Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon chains, which makes it hydrophobic and insoluble in water. Mixtures of the two are called emulsions, and emulsifiers exist that can stabilize them into a thicker temporary or permanent mixture. Cooks use such a technique to make vinaigrette, a salad dressing consisting primarily of oil and vinegar with emulsifiers such as mustard, honey or mayonnaise. https://phys.org/news/2026-06-nanoscale-droplets-dont-coalesce-microscale.html Bio & Medicine Mon, 29 Jun 2026 09:00:04 EDT news701942376 A research team has developed a methodology to precisely design and control the "degree of disorder" in nanopattern arrays using metal-infiltrated block copolymer (BCP) thin films.

For macroscopic (millimeter-scale) drops, this behavior can be explained using continuum theory. However, when nanoscale (10–9 mm) droplets spread on surfaces, a force called line tension becomes relevant and mysteriously changes sign.
