layer upon impact, promoting either full or partial rebound of the inner water drop from the glass substrate, even when this glass substrate is completely hydrophilic. Additionally, a cavity is formed in the center of the spreading water core. When the water core retracts, this cavity collapses and a sharp vertical oil jet is ejected at high speed.

Thunder and lightning

Harald Kleine

Capture Speed : 10,000,000fps and 1,250,000fps

Outline

Thunder and Lightning- A sequence of high-speed schlieren visualizations of the spark and its associated shock wave, generated with a Ruhmkorff coil. Recording speeds are 10 million fps for the first clip and 1.25 million fps for the remaining ones.

Bubbles in earth conditions VS Bubbles in microgravity conditions

Patricia Vega Martinez

Capture Speed : 2,000fps

Outline

The diffusion-driven growth of a foam ball in supersaturated liquids. Under normal gravity conditions, a bubble cloud grows by diffusion, however this process is interrupted after a few milliseconds when the bubble cloud starts a buoyancy-included rising motion. On the other hand, under micro-gravity conditions bubbles grow by pure diffusion.
