Nanobubbles (<200 nm in diameter) have several unique properties such as long lifetime in liquid owing to its negatively charged surface, and its high gas solubility into the liquid owing to its high internal pressure. They are used in variety of fields including diagnostic aids and drug delivery, while there are no reports assessing their effects on the growth of lives. Nanobubbles of air or o...

Here we studied the regimes of optical breakdown in water, stimulated by nanosecond and picosecond laser pulses at a wavelength 1064 nm. A distinctive feature our theoretical model, confirmed experiment, is that case develops on heterogeneous centers-clusters gas nanobubbles. To best knowledge, this first study role clusters nanobubbles liquids are transparent to pump radiation. In experiment d...

Liquid jets that develop in surface nanobubble collapse are weaker than similar sized spherical bubble collapse, resulting reduced damage and a constant pit depth, independent of initial size.

Decompression illness (DCI) occurs following a reduction in ambient pressure. Decompression bubbles can expand and develop only from pre-existing gas micronuclei. The different hypotheses hitherto proposed regarding the nucleation and stabilization of gas micronuclei have never been validated. It is known that nanobubbles form spontaneously when a smooth hydrophobic surface is submerged in wate...

Micron-sized lipid-stabilised bubbles of heavy gas have been utilised as contrast agents for diagnostic ultrasound (US) imaging for many years. Typically bubbles between 1 and 8 μm in diameter are produced to enhance imaging in US by scattering sound waves more efficiently than surrounding tissue. A potential area of interest for Contrast Enhanced Ultrasound (CEUS) are bubbles with diameters <1...

BACKGROUND The uncontrolled discharge of untreated ballast water, which is essential for a ship's optimal operation, one the major causes sea environmental pollution by shipping. Among disinfection methods available water treatment, ozonation commonly used method, but its performance limited rapid ozone auto-decomposition rate. Nanobubbles (NBs) technology has attracted much scientific interest...
