Cavitation in water under tension is often initiated at nanoscale hydrophobic surface defects that stabilize preexisting nanobubbles. We hypothesize that amphiphilic molecules, such as polar lipids, can adsorb onto these defects and suppress cavitation by removing nanobubble nucleation sites.

Tekočine pod negativnim tlakom oziroma napetostjo so metastabilni sistemi, nagnjeni h kavitaciji—nastanku parnih mehurčkov—ki jih najdemo tako v tehnoloških kot bioloških kontekstih. Primeri segajo od litotripsije in poškodbe tkiva povzročene z ultrazvokom do hidravlike pri rastlinah in izstreljevan ...

The stability of water against cavitation under negative pressures is a phenomenon known for considerable discrepancies between theoretical predictions and experimental observations. Using a combination of molecular dynamics simulations and classical nucleation theory, we explore how nanoscopic hydr ...

Cavitation, the formation of vapor bubbles in metastable liquids, is highly sensitive to nanoscale surface defects. Using molecular dynamics simulations and classical nucleation theory, we show that pure water confined within defect-free walls can withstand extreme negative pressures, far beyond tho ...
