The long-term stability of nanobubbles with high internal gas pressure is a puzzling question for nanobubble researchers. classical Molecular Dynamics simulation based on LAMMPS software was used to evaluate the performance an oxygen density. This research consists two main cases. In first case, bubble behavior examined 3247 O2 molecules embedded in 4.5 nm radius spherical volume represent and ...

Nanobubbles are nanoscopic gaseous domains than can exist on solid surfaces or in bulk liquids. They have attracted significant attention the last decade due to their long-time (meta)stability and ready potential for real-world applications, especially environmental engineering more sustainable ecosystems, water treatment, irrigation, crop growth. After reviewing important nano-bubble science a...

Abstract The electrical stability and reliability of two-dimensional (2D) crystal-based devices are mainly determined by charge traps in the device defects. Although nanobubble structures as defect sources 2D materials strongly affect performance, local charge-trapping behaviors nanobubbles poorly understood. Here, we report a Fermi-level hysteresis imaging strategy using Kelvin probe force mic...

The fabrication and initial applications of nanobubbles (NBs) have shown promising results in recent years. A small particle size is a basic requirement for ultrasound contrast-enhanced agents that penetrate tumor blood vessel pores to allow for targeted imaging and therapy. However, the nanoscale size of the particles used has the disadvantage of weakening the imaging ability of clinical diagn...

Plasmonics is emerging from among the most promising means for generating and controlling thermal energy at the nanoscale. In this approach, metallic nanoparticles are laser heated at plasmon resonant wavelengths that depend on the size, shape and properties of the particles. Key attributes of this method include remote optical activation, nanoscale resolution and efficient photothermal transdu...
