The role of surface tension in biological symmetry

EPFL researchers have discovered that symmetry in the human body is influenced by surface tension, the same mechanical phenomenon that allows lightweight insects to walk on water. A paper discussing this surprising finding, ...

Investigating glowing glass droplets on the ISS

Researchers will soon be studying materials samples on the ISS. The materials in question are super-hard and corrosion-resistant alloys of palladium, nickel, copper and phosphorus—also known as metallic glasses. A high-tech ...

Imaging chemical kinetics at liquid-liquid interfaces

Scientists led by EPFL have developed a new method to measure chemical kinetics by imaging progress of a reaction at a liquid-liquid interface embedded in a laminar-flow liquid microjet. This method is ideal for studies of ...

Extraterrestrial mining would emulate 'tears of wine' phenomenon

Tears of wine is a phenomenon frequently observed as a ring of wine formed near the top of the glass generates droplets that fall back into the wine. This phenomenon can be explained by the Marangoni effect driven by the ...

Improving print quality by using surfactants

Have you ever spilled coffee onto a table? If so, you have probably noticed that the resulting stain is not nicely uniform but has a notable ring around it. This forgettable oddity is daily business in the printing industry, ...

Controlling how 'odd couple' surfaces and liquids interact

The wettability of a surface—whether drops of water or another liquid bead up or spread out when they come into contact with it—is a crucial factor in a wide variety of commercial and industrial applications, such as ...
