20.500.12556/RUL-168116 Impact of nanoscopic impurity aggregates on cavitation in water 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 hydrocarbon droplets influence cavitation in water. Our findings reveal that while a macroscopic volume of absolutely pure water withstands around −120 MPa of tension, introducing a single nanoscopic oil droplet, merely a few nanometers in radius, brings this cavitation threshold to around −30 MPa, closely matching the values typically observed in highly controlled experiments. The unavoidable presence of nanoscopic hydrophobic impurities, even in highly purified water used in experiments, imposes a practical limit on achieving the theoretical tensile strength in realistic settings. More broadly, our study highlights the profound impact of nonpolar residues on nucleation phenomena and enhances our understanding of metastability in real-world systems. cavitation bubble droplet water oil molecular dynamics simulation voda kapljevina molekularna dinamika true false true Angleški jezik Slovenski jezik Članek v reviji 2025-03-28 14:37:28 2025-03-28 14:37:30 2025-04-07 10:48:06 0000-00-00 00:00:00 2025 0 0 9 str. art. 106243 Vol. 62 2025 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 532 2468-0230 10.1016/j.surfin.2025.106243 230475267 1-s2.0-S2468023025005024-main.pdf 1-s2.0-S2468023025005024-main.pdf 1 E9B72510278F4BE169353E8E791EF276 8169f6aba5aaec1543cf32dd8041f47190ac153a5f4934084e6778e376be40c1 0da0ac39-0bd9-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201147 https://www.sciencedirect.com/science/article/pii/S2468023025005024 0 c3258c05-0bd8-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=201145 Fakulteta za matematiko in fiziko 0 0 0
