Hydrophilic and hydrophobic materials are defined by the geometry of water on a flat surface—specifically, the angle between a droplet's edge and the surface underneath it. This is called the ...

Biological cell membranes are made up of phospholipid building blocks that both attract and repel water. Phospholipids are hydrophilic thanks to their polar phosphate group “heads” and hydrophobic ...

hydrophilic and hydrophobic. A hydrophilic substance “loves” water and mixes easily with it. Salt and sugar are examples. A hydrophobic substance “hates” water and generally refuses to mix ...

cells take advantage of the fact that oil and water do not mix and alternate water-loving (hydrophilic) and oil-like, water-fearing (hydrophobic) pearls into the strand. When the strand is submerged ...

A serendipitous observation in a Chemical Engineering lab at Penn Engineering has led to a surprising discovery: a new class of nanostructured materials that can pull water from the air, collect it in ...

Desert beetles and lizards, for example, have evolved to develop surface structures that have both hydrophilic and hydrophobic areas and effectively capture moisture from the air. Water is attracted ...

But micellar water products contain something called micelles - clusters of molecules that are very effective at removing oily substances. To understand why, you need to first know two chemistry terms ...
