Overview

Molecular dynamics simulations reveal interfacial forces maintaining nanobubble stability and energy distribution patterns.

Key Points

  • This study aims to understand the stability of nanobubbles and the role of molecular forces at the nanoscale.
  • Utilized molecular dynamics simulations to analyze oxygen nanobubbles of sizes 3, 5, and 8 nm in water.
  • Evaluated structural evolution, surface tension, electrostatic forces, and hydrogen-bond networks at the gas-liquid interface.
  • Examined the relationship between hydrogen-bond density and interfacial mobility.
  • The 3 nm bubble showed the largest motion radius at 3.5 nm, significantly larger than 5 and 8 nm bubbles.
  • Surface tension underpredicted by 35.7% for the 3 nm bubble, indicating other stabilizing forces are at play.
  • The peak hydrogen-bond count for Charge4 was 11.6 times that of Charge2, showing a clear relationship with restricted interfacial water mobility.
